Does anyone have any luck adapting Draft.js for Reagent? There's pretty heavy editing issues if Draft.js is imported right away via reagent/adapt-react-class. Cursor jumps, disappearing symbols when you're typing, onChange calls with incorrect EditorState, you name it.
People are reporting problems like this in clojurians/reagent Slack channel, but it seems there's no solution so far.
Any help would be greatly appreciated.
Okay, thanks to tonsky, I got the answer. Reagent/Rum are using deferred rendering with requestAnimationFrame, but Draft.Editor should be re-rendered immediately when editorState is set.
All we need is to call forceUpdate for editor parent component whenever editor onChange is invoked:
:editorState #editor-state-atom
:onChange (fn [new-state]
(reset! editor-state-atom new-state)
(.forceUpdate #wrapper-state))
Code example is for Reagent, solution for Rum is identical
Just an idea (more of a comment, but I can't provide comments yet), because -- if I remember correctly -- the :content-editable attribute is treated in a special way within Reagent:
Since the problems seem to occur when the Draftjs editor is called from Reagent, would it not help to convert the Reagent-component to a React-component (using reagent/reactify-component), and then use this "reactified" component as a react-component within Reagent, using reagent/create-element? I would assume that Reagent then refrains from meddling with the Draftjs editor.

Here is the website I am trying to access. I dont want the default tab (Day) though, I want to select the Season tab
https://www.eex.com/en/market-data/power/futures/uk-financial-futures#!/2017/05/23
The link appears to be exactly the same whichever tab is chose making differentiation impossible as far as I can tell.
Any help on this would be much appreciated, using whichever programming method and language is appropriate.
Kind Regards

The URL does not change since this is an ajax request, which you can see from MarketDataTableAController's getPageData function. You can read about them here https://developer.mozilla.org/en-US/docs/AJAX/Getting_Started
Ive inspected your html and you seem to be using angular. On further inpection you can see that the tabs have ng-click="setActiveTab(tab)" attribute on them. So whenever user clicks, this function gets executed. It is a matter of using this function with the appropriate tab object to get the content to change. You for example could put setActiveTab(tab) into your controller init method since setActiveTab() calls the forementioned getPageData() function to update the page.
Also the tab you are looking for is page.tabs[5] ($parent.page.tabs[5] if referring from TabController) since this is the tab with the label of season. Pass that to setActiveTab() and it should show you the season instead.
However this might not be a good solution since the tab array ordering might change. Then you would need to loop over all objects in page.tabs and see if tab.label === "Season" and pass that in the function instead or better yet use the $filter service provided by angular which would look more cleaner.
Your code source also seems to be minimized and its not very easy to read.
I was working out a problem with a ddl trying to get a message box to popup when the item changed. You can read about that here >>>
How to Popup Alert() from asp:DropDownList OnSelectedIndexChanged?
The working answer shows me to use the onchange event but then I'm working in VS2010 this event does not appear in the intellisense dropdown. However if I type it in anyway it works fine.
For this, you need to understand how the thing works....when you change the value of a input element, onchange event gets triggered on the browser, so the browser looks for a way to handle it. So when you put the onchange event specified for the element it gets called.
Now, ASP.NET OnSelectedIndexChanged uses the same functionality(logically saying) to POST the page to the server. From there, the ASP.NET runtime triggers the function you wrote in the codebehind file and returns you the result. Now, if you really don't require any operation that can only happen on the server, you don't need to use the server functionality, instead you can do it in javascript.
On the other hand, if you want something that happens on server: like some database get, you are supposed to use the OnSelectedIndexChanged event.
And if you use the OnSelectedIndexChanged event, you can still call some javascript functions from there.
Page.ClientScript.RegisterClientScriptBlock(typeof(string),"myScript","alert('HI')",true);
To answer your question about intellisense, onchange is a event of input types, and in aspx pages, i guess you are using <asp:..> tags, which does not have the same event - thus visual studio does not show it in the intellisense. But when you put it, it gets assigned to the HTML markups, which is interpreted correctly by the browser.
PROS and CONS
onchange works on your browser, so it is lot faster than the server-side code. On the other hand, we had an issue once that the browsers has the capability to restrict pop-ups. So if you want some really important message to be shown, it is better to use the Server-Side event and the RegisterClientScriptBlock function.
Hope it helps.
In VS 2015, only when in Razor (.cshtml) files, roughly half of the time the autocomplete/suggestion list/intellisense doesn't work correctly (sorry, not sure the actual term... when you type an object and hit . and the list of properties and methods shows to select from)
The behavior is that when I hit ., the list popups up for a fraction of a second and then closes. It happens so fast I try to do a quick Backspace, ., Backspace, . cycle a few times to at least see the name I need, but I usually cant' get it and end up having to find the exact name elsewhere from code. Extremely irritating...
It happens sporadically with no real pattern I can find. Here's patterns that I've ruled out:
The file that's open doesn't seem to matter.
Whether or not I close/reopen the file doesn't seem to matter
Whether I navigate to another file and back doesn't seem to matter
It will work/not work multiple times on and off throughout the same file
It doesn't seem to be relevant to any particular object/property/method
I've checked all my options (there doesn't seem to be Text Editing options for Razor?), have tried clearing caches, the reloading solution/projects, restarting VS, all of which seem to still provide no pattern.
Has anyone come across this and have any ideas of where else I can look to fix it?
Example
Here's an extremely simple example... new project, very little code/files, very simple view. Where the Model. stops, I should have the usual base methods, and an 'Items' collection. It pops up for a split second then disappears... no lambdas/complex view parsing involved (this is reproducible as well):
Update: Patterns
Things I've noticed:
If I'm entering a #model ns.ns.ns.type, it rarely happens toward the "base" end of the namespaces. It's as I get further towards the type that it happens. This one is intermittent.
In some cases, it works perfectly fine, every single time. For example, I often use DevExpress tools, and have never seen the behavior on any of their extensions (so, #Html.DevExpress(). (and other similar, not necessarily DevEx models) will never cause a problem)
It happens almost all the time when I'm accessing my #Model (which is where I most want it!). I've found some cases where this is reproducible every time (see above example), but it's about 90%+
Occasionally, as I work through the object tree, one will fail while the next works (ex: #models ProjName.Web.App.Subscriptions.Models.AccountCreateVM... it might fail on Subscriptions but work fine on Models)
Occasionally, beginning to type the name within autocomplete kicks it back into gear and it starts working again. In the above example, starting to type Acc for AccountCreateVM causes it to start working again.
I haven't found the root cause, but in all cases, CTRL+SPACE works. This isn't the best, but light years better than nothing at all.
(this shortcut is not one I've used in the past, so this is likely standard behavior, but...) If you're at the dot Model. and autocomplete list disappears, CTRL+SPACE consistently brings it back up, and when it does come back, it stays! If there's only one possible autocomplete member, it'll auto-fill the member for you upon CTRL+SPACE
This happens for me all throughout VS2015 during lambda statements.
It happens when editing code "mid-document", as in, if there is anything besides a ) or } following where I'm typing. VS appears to be struggling to tell where the current statement ends & the next statement begins.
The following code will consistently fail to trigger Intellisense at the period, even when explicitly invoked.
var subset = initialSet.Where(x => x.
var result = new Whatever();
In Razor, it is very common to be editing code between existing text and using lambda statements:
<strong>#Html.DisplayFor(m => m.</strong>
This is probably why you only experience this in Razor.
The way I work around this bug is just to write the ) to close the method.
var subset = initialSet.Where(x => x.)
var result = new Whatever();
<strong>#Html.DisplayFor(m => m.)</strong>
Intellisense can then be triggered on the period.
If you're using a method that requires a minimum of more than just the lambda (like RadioButtonFor), you'll also need to put in a comma for each of the extra parameters.
<strong>#Html.RadioButtonFor(m => m.,)</strong>
If Intellisense is appearing, but immediately disappearing again, the best solution I've found so far is to just type a few letters of any known member, then using Ctrl-Left to skip back to the period, and trigger Intellisense again (Ctrl-Space or backspace-retype). This usually gets it to appear and stay. You'll have to delete the characters you typed afterwards, which can be frustrating.
Just make sure the ) does not touch the text you are editing, and the popup will stay up.
Instead of...
#Html.Partial("ManageGrid", Model.)
Use...
#Html.Partial("ManageGrid", Model. )
The intellisense seems to get confused by touching close parenthesis. Not ideal, but this was the only way I could get it to work for me consistently.
In my specific case, i was able to solve the problem by installing the latest version Microsoft ASP.NET and Web Tools.
https://marketplace.visualstudio.com/items?itemName=JacquesEloff.MicrosoftASPNETandWebTools-9689
Once I installed it, the problem was gone. It is likely that this update fixed something that could be fixed with an older version, but either way I'm happy.
(I found this in Visual Studio under Tools->Extensions and Updates...->Updates->Visual Studio Gallery)
I had the same error and I fixed it by deleting all the files of the component model cache.
This is the path:
Users\YourName\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
Hope that helps
I use ctrl+j as a temporary solution when I know the content.
Or keep writing without right parenthesis can use the completion:
#Html.LabelFor(m => m.Name
Whenever this annoying thing happens to me, I just put an extra dot and then it works. I have to put the extra dot every time. For example, if I write this and intellisence flashes and disappears:
#Html.TextBoxFor(m => m.
then I just do this:
#Html.TextBoxFor(m => m..
And intellisense will now show after first dot. I have made this a habit until MS has a fix for it.
Instead of...
#Html.Partial("ManageGrid", Model.)
Use...
#Html.Partial("ManageGrid", Model.
I'm currently helping a small team create a HTML LightSwitch business app that has a tier of 4 Cascading dropdowns. These drop downs are linked together just as the common example of when you select your state it filters to cities only in that state. However, the issue that we have run into is that upon changing one of the parent boxes the child box doesn't reset or revert to a blank state. How would it be possible to accomplish, if possible, the clearing the child boxes upon parent change. Im pretty sure we need an OnChange event handler but I'm not sure where to put this in LightSwitch because it creates the code for you.
Any idea's or code snippets that are able to fix this problem would be appreciated.
Thank you in advance for the help,
Jeremy
I think you need a change listener event on page created method screen.addChangeListener("DropDown1",DropDown1Changed);
function DropDown1Changed(e){
screen.findContentItem("DropDown2").value ="";
screen.findContentItem("DropDown3").value ="";
};
I havent tested this code. But, something similar to this should work. This should give you general idea about the solution.
Dont forget to remove the listener.
Use pop-ups based on Queries instead of drop-downs. Make the parameters for your queries optional where necessary. LightSwitch will then update the page definition as selections are made. This is because the binding of the popup data values is done at run-time, whereas the binding for controls rendered when the page loads is static.
Michael Washington gives a pretty good summary of the technique in this article.
My current job is updating an existing Access97-Project. I haven't worked with Access in a long time and i can't find out, how i can explore a toolbar called "sbmbDrucken" which is obviously user-created. I just need access to the action or the code which is called by the buttons...
Is there any menu entry i missed or do i need special code for self-inspection?
TIA!
There are three different ways for menus/toolbars to be instantiated:
the old way, using macros. Before A95, this was the only way, so a lot of older apps (i.e., those converted from earlier versions) may still use macros for the menus.
defining them by hand, using the CUSTOMIZE function that you get when you right click on a toolbar in Access.
in code, using the Application.Commandbar object.
For the first you can browse your macros and see if any of them are menu macros.
For the last, you can do a search in the code for CommandBar.
For the second, just look at them through the built-in menu customization tools. Keep in mind that you may have to check them off to get them to be visible, and that the list is in no rational order. Likewise, some menus/toolbars are hidden from the customization interface. Also, you might need to look at the CUSTOM toolbar menu item.
I don't have Access 97 on hand but you may take a look of this webpage: http://www.alvechurchdata.co.uk/hints-and-tips/accaddtoolbar.html
It seems that "user-created" toolbars could be defined by handwritten code at form.load or somewhere similar. You may search CommandBars.Add and see if you can find those relevant code segments.
Hope that helps.
In the design mode, you will be able to see the toolbar & actions assigned to each of the button.
Right click on the specific toolbar
Click on Customize...
Right click on the button you would like to edit the action of.
You will be able to see the action (which could either be macro or code).
Let me know, if that doesn't help at all.
