I'm trying the following:
<div id='divOwner' runat=server visible='<%# isAccountOwner(Me.UserId) %>'>
I would expect this to switch visible / invisible based on the value of isAccountOwner. This is not working as expected, and is always coming up visible. Can somebody enlighten me please?
Thanks
#in code nuggets (<% %>) is used with data bound controls like gridview, repeater control etc. For your div to work like this you need to call the DataBind method of this Div or one of its paremt control.
So, In page load include this line:-
divOwner.DataBind();
And make sure isAccountOwner returns a Boolean.

In html am rendering some value in the and passing it as a input to a component like
below
<test-component
[title]= "data?.Kevin?.title"
</test-component>
Please be noted data?.Kevin?.title will give the title name.How ever, in the above, I want to render the name a bit dynamically like below
<test-component
[title]= "data?.{{name}}?.title"
</test-component>
{{name}} should render kevin and the tile value needs to be passed to the component.
Here the name is not being rendered correctly.
Any help is highly appreciated.
the solution is pretty simple: [title]= "data?.[name]?.title"
the equivalent of the first example would be: [title]= "data?.["Kevin"]?.title"

I'm trying to get ag-grid's height to match the content.
I have several sets of data which I'm trying to load into different grids, each with the appropriate height for the data.
There is an AutoHeight option but the Angular version doesn't seem to work (I'm assuming this is for a previous version).
Here is my alternative attempt, which doesn't work:
<ng-container *ngFor="let reportItem of reportData">
<br />
<ag-grid-angular style="width: 100%; height: {{ 560 + (reportItem.data.length * 40) }}px;"
class="ag-theme-material bold-headers"
[rowData]="reportItem.data"
[columnDefs]="columnDefs">
</ag-grid-angular>
</ng-container>
Does anyone have a better suggestion?
Rather than just linking to the Auto-Grid Height method I described at the top - which I tried and failed with, could you please explain how I should implement it with my code above? (as I accept I may have missed something)
Thanks
There is the setGridAutoHeight method available on the api object. You need to get a reference to that object from the gridReady event and then you can call it, passing true to it. You have to take care with it if your data has many rows because using this method all the rows will be rendered to the DOM, normally only the visible ones are rendered.
gridApi.setGridAutoHeight(true)
It's at the bottom of the page: https://www.ag-grid.com/javascript-grid-api/
according to this link you can use domLayout='autoHeight' as a property to your grid.
it worked for me.
so iam trying to add a image i have saved on my project in image folder. But it dosent work
DirectCast(Customer.Items(0).FindControl("imageControl"), Image).ImageUrl = "~/images/IMG_1287.JPG"
DirectCast(Customer.Items(0).FindControl("imageControl"), Image).DataBind()
customer is the repeater html element the image element is in. I cant call the image element direct in the server code because the image element is inside a repeater element. So i have to use findcontrol method which works good. When i debugg the code i can se that it finds the right image element the problem is when i set the imageurl nothing seems to happen in the ui but i dont understand why can anybody help me please :)
<div>
<asp:Image ID="imageControl" Width="100%" Height="70%" runat="server"/>
</div>
To me it looks like you are not trying access controls within repeater in correct manner , it should be like :
If image is in header :
DirectCast(Customer.Controls[0].Controls[0].FindControl("imageControl"), Image).ImageUrl = "~/images/IMG_1287.JPG"
If image is in footer
DirectCast(Customer.Controls[Customer.Controls.Count - 1].Controls[0].FindControl("imageControl"), Image).ImageUrl = "~/images/IMG_1287.JPG"
Please have a look at this post for more details.
PS : Are you using vb ? cause i have used C# syntax, if yes change accordingly.
Some background information, I am using ASP.NET with the MVC framework and html helpers.
I currently have a dynamic table where each row has a series of input boxes. Each of these input boxes has a validation message. This works completely fine for the first row. However, when other rows are dynamically added (with the IDs' being changed along with other attributes to match the row number) the validation message no longer works.
Both the row and validation message span are being replicated properly.
In JQuery, this is usually just a problem with the binding, so for each row I would simply re-bind the IDs'. However I am not really to sure how to approach them in ASP.NET.
Any assistance would be appreciated.
Thanks
Alright, I have finally figured this out.
In MVC, in order to handle the validation, it import a JQuery file known as jquery.validate.unobtrusive.js.
However, similar to JQuery, this only occurs at the very beginning when the page is loaded. So, when you add a new dynamic element, you need to remove the bindings and the re-bind them again.
Basically, in your function for adding a new element, put the following lines of code AFTER you have added the new element:
$("#form").removeData("validator");
$("#form").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse("#form");
For example:
function addInfoDynamic()
{
document.getElementById("#myDiv").innerHTML += "New Content";
$("#form").removeData("validator");
$("#form").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse("#form");
}
I want dynamically add text-box in html page when user is press a button. and after that i want to get the respective field value or all field value.
I tried doing ng-repeat but it will not work. can anyone tell me how i will achieve this.
I would indeed use ng-repeat, and just push a new object onto the array. Maybe something like this?
<button ng-click="textFields.push("")">Add</button>
<textarea ng-repeat="val in textFields" ng-model="val"></textarea>
Well there are a few things you could try. One of them is loading a hidden div when clicked on the button. The hidden div contains the text box.
Like this :
$(document).ready(function(){
$("#hiddendiv").hide();
$("#button").click(function(){
$("#zmedia").show();
}};
And in your html form you just add a div that contains a textbox and the id of the dive should be "hiddendiv". The downside is that once the hidden div is loaded, it cant be removed. There are other scripts that are a lot more sophisticated, check these links out:
