I have create new webpart and widget for insert content via Page Tab. In my code I using asp:Literal for to get content from widget.
a issue when I insert Online-Form into content editor my widget not display validation.
/// <summary>
/// Content
/// </summary>
public string Content
{
get
{
return ValidationHelper.GetString(GetValue("Content"), LiteralCotent.Text);
}
set
{
SetValue("Content", Content);
LiteralCotent.Text = value;
LiteralCotent.EnableViewState = ControlsHelper.ResolveDynamicControls(this);
}
}
any idea?
Thanks, Vuthy
We can set the validation for online-forms.
Steps to set validation :-
1. Goto Forms module ==> click on your form.
2. Goto fields tab & select the which filed you want to apply the validation.
3. Right side it shows the properties of the filed and validation also.
4. If existing validation rules are apt your requirement go with it otherwise go with the regular expression.

How do you detect if, when using LightSwitch, the detail page is in Add or Edit mode?
I want to change the title of the screen from AddEdit Customer to either 'Add Customer' or 'Edit Customer'.
I can get screen.detail.dispayName = "Something". i need to know how to detect if it is in Add or Edit mode.
This is valid for HTML5 lightswitch -
There is Javascript namespace "msls" which encapsulates the LightSwitch JS framework to obtain the equivalent of EntityState.
The intellisense does not work so well, so if you keep getting screen.(nothing), add the following:
/// <reference path="../GeneratedArtifacts/viewModel.js" />
On the main event, add:
myapp.Customer.created = function (screen) {
if (screen.Customer.details.entityState == msls.EntityState.added) {
screen.details.displayName = "Add Customer";
} else {
screen.details.displayName = "Edit Customer";
}
}
where Customer is the dataset for the AddEdit HTML5 Lightscreen page.
I have some regular input webpage where users type in some details about item.
Then after the user presses the submit button she is redirected to a webpage saying that everything went fine. The problem is that if she clicks the back button then the input page is displayed again, and if she hits the sumbit, the form is re-submitted and another item is being written to the database, which is not desirable, of course.
I'm using ASP.NET MVC in C#. What is the best-practice way to deal with this situation?
You can create a hidden form element that marks the form as unique. Each time the form is written by the server, create a new random unique value. When the form is submitted, have the server check that the identifier has not been used before.
The problem is if you want to allow the user to press back and re-submit to create a second entry, there is no way to tell if the user intended to make a second copy or not. What you could do in this situation is make a link which takes the user to the same form, but with a newly generated hidden form element containing the unique identifier.
You can use TempDate and a hidden form value to both store a unique token, and compare them on the postback.
Like this:
public ActionResult FormDemo()
{
var guid = Guid.NewGuid().ToString();
ViewData.Model = guid;
TempData.Add("guid", guid);
return View();
}
[HttpPost]
public ActionResult FormDemo(string name, string guid)
{
if(guid != (string)TempData["guid"]) return new HttpStatusCodeResult(500);
return RedirectToAction("FormDemoReceipt");
}
public ActionResult FormDemoReceipt()
{
return Content("Form submitted OK!");
}
My FormDemo view looks like this:
#using (Html.BeginForm())
{
#Html.Hidden("guid", Model)
#Html.TextBox("name");
<input type="submit"/>
}
We're using Exchange Web Services to set user signature in Outlook Web Access. It works great, we see the signature under Options>Settings and the "Automatically include my signature on messages I send" check box is checked. We also set this programmatically.
However, when the user creates a new e-mail message in OWA the signature does not show up. A work around for this is to go to Options>Setting, uncheck the "Automatically include my signature on messages I send" check box , Save, check the check box again and save.
The code we use to set the signature looks something like this:
Folder rootFolder;
UserConfiguration OWAConfig;
rootFolder = Folder.Bind(service, WellKnownFolderName.Root);
OWAConfig = UserConfiguration.Bind(service, "OWA.UserOptions",rootFolder.ParentFolderId, UserConfigurationProperties.All);
OWAConfig.Dictionary["signaturehtml"] = "Hello World";
OWAConfig.Dictionary["autoaddsignature"] = "True";
OWAConfig.Update();
Any idea how to get around this problem?
I have some old code that does the same thing which is working fine. I have pasted the code below. There are a few minor differences between my code and yours. I am not sure if they make a difference but you may want to try it out. Here is an extract of my code with the differences highlighted with a comment:
private void SetSettingValue(UserConfiguration owaConfig, string propName, object propValue)
{
if (owaConfig.Dictionary.ContainsKey(propName))
{
owaConfig.Dictionary[propName] = propValue;
}
else
{
// Adds a key if it does not explicitly exist.
// I am not sure if it makes a difference.
owaConfig.Dictionary.Add(propName, propValue);
}
}
public void AddSignature()
{
// Extract
UserConfiguration OWAConfig = UserConfiguration.Bind(
service,
"OWA.UserOptions",
WellKnownFolderName.Root, // Binding to Root and not Root.ParentFolderId.
UserConfigurationProperties.Dictionary // Binds to Dictionary and not to All.
);
SetSettingValue(OWAConfig, "autoaddsignature", true);
SetSettingValue(OWAConfig, "signaturehtml", html);
OWAConfig.Update();
}
I'm still pretty new to Grails and I'm developing an online survey. I decided to use web flow and I have been running into many issues. I'm trying to pass the survey id from the gsp page to the flow controller. This works perfectly fine on any other controller action but whenever I do it to the action for the start state of the flow I always get the same error. I've followed a tutorial in a text book that does this the EXACT same way and I'm running out of ideas.
here is the link from the gsp page:
<g:link controller="surveyPage" action="beginTest" id="${survey.id}">
${survey.surveyName}
</g:link>
and here is the flow with the start state
def beginTestFlow = {
showSurvey{
def survey = Survey.get(params.id)
on("cancel").to "cancelSurvey"
on("continueSurvey").to "nextQuestion"
}
cancelSurvey { redirect(controller:"surveyPage") }
}
it always throws the exception:
argument type mismatch on the line with
def survey = Survey.get(params.id)
I've also tried:
flow.survey = Survey.get(params.id)
or even:
flow.survey = Survey.get(session.survey.id)
always the same error. Also, I made sure class Survey implements Serializable. I've copied and pasted the same code into a different action with the same controller and it works flawlessly. Any ideas to what is different with the web flow?
You can't put code like that directly inside a state definition, you need to use an action state or an onEntry block
def beginTestFlow = {
showSurvey{
onEntry {
flow.survey = Survey.get(params.id)
}
on("cancel").to "cancelSurvey"
on("continueSurvey").to "nextQuestion"
}
cancelSurvey { redirect(controller:"surveyPage") }
}
The onEntry block will fire every time the showSurvey state is entered. If instead you want some logic to be run just once at the start of the whole flow (for example if some later transition might re-enter the initial state), you can use a flow-level onStart block instead:
def beginTestFlow = {
onStart {
flow.survey = Survey.get(params.id)
}
showSurvey{
on("cancel").to "cancelSurvey"

I have a simple function that I want to call in the code behind file name Move
and I was trying to see how this can be done and Im not using asp image button because not trying to use asp server side controls since they tend not to work well with ASP.net MVC..the way it is set up now it will look for a javascript function named Move but I want it to call a function named move in code behind of the same view
<img alt='move' id="Move" src="/Content/img/hPrevious.png" onclick="Move()"/>
protected void Move(){
}
//based on Search criteria update a new table
protected void Search(object sender EventArgs e)
{
for (int i = 0; i < data.Count; i++){
HtmlTableRow row = new HtmlTableRow();
HtmlTableCell CheckCell = new HtmlTableCell();
HtmlTableCell firstCell = new HtmlTableCell();
HtmlTableCell SecondCell = new HtmlTableCell();
CheckBox Check = new CheckBox();
Check.ID = data[i].ID;
CheckCell.Controls.Add(Check);
lbl1.Text = data[i].Date;
lbl2.Text = data[i].Name;
row.Cells.Add(CheckCell);
row.Cells.Add(firstCell);
row.Cells.Add(SecondCell);
Table.Rows.Add(row);
}
}
Scott Guthrie has a very good example on how to do this using routing rules.
This would give you the ability to have the user navigate to a URL in the format /Search/[Query]/[PageNumber] like http://site/Search/Hippopotamus/3 and it would show page 3 of the search results for hippopotamus.
Then in your view just make the next button point to "http://site/Search/Hippopotamus/4", no javascript required.
Of course if you wanted to use javascript you could do something like this:
function Move() {
var href = 'http://blah/Search/Hippopotamus/2';
var slashPos = href.lastIndexOf('/');
var page = parseInt(href.substring(slashPos + 1, href.length));
href = href.substring(0, slashPos + 1);
window.location = href + (++page);
}
But that is much more convoluted than just incrementing the page number parameter in the controller and setting the URL of the next button.
You cannot do postbacks or call anything in a view from JavaScript in an ASP.NET MVC application. Anything you want to call from JavaScript must be an action on a controller. It's hard to say more without having more details about what you're trying to do, but if you want to call some method "Move" in your web application from JavaScript, then "Move" must be an action on a controller.
Based on comments, I'm going to update this answer with a more complete description of how you might implement what I understand as the problem described in the question. However, there's quite a bit of information missing from the question so I'm speculating here. Hopefully, the general idea will get through, even if some of the details do not match TStamper's exact code.
Let's start with a Controller action:
public ActionResult ShowMyPage();
{
return View();
}
Now I know that I want to re-display this page, and do so using an argument passed from a JavaScript function in the page. Since I'll be displaying the same page again, I'll just alter the action to take an argument. String arguments are nullable, so I can continue to do the initial display of the page as I always have, without having to worry about specifying some kind of default value for the argument. Here's the new version:
public ActionResult ShowMyPage(string searchQuery);
{
ViewData["SearchQuery"] = searchQuery;
return View();
}
Now I need to call this page again in JavaScript. So I use the same URL I used to display the page initially, but I append a query string parameter with the table name:
http://example.com/MyControllerName/ShowMyPage?searchQuery=tableName
Finally, in my aspx I can call a code behind function, passing the searchQuery from the view data. Once again, I have strong reservations about using code behind in an MVC application, but this will work.
How to call a code-behind function in aspx:
<% Search(ViewData["searchQuery"]); %>
I've changed the arguments. Since you're not handling an event (with a few exceptions, such as Page_Load, there aren't any in MVC), the Search function doesn't need the signature of an event handler. But I did add the "tablename" argument so that you can pass that from the aspx.
Once more, I'll express my reservations about doing this in code behind. It strikes me that you are trying to use standard ASP.NET techniques inside of the MVC framework, when MVC works differently. I'd strongly suggest going through the MVC tutorials to see examples of more standard ways of doing this sort of thing.
