Editor-Control stops working when placed inside an ItemTemplate. See the example below. Editor1 is outside the ItemTemplate, Editor2 inside. When I remove the comments of Editor2, both Editors will not render correctly in the browser. Placing Width= and other properties did not result in a working editor-control.

I am having big trouble with this issue, getting a message from IE that a script is being running for a long time and asking me to stop it myself.
The HTMLEditor seems to be uncomptible with this one.
I am also getting a very weak performance when adding this Ajax control.
I think this control is very heavy, but I'm not sure. If I am not wrong, this post I'm writing is inside the same control and I can see it takes time to load it in my page.
I have something like this:

This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.

View 1 RepliesI am fairly new to web development & stuck up using the ajax:popupExtender inside a gridview/Itemtemplate. So, would like to get help from experts in the forum
[Code].....
Currently I m developing a web page which holds a grivview. As one of the column needs a multiple column dropdown with soring facility, I am using ajax:popupExtender to achive that. Basically in the column i have a Panel1(label & image which mocks up has a dropdown), ajax:popupExtender, Panel1(gridview to have mutiple column). When user clicks on it the ajax:popupExtender is called & the targetpopupid which is a panel2 with gridview is called.
Here when user clicks on thePanel1, I am able to display Panel2 using ajax:popupExtender. Also, when user selects some row, I am able to close/hide the ajax:popupExtender in the code behind using cancel(). (this is done in selectItemIndexchange of panel2 grid view).
But my problem comes when user doesn't select any row & clicks back on the panel1, the ajax:popupExtender will remain open. but it should have been closed as i am trying to mock up dropdown dunctionality. how can I hide/close ajax:popupExtender when user clicks on panel1 2nd time.
Following are the different approaches I tried but nothing worked out.
1. wrote JS, & tried to add attributes of the Panel1's onclick event.
Failed: Error - Object is undefined. even though i passed a valid obj from code behind.
<script language="javascript">
Autocompleteextender not working inside an user control tried all ways. i have a custom function.. inside the cs file itself like the following :-
[Code]....
I did something like this and it worked properly when it was in aspx but when i changed all this to ascx and when i added the user control in aspx the autocomplete is not working. say enablecontext = false; i have even tried that.. its not even reaching till that function. moreover i need contextkey to validate different autocomplete controls inside my page.
Inside repeater's itemtemplate I have a Panel server control.I need to assign special Id for it, because I need to work with some javascript functions that use this Id.
In repeater ItemDataBound event I have this:
pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID");
But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback)
I tried to set the ID on aspx page like that:
<asp:Panel id='<%# Eval("ID") %>'
and some other variations but always get compile errors.
How do I create and control the content of a div inside a cell of an itemtemplate in a gridview?

I'm using AJAX Control Toolkit HTMLEditor.
I have a sample Microsoft Word document which has several paragraphs.
When I click the button "Paste from MS Word (with cleanup)" on the Editor, <br/> is inserted as the HTML instead of <p></p> i.e. HTML paragraphs.
I would like the MS Word paragraphs to retain their meaning and have a <p> instead of <br />.
(By the way, they are kept if I do a standard Paste, but then a lot of other obscure characters are inserted into the HTML)
I have a few issues with the HTMLEditor control.
First, if I type an e-mail address into the HTMLEditor control, it automatically reformats the e-mail address into a link (underlined w/ blue font). How can I disable this feature?
Second, is there a way to prevent pasting into the HTMLEditor? I successfully got Internet Explorer to throw errors when I copied & pasted the entire page, HTMLEditor and all, into the HTMLEditor control. Since the page already contained a PageRequestManager, the data I pasted into HTMLEditor contained its own code for a PageRequestManager. As a result, unsurprisingly, I got the following IE error:
Error: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.
Is there a way for me to prevent these strange situations from occurring?

If i use signs like ë in the HTML Editor, in IE, its ok, and works. But if i use ë in firefox in the same page with the HTML Editor. If i press safe the ë is converted to: � (copy past doesnt work well, but its a square if you put [] to each other). But how is this possible? And how can i solve this problem? In IE its working well, but 50% of the users of the system i build are using Firefox. So it should work in all editors.

I have a project where I'm rebuilding a legacy app and need to combine multiple similar web pages onto one ASP.Net web form. I thought I could easily do this with MultiView / View groupings. The problem I'm encountering is that each View control doesn't isolate controls of the same name.For example, I wanted to do this:
<asp:View ID="view1" runat="server">
<asp:Label ID="TEXT01" runat="server" />

I have a FormView inside a user control, and in the InsertItemTemplate, I have an AsyncFileUpload control, that I would like to to use. On the user side, it seems to work, but it doesn't work on the server side code behind. The HasFile Property is always false, and it doesn't fire the UploadCompleted event either. My UpdatePanel is in the master page.
<asp:FormView
ID="frmAddImage"
runat="server"
DataKeyNames="imageID"
DataSourceID="sqlImages"
Width="100%">
<InsertItemTemplate>
<cc1:AsyncFileUpload
runat="server"
ID="FileUploadImage"
Width="400px"
UploaderStyle="Traditional"
CompleteBackColor="Lime"
ErrorBackColor="Red"
onuploadedcomplete="AsyncFileUpload_UploadedComplete"
UploadingBackColor="#CCFFFF"

I have a user control.The User control contains many DIV tags. Each DIv contains update panel and javacript.At a time only one DIV is visible.
Visibility is handled in c# code behind. Show the second DIV by clicking on a button in first DIV.The user control is in another update panel.
When showing the second DIV the JavaScript inside the second DIV is not working.
The following is not working (does a full postback). Note: HTML tags inside updatepanel. We can' t have HTML tags inside updatepanel? If so, what's the work around?
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<td><asp:DropDownList ID="ddlDEPT_ID" runat="server" AutoPostBack="true"></asp:DropDownList></td>
<td><asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label></td>
<td><asp:DropDownList ID="ddlSUB_DEPT_ID" runat="server"></asp:DropDownList></td>
</ContentTemplate>
</asp:UpdatePanel>
The following works fine. AJAX in action.
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:DropDownList ID="ddlDEPT_ID" runat="server" Width="200px" AutoPostBack="true"></asp:DropDownList>

[Code].....
I have a user control which is used to display search results. The HTML for each result displayed will vary based on the type of result being displayed: "contacts" are displayed in one way, "news articles" are displayed in another, etc. There are around 10 different types of results that are all marked up differently when they get to HTML — so I need around 10 or so different templates for individual results that I can choose between based on the current item being displayed.
I'm using an asp:Repeater to display the results, but I don't know how to select the appropriate template within the asp:Repeater <ItemTemplate>. Ideally I'd like the ASP to select the appropriate template to use based upon the object type being passed in via the searchResultsRepeater.DataSource — but unfortunately I can't use switch on type (see this blog entry for C# switch on type). I can however just pass through an enum value for the type of result being displayed.
In the backend C# code I have an abstract inline SearchResult class, and children of that class like ContactSearchResult, NewsArticleSearchResult, etc. The searchResultsRepeater.DataSource would then be bound to a List<SearchResult>. Each SearchResult contains a ResultListingType type field which gives the type of the listing to be displayed.
Attempt 1: using control flow inside the ASP itself
My first attempt was something like this:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<% switch (DataBinder.Eval(Container.DataItem, "type")) { %>
<% case ResultListingType.CONTACT: %>
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
<% break; %>
<% case ResultListingType.NEWS: %>
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
<% break; %>
<% Case AnotherTypeOfListing1: %>
<% Case AnotherTypeOfListing2: %>
<% Case AnotherTypeOfListing3: %>
<% Case AnotherTypeOfListing4: %>
<% Case AnotherTypeOfListing5: %>
<% etc... %>
<% } %>
</div>
</ItemTemplate>
</asp:Repeater>
Unfortunately, this doesn't work:
"switch" and "if" both give "invalid expression term" inside the <%# ... %> brackets.
"Container.DataItem" gives "the name "Container" does not exist in the current context" inside <% ... %> brackets.
Attempt 2: setting asp:PlaceHolder's to Visible = False
I found something that looked useful at how to change the ItemTemplate used in an asp:repeater?. I then tried something like:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<asp:PlaceHolder ID="newsResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
</asp:PlaceHolder>
<asp:PlaceHolder ID="contactResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
</asp:PlaceHolder>
</div>
</ItemTemplate>
</asp:Repeater>
In my ItemDataBound event I did:
Control newsResultListing = e.Item.FindControl("newsResultListing");
newsResultListing.Visible = false;
Control contactResultListing = e.Item.FindControl("contactResultListing");
contactResultListing.Visible = false;
switch (item.type)
{
case ResultListingType.CONTACT:
contactResultListing.Visible = true;
break;
case ResultListingType.NEWS:
newsResultListing.Visible = true;
break;
default:
throw new Exception("Unknown result listing type");
}
Unfortunately this doesn't work because ASP seems to still be running the contents of the PlaceHolder even after I set Visible = false. I get the error "DataBinding: 'usercontrols_ResultsListing+ContactResultsListing' does not contain a property with the name 'newsHeadline'" — i.e. the newsResultListing PlaceHolder is still looking for the "newsHeadline" field, even though that field doesn't exist for the result listing type being displayed.
In fact I've tried a quick test throw new Exception("e"); in my ItemDataBound, and it looks like the "DataBinding" error is thrown even before control flow gets to the ItemDataBound method, so there's really nothing I can do in there to avoid this error.
I suppose I could add every single field to the parent class and leave most of them null in my children, but that seems really ugly.
Is there a way to make this work, or an easier way to vary my ItemTemplate based upon the type of Container.DataItem I'm currently iterating over? I'm very new to ASP so there's likely something simple that I've missed.
