Binding Text or Value of Items in the ItemTemplate of RadListBox

Hello,

I have an ItemTemplate in my RadListBox with a Label and an anchor tag. I am not binding the a datasource to this RadListBox, rather adding RadListBoxItem one by one. I want the Text property of RadListBoxItem to be mapped to the asp:Label in the template and when I click on the delete anchor tag, the item should be deleted. Can someone help me on this?

<ItemTemplate

<span

<asp:Label Text="how to bind" runat="server"></asp:Label

</span

<span

>

           <

a href="#" onclick="how to delete">Delete</a></span

</ItemTemplate>

Thanks,
Saquib

Filter with MS DropDownList concept Issue - Unknown Server Tag

I need a little bit of insight on an "Unknown Server Tag" issue coming from the Filtering with MS DropDownList tutorial located at (http://www.telerik.com/help/aspnet-ajax/grdfilteringwithdropdownlist.html).

I've copied the Source provided there letter-for-letter to "Show Off" the RADGrid's capabilities compared to others. However, there are a few warnings and parser errors that are halting the development:

In designer, the gridview renders fine and the custom columns are editable. However at runtime the ASPX page displays a parser error for an unknown server tag custom:MyCustomFilteringColumn.

The two warnings in question are:

Element 'MyCustomFilteringColumn' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.

and

Generation of designer file failed: Unknown server tag 'custom:MyCustomFilteringColumn'

The one time it did not give these errors, it complained that columns about the column type.

Any insight on this? I'm using the Trial version at the moment, and the code is a carbon copy from the URL provided above. Development environment is Visual Studio 2008 with Service Pack 1.

Thanks for the support.

Drag and drop appointment freezes in Chrome

Hi all,
We have a strange problem with the Telerik Scheduler. The drag and drop event is working fine in FF and IE, but in Chrome it freezes after the first successful D&D. This is not the case in other browsers.
It is more strange that it doesn't throw any JS nor code behind exception. It looks like it doesn't invoke the event the second time the user tries to D&D any appointment on the scheduler. Reloading the page (f5, Ctrl +f5) seems to make the D&D available but once the user D&D something again, it freezes and he/she needs to reload the page again. This is causing a big problem knowing that our production release is coming soon.
I tried uprgrading to the latest 2011.2.915.40 version but that didn't solved the problem.
This issue has been awhile and maybe some of our team has already reported something similar but I wasn't able to find it.
I would really appreciate if someone can share a solution or experience how to solve this problem.

Thanks in advance

Best Regards

Scheduler

GridAttachmentColumn without DataSourceID

Hi All,
I am trying to use the GridAttachmentColumn in the Grid, but don't want to have to use an SQLDataSource control.
I have objects and data-layers for the retrieving and control of my file objects, so I was wondering how I fill out this column with the bound information from my datalayer (it is a DataSet)?
At this point, it seems I need to abandon this new column type and use ItemTemplates instead with a nested RadUpload control.
Anyone had any experience with binding this column programmatically?
Thanks,
Steele.

RadGrid paging is not working properly

I have a RadGrid on an aspx page that does not seem to page properly. Any attempt at pressing any of the paging buttons (Next page, Last Page, 2nd page, 3rd page, etc) causes a small dark flash on the screen but does nothing otherwise. A second attempt at pressing a button will cause the page to refresh without the grid even being rendered.

Really appreciate the help on this.

We don't want to hard code this width inside the table, please suggest some alternative way of doing it.

<HeaderTemplate>

<asp:Label ID="labelHSymbol" runat="server" Text="Symbol"></asp:Label>

</HeaderTemplate>

<table width="70px">

Using IE9 radeditor adds junk code

I have had multiple complaints from clients about this. The problem is that when you use mainly IE9 junk code will be added to the radeditor just by typing. I have even reproduced this in the RadEditor Demo just click into the ul (which by the way takes multiple clicks) and then press the backspace key. As soon as you do that you should see that the editor adds    (viewed by switching to source) for apparently no reason it didn't exist before pressing the backspace key and only exits after pressing the backspace key. In my editor I sometimes get 8 or 9   when pressing the backspace key. Also I have seen (usually when there is an unclosed tag) it adding between 3-8 </div> or closing tags when only one is necessary. However that is on save and then looking at the code in the editor again. I am also doing a Server.HtmlEncode(RadEditor1.Content) and storing that in the database. Let me know if there is a fix for this other than forcing IE8 compatibility mode.
