I've created a custom implementation of the RadComboBox control and I'm having problems after postback. Seems the ItemTemplate is lost after the page posts back and the ItemText is what shows in the list instead of the ItemDescription I've specified. Here's my code:

//I do not want to reload data after postback so I check to see if items have already been loaded
    if (MyCustomComboBox.Items.Count < 1)
    {
            MyCustomComboBox.DataTextField = "ItemText";
            MyCustomComboBox.DataValueField = "ItemValue";
            MyCustomComboBox.DataListField = "ItemDescription";
            MyCustomComboBox.DataSource = CEarn.GetECodeList();
            MyCustomComboBox.DataBind();

            MyCustomComboBox.Items.Insert(0, new RadComboBoxItem("Select One...", String.Empty));
    }

Hello

which skin included in the release is the litest?

Hi. Using

I utilize the telerik demos as a "proof of functionality / configuration" much of the time.  I know if I my code does not work, yet I can pull up a telerik demo that utilizes pretty much the same code, then the error is on my config end.

However, I discovered today that IE8 cannot utilize the in-line editing found at

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultvb.aspx



The grid is basically "dead" and can't even utilize the raddropdown - which is an issue I'm having with a SEPARATE project on certain machines with IE7- but I thought for sure it was my config.

The IE8 version is 8.0.6001.18702 and I am on XPSP2

Any suggestions ? Has this demo been vetted against IE8?  Will my RADcontrols function against IE8? I'm including the meta tag to force IE8 into IE7 compatibility mode, but I am still having the "javascript death" issues.

Thanks!!

We are having major issues with the Rad Editor. Opera 9.64 (PC/Mac), doesnt render the editor itself correctly, therefore you cannot even type into the box. Firefox 2.0.0.16 has issues rendering the rad toolbar. Safari 3.1.2 uses completed different markup than FF and IE. Even when I specify a new line type it (Safari) still uses "div" tags.

Are there known issues with these browsers? Do i have to do something special to get them to work?

I was looking for a way to adjust the format of the radcontrol.  In the radcontrol, I want to have different tests with different questions.  Each test ranges from 10-20 questions.  20 questions across is too much to display in a radgrid, so I was wondering if I could display the questions on top of each other as opposed to side by side.  Is this possible?

Hi,

I'm using RadEditor in a Windows SharePoint Services custom column (I don't use RadEditorMoss, but the RadEditor 2008_Q3 for Ajax ASP.Net ... simply because I had to activate some features depending on WSS rights, which isn't possible with RadEditorMoss).

I saw that topic : http://www.telerik.com/community/forums/aspnet-ajax/editor/why-does-toggle-full-screen-take-so-long-in-ie-7.aspx

I tested today the online demo and my implementation of the RadEditor. I got :

- something like 5s in the live-demo. that's acceptable.
- something like 30s in my implementation in WSS in IE7
- something like 10s in my implementation in WSS in FF3

I saw in the topic reported below that this issue was pinned, and may be improved in 2009. Has this feature been improved in the last release ? If not, how can I improve my use of the RadEditor in WSS ? Did you do something special for the RadEditorMoss ?

Thanks in advance for you answer.

Hello,

My functionality is Before selection start i want to insert one symbol & after selection end also want to insert one symbol. for that purpose i want the exact position of selection start & selection end.


Thanks,

My question is how do you prevent wrapping of items in the grid. When the grid has lots of columns it causes the icons to wrap.
See http://www.creditbootcamp.com/grid_tools.png

We tried:   
<rad:GridTemplateColumn UniqueName="Tools" HeaderText="Tools" ItemStyle-Width="150">
But it did not work. Putting the icons in a table did work but caused borders to show up around the table (which we dont want).

We want the icons to stay on the same line and not to page break.


Thanks guys!!

I want to get the date range of a week from a client side RowHeaderClick event (so that I can send it in a web services call).

Hi. I've got a RadTabStrip with a few RadMultiPages. In IE7 if I set the following style the vertical scroll bars appear on page load but when I click on to another tab then back on to the first tab the scroll bars aren't there. If I click onto another tab then back onto the first tab again the scroll bars are there. If I repeat the same process over the same behavior occurs.


It checks out okay in IE6, IE8 and FF3.
