I have attatched the both images as sample, please suggest me which css class to fix.

Before image is the display on first load,
After image is the display after page is loaded after post back it adds the balck borders :(

Help canceling postback in OnClientSelectedIndexChanged

I am updating some custom controls and am having trouble figuring out how to cancel a postback on a RadListBox from the

ClientSelectedIndexChanged

handler. To explain...I have a page that contains a RadListBox, a RadTabStrip, and a RadMultiPage which are all linked. When the user selects a item from the RadListBox I use the ClientSelectedIndexChanged handler to check if the linked Tab/PageView already exists and if so then set them selected...if not then they are created and selected server-side. I have a prototype version which uses a RadTreeView that works fine using the set_postback( false ) method on the node in the OnClientNodeClicking handler...does anyone know how to do the same with a RadListBox??

ajax functionality doesn't seem to be working

I've added a radlistview to a page, with a radrating control inside of it. It's displaying about 330 records.

I then went ahead and put the radlistview in an radupdate panel, but i can't see any difference in how the page behaves. I then went ahead and added a rad loading panel to the page. And still i can't see any difference to the page. I left initial delay and min display at 0, no effect. Changed min display to 2000, no effect.

Here's what my aspx markup looks like:

Is there an Interaction between OnRowClick and OnSelectedIndexChanged???

Hi

I have a Radgrid that has had OnRowClick working for some time on the client side.

I am now trying to wire up to the Server Side OnSelectedIndexChanged as well.

However I am not getting the server event when the user clicks on a row.

I DO get the event later if I click a button outside of my grid, for instance to close the RadWindow all of this is happening in.

What am I missing?

[Solved] Textarea in inline edit

I need to change the default small textbox to a textarea in edit mode ( inline) and it's not working, the textarea shows up when i use a template column but when it tries to update the textarea value it throws an error because it cannot find the value even though I set up Update params in the SQL datasource. Is there any sample projects that do this? I am wondering if it cannot find the value because I am using master pages.

Here is the code for the grid:

<telerik:RadGrid ID="rgNews" runat="server" CellSpacing="0"

DataSourceID="sdsNews" AllowAutomaticInserts="true" AllowAutomaticUpdates="true" AllowAutomaticDeletes="true" GridLines="None" AllowPaging="True"

AllowSorting="True" AutoGenerateColumns="False">

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

</telerik:GridBoundColumn>

<telerik:GridEditCommandColumn ButtonType="ImageButton" CancelText=""

</Columns>

<EditColumn FilterControlAltText="Filter EditCommandColumn column" ButtonType="ImageButton"></EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False"></FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

</telerik:RadGrid

>



Here is the SQL Datasource code:




<asp:SqlDataSource ID="sdsNews" runat="server"
       ConnectionString="<%$ ConnectionStrings:CLSWEBConnectionString %>"      
       SelectCommand="SELECT [newsID], [Title], [Date], [Author], [Publication], [Content], [Link] FROM [tblNews]"
       UpdateCommand="UPDATE [tblNews] set [Title] = @Title, [Date] = @Date, [Author] = @Author, [Publication] = @Publication, [Content] = @Content, [Link] = @Link WHERE [newsID] = @newsID"
       DeleteCommand="DELETE FROM [tblNews] WHERE [newsID] = @newsID">
       <UpdateParameters>
       <asp:Parameter Name="Content" Type="String" />
       </UpdateParameters>
   </asp:SqlDataSource>

Here is the error it throws, I am guessing it cannot find the value of the Content template column:

Cannot insert the value NULL into column 'Content', table 'CLSWEB.dbo.tblNews'; column does not allow nulls. UPDATE fails.
The statement has been terminated.

Thanks,
Sam

Upgrading from AJAX Q3 2009 to the latest version

I created a web forms application that used controls from AJAX Q3 2009. That application was never released at that time. Now we are planning to go back and start working on it again. I want to use the latest control versions Q3 2011 SP1 (v2011.3.1305, Jan. 6, 2012).
Is there any known issues in doing this upgrade? I need to figure out if it's worth upgrading to the latest controls or not.

thank you
