_TabClick event

Hi
I have three tabs (tab1, tab2, and tab3). When I click on tab2, _TabClick event is fired, which is ok.
The problem is how can I fire this event when I click tab2 again?

Thanks
Brew

Change bar's color on client mouse over

Hi,

I couldn't find any help on this. I was wondering if there's a client-side event I can use that will change the bar's color in a Bar chart on client mouse over. Thanks.

Method does not have an implementation after upgrading to 2010.2.713.35

Hello Telerik
I seem to be having a problem with a ListView control after upgrading from 2010.1.309 to 2010.2.713. The following error occurs when attempting to load a page with a ListView on it:

Error Message:

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Method 'get_ProductListViewControl' in type 'Overlord.Product.Views.Search' from assembly 'Product.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Other telerik controls like the RadMenu, RadGrids etc all seem to work fine. Just the ListView is not working properly.

I also have a support ticket open for a production problem we are having with our ListView causing a timeout when paging or sorting. We thought that upgrading to 2010.2.713 might solve the problem, but now we have two problems!

Any help would be greatly appreciated.

The HTML markup for the listview is below. Note that everything was working OK before the upgrade.

RadGrid Row Select not working

Hi all:

I have a web project I just porrted to VS 2010 and the "Q12010 NET40" RadControls. Now for some reason row selection in the grids, which was working fine in the project, has stopped working. I have pasted the code for the grid below, and I did not make any changes to the grid code in teh new project...

Can anyone offer any suggestions?

<telerik:RadGrid runat="server" AllowPaging="True" PageSize="15" ID="grdFilteredHotels" OnNeedDataSource="grdFilteredHotels_NeedDataSource"
Width="1020px" Height="365px" OnRowDrop="grdFilteredHotels_RowDrop" AllowMultiRowSelection="true" AllowSorting="True" BackColor="White"
Style="z-index: 103; left: 0px; position: absolute; top: 27px">
<PagerStyle Mode="NumericPages"></PagerStyle>
<MasterTableView DataKeyNames="Hotel" Width="100%" CellSpacing="-1">
</MasterTableView>
              <ClientSettings AllowRowsDragDrop="True">
                <Selecting AllowRowSelect="True" />
                <ClientEvents OnRowDropping="onRowDropping" />

Urgent: IE Progress bar issue: launching RadWindow from RAD Grid

Hi,

Please treat this as high priority!

When we launch a RadWindow from inside a RadGrid Cell click event, RadWindow shows but after content loading is complete, the IE Progress bar (in the main window) still shows .. like as if the response still is not complete...

Are you guys aware of this issue? Any help would be great.

Hi,

We've almost similar issue , the IE Status bar never stops the progress bar...
This happens (only) when we launch a RadWindow from inside a RadGrid Row or Cell click event.

The content of the Radwindow is shown and then the IE progress bar starts displaying the bar and increasing...
the IE status bar stops when we close the RadWindow.

Can you help to fix this issue?

Update: If we set this property ShowContentDuringLoad = true, the the IE progress bar shows only for the very first click, any subsequent click, the Status bar goes away! We also use ReloadOnShow=true.

Thanks,

Gopi

Rebind RadGrid in parentwindow from RadWindow

I have a main page with a radgrid. In that page is a button that opens up a RadWindow where the user can make some changes that will affect the radgrid. The user hits 'save and close' and I process those changes in the codebehind and then I close the radwindow. Right before closing the radwindow, I'd like to rebind the radgrid that's in the main page.

Is that possible? I'm able to close the radwindow, but not rebind at the moment. That's what I'm missing.
