Change default HTML output for a tool

I am trying to change the default HTML output of the table tool so that whenever it is used the HTML inserted has the width automatically set to 100% and the margin and padding set to 0. I've tried using "OnClientCommandExecuting" but I'm not sure I'm going down the right path. Can this be achieved?

RadGrid with RadFilter Group Summaries

I have a large dataset that I would like to be able to group in order to show a "summary" view. Because the dataset is very large, I have paging enabled.

I'm having trouble showing multiple collapsed groups on one page. Here is an example of one page: <groupbyproject.jpg >

I would like to see something like this: <groupbyproject_all.jpg>

Thank you

Very Strange error when returning from postback

Hi

I dont know If this has been asked before. Did not see the same occurance.

I have a RadGrid that is populated with the NeedDataSource property which gets a list of Items from the Database. These records are all Identical at first except for there ID.

The Grid works with Item GridTemplateColumns and GridBoundColumns.
Most of the Columns have Dropdownboxes for editing.
One of the dropdownboxes calls a Method from Serverside to determine if Input validation on another control must take place.

Here is the problem All the records work perfectly eccept for the 2nd record.
When ever I change the value I can no longer Change the field that is being validated and no postbacks can be preformed because of the validator.

Any Advice wood be great or a posible cause for why only the 2nd record has this problem.

Below is the Grid

Adding A Webservice Enabled Tooltip To RadComboBox Item

Hello,

I sucessfully added a radtooltip to a RadList control by using the ItemDataBound event using this code in the page:

    <telerik:RadToolTipManager ID="radToolTipManager1" runat="server" HideEvent="LeaveTargetAndToolTip"
    Width="250" Height="100" RelativeTo="Element" Position="MiddleRight" ShowDelay="500" >
    <WebServiceSettings Method="GetToolTipData" Path="~/Services/ToolTipWebService.asmx" />
    </telerik:RadToolTipManager>

And this in the code behind

 void RadListBoxSource_ItemDataBound(object sender, RadListBoxItemEventArgs e)
{
    if (e.Item is RadListBoxItem)
        {
            this.radToolTipManager1.TargetControls.Add(e.Item.ClientID, (e.Item as RadListBoxItem).Value, true);
        } 
}

The value is an ID that can be used to return a list from the webservice (in this case a list of Departments the hovered over person works for).

I tried to adapt this code for a RadComboBox on the same page, but no ToolTip is shown.

void ddPerson_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
{
   if (e.Item is RadComboBoxItem)
   {
      this.radToolTipManager1.TargetControls.Add(e.Item.ClientID, (e.Item as RadComboBoxItem).Value, true);
   }
}

Is there a step that I am missing? The ClientID for the item when I add a breakpoint is something like "i0" which doesn't seem long enough.

Thank you for your help

Chrome-specific error using Mac 21.0.1180.57

Hi,

We are running into a repeatable issue wherein Chrome and only Chrome dies with the following error "Uncaught SyntaxError: Unexpected Token. The error seems to be random. It absolutely kills everything and you need to do a complete reload of the screen.

Sometimes associated with a RadComboBox, other times, the RadProgress area. In googling this, there were suggestions regarding eliminating possible hidden garbage characters in the .aspx.

In VS 2008, we copied out of VS into notepad and back in and also tried the Advanced - > Delete Horizontal White space option in VS 2008, but the problem persists. It presents itself in complex layouts where a RadMenu, ComboBox, Grid, MultiPage, Editor and Tab interface are provided. The screen in question does not use RadAjaxManager.

Any thoughts on how to diagnose and resolve this would be most welcome. This does not occur in Firefox or IE 9.
