Get unformatted value of RadGridItem Cell

I am using this code in the ItemDataBound function of my radGrid in order to set the tooltip to the text of the cell:

if(e.Item is GridDataItem)

{

foreach(TableCell cell in e.Item.Cells)

{

cell.ToolTip = cell.Text;

}

I am formatting the column to hide all decimals for space reasons, but I am also using filtering. It is possible that one filters for say where column xyz >= 50 and a row showing 50 will not show up because the value is really 49.6.
I would like the tooltip to shop 49.6, not 50.

Is this possible?

Thank you for any expert advice.

OnCollapsed event

Hello,

I am working with the RADGrid and need to catch the OnCollapsed event when a group is collapsed.

I've set the following properties in the grid

   function GroupCollapsed(sender, args) {
   alert('colapsed');
   }

</ClientSettings>

When I click a row I'm seeing the GroupCollapsed function get executed however it does not get executed when I collapse an expanded group, as I would expect.

I'm pretty sure this is just some minor detail I'm missing but I haven't been able to find it yet.

Any input is appreciated.

Thanks in advance,
jeff bryant

Change height RadTab

Hi I have tried for a while to create a tabstrip and modify the height of the tabs and the fonts (make them much bigger).
I have tried many different ways but never managed to achieve it. (I mean it looks very ugly - backcolor or bgimage just not right)
Is it possible for you guys to give me a little example on how to do it?

Regards.

Radgrid onselectedindexchanged for 2 buttons

I have 2 buttons (GridButtonColumn) on the radgrid doing different action, the first one

<telerik:GridButtonColumn CommandName="Select" DataTextField="TagID" ButtonType="ImageButton"ImageUrl="images/go.gif" UniqueName="colgo" ></telerik:GridButtonColumn>

<telerik:GridButtonColumn CommandName="Select" DataTextField="TagID2" ButtonType="ImageButton"ImageUrl="images/go2.gif" UniqueName="colgo2" ></telerik:GridButtonColumn>

By using onselectedindexchanged

="rgSearch_SelectedIndexChanged", which allows me to put code behind under

protected void rgSearch_SelectedIndexChanged(object sender, EventArgs e)

{
}

How can I idendify under rgSearch_SelectedIndexChanged, the sender is from which button, in order to put different action code in.

Thanks,
Jessie

RadEditor MOSS 2007 removes style

Hello,

We have an issue with RadEditor MOSS 2007 removing a style attribute. The original HTML in a SharePoint Wiki item contains the following:

<TD class=detailsHeader background=/PublishingImages/sectiontitle_03.gif>

When that page is ediied with RadEditor activated, that code is tranformed to:

<td style="background-image: url(/publishingimages/sectiontitle_03.gif);" class="detailsHeader">

When the page is saved, the style attribute is removed.

Can you explain why this happens, or if there is a way to prevent this behavior?

Thank you,
Craig Smith

Response.Write error

Hi all,

in RadAjaxManager1_AjaxRequest event I select data from database into reader, then if reader is Nothing i want to prompt alert
Response.Write("<script>alert('There is no Data to show');</script>") .

when I run alert didn't prompt, just got as below

...

Error: Sys.WebForms.PageRequestmanagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the reponse is modified by calls to Reponse. Write(), reponse filters, httpModules, orserver trace is enabled.
Detail: Error parsing near '<script> alert(' .

How can I solve this please...

Thanks and best regards
