Hi,
    Can anyone let me know how to access the Group Header item of rad grid from client side so that i will be able to change the text of it? I am using rad controls for asp.net ajax.

Please let me know as early as possible bcos it is of high importance.

Thanks,
Preetam.

Hello
In a plain ASP GridView, I was using a "OnRowDataBound" event to dynamically modify columns in a grid depending on the contents of the underlying row. It worked just the way I wanted.. I was trying to change the grid to a RadGrid, and there is no such equivalent event. Is there a way to do perform the same function in the RadGrid?

Thanks
Harold

I am using Charting Q1 2008. I've dragged the chart to the page, set it up and I don't get any errors, but I get a broken image link. Version Q1 doesn't have a RadControls folder to put into the site. The Web config has the handlers in it. As I said there are no errors, but there is no chart either. I can't seem to figure this out.

Hi There,

Is there a way to know wich column was clicked in the OnRowClick event ?

Hello,

I am displaying a datalist with command buttons an images, doing paging with a request to database which selects records composing the displayed page, each paging command triggers a paged_change which read DB and bind the dataList to a SqlDataReader.

I have ajaxifyed the paging control and the datalist in the Page_Load from codebehind, adding ajaxsettings to AjaxManager.
DataList->Pager
DataList->Pager
Pager->Pager
Pager->DataList

I have a strange behavior: each odd request refuses to display the command buttons in the DataListItems.
First display is Ok, pressing PageNext I get a page with DB info but no image for buttons, pressing again PageNext I get a perfect page, etc.
When on firt page I enter in pager page 3, I get a page without images for buttons, the problem is not related to data in pages.

Reading the page generated html, I see that the <img> or <input type="image"> are correctly generated and contain their src attribute with correct path.
Why aren't they displayed ?
They are exactly the same as the ones on the pages correctly displayed ?
I have no error in IE7 on the page after display ?????


Any idea welcome.

I am displaying a RadUpload control with RadTreeView.
When a node gets expanded and clicked on the RadTreeView I am displaying a RadUpload control which allows the user to upload documents and details on the document.

This works okay until the user clicks on another RadTree Node.  The user clicking on a different node is causing a postback.  RadUpload is then attempting to upload nothing (i'm assuming this is what is happening).  I then get an access denied error.

Any work arounds or ideas on how I can handle this situation?

Thanks!

Hi,

The RadFormDecorator set my button size wider than it should be.

To produce it, its very easy.

Just have a page with RadFormDecorator
and
A Button
Set the text of the button as "..."

It is suppose to be very small, but it turns out the RadFormDecorator makes it so big.

Is there a way to fix that ?

Thanks.

hello, I have a column in a radgrid that is a lookup in another table, with allow null. so it is GridDropDownColumn. the problem is while filtering (by its ID), it crashes somewhere in telerik code.

p.s.
We made a custom filter that allows filtering by values of the lookup tables in a combobox, but it crashes in the same spot, when firing the filter event.

some workaround I can think of is bringing say '-2' instead of <null> from database, I never tried it yet though.

easy to reproduce, just bind a grid to a column of type int with allow null.
filter using "equal" -> it will crash.

Hi All,

I have a column inside my grid that hold a drop down list.  On client side or in a Javascript function, anyone know a correct way to make a reference to that drop down list?

This is what I have in my code:

var grid = <%= rgDRFormASPPFCaseInfo.ClientID %>;

var tableView = grid.MasterTableView;

var ID = tableView.GetCellByColumnUniqueName(tableView.Rows[RowIndex],"ID").innerHTML;

var ddlList = tableView.GetCellByColumnUniqueName(tableView.Rows[RowIndex],"Answer");

Please help

Thanks

I use a RadWindow to update a row in my grid.  In the RadWindow I click save and have an event to handle the transaction.  However, the window closes but the parent page with the grid does not rebind/refresh with the new data. 

How do you get it to refresh on a save from a RadWindow?

All I have so far is to close the window.
