Ragrid not updating properly

I have updated a cell text in my Radgrid by
1. finding out the selected row and then the particular cell
2. setting the text property of cell to some new value

RadGrid1.SelectedItems[0].Cells[RadGrid1.SelectedItems[0].Cells.Count - 1].Text = tbxEditRowWghtg.Text +

" %";

the problem is the new value only gets displayed when i select another row or when a postback is fired

how do i make it display the new value after closing my popup form?

note that i purposefully didn't use the automatic update command in radgrid for a reason... so what I have done is I've allowed row click selection and then i open a modalpopup form to edit/enter new values to my grid.

Rad Window 2010 Q1 in Firefox 3.6.8 Bug

Hi,

I'm wondering if anyone has been experiencing the issue we are getting since upgrading one of our projects to 2010 Q1.

Since we have upgraded we have found all our rad windows in Firefox 3.6.8 have a white background around them. (see screenshots attached)

This only occurs in FireFox all other major browsers work with no problems. I've tried removing all stylesheets from my template while trying to debug the issue and with no style sheets on the page it still shows the white background.

Has anyone else experience this? and does anyone have any suggestions what could be causing this to occur?

Thanks in advance

Chris

LinqDataSource+RadGrid+server side caching issue

I used example from http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultcs.aspx to cache a data. I added just OrderBy="Name" to LinqDataSort. When ASP.NET form is opened first time everything is good but after paging the sort order is not right. As I understand the issue Linq does OrderBy just when querying data from the database. How to resolve this issue? I have to keep the column Name sorted all time.

<asp:LinqDataSource ID="LinqIdDataSource" runat="server" AutoPage="false"

TableName="V_ID_Dailies" Select="new (ID, Name)"

ContextTypeName="IdLookupDataContext"

OrderBy="Name" OnContextCreating="LinqIdDataSource_ContextCreating"

OnSelected="LinqIdDataSource_Selected" OnSelecting="LinqIdDataSource_Selecting">

</asp:LinqDataSource>

Header Gridlines are overlapping (IE7)

My RadGrids have static headers and i am freezing the first 2 columns.
In Firefox and IE8, the radgrids are very smooth in their scrolling and everything is rendering excellently.
When I switch to IE7 compatibility mode, (or other coworkers view the site in old IE7), the header grid lines are overlapping on top of each other.

I can post my code if you all need to see it, but perhaps this is a simple fix that I am just not getting...

screen shots attached

thanks for any help!

Expand / collapse image size

I have a need to display a hierarchical grid on a touch-screen. The customer is requesting that the size of the buttons be larger for this purpose. I have tried overriding the image size using the following CSS override:

div.RadGrid .rgExpand,

div.RadGrid .rgCollapse

{

height:32px;

width:32px;

}

which works, however the image is located on the top left corner. It would be nicer if it were centered. Is there a better way of accomplishing this? if not is there a way to center the image?

Thanks, Steve
