Change total summary row style in GridView

Hello!
I use RadGridView with grouping (with subtotal summary rows) and with total summary row at the end of the gridview.
I need to change text style only in total summary row. I've tried to use ViewCellFormatting event

private void gvProducts_ViewCellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)

{

if (e.CellElement is GridSummaryCellElement)

{

e.CellElement.TextAlignment = ContentAlignment.BottomRight;

e.CellElement.Font = new Font(e.CellElement.Font, FontStyle.Bold);

}

But this code changes text style in each summary row. Could you help me, how can I understand is it a subtotal summary row or the last total summary row? Thank you in advance.

Reproducing the Office2007blue Group Summary Line

Hi!
Sorry, the title should be: Reproducing the Office2007blue Group Row Line.

After upgrading from 2009-Q1 to 2013-Q2, we found out that the ControlDefault Theme (Office2007Blue) for the gridview's "Group Rows" look significantly different, and cannot be simply reproduced with any provided theme in the 2013-Q2 release.

We really liked having the Group Row looking like:
1) The Group Expansion icon in the first column
2) The Group Summary Text
3) A light-blue horizontal line, with a thickness of about 5 pixels, with rounded endpoints, vertically centered in the row, and going to the last column.

Thanks for your help in reproducing this look using 2013-Q2 technology!

Is it possible to make a Tab Flash?

I was curious if it was possible to make a Non-Active tab flash?

For instance, something is added to the grid on a non selected tab. I would like the tab to flash blue and white until the user clicked on it. But i don't want the application to automatically swap tabs.

Thanks!

Schedule Grid - Scrollbar navigation slowness

Hi,

We are using schedule view to display list of appointments in the range of 1 year with 1500 schedules.

We need to show some of the text in the subject as bold. For that, we are using Run control inside appointment template.
This implementation makes scroll navigation very slow.
Pls let me know the solution or any alternate way for implementing this.

Unable to get horizontal scroll bar on child grid

Apologies if this has been covered, but I have exhausted Google searches on this one.

I have a grid with 5 child grids. One of the child grids does proper horizontal scrolling so the user can see all columns with their widths set as they were at designtime. However, the other 4 would try to mash all coluns together to fit, and then upon changing the size of said columns, it would only show what would fit.

Examining all the properties of the 5 templates, I really don't see anything different that would cause this. I even set HorizontalScrollState to AlwaysShow and still no scrollbar.

Also, I need to know how to change the height of the child grid as well. This could be the problem, maybe the scroll bar is there just not visible?

Thanks.

Problem with RadComboBox and SelectedValue

Hi I have a RadComboBox wihich is populated by a datatable. This is fine. I map the id to an id in my main table using SelectedValue. I have a check in CurrentRowChanging event to see if there are pending changes and there always are, It's as if the combobox keeps setting the rowstate as modified, even though the values haven't changed. Any Ideas?

Group by column but don't allow user to change it

I was just about to send a support ticket when I found the solution to a request for the GridView layout that I'd like to share:

The requested layout:
- The grid is grouped by one column by default
- The user can change the sort order of all columns
- The user can't change the grouping of the grid

Solution:
- Add the GroupByExpression for the column in code or through the designer
- RadGridView.EnableGrouping == true (if false, the grouping header is not shown)
- RadGridView.MasterGridViewTemplate.AllowDragToGroup == false (no more columns can be added to the grouping header)
- set the "AllowGroup" property of the column in the grouping header to "false" (the user can't remove the grouping column from the header)

Perhaps someone else finds this useful.

EDIT:
I missed, that the "column button" in the grouping header contains a "X" to remove the group. This Close Button is still enabled and the user can remove the group. Any suggestions?
