Try setting these properties:

this.gridGroupingControl1.Appearance.GroupCaptionCell.BackColor = Color.Red; 
this.gridGroupingControl1.Appearance.GroupCaptionCell.Themed = false; //so back color will ''take''
this.gridGroupingControl1.Appearance.GroupCaptionCell.Font.Bold = true;
this.gridGroupingControl1.ChildGroupOptions.CaptionText = "{CategoryCaption}={Category}";

See the class reference help on CaptionText to see the tokens you can used with this property.

But when user clicks on one group caption row, I want to change backgroud color to say blue. where can I handle this?

Try handling the QueryCellStyleInfo event. There if the item being drawn is a group caption and the item is th ecurrent item, then set it blue.

private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
	if(e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionCell
		&& e.TableCellIdentity.Table.CurrentElement == e.TableCellIdentity.DisplayElement)
	{
		e.Style.BackColor = Color.Blue;
		e.Style.Themed = false;
	}
}

Hi,
Handling that event as well as the previous settings both does not reflect. Do you think I need to check with versions/any other settings?

I don''t know. Those setting seem to affect things in this sample using version 3.3.

Does this sample not work for you? What are you doing differently?

Hi Clay,
Sorry for late reply.

The sample you sent is working fine. But my grid doesn''t show the changes.

I have set so many properties and handled many events. I am not sure which property/event is stopping this new things. but I have never worked with gridGroupingControl1.Appearence object of GroupCaptionCell. So trying to figure out whatz going on..can you plz help me out?

I do not understand. How would you like me to help you?

Can you upload a sample project whose behavior you want modifed in some way and explain what you want done to it?

[Badri Rajani Kanth]

I mean, I just want to know if any other properties/events can have effect on Appearance object of GroupCaptionCell.

There are many events that might prevent appearance properties from being seen.

Events like TableControlPrepareViewStyleInfo and QueryCellStyleInfo can affect the look of every cell in the grid. Other events like TableControlDrawCell or TableControlCellDrawn or any other events having to do with drawing the cell might affect this.

After you set the property, if you check it immediately, is it set properly? If you later check it in your code, has it been reset somehow? If so, you can try steepingthroug the code trying to see what is resetting the properties.

Hi Clay,
Thank You!

I could figure out the problem and fixed it. Now I am trying to change the current groupcaption display. When I click on any groupcaption cell, QueryCellStyleInfo is not being called. Other events like Click are not giving me the cell type(GroupCaptionCell) and style. Any idea?

Put a Console.WriteLine(DateTime.Now); at the top of your QueryCellStyleInfo code. Then run your code in debug with the ooutput window visible. I think you should see QueryCellStyleInfo being hit when you click a caption. I think it does get hit in the sample posted above.

In the other events, if you add a Console.WriteLine(e.TableControl.GetTableCellViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).TableCellIdentity.TableCellType), what do you see when you click a caption?

Hi,
I am using the below given code in _TableControlCellClick event. The code is exceuted, cell type identified correctly, but display format is not changed. I think these may not be the right one. Plz check once.

if( e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).TableCellIdentity.TableCellType
== GridTableCellType.GroupCaptionCell)
{
Debug.WriteLine("Group Caption Clicked start");
string str1 = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).TableCellIdentity.TableCellType.ToString();
Debug.WriteLine(str1);
Debug.WriteLine("Group Caption Clicked end");

e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).BackColor = Color.Blue;
e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).TextColor = Color.White;
e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).Themed = false; //so back color will ''''take''''
e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).Font.Bold = true;
e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex).Borders.Bottom =
new Syncfusion.Windows.Forms.Grid.GridBorder(Syncfusion.Windows.Forms.Grid.GridBorderStyle.Solid,
System.Drawing.SystemColors.Highlight, Syncfusion.Windows.Forms.Grid.GridBorderWeight.Thick);
}

Is "e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex)" giving me a read-only cell?
