ComboBox question

[Nicola]

Hi,

I was wondering if anyone has come across a way to change the background color of a combobox cell but not the button color. I am setting my cells background color to black but then the combobox button also changes to black. Any suggestions would be appreciated

Thanks

I do not see this behavior. Dropping a gridcontrol on a form and adding this form load, the combo button still shows gray for me.

private void Form2_Load(object sender, System.EventArgs e)
{
	this.gridControl1[2,2].CellType = "ComboBox";
	this.gridControl1[2,2].BackColor = Color.Black;
}

Are you doing something different? Can you post a sample or show code where you are setting up the cell?

I am setting the background color in the PrepareViewStyleInfo function. Could this be causing my problem?

I added a PrepareViewStyleInfo event handler and set the e.Style.BackColor there when the cell was 2,2 and still could not see the problem.

Do you really see a black button, or is the button missing (and this is reason the whole cell is black). If it is the latter, you might make sure you are setting e.Style.CellType = "ComboBox" in this case.

I really see a black button. I can click on it and my dropdown list appears.

Can you reproduce this in any of our samples, say the grid\samples\CellTypes\ComboBoxes? Or can you post a sample showing the problem?

Also, do you have XP-Themes enabled?

I figured out what I was doing wrong. I had intercepted the DrawCellButtonBackground event. And didn''t realize this is what was causing the problem.

Thanks for all your help!
