Change Grid AlphaBlendSelectionColor

[James]

Hi,

I change grid.AlphaBlendSelectionColor to Color.FromArgb(255, SystemColors.Highlight) to make the selection color same as standard windows highlight color. However, the grid selection color still does not look the windows highlight color. It seems like the grid only take opaque at fixed 64. How can I change that? Thank you in advance.

I think you can both items through the PrepareViewStyleInfo event.

private void Form1_Load(object sender, System.EventArgs e)
{
	this.gridControl1.ListBoxSelectionMode = SelectionMode.One;
	this.gridControl1.Model.Options.RefreshCurrentCellBehavior = GridRefreshCurrentCellBehavior.RefreshRow;
}
private void gridControl1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
	if(e.ColIndex > 0 && e.RowIndex == this.gridControl1.CurrentCell.RowIndex)
	{
		e.Style.BackColor = SystemColors.Highlight;
		e.Style.TextColor = Color.White;
	}
}

It works fine except the selected color becomes default AlphaBlendSelectionColor when grid lost focus. How can I control the deactivated row (cell) color?

Thanks!

You can try using CurrentCellMoved to refresh both the old and new row.

private void gridControl1_CurrentCellMoved(object sender, GridCurrentCellMovedEventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	this.gridControl1.RefreshRange(GridRangeInfo.Row(cc.MoveToRowIndex));
	this.gridControl1.RefreshRange(GridRangeInfo.Row(cc.MoveFromRowIndex));
}

It works when moving within the gird. The problem is the selected row's color has changed to default AlphaBlendSelectionColor when the focus is moved to other control in the form.

I myy be missing something, but I do not see this behavior in the attached project when I click on the button to cause the grid to lose focus. Do you?

I changed current row's color as following:
private void gridControl1_PrepareViewStyleInfo(...)
{
// if current row
{
e.Style.BackColor = SystemColors.Highlight;
e.Style.TextColor = Color.White;
}
}

I have grid and other buttons in a form. When I select a row in the grid, the current row's color is changed to system highlight color. Whenever I click a button on the form, the focus is moving away from grid, the slected row's color is changed to AlphaBlendSelectionColor.
Just wondering where the grid does the change and how to to override it to change to system highlight color.

Can you post a sample project showing the problem?

I could not see it in the sample I uploaded. I think I did exactly what you described. Could you see the problem in the sample I uploaded?

Try setting

this.gridControl1.AlphaBlendSelectionColor = Color.FromArgb(1, SystemColors.Highlight);

to see if that affects anything for you.
