  • *****get default focusedcell backcolor

     from:

    http://www.devexpress.com/Support/Center/p/CQ55609.aspx

    Is it possible to determine the default focused cell backcolor at run time if we havent overriden it already.

    Unless I explicitly set the focusedcell backcolor, it shows as zero.
    But I want to know the actual "default" color that will be used so I can apply the same color in another area.

    Is this possible?

    This does not work.
     Following is the immediate output from the following command. As you can see, it returns Color.Empty (view is a gridview object which has not had the focusedcell.backcolor modified)

    ?view.PaintAppearance.FocusedCell.BackColor
    "{Name=0, ARGB=(0, 0, 0, 0)}"
        A: 0
        B: 0
        G: 0
        IsEmpty: true
        IsKnownColor: false
        IsNamedColor: false
        IsSystemColor: false
        Name: "0"
        R: 0 

    Hello Geoffrey,

    Thank you for the sample project. The cause of the problem is that you obtaining colors within the Form's Load method. At this point the Grid's internal structures are not initialized yet. We are using a postponed initialization mechanism in our controls so theirs internal objects are initialized only after the control's handle is created. However, you can force the initialization by calling the GridControl's ForceInitialize method before obtaining colors:

    [C#]

    foreach (Control c in this.Controls)
    {
        if (c is GridControl)
        {
            textBox1.AppendText("Grid:" + c.Name + Environment.NewLine);
            GridControl grid = (GridControl)c;
            grid.ForceInitialize(); ///... <<<<< add this line
            foreach (GridView view in grid.ViewCollection)
            {
                textBox1.AppendText("\tView:" + view.Name + Environment.NewLine);
                foreach (AppearanceObject appearance in view.PaintAppearance)
                {
                    textBox1.AppendText("\t\tAppearance:" + appearance.Name + Environment.NewLine);
                    textBox1.AppendText("\t\t\tBackColour:" + appearance.BackColor.ToString() +
    Environment.NewLine);
                }
            }
        }
    }

    Please try this solution and inform us of your results.

    Thanks,
    Stan.

    gridControl1.ForceInitialize();
                foreach (AppearanceObject appearance in gridView1.PaintAppearance)
                {
                    if (appearance.Name == "FocusedRow")
                    {
                        gridView1.Appearance.FocusedCell.BackColor = appearance.BackColor;
                        break;
                    }
                }
