How to Customize the Color Cells of the UserColors Group

4 Feb 20252 minutes to read

Color cells of the UserGroup panel in a ColorUIControl, can be customized using the below code. We can use UserColors and UserCustomColor for this purpose.

// For example assume you have a ColorUIControl colorUIControl1.
for( int i = 0 ; i < this.colorUIControl1.UserColors.Count; i ++ )
{
    this.colorUIControl1.UserColors[ i ] = Color.FromArgb( 0, 0, i * 5 );
}
for( int i = 0 ; i < this.colorUIControl1.UserCustomColors.Count; i ++ )
{
    this.colorUIControl1.UserCustomColors[ i ] = Color.FromArgb( i * 15, 0, 0 );
}
this.colorUIControl1.SelectedColorGroup = Syncfusion.Windows.Forms.ColorUISelectedGroup.UserColors;

// Resize of ColorCells can be done using property UserColorsStretchOnResize.
this.colorUIControl1.UserColorsStretchOnResize = true;
Dim i As Integer
For  i = 0  To  Me.colorUIControl1.UserColors.Count- 1  Step  i  + 1
Me.colorUIControl1.UserColors( i ) = Color.FromArgb(0, 0, i * 5)
Next
Dim i As Integer
For  i = 0  To  Me.colorUIControl1.UserCustomColors.Count- 1  Step  i  + 1
Me.colorUIControl1.UserCustomColors( i ) = Color.FromArgb(i * 15, 0, 0)
Next
Me.colorUIControl1.SelectedColorGroup = Syncfusion.Windows.Forms.ColorUISelectedGroup.UserColors

' Resize of ColorCells can be done using property UserColorsStretchOnResize.
Me.colorUIControl1.UserColorsStretchOnResize = True

NOTE

UserGroups should be selected in ColorGroups property to effect the above settings.
