Changing the Drop-Down Window Direction
ColorPicker > C1ColorPicker Task-Based Help > Changing the Drop-Down Window Direction

By default, when the user clicks the C1ColorPicker control's drop-down arrow at run-time the color picker will appear below the control, and if that is not possible, above the control. However, you can customize where you would like the color picker to appear. For more information about the drop-down arrow direction, see Drop-Down Direction.

At Design Time in Blend

To change the drop-down window direction at run time, complete the following steps:

  1. Click the C1ColorPicker control once to select it.
  2. Navigate to the Properties window and click the C1ColorPicker.DropDownDirection drop-down arrow.
  3. Choose an option, for example ForceAbove.

This will set the C1ColorPicker.DropDownDirection property to the option you chose.

In XAML

For example, change the drop-down window direction add DropDownDirection="ForceAbove" to the <c1:C1ColorPicker> tag so that it appears similar to the following:

XAML
Copy Code
<c1:C1ColorPicker Name="C1ColorPicker1" Margin="296,98,273,0" Height="45" VerticalAlignment="Top" DropDownDirection="ForceAbove"/>

 

In Code

For example, to change the drop-down window direction, add the following code to your project:

Visual Basic
Copy Code
Me.C1ColorPicker1.DropDownDirection = DropDownDirection.ForceAbove

C#
Copy Code
this.c1ColorPicker1.DropDownDirection = DropDownDirection.ForceAbove;

 

This will set the DropDownDirection property to ForceAbove.

Run the application and observe:

When you click the C1ColorPicker control's drop-down arrow, the drop down window will appear above the control:
