The RadColorPickerControl does not offer the functionality you describe. What you can do is the following:
- Set the Text property of the TextBox to the SelectedColor of the RadColorPicker when you create the TextBox.
- On the client, handle the mousedown event of the TextBox and use the showPalette client method of the RadColorPicker to open the palette.
- Use the ClientColorChange event of the RadColorPicker to update the text of the TextBox when you select a different color.
Please refer to our online demos
for a simple example how you can use the showPalette method and the ClientColorChange event of the RadColorPicker.
