1 min read

In ComboDropdown control, it is possible to load custom control as its DropDown control.

For example:

User may like to create ColorPickerComboBox that can display ColorPickerAdv as its Dropdown control and update its selection color as its TextBox Back color.

The following code example demonstrates the same.

 
//To assign the drop dropdown control
this.comboDropDown1.PopupControl = this.colorUIControl1;
//To specify the backcolor of the ComboDropDown
this.comboDropDown1.BackColor = this.colorUIControl1.SelectedColor;
//To set the backcolor of the text box used inside the ComboDropDown
this.comboDropDown1.TextBox.BackColor = this.colorUIControl1.SelectedColor;
//To specify whether the backcolor needs to be applied.
this.comboDropDown1.UseBackColor = true;

 
'To assign the drop dropdown control
Me.comboDropDown1.PopupControl = Me.colorUIControl1
'To specify the backcolor of the ComboDropDown
Me.comboDropDown1.BackColor = Me.colorUIControl1.SelectedColor
'To set the backcolor of the text box used inside the ComboDropDown
Me.comboDropDown1.TextBox.BackColor = Me.colorUIControl1.SelectedColor
'To specify whether the backcolor needs to be applied.
Me.comboDropDown1.UseBackColor = True
