Hi Alexander,
To host ComboBoxes within the ComboBoxDropDown''s PopupContainer you would have set the parent child relationship between the popups as shown below :
// Setup the parent-child relationship between the
// comboboxes'' popup and the ComboBoxDropDown''s PopupContainer
private void comboBoxBase1_DropDown(object sender, System.EventArgs e)
{ this.comboBoxBase1.PopupContainer.PopupParent = this.comboDropDown1.PopupContainer;
this.comboDropDown1.PopupContainer.CurrentPopupChild = this.comboBoxBase1.PopupContainer;
}
Please refer to the
test sample attached that illustrates how you could host ComboBoxes with a ComboDropDown''s Popup. Let me know if you need further assistance. We appreciate your interest in Syncfusion.
