Hi Santosh,
Thanks for your interest in Syncfusion products.
MultiColumnComboBox has been implemented by combination of two more controls. When we click on outside of the minitool bar, it will be closed. Now I have handled this problem in work around. Please find the following sample link which illustrates “if the row is outside minitoolbar box area the minitoobar is not visible.”
http://www.syncfusion.com/uploads/redirect.aspx?&team=support&file=WindowsFormsApplication2-1514946789.zipThe sample code as follows,
void miniToolBar1_Closing(object sender, ToolStripDropDownClosingEventArgs e)
{
if (this.multiColumnComboBox1.DroppedDown)
{
e.Cancel = true;
}
}
Please let me know if you need further information on this.
Thanks,
Karikalan N
