Stop comboBox's selectedIndexChanged event from firing when the form loads
If you want to react only when the user change the selected item in the combo box, then it is better to subscribe to SelectionChangeCommitted.
You can simply unbind the SelectedIndexChanged
event, call your fill
function and bind the SelectedIndexChanged
event again. Unfortunately, this doesn't work with a grid.
For example:
this.cmb.SelectionChanged -= new System.EventHandler(this.cmb_SelectionChanged);
cmb.fill(); //Your function
this.cmb.SelectionChanged += new System.EventHandler(this.cmb_SelectionChanged);
Be sure to set the DataSource
property in your onload()
function after assigning the ValueMember
and Datamember
properties.
This will help you to solve your problem!
