I am using 2 UltraCombos which make multi selection.
The selection of first ultracombo affect the items of the second ultracombo.
At the AfterCloseUp eventhandler of the firest ultracombo, I change the items of the second ulracombo.
However, after executing the eventhandler, the unknown exception occured.
This is the code.
private void ultraCombo1_AfterCloseUp(object sender, EventArgs e) {
ultraCombo2.DataSource = SharedInfo.SelectedItems;
for (int i = 0; i < ultraCombo2.Rows.Count; i++) { ultraCombo2.Rows[i].Cells["Selected"].Value = true; }
}
The exception is,

Hi Mike,
Thanks for your help.
After installing the service release, the exception does not occur any more.
Hi,
What do I have to do with your sample in order to get the exception to occur. I ran the sample, dropped down the first combo, selected some values, and then closed the combo, but I got no exceptions - everything worked just fine.
Perhaps you just need to get the latest service release.

I attached a sample project that shows similar exception.
When I change the datasource of UltraCombo which has selected value,
the exception occur.

Exception message is...
"System. ArgumentOutOfRange Exception. Parameter Name : iteIndex..............:
Well, that further reinforces my theory. The control is trying to resolve the appearance of an item that no longer exists. I would think that setting the control's Value to null before you clear and repopulate the list should fix that. But if that's not working, then I am out of ideas.
Can you post a small sample project which demonstrates the exception so we can take a look at it?
I set the value property of the ultraComb2 as you said, but the exception is still thrown.
I don'know why it happens.
Please let me know how to resolve this.
Thanks,
