Hello,
I am checking about the progress of this issue. Please let me know If you need any further assistance on this.
Please try the following code sample and let me know if it helps:
void ultraComboEditor1_ValueChanged(object sender, EventArgs e)
{
if (ultraComboEditor1.Text.Contains(ultraComboEditor1.Items[0].DataValue.ToString()))
foreach (ValueListItem item in ultraComboEditor1.Items)
item.CheckState = CheckState.Checked;
}
else
item.CheckState = CheckState.Unchecked;
