How can I change select all the items on selecting the first item in the UltraComboBoxEditor:
Hello,
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;
I am checking about the progress of this issue. Please let me know If you need any further assistance on this.
