RadComboBox Selects a Different Item
DESCRIPTION
The user selects an Item from the drop down.
PROBLEM
Another item gets selected.
CAUSE
Items have identical values. On blur or postback the RadComboBox searches for the first Item with the selected value and selects it.
ASPNET
<telerik:RadComboBox RenderMode="Lightweight" ID="RadComboBox1" runat="server">
<Items>
<telerik:RadComboBoxItem Text="Item 1" Value="1" />
<telerik:RadComboBoxItem Text="Item 2" Value="1" />
<telerik:RadComboBoxItem Text="Item 3" Value="1" />
</Items>
</telerik:RadComboBox>
The same behavior will manifest when the items are having the same Text and no Values:
ASPNET
<telerik:RadComboBox RenderMode="Lightweight" ID="RadComboBox1" runat="server">
<Items>
<telerik:RadComboBoxItem Text="Item" />
<telerik:RadComboBoxItem Text="Item" />
<telerik:RadComboBoxItem Text="Item" />
</Items>
</telerik:RadComboBox>
RESOLUTION
Make sure that all Items have unique values.
