Hi Telerik Team,

RadCombobox selected text have change after selected and click somewhere on page.
I notice that this happening when items are same value. If value are unique this will not happening.

Please test the following code.
If select "ccc" or "ddd" and click somewhere the selected text will change to "aaa"
If select "222" or "333" and click somewhere the selected text will change to "111"

Hello Avelyn Teh,

As Kalina said the RadComboBox items need to have unique values. If you still want to use the RadComboBoxItems with same values then one option is to use CustomAttributes. You can access this value either from server side or client side. Here is a sample code.

aspx:

<telerik:RadComboBox ID="CboPOL" Runat="server" OnClientBlur="OnClientBlur">

<Items>

<telerik:RadComboBoxItem runat="server" Text="aaa" customValue="First" />

<telerik:RadComboBoxItem runat="server" Text="bbb" customValue="First" />

<telerik:RadComboBoxItem runat="server" Text="ccc" customValue="First" />

<telerik:RadComboBoxItem runat="server" Text="ddd" customValue="First" />

<telerik:RadComboBoxItem runat="server" Text="eee" customValue="First" />

<telerik:RadComboBoxItem runat="server" Text="111" customValue="Second" />

<telerik:RadComboBoxItem runat="server" Text="222" customValue="Second" />

<telerik:RadComboBoxItem runat="server" Text="333" customValue="Second"/>

<telerik:RadComboBoxItem runat="server" Text="abc" customValue="Third" />

<telerik:RadComboBoxItem runat="server" Text="hij" customValue="First" />

</Items>

</telerik:RadComboBox>

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

C#:

protected void Button1_Click(object sender, EventArgs e)

{

string value = CboPOL.SelectedItem.Attributes["customValue"].ToString(); //accessing the custom attribute value

Response.Write(value);

}

Thanks,
Shinu.
