Hi Mohamed,

Please have a look at our online example on Validation. Could you reproduce the same issue with it?

Also,could you please open a support ticket and send us a simple running project to test it locally? We will review it and provide you with a solution or more specific instructions.

Hello Mohamed,

Please try the following javascript:

<script type="text/javascript">  
 
function pageLoad()  
{  
    var combo =$find("RadComboBox1");  
    if(combo.get_text()!=" - Select a City - ")  
        combo.findItemByText(combo.get_text()).select();  
}  
</script> 

This should helps.

Hi,

We are experiencing same issue.

We have a radcombobox which has requiredfieldvalidator associated with it. For the first time it validates the required value, but if we select some value from dropdown and then select the "--Select--" back in the dropdown, its not validated by requiredfieldvalidator. We have tried InitalValue of requiredfieldvalidator with both "Text" and "Value" of 1st item in the dropdown (1st item is --select--).

Please help.

Hi

Please check the following code I tried which works fine at my end.

ASPX:
<telerik:RadComboBox ID="RadComboBox1" runat="server">
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="Select" />
        <telerik:RadComboBoxItem runat="server" Text="Item 1" />
        <telerik:RadComboBoxItem runat="server" Text="Item 2" />
        <telerik:RadComboBoxItem runat="server" Text="Item 3" />
        <telerik:RadComboBoxItem runat="server" Text="Item 4" />
    </Items>
</telerik:RadComboBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadComboBox1"
    InitialValue="Select" ForeColor="Red">*
</asp:RequiredFieldValidator>

Thanks,
Shinu.

In the demo validation passes if you just type any text into product and region comboboxes. I'm using custom validator for comboxboxes with custom text allowed and check if both selected value and text are not empty. Is there's a better way round?
