ComboBox showing the first value

[Avi]

Hi all,

I'm using a ComboBox attached to SqlDataSource.  When the page is first loaded I would like the ComboBox text to be empty.  Only after the user explicitly selects from the list it should be getting a value.

How can I change this behavior?

Hello Avi,

You can do this by setting the AllowCustomText property of RadComboBox to true.

Thanks for the reply.

I set the AllowCustomText  property to true, but it did not to the trick.  It is still giving me the firts value...

What else can I try?

Thanks,
Avi

Hello Avi,

Please find below a sample code snippet that shows the needed approach.

<form runat="server" id="mainForm" method="post" style="width: 100%">
    <asp:ScriptManager ID="ScriptManager" runat="server" />
    <telerik:RadComboBox ID="RadComboBox1" runat="server" AllowCustomText="True" DataSourceID="SqlDataSource1" DataTextField="itemName">
        <CollapseAnimation Duration="200" Type="OutQuint" />
    </telerik:RadComboBox>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TestDBConnectionString3 %>" SelectCommand="SELECT [itemName] FROM [myMenuLinks]"></asp:SqlDataSource>
</form>

If the problem persists, I think it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
