How to show/set Empty data

[ALEX]

Hi Expert,

            I follow this Combo Example. My problem is user don't key in field. When i show/reload a form, combox is always show first row. Actuall it should be show "Empty Message" in combo box. I search a forum, but i can't find it. :(.

           I set _raddlDelivery.SelectedIndex = -1; But also doesn't work. Kindly, please advice to me.

Hello ALEX,

In order to show empty message in combo box,  set AllowCustomText property of RadComboBox as true.

ASPX:

<telerik:RadComboBox ID="Combo" runat="server"  AllowCustomText="true"
EmptyMessage="Choose a Product">

Thanks,
Princy.

Hi ALEX,

You could aslo set an empty message from the code behind. Please take a look at the following help article as it explains how this can be achieved: Using the EmptyMessage Property.

Hi Princy and Admin,

             I follow your instruction. Stay does not work.

Princy Method.
          I set

<telerik:RadComboBox ID="Combo" runat="server"  AllowCustomText="true"
EmptyMessage="Choose a Product">

           After that

if (Convert.ToString(_order.Delivery) == null || Convert.ToString(_order.Delivery) == "")
             _raddlDelivery.SelectedIndex = -1;//Does not work
            _raddlDelivery.SelectedValue = ""; //Does not work
else
                _raddlDelivery.SelectedValue = Convert.ToString(_order.Delivery);

        If i selected "2W" record, after that i change another record without "Code", it show previous record.

Admin method,

if (Convert.ToString(_order.Delivery) == null || Convert.ToString(_order.Delivery) == "")
       _raddlDelivery.EmptyMessage = "Hello";
else
       _raddlDelivery.SelectedValue = Convert.ToString(_order.Delivery);

           If i selected 2W previous record, after that i change another record without "Code", it show previous record. But when i refresh page, it show "Hello". :(

           I need to set codebehind. I only bind one time, it also does not work. Kindly, please help to me.

Hello ALEX,

I have attached a sample project demostrating a working Empty message for two RadComboBox controls - one binded to a sql datasource (using load on demand) and a second using an xml file. For the xml binded combobox, the empty message is set from code behind, however, you need to set AllowCustomText property as well, so the empty message is displayed.  I hope this is what you need. Please let me know how it goes.
