Multicolumn radcombo box select one

[Mac P]

Hello

How do i insert "Select One" in radcombo that have multiple column
something like http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multicolumncombo/defaultcs.aspx

When i add radcombo item than it doesnt display in the drop downlist. It display "Blank item". when i select that blank item it display select one in the combo box.

Ideally i want user to see "select one" in rad combo when loaded for the first time.

Hello Mac,

One suggestion would be setting the AllowCustomText and EmptyMessage property of RadComboBox like below.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server"  AllowCustomText="True" EmptyMessage="Select One" >
  . . . . . . . . .
</telerik:RadComboBox>

Thanks,
Princy.

Thanks Princy for your response.
Unfortunately it doesnt work for my case. I cannot have AllowCustomText to true.

Hello Mac,

In order to achieve this set AllowCustomText as true and add the following client code, which does not allow user to type something in combo.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server"  AllowCustomText="True" EmptyMessage="Select One" OnClientLoad="OnClientLoad" >
  . . . . . . . . .
</telerik:RadComboBox>

Java Script:

<script type="text/javascript">
    function OnClientLoad(sender, args) {
        var combo = sender;
        var input = combo.get_inputDomElement();
        input.readOnly = true;
      }
 </script>

Thanks,
Princy.

I am also facing same problem. I can see the text but when I press dropdown button I can't see text inside combobox.

Hi Damodar,

You should call DataBind() on this Item after you add it to the RadComboBox so that the Template applies. In this way it will show the Template contents in the drop down, when the latter is opened.

Hi Simon,
Thanks for reply,
I have called DataBind() but I cant see that item inside the Combobox.            
            RadComboBoxItem item = new RadComboBoxItem();
            item.Text = row.Departing.ToString();
            item.Value = row.Departing.ToString();
            RadCBDeparting.Items.Add(item);
            RadCBDeparting.DataBind();
            RadCBDeparting.SelectedValue = row.Departing.ToString();            
            
I have 3 columns in the RadComboBox (in design) but I am setting only one value when loading 
Does it make any differnce? Do I have to specify which Item it should assign to? If yes, how to?
<HeaderTemplate>
<table cellspacing="0" cellpadding="0">
    <tr>
        <td style="width:80px">Port Code</td>
         <td style="width:210px">Port Name</td>
         <td style="width:210px">Market Name</td>
    </tr>
</table>
</HeaderTemplate>
<ItemTemplate>
    <table cellspacing="0" cellpadding="0">
    <tr>
        <td style="width:100px">
            <%# DataBinder.Eval(Container.DataItem, "Port_Code") %>
        </td>     
        <td style="width:240px">
            <%# DataBinder.Eval(Container.DataItem, "Port_Name") %>
         </td>
         <td style="width:260px">
             <%# DataBinder.Eval(Container.DataItem, "Market_Name") %>
          </td>                                   
   </tr>
</table>
</ItemTemplate>

Hi Mac P,

Please take a look at the last section of this help article where inserting a default item in a templated RadComboBox is explained.
Additionally I prepared a sample page for you - please find it attached.
