How to control which item is selected when the page is first-loaded?

[Nim]

Hello,

I'm building a MVC program.

In the view, I have a combo box:

    <telerik:RadComboBox ID="RadComboBox1" runat="server"
        DataSourceID="EntityDataSource1" DataTextField="data"
        DataValueField="value">
    </telerik:RadComboBox>

I can populate the combo box with a list of options provided by the database (through Entity).

Here is my question.

Say, in some situations, when the page is loaded, I want option 1 to be selected first; then in some other situations, when the page is loaded, I want a different option, say option 3, to be selected.  And say, the situation will depend on a magic number I store in the session.

Is there anyway I can control which option to be selected when a page is loaded (without using ajax call after the page is loaded)?

Also, is there any small example to demonstrate how to control which item to be selected at the beginning, in MVC environment?

Many thanks!

Hello Nim,

If you want a certain item to be selected when the page loads, just called DataBind(0 on the RadComboBox control and then set the SelectedValue to the items you want selected.

I hope that helps.

Hello,

Thank you for the tip.

I may be missing something in the documentation.

I am not sure how to use "DataBind" and "SelectedValue" in the View.

Is there any small example to demonstrate this for MVC program?

Many thanks!

Hello Nim,

You just add a code block. Like so:

<% RadComboBox1.DataBind();
RadComboBox1.SelectedValue = "Some Value"; %>

I hope that helps.

Hi Nim,

Please note that  ASP.NET and ASP.NET MVC are two completely different frameworks.

Because of this we have created a whole new control family called Telerik Extensions for ASP.NET MVC.
I would suggest you use the Telerik ComboBox for ASP.NET MVC control instead of RadComboBox for ASP.NET AJAX.
You can find the key features of the Telerik ComboBox for ASP.NET MVC demonstrated here.
