ASP.NET controls in Eval if else statement?

Question

I want to show checkbox or radiobutton according to typeId.

<%# (Eval("TypeId").ToString() == "1") ? "CheckBox" : "RadioButton"%>
<asp:CheckBox ID="CheckBox" runat="server" Text='<%#Eval("OptionName")%>' />
<asp:RadioButton ID="RadioButton" runat="server" Text='<%#Eval("OptionName")%>' />

If typeId == 1 I want to show checkbox that is in my code line else I want to show radio button. How can I do this.

Thanks.

This is too difficult for me. Because I used 3 nested repeater and this code in third level repeater :) — AliRıza Adıyahşi

You can use the Visible property:

<asp:CheckBox ID="CheckBox" runat="server" 
    Text='<%#Eval("OptionName")%>' 
    Visible='<%# Eval("TypeId").ToString() == "1" %>'
/>
<asp:RadioButton ID="RadioButton" runat="server" 
    Text='<%#Eval("OptionName")%>' 
    Visible='<%# Eval("TypeId").ToString() != "1" %>'
/>

Add two bool properties to your datasource called, for example, ShowCheckBox and ShowRadioButton

public bool ShowCheckBox
{
    get
    {
         return TypeId.ToString() == "1";
    }
}

and use these to data bind to the Visible properties

<asp:CheckBox ID="CheckBox" runat="server" Visible='<%#Eval("ShowCheckBox")%>' />

Try this:

<asp:CheckBox ID="CheckBox" runat="server" Visible="<%# (Eval("TypeId").ToString() == "1") ? True : False %>" Text='<%#Eval("OptionName")%>' />

In the Repeater.ItemDatabound event, add the appropriate control there.
