C# Errors in ASP.NET

Question

Server Error in '/asppub' Application. Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.mis3200_unit4_ringu4pos_aspx' does not contain a definition for 'rblSnacks_SelectedIndexChanged' and no extension method 'rblSnacks_SelectedIndexChanged' accepting a first argument of type 'ASP.mis3200_unit4_ringu4pos_aspx' could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 102:                    Would you like any snacks?</td>
Line 103:                <td class="style7">
Line 104:                    <asp:RadioButtonList ID="rblSnacks" runat="server"  
Line 105:                        RepeatDirection="Horizontal" Width="96px" AutoPostBack="True" 
Line 106:                        onselectedindexchanged="rblSnacks_SelectedIndexChanged">

Source File: c:\Users\Ryan\Desktop\asppub\MIS3200\Unit4\RingU4POS.aspx Line: 104

The given error message in my coding class was this:

 Snacks: toggle visiblity based on yes/no selection:  -2

The list of snacks should only be visible when somebody selects Yes (otherwise, it should be invisible). You needed to double-click the RadioButtonList to create a method which had functionality to toggle the visibility property of the CheckBoxList. For this method to work, you must enable AutoPostBack for the RadioButtonList. "

What am I doing wrong? Any help would be appreciated.

You have missed this in server side

protected void rblSnacks_SelectedIndexChanged(object sender, EventArgs e)
{

}

You should define a rblSnacks_SelectedIndexChanged method in a code behind that will handle the SelectedIndexChange event for the radio button. And if you do not need it, you should remove it.

Add this code in your code behind

protected void rblSnacks_SelectedIndexChanged(object sender, EventArgs e)
{
    // some code
}

As the error suggests, you have to have the SelectedIndexChanged in your code behind. So add this code,

protected void rblSnacks_SelectedIndexChanged(object sender, EventArgs e)
{
    //your code;
}
