Try

protected void MaterialNameChk_CheckedChanged(object sender, EventArgs e)
 {
      if (sender != null)
      {
        CheckBox checkbox = (CheckBox)sender;    
    	if(checkbox != null)
    	{
        Label idlbl = checkbox.Parent.FindControl("MaterialId") as Label;

    	}
   }
}

Hi JoCodes,
I guess it will work on Parent.Parent , since the check box parent is Div and div's Parent is the datalist item...
Label idlbl = checkbox.Parent.Parent.FindControl("MaterialId") as Label;
just check once...

Thanks Karthik . I just cross checked the same code with checkbox.Parent.GetType()and it returns Datalist type with single Parent? If div had runat= server then would have an issue.But really appreciate the point. :)
