GridView with CheckBox for Deleteing the checked Items..

Take This Items In webForms

- One gridView

- One Button for Delete all the Checked CheckBox..

Lets see one by one how can we put checkbox inside GridView

[asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"]                       
   [asp:BoundField DataField="roll_no" HeaderText="Roll No" /]
   [asp:BoundField DataField="s_name" HeaderText="Student Name" /]
   [asp:BoundField DataField="class" HeaderText="Class" /]

In your .cs file in the class level write this line of code
