Question

I am using C# Visual Studio 2005 and SQL Server 2005.

I have a GridView table which shows a list of data from my SQL Server database.

I establish my connection via PageLoad method. E.g.:

protected void Page_Load(object sender, EventArgs e)
    {
        SqlDataSource1.SelectCommand = "SELECT * FROM [UserTable]";
        SqlDataSource1.DataBind();
    }

---

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1">
    </asp:GridView>

However, I am trying to add a function for my Gridview table:

To enable removal of records from the GridView via checkbox of each row of record and a remove button.

The output I want is a checkbox for each row of data of the Gridview, and a ‘Remove’ button which delete all the records with their checkbox ‘checked’.

May I know how can I approach to the outcome that I want?

Thank you

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1">       
                    <Columns>
                         <asp:TemplateField HeaderText="Name">
                            <ItemTemplate>

                              <asp:CheckBox ID="CheckBox1" OnCheckedChanged="--your events--" runat="server" />
                                 <asp:LinkButton ID="lnkDelete"  runat="server" onclick="lnkDelete_Click"  Text="Delete"
                                 CommandArgument='<%# Eval("id") %>' ></asp:LinkButton>
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
 </asp:GridView>

on lnkDelete_Click event

LinkButton lnk = (LinkButton)sender;
 int stid = Convert.ToInt32(lnk.CommandArgument);

now you have id of table which is primary key and you put your delete code here.
