I have a gridview that displays data coming from an SQL data source (stored procedure) and I want to add a checkboxex column to it, here is my code:

TemplateField field = new TemplateField();
field.HeaderText = "Exporter ?";
gv.Columns.Add(field);
CheckBox cb = new CheckBox();
cb.Visible = true;

The problem is that I don't know how to add a checkbox to the TemplateField that I added to my gridview columns.

1) Add below code to GridView columns.

 <asp:TemplateField HeaderText="CheckBoxColumn" Visible="False">
            <ItemTemplate>
                <asp:CheckBox ID="checkBox" runat="server"></asp:CheckBox>                   
            </ItemTemplate>
 </asp:TemplateField>

2) Make checkbox column visible dynamically by adding OnRowDataBound event or just looping through GridView.Rows

int indexOfCBColumn = 0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   e.Row.Cells[indexOfCBColumn].Visible = true;
}



foreach(GridViewRow row in GridView1.Rows) {
   if(row.RowType == DataControlRowType.DataRow) {
      row.Cells[indexOfCBColumn].Visible = true;
   }
}

Thanks!!

You can add the code below into the GridView Columns.

<asp:templatefield HeaderText="Check Box">
    <itemtemplate>
        <asp:checkbox ID="cb" runat="server"></asp:checkbox>
    </itemtemplate>
</asp:templatefield>
