</div>
Step 2: Logic on .CS page
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind_gr();
}
}
protected void gtn_get_Click(object sender, EventArgs e)
{
string id = string.Empty;
string Name = string.Empty;
foreach (GridViewRow gvr in gr.Rows)
{
CheckBox chk_sl = (CheckBox)gvr.FindControl("chk_select");
if (chk_sl.Checked)
{
id += gvr.Cells[1].Text + ',';
Name += gvr.Cells[2].Text + ',';
}
}
id = id.Trim(",".ToCharArray());
Name = id.Trim(",".ToCharArray());
Response.Write("City =" + id);
Response.Write("Name =" +
Name);
}
public void bind_gr()
{
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("City");
dt.Columns.Add("Phone");
dt.Rows.Add("Kandy", "Delhi", "8802***2564");
dt.Rows.Add("Sam", "Hr", "545502*2544");
dt.Rows.Add("Izhar", "Up", "95802*2452");
dt.Rows.Add("Vineet", "Delhi", "88022564***");
dt.Rows.Add("Kandy", "Delhi", "8802***2564");
dt.Rows.Add("Sam", "Hr", "545502*2544");
dt.Rows.Add("Izhar", "Up", "95802*2452");
dt.Rows.Add("Vineet", "Delhi", "88022564***");
gr.DataSource = dt;
gr.DataBind();
}
