<Columns>
<asp:TemplateField HeaderText="Mobile No">

    <asp:Label ID="lblMobileNo" runat="server" Text='<%# Eval("mobileNo") %>' />
    <asp:HiddenField ID="hfStudId" runat="server" Value='<%# Eval("StudId") %>' />

        <asp:Button ID="btnSendMsg" runat="server" Text="Send"

            onclick="btnSendMsg_Click" />
    </p>

我的按钮点击事件

sendSMS

my button click event

sendSMS

protected void btnSendMsg_Click(object sender, EventArgs e)
{
    int sms=0;
    if (Session["SMS"] != null)
    {
        sms = Convert.ToInt32(Session["SMS"].ToString());
    }
    if (sms > 0)
    {
    //foreach (GridViewRow gvr in grdvdiffrentMsg.Rows)
    // {
    //     HiddenField stuId = (HiddenField)gvr.FindControl("hfStudId");
    //     Label lblMobileNo = (Label)gvr.FindControl("lblMobileNo");
    //     Label lblMsg = (Label)gvr.FindControl("lblMessage");
         //if (lblMobileNo.Text != string.Empty && lblMsg.Text != string.Empty)
         //{
            dt=(DataTable)ViewState["MultiSMS"];
             objcommonsms.sendSMS(ddlMsgType.SelectedItem.Text, Session["SenderId"].ToString(),Session["UserId"].ToString(),sms,dt);
         //}

     //}
    }

}

for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            TextBox tb1 = GridView1.Rows["row index"].FindControl("Textbox1") as TextBox;
            UpdateFunction(tb1.Text);
        }
