About inserting record into dynamically created gridview in asp.net c#
<p>I have created gridview dynamically on click event of button.I have 4 fields per row(First name,last name, relation,DOB) with link button for add(lnkadd).I used Itemtemplate, edittemplate, EditItemTemplate, FooterTemplate to design gridview. 
I used function to add rows to gridview in lnkadd click event as follows:</p>

<pre><code> tabemp = (DataTable)Session["tabempsession"];

        if (tabemp.Rows.Count == 1)
        {

            if (Convert.ToString(tabemp.Rows[0].ItemArray.GetValue(0)) == "")
            {
                tabemp.Rows.Clear();
            }
        }
        DataRow drow = tabemp.NewRow();

        //create new veriable of(textbox,dropdownlist etc) in ItemTemplate in grid view

        TextBox txtFName1 = (TextBox)mygridview.FooterRow.FindControl("txtFName1");         
        TextBox txtLName1 = (TextBox)mygridview.FooterRow.FindControl("txtLName1");
        DropDownList ddlRelation = (DropDownList)mygridview.FooterRow.FindControl("ddlRelation");
        TextBox txtDOB = (TextBox)mygridview.FooterRow.FindControl("txtDOB");

        //insert values into rows in tabemp table
        drow[0] = txtFName1.Text;

        drow[1] = txtLName1.Text;
        drow[2] = ddlRelation.SelectedItem.Text;
        drow[3] = txtDOB.Text;

        tabemp.Rows.Add(drow);
        Session["tabempsession"] = tabemp;
        //int f = tabemp.Rows.Count;
        mygridview.DataSource = (DataTable)Session["tabempsession"];
        mygridview.DataBind();
</code></pre>

<p>But i am not getting textbox values .ie(txtFName1.Text), its getting as null. Please give me suggestion for getting values of all controls inside gridview.
Asp.net C#
