I'm creating a page to enter employee's leave details in a dynamic gridview. Entry of data will be done by the from the footer of the gridview. When I try to get the values from the footer, all the text values as well as other values are coming as null or "".
Here is the code of RowCommand:
protected void gvEmployeeDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("ADD"))
{
TextBox txtAddEmpID = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddEmpID");
RadioButtonList rblFooter = (RadioButtonList)gvEmployeeDetails.FooterRow.FindControl("rblFooter");
TextBox txtAddDoj = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDoj");
TextBox txtAddLeaves = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddLeaves");
TextBox txtAddDesignation = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDesignation");
conn.Open();
string cmdstr = "insert into tblLeaves(EmpId,IsActive,DOJ,Leaves,Designation) values(@EmpId,@IsActive,@DOJ,@Leaves,@Designation)";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
cmd.Parameters.AddWithValue("@EmpId", txtAddEmpID.Text);
cmd.Parameters.AddWithValue("@IsActive", rblFooter.SelectedValue);
cmd.Parameters.AddWithValue("@DOJ", txtAddDoj.Text);
cmd.Parameters.AddWithValue("@Leaves", txtAddLeaves.Text);
cmd.Parameters.AddWithValue("@Designation", txtAddDesignation.Text);
cmd.ExecuteNonQuery();
conn.Close();
BindData();
}
}
And below is the gridview:
