hi

I wrote below codes in the page and called in Page Load event.

The Txtaz TextBox value is empty in page load.

private void GetEstatInfo(int pageIndex)
{
    using (SqlConnection conn = General.GetConnection())
    {
        using (SqlCommand cmd = General.GetCommand("consultant_requestSearch", conn))
        {
            System.Globalization.PersianCalendar shamsi = new System.Globalization.PersianCalendar();
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
            cmd.Parameters.AddWithValue("@PageSize", PageSize);
            cmd.Parameters.AddWithValue("@Request_type", Ddlreq.SelectedItem.Text);
            cmd.Parameters.AddWithValue("@Consultant_name", Ddlmoshaver.SelectedItem.Text.Trim());
            DateTime Dateaz = new DateTime(int.Parse(Txtaz.Text.Split('/')[0]), int.Parse(Txtaz.Text.Split('/')[1]), int.Parse(Txtaz.Text.Split('/')[2]), shamsi);
            DateTime Dateta = new DateTime(int.Parse(Txtta.Text.Split('/')[0]), int.Parse(Txtta.Text.Split('/')[1]), int.Parse(Txtta.Text.Split('/')[2]), shamsi);

But below error occurs:
