            cmnd.Parameters.Add("@Call_assing", SqlDbType.VarChar).Value = Label1.Text;

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'id'.
Error is quite clear. There is no column named ID when you did:

SQL

SELECT * FROM  Tech_data...

Make sure whatever columns you have defined and mapped to be expected in the dataset are present.

this code is working perfectly in another page y??

protected void Button1_Click(object sender, EventArgs e)
{
DateTime date = Convert.ToDateTime(TextBox1.Text);
SqlCommand cmd = new SqlCommand("SELECT * FROM Tech_data where Call_assign = @Call_assign and dateadd(dd, datediff(dd,0, [date_time]), 0) = @date_time ");

cmd.Connection = con;
cmd.Parameters.Add("@Call_assign", SqlDbType.VarChar).Value = DropDownList1.SelectedValue;
cmd.Parameters.Add("@date_time", SqlDbType.DateTime).Value = date.Date;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
Tech_grid.DataSource = ds;
Tech_grid.DataBind();
}

Your code, your environment. If it's the exact code and the 'workflow', it should work at both the place.

A simple use of F11 while debugging in VS might help. To me, your 'TechGrid' & 'GridView1' does not have same columns and you refer/expect an ID column in 'GridView1'

i removed this part

C#

con.Open();
      
        string s = "SELECT user_name FROM login" + " WHERE user_name='" + Label1.Text + "'";
        SqlCommand cmd = new SqlCommand(s, con);
        SqlDataReader Dr = cmd.ExecuteReader();
        if (Dr.Read())
        {
            con.Close();
        }

and placed only this part in Load

C#

private void LoadData()
{
DateTime datetime = Convert.ToDateTime(Date.Text);
            SqlCommand cmnd = new SqlCommand("SELECT * FROM  Tech_data where Call_assign= @Call_assign and dateadd(dd, datediff(dd,0, [date_time]), 0) = @date_time '");
 
            cmnd.Connection = con;
            cmnd.Parameters.Add("@Call_assing", SqlDbType.VarChar).Value = Label1.Text;
            cmnd.Parameters.Add("@date_time", SqlDbType.DateTime).Value = datetime.Date;
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            GridView1.DataSource = ds;
            GridView1.DataBind();
        }
