C#

Label l = default(Label);
		l = (Label)v.FindControl("Label1");
		l.Text = dt.Rows[ctr]["Serial"] +  ",";
		l = (Label)v.FindControl("Label2");
        dt.Rows[ctr]["question"] = l.Text;

I got error l.Text = dt.Rows[ctr]["Serial"] + ","; in this line there is no position at row.

C#

cmd.Parameters["@password"].Value = this.TextBox2.Text;

      SqlDataReader dr = null;

      dr = cmd.ExecuteReader();

      if (dr.HasRows)
      {

i got error in this line dr = cmd.ExecuteReader();

thanks for valuabel replay

Your code seems incomplete or dont know what you want to do.

dt.Rows[ctr]["Serial"]

In this code what is ctr, Rows is jagged array where first boundary is columnName/Id and second boundary is RowID/RownNumber so your code should be like -

dt.Rows[ColumnName/ID][RowID]

What are you trying to do with this code?
