Deleting Row From GridView With Stored Procedure

Question

Whats wrong with my code? I want to remove a row from gridview when I click delete hyperlink(button).

It shows that the value is out of range. What Should i do?

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) 
{
  cn = new SqlConnection(conStr);
  delCmd = new SqlCommand();
  cn = new SqlConnection(conStr);
  cn.Open();

  //delCmd.Connection = cn;

  delCmd = new SqlCommand("spDelEmployee",cn);
  delCmd.CommandType = CommandType.StoredProcedure;
  delCmd.CommandText = "spDelEmployee";
  delCmd.Parameters.Add("@EmployeeID", SqlDbType.Int).Value = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values);

  cn.Open();
  delCmd.ExecuteNonQuery();
  DataBind();
  cn.Close();
}

Stored procedure:

ALTER PROCEDURE spDelEmployee
@EmployeeID int
AS
DELETE FROM Employed WHERE EmployeeID=@EmployeeID
RETURN  

Answer 1

You can specify a specific cell in a GridView. In your code, you can just replace:

GridView1.DataKeys[e.RowIndex].Values

with:

GridView1.Rows[e.RowIndex].Cells[xxx].Text

where xxx is the 0-indexed column number that contains EmployeeID.

Heres how I solved my problem) It woks.

  protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) 
    {

        cn = new SqlConnection(conStr);
        cn.Open();

        delCmd = new SqlCommand("spDelEmployee",cn);
        delCmd.CommandType = CommandType.StoredProcedure;


        object id = GridView1.Rows[e.RowIndex].Cells[em.EmployeeID].Text.ToString();

        delCmd.Parameters.Add("@EmployeeID", SqlDbType.Int).Value = Convert.ToInt32(id);

        delCmd.ExecuteNonQuery();

    }
