Similar type of problem but this time for update/delete using stored procedures in gridview:

SQL

<asp:GridView runat="server" ID="gv1" AutoGenerateEditButton="true" AutoGenerateDeleteButton="true"
           OnRowEditing="edit" OnRowUpdating="update" OnRowDeleting="delete" <asp:GridView>

Code(.cs):-

public void delete(object sender, GridViewDeleteEventArgs e)
        {
            SqlConnection conn = new SqlConnection(str_con);
            conn.Open();
            SqlCommand cmd1 = new SqlCommand("DeleteInfo", conn);
            cmd1.CommandType = CommandType.StoredProcedure;
            cmd1.Parameters.Add("@s_id", SqlDbType.Int, 10, "s_id");//<----s_id is not primary key
            cmd1.ExecuteNonQuery();
            BindData();
            conn.Close();
        }

Stored procedure:-

SQL

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[DeleteInfo]
(
    @s_id int
)
as
begin
delete from info where s_id=@s_id
end

Try this one instead:

C#

int idToDelete = 29;
public void delete(object sender, GridViewDeleteEventArgs e)
        {
            SqlConnection conn = new SqlConnection(str_con);
            conn.Open();
            SqlCommand cmd1 = new SqlCommand("DeleteInfo", conn);
            cmd1.CommandType = CommandType.StoredProcedure;
            cmd1.Parameters.AddWithValue("@s_id", idToDelete);//user with ID 29 will be deleted.
            cmd1.ExecuteNonQuery();
            BindData();
            conn.Close();
        }

why would i use textbox to delete a row in gridview??

[no name] 6-Dec-11 3:32am

textbox1 contains the ID that you will be deleting. i updated my answer to make it clearer.

But I want to delete the row using "AutoGenerateDeleteButton" and don't want to take value from a textbox.

[no name] 6-Dec-11 4:41am

then find a way to get the id of the selected row then pass it as parameter as show above.

public void delete(object sender, GridViewDeleteEventArgs e)
        {
            int id = Convert.ToInt32(gv1.Rows[e.RowIndex].Cells[4].Text);
            SqlConnection conn = new SqlConnection(str_con);
            conn.Open();
