can we use both custom button and inbuilt button in datagridview
- by Srikanth Mattihalli
HI all,
I am using Datagridview in asp.net. I have used custom buttons of up and down in the datagridview along with edit,delete and paging options.
I am handling the up down buttons by raising events in rowcommand and the code is as below
string command = e.CommandName;
Response.Write(e.CommandArgument.ToString());
int index = Convert.ToInt32(e.CommandArgument.ToString());
int count = GridView1.Rows.Count;
int keyValue = Convert.ToInt32(GridView1.Rows[index].Cells1.Text);
string value = GridView1.Rows[index].Cells[4].Text;
SqlConnection conn = new SqlConnection(SqlDataSource1.ConnectionString);
SqlCommand cmd = new SqlCommand();
if (command == "up")
{
if (index > 0)
{
index = index - 1;
int keyValue1 = Convert.ToInt32(GridView1.Rows[index].Cells[1].Text);
string value1 = GridView1.Rows[index].Cells[4].Text;
cmd.Connection = conn;
cmd.CommandText = "UPDATE [category] SET [order_id] = '" + value + "' WHERE [category_id]=" + keyValue1 + ";UPDATE [category] SET [order_id] = '" + value1 + "' WHERE [category_id]=" + keyValue + ";";
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
}
else if (command == "down")
{
if (index < count - 1)
{
index = index + 1;
int keyValue1 = Convert.ToInt32(GridView1.Rows[index].Cells[1].Text);
string value1 = GridView1.Rows[index].Cells[4].Text;
cmd.Connection = conn;
cmd.CommandText = "UPDATE [category] SET [order_id] = '" + value + "' WHERE [category_id]=" + keyValue1 + ";UPDATE [category] SET [order_id] = '" + value1 + "' WHERE [category_id]=" + keyValue + ";";
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
}
Response.Redirect("Default.aspx");
Designer file
"
DeleteCommand="DELETE FROM [category] WHERE [category_id] = @category_id"
InsertCommand="INSERT INTO [category] ([categoryname], [navigation_url], [order_id]) VALUES (@categoryname, @navigation_url, @order_id)"
SelectCommand="SELECT * FROM [category] order by order_id"
UpdateCommand="UPDATE [category] SET [categoryname] = @categoryname, [navigation_url] = @navigation_url, [order_id] = @order_id WHERE [category_id] = @category_id"
After this my edit,delete and paging is not working bcoz of event conflicts. Can anyone plz help me on this, so that i will be able to use both custom buttons(up and down) and edit,delete and paging features.
