Reusing code for multiple GridViews on same page

[stoogots2]

I would like to reuse the code for gridview sorting for each of the several GridViews that I have on one page. I've not done this before, so I am seeking a more elegant and reusable solution than coding events for each of the 4 gridviews I have.

Have you implemented a method that sorts which you can call when ever a GridView needs to be sorted?

[stoogots2]

I am doing "custom" sorting so yes I have. The GridviewSortEventArgs do not specify the Gridview itself, so I'm curious how to tell the event handler which GridView to sort.

Ok, you've created a method that does sorting.

One of the parameters that your method requires should be a reference to the GridView that called the method.

For example:

Private Sub MyGlobalSortingMethod(ByVal theGridView As GridView, ByVal theSortParameters As GridviewSortEventArgs)
 
 'Sorting code
 
End Sub

Please note that I used ByVal in the above code.
The reason for this is because a GridView is an Object, which means that it's memory location is passed as the value....

If you're not using VB.NET, just ignore this.

OK, that helps, except that I don't know how to get the GridView control's name from the postback. What I am trying to do is have OnSorting point to the same method for 4 out of 5 gridviews on one page.

The "sender" parameter should be the GridView.

Insert embarrassed smile here. Thanks for your help.

No problem :)
Don't feel bad, I used to make the same mistakes when I first started using .NET.
It just takes some getting used to :)

Hi
I have already used this code. firstly , i had to face same problem. but
now is working properly. I think, your problem is same. You can make a common function and call on sorting. In this function you have to pass argument according to each gridview.

 Protected Sub gv1_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles gv1.Sorting
 
        Dim colum As String = e.SortExpression
        sorting(colum)
        binddata1()
 
 
 
    End Sub
 
 
    Function sorting(ByVal colum As String)
        hiddenSortColumnLeads.Value = colum
        If hiddenSortOrderLeads.Value = "asc" Then
            hiddenSortOrderLeads.Value = "desc"
        Else
            hiddenSortOrderLeads.Value = "asc"
        End If
    End Function

Implement this code.
