Can't Get Sorting to Work

[Jamie]

I am using ASP.NET C# for my RadGrid and cannot get sorting to work. I have tried a couple of different ways to do it that I have found on this site, and some code from other sites, but the grid remains sorted the default way each time I try. Someone please help!

<telerik:RadGrid runat="server" ID="radProductsGrid" Skin="Default" AllowSorting="true" AllowPaging="true"
 OnSortCommand="radProductsGrid_SortCommand" OnNeedDataSource="radProductsGrid_NeedDataSource"
 AutoGenerateColumns= "false"  GridLines="None" ShowGroupPanel="false" PageSize="100">

 <MasterTableView Width="100%" AllowMultiColumnSorting="false" AllowNaturalSort="false"
  AllowCustomSorting="true" AllowSorting="true" AutoGenerateColumns="false">

  <Columns>

    <telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ItemNumber"
      DataField="ItemNumber" HeaderText="Item Number" UniqueName="ItemNumber">

    </telerik:GridBoundColumn>     

    <telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ProductName"
      DataField="ProductName" HeaderText="Product Name" UniqueName="ProductName">

    </telerik:GridBoundColumn>

    <telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="CategoryName"
      DataField="CategoryName" HeaderText="Category Name" UniqueName="CategoryName">

    </telerik:GridBoundColumn>

  </Columns>

 </MasterTableView>

</telerik:RadGrid>

 

 

 

protected void radProductsGrid_SortCommand(object sender, GridSortCommandEventArgs e)

        {

            GridTableView tableView = e.Item.OwnerTableView;

            if (e.SortExpression == "ItemNumber")

            {

                e.Canceled = true;

                GridSortExpression expression = new GridSortExpression();

                expression.FieldName = "ItemNumber";

                if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName
                        != "ItemNumber")

                {

                    expression.SortOrder = GridSortOrder.Descending;

                }

                else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)

                {

                    expression.SortOrder = GridSortOrder.Ascending;

                }

                else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)

                {

                    expression.SortOrder = GridSortOrder.None;

                }

                tableView.SortExpressions.AddSortExpression(expression);

                tableView.Rebind();

            }

        }

I found an answer on another Sort Issue in this forum. I had to remove the AllowCustomSorting="true" from my Grid and it sorts just fine now.

Hi Jamie,

I'm glad that you have found solution for your case. Note that in order to use any basic RadGrid feature like sorting, filtering, paging, ect. you should be sure that the custom functionality is disabled.
