How to Apply Sorting in ListView

• SortOrder: This property is used to define the sorting order for your specified field / fields in listview. Now we provide Ascending order and Descending order for you to choose from.
• AddSortExpression: This property is used to add your currently designed sorting expression to the collection of Sort Expression.

<kettic:PerListView ID="PerListView1" runat="server" ItemPlaceholderID="PlaceHolder1"
        DataSourceID="SqlDataSource1" AllowMultiFieldSorting="true" >
        
    </kettic:PerListView>

PerListViewSortExpression expression;
PerListView1.SortExpressions.Clear();
expression = new PerListViewSortExpression();
expression.FieldName = "field1";
expression.SortOrder = PerListViewSortOrder.Ascending;
PerListView1.SortExpressions.AddSortExpression(expression);

expression = new PerListViewSortExpression();
expression.FieldName = "field2";
expression.SortOrder = PerListViewSortOrder.Descending;
PerListView1.SortExpressions.AddSortExpression(expression);

Label1.Text = PerListView1.SortExpressions.GetSortString();
