SortingExpression is always ASC

[Toby]

Hi,

I have a grid that's bound to a webservice to provide its data. I have enabled sorting and

function onGridCommand(sender, args) {
        var OldSortExpression = SortExpression;
        var sortExpressions = sender.get_masterTableView().get_sortExpressions();
        // SortExpression (global) is passed to webservice on rebind of grid.
        SortExpression = sortExpressions.toString();
}

this works ok but the expression returned is always <columnname> ASC the icons change correctly on the grid column but it never changes to DESC when you click on the column again? I assume this is because I'm creating the grid dynamically at runtime and also changing the grid structure dynamically as in :

Any ideas?

thanks

Hello Toby,

Even though you change the grid structure on the server, you are databinding it on the client, right? And you are sending the filter expressions to your web service. Then you approach is similar to the one demonstrated in the RadGrid Programmatic Client-side Databinding demo. You can refer to it and see if there are any major differences in the approach you are taking with respect to binding the grid and performing sort/filter/page operations.
