get_filterExpressions not working

[Stephen]

I am trying to retrieve the filter client-side to pass to a dialog window being displayed.  I am calling the get_filterExpression() method on the MasterTableView but an empty string is being returned.  Is this a bug or does it require something special.

function GetFilterData() {

    var filterString = "";

    var filter = $find(GridMasterView).get_filterExpressions();
    for (var i = 0; i < filter.length; i++)
        filterString += filter[i].get_columnUniqueName() + "~" + expression.get_fieldValue() + "~";

    return filterString;

}

Please let me know how I can accomplish this.

Thanks

Stephen

Hello Graham,

Here's a forum link which discusses on how to get your filter expression on client. This should probably help you out.
Getting FilterExpression Client-Side

So effectively what you are saying is that the function to get the filter expression client-side doesn't work.  This solution is basically a hack to bypass the client-side function.  However, how does this work in an ajax situation where only the grid is updated?

Hello Stephen,

RadGrid's client-side filtering and sorting expressions are maintained only for client-side binding. They are not mirrored from and to the server-side properties. Therefore, the post that Princy referred to, demonstrates the only way you can access server-side properties on the client, i.e. by saving them to hidden inputs.
