[Solved] filters during postback on client-side databinding

[M van der Kolk]

Am I right that filters set on a client-side databound radgrid are not preserved during a postback?

Currently I have my own buttons to set a filter on the grid. When I press one of the buttons, this client-side function is called:

function actionFilter(obj, value)
{
    var tableview = grid.get_masterTableView();
    tableview.filter('Action', value, 'EqualTo');

}

I have one column which causes a postback. After the postback, the filter is gone and all records are shown. So if I want to preserve the filter, I have to save it programmatically?

Hello Patrick,

A possible approach is to save the filter expression onto a viewstate or session variable or any other similar instance and then load the filter expression in the Page PreRender event or so inorder to save filtering on postback. For better guidance, you can refer to this link and you can alter the logic according to your requirement.
