Adding custom non-gridcolumn filter clientside

[staron]

Hi,
I'm trying to add a custom filter to grid using js, like this:
tableView.get_filterExpressions().clear();
tableView.get_filterExpressions().add("ContributionID='" + $get('cContributionID').value + "'");

And this works great. However; if we then filter using the gridcolumn it breaks on:
Telerik.Web.UI.GridFilterExpressions.prototype={find:function(_3e8){
for(var i=0,_3ea=this.get_count();i<_3ea;i++){
var item=this.getItem(i);
if(item.get_columnUniqueName()==_3e8){
return item;
}

Because item is just the filterstring.
I've read http://www.telerik.com/help/aspnet-ajax/grid_filter.html , but that requires that the filtered field is in the grid.

Please advice.

Hi staron,

The correct way to fire a filter command from the client is described in the article you have cited in your post. Could you elaborate on what you mean by "that requires that the filtered field is in the grid".

Thanks.

Hi,
Say that we have a field called SearchColumn in the db table. This field is not a column in the grid. As I understood in the article it would then not be possible to add a filter on that field your way.

Hi staron,

That's correct, however, you can set the columns visibility property to false and still get the filtering behavior.
