Hello everybody,

I'm going to implement a custom filter on webdatagrid client side. So I need filter on many columns.

But I have a occured error.

When I add the Array of filter, with "add_columnFilterRange()" , I throw an exception....(Sys.InvalidOperationException)

Look at my javascript code :

function Filter() {

var grid = $find("<%= Gri_Cli.ClientID%>");

var searchTextBox = $get("<%= Txt_Rec.ClientID %>");

var filtering = grid.get_behaviors().get_filtering();

// creer un tableau des filtres

var columnFilters = new Array();

for (z_I = 0; z_I < grid.get_columns().get_length() ; z_I++) {

if (grid.get_columns().get_column(z_I).get_type() == "string") {

// verifie qu'ona un filtre sur la colonnes

var columnFilter = filtering.get_columnFilter(z_I);

var colFilterExists = (columnFilter ? true : false);

if (colFilterExists) {

// condition du filtre

columnFilter.get_condition().set_rule($IG.TextFilterRules.Contains);

columnFilter.get_condition().set_value(searchTextBox.value);

// ajoute le filtre au tableau

columnFilters[z_I] = columnFilter;

}

}

}

// ajoute le tableau de filtres

grid.get_behaviors().get_filtering().add_columnFilterRange(columnFilters);  <--- error

if (searchTextBox.value != '') {

// applique le filtre

filtering.applyFilters();

} else {

// enleve rout les filtres

filtering.clearColumnFilters();

}

}

Check the error on the file attachment.

Why it doesn't work?

Could you help me please ?

Thanks in advance.
