How to custom filter ASP.NET Telerik RadGrid date columns

The Telerik RadGrid for ASP.NET Ajax allows custom filtering on date columns by using JavaScript.

The user will normally need to be able to filter the date columns by writing a date inside the RadDateInput control and then pressing a key (e.g. Enter) or by choosing a date from the DatePicker filter control. Date validation can be done before actually doing the filtering. Also, other checks can be performed according to the logic of the application.

RadGrid datepicker filter

The desired functionality is achieved using the OnDateSelected client side event of the DatePicker.

The date format of the controls on the date column can be changed according to the culture or whatever logic.

The aspx page code can look like this:

AllowFilteringByColumn="true" onitemcreated="gridDate_ItemCreated">


ShowFilterIcon="false" >




The JavaScript function where the custom logic will be performed is the following:
function filterDateOnDateSelected(sender, gvwColName, filterFunction) {
var masterTableView = $find('').get_masterTableView();
var dtInput = sender.get_dateInput();
var dateValue = dtInput.get_value();
//custom validations can be done here
if (dateValue != "") {
masterTableView.filter(gvwColName, dateValue, filterFunction);
} else {
masterTableView.filter(gvwColName, dateValue, Telerik.Web.UI.GridFilterFunction.NoFilter);
}
}
Using the ItemCreated server side event of the grid, the date format is set and the javascript function is assigned to the column.

protected void gridDate_ItemCreated(object sender, GridItemEventArgs e)
{
if (e.Item is GridFilteringItem) {
RadDatePicker picker = ((GridFilteringItem)e.Item)["DateColumn"].Controls[0] as RadDatePicker;
if (picker != null) {
picker.DateInput.DisplayDateFormat = "dd.MM.yyyy";
picker.DateInput.DateFormat = "dd.MM.yyyy";
picker.ClientEvents.OnDateSelected = "function(sender, args) { filterDateOnDateSelected(sender,'DateColumn',Telerik.Web.UI.GridFilterFunction.GreaterThanOrEqualTo); }";
}
}
}
