Filter radgrid on button click

I have a RadGrid with textbox filters which I have set to AutoPostBack = False. I've also hidden the FIlter Icon.

I have created a button in the command row for "Apply filters". I want to use the "Apply Filters" command button to evaluate the value of the column filter textboxes and then trigger the internal filtering event for the grid.

ie: user types into filter textboxes, then clicks "Apply Filters" which builds the FilterExpression and triggers the filtering event.

Could you help me out with an example, I have been searching but no luck.

I used UrlRewriter in my app, but I also apply this article: http://www.iis.net/learn/extensions/url-rewrite-module/url-rewriting-for-aspnet-web-forms

<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="None" />
</rule>
I appreciate if you can help me sort out the problem. Many Thanks.

Help! Disable RadScheduler rerendering on client side.

Hello,

I've created my own class inheriting from the RadScheduler in order to customize the view to display as an hebrew calendar - right to left with hebrew dates at the calendar header and at each cell header.

After working on overriding the CreateChildControls on the server side, finding the controls I need and changing them to fit my needs, I was able to put an empty scheduler control and see it rendering as I expected - everything worked great, I'll note I wasn't using ajax, and moving through months made a post-back and the calendar showed with all my hebrew strings and settings.

My next requirement was to call a webservice that can be called only from a client side code, so I've used jQuery and added the result using $find('<%=schScheduler.ClientID %>').insertAppointment(newAppointment); - the appointment wasn't added at first, but after looking at this: http://www.telerik.com/community/forums/aspnet-ajax/scheduler/insert-appointment-client-side.aspx#823397 I've changed the provider of the scheduler to a dummy webservice which returns empty lists and added a cancelEvent client handlers.
After doing this, every time I refresh the page I see my hebrew calendar for a second or less and then it renders to the english default radscheduler calendar with none of my hebrew settings or string, as if the entire dom elements are being re-created using javascript after receiving the empty list from the dummy webservice.

I can't seem to add the appointment using jQuery if the scheduler is not using webservice provider. On the other hand, I've worked a lot on customizing the scheduler on the server side, Is there's a way to disable that javascript rerendering of the control after a webservice response? I've tried disabling the OnClientRequestSuccess event with the cancelEvent (as described in the link above) but then nothing happens (I can't move through months)..

Help!!

This is some of my aspx code:

<hbc:HebrewCalendar runat="server" ID="schScheduler" TimeZoneOffset="03:00:00" SelectedView="MonthView"

DayStartTime="08:00:00" DayEndTime="22:00:00" EnableDescriptionField="true" Culture="Hebrew (Israel)"

OverflowBehavior="Expand" FirstDayOfWeek="Sunday" OnClientNavigationComplete="OnClientNavigationComplete"

OnClientAppointmentWebServiceInserting="OnClientAppointmentWebServiceInserting"

OnClientAppointmentsPopulating="OnClientAppointmentsPopulating"

OnClientResourcesPopulating="OnClientResourcesPopulating">

<WebServiceSettings Path="~/AppointmentsWebService.asmx" />

</hbc:HebrewCalendar>

<script language="javascript" type="text/javascript">

var adding_appt = false;

var scheduler;

$('#<%=schScheduler.ClientID %>').ready(function () {

loadAppointments($find('<%=schScheduler.ClientID %>'));

});

function loadAppointments(sceduler) {

var startDate = sceduler.get_firstDayStart();

var endDate = sceduler.get_activeModel().get_visibleRangeEnd();

$.getJSON('<%= GetApptUrl %>', function (appointments) {

for (var i = 0; i < appointments.length; i++) {

var apt = appointments[i];

var newAppointment = new Telerik.Web.UI.SchedulerAppointment();

var start = $.datepicker.parseDate("dd/mm/yy", apt.StartDate);

start.setHours(apt.StartHour.split(':')[0]);

var end = $.datepicker.parseDate("dd/mm/yy", apt.EndDate);

end.setHours(apt.EndHour.split(':')[0]);

newAppointment.set_start(start);

newAppointment.set_end(end);

newAppointment.set_subject(apt.Subject);

adding_appt = true;

sceduler.insertAppointment(newAppointment);

adding_appt = false;

}

});

}

function OnClientNavigationComplete(sender, eventArgs) {

loadAppointments(sender);

}

function OnClientAppointmentsPopulating(sender, eventArgs) {

if (adding_appt)

eventArgs.set_cancel(true);

}

function OnClientAppointmentWebServiceInserting(sender, eventArgs) {

if (adding_appt)

eventArgs.set_cancel(true);

}

function OnClientResourcesPopulating(sender, eventArgs) {

if (adding_appt)

eventArgs.set_cancel(true);

}

</script>

I've attached some of my hebrew calendar code to demonstrate part of the things I'm doing on server side (it's about 20% of the logic, it's not really relevant to the problem I'm having on the client side so I truncated most of it to avoid confusion):

public class HebrewCalendar : RadScheduler

{

protected override void CreateChildControls()

{

base.CreateChildControls();

var allControls = AllControls().ToList();

var allHtmlGenericControls = allControls.OfType<HtmlGenericControl>();

var minDate = DateTime.MaxValue;

var maxDate = DateTime.MinValue;

MakeViewJewish(allHtmlGenericControls, ref minDate, ref maxDate);

// Update top only if dates exists or in case this is a single day view

if ((minDate != DateTime.MaxValue && maxDate != DateTime.MinValue) || SelectedView == SchedulerViewType.DayView)

{

var header = allControls.OfType<LiteralControl>().Where(lt => lt.ID == "DateLabel").FirstOrDefault();

if (header != null)

{

switch (SelectedView)

{

case SchedulerViewType.MonthView:

header.Text = string.Format("<div class='header-date-text'>{0} ({1})</div>", header.Text, GetHebrewMonths(minDate, maxDate));

break;

}

// Swap prev/next buttons on the upper-left corner of the calendar

var prev = allControls.OfType<HtmlGenericControl>().Where(c => c.Attributes["class"] == "rsPrevDay").FirstOrDefault();

var next = allControls.OfType<HtmlGenericControl>().Where(c => c.Attributes["class"] == "rsNextDay").FirstOrDefault();

if (prev != null && next != null)

{

prev.Attributes["class"] = "rsNextDay";

next.Attributes["class"] = "rsPrevDay";

var prevHtml = prev.InnerHtml;

prev.InnerHtml = next.InnerHtml;

next.InnerHtml = prevHtml;

}

private void MakeViewJewish(IEnumerable<HtmlGenericControl> allHtmlGenericControls, ref DateTime minDate, ref DateTime maxDate)

{

foreach (var control in allDateControls)

{

try

{

string hebDay, hebMonth;

DateTime controlDate = DateTime.MinValue;

switch (SelectedView)

{

case SchedulerViewType.MonthView:

// Check if this cell wasn't handled already

if (control.Attributes["title"].EndsWith(")"))

continue;

// Add hebrew day string

controlDate = DateTime.Parse(control.Attributes["title"], Culture);

hebDay = GetHebrewDay(controlDate);

hebMonth = GetHebrewMonth(controlDate);

control.Attributes["title"] += string.Format(" ({0} ב{1})", hebDay, hebMonth);

control.InnerHtml = string.Format("<div class='eng-date'>{0}</div><div class='heb-date'>{1}</div>",

control.InnerHtml,

hebDay != "א'" ? hebDay : string.Format("{0} {1}", hebDay, hebMonth));

break;

}

catch (Exception ex)

{

throw ex;

}

#region Georgian to hebrew date converting

Code behind:

Public Class TestForm1

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

End Class

Problem must have code behind and enable set to false. See image:

P.S. The problem seems to be in IE rendering. No problem in FF.

Can’t open RadWindow from Master/Content page.

The example given in the RadControls documentation (getting started) is working fine in regular aspx pages, but I can’t get it to work from the Master/Content page. It could make it work in the Content Page after setting the property of “VisibleOnPageLoad” to TRUE, however it will display RadWindow automatically, when the page is loaded.
My problem is that I don’t want to display the RadWindow initially when the page is loaded. I need to display RadWindow only after a control (ex.Button) is clicked.
TheRadScriptManager is on MasterPage, the RadWindowManager is on Content Page.

How can I open RadWindow using a control (ex. Button) from a content page?
Thank You,
Thomas

This is my code from content page:

            <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
