Setting Focus to RadpanelItem not working

Hi,

I want to set focus to a RadPanelItem from server side.

I have tried the following approach

RadPanelItem pnlitem1 = (RadPanelItem)TestPanelBar.FindItemByValue("TestPanelItem");
pnlitem1.Focus();
pnlitem1.Expanded = true;

But this logic is not working.

Can any one please help me how to set focus to RadPaneltem through server side.

Thanks,

RadGrid not Displaying Data After Upgrading Telerik Rad Controls

Good morning all. I was wondering if anyone else has has this problem. I upgraded my Rad AJAX Control dlls and suddenly my main RadGrid isn't working on one of my pages. Funny thing is the Grid works on all other pages. If I add the old dlls from the previous version it works perfectly. The markup and the back-end C# has not changed at all, just a simple upgrade. Any advice on how to fix this?

Repopulate resources when navigating calendar in Web Service mode

We have an issue where if a user opens the calendar to a date that excludes certain resources and then navigates to the next week, for example, where those resources should be visible, they do not appear. As I understand it this is a limitation of Web Service binding mode where a calendar rebind does not rebind the resources just the events. Is there a possible work around for this?

We can of course do a full postback for this but we would need to capture the date the user was intending to navigate to and implement a great deal more client side and server side logic to make sure we delivered them to their intended date.

UserControl Radwindows AjaxRequest

I know a lot of discussion are about it, probably i'm dumb enough to not see how to use them for my case.

ASPX: contains a couple of ASCX (ASCX1, ASCX2). It needs a radajaxmanager
ASCX2: within I have a radwindow. as i close it I need to perform an AjaxRequest

How to?

First, where do i place my javascript?

        function OpenNewsCategory(ID, SelCat) {
            var wnd = $find("<%=RadWindowName.ClientID%>");
            wnd.show();
            wnd.setUrl("mypgae.aspx?ID=" + ID);
        }

        function closeRadWindow(oWnd, args) {
            var arg = args.get_argument();
            var arguments;

            if (arg) {
                 if (arg.Index != '') {
                    arguments = arg.Index + "," + arg.bSender;
                    alert('closeRadWindow parameters ' + arguments);
                }
                oWnd.argument = null;
            }

            ajaxManager.ajaxRequest('closeRadWindow' + arguments);
        }

Second, I would like to manage the servside code of ajaxrequest within the usercontrol and the javascript too. is it possibile?
do i need radajaxproxy? if it's so, how?

Thank you

Setting Disabled Style Toogle Button

Hi!

We wrote an acsx control and everything seems to work well except for the disabled state. Is it possible to override the image when disabled? (See attached image.) This does not seem to work. It appears to use the enabled images and then sets the opacity.

Thanks!

[Solved] GridImageColumn not Sortable

I have a RadGrid with a GridImageColumn in it. I have enabled sorting and am able to sort all columns except the GridImageColumn. When I move the mouse over the GridImageColumn header, I do not have the option to click on it. I have gone through the example and can't see what I'm missing. I am assigning the image using the ItemDataBound event (see below). Seems like it must be something simple...

Here is the RadGrid definition:

<telerik:RadGrid ID="grdMain" runat="server" Width="100%" AutoGenerateColumns="False" ShowFooter="false"

GridLines="None" AllowMultiRowSelection="True"

ItemDataBound Event:

if (e.Item is GridDataItem)

{

e.Item.Cells[grdMain.Columns.FindByUniqueName("Update").OrderIndex].ToolTip = "Update";

e.Item.Cells[grdMain.Columns.FindByUniqueName("View").OrderIndex].ToolTip = "View";

bool _SystemAdmin = Convert.ToBoolean(DataBinder.Eval(e.Item.DataItem, "Enabled"));

((Image)(((GridDataItem)e.Item)["Enabled"].Controls[0])).ImageUrl = "~/images/check_mark_checked.png";

if (!_SystemAdmin)

{

((Image)(((GridDataItem)e.Item)["Enabled"].Controls[0])).ImageUrl = "~/images/check_mark_unchecked.png";

Drag appointment from outside Weekview-DateRange within Scheduler

I am trying to drag rows from a RadGrid containing all existing appointments to the scheduler in week-view. After dropping I want to check on collisions using your given clientside function overlapsWithAnotherAppointment.

Within the clientside RowDropping method I need to get the dragged appointment to pass it to overlapsWithAnotherAppointment. I tried getting this by using scheduler.get_appointments(). My problem now is the get_appointments() function only returns appointments which are visible within the Weekview-range.

We’re using Telerik 2011.2.915.40 using a custom SchedulerProvider in which we override the GetAppointments method. I can see this function does return all appointments, also the ones which are not visible.

What should I do so get_appointments() also returns the non-visible appointments ?

Thanks for any help,

Frank

Below are some code snippits of our implementation:



RadGrid from which rows are being dragged:



<

telerik:RadGrid ID="rgActiviteiten" runat="server" GridLines="None" OnNeedDataSource="rgActiviteiten_NeedDataSource" Width="100%" AllowFilteringByColumn="false" ShowHeader="false" OnRowDrop="rgActiviteiten_RowDrop" DataKeyNames="Activiteit_ID" EnableViewState="false" >

<ClientSettings AllowRowsDragDrop="True">

<Selecting AllowRowSelect="True" />

<ClientEvents OnRowDropping="rowDropping" OnRowDblClick="onRowDoubleClick" />

</ClientSettings>

<MasterTableView AutoGenerateColumns="False" DataKeyNames="Activiteit_ID" ClientDataKeyNames="Activiteit_ID" AllowFilteringByColumn="False">

<Columns>

<telerik:GridBoundColumn UniqueName="P_Naam" DataField="P_Naam" HeaderText="Product" ItemStyle-Wrap="false" ItemStyle-Width="335" />

<telerik:GridBoundColumn DataField="Activiteit_ID" UniqueName="Activiteit_ID" Visible="true" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Scheduler to which rows will be dropped:

<telerik:RadScheduler ID="rsSchedulerWithProvider" runat="server" ProviderName="MyDbSchedulerProvider"

Width="1018px" Height="100%" Culture="nl-NL" FirstDayOfWeek="Monday" SelectedView="WeekView"

HoursPanelTimeFormat="HH:mm" CustomAttributeNames="ActiviteitType_ID, Omschrijving, Activiteit_ID, Soort"

EnableRecurrenceSupport="false" EnableExactTimeRendering="True" OnClientNavigationCommand="OnNavigationCommand"

AllowDelete="false" AllowEdit="false" OnAppointmentsPopulating="rsSchedulerWithProvider_AppointmentsPopulating"

OnTimeSlotCreated="rsSchedulerWithProvider_TimeSlotCreated" OnResourcesPopulating="rsSchedulerWithProvider_ResourcesPopulating"

OnClientAppointmentEditing="OnClientAppointmentEditing" OnClientAppointmentInserting="CreateAppointment">

<AppointmentTemplate>

<i><%# Eval("Omschrijving")%></i>

</AppointmentTemplate>

<WeekView DayEndTime="22:00:00" WorkDayStartTime="08:00:00" WorkDayEndTime="22:00:00" />

<DayView DayEndTime="22:00:00" WorkDayStartTime="08:00:00" WorkDayEndTime="22:00:00" />

<MonthView UserSelectable="false" />

<TimelineView UserSelectable="false" />

</telerik:RadScheduler>

ClientSide function which handles the drop:

function rowDropping(sender, eventArgs) {

// Fired when the user drops a grid row

var htmlElement = eventArgs.get_destinationHtmlElement();

// Bij slepen van een appointment geen check

var isActiviteit = sender.get_id().indexOf('rgActiviteiten') > -1;

if (isPartOfSchedulerAppointmentArea(htmlElement)) {

// The row was dropped over the scheduler appointment area

// Find the exact time slot and save its unique index in the hidden field

var timeSlot = scheduler._activeModel.getTimeSlotFromDomElement(htmlElement);

$get("TargetSlotHiddenField").value = timeSlot.get_index();

var activiteit = null;

if (isActiviteit) {

var activiteit_id = eventArgs.get_draggedItems()[0].getDataKeyValue("Activiteit_ID");

// NEXT LINE WILL GO WRONG SINCE scheduler.get_appointments() DOESN'T CONTAIN THE DRAGGED ITEM IF IT'S ORIGINAL DATE WAS OUTSIDE THE WEEKVIEW-RANGE

activiteit = scheduler.get_appointments().findByID(activiteit_id);

}

// Calculate the end time of the new appointment

// By default, new appointments span 2 rows, so we multiply the minutesPerRow property by 2

var endTime = new Date(timeSlot.get_startTime().getTime() + scheduler.get_minutesPerRow() * minute * 2);

// Check if the new appointment is overlapping with one of the existing appointments

var app = overlapsWithAnotherAppointment(activiteit, timeSlot.get_startTime(), endTime);

if ( app >= 0 ) {

eventArgs.set_cancel(true); // Cancel the event to prevent showing the insert form

}

// The HTML needs to be set in order for the postback to execute normally

eventArgs.set_destinationHtmlElement("TargetSlotHiddenField");

}

else {

// The node was dropped elsewhere on the document

eventArgs.set_cancel(true);

}

PostBackUrl with parameters

How do I go about passing a parameter into the PostBackUrl property?

I would be interested in being able to do something like this:

<telerik:RadComboBox ID="combobox" runat="server" AutoPostBack="true" DataTextField="Text"

DataValueField="Value" PostBackUrl="somepage.aspx?somevalue={0}" Width="200px">

</telerik:RadComboBox>

Where {0} would be a property on the model I'm binding to the ComboBox.

Thanks,

ComboBox
