RadGrid Export error -- No data exported

Hi,
I am using a RadGrid that has another RadGrid as item template. Finally Grid contains RadTextBox as ItemTemplate.

I want to export the top grid with all its children data. But no data is exported and an error "Unable to cast object of type 'Telerik.Web.UI.GridTFoot' to type 'Telerik.Web.UI.GridTableView'." occurs.

<

telerik:radgrid id="gvCategory" runat="server" headerstyle-wrap="false" allowpaging="false"

allowsorting="false" autogeneratecolumns="false" gridlines="None" showheader="false" onexcelmlexportstylescreated="gvCategory_ExcelMLExportStylesCreated" onexcelmlexportrowcreated="gvCategory_ExcelMLExportRowCreated">

RadAjaxPanel.AjaxPanelRequestEventHandler vs RadAjaxControl.AjaxRequestDelegate

Hi,

I am upgrading an application from Classic Telerik controls to the latest ASP.NET AJAX ones. I have replaced the following line of code

AjaxPanel.AjaxRequest -=

new RadAjaxPanel.AjaxPanelRequestEventHandler(ContentPaneControl_AjaxRequest);

with this one:

AjaxPanel.AjaxRequest -=

new RadAjaxControl.AjaxRequestDelegate(ContentPaneControl_AjaxRequest);

because the former would no longer compile.

It's crazy, but I can't even find where I got the idea for the second line. Anyway, the problem is that it works with some of my controls but not with others. For some controls it goes into ContentPaneControl_AjaxRequest, for others - it doesn't. The code is all in one script. They all go to that same script.

Any ideas?

Thanks,
Olga

Create RadAjaxManager in codebehind

Hi,

Is it possible to create RadAjaxManager in codebehind?

I have a master page and I am creating a RadAjaxManager in the OnInit method of the master page. Later when I try to ajaxify a control within an aspx page using the AddAjaxSettings method I created in master page I get Object reference not set to an instance of an object.

Master Page

protected override void OnInit(EventArgs e)

{

HtmlForm form = (HtmlForm)this.Controls[3];

form.Controls.Add(new RadAjaxManager());

}

public void AddAjaxSetting(Control ajaxified, Control updated, RadAjaxLoadingPanel loading)

{

HtmlForm form = (HtmlForm)this.Controls[3];

RadAjaxManager ajax = form.Controls[1] as RadAjaxManager;

ajax.AjaxSettings.AddAjaxSetting(ajaxified, updated, loading);

}

ASPX page

protected void Page_Load(object sender, EventArgs e)

{

(this.Master as PortalMaster).AddAjaxSetting(button, panel, loading);

}

Edit: I get the null reference error in ajax.AjaxSettings.AddAjaxSetting(ajaxified, updated, loading); line. All variables are pointing to correct objects (ajax, button, panel, loading).

Thank you...

Export to Excel(inbuilt in grid) with RadAjaxManagerProxy

Hi There,

I have a radgrid that is placed on the usercontrol. Grid is under RadAjaxManagerProxy.
I am not able to use the inbuilt Export to excel property of the grid

Although I have searched for the same and found that its because of asynchronous post back,
I have also written client side event(OnRequestStart) for the radajaxmanager on pageload event of the usercontrol, but not able to use the export inbuilt functionality.
Kindly suggest how to achieve this.

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

           if (manager != null)
            {
                manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(RadAjaxManager_AjaxRequest);
                manager.ClientEvents.OnRequestStart = "onAJAXResponseStart";
                manager.ClientEvents.OnResponseEnd = "onAJAXResponseEnd";
            }



        function onAJAXResponseStart(sender, args) {
            if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToWordButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToCsvButton") >= 0) {

                args.set_enableAjax(false);
            }
            else {
                args.set_enableAjax(true);
            }

        }

Thanks
Saurabh

appointment font size: chrome vs IE

Hello

I've looked at a lot of posts regarding formatting problems for appointments but am still having an issue...I want to increase the font size of appointments in day view to 14pt for printing purposes and have done so in the following way:

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataKeyField="ID" DataStartField="appStartTime"
   DataEndField="appEndTime" DataSubjectField="appSubject" DataSourceID="SqlDataSource2"
   Skin="Sitefinity" CustomAttributeNames="resourceLabelColour" >
</telerik:RadScheduler>

Private Sub RadScheduler1_AppointmentCreated...

   e.Appointment.BackColor = System.Drawing.Color.FromName(e.Appointment.Attributes("resourceLabelColour"))

   Dim i As System.Web.UI.WebControls.FontUnit
   i = 14
   e.Appointment.Font.Size = i

End Sub

In Chrome everything looks fine, however in IE 8 the bottoms of the letters get cut off (please see the two attached screenshots). I have tried changing various CSS properties but am not able to get it looking right in IE...

Thanks for any suggestions

Brian

Disable Left Click Sort (but keep menu)

I'm interested in shifting the right click column context menu to a left click. I've gotten this to work by binding to the OnColumnClick event and showing the menu in that way (though i also have to put in a timer and disable closing the menu for a short time - otherwise it shows and immediately hides itself). However, if the user clicks on the header text itself (rather than just the column background), the grid still wants to sort itself. Disabling sort fixes that problem, but then it also removes the sort functions from the context menu.

My context menu already has a number of custom elements in it, and i could certainly just add my own custom entries there. But i figured i would stop in here and see if there's an out of the box way to accomplish this goal. Can you turn off click to sort, but maintain the menu entries?

[Solved] Add appointment directly from TimeSlot Context Menus

Hi!

Can someone show me an example how to accomplish the following in RadScheduler?

The user selects the desired time slots with the mouse pointer and then right click to bring up a TimeSlotContextMenu designed something like this:

<TimeSlotContextMenus>

<telerik:RadSchedulerContextMenu ID="SchedulerTimeSlotContextMenu" runat="server">

<Items>

<telerik:RadMenuItem Text="Peter" />

<telerik:RadMenuItem Text="Adam" />

<telerik:RadMenuItem Text="Niclas" />

<telerik:RadMenuItem Text="Jones" />

</Items>

</telerik:RadSchedulerContextMenu>

</TimeSlotContextMenus>

Then when the user choose one of the menu items a booking should be done without poping up a booking form.

Is it possible? If so, how do I do it?

I'm using C# and the Rad v2010.3.1317.40.
