Scheduler Appointment Context Menu crash

I was notified that code (ASP.Net) that has not been touched in months was now broken. We are using the Scheduler to handle the initiation of commands being sent to devices on a regular basis. Up until today, this was working just fine. I brought up the project and ran it in the VS 2012 debugger. Sure enough, when I tried to open the context menu for the appointment, the debugger intercepted a null reference in the javascript file RadContextMenuScripts.js at line 188. this._getContextMenuElement() returns null. I further tested it on Chrome and found the same behavior.

One interesting point is that the TimeSlotContextMenu works just fine.

The definition of the AppointmentContextMenu is:
<AppointmentContextMenus>
<telerik:RadSchedulerContextMenu runat="server" ID="AppointmentContextMenu">
<Items>
<telerik:RadMenuItem Text="Delete" Value="CommandDelete" />
<telerik:RadMenuItem Text="Execution Summary" Value="Summary" />
<telerik:RadMenuItem Text="View Commands" Value="Commands" />
</Items>
</telerik:RadSchedulerContextMenu>
</AppointmentContextMenus>

When the menu is opened, the following code is executed:

function RadScheduler1_AppointmentContextMenu( sender, args )
{
SelectedAppointment = args.get_appointment();
SelectedDate.val( SelectedAppointment.get_start().format( "MM/dd/yyyy" ) );
AppointmentContextMenu.show( args.get_domEvent() );
}

I traced from the last line and the crash happens when the menu tries to show itself.
If you would like to view what is happening, let me know and we can get that set-up.

Unwanted Heading Columns Appearing

A problem that we cannot explain or work around. Often when our end users right click on a table to edit some table properties, text formatting is completely changed, like a whole new style is applied, even when no actual changes were made in the properties dialogue, just by launching it and clicking OK. We found that the table was being changed, and a lot of TH were appearing. We then narrowed it down to the Heading columns field in the properties dialogue was defaulting to 3 and was being applied to the table when OK was clicked. We did not program any accessible features, and do not want this. Attached is a print screen of the Heading Columns field with a mysterious 3 in it, that we think is then being applied to the table.

How can we stop this, or programmatically access this field to keep it at 0.

Thank you.

grid with multi grouping levels and checkboxes

hello,

I have radgrid with multi levels grouping,

<GroupByExpressions>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="STORE_ID" />

</GroupByFields>

<SelectFields>

<telerik:GridGroupByField FieldName="STORE_NAME" FieldAlias="STORE_NAME" HeaderValueSeparator=""/>

</SelectFields>

</telerik:GridGroupByExpression>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="PROVIDER_ID" />

</GroupByFields>

<SelectFields >

<telerik:GridGroupByField FieldName="PROVIDER_NAME" FieldAlias="PROVIDER_NAME" HeaderValueSeparator=""/>

</SelectFields>

<GroupByFields></GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

grouping works very well, but i want to add a template header group foreach one to create a checkbox column (for each row, and group ).

how to achieve that ??

GridDateTimeColumn Edit Mode Problem

Hi,

I am so stuck in finding out how can i configure the datetimecolumn in edit mode. Situation is I have to enter time in minutes in the edit mode: HH:mm (24hrs time) so user may enter time say 59mins --> 00:59. I am using GridDateTimeColumn. It is displaying the time correctly in the grid because I am using the DataFormatString:
<tel:GridDateTimeColumn Datafield="MyTime" ...UniqueName="MyTime" ... DataFormatString="{0:HH:mm}"... PickerType="TimeOnly" />
But when I edit any row in the grid the MyTime column displays the time : 12:59 AM which is quite confusing.

If I use a RadTimePicker outside the grid the I can setup the dateinput view as:
<tel:RadTimePicker ... >
<DateInput runat="server" DateFormat="HH:mm" DisplayDateFormat="HH:mm" />
</tel:RadTimePicker>

I also tried to setup the properties of datatime control in ItemDataBound but it is not applying. Is there any thing like DateInput.... in GridDateTimeColumn, so that we can set the options (DateInput,No popup button etc) in Edit / insert mode.

Any help will be so much appreciated.

Cheers, Ali

Creating the RadGrid Programmatically - Sorting not working

Hi,

I've got a page with one Placeholder on it and nothing else. I've added the RadScriptManager and the RadGrid using the code below and the Paging works ok but the sorting doesn't? No error is thrown. It shows the sorting icons in the column heading but does not actually do the sorting.

If I do exaclty the same using the Designer pages it all works fine. It's trying to do things programmatically that I can't get it to work.

Why does Paging reposition on insert new record?

I am using an edit form template. Editing a record is fine, but when I select the "add new record button", the paging moves about 14 pages (I am using 50 rows per page). After cancelling or saving the record, the paging stays at that new paging position. My sqldatasource is sorted desc by the identity field. So I am no longer at the top (newest record). I even tried rebinding the grid after initializing(RadGrid.InitInsertCommandName). Why does the act of initializing the insert do this? Very strange, but I'm sure one of you know what I am doing wrong.

My question is is there any way I can create dynamically this Itemtemplate od radcombobox dynamically and populate it with data
Thank you

Here is my code

        {

            String pRequest = pGetLang; 

           RadComboBox radComboBoxLang = sender as RadComboBox;

           



            radComboBoxLang.SelectedValue = pRequest.ToUpper();

            bool p_test = MvcBeaDAL.CookiesManager.SetGetCookie(radComboBoxLang.SelectedValue);

        }

        protected void RadGridLang_Load(object sender, EventArgs e)

        {

            String pRequest = GetLang();

            pGetLang = pRequest;

            

            RadGrid pRadGridLang = this.FindControl("RadGridLang") as RadGrid;

            List<LanguageHost> radLang = new List<LanguageHost>();

            radLang.Add( MvcBeaDAL.WebServiceBea.GetWebLanguageID(pRequest));

           

            pRadGridLang.DataSource = radLang.ToList();

            pRadGridLang.DataBind();

        }
