Hi,

Is there an example or can someone assist me in creating a simple bar chart while consuming data using entity framework?
The query could be as simple as:

SELECT COUNT(Invoice_Header_Id) AS [Total Invoices], Created_By<br>

FROM Accounts_Payable.Invoice_Header<br>

WHERE (Date_Created >= CONVERT(DATETIME, '2012-12-19 00:00:00', 102))<br>

GROUP BY Created_By

I don't have an entity created yet. I would most likely use a store procedure and return a complex type.

Any help is appreciated.

Grouping Appointments in Timeline View

I am unable to get grouping to work, I can successfully create all the appointments I want but there is no indication of groups. I've copied source code from some Telerik documentation to populate the Resource property of the Scheduler, but no groupings ever show up.

Besides populating Resources and Properties I setup the Scheduler with

tlAvailability.ActiveViewType = Telerik.WinControls.UI.SchedulerViewType.Timeline

tlAvailability.GroupType = Telerik.WinControls.UI.GroupType.Resource

Also in some documentation (at least the Timeline Grouping in the Demo Application) calls are made to

Me.radScheduler1.Appointments.BeginUpdate()

Me.radScheduler1.Appointments.EndUpdate()

What does this do? Are they necessary (I am populating appointments with out this call)? Why aren't they called before editing the Resources?

I'm using Telerik 2013.2.612.20, VB, .NET 2.0

PivotGrid theme

We currently use the Breeze theme set through ThemeResolutionService.ApplicationThemeName, but it seems the theme does not fully support the new RadPivotGrid control.

Dimensions "groups" added to the pivot table does not have either filter buttons or context menus. Which they have in both the default theme and the Windows8 theme.

Setting the theme on the PivotGrid control does not help either, as the ThemeResolutionService has priority over this.

Is this a bug in the Breeze theme, or is the PivotGrid not supported? If not which themes support which controls, as we would prefer a theme which support all controls.

NullReferenceException

Hi,

i have a problem concerning a standard radtextbox (Q2 2010 => 2010.2.10.914).
Sometimes, but not everytime, when i start entering a value into one of my radtextboxes the following error will be thrown.
There are no events associated with these radtextboxes and i have absolutely no idea why this error appears.
Any help appreciated.

TimePicker - Null Value

I'm storing a DateTime in XML to tell an applicaton when it will shut down. I intend to use the value of "01/01/0001 00:00:00" to mean that we have no shut down scheduled. On the form that will get and set this value I am using two controls, a DateTimePicker and a TimePicker, to work with the value. (I'm open to other options.)

You already taught me how to handle the DateTimePicker so I'm initializing that control like this:

dtpShutDown.NullDate = Convert.ToDateTime("01/01/0001");

dtpShutDown.NullText = "";

dtpShutDown.Value = Convert.ToDateTime("01/01/0001");

I'm not quite there with the equivalent for the time picker. This gives me the "00:00 AM" text:

tpLogin.NullText = "";

tpLogin.Value = Convert.ToDateTime("01/01/0001 00:00:00");

I would like some way to just blank out the whole value.

I'm working with options while I wait for your response. A single DateTimePicker with a custom format to include the time may work out better than I had initially thought. (Regardless, I would like to know how to set the null time for the TimePicker.)

Thank you,
Gary

Export to Excel

Hello,

How can I export the data shown in RadGridView.
GridView.CellFormatting event is used to format and transformed the data (e.g., convert hours to seconds, change the format of the date, etc)

After exporting the data to excel using ExportToExcelIML I get the RAW data and NOT the transformed data shown in the gridview

Regards,
Bilal

How to lock a document as the first in a tab strip

I'd like to have my documents tab strip always show the same document in the first tab, but let the other tabbed documents be rearranged. I've got the close button functionality working (the first document cannot be closed, the others can), but I can't seem to get the drag/drop constraints working. I have made it so the first document cannot be dragged (by setting TabStripItem.AllowDrag), but it's still possible to drag a different document in front of the one I want locked as the first document.

In approaching this problem, I haven't been able to find an event I could cancel to achieve the effect. Another approach might be to rearrange the tabs if I notice they've changed (e.g. when the ActiveWindowChanged event fires), but its not obvious how to rearrange the tabs programmatically.

Any pointers?
