Dynamically Adding a Gauge

Hi all..
I want to use a gauge in VB 2010.So I will create a WPF user control project and add this into element host of my Final Winforms project(So now I have 2 projects in my solution). I have implemented this and its working fine also.
Now what I need is the end user ( he will be only using the winforms application) has to use this gauge control dynamically.

to be more specific, he wants to display output in gauge or in graph. so he has two options and he selected gauge and based on the parameters, SQL procedure is executed and the resultant dataset is binded with the gauge.

If he opted for graph then graph should be populated.

How can I achieve this

Thanks and Regards

Black window

Hello,

I'm using the Q1 2010 1.319 version of Telerik controls in a WPF application and I have a big mistake with RadGridView control.

When I initialize a RadGridView with a lot of rows, I have a black window which cover the entire screen and this window stays on top until the initialization isn't finished. When I say "on top" I would like to say that I can't see or put on top other windows (I can't back on my desktop too).

Is this problem is known ?

Thanks.

RadGridViewCommands.BeginInsert Command enabled when?

Hi,
I have a databound GridView and a RibbonBarButton conecting it to RadGridViewCommands.BeginInsert.
If there is data available (viewmodel.dataitems.Count > 0) then the BeginInsert Button is enabled, if no data is available - when I usually need the BeginInsert command - the button remains disabled.
If I set ShowInsertRow="True" and click on it, then the Button is enabled as well....

So, how can I enable the RibbonBarButton with Command="telerik:RadGridViewCommands.BeginInsert", CommandParameter="{Binding IsEnabled}" CommandTarget="my:GridView" for an empty RadGridView?

Thank you,
Hermann

[Solved] Grouping by entity type with RadGridView and QueryableCollectionView

Hi,

How can i group by entity type in a grid.

I have a few entity type derived from a base one.

I want to display all of them (common property) in a read-only grid grouped by their type.

I use TPT for my types (one table for each type), so I don't have a column containing the type.

Modify DragCue.DragActionContent when using IsDragDropEnabled

Hi,

I am using a RadTreeView setting the IsDragDropEnabled to true, instead of RadDragAndDropManager.AllowDrag.

My goal is to change the DragCue.DragActionContent to "Copy to" when the user presses the Control key.

_treeView.AddHandler(RadDragAndDropManager.DropQueryEvent,

new EventHandler<DragDropQueryEventArgs>(MainTree_DropQuery), true);

private void MainTree_DropQuery(object sender, DragDropQueryEventArgs e)

{

if (Keyboard.Modifiers == ModifierKeys.Control)

{

TreeViewDragCue cue = e.Options.DragCue as TreeViewDragCue;

cue.DragActionContent = "Copy To";

}

			e.QueryResult = true;

}

The DragActionContent property seems to return the current content but changes are not registered unless property is initially null.

Is this the proper method to alter the DragCue when using IsDragDropEnabled?

Thank you,
Justin

RadDragAndDropManager

Since installing Q2 2011 drag & drop is no longer working in my app?

Could there be a link between these 2 events??

Should I move over to the new dragdrop??

[Solved] Can I use Appointments and the AppointmentDialog without the ScheduleView?

I am looking to create something where users can setup recurring alerts to remind them of specific tasks, and I was hoping I could use the Appointment and AppointmentDialog to accomplish this.

Do you know if it's possible to use the Appointment and Appointment Dialogs without actually using a ScheduleView? I tried creating and showing a new AppointmentDialog,but it just came up empty.

My other big concern is how I would get the Dates for an Appointment for automated alerts. Is there a way to test if an Appointment lands on a specific date, or to get the Dates from an Appointment?

Thanks

Save/Load node expand/collapse state

Hi,

Assume I have fixed number of rows & node structure, and number of columns and columns data would change. When I come back to the screen, it should retain the previous node expand/collapse state.

Is there any way to achieve this functionality?

Thanks,
