Hi,

I'm having some trouble using RadControls_for_WPF_2009_2_0813_TRIAL. I have used in a project RadWindow for WPF. "Sometimes" when I close a window the InvalidOperationException is thrown. I'm hoping to find help here, because for the moment I'm using the trial version of the controls, trying to demonstrate that this is a fine acquisition. Here is part of my stack trace:

Startup URI: ....xbap
Application Identity: file:///....xbap

Hi Guys

With the following data in item source

{1,2,7,4,9}
{1/1/2009,2/1/2009,3/1/2009,4/1,2009,5/1,2009}

N.B the dates are the 1st on the month.

 

The BarSeriesDefinition  is fine but width of the bars are very small , this is due to the fact that the control assumes there are zero values for all the rest of the days of the month. Now can i change this ?

Hi,
are the WPF controls completable with MS 2010? I download the WPF controls and trying for tree view in Microsoft 2010, it is not working and throwing errors like
"Could not load file or assembly .....................................Telerik.Windows.Data.Dll" or one of it's dependencies (Exception from HRESULT:0x80131515)."

The same thing is working OK with Microsoft 2008.
I need to work with WPF controls in Microsoft visual studio 2010.
Please help me out
Thanks,

Hi,

I am still very new to wpf and would like to know how i would add text to the progress bar. The demo has the textblock above the progress bar and not inside. My end goal is to have the progressbar in the gridview control on a per row basis.

Any help would be very appreciated

Kind Regards,

Clinton

Hi,

Pre the 2009Q2 release, I could select and scroll to an item by setting the IsSelected and IsCurrent of that item to true and use BringDataItemIntoView. That worked perfectly all the time (except when grouped, but that's another forum post ;)).

In the current release, this doesn't work correct all the time. If I have a RadGridView that can 'show' 17 rows for instance, and I try to select an item with that's outside the viewport, it won't get selected/made current (using SetIsCurrent and SetIsSelected), but BringDataItemIntoView will still scroll to the item.

Is that a bug or am I doing something wrong?

Hai,
    I am using rad 2D piechart for our application. In this i was binded 4 digit value, at this time the last digit hides in the corner(ex:If i want to bind 1589 it shows 589 only).Can i bind the values in mid of the Area?

Thanks in advance.

I've got a screen that has a few date pickers on it, used for Due Date, Start Date and Completion Date.

The software I'm writing has limits on how far forward/backward you can select a date, so a Completion Date can only be before or on Today's date, but not more than 1 week before today's date, likewise with the Start Date.

To implement this easily I've used the SelectableDateStart and SelectableDateEnd values.  These work well for my purposes, except for this case:

Users will often enter in a start date, then maybe 3 weeks later when the task is completed they come into the same screen to fill in the completion date.

The problem that occurs is that I'd like the already selected start date to be a valid entry in the RadDatePicker - the existing date shows up, but if the user happens to change the value, they can't get the originally selected start date back unless they exit the screen without saving.

What would be ideal in this situation is that in addition to the range of selectable dates you have an array/list, which allows you to specify other dates that can be selected that are outside of the range of SelectableDateStart and SelectableDateEnd.

Is it possible to get this feature introduced into the control?

anybody can help me.

Hello again,

I've got two more issues

1)
When I bind the radgridview to a linq to sql datacontext and do sorting on a datetime column, then I get the following error:

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

2) In your demo application, under DataSourceUpdates, there goes something wrong in my opinion.
When you edit a textbox, the binding with the gridview.CurrentItem doesn't function anymore. Also after resetting the form, the text won't disappear. I think this has something to do with the oneway binding. I solved the problem by using the selectionchanged event instead of binding the textboxes to the CurrentItem

With kind regards,
Thomas
