Hi,

I am using MaskedInput control for currency value. I want to set a negative currency value in the masked input control. I get () in the control when I type - symbol. How to set mask which accepts negative value for currency type.

Hi,

I am using RadGridView with multiple/single field groupings based on conditions. When grid is first bound, it eats away first row of each group, which is event present in the datasource of the grid.

Code for setting default grouping when RadGridView is bound:

Edited: The missing row is restored when I toggle the radio buttons to change the mode (as below)
Below is the code to change the grouping:


Any ideas suggestions on this?

Hi,

I have a WPF application in which I rehost the .Net 4.0 Workflow designer alongside a RadTreeView. Items on the RadTreeView are dragged onto the designer and, when dropped, morph into self configuring workflow activities based on the context from which they were dragged.

I am using Telerik's DragDropManager and the AddDragEnterHandler and AddDragOverHandler methods to add handlers to the Workflow Designer View and that is working perfectly. However...

I need to control the drag cue over the designer and that is proving to be more problematic.

I first tried the following:

However the Designer_DragQueryHandler delegate would never fire.

So I thought it must be that the designer is handling that event before my delegate can be executed, so I tried the following:

This did not work either.

I am at a dead end on this now and would greatly appreciate any direction on how I might achieve this.

Thanks in advance
Chris

We are using autogenerated gridview and works fine but we have an issue with rebinding itemssource of filtered (by column default filters) by user.
If you refresh data (we do with background worker as datatable, then set grid itemsource to dataview.defaultview and call grid.rebind()) if the user has set column filters, it looses the ability to remove the filter but still reflects the filter in the grid.

Hi,

 

We are using RadRibbonView that contains RibbonTab with a number of Ribbon Groups.  I want to show a textbox (for search functionality) and I want to be aligned to the right of the ribbon view.   If I added this textbox inside a spate Ribbon Group, then that group is appended to the rest of the group, and not aligned to the right.  Also, I tried to create a grid inside the Ribbon tab and set all the group on one column, and then have that textbox on the second  column, but apparently Ribbon Tabs doesn’t accept Grid inside, I got a run time error.

 

Any idea how I can achieve this?!

 

Regards

In our application we use attached behaviors on RadControls in a number of places to avoid code-behind (mvvm pattern). These are used for some custom validation logic in grids, automatic significant digits displays on NumericUpDowns, and many others. After updating to the latest release (2011.3.1116.35) the following error occurs on all of these behaviors:

Cannot add content of type 'Behaviors.DynamicDecimalDigitsBehavior' to an object of type 'System.Windows.Interactivity.BehaviorCollection'.  Error at object 'Behaviors.DynamicDecimalDigitsBehavior' in markup file 'setdatarenderingpropertiesview.xaml' Line 270 Position 22.

The project is built in .Net 3.5, and as such we reference System.Windows.Interactivity version 3.5.0.0. 

Hello,

I am prototyping a user interface.  Basic slimmed down requirements are that I have a list of items on left side of page for the user to select.  On the right side of the list there will be a large view that contains information about the item that was selected in the list.  I have put together UI like this many times and also have used many telerik controls in our applications.  The TileView caught my eye for this one, thinking that I may be able to have something that serves the purpose and provides a bit of modern look and feel rather than just a list.

I practice MVVM and use prism with unity injection.

So what I am looking to get from this control is a templated list of items on left side in a single column.  When one is selected a templated view of the information related to the selection animates (maximizes) over to the right.  I do not want to ever have the items in a tiled view with several columnns and I do not want to have to Maximize in order to see information on the right side. 

Can you let me know if I am going to be able to achieve this functionality with the control?  In addition, if this is possible, could you provide a simple example for me to download?

Thanks,

Hello!
Is it possible to style ticks to have them inside chart area? 

Best wishes,
Christopher

I have a DataForm that I load via EF. In order to support "Edits", I need to implement the IEditableObject interface but I can't get it to work. I am almost certain I am not the first one trying to do this so if anyone can point me in the right direction would be great.

Thanks in advance.
