Do you know current version Telerik support property rowspan for rows or cells in RadGridView ? Can you help me that ? Thanks so much!

Hi guys,
     Is there a way to specify a converter parameter in this control?  I have tried to specify a ConverterParameter in the binding to the value property, but in the ConvertBack method of the converter, the ConverterParameter is always null.  Maybe this is due to something happening internally in the control.  There is also a ValueToTextConverter property, but you cannot specify a ConverterParameter either.  Basically I want to use one converter that would apply to a variety of masks.  Any help would be appreciated.

Thank you,
P

Hello, i would like to know if there's a way to modify the data fields editors in the AutoGeneratingFieldEventArgs event.
I can modify things like e.DataField.Label or e.DataField.Height but i wold like to know how to acces the editor fields (more specific, i want to modify let's say, the height, width or background color of the control).

Also in this event can i modify the type of the control that is being generate for a specific property?
Something like: if (e.PropertyName == "Name") choose a type for the generated control.

Thank you.

I am using both a RadTreeView and a RadCarousel and bind the root nodes of the tree view and the carousel to the same list of items. If the user change the selection on one control, I would like the app to automaticall change the selected item on the other control. I tried to bind the SelectedItem property on both control to the same object but that did work. Has anyone tried this before?  Thanks.

Hello!

I have a big Windows.Forms project, but we also use WPF controls.
I have two ElementHosts, and in each I have one RadGridView.

All was good, but now we need grouping, and have a problem with it.
Grouping works only for one of the grids. And more, it isn't works after close and open window again.

I cannot attach here my example, but can send it via e-mail, if you need it.

I am doing a review of 7 major chart controls for WPF and during my review of the RadControl for WPF I cannot find a way to bind two separate Line Series on a single chart to individual properties of an underlying view model.

My view model has two ObservableCollection properties.  FixedPoints is populated in the constructor to represent a collection of static data points that are known at startup.  DynamicPoints is populated via Rx's Observable.Interval to simulate a real time steam of data being plotted.

I want a single chart control to display two line series each plotting one of the collections mentioned, but it seems the only place I can bind to my view model is on the RadChart so I have a single ItemsSource to bind.  Is this correct?  I need to do this completely declaritively no code behind work arounds.

I found a sample that uses a collection of collections and sets the CollectionIndex of each SeriesMapping but that is completely against the MVVM pattern.  It means I have to design any view model according the choice of chart control.  It is also IMHO a very ugly implementation.

Hi, I have random problem with text search. When pressing on the key 'X', sometimes the item get highlighted but sometimes it doesn't.

Hi,

My situation is this: I have a RadGridView control with one or more columns defined as GridViewComboBoxColumn. These combobox columns are populated with a large amount of rows, and I want to provide to the users the same functionality as in a regular RadComboBox control: type in an input field the first few letters of an item they want and the combobox column auto-completes the first match in the list and scrolls to it.

Is there any solution to this? What I tried is using a custom column derived from GridViewBoundColumnBase, as in the demo GridView->Columns->Custom Column, but couldn't make it to work.

I'm trying to show the RadDatePicker in cells by default.  I know that I can use the built in editors, but I want the pickers showing by default without the user having to click into the cell.  So I made a control template based on an example I saw elsewhere in this forum doing the same thing for CheckBoxes.  The code I'm using is below:

(This is of course a cut down version of my full grid)

This works fine and shows the date pickers if the dates are all null.  However, if the dates are non null then the no rows display at all - this includes rows that have the dates as null.  I can scroll for some reason when this happens even though I don't see any rows, and I get the following information from the Output window:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.RadGridView', AncestorLevel='1''. BindingExpression:Path=UseAlternateRowStyle; DataItem=null; target element is 'GridViewRow' (Name=''); target property is 'NoTarget' (type 'Object')

I assume this is more to do with the rows not being there than related to the DatePicker not working though.

I'm using the latest release of the controls - 2009 Q2.

I've tried binding to DisplayDate as well, and this might work except that it's a DateTime rather than a DateTime? so I can't bind to it, since my dates are nullable.

Any ideas on how to make this work?

Hello,

I have a question regarding bar charts.

On this type of chart I need to be able to modify the height of each bar (like on a usual bar charts) but also the width of each bar (this is less usual...).

So all those bars need to be modifiable in height and width and have to be stuck together (no space between them).

Is it possible to achieve that with your library ? Do I need to use a special chart ? in 2D or 3D?

Thank you in advance for your help,

Regards,
