Is it possible to disable the horizontal scrollbar? If yes how do I do this?
(RadPanelBar is bound to a HierarchicalDataTemplate).

Hi!

I've a  Tree, that has a RadContextMenu(Telerik's version of Context Menu). On every ItemMenu, I've an action.

I need to know, on which element of my Tree i've right clicked. How can I do this?

I tried to use the "SelectItem", but it seems the tree doesn't select on right click.

Thank you!

Hi All,

I am using the RadChart for WPF in my project for displaying the Chart as LineSeries, my requirment is like this:
 1) I need to add dataPoints dynamically by reading the output file for each Dataseries
  2) I need to add AdditionalYAxes for each Dataseries
  3) I need to Apply ForeGround color for each DataSeries
   4)And the same DataSeires color i need to apply color for related AdditionalYAxes
 
I have done upto the Above Three Steps and i am able to add AdditionalYAxes. But i am not able to Apply the color Style for the AdditionYAxes line and also the AdditionalYAxes is not start from X-axes, for now it is starting from X-axes one Step above.

I need to apply the color for AdditionaYAxes for the relating DataSeries and The Line should Start from X-Axes position.

i have attached my codeSnippet below:

I have attaching the Chart ScreenShot what i implemented.
Please see in Attachments
i am  calling the GenerateSeries Method every time for loading the X-Axis value and Y-Axes value.
Please any one help me how to apply color and starting position of AdditionaYAxes.
This is very urgent Requirment.

Hi,

On my RadChart i would like to "control" x labelstep thank to a property in a ViewModel (as you see I'm using MVVM pattern).

But when i try to use this mehod, i've got this message :

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Intervalle; DataItem=null; target element is 'AxisX' (HashCode=6253391); target property is 'LabelStep' (type 'Int32')

It seems that RadChart is loosing DataContext juste for this property. Any idea ? :D I probably should affect DataContext to "AxisX" but i don't know how to do it.

Here is my code :



Thank's !

HI.

I am building a grid in code, and needs to add rows ( and populate theirs cells ) in runtime.

Creating the columns was easy, but I battle to edit the cell values.

This is what I have tried.

grid.Items.AddNew()  creates a new row in the grid. I would now like to assign a value to cell[0] in the new row.
grid.Items[0] does not contain a method to access the cells.

How do I get to the cells?

I know that binding the grid to a datatable will be much easier, but I was hoping to access the cells directly, without having to create a table for the data first.

Thx!

 

 

I am unable to centre a child dialog window of type RadWindow. I create the window as following:


The window is always located in the top left corder. WindowHelper.MainWindow is a reference to a RadWindow, which I have checked is the main window of the application.

I need help. Am I overlooking something?

I've got a RadPanelBar with the Vertical/Horizontal Visibility properties set to Auto, which has been working initially when I display a user-control, but has some issues with resizing:

If I increase the height of my window, the vertical scrollbar's height seems to be aware of the increased height, and accounts for this, however, when I decrease the height of the window, the vertical scrollbar remains at the largest height it had reached previously. 

I recall some properties in WinForms you had to set in order to resize for grow-and-shrink, but I don't see anything like this in the WPF stack.  Is this resize behavior a known issue, or have I missed a setting that would make the scrollbar work as expected?

BTW - we're using version 2010.1.515.35 currently

Thanks,
Tony

Hi:
I need to design a cell template only for one column of the radgridview, How can do that? and
the cell template change depending the value of other column of the radgridview (in code behind).

please help me!

The RadTimePicker doesn't work correctly when it is placed inside a listbox. When you select a time from the dropdown, then the dropdown closes, but the binding is not updated.

The following snippet shows the problem:

<ListBox x:Name="multipleItemsPresenter" ItemsSource="{Binding}">

 <ListBox.ItemTemplate>

  <DataTemplate>

   <StackPanel Orientation="Horizontal">

    <telerik:RadTimePicker Width="80" SelectedTime="{Binding Path=Time, Mode=TwoWay}"/>

    <TextBlock Margin="20,0,0,0" Text="{Binding Path=Time, Mode=OneWay}">

   </StackPanel>

  </DataTemplate>

 </ListBox.ItemTemplate>

</ListBox>

I guess the ListBox and/or ListView intercepts the click, because it does work fine with an ItemsControl.

Is it possible to sort a GridViewDataColumn by the result of the converter rather than the object the column is bound to?
