Hello, I was wondering if I could prevent the user from dragging the alert off screen limits, I did find IsRestricted property here https://docs.telerik.com/devtools/wpf/controls/radwindow/how-to/prevent-dragging-off-the-screen

But I could not manage to apply it to one of your predefined dialogs (Alert, Prompt, Confirm). Is there any way to do it? Couldn't there be a simple property in the DialogParameters?

Thanks in advance,

Luís Henrique

1. Add items (click add new item).
2. Select item (select grid view row).
3. Change Quantity or Unit Price in grid view cell, the sum quantity and line total updated.
4. Change Quantity or Unit Price in other control (textbox), the sum quantity and line total not updated.
5. Add New Item or delete an Item. The sum quantiy and line total updated.

How can I fix the change quantity or unit price in other controll will update the sum quantity and line total?

Thanks

When editing a cell in a RadGridView, the normal behavior for the escape key is to leave edit mode but retain focus on the same cell; if the enter key is pressed, to commit the edit and advance focus to the next editable cell.

My boss would like for me to modify the behavior so that if enter is pressed but the cell's value has not changed, to act as if it were the escape key instead. While I have been able to cancel the commit, but the focus still advances to the next editable cell, and that's not what he wants.

What is the best way to achieve what we're looking for? Thanks in advance for your help.

Is there a way to format a text being edited of RadNumericUpDown text? 

For example, to show thousands white-space separator like 1 000 when user in a textbox actually is entering 1000

GridViewDataColumn has DataFormatString property which formats entered text after edit is finished, but we want to format it dynamically during editing when textbox focus is not lost and user keeps typing

Thanks

Hey everyone,

I'm currently working on implementing the Telerik charts into an application as a replacement for our current charts, however there's a ton of functionality that will be missed out on if I simply just replace the charts.

I'm testing the functionalities of each charts against each other at the moment and there's one thing that sticks out.

I need to be able to scroll and zoom on each of the axes independent of the entire charts zoom and scroll status.
The way its implemented into our applications charts is by simply clicking and dragging the axis for panning and mousewheel for zooming, however this implementation isn't set in stone.

Thanks for checking in,

Seb

hello

Could tell me how to use MapMouseClick of RightButton ?? 

We use Display attributes to govern exclusion of columns and to define headers and string lengths.  This work well with the RadGridView, but doesn't seem to be supported in the VirtualGrid.  Is this true or have I missed something?

Examples:

    [Display(AutoGenerateFilter = false, AutoGenerateField = false)]
    public int ID

     [Display(Name = "Status", ShortName = "Status", ResourceType = typeof(IC.RES.Properties.Resources), Order = 5000)]
     public String StatusLiteral

Hi,

I have some questions to know the best practice to reuse styles overriding theme's ones.

My solution is organized as this:

    - The main exe is in Smag.MSH.csproj

    - My custom controls are in Smag.UI.Wpf

   - All the styles are defined in Smag.Styles.csproj

I'm using implicit themes, so Smag.Style embeds:

  - xaml files from Windows 8 theme for all used controls

  - xaml files overriding default themes for some controls
   eg: in MyRadGridView.xaml

The main exe merge the theme's and my own resources like this:

What is the best pratices to reuse all the styles (theme's default one en those i have overrided) in Smag.UI.Wpf ?

The default style are currently not found:

Raise an error saying RadListBoxStyle is not found, but the right xaml is included in app.xaml

Event using this way, it doesn't work:

As it's a DLL, there is no app.xaml to merge ressources, doing it in each control like this seems to me not being performant:

Thanks for some more guidelines, the official documentation is not enough.
