Hi Telerik,

When the RadNumericUpDown is in focus, I'd like to update the source in VM. I created a simple method to grab the focused element from the keyboard and update the source. The problem is the Keyboard.FocusedElement returned a type called PickerTextBox instead of RadNumericUpDown and thus the highlighted codes won't be fired. My question is how I can UpdateSource to NumericUpDown properly? The original problem is when the RadNumericUpDown is in focus and user saves the app, the RadNumericUpDown source won't be updated.

        private void UpdateFocusedTextBox()

        {

            //There is an issue when textbox is in focus, it won't update the source.

            //This workaround will try to find the currently focusedTextBox and update the source.

            object focusedTextBox = Keyboard.FocusedElement;

 

            if (focusedTextBox is RadNumericUpDown)

            {

                RadNumericUpDown rad = focusedTextBox as RadNumericUpDown;

                ((RadNumericUpDown)focusedTextBox).GetBindingExpression(RadNumericUpDown.ValueProperty).UpdateSource();

            }           

            else if(focusedTextBox is TextBox)

                ((TextBox)focusedTextBox).GetBindingExpression(TextBox.TextProperty).UpdateSource();        

        }

Hello,

I'm trying to use a RadColorPaletteView with my own list of custom colors, in this way:

<TInputControls:RadColorPaletteView Height="18" SelectionChanged="RadColorPaletteView_SelectionChanged" >
<TInputControls:RadColorPaletteViewItem Color="Red" />
<TInputControls:RadColorPaletteViewItem Color="Orange"/>
<TInputControls:RadColorPaletteViewItem Color="Yellow" />
<TInputControls:RadColorPaletteViewItem Color="Green" />
<TInputControls:RadColorPaletteViewItem Color="Blue" />
<TInputControls:RadColorPaletteViewItem Color="Purple" />
<TInputControls:RadColorPaletteViewItem Color="White" />
<TInputControls:RadColorPaletteViewItem Color="Black" />
</TInputControls:RadColorPaletteView>

In my app, the black doesn't show up.  Instead, I get a square that seems to have a transparent background.  If I hover close to the border of that square, sometimes it allows me to select it, but most of the time I can't select the square.

I've tried moving the black to other positions in the list, and tried the hex value instead of the name, and it seems to have the same problem.  Additionally, if I wrap the RadColorPaletteViewItems in a plain ListBox instead of the RadColorPaletteView, the "black" one still has the same problem.

Is there something I need to do differently?

I'm haiving trouble with the TileView. It's bound to a collection of entites. These entities have image contents in them. When the application loads the TileView loads fine. But when I try to add a new item to the collection, the sizing of the tiles goes wonky. Could it be because the images in the collection are different sizes (height and width)? They won't ever be all the same size.

Hello,

I would like to make a suggestion.

At the moment, I find most of the Telerik themes useless.

However it would be really nice if Telerik themes like Windows 7 theme in Q3 and older ones could be applied to ALL wpf controls (not only Telerik ones). This would allow us to provide consistent

It seems that your competition, DevExpress, did that already and people find it usefull.

I think most people here would like Telerik to provide this functionality.

Hi,

I am using XML as datasource. The data contains XML representation of ® and ™: &REG; and &TRADE;

My treeview is displaying them as it is: MyCompany&REG;

Is there any efficient way I can convert these markup strings back to symbols and display them in tree?

PS: I don't really want to use converts for such rarely occurring characters/symbols.

Thanks


 

I have a Windows Service that needs a significant amount of user input.  Yes, I can put those values in the app.config file but then that seems lazy. This UI includes the ability to configure the service, start/stop the service and a log viewer.  So, I'd like the Windows Service to pick up the values entered by the UI.  Does anyone have a "standard" or "best practices" way of doing this?  Or, even just a better idea than my own.

My current approach:
The UI's data context is an object that contains all of my UI entries.  Serialize the object as XML using XmlSerializer.  Then whenever the Windows Service cycles, go to this XML file and deserialize it.  Then, use that object in the Windows Service.

• My question on this approach is... what is the best way to tell the Windows Service where the UI was installed?  I don't want to hard code this because the installer could put it it on the D:\ or who knows where?  Once again, I think making the user enter this value in the app.config is a lazy approach on the developer front.  Ideas:
  • I attempted to use the Process of the UI to find the Environment.CurrentDirectory of the UI process but that doesn't seem to exist.  Remember, the UI starts/stops the service so I know the UI will be opened when the service first starts.  Anyone have ideas on this front?
  • When the UI is installed or starts the first time, I could save the directory to a registry setting... but that seems pretty old school.  Is there a better way to do this?

 

Any suggestions are appreciated. 

Thanks,
Joel

Hi,
I have a requirement that I need to export the Chart and the grid (updated the RadChart template to include grid) to PDF.
Is it possible through telerik chart control?

There are some forum explaning about converting the chart into image and put them into PDF, but here in my case there can be multiple charts, which can be viewed using navigation buttons (ex: First, Next, Previous, Last).

Let assume that user won't navigate to any of them, and just try to export them. Then that PDF must contain all the pages (charts).
Is it possible to have those charts without being displayed on the page?

Please reply ASAP.

Thanks,
Nitin.

I have a RadGridView that can be loaded with various different business objects, primarily containing double, int and string members for editing. The columns of some of these objects can be sorted, but on others, no column in the grid will sort. This is despite setting CanUserSortColumns and IsSortable to true. Strangely, grouping and filtering works on these objects. I have removed any custom CellTemplates in case that was the issue.

To figure this out, I attempted to listen to the Sorting event on the grid, but it never fires. Any hint as to what direction I should look? How does the RadGrid determine whether data can be sorted, aside from the xaml input?
