Assuming we have the following grid

 

The Limit column does not expand but the Deductible column is shrunk from the left when we try to resize the Limit column (drag separator b/w Deductible and Limit columns to the left).

The expected behavior is:

1.Limit column should expand

2. Deductible column should shrunk from the right

 

Thank you,

We have been trying to achieve the following behavior:

1. From window, open a popup/modal dialog ().

2. From within the popup/modal dialog, open another popup/modal dialog ().

It works fine but when the second popup is opened and you click the first popup, the second active popup goes behind its parent.

We cannot use ShowDialog() since we want these popups in individual tabs. Meaning, I can open one tab and inside it. I can also open tab and a popup inside it. ShowDialog() blocks the whole application and user cannot switch between tabs.

 

Refer to attached images for details of the issue faced

 

s is causing usability issues since the user will never know how to bring the active popup back if they mistakenly click outside it on the first popup.

I use RadNumericUpDown in many places.  My application runs on a PC and on the Microsoft Surface and uses the Windows8Touch theme.   

My problem is that whenever the user types the + or - button of a RadNumericUpDown on the MS Surface, the Window Virtual Keyboard appears, immediately obscuring the very control you are using.  The user isn't trying to edit the text box, mind you, just tapping the buttons.

I can see the cause:  Whenever you tap one of those buttons, the edit control gets keyboard focus.  This triggers Windows (at a very low level) to pop up the virtual keyboard.

But if the user is only tapping the buttons, it seems that the edit box should not get focus.  That should not happen until you actually try to *type* in it.   And even if you think it *should* get focus, there at least needs to be a way to prevent it from happening.  

Here is what I tried:

1. I tried to setting the entire RadNumericControl's IsEditable property to "False" but this has no effect.  Even though the user cannot edit the box, tapping the UP or DOWN button *still* makes the edit control think it is being edited enough to give it focus and force that virtual keyboard to appear

2. I tried setting the entire control's "Focusable" property to "False" but that didn't work either.  The internal edit control still gets keyboard focus.  This is because the Telerik template for the control fails to pass the "Focusable" to its internal edit through TemplateBinding. 

I have managed to "fix" this by copying the entire RadNumericUpDown control's template and making it pass "Focusable" to its internal edit via the TemplateBinding.  Then I use this template for my RadNumericUpDown and set them to not Focusable.

But I don't want to copy the entire template that because a)it's overkill and b) my copied template is not using the Telerik Windows8Touch theme that I applied to everything else.  So it looks out of place and terrible.  Yeah, maybe I can copy stuff from the Telerik XAML files but again, I'd really prefer a simple property on the RadNumericUpDown.

Am I missing some simpler method here?  Does RadNumericUpDown give me a way to get at the internal edit control and prevent it from getting keyboard focus short of copying its entire template? 

Also, am I correct that it's internal edit should NOT get keyboard focus if you just tap the buttons (at least if it's not editable)?

I am hoping you can point me to an easier way.  

 

It's hard to control is it show or hidden.

now i can only use remove and add form behaviors.

ShowTrackInfo and ShowIntersectionPoints can not totally control whole trackball

Hi

I am testing the RadRibbonView using PRISM. The RadRibbonView is set up as a region with modules populating the the View with RadRibbonTabs. I am looking for an example on how to dynamically add closable tab items in a TabControl defined as a separate region in the Shell from the RadRibbonTabs with a contextual group attached to every specific TabItem. So that when I select different TabItems in the TabControl I get a differenct contextual tab in the RadRibbonView for every TabItem.

Is there an example of this you could point me to?

Hello,

How do I format data (e.g. in GridViewDataColumn) to have a "%" prefix?
We do not want the value to be multiplied by 100 (e.g. when user enters "1", it should show "1%" instead of "100%")

Also, when data is null, it should show an empty field, "", instead of "%".

 

Thank you,

Jan

Hello,

I have a grid with a GridViewPinRowColumn and I need to detect, when the user has pinned or unpinned a row. Is there an event which I can subscribe?

Best regards,
Thomas

Is there a way of changing what group headers are shown depending on which columns have been grouped? 

I have a small banking application which displays a breakdown of all fees.

AllFees.PNG shows all of the fees ungrouped

GroupedByDesk.PNG shows the desired behaviour of grouping on any column other than currency (sums all of the rows 'Amount' values exchanged into a single currency)

GroupedByCurrency shows the desired behaviour of grouping by currency alone (sums all of the amounts in that currency)

Where it gets more interesting is if you group by Currency and another column. The desired behaviour is to show ONLY the exchanged sum in the header down in each group, and child group etc., until the Currency grouping, where you ONLY display the currency sum, as demonstrated in GroupByDeskThenCurrency.PNG

I have some working code that prevents the exchanged sum aggregate being displayed (as long as the Currency is the first grouping), but it's still not quite what the desired outcome is. Said code:

private void GridView_Grouped(object sender, Telerik.Windows.Controls.GridViewGroupedEventArgs e)
    {
      foreach (Telerik.Windows.Controls.GridViewColumn col in this.GridView.Columns)
      {
        col.AggregateFunctions.Clear();
      }

      bool groupedByCurrency = false;
      bool addedFxdSumAggregate = false;
      
      foreach (ColumnGroupDescriptor gd in this.GridView.GroupDescriptors)
      {
        if (gd.DisplayContent.ToString() == "Currency")
        {
          groupedByCurrency = true;
          this.GridView.Columns["Currency"].AggregateFunctions.Add(this.currSumFunction);
        }

        if (!groupedByCurrency && !addedFxdSumAggregate)
        {
          this.GridView.Columns[gd.DisplayContent.ToString()].AggregateFunctions.Add(this.fxableSumFunction);
          addedFxdSumAggregate = true;
        }
      }

 

 

 

Hi,

I'm having difficulty trying to build a multi level hierarchy that has unknown levels.
I've read loads and loads of examples but they all assume the number of levels are known. However, in my case I may have "x" number of nodes, which may have "x" number of child nodes, which may have "x" number of grandchild nodes etc etc.

My data is drawn from an SQL database where I use the SQL 2008 HierarchyID data type to represent my hierarchy in the database.

I've built the following class for my products:





I then have the following method to download data from the database which I need to some how construct an ObservableCollection() which contains nodes "x" number of levels deep. Please note that some nodes may be 2 levels deep, others may be 3 levels deep, so forth and so forth.




I've found a post that discusses unlimited nodes, http://www.telerik.com/community/forums/wpf/treeview/templated-node-multiple-parent.aspx , but in the example given it has the following lines of code to build up unlimited levels:

Surely this is only valid providing you know the number of levels before runtime?


I guess I'm essentially looking for a generic hierarchy builder where the number of levels are unknown until runtime, i.e. when data is download from database.

Any help would be greatly appreciated.

Thanks for your time.

Hello,

This big can be reproduced in your demo application:

1. Open the GridView examples
2. In the available examples, select "Selection and Usability | Row Details"
3. Select a rowin the grid view
4. In the external Details Presenter, select Visible: nothing is displayed in the bottom. You have to select another row and then come back to show the details.

 

Also another problem: if the external details is inside a ContentPresenter (collapsed at the beginning), it can't find  the gridview.

To test this, replace your Border with a ContentPresenter.
