Hi,

I'm running into some issues using the KeyTipService with the RadRibbonView.

The first issue is that if the ribbon is minimized, the key tips seem to display most of the time, without popping up the ribbon tab. (See attached picture). I say most of the time, since once in a while it will actually work (the ribbon tab will open), but then sometimes after it does work (the ribbon tab opens), it might not close afterwards! (e.g., if the user clicks the application title bar instead of choosing a key tip).

The second issue is that when the ribbon is NOT minimized, the key tips seem to work pretty well, except for an annoying focus rectangle that I cannot seem to get rid of when displaying a menu (see attachment). I have tried setting IsFocusable to false and the like, but still can't get it to stop showing. Any tips on how to get rid of that focus rectangle (using RadContextMenu and RadMenuItem).

Finally, when the key tips do display, they display very slowly. i.e., when using ALT, then picking a tab, the key tips on that tab take a long time to display. So much so that you can see them pop up, gradually, from left to right. At first I thought it was a deliberate animation, but seeing that Office and other applications show the key tips instantaneously, I am wondering whether it's just a performance issue, because if the key tip the user wants is to the far right hand side, then they have to wait a couple of seconds to see it.

As for these three issues, the one I am most concerned about is the flaky behavior with key tips when the ribbon is minimized, because it looks out of place and users will have a difficult time trying to navigate it. They shouldn't have to have the ribbon maximized in order to use key tips.

Kind Regards,

Wayne.

I have a WPF app using MVVM design pattern.
as I am testing for memory growth, I have come across memory leak. I have been trying to fix for days without success. If possible someone can point out the issue.

after opening few windows and closing them, the memory grows, and the objects are still hanged in the memory.
this is for my windows:

I got this. if it can be helpful

as you noticed in the last details, it says 3 objects after opening the window and closing for three times. I have spent quite long time trying to figure out what is going on, but I couldn't. I worked on different screens with RadGridView and pretty much same controls and there is no problem. Did I miss out anything?
If you need further details, let me know
FYI: when RadGridView is commented out, there is no problem

We're using Telerik.WPF.UIControl_2015Q2 for .NET Framework 4.0

Thank you

Hi,

If two unpinned panes are next to each other in our mainWindow like shown in this example:
https://github.com/telerik/xaml-sdk/tree/master/Docking/OrderedUnpinnedPanes

In this if pane1 and pane2 both are in unpinned state, and inside pane1 if some button activates the pane2 and tries to bring it to the front, it fails.
Because in the time during which pane2 tries to come in the view during that pane1 is just going back to inActive autohidden state due to whichpane2 couldn't come in the view.

Can you please suggest me a solution for this problem. 
I need to fix this issue urgently.

Thanks

Hi,

I'm following the example of RestoredTilesToSpanMultipleRowsAndColumns_WPF on the provided developer examples and i have stumbled upon 2 problems:

1. This example doesn't work without defining the RowsCount, i.e., trying to use an infinite number of rows:

Error:

 2. Using this template, doesn't allow loading on an Window_LoadedEvent:

Result:

When i remove the template from the radtileview, both problems  disappear, but i cannot define the placement of items, i.e., Row, RowSpan, Column and ColumnSpan don't work anymore:

Example 1:

Result:

I can surpass this problem by using Position property of radtileviewitem, but there is a problem when an item's size is bigger, i.e., when i want an item to either span more than 1 row/column.

In resume, i need a way to either use the Multicolumns template with infinite rows, or a way to continue without the template but being able to define the position of each item, even when an item occupies more than 1 row/column.

Can anyone help me?

Regards

I'm trying to enable or disable the whole menu based on a value of a variable (i.e., SomeVariable). However, when using Style (in the following xaml) with telerik:RadMenu, the whole menu disappears?

<telerik:RadMenu.Style>
    <Style TargetType="telerik:RadMenu">
        <Setter Property="IsEnabled"  Value="False" />                                                    
        <Style.Triggers>                                                        
           <DataTrigger Binding="{Binding SomeVariable}"  Value="Draft"> 
                 <Setter Property="IsEnabled"  Value="True" />                                                        
           </DataTrigger>                                                    
        </Style.Triggers>                      
     </Style>                                                                                            
</telerik:RadMenu.Style>

Thank you

If the map background is bound to a property that has no initial value, the map will ignore the mouse unless using a child control. I only found one mention of anything simliar to this: https://arstechnica.com/civis/viewtopic.php?t=83073

I have many columns in the GridView. It works fine. But when I apply the filters in each column, the headers are not showing.

The header cells seem to be wrapped(Vertical height becomes big)

I tried to set the column's width as star or a fixed value. The filter icons are showing. By the way I set the header text wrapping. It seems no space to place the headers unless I remove some columns.

Any idea?

Hi,

I've an error on a gridview when I try to filter column. This is my code:

        private void SetFilter()
        {
            log.Debug("Start function SetFilter()");
            rgvMain.FilterDescriptors.Clear();

            CompositeFilterDescriptor compositeDescriptor = new CompositeFilterDescriptor();
            compositeDescriptor.LogicalOperator = FilterCompositionLogicalOperator.And;

            if (!string.IsNullOrEmpty(txtfilterCode.Text))
            {
                compositeDescriptor.FilterDescriptors.Add(new Telerik.Windows.Data.FilterDescriptor("LAB_CODE", Telerik.Windows.Data.FilterOperator.Contains, txtfilterCode.Text));
            }
            if (!string.IsNullOrEmpty(txtfilterDescr.Text))
            {
                compositeDescriptor.FilterDescriptors.Add(new Telerik.Windows.Data.FilterDescriptor("LAB_DESCR", Telerik.Windows.Data.FilterOperator.Contains, txtfilterDescr.Text));
            }

            //add all filter to radgrid
            rgvMain.FilterDescriptors.Add(compositeDescriptor);
            log.Debug("End function SetFilter()");
        }
