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()");
        }

Hello,

is it possible to set different VerticalAlignment-Properties for RadPanelItems in a RadPanelBar?

I want to vertical align the first item to top (fixed height) and then the second item to stretch with the User Control.

I tried this solution, but it won't work:

Greetings. 

I have just downloaded and installed the trial for Telerik WPF.  I require a Linear Gauge control.  I have read the documentation and my understanding is that the Linear Gauge control is a container/wrapper of the Linear Scale control.  Should there be a Linear Scale control in the toolbox, because if so, I am not seeing it in the toolbox (VS 2017)??  I was able to manually write some XML code per the example in the documentation for the Scale for my linear gauge, but I'm hoping that is not what is required and that the Linear Scale is a control where I can simply set some properties, etc.  Outside of manually writing code to create the scale, how do I implement a linear scale for a linear gauge control?

Thank you,

Don
