Hi Telerik Team,

I have a requirement in which I need to export the whole gantt area including non visible area (hidden inside scrollviewer) in to image. With the normal scrollviewer I could easily export the contents even in non visible area by passing the content of the scrollviewer. But RadGanttView doesn't have scrollviewer, instead it has two scrollbars. Kindly provide me the solution to export all gantt tasks including in non visible area to image.

Thanks and Regards,

Hi,

I'm buidling a window that displays a list of countries by continent. It consists of two elements:

• Combo box: displays a list of continents
• Grid view: displays a list of countries belonging to the selected continent

These are the requirements:

• Filter grid with combo box:

1. Filter rows based on combo box selection

• Keyboard support on grid:

1. Keep focus
2. Select first row by default
3. Navigate through rows with key up/down and page up/down
4. Open pop-up on Enter

• Mouse support on grid:

1. Open pop-up on click

• Refresh grid:

1. Periodically using a timer
2. After pop-up closed

I used the following technologies:

• C#
• WPF
• MVVM
• Telerik UI for WPF
• Caliburn.Micro

The problem I'm experiencing:

PreviewKeyDown on row not working after refresh grid.

• HOW: The ViewModel sets a new value for the bound ItemsSource property, and resets the bound SelectedItem property if possible.
• WHEN: Each time the grid receives new data:

1. initially
2. pop-up closed (after click or enter on row)
3. after periodic refresh

• RESULT:

1. PreviewKeyDown on GridRow is not handled
2. underlining of first cell disappears (I'm using the Material theme)
3. selection style however is visible

• WORKAROUND:

1. use keyboard arrows to change selected row (strange: arrows don't work, enter doesn't).

I've attached two screenshots: one regular, and the other one is showing the problem.

You can download my Visual Studio project following this WeTransfer link.

Please let me know if you need any further information.

The snippet below is from an application for a machine shop which has a rather utilitarian menu.... I've been asked to add hot keys to some of the items; one of the menu items (as seen in the code below) I need to add the F6 key as a hotkey (note the idendical Command for clicking vs hotkey)...   clicking on it works as desired, but the hotkey has seemingly no effect whatsoever.

What am I missing, or otherwise doing wrong? Thanks in advance for your help.

        <telerik:RadMenuItem Name="ToolsMenu" Header="Tools">
            <telerik:RadMenuItem Name="ToolsUseFinishLocationMenuItem" Header="Use Finish Location For Bin" Command="{Binding ToolsUseFinishLocationForBinCommand}" InputGestureText="F6">
                <telerik:RadMenuItem.InputBindings>
                    <KeyBinding Key="F6" Command="{Binding ToolsUseFinishLocationForBinCommand}" />
                </telerik:RadMenuItem.InputBindings>
            </telerik:RadMenuItem>
        </telerik:RadMenuItem>

If my tree node text is empty I want to display special text to the user but I when the node is edited I want the text to be blank.  How can I achieve this?  Currently when hitting F2 I still have the "(Not Set)" text displayed.  

        <telerik:RadTreeView telerik:TextSearch.TextPath="DisplayName" 

Hi

is it possible to add a row like the red marked ones between the normal rows?

The picture is from a Java-Webapplication. I like to have the same in my WPF-Application

And how can i do this with the Gridview?

Thx in advance

Hi,

Currently i am binding the column of RadGridView with an interface type; which causes the filtering on the column for the RadGridView to not show. 

Could you please provide a solution, where i can view the filter for a column that is bound with an Interface type.

Swapnil

Hello Telerik,

I have a RadGridView and I set to it an EventBinding like this :

=> I want to bind a command if the user wants to delete the selected row.

The problem is that all of the keys are fired the command, not only the 'Delete' key.

What is my error ?

Thank you.

Hello Telerik,

I'm using a RadDiagram containing shapes. These shapes has TextBlock to display some text.

I search to get the position of a TextBlock inside this RadDiagram.

I did it (tb is a TextBlock and Me.MirBuilderDiagram is a RadDiagram) :

The problem is that values are false : the top-left corner of the RadDiagram is set to 20;20, and for a TextBock next to this corner, I get the wrong value. I tried to get the position with the parent of the RadDiagram (a Grid), but I have the same result.

I attached 2 screenshots with :

- raddiagram : showing you the visual RadDiagram

- debug : showing you the debug with an attached watcher.

How I can get the good values ?

Thank you.
