[Solved] Manipulating Input in RadGridView

Hi Telerik Support,

Good Day ;)

I am working on the following requirements:

Requirement #1: Implement a RadGridView which allows Cell Editing
Requirement #2: All Inputs are numeric. We currently have implemented a CellValidating event to check for numeric input.
Requirement #3: There are some special key that can allow some numeric value to be inserted. For example if we input "L" into the editing cell, we expect the value will be replaced with a number 1234567.

We tried to implement the Requirement #3 by adding some logic in CellValidating Event to intercept for "L" and change the e.Cell.Value accordingly. But it seems to be not working.

What would you recommend to implement the Requirement #3?

Thanks
Ric Yik

Crop Tool

Hi

Couple of points I wanted to give my opinion on.

I'm not sure if this was is supposed to happen, but in your example, if you have the crop tool on and then you hit save, the saved image will take the image inside crop rectangle and not the original full image. This most happens when the crop tools turns off it applies the crop before it saves.

In my opinion, the crop tool should have an apply button. Instead of the user having to hit the crop button again (or hitting another button to apply the crop), the user would hit "apply crop" which would apply it. Hitting the crop button would simply turn off/on the tool.

This would get around the fact it saves the cropped image.

Thanks..great product ps.

Custom Grid Header

Hi,

I was wondering if it is possible to have custom header in WPF RdaGridView where a header of 3 column would have a header parent similar to the group header idea. This only for personation purposes and doesn’t affect column functionality. Each column is bound to a field in the view-model. Here is illustration of the header we would like to have.

-------------------------------------------------------------------------------------

| | |-----------------------------------| |

Col1 | Col2 | Col3 | col4 | Col5 | Col6 | Col7 |

| | | | | | |

-------------------------------------------------------------------------------------

How to use ProgressBar with IsIndeterminate=True

Hello,

I want to use RadProgressBar in my code with the option IsIndeterminate=True.

This is the code:

this.progressBar.Visibility = System.Windows.Visibility.Visible;

//Do Some thing that blocks UI thread

this.progressBar.Visibility = System.Windows.Visibility.Hidden;

Once I run this I dont see the progress bar.

Is there something I need to do?

Should I put the progress bar call in a worker thread?

Can you please help me with some sample?

Thanks & regards,
Santhosh B

RadMenu visible after onclick event fires

We have implemented the RadMenu in a new application and when we click on a menu item it correctly fires off an event which launches a C++ MFC application and exits the click event. The MFC application launches without issue, but it is visible behind the menu which is still visible. If we click on the MFC app the Menu disappears.

Why would the menu not be closing here? Any ideas?

RadChart and hand-cursor

We use the RadChart in a DataTemplate.
We would like to show the hand-cursor when moving over the chart.

<Controls1:RadChart Cursor ="Hand" mapinfo:MapLayer.Location="{Binding Location}" Visibility="{Binding Hide, Converter={StaticResource BoolToCollapsedConverter}}" Width="32" Height="32" Background="Transparent" BorderBrush="Transparent" Name="pin" Content="{Binding GebyrChart}" >

But… the hand shows only when the mouse points to the border/side area of the chart. When moving to the middle, over the (pie) chart the cursor changes to the default arrow.

We have a PopUpMenu popping up on right-click. This does not work when the mouse is in the center of the chart.

[Solved] Does the PersistenceFramework work with GridSplitter

Hi If I have this scenario:

<telerik:RadToggleButton Content="Switch View" Width="90" Grid.Row="0" HorizontalAlignment="Left" IsChecked="{Binding Path=AlternitiveViewActive }" Checked="ToggleButton_Checked" Unchecked="RadToggleButton_Unchecked" />

<Grid Grid.Row="1" Name="gridUnTabbed">

<Grid.ColumnDefinitions>

<ColumnDefinition />

<ColumnDefinition Width="Auto"/>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<telerik:RadTabControl Grid.Column="0">

<telerik:RadTabItem Header="Exception" >

<ScrollViewer>

<TextBox Name="txtException2" TextWrapping="WrapWithOverflow" />

</ScrollViewer>

</telerik:RadTabItem>

</telerik:RadTabControl>

<GridSplitter Grid.Column="1" Name="tabSplitter" Width="4" ResizeBehavior="PreviousAndNext" Background="Gray" HorizontalAlignment="Stretch" />

<telerik:RadTabControl Grid.Column="2">

<telerik:RadTabItem Header="StackTrace">

<ScrollViewer>

<TextBox Name="txtStackTrace2" TextWrapping="WrapWithOverflow" />

</ScrollViewer>

</telerik:RadTabItem>

</telerik:RadTabControl>

</Grid>

Can I let the PersistenceFramework remember how the splitter was located ? And can I use it to remember window size, ToggleButton checked / unchecked status and so on ?

I did some experiments with the telerik:PersistenceManager.StorageIs then saved the status via IsolatedStorageProvider isoProvider but the splitter location remained the same... Any ideas ?

Best regards

BusyIndicator after login button pressed

Hi.
I'm trying to use BusyIndicator. I want to start it when the button login is pressed, so I've setted the property IsBusy to false when the windows startup and then to true when the button is pressed.
I'm working with the pattern MVVM so I've binded the property IsBusy with a property in the viewmodel initially setted to false and then to true when the button is pressed.

The problem is that the BusyIndicator is on the top of the window also if its property IsBusy is setted top false.

What I've to do?

Thanks and regards
Andrea Ferrari

Changing "selected item" color only

We decided to use the Vista style since it is the closest to what we wanted.
The only thing we need to change is the selection/hover color in all controls...
Where do I start ? I did not find clear info on how to do this...
Thanks !

How to change view definition date formats based in users local machine format.

How can I dynamically make sure the datetime format represents something close to what the users local machine format is for the date and the time ruler. This has to be able to support international date formats.

Also, I am not sure how this plays into the fact that I have a GroupHeaderTemplateSelector specifiied which also appears to have some kind of formatting involved.

<common:MetrixScheduleViewGroupHeaderSelector.HorizontalDayViewDateTemplate>

<DataTemplate>

<TextBlock Margin="4" Text="{Binding Name, StringFormat=dd dddd}"/>

</DataTemplate>

</common:MetrixScheduleViewGroupHeaderSelector.HorizontalDayViewDateTemplate>
