Disabling select on right click in a GridView

In the lastest version of the GridView, it is now "builtin" that when a user clicks with the right mouse button on a row, it is selected as if the user did a CTRL+Click. I am however not able to disable this behaviour.

We use a context menu on right click and do not want the selected state of a row to change once a user does this. We get a lot of negative feedback about this.

How do I disable this rightclick -> select row behaviour?

Thanks,

Marcel

RadDataForm with expandoObject

Hello,

I want to display a DataForm for enter a new element in a grid. But this grid is generated dynamically.

For that, i use a: "dynamic data = new ExpandoObject()" and feed that with: "data.field1 = "string"; data.field2 = 10" and bind my DataForm on it: "<telerik:RadDataForm x:Name="RadDataForm" AutoGenerateFields="True"
AutoCommit="True" EditEnded="DataForm_OnEditEnded"
AutoEdit="True" CommandButtonsVisibility="Commit,Cancel"
CurrentItem="{Binding Path=DataContext.data, RelativeSource={RelativeSource Self}}"
Header="Hello world"
KeyboardNavigation.TabNavigation="Cycle">
</telerik:RadDataForm>"

My problem now, the DataForm change my Int type on string type...

Accessing aggregate function results for each group item

Hi,

I have rows in the grid grouped by a field - Currency. I have a column (Amount) for which I define aggregate function Sum. Result of aggregate function is shown in the header of each group. All works great.

Now I want to show a summary of all Currencies and total Amounts for each of them at the bottom of the grid. For the sake of this example let’s say I have 100 rows in the grid and only two distinct values for Currency field: USD and RUB.

I want to have summary that will look like this:
Total USD - 1,234.00
Total RUB - 13,023.00

Using Grid.AggregateResults property only provides me with a total aggregate across all currencies:
Total – 14,257.00
with no break-down by groups.

How can I achieve this without grouping my data myself – RadGridControl already did this, I don’t want to recalculate the same values again?

Thank you,
Dmitriy

[Solved] Change CurrentVisibleRangeText

Hi,

I want to apply a different CurrentVisibleRangeText dependant on what view definition the user is in.

So DayView would be in the format ddd dd\MM\yyyy

Timeline and MonthView would be dd\MM\yyyy - dd\MM\yyyy

So I've changed the CurrentInterval ContentControl to use VisibleRange instead of CurrentVisibleText :

<ContentControl x:Name="CurrentInterval"

VerticalAlignment="Center"

HorizontalAlignment="Right"

Style="{StaticResource NavigationIntervalStyle}"

Content="{TemplateBinding VisibleRange}"/>

Now how do I apply the NavigationIntervalStyle? So far I have :

<Style x:Key="NavigationIntervalStyle" TargetType="ContentControl">

<Setter Property="Margin" Value="5" />

<Setter Property="VerticalAlignment" Value="Center" />

<Setter Property="HorizontalAlignment" Value="Right" />

<Setter Property="FontWeight" Value="Bold" />

<Setter Property="ContentTemplate">

<Setter.Value>

<DataTemplate>

<Grid>

<TextBlock Margin="0 1 0 0" Text="{Binding Path=Start, StringFormat={}{0:ddd dd/MM/yyyy}}" Foreground="White" />

</Grid>

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

This works ok for DayView but obviously not giving me what I want for Timeline or MonthView - I would presume I would need another TextBlock linked to VisibleRange.End - but how to set the Visibility of this textbox so I don't get it in DayView? Also would it be at all feasible for MonthView to run off the actual Month date and not just what is visible.. i.e. so it says 01/07/2016 - 31/07/2016 and not 27/07/2016 - 31/07/2016 (which is the actual VisibleRange of the month).

Changing ItemsSource after applying filter not updating GridView Rows

I am changing ItemsSource of RadGridview.

gv.ItemsSource = enumerated;

gv.Rebind();

After that I am clearing all the Descriptors

gv.FilterDescriptors.Clear();
gv.SortDescriptors.Clear();
gv.GroupDescriptors.Clear();

Then reapplying all Descriptors.

gv.FilterDescriptors.AddRange(filters);
gv.SortDescriptors.AddRange(sorts);
gv.GroupDescriptors.AddRange(groups);

But the RadGridview is not showing new Items, instead showing items Filtered before.

GroupHeader IsSelected & Click Event`

Hi,

I want the ability for the user to be able to click on a Group Header (in DayView) and for the Group Header and Row to be Selected - however a few issues I cant seem to solve :

I'm overriding the GroupHeaderBaseStyle but can't seem to bind the Command on the GroupHeaderButton to my ViewModel - how do I go about achieving this so I can catch when the user has clicked on each GroupHeader?

There doesn't seem to be an IsSelected property for the GroupHeader - so how would I go about storing this information as per the user clicking on each header?

Thanks.

Drop preview line in ListBox

Hi,

I need to implement DragDrop feature between listBoxes and also re-order within ListBox. I know there is one good sample from Demo, see attachment screenshot. But What I am missing here is the Drop preview line. I know in RadTreeView, there is the default DragDrop behavior comes with a good Drop preview line and API for me to enable/disable it. How can I do the same for ListBox?

I thought about using RadTreeView to take advantage of the default DragDrop behavior, but don't know how to make the UI layout to look like this one in ListBox. Please advise if there is any alternatives to get the layout like the one in the demo, and the drop preview line in RadTreeView.

Many thanks,

Mingxue
