I use Office_Black theme in my RadGridView. Everything is good except the header border is bold(wider) than the row borders. It seems its thickness is more than 2 or 3 times than the row borders. How to modify it?

How do Format Date Column in Edit Mode of the grid

How do Format Date Column in Edit Mode of the grid. I am using the WPF controls. I have to display the date values in 'dd/MM/yyyy' format in edit mode. I see there is no EditorRequiredEvent in case of WPF controls.So how do I change the format in these case?
My problem is when I click on the cell, the RadDateTimePicker considers the date as MM/dd/yyyy and it displays empty value. For example 13/05/2018 will show empty because 13 is not a valid month. So how to change this so that the it shows the required date format in Edit mode? Please help

Multi-row update?

I would like to be able to select a number of rows in my grid. Then I would like to select one of the columns in that set and change the value for all the rows simultaneously. Is that doable? Are there any samples I can follow?

Thanks!

Error Applying Style to RadButton

Hello,

I'm developing an installation wizard, and i have a resource for radbuttons.

Everything seems ok upon creation, but when i put the mouse over the button or i press it i get the following error:

System.Windows.Data Error: 40 : BindingExpression path error: '(MaterialControls:MaterialAssist.MouseOverBrush)' property not found on 'object' ''RadButton' (Name='LoginButton')'. BindingExpression:Path=(MaterialControls:MaterialAssist.MouseOverBrush); DataItem='RadButton' (Name='LoginButton'); target element is 'Border' (Name='BorderVisual'); target property is 'Background' (type 'Brush')

I have no idea what is wrong.

Code for button in wizard:

<telerik:RadButton x:Name="LoginButton"

Margin="0 180 0 35"

HorizontalAlignment="Center"

Content="Submit"

Height="40" Width="105"

VerticalAlignment="Bottom"

Click="LoginButton_Click"

MouseEnter="LoginButton_MouseEnter"

MouseLeave="LoginButton_MouseLeave"

Style="{DynamicResource TestButton}"

CommandParameter="{Binding}"/>

Shape connectors issue

Hi,

I've been having trouble with shape's connectors. While you drag the connection and try to créate a new connection in another's shape connector it is really hard to hover over the connector and see it change its color to blue "créate connection".

Is there any way we can change how quickly or how big is the connectors área in order to make this easier for the user?

Here you can se a video of what ive said

Incorrect Footer Bottom Margin on printing

Good time of day.

We have a problem. When we creating RadDocument via RadRichTextBox, it's look great, but when we trying to print it, bottom margin is not great at all, it's at least three times greater, than on print preview. Even if we make PageMargin and FooterBottomMargin equals to 0.

In attached files you can see what we have in RichTextBox and in printed version...

Collapsed Groups lose Collapse on Refresh?

I have an application that dynamically hides/shows properties based on customization. I'm relying on groups to categorize everything. When I refresh the control, by making a property visible/hidden or adding a property, all the groups I have collapsed reset expanded. Is this a bug? Can I also set group collapsed/expanded from code?

Thanks!

(Image attached: all that should change is in the yellow highlights. I click a checkbox and add new fields. In the lower image, all the groups suddenly expand when the form is refreshed.
