A work-around is to remove the columns one by one:
for (int i = this.dataGrid.Columns.Count - 1; i >= 0; i--)
{
this.dataGrid.Columns.RemoveAt(i);
}
when applying Grouping and RowHeight to the DataGrid and expand the row details, the following happens -> The DataGrid in the RowDetails only appears for alternate rows.
In addition the RowHeight does not apply to the Grouping Row.
Workaround:
Remove the RowHeight from the DataGrid and set the CellContentStyle property to the columns and set the TextMargin to the DataGridTextCellStyle, and ButtonMargin to the DataGridToggleRowDetailsCellStyle. Here is an example when setting them to 0:
<telerik:DataGridTextCellStyle x:Key="cellStyle"
TextMargin="0"/>
<telerik:DataGridToggleRowDetailsCellStyle x:Key="toggleStyle"
ButtonMargin="0"/>
<telerik:RadDataGrid.Columns>
<telerik:DataGridToggleRowDetailsColumn CellContentStyle="{StaticResource toggleStyle}"
IsFrozen="True"/>
<telerik:DataGridTextColumn PropertyName="Country"
CellContentStyle="{StaticResource cellStyle}"
IsFrozen="True"
CanUserReorder="False" />
<telerik:DataGridTextColumn PropertyName="Capital"
CellContentStyle="{StaticResource cellStyle}" />
</telerik:RadDataGrid.Columns>
When we have ListenForNestedPropertyChange property set to true and at some point Clear of the ItemsSource is called the newly added items to the collection stop to listen for PropertyChanged.
In order to make ListenForNestedPropertyChange work again toggle the value of the property. First set it to false and after that back to true.
When uprating the row details data, the data does not update in the UI. You have to resize the window, or collapse then expand the row details to see the updated value.
The behavior happens in 7.0.0 version. In 6.8.0 it works as expected.
I have the following issues when there is a DataGrid inside RowDetails template
1. The + does not change to - after expanding the details
2. Clicking the header in the inner data grid of line 2 does not work (seems disabled)
3. Sometimes cannot edit the inner DataGrid. tapping 2 times on the cell does not enter in edit mode
As of Telerik v7.0.0 this started to happen. In v6.8.0 the issue doesn't occur. The customer uploaded a sample project in the support ticket.
The DataGrid will crash when there is a bunch of CollectionChanged events with Grouping enabled. This happens in 6.6.0, 6.7.x and 6.8.x versions of the Telerik DataGrid.
In view mode, the scroll bar of the data grid moves only when the selected item is the first or last visible item in the display area of the data grid. But in edit mode, it moves regardless and it moves a lot more than usual.
I need a way for the scrollbar to behave the same for view and edit modes for a requirement in my project.
