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>
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 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.
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.
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
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.
