Code to check if a cell of a DataGrid is currently edited
Is there a way to determine whether a WPF DataGrid is in edit mode / which row is currently edited?
VB.NET
<Extension>
Public Function GetContainerFromIndex(Of TContainer As DependencyObject) _
(ByVal itemsControl As ItemsControl, ByVal index As Integer) As TContainer
Return DirectCast(
itemsControl.ItemContainerGenerator.ContainerFromIndex(index), TContainer)
End Function
<Extension>
Public Function IsEditing(ByVal dataGrid As DataGrid) As Boolean
Return dataGrid.GetEditingRow IsNot Nothing
End Function
<Extension>
Public Function GetEditingRow(ByVal dataGrid As DataGrid) As DataGridRow
Dim sIndex = dataGrid.SelectedIndex
If sIndex >= 0 Then
Dim selected = dataGrid.GetContainerFromIndex(Of DataGridRow)(sIndex)
If selected.IsEditing Then Return selected
End If
For i = 0 To dataGrid.Items.Count - 1
If i = sIndex Then Continue For
Dim item = dataGrid.GetContainerFromIndex(Of DataGridRow)(i)
If item.IsEditing Then Return item
Next
Return Nothing
End Function
C#:
public static TContainer GetContainerFromIndex<TContainer>
(this ItemsControl itemsControl, int index)
where TContainer : DependencyObject
{
return (TContainer)
itemsControl.ItemContainerGenerator.ContainerFromIndex(index);
}
public static bool IsEditing(this DataGrid dataGrid)
{
return dataGrid.GetEditingRow() != null;
}
public static DataGridRow GetEditingRow(this DataGrid dataGrid)
{
var sIndex = dataGrid.SelectedIndex;
if (sIndex >= 0)
{
var selected = dataGrid.GetContainerFromIndex<DataGridRow>(sIndex);
if (selected.IsEditing) return selected;
}
for (int i = 0; i < dataGrid.Items.Count; i++)
{
if (i == sIndex) continue;
var item = dataGrid.GetContainerFromIndex<DataGridRow>(i);
if (item.IsEditing) return item;
}
return null;
}
