Hi all:
When I implemented the UI automation for DataGriadview, I found that: the runtimeID of cell in the datagridview is null.
The code is as followed:
public
class CommonDataGridView : System.Windows.Forms.DataGridView,
IRawElementProviderFragmentRoot,
IGridProvider,
ISelectionProvider,
IScrollProvider,
ITableProvider
{
……..
int[]
IRawElementProviderFragment.GetRuntimeId()
{
return
null;
}
……..
}
internal
class CommonDataGridViewRow :
IRawElementProviderFragmentRoot,
IRawElementProviderFragment,
ISelectionItemProvider,
IScrollItemProvider
{
……
int[]
IRawElementProviderFragment.GetRuntimeId()
{
return new
int[] { AutomationInteropProvider.AppendRuntimeId, _row.Index };
}
……
}
internal
class CommonDataGridViewCell :
IRawElementProviderFragment,
IGridItemProvider,
IValueProvider,
ISelectionItemProvider,
IScrollItemProvider
{
……
int[]
IRawElementProviderFragment.GetRuntimeId()
{
return new
int[] { AutomationInteropProvider.AppendRuntimeId, _cell.ColumnIndex};
}
……
}
For CommonDataGridView and CommonDataGridViewRow, the runtimeID for them in the UISpy can be returned the right value.
But for CommonDataGridViewCell, the runtimeID in the UISpy is null.
Could anyboby help me research the above code, is there any issue in it?
Or is there any other setting for runtimeId?
Thanks very much!
Why the UI Spy get the runtimeID is null
