Thanks for the response,

I have tried what you provided, also by just using "xamDataGrid1.SelectedItems.Records.Clear();" in a button.

Both seem to not work.

Thanks,

Matt.

Matt,

I did test this and it was working correctly. Can you please provide the sample that you are using and this is not having the desired effect?

Thanks,

Alex

When I click the area mentioned above it still selects a parent  record or does not deselect an item.

For some reason when a member is clicked, "dgLeft.SelectedItems.Records" is empty. even when I did not apply your code.

                    dgLeft.SelectedItems.Records.Clear();

Matt,

Actually, the are that you have circled is only for the XamDataGrid, and no other elements are there. You can modify this to search for any RecordPresenter (Label,DataRecord,etc). If none is found, you can call a ClearAllCommand. What you will see is the ActiveRecord remaining - it will look as selected, but the SelectedItems collection will be empty. If you want to go around this, you can set the Active Record to null, so that nothing appears selected. Here is the code snippet:

void xamDataGrid1_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)

        {

            RecordPresenter area = Infragistics.Windows.Utilities.GetAncestorFromType(

                e.OriginalSource as DependencyObject,

                typeof(RecordPresenter), true) as RecordPresenter;

            if (area == null)

            {

                xamDataGrid1.ExecuteCommand(DataPresenterCommands.ClearAllSelected);

                xamDataGrid1.ActiveRecord = null;

            }

            Debug.WriteLine(xamDataGrid1.SelectedItems.Records.Count.ToString());

        }

Thank you,

The code does work, but when you select a child node, and then click next to the [+] on the left it selects its parent. Is there a way to not allow it to?

Matt,

For the Microsoft.Windows.Themes.ScrollChrome element you need explicitly to add a reference to the PresentationFramework.Luna.dll. The Visual Studio will not do that for you, as it does for in other cases.

To make it scroll, you just have to remove e.Handled=true as this is preventing it.

Shoot,

I just noticed, that if you click a scroll bar.. the bar will not scroll.

I tryed:

Microsoft.Windows.Themes.ScrollChrome sc = Infragistics.Windows.Utilities.GetAncestorFromType(
                e.OriginalSource as DependencyObject,
                typeof(Microsoft.Windows.Themes.ScrollChrome), true) as Microsoft.Windows.Themes.ScrollChrome;

            // If clicking on the Scroll bar - do nothing
            if (sc != null)
                return;

but there is no such "Microsoft.Windows.Themes.ScrollChrome"

which if u put your mouse over the scroll bar and use a breakpoint.. you can see that is what the system recognises it as.

Thanks, Matt.

Thanks much, works great!

I now realized from your first screenshot that you are using 9.1 version - in 9.2 we have bubbles :) . So here it is why it's working with me and not with you:

In 9.2, we are not using nested panels for the nested records. So, when I am clicking beside the record, it returns null. In 9.1, this returns the presenter of the parent record, because it surrounds the nested records. That is why the parent record is selected. This however would require some more if-s, because you need to be sure when to deselect the record - basically in all the cases that you would not select it.

Here is a sample code snippet. Please test/run it and let me know of the result:

void xamDataGrid1_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)

        {

            RecordSelector rs = Infragistics.Windows.Utilities.GetAncestorFromType(

                e.OriginalSource as DependencyObject,

                typeof(RecordSelector), true) as RecordSelector;

            // If clicking on the record selector - do nothing

            if (rs != null)

                return;

            ExpansionIndicator expInd = Infragistics.Windows.Utilities.GetAncestorFromType(

                e.OriginalSource as DependencyObject,

                typeof(ExpansionIndicator), true) as ExpansionIndicator;

            // If clicking on the expansion indicator - do nothing

            if (expInd != null)

                return;

            CellValuePresenter cvp = Infragistics.Windows.Utilities.GetAncestorFromType(

                e.OriginalSource as DependencyObject,

                typeof(CellValuePresenter), true) as CellValuePresenter;

            // If clicking in the cells - do nothing

            if (cvp != null)

                return;

            // Finally check for the area and deselect the record

            DataRecordCellArea area = Infragistics.Windows.Utilities.GetAncestorFromType(

                e.OriginalSource as DependencyObject,

                typeof(DataRecordCellArea), true) as DataRecordCellArea;

            if (area == null)

            {

                xamDataGrid1.ExecuteCommand(DataPresenterCommands.ClearAllSelected);

                xamDataGrid1.ActiveRecord = null;

                e.Handled = true;

            }

        }

I noticed that as well. I am going to look into this and update this thread when I have more information on it.
