I am having no luck trying to create a editable node. I am using XmlDataProvider and HierarchicalDataTemplates.
I have set IsEditable to True on the TreeView.
My DataTemplates look like this:
If I press F2 while on a node, I get a textbox that pops up on top -- but it says
System.Xml.XmlElement. I need to somehow get it bound to @name so that the two-way binding will function.
If I replace the text on my last node (the leaf) in the edit box (this is on the DataTemplate), then the TextBlock node shows up blank from then on but doesn't save it so it's not making it back to the XmlDataProvider .
If I edit the text on one of the HierarchicalDataTemplates, it seems to have no effect.
Thanks,
Timothy

Hi all,
I am trying to change the controltemplate for the DistinctFilterControl of each column in a grid (we need to change the colors to match our corporate colors). I used Expression Blend to grab a copy of the template, and started modifying the colors from there. I got the colors changed, but now the actual filter mechanism doesn't work - the dropdown of distinct values has no items listed. I didn't change the binding of the CheckBoxList (on line 116 of the template, below) at all... how do I fix this?
Thanks,
-Doug

I have an issue where when I try to declare a Grouping for my grid using XAML, the designer in VS2008 breaks.
When trying to group on Subject.Name of the DataBound object I get the following error in the designer.
"Subject.Name is neither a DataColumn nor a DataRelation for table Customers." This is more interesting because I'm not referencing anything anywhere called "Customers".

Justin Taylor

Greetings,
I have run into an issue when changing the GridViewRow background color. I have changed the background color based on IsAlternating in the example below: (Note that VerticalGridLinesVisibility is set to True)
In this example the grid will not show vertical lines with in the rows. I'm guessing this is due to how the controls are layered and the control (Border?) that serves as the row background is overlaying the base grid structure and hiding the grid lines.
I was going to attempt to just change the cell colors themselves based on whether or not they were in an alternating row, however I haven't found a way to accomplish that. I have been unable to find a way to tell if the cell is in an alternating row.
Is there tweak I can make to the control templates to allow grid lines to show in this scenario?
Thanks,
Chris
