We have several xamGrids in our application but one (which just has text columns) is missing the border between two of the columns.
The columns can be moved, hidden, shown and resized OK. In some cases the border reappears, but for the most part it's missing.
The definition of the grid is no different to other grids that display fine.
<ig:XamGrid x:Name="LocationsXamGrid" Grid.Row="1" DataSource="{Binding LocationsDataSource, Mode=OneWay}" AutoGenerateColumns="False">
<ig:XamGrid x:Name="LocationsXamGrid"
Grid.Row="1"
DataSource="{Binding LocationsDataSource, Mode=OneWay}"
AutoGenerateColumns="False"
>
What have we missed in this case?
Andrew,
Thanks for this, I wasn't surprised by your findings and I'll take a look at the sample project to see if I can work our where our's differs. It won't be easy to provide a sample as our application is rather large and it would take some time to generate a cut down version.
As it's likely that this is caused by something we're doing, what I really would like is information on what controls or influences the display of the column border. Is there a property or style I can examine to see why it would be invisible in this case? Can the width of the column or the alignment affect it in any way? Can I make the line thicker? etc.
Cheers
Hello Chris,
The border you are seeing is a Border element named “Border” that is part of the template of a SimpleClickableContainer element that exists inside of the HeaderCellControl element template of the XamGrid’s default styles. There is nothing that actually effects this element or makes any changes to it, but you can change it by including the default style for SimpleClickableContainer and modifying the Border that is inside. As such, I believe the only things that should affect the visibility of these borders is if you are styling the HeaderCellControl or the SimpleClickableContainer element.
The default style and template for both of these elements can be found in the generic.shared.xaml file that is commonly found at the following directory with Infragistics controls installed:
C:\Program Files (x86)\Infragistics\<version>\WPF\DefaultStyles\XamGrid
Please let me know if you have any other questions or concerns on this matter.
Thank you very much. This was the information I needed. I copied the style and tweaked the border so it highlighted where the problem was.
It turned out to be some code we had written which I didn't think was getting called in this case - hence my confusion - that was overriding the column widths. Once I sorted that out the borders appears as expected.
I had thought it was our code but I knew we weren't overriding the styles so I dismissed it as I didn't realise it was the column widths that were the cause of the problem.
