Hide the GridViewIndentCell

[Charlie]

I have 2 questions.
1.)  How to hide or have the GridViewIndentCell to have 0 width using a HierarchyChildTemplate to do an Hierarchy Grid Parent-Child? (Not using RowDetails, and I have grouping disabled).  The parent and child have the same column headers (I display the parent, but I hide the child).  I want the child columns to line up with the parent headers, but I can't get rid of the GridViewIndentCell.

2.)  How do I kept the Child Column with the same as the Parent Width if I allow the user to resize the Parent Column? 

An extact example of each would be great.

Thanks,

Charlie J.

Hi Charlie,

If you want to be able to access GridViewIndentCell, you have two options:

1.Edit the template of a GridViewRow and find the part IndentPresenter, set its Visibility property to Collapsed.
2.Create a simple implicit style that is targeted at GridViewIndentCell and set its Visibility property to Collapsed.
Also you can remove the default padding in HierarchicalChildPresenter in GridViewRow's template.
Attached is a sample approach that demonstrates these techniques.
Considering your second requirement, you may take a look at this forum thread for a reference on the same issue.

Thanks Vanya,

Your sample worked fine until I added  AlternateRowStyle to the Parent Grid.  All the Alternate Rows had the GridviewIndent to show up where the other rows had it correctly removed.  You can reproduce the problem by adding  AlternateRowStyle to your Parent Grid in the sample you sent me.

I am trying to implement Question #2 based on the Forum post you reference.  I will let you know how that turns out.

Thanks,

Hi Charlie,

 
This is really strange issue. Can you please send us a small application with your custom AlternateRowStyle that demonstrates such a behaviour ?

Hey Vanya,

I made a mistake and left a Setter off the Style for the GridViewRow Style.  It is working just fine now.

Thanks,

I used option #2 to collapse the GridViewCellIndent by putting the following into my UserControl.Resources:

<Style TargetType="telerik:GridViewIndentCell">
    <Setter Property="Visibility" Value="Collapsed" />
</Style>

However, it now looks a little odd because the indent cell for the group header does not have a border on the bottom when the group is expanded, but the rest of the group header does.  The code sample attached earlier in this thread (silverlightapplication169.zip) produces the same behavior, so I attached a screenshot from it.

Is there a simple way to add a border to the bottom of this group indent cell?

Thanks,
Ben

Hello Ben,


Actually if you want to fill that space you should edit the template of GridViewGroupRow.
There you should change the elements named IconInnerBorder and respectively IconOuterBorder and set their BorderThickness property to the bottom in the preferred way when a GridViewGroupRow is Expanded. Attached is an example that demonstrates this approach.

If you need any additional information please let me know.

Kind regards,
