Problem with columnspan when hidding columns

[hightow]

I have a gridview containing 2 header-rows. The first row (CommonHeader) displays years, the second row (GridViewDataColumn) displays quarters 1 to 4.
Each column in first row is set up with a columnspan of 4 in the xaml, and the appropriate startcolumnindex.
xaml looks something like this:
...

<local:CommonHeader StartColumnIndex="1" ColumnSpan="4" >

<TextBlock Text="2008" />
</local:CommonHeader>

<local:CommonHeader StartColumnIndex="5" ColumnSpan="4" >

<TextBlock Text="2009" />
</local:CommonHeader>

...

<telerik:GridViewDataColumn Header="Q1"  />

<telerik:GridViewDataColumn Header="Q2"  />

<telerik:GridViewDataColumn Header="Q3"  />

<telerik:GridViewDataColumn Header="Q4"  />

 

<telerik:GridViewDataColumn Header="Q1"  />

<telerik:GridViewDataColumn Header="Q2"  />

<telerik:GridViewDataColumn Header="Q3"  />

<telerik:GridViewDataColumn Header="Q4"  />
...


In addition I have attached a contextmenu on rightclick on the columns, giving the option to show/hide columns.

The problem with this is the columnspan of the "CommonHeader"-row. Do I have to write code for updating the columnspan when I show/hide columns, or is there a property I can set that fixes this for me.

Hello Helgrim,

 Yes, you would need to manually update the the ColumnSpan property.
