Without looking it in depth I’m not sure. I tend to use XCeed’s DataGrid (free version no longer available though).

HI
thanks for your code.
but I have a problem is that when the System.Globalization.CultureInfo changed ,

“double percentage = double.Parse(widthParam.Substring(0, widthParam.Length – 1));”

will not parse correctly.if we change the current CultureInfo to Polish form.we could not get the respect result

how to handle this problem ?

thank you

Thanks, that looks to be a more robust solution.

It is possible to have this update when the GridView is resized (i.e. when the window is resized thus increasing the GridView)?

My code is identical more or less. The header in my ListView is:

<ListView x:Name="lstResources" Grid.Row="4" Grid.Column="0" Grid.ColumnSpan="2" GridViewColumnHeader.Click="OnColumnHeaderClick"
	  SelectionMode="Single" ItemsSource="{Binding}" SelectedValuePath="resourceid">

To post code BTW, enclose it in pre tags.

ooops, sorry but the xaml code seems to be detected as html code. here we go again(this time with [] instead): [ListView Name="fp_userList" Margin="10,0,10,10" SelectionMode="Single" ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionChanged="fp_userList_SelectionChanged"] [ListView.View] [GridView ] [GridViewColumn Header="User" Width="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type ListView}},Converter={StaticResource WidthConverter}}"/] [/GridView] [/ListView.View] [/ListView]

Hey,

thanks for your response, but as “value” is always null, the check for null just lets the method return null after the first line…
Perhaps we didn’t implement our listview in the correct way…here´s one of the listviews:

The “WidthConverter” Resource is also set at the beginning of the xaml file.

Do we have to set any attributes to the listview?

Thanks for your help!!!!

I didn’t experience that problem, but I’ve amended the sample with a check for null. Try using that. The value parameter should be the ListView, but if the Window/Control hasn’t loaded yet that might cause an exception.

Hi,
nice code, but it doesn’t work in my project.
I think i’ve a problem with this line:
{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type ListView}}
because the variable “object value” in the method is always null.

Can you post a sample xaml code please?
