Hello I found a nother bug:
I added some code to support showing and hiding columns.
at first I add code to showall and hideall:

internal void HandleShowHideAllColumns(bool visible)
{
foreach (Column column in grid.Columns)
{
column.Visible = visible;
}
}

try this and u'll see that the hide works but when I hit show all again the rows are hidden in a weired way.

Itzik

There effectively seems to be a bug there... Thanks for reporting this. We'll try to fix this issue in an upcoming version.

FYI I am doing a similar thing, but rather than showing or hiding columns, I add and remove them and it works fine

<xcdg:DataGridControl Name="servicesList" ItemsSource="{Binding Path=Services}" AutoCreateColumns="False" ReadOnly="True" NavigationBehavior="RowOnly">

<xcdg:DataGridControl.Resources>
<syscollections:ArrayList x:Key="AdvancedColumns">
<xcdg:Column FieldName="Statistics.WhenLastPublished" Title="Last Published" DisplayMemberBinding="{Binding Path=Statistics.WhenLastPublished, Converter={StaticResource DateTimeConverter}}" Width="100" />
<xcdg:Column FieldName="Statistics.YieldSetCount" Title="Yield Sets" DisplayMemberBinding="{Binding Path=Statistics.YieldSetCount}" Width="100" />
<xcdg:Column FieldName="Statistics.WeightingSetCount" Title="Weighting Sets" DisplayMemberBinding="{Binding Path=Statistics.WeightingSetCount}" Width="100" />
<xcdg:Column FieldName="Statistics.PublishingSetCount" Title="Policies" DisplayMemberBinding="{Binding Path=Statistics.PublishingSetCount}" Width="100" />
<xcdg:Column FieldName="Statistics.LivePublishingSetCount" Title="Published or Live Policies" DisplayMemberBinding="{Binding Path=Statistics.LivePublishingSetCount}" Width="150" />
</syscollections:ArrayList>
</xcdg:DataGridControl.Resources>

<xcdg:DataGridControl.Columns>
<xcdg:Column FieldName="ServiceIdentifier.ServiceBrand" Title="Brand" DisplayMemberBinding="{Binding Path=ServiceIdentifier.ServiceBrand}" Width="70" />
<xcdg:Column FieldName="ServiceIdentifier.ServiceNumber" Title="Number" DisplayMemberBinding="{Binding Path=ServiceIdentifier.ServiceNumber}" Width="70" />
<xcdg:Column FieldName="Description" Title="Description" DisplayMemberBinding="{Binding Path=Description}" Width="300" />
<xcdg:Column FieldName="Statistics.WhenLastModified" Title="Last Modified" DisplayMemberBinding="{Binding Path=Statistics.WhenLastModified, Converter={StaticResource DateTimeConverter}}" Width="100" />
</xcdg:DataGridControl.Columns>
<xcdg:DataGridControl>

Then in the codebehind

ArrayList advancedColumns = (ArrayList) servicesList.FindResource("AdvancedColumns");

if ((bool) e.NewValue)
{
// Add the advanced columns to the grid
foreach (Column column in advancedColumns)
{
serviceList.servicesList.Columns.Add(column);
}
}
else
{
// Remove the advanced columns from the grid
foreach (Column column in advancedColumns)
{
serviceList.servicesList.Columns.Remove(column);
}
}

thanks

Hi,

 I am trying to bind the  IsChecked property of a checkbox to the Visible property of a column in the data grid.  This XAML doesn't seem to work.

<xcdg:Column FieldName="Freight" Visible="{Binding ElementName=chkBox, Path=IsChecked}" />

 Doesn't anyone know how to do something like this?

I am trying to do this as well and I just cannot get it to work. Is this a bug? Is the visibility being overridden sometime later after the binding?

 

Anyone? Is this not possible?

Do you have any binding errors in the output window?

Yes (now that I look)

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=IsChecked; DataItem=null; target element is 'Column' (HashCode=44247136); target property is 'Visible' (type 'Boolean')

Does this help at all? Is it a scope issue? The grid is inside a Tab Control but I have tested putting another checkbox in the tab and binding its checked state to the same source and that works ok!

 

This is normal behavior since columns are not in the visual tree. This post (http://www.drwpf.com/Blog/Default.aspx?tabid=36&EntryID=36) on Dr.Wpf explains why.

By "normal behavior" do you mean then that it is not possible?

Correct. This is not possible.

Hmmm. So can you give any hints on how to achieve this? Styles on the column, DataTriggers etc? I can change the Visible property in the code behind but I want it bound to the data.

It is not possible to style a column because it is not a FrameworkElement. Unfortunately, I do not have a solution to provide you with.
