Rowheader

[Andi]

Hi there,

is it possible to write something into the RowHeader?
I need to have a grid looking like that in my attachment.

Hello Andi,

 You can easily do this. You just need to tweak GridViewRow's template a bit. When you extract the XAML in Blend, look for a Border with x:Name="PART_IndicatorPresenter". You can place anything you wish in it.

Is it possible to do this by runtime out of the C#-Code?

[Yavor Georgiev]

Hello Andi,

 You can try something like:

var border = row.ChildrenOfType<Border>().Where(b => b.Name == "PART_IndicatorPresenter").FirstOrDefault();

However, this can play merry hell with virtualization and can introduce numerous issues. I still strongly recommend the templating approach.

ok, thank you.

Ok, I've tried out differrent things but they all does not satisfy me.
Now I take the first column as read only, so I don't need to write into the Rowheader and I don't need the Rowheader. Is there a way to blank the Rowheader out?

Hi,

 You can set RowIndicatorVisibility="Collapsed" to hide this. 

All the best,

Great, thank you

I've made a new template for GridViewRow, but now I have an alignment problem (see image).

Here's the new indicator presenter in the new GridViewRow ControlTemplate:

<Border
    x:Name="PART_IndicatorPresenter"
    Background="{StaticResource GridView_HeaderBackground}"
    BorderThickness="0"
    Grid.Column="0"
    Grid.RowSpan="3"
    VerticalAlignment="Stretch"
    Visibility="{TemplateBinding RowIndicatorVisibility}"
    telerik:SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical"
    >
    <Grid>
        <TextBlock
            Foreground="{StaticResource GridView_HeaderForeground}"
            Text="{Binding EmployeeName}"
            />
    </Grid>
</Border>

 
How can I make the column headers aligned with their cells? Do I need to just set a fixed width on the border and match it in another template for the column headers (if so, where is that)?

I'd rather make the width of the row header auto-sized if possible, but I imagine that might not work well with row virtualization?

Ah, I bet I have to choose a fixed width and make sure it matches with the width of the indicator presenter in the ControlTemplate for GridViewHeaderRow. I'll give that a shot. Please let me know if you have anything to add. Thanks!
