Horizontal scrolling when filter returns no result

[JDB]

Hi,

I'm using a RadGridView with a lot of columns, which requires horizontal scrolling to see all the columns. But when a filter is applied to a column outside the view, and that filter returns no results (empty list), the view scrolls to the start and the horizontal scrollbar disappears. If that happens, I can't clear the filter because I can't scroll to the column the filter is set on.

I tried:

<telerik:RadGridView ScrollViewer.HorizontalScrollBarVisibility="Visible">
<!-- columns and stuff -->
</telerik:RadGridView>

But the scrollbar still disappears.

Is there some solution for this problem?

Thanks in advance.

I'm having a problem with both horizontal AND vertical scrollbars not appearing - I'm on a trial version that I am trying to justify the purchase of. Does the fix work for both H & V scrollbars?

[Nedyalko Nikolov]

Hello Allan,

Of course fix works well for both horizontal and vertical scroll bars.
You can open a support ticket and I'll send you latest internal binaries to check it out personally.

Don't hesitate to contact us if you have other questions.

Hello igal a,

You can download the latest internal builds from Your Account->Downloads->RadControls for WPF->Latest Internal Builds. The version of the latest internal build should be 2009.3.1116.

Let me know if I can be of further assistance.

i'm going to buy it in a week

so is there any workaround for the trial?

[Hristo]

Hi igal a,

We offer a trial version of our latest internal builds. They are available under Your Account->Downloads->Free Trials->RadControls for WPF->Latest Internal Build (Trial).

If you still have difficulties to download the LIB, please open a formal support ticket where I can attach the latest binaries.

it's not what i meant, your example fills the itemsource with one row,
what i meant is when the itemsource is null


i also tried to put this in the style:

 

        <Setter Property="ScrollViewer.CanContentScroll" Value="True" />
        <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Visible" />
        <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
        <Setter Property="GridView:GridViewScrollViewer.CanContentScroll" Value="True" />
        <Setter Property="GridView:GridViewScrollViewer.HorizontalScrollBarVisibility" Value="Visible" />
        <Setter Property="GridView:GridViewScrollViewer.VerticalScrollBarVisibility" Value="Auto" />

 

but it didn't helped


i think that the problem lies within the

 

GridViewScrollViewer.InvalidateScrollInfo()
or in the
GridViewScrollViewer.MeasureOverride(Size availableSize)

Hi,

The grid is bound to empty enumerable - you can check the code for more info.
