[Solved] Silverlight GridView RowDetail Issue

[Suraj Batra]

Is there any way to hide (Silverlight) grid's row while we are displying its Details i.e. as soon as row is selected, its details become visible but grid row (which is just selected) itself is hided.

Hello Suraj Batra,

This might be possible, but it will not be simple. You will need to edit the GridViewRow template and modify its Selected visual state. You should modify the visual state to hide the all the parts of the row that you do not want to see when the row is selected.

Hi Ross,

In my code I tried to set the visibility dependency property of GridViewRow's template to collapsed using the following line of code.
template.SetValue(VisibilityProperty, Visibility.Collapsed);
This line throws Catastrophic error at runtime.

Can you please provide some sort of code snippet for modifying the visual state (as mentioned in your reply).

Thank You,
Suraj Batra

Hello Suraj Batra,

Please find attached a sample which hides the row when selected and shows the row details instead.

Hi Kalin,

I used the code provided by you. I faced problems in using that code. First, the "GridLineWidthToThicknessConverter" is not available in following namespace

xmlns

 

:grid="clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView"

The other problem occurs when I run the application (after making changes, as specified in your sample code). Following exception is thrown when Usercontrol is being rendered (the usercontrol which contains these changes). Following is the exception stack trace

Error HRESULT E_FAIL has been returned from a call to a COM component.
   at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
   at MS.Internal.XcpImports.UIElement_Measure(UIElement element, Size availableSize)
   at System.Windows.UIElement.Measure(Size availableSize)
   at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride(Size constraint)
   at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

I googled this issue but couldn't found anything useful on this issue.

Thank You,
Suraj Batra

Hi Suraj Batra,

The sample I have sent you uses our latest internal build binaries. Could you please update to that version and tell me if you are still getting the error.
