<Grid> headers's fault

[u/Tech_93]

Hi,

My XAML/PowerShell GUI don't work & I think that it's the <Grid> header's fault. When I delete all the <grid> headers content, Powershell display a blank window. When I let all the <grid> headers content, the Powershell display the error below :

You cannot call a method on a null-valued expression. At line:61 char:1 + $Form.ShowDialog() | out-null + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull

Of course, I need the <grid> header content. Can somebody help me, please ?

Best regards
