I followed the sample here ProGuide Custom settings · Esri/arcgis-pro-sdk Wiki · GitHub and have added my own add-in settings to the backstage. I've binded several properties to the UI and it works great. I have a textbox where the user can browse to a folder where our company's data exists. If the user inputs an invalid folder I wanted to change the backcolor of the textbox and set the OK button to disabled until the input is fixed. A similar thing is done with the Layout options.
Ive looked in the community samples and looked at the Pro SDK and cant find anything. Where would I add my validation logic to mimic the existing Layout options?
I have attached bundle of ProjectSettingsView mvvm code of BackStage_PropertyPage sample from Esri ArcGIS Pro samples. It works
Ok I am able to bind my validation rules to the textbox. It works great! Thanks!.
But now am struggling how to get that result back to the ViewModel so I can update the IsValid of the page.
My XAML looks like this
<TextBox x:Name="txtLayerDir" TextWrapping="Wrap" VerticalAlignment="Top" Margin="10,86,36,0"> <TextBox.Text> <Binding Path="MyAppDataDir" UpdateSourceTrigger="PropertyChanged"> <Binding.ValidationRules> <ui:DataPathRule/> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox>
In the ViewModel I can initialize to False and I can see that works:
Protected Overrides Function InitializeAsync() As Task
'setup the initial validity of the Page MyBase.IsValid = False
Return Task.FromResult(0) End Function
But how do I process updates? Just cant seem to figure that one out.
You can disable OK button by setting Page IsValid property, like this:
base.IsValid = false;
Yes Im aware of the validation binding. Thank You. What I am asking is how we tap into the Pro Settings OK button to disable it when something is not valid.
Hi Abel,
This is the WPF stuff. Look here:
