How to manage control visibility in Canvas App?

Posted on by Dave Wi

Hello,

There is a Textbox1 and listbox1 control on the screen and I need to manage followings:

By default listbox1 should be visible false
when user type in Textbox1, then only listbox1 should be displayed, else it should be visible false.
when item is selected in the listbox1, listbox1 should be visible false.

Currently Listbox1.Visible = !IsBlank(Textbox1.Text) which only satisfies 1 and 2nd condition. How can achieve all above conditions to be executed?

Thanks,

Hi Dave,

the below-mentioned requirement. you can implement like that.

1. By Default List is Hidden - Condition Expression is - if(IsBlank(TextBox ),false,true).
2. if you need to Collect All Selected Value then you can use Button with Collection / On Select Event Collect into the Collection.
Like Below (Note - OnSelect Event You Need to Get Distinct Value if you Need to Save or Patch)

And again remove the text from Text Box.
The list is Hidden.

Please FInd the below Link for the Demo of the Test.
