Unsaved changes Popup

I have a label that is visible (unsaved changes warning) when changes are made to text box. Popup works fine, but if I delete the changes I have made in a text box, the warning popup stays visible. Is it possible to detect if contents of a textbox was set back in the original state?

 

Label.visible = NeedsSaved3

TextBox.OnChange = Set(NeedsSaved3, true)

Button that saves changes, OnSelect= Set(NeedsSaved3, false)

Add on another IF in the OnChange, if Self.Text = ThisItem.Description, Set(NeedsSaved3,false)

So you already have one mechanism for the identification of changes from the Unsaved property of the form.

The gallery would need to have one put into it.

How I accomplish this usually is based on what I originally mentioned of checking the textinput to the underlying record.  You will not be able to set a variable for this as each row needs its own identification.

 

I do not know your layout for your gallery, but I will provide a scenario where there are two textinput controls in the gallery and two underlying columns in your items datasource.

 

So, let's say there is a Title and a Description column in your Gallery and there is a textinput for each.

TextInput1 would have a Default property of ThisItem.Title and TextInput2 would have a Default of ThisItem.Description

Place a toggle control (named tglChanges) IN your gallery.  Set the Default property to : 

!(ThisItem.Title = TextInput1.Text) ||
!(ThisItem.Description = TextInput2.Text)

 

Now, in your label Visible property for the changes notification:

yourForm.Unsaved ||
(CountRows(Filter(yourGallery.AllItems, tglChanges.Value))>0)

Your label will now be visible if there are changes in the form or in the gallery.

 

Adapt the above to your scenario and you should have what you need.

What is the Default property of the Textbox?

Typically this is done with a comparison rather than a variable.

i.e.  the Visible property of your Label - theDefaultPropertyValue <> theTextBox.Text

This will set the label visible if the value is changed.

I hope this is helpful for you.

In the OnChange for the text box, If Self.Text is Blank, Set(NeedsSaved3, false).

Default of TextBox is ThisItem.Description . Description is column from datasource.

 

ThisItem.Description cant be added to Visible of label.

This works.

But if I put this on multiple text boxes, and I change 2 of them, and then change only 1 to the original text, warning goes away, even if the second textbox is still left changed.

 

My code for OnChange on textbox is now like this:

 

Set(NeedsSaved3, true);
If( Self.Text = ThisItem.Description, Set(NeedsSaved3,false))

You need to compare on the original value to the textbox value.  Variables will be a bit clunky to deal with as you are seeing.

Out of curiosity, is this in an EditForm?  If so, then the form already provides a mechanism for this.

In that case you'll have to check all of them.

If ( Self.Text = ThisItem.Description || OtherTextBox.Text =  xxx || etc. etc., Set(NeedsSaved3, false))  

Depending on how many you are dealing with there could be a more elegant solution.

@RandyHayes you referring to the Form.Unsaved flag?  Will it show unsaved if the text has been changed but ultimately changed back to what it was originally or not show the unsaved flag if it matches?

Yes, the unsaved will be true if there are changes.  If a user returns a value to its original value, the unsaved will be false.
