Set node value on View switch

[Jeffshex]

I know you can do code in the OnSwitchView event.
I'm trying to set 3 fields back to blank.
Is this done differently if I am using VBScript?

Thanks,
Jeff

Hi Jeff,

Here is some sample VBScript code to set 3 fields to an empty string:

Sub XDocument_OnSwitchView(eventObj)
Dim objField1
Dim objField2
Dim objField3

If XDocument.View.Name = "vwTest" Then
Set objField1 = XDocument.DOM.selectSingleNode("//my:myFields/my:field1")
Set objField2 = XDocument.DOM.selectSingleNode("//my:myFields/my:field2")
Set objField3 = XDocument.DOM.selectSingleNode("//my:myFields/my:field3")

objField1.text = ""
objField2.text = ""
objField3.text = ""
End If
End Sub

I hope this helps!

Here's the weird thing about it.
Let's say we are in form view 1 and switch to view 2 (which is used to look
up some things.)
If you don't set those few fields back to null and switch to view 1 and try
to lookup something again, nothing is returned until those fields are cleared
out.

Does that make sense?
I guess I need the the code to set values to null on exit of view 2.

Hopefully that is understandable.

Hi Jeff,

So does the code I previously provided resolve it for you?

Not 100% sure. It gets an "expected object" error and then points to the
line objFieldName.text = "" (I don't know why it doesn't like that line)
Anyways, it seems to run that code only when I switch from view 1 to view 2.
When I jump from view 2 back to view 1, those 3 fields don't clear out and
it causes view 1 to not work until you go back and clear em out.

Hope that explains it better.
Jeff

Hi Jeff,

So a couple of things:

- If you look at the code, the reason it only works for one view is because
of the view "test" I incorporated. If you want to execute the code
regardless of the view, then simply remove the test.

- If you are getting an "object expected" error then typically this means
the XPath to your control is not correct.

Scott,

I couldn't figure it out...so I just did it the poor man's way.
I put a button under those 3 fields that says "Switch to Main View"
Under that I have rules to set the value of those fields to ""
along with a switch views.
Pretty easy...yet it works.
