Posted on by MIA27

I am trying to apply the below code on the Button DisplayMode, But getting error of Enum

If(And(CountRows(GalleryCartOrder.AllItems)>=1,Sum(GalleryCartOrder.AllItems, Value(LineTotalAmt.Text)) > 0),

DisplayMode=DisplayMode.Edit,

DisplayMode=DisplayMode.Disabled)

Please advise what correction can be done to get the result as required.

Try removing the DisplayMode= from the two possible outcomes of the If. You are setting the value of the property because you are in the property. So you don't need to say what the values are applied to.

It worked in the test screen.
But when applied the actual screen, where I want if the 4 criteria matches then only Edit mode else disabled mode.
The below does not bring error but all the time it remains in edit mode

If(
And(
CountRows(GalleryCartOrder.AllItems)>=1, //must have item in the gallery
Sum(GalleryCartOrder.AllItems, Value(LineTotalAmt.Text)) > 0, //must have value as user should not select 0 qty
!IsBlank(TextBox2_21), // this text box has important ref, so should not be blank
!IsBlank(DatePicker1_7) //date field should not be blank
),
DisplayMode.Edit,
DisplayMode.Disabled
)

No error, but all time it remain in edit mode.

Please guide

Try removing all but one of the conditions and make sure that one will do both edit and disabled. Then add them back in one at a time. That should tell you which one is causing the problem. Otherwise it al looks right to me.

I test with only.

If(
!IsBlank(TextBox2_21),
DisplayMode.Edit,
DisplayMode.Disabled
)

Found the issue , if I manually remove !, then it work and put !, the effect on the screen shows.
But the same when in actual I type and delete it has no effect on the displaymode.
While means it does make the impact of IsBlank .

can we use other option like empty or Len function to test

pls. guide

Instead of referencing the control you need to reference the value of the control. Try the following instead

If( !IsBlank(TextBox2_21.Text), DisplayMode.Edit, DisplayMode.Disabled )
