Good Day

I'm trying to create a slider and text input in a Gallery that works bi-directonially.

I have tried the solution here and here. The problem with these is that the variable used will update all sliders and all text inputs, not just the one item of the Gallery that I want.

In the example below, I want to be able to set either the text input or the slider for each individual item.

At the moment, I've set the text input's default value to the Slider's value. This does update the text input when I move the slider. But if I want to set the Slider's default value to match the text input's value, then I get a circular reference error.

Any help would be appreciated.

I managed to solve this by using Collections.

I changed the "OnChange" property of the slider to this:

If(
 IsEmpty(
 Filter(
 MyCollection,
 ItemID = Gallery1.Selected.ID
 )
 ),
 Collect(
 MyCollection,
 {
 ItemID: Gallery1.Selected.ID,
 Quantity: Slider1.Value
 }
 ),
 UpdateIf(
 MyCollection,
 ItemID = Gallery1.Selected.ID,
 {Quantity: Slider1.Value}
 )
)

And then set the "Default" property of the Slider to this:

LookUp(MyCollection, ItemID=ThisItem.ID, Quantity)

And then did a similar thing for the TextInput - "OnChange" is this:

If(
 IsEmpty(
 Filter(
 MyCollection,
 ItemID = Gallery1.Selected.ID
 )
 ),
 Collect(
 MyCollection,
 {
 ItemID: Gallery1.Selected.ID,
 Quantity: Value(TextInput1.Text)
 }
 ),
 UpdateIf(
 MyCollection,
 ItemID = Gallery1.Selected.ID,
 {Quantity: Value(TextInput1.Text)}
 )
)

And the "Default" property is this:

LookUp(MyCollection, ItemID=ThisItem.ID, Quantity)

Hope this helps someone.
