Posted on by LsLee

the goal is to allow users to enter values into text input fields within a gallery based on a selected choice in a combo box. However, when users switch between different choices using a combo box, the entered values in the text inputs should be preserved and displayed if the user returns to a previously selected choices in the combo box.

Hi @LsLee ,

You can use AddColumns to add multiple columns for each choice and patch inputs to corresponding choice columns.

Assuming that Items of combo box is this.

["Choice1","Choice2"]

Step1.

OnStart of App or OnVisible of Screen.

ClearCollect(COL,AddColumns(DataSource,Choice1,"",Choice2,""))

Step2.

OnChange of TextInput.

Switch(ComboBox.Selected.Value,"Choice1",Patch(COL,ThisItem,{Choice1:Self.Text}),"Choice2",Patch(COL,ThisItem,{Choice2:Self.Text}))

Default of TextInput.

Switch(ComboBox.Selected.Value,"Choice1",ThisItem.Choice1,"Choice2",ThisItem.Choice2)

Step3.

It should have a column in your data source to save selected choice.

OnChange of Combo box.

Patch(COL,ThisItem,{Title:Self.Selected.Value})

DefaultSelecteItems of Combo box.

{Value:ThisItem.Title}

Best regards,

Rimmon

Thank you for the guidance.
Can the Powerapps also achieve this?
the entered values persist in the gallery even when the ComboBox filter is cleared

Hi @LsLee ,

You can add a condition in Switch function to set default value when combo box is cleared.

Something just like this.

Switch(ComboBox.Selected.Value,"Choice1",ThisItem.Choice1,"Choice2",ThisItem.Choice2,"","the entered values you want to keep")

The entered values for each choice is not lost, as the input value has already been saved to the corresponding column.

Best regards,

Rimmon
