Conditional visibility and clear text box

(0) Share

Posted on by AnnetteM

I have a screen that has a combobox with a yes/no choice. If the value of the combobox is "Yes", then I want another text control to be visible and required. This is working fine. However, when someone changes the combobox to "No" from Yes, I want the other text control to clear its contents and then hide.

The visible part is working correctly, but I can not get the contents of the text control to clear out when the combobox is changed to No.

For example, I have a combo box of "Is someone else completing the work?". The answer is yes or no. If yes is selected, another control called "Who is completing the work" appears. When someone goes back and changes "Is someone else completing the work?" to a No, I want the other text control to clear because the last saved response is no longer valid and the text control should be blank.

Any suggestions?

The visible part is easy, just have the text controls Visible property Combobox.Selected.Value = "Yes"

To clear the box, you can use the OnChange property of the combobox: Reset(TextInput.Text) and make the Default property of the TextInput Box: Blank()

I am not getting this process to work. Although the field in the datacard appears to be empty, the data in the underlying SharePoint list is not committing the blank value to the column. I still see the text when it was a Yes. So, it appears the only thing this changes is what appears in the column in the form, not the datasource. Any ideas?

Check the Update property of the card containing the textbox control and make sure it is referencing the correct control. If that doesn't work, the card may be corrupted and you can delete it and add it in again to see if it works right.

If the combo is yes, the text control is visible and required so I can add data. When I submit the form, it writes to the SharePoint list the yes value for the combo and all the text I added in the Text control, however the text control on the screen now appears blank -- despite the SharePoint list showing the value. Of course, when I change the combo to no, the text control is hidden, contents written to blank and when I submit the form, the datasource it reflects No in the combo box and a blank value in the text control.

So the challenge is showing the contents of the text control when the value is yes. The datasource has it. I checked the default property of the text control and it is Blank() (used to be parent.default). The default of the datacard containing the text control is referencing the correct control.
