Posted on by Community Power Pla... Microsoft Employee

Hi All,

I am currently in the process to build a request form for my organization and i want to plug in some validations in the form. My data source is SharePoint Custom List. Below are my requirements:

Length validation for a text field : Restrict user to enter more than 15-20 characters in the text field. if they enter more than that I want the a display message stating enter maximum 15 characters and the save button should get disabled.
Date validation : if the user enters the date manually and not by selecting the date picker and if the date entered is wrong then it should also state a display message saying date entered is wrong and the save button should get disabled.

Thanks in advance!

Hi @Anonymous ,

Character Validation - on the OnChange of the Text box

If( Len(Self.Text)>15, Notify("Only 15 Characters allowed",NotificationType.Error) )

On the DisplayMode of the button

If( Len(YourTextBoxName.Text)>15, DisplayMode.Disabled, DisplayMode.Edit )

For the second one, set the IsEditable of the Date Picker to false.
