Question
Validating a page list size using the Validate rule
Hi
I have a read-only grid which gets populated by external source. On reviewing the contents, user makes a decision to move the process forward. Incase if the user tries to move the process forward with the empty grid, screen should show an error message. Basically I would like to have to a validate rule in the flowaction to evaluate the size of the page list sourcing the grid. Validate rule is not supporting this somehow.
My pagelist property name is Products and i have tried entering Products().ProductName and tried the sizeOfPropertyList by selected the 'expression evaluates to true' option.It dint work.
Is there any better way to validate the page list size when user tries to moves out of the screen with the empty grid?

Thank You Shekhar. Above is a way to throw error. I thought Validate rule can provide an option to verify the list size without mentioning any of the fields in it.
Hi,
There is a discussion on pxResultCount. Might be helpful for you.

Thank You.
Hi,
A field size validation rule can be created like this. Now in this scenario user is supposed to enter the values.
Now since you are fetching data from some place and then moving to other screen shouldn't change much with respect to the validation rule.
I have written a simple field validation rule for all three type of property. Let me know if its helpful or not
