Can I force an error/warning, when a "select in field" does not select any data?

Can I force an error/warning, when a "select in field" does not select any data?

I have a button that selects an amount of days.

The amount of days is in a small list.

I like to press the button and do a subselect based on the amount of days.

In principal it works, but if there is no selection match, it shows all the data.

I would like to indicate that no records where found for the select.

Thanks.

Hi,

Try using the function

GetSelectedCount(FieldName)

returns > 0  when any values are selected.

Use this in If condition like this

If(GetSelectedCount(FieldName) > 0, 1, 0)

Jagan.

Hi,

Another option to what Jagan says is to use a conditional so the button will only appear when some selection is done in the field "Days", so there is no possible error, since the user will not see the button until he makes a selection in the fiedl "Days". Go to the button properties, Layout tab, set Show to Conditional and write the following expression:

GetSelectedCount(Days) = 1

That means that the button will only show up when there is only one day selected in the field Days.

Hope that helps.

Thanks.

I now have a text box, which only shows when my selection on days does not return a value.
