Script to assert values into numeric filter

#1

Hey, I’m trying to write a script for a button that will pull a value from a text box (value entered by user) and put it into either the upper or lower bound of a numeric range-number filter. However, I cannot find where those upper and lower bounds are in the object.

Anyone know where I can find them?

Thanks!

A range filter’s parameter value would be a RangeNumberValue type.

As such, the upper and lower value that are set in the filter control can be seen in this object through the upperBoundaryValue and lowerBoundaryValue properties respectively.

Thank you.

So… how do I find that?

This is the part I always struggle with. My filter is called upperFilter, so I tried…
upperFilter.control. but it’s not there
upperFilter.data doesn’t exist
etc etc.

I just don’t know how to read those pages of info and translate them into the property’s location in the object. What am I missing?

OK, I looked around and happened upon some code that grabs the parameter. And I can set the value. But the number displayed in the filter doesn’t change, nor does the table refresh based on the new value.

var view = this.parentView.control;
var param = view.getViewParameterByName(“upperFilterParameter”);
param.parameterValue.upperBoundaryValue = 2;

Heh, and I keep digging and digging and finally find someone else on a similar mission as I am:

param.refreshAllAdapters();

This did the trick. I guess the moral of the story is that if you wait long enough, I’ll eventually figure it out on my own lol :upside_down_face:

Glad to see you managed to work through it! For future reference, here’s a sample we have - in the code snippet, make you always include the invalidate and refresh calls after updating a view parameter.

viewParameter.invalidateParameterValueLastModifiedTime();
viewParameter.refreshAllAdapters();
