Count selected rows in a list

[Scott B]

Hi All -

This is another one of those "should be pretty simple" questions, but I am drawing a complete blank on how to do it (simply that is... can come up with a few convoluted ways, if necessary):

Background:

Simple list control with one field;
Based on SQL data;
List is in "Multi-select mode" whereas when a user clicks (single clicks) a row, that row becomes selected. User can choose as many or as few rows as they'd like.

Problem:
I need to create a simple control (could be a static text control) which contains the count of SELECTED records in the list control and updates as row are selected. The later part (the update) I can handle, but the first part is eluding me.

Thanks!

Should this post be in this forum section? Is this just about the List Control?

Based on your use of a TextBox Control... then... where ever you're processing the List selection... e.g. onClick, onSelect, then add this code...

{dialog.Object}.setValue('listCnt',this.selection.length);

"this" is the List object when processing stuff within the List Control.
.selection is a property of the List Control... which is an array of selected rows.
Get the length of the array and perform a .setValue to the TextBox control.

Thanks so much David. That worked perfectly. Not sure about the correct forum for this post. Happy to move it (if I can) and if its confusing where it is.
