Dropdown list

Dropdown list

Hi,

I have a dropdown list in Mathcad. I have sections in it and it calls in some of the required section properties under it.

Unfortunately whenever I close and reopen the file, the list jumps back to the very first item and forgets what I had chosen before.

I have tried to protect the area but didn't help.

Could anyone tell me how can I fix it to remember my choice?

Thanks in advance,

Viktoria

Unless you use web controls you may finde a solution here: Saving the state of controls.zip

Thank you!

I submitted this example to the old Mathcad Collaboratory a long time ago and it was featured in a Mathcad Express article.  I can't find the old article on-line any more, but here is the Mathcad file, updated for Mathcad 15, demonstrating how to create persistent controls using the metadata in the file.  I use this technique quite frequently for files that need to maintain their control states.

Hi Jeff,

I have tried to type into the script according to your guidance but got some error messages and gave up after all.

Anyway what I did at the end, just picked what I need from the listbox, found which element was it, then wrote this number back into the script  to the "If OnLoad Then

  ListBox.CurSel = " section.

Maybe later I will try again to set up your method, it is much sophisticated than mine

Thank you anyway!

Hi William,

Looks like Werner's and Jeff's answers may have helped you - excellent.

If one of those did solve your issue, would you please mark it as correct?  This will make the knowledge / solution easier to find.

Thanks for participating within PTC Community.

Best,

Toby
