Setting a Session Variable in one Grid and retrieving it in another

[psamuels56]

Hi. I hope you can help. I've been programming in Alpha for many years, but I've never used session variables. What I want to do is probably simple, but whatever I've tried hasn't worked:

Here's what I want to do: On a single screen, I have several Grids open (I designed this application more than 7 years ago). They are connected as Parent/Child, BUT the 2 grids where I want to share data are NOT directly connected (one grid is a child to a parent and the other grid is a child to a third grid which is a child of the same parent... I'm not sure that's relevant to what I'm trying to do here, but I thought it would be useful for you to know):

Here's what I want to do: I'd like the user to be able to click a row in Grid A and have a session variable set for one of the fields in that row. Then, I want the user to be able to double-click a field in Grid B and have the value of that session variable inserted. That seems like it would be the easiest way to move the data between the 2 grids.

In Grid A, here are 2 commands in the on-click function:
var1 = {dialog.object}.getvalue('G','TRUCKID',{grid.rowNumber});
alert(var1);

That works PERFECTLY! When I click the row, I get an alert with the TruckID of that row.

So, I tried this.
session.TruckID = {dialog.object}.getvalue('G','TRUCKID',{grid.rowNumber});

... thinking that would set a Session Variable called "TruckID" that I could recall in Grid B. But, it never worked. I don't believe the Session Variable was ever set, but since I've never used session variables, I'm not sure.

In Grid B's double-click event on a textbox, no matter what I tried, I could not insert the TruckID.

I hope this sounds easy to you and you can let me know how to get this working. I'd appreciate any help.

Thanks,
Phil

Session variables are server variables, so they cannot be set with client side javascript. That needs Xbasic such as session.TruckId = "truck1". Similarly, the same session variable in the other grid will need a callback to retreve the session variable.

In theory, you could set a state variable to the value of the session variable.
State variables work server side and client side.
