populating an MSFlexgrid

Posted on 2003-12-03

Take a look at the following code, basically all I'm doing is getting a session variable from another page and converting it to a standard variable. Then creating an array to populate an MSFlexGrid.

When I try to run the code as the page loads I get an error message Object Required G was not handled, (G is the name of my MSFlexGrid)

However, if I place this code in a sub, the page loads first and then I execute the code and it works fine - presumably because my MSFlexGrid (G) exists on the page, where as it doesn't in the earlier scenario.

How can I populate this grid when the page loads and remove the need for a click event.

Looking forward to your help.

Matt.

Good point, the array is created in the previous page and passed to this page as a string.

The value retvar contains what I want but the problem still stands of populating g, any ideas how I can do this.

I think that g does not exist when I try to populate it in the code above, how can I get around this.

Matt.

If the object is created in the last page, then it is also destroyed at the end of execution of the last page. You need quite simply to create G within this page you can pass values in string form but you will have to create it here

PS - You may want to avoid naming variables like you do, it is far easier for everybody (yourself included) if you try naming things like intLoopCount, grdMyFlexiGrid  - a's b's and z's are meaningless and make reading code difficult
