[thabet084]

Hi all,


I create a map using Maestro .
I create a layout using Maestro then fill Initial task in taskpane with "Management.aspx" that contains ChechBoxList
I show map in using AjaxViewer in "map.aspx" in .NET
All is done correctly

Problem
In .NET
I need in "management.aspx" to get userName(TextBox) from "map.aspx"
"management.aspx" is showing as a component now at "map.aspx".
 How can I access map.aspx from management.aspx?or
How can I access map from layout?

I wish to show my problem in clear
