Using Custom EditForm in ASPxTreeList
I'm Using ASPxTreelist to Show Tree of Levels:

list.PNG:[URL=http://imageupload.org/en/file/222249/list.png.html][IMG]http://imageupload.org/thumb/thumb_222249.png[/IMG][/URL]

Then Depending on the selection in the TreeList the Data on the GradView will be updated:

zones.PNG:[URL=http://imageupload.org/en/file/222250/zones.png.html][IMG]http://imageupload.org/thumb/thumb_222250.png[/IMG][/URL]

TreeList and GradView are Reading Data from different tables in DB, 
the thing is: 
when needs to create new Zone, user will click on "New Zone" link on the TreeList then a new form will come:

update.PNG:[URL=http://www.imageupload.org/en/file/222251/update.png.html][IMG]http://imageupload.org/thumb/thumb_222251.png[/IMG][/URL]

this form is EditForm from TreeList using Template form :

     <Templates>
        <EditForm>
....

When Clicking on "Create" button in that form I need to create new row in DB at Zone Table (which actually the table that gradview is reading from) 

but I cant access to the controls in that form (textBoxes), also I wasn't able to set default values in that form too ( Default should come from the TreeList (like Level Name))

Anyone can help please,
Thanks,
