Building child controls on Design Time

[Pradeep Kumar C]

Hi ,
I am trying to create a custom control similar to datagrid.Grid contain
some thing like data column where i am able to add column during design time
using VS.NET 2003 collection editor , but on clicking the save button the
corresponding innercontrol is not return on the aspx page. But I can
instantiate the corresponding control details in the code behind page.

It will be appreciable if any body can give a solution for this.


Thanks and Regards,
Pradeep

Hi Pradeep,

Not sure what's your detailed code for the certain control. But I think you
can have a look at the TreeView control(IE WebControls)'s source code for
reference since the IE WebControl's code are all open source. The TreeView
has a "Nodes" member collection wihch may be similiar to your question.
You can download the IE WebControl's source at [url]http://www.asp.net[/url]

also, here are some other tech articles on asp.net web control dev and
designtime support:
