Web Forms :: How To Take The Treeview's Selectednode And Then Search Control From The Database
Dec 20, 2010
I want to take the treeview's selectednode and then search control from the database for that particular node and then bind it in gridview column dynamically.
The problem is like i am not able to get treeviews selected node in OnInit method and if If i bind it in page load or anyother i am able to get treeview selected node but i cant create dynamic columns at that time using template handler.
How can i get the treeviews selected node or what is the option to bind usercontrol in gridview column dynamically without template handler.

I have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.

I have a simple Treeview on my web page. I am using ASP.Net 3.5. I have 2 parent nodes and then some child nodes for each parent when expanded. I want my 2 parent nodes to align up to the left. And I want the child nodes to be idented under the parent and all aligned to the left. Presently, it seems like everything is aligned in the center. It seems odd that there is not a horizontal alignment proprty. Or am I just not seeing it?
