OnPostBack I wish to know what are the selected categories. also, I need to give a spiciel ID number for each checkbox when data is binding.
I have a treeview on an ASP site that I populate from a DB using a Stored Proc that delivers XML. I am using an XML datasource that is loaded from the SP programmatically in the dadtasource's onload handler (if there is a way to load it from an SP declaratively, let me know). The treeview has its 'ShowCheckboxes' property set to "Leaf" (see code below) so that any leaf node can be checked.
The problem is this - I have a 'Checked' attribute in the leaf nodes of the XML (see below) that I would like to have databound to the treeview (I have databound the Name and ID attributes successfully) and I can't seem to find a way to do this. I also tried programmatically, but the treenode's dataitem property seems to have the value 'Nothing' even after the tree is databound.
How do I bind the 'Checked' attribute to the treeview's checkboxes? (Prefereably declaratively)
Example of XML here:
[Code]....
Note that nodes have Name and ID attributes, and Leaf nodes have Chacked attribute.
Here is the declaration of my treeview:

I'm currently writing a game review site in MVC 2. I'm having some problems both figuring out exactly what to use as my view models and how to display checkboxes in my form for a many-to-many relationship. My main models generated by EF4.
The biggest problem at the moment is trying to figure out how to create checkboxes for a game's platforms. There's a many-to-many relationship between games and platforms - each game can be available on a number of platforms (PS3, XBox 360, etc.), and each platform has a library of games. In my Edit view, I need to list all of the platforms and have the ones the current game is listed for checked. I have the following view model:
[Code]....
So, I need to list all of the view model's Platforms while putting a check mark in the GameData's platforms.
I need to create a selection table, i.e., a table with names and checkboxes.
When some checkboxes are selected, based on selections made on checkboxes i need to generate results(not from database), results are like different name of Is there some kind of architecture for this?
for example, we have name of columns as has legs, has feathers, has wings, can swim, carnivorous,herbivorous, etc
and based on selections i would say animal or bird or fish or amphibian, etc.

View 1 RepliesI am writing a programming using Tree View. I have created the Tree View object and have added a node for the root called Favorites. I want the user to be able to enter a value in a text box and once clicking on an add folder button, an event fires that takes the text that was entered in the textbox and creates a new node under the root node of favorites.
I am having a problem with my program in that the user is not able to click on the Favorites root note in order to create another node underneath of it. Favorites is simply displaying on the screen, but they cannot click on it to select it. What do I need to add so that the user can select the node to which they want to add a child node to?
Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I have a Repeater which populates a list of Checkbox controls and Label controls. But it doesn't seem like the checked state of the checkboxes is remembered in ViewState until AFTER the first postback.
Scenario: I have 5 items in my custom checkbox list. I select the first 3 and submit the form. The first 3 are no longer selected. I select items 1, 3 and 5 and submit again. After the page is loaded 1, 3 and 5 are still selected.
