View 1 RepliesI having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0.
I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue.
I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked.
I have a TreeView menu populated from a SiteMapDataSource. The TreeView defaults to all nodes expanded, but the normal client side expand/collapse behaviour for the nodes is not working. I get one Javascript error in my Firebug console, being:
TreeView_ToggleNode is not defined
What could be causing this?
i have a databound treeview in asp.net. how can i expand the root node and have the rest of the tree nodes all colapsed?
View 1 RepliesI need to create a dynamically expanding div tag, and I am not too sure how to go about it. Basically, I have a bulleted list control, which will be inserted inside a div tag. The div tag's height is set to about 70px. When more than 5 list items are added to the bulleted list control, I want the div tag's height to expand to show the rest of the items. What I was thinking is when there are more than 5 list items, to have a little linkbutton with the word more, and to click on this button, which will then expand on the div tag.

View 2 RepliesI'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

The result is a web page that allows me to navigate down to individual music files within various folders. Beside each music file is a checkbox.What I want to do is select several files and then click a button that will move the selected files from their existing location to another location. I'm running into two problems. One, whenever I add any control that performs a postback, the treeview doesn't repopulate. Two, I don't know how to retreive the values of the checked checkboxes.

View 1 RepliesUpdates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.

the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).

I've run into a problem with expanding a dropdownlist when the client is IE6...The screen allows users to optionally specify search selection criteria from dropdown listboxes. Since there may be a large amount of selection data, the usage of which is optional, the selection dropdown lists are only populated on demand (i.e., when the user clicks on the listbox -- I use the OnMousedown event). This improves the overall performance of the system since most users will not use the optional search data, saving time since that data is not retrieved from the Web Services calls and not added to the lists.
After loading the list, I fire the OnClick event to simulate the user's mouse click and display the list items that were just added. For IE7 or IE8, firing the onclick event works perfectly to expand the list. However, this does not work for IE6 -- it requires a second and third click on the listbox to display the list. Note: replacing the fireEvent("onclick") call with alert() works with IE6 (haven't tried it with IE7) -- after clicking on the dialog, the list is displayed correctly. That's not a realistic option for production, but may shed some light on a possible solution.
