In my webpage using treeview control in update panel. The treeview control sometimes working properly and somtimes not working. I heard that treeview contol is not compatability with ajax update panels. Is there any alternate control for treeview control or how can I use treeview control in update panels properly..
View 1 RepliesPeriodically 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 treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

View 1 RepliesQuery 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?

I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used
ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.

i want to build a datagrid bound to a datatable with several columns. One column has only a dropdownlist with the number of the rows in the datatable.
Here a samplescreenshot:

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

The page posts, when you click the update button, but the data never changes / updates.
I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
