Does anyone know a way to limit the amount of text that is displayed by the Treeview control for a node?
I know there is a property to warp the text but I want to perhaps limit the text size to say 20 characrters?
I've applied this code from [URL]
and it is working fine except for updating TreeView after Insert/Update/Delete.

In my webpage using treeview control in update panel. The treeview control sometimes working properly and somtimes not working.

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've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?
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?

View 3 RepliesThe image is not getting displayed on the page if it is called through the routing engine, and the image is displayed on the same page if the page is directly called (explicitly appending .aspx).
Only those image which are set using <img> tag are not displayed whereas the ones whose value is grabbed using the routed url and into the <asp:Image> tag are dislplayed properly.

I'm sure you've seen sites that display a portion of the available text in a limited space followed by an ellipsis or a [more] link. That's what I need to do. The text is in a database field, and includes carriage returns and line feeds. I can't just count the number of characters. How can I only display the text that will fit in a defined space? I've tried using a panel control with the height defined. I've also tried a div with the height defined. Neither has worked. How is this done?
