Mar 22, 2011

the tree structures(nodes and sub nodes) calls from the database and it expand to the screen using above coding...

I am building a class in which a GridView is created programmatically.I understand the need to fire the GridView_PageIndexChanging sub (no problems when coding the GridView declaratively).But when I build the GridView programmatically, I get the error:The GridView '' fired event PageIndexChanging which wasn't handled.How do I programmatically handle the PageIndexChanging event (code snippets in VB please)?
I've got a label in the item template tag of the datalist control. The label is bound to an integer column in the data source.
What I want to achieve is to retrieve the number from that label and change its text according to what number is retrieved.
i.e. if number retrieved = 1 then
lbl.text = "SomeText"
My problem is that I don't know how to code that label as it is found in the <ItemTemplate> of the datalist and intellisense cannot identify the label.
Is it possible for me to code that label using code behind? or is there any other way to do this?
If I have the ListView on a mode which only displays data (no editing or inserting), how do I reference data in a list view item using the code behind?
In other controls I have used e.Items and e.Values, but I can't seem to work out how to do it in the listview.
For example if I wanted to set the image based on a database column (I know I can do this in the HTML but just for the purpose of the example, what would I put in place of the *** below:
I am trying to implement server side paging with gridview using coding by DAL and BOL concept.But the Problem is with the Gridview page index.As the No of rows retrived are equal to page size and hence I am not able to genearate pager information .I cannot use object data source as i have 2 generate this on some event by passing some arguments like button clickPlease let me know how can i resolve it.Can i use datapager,Or do i need 2 create custom hyperlinks or any alternative to display gridview page index.

I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview> <row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/> </ITReview> <ITReview> <row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/> </ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
i am developing a tree view component which should be data driven and amendable instead default layout provided by .net can we change that proper hierarchial structure like organization chart is there any chance to provide with an hyperlink to redirect other page or content view control below to display the content related to it.
Is it possible to get the unique URL of an expanded treeview node? I need to be able to send the URL to someone and he should be able to navigate to that particualr node from the URL.. so I guess I need to somehow use a query string with the treeview control?
I've got a treeview inside an updatepanel. Currently I'm developing on a dev server through a remote connection, when I view the page from the dev server itself, it works. The expand/collapse images display fine. When I view the page from my machine's browser (same url, same browser) it doesn't display the images.
I've added custom images using the CollapseImageUrl/ExpandImageUrl properties, again it works from the server, but not from my machine. The actual rendered html differs. The page also contains some asp:Image controls which work fine in both browsers.
I have a treeview with EnableClientScript=true. It is not in an update panel. It works fine on my local machine but when I place on server, I get a WebResource.axd error when I try to expand the treeview. If I set EnableClientScript=false, it works fine. I need to have it set to true. Is this a bug?
