Web Forms :: Creating TreeView With Loading Image?
Oct 17, 2010
I have created one treeView which is loading node dynamically (populateondemand ). its working perfectly fine. But I want to show loading when its populating node from client view.
Note : - Only on click of image of the Tree view should display loading ..
I have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
i have developed my asp.net application along wih crystal report .... i need to show loading image on ever client and server side request .... (i.e) like when ever IE progress bar get loading i want to show my gif loading ... after IE progress bar finish its loading, my gif loading image should disappear .
I am using a master page with a treeview control. I have 2 other pages Summary.aspx and Home.aspx
I want the Summary page to be loaded when I run the application but afterwards I want to load the Home.aspx page based on the selected Node change event of the treeview control.
I have placed the treeview control in master page because it has to remian the same for all my pages.
Did I do something wrong? The problem is I am not able to load the pages based on events occuring for Tree view control.
I am experiencing an issue with the TreeView control when loading new pages. It is databound to web.sitemap, but when loading a new page, it does not select the node of the current page, just resets it to the root. THe new page loads fine, just not preserving the current navigation in the tree view.

I am creating a PDF template file and I will want to use that to create other files. I have been looking around and found the following code:
[Code]....
The problem is that pdfreader, pdfstamper, acroreader are underlined and it says it is not declared so I couldn't test it, I wasn't sure what I had to import in order for it to work. In addition, if you have any other way that is easier to use let me know.
I am trying to create a TreeView nested structure with the use of self referencing table fields. Here is a simple example:
Category 1 Product 1 Toy 1 Toy 2 Product 2 Toy 3 Toy 4
more categories.. The database table has a single table called "Category". The ParentCategoryId points to the Category which is the parent. So, for the Category 1 the ParentCategoryId is null since it is parent. For Product 1 the ParentCategoryId is that of the Category 1 id and for Toy 1 the ParentCategoryId is that for the Product 1 id.
I am using the following code but it does not generate the TreeView (ASP.NET) successfully.
public void BuildTree(List<Category> categories, TreeNode treeNode) { if (treeNode == null) return;[code].....
I have a question that is very simple to answer, I have a treeview control populated by a sitemap file, what I want to do is to assign a different image to each node/leaf of the control, let me explain a little bit more, this what I have in my sitemap file:
[Code]....
So I know that a different image can be placed for root, parent, leaf and node on the code, but I want a different image for each leaf in the treeview... I know that the easy way to do what I want is to edit/add nodes in the control BUT I populated the control from a sitemap file, so is there a way to put a different image in each leaf of a treeview control being populated from a sitemap file?

If I have a DataTable (in-memory) read by my C# program from a flat file, and I want to create it as a new table in a SQL Server database... what is the simplest way to do that?
It seems like something like SqlBulkCopy with an option to create a new destination SQL server table would be on my line of thinking, but I dont see a way.

Here's a nice one for a Pro to bite into I have a web form that generates a set of reports including asp chart controls. Clicking on the black title loads the report section into the ajax enabled panel below it. Beautiful! Two Problems though: Sometimes, when the ajax is loading the next report section, all the other charts on the page flicker and sometimes even show a red x (the image disappears). They can then reappear again when another chart loads! 2nd Problem: If I use the html-to-pdf converter, I tell all the panels to bind to the data source (they are repeaters) on page load and show content. I Then convert the resulting datastream to PDF. All the other images on the page load, but the ones for the charts don't. I have looked at the generated code, and they are all linked fine to the correct address of the site and the chart generator url. A sample image of the working page is below:
