I am creating and configuring multiple TreeView controls programmatically:
foreach (DataRow dr in ds.Tables[0].Rows) {
TreeView TV = new TreeView();
TreeNode newNode = new TreeNode();
[code]...
somewhere on the net I found very useful example of programatically databainding the treeview control (code blow). I use this treeview as menu bar in my masterpage. It works fine but with one exception: when I click the node of this treeview I'm redirected to the correct page but after page is reloaded my treeview is collapsed and node I chose just before is not highlighted. What to do to correct this problem. Do you know better examples of programatically databainding of the treeview control? Maybe it will be better to bind data to the sitemapdatasource and next to the treeview. Then I shouldn't have to worried about this?

View 1 RepliesI am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

i want to create a tree view for displaying folder hierarchy

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 a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.
View 3 Replieswhat the best way to create text boxes in my loop here so that the IDs are unique instead of just "TextBox" for all of them. I need to add up the Price based on the Price per unit and the Quantity.
My items are loaded from a database so there could be any number of them, so I need to generate the fields on the fly. I was thinking maybe an array of fields could be used like in a form application, or is this not the right way to go?

View 2 RepliesI hope to get some guidance on how to create reorder lists programmatically because of the situation described below.I have a page where I want to have a toDo Iist for each of several (typically 10) milestone categories. I can think of 3 options.I don't know in advance how many 'active' categories there will be but I there is a known fixed total of about 20 categories, of which from 1 to 20 may be 'active'1. Have one Master ReOrderList And Then Nest the Category ReorderLists Inside 2. Create the reorderlists programmatically.3. Brute force approach. Hardcode all 20 reorderlists and their associated sqldatasources, and then set visibilitydepending on which category is active. This approach is the simplest but has the disadvantage of too muchrepetitive code and the reorder lists would be in a fixed order, when I really want them to match the category order.
View 3 RepliesI want to programatically create a directory on the server using ASP.NET.
I have done this using System.IO's Directory.CreateDirctory. however, the newly created folder is not accessible in the code.
after searching a bit, I came to know that the newly create folder is not included the project and hence not accessible.
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].....

View 3 RepliesI have a dataset with 3 tables that are inner joined. Thsi dataset is connected to an object datasource which is connected to a gridview. So at runtime it displays data from the database. The problem is when I click on a save button to add information to the database it throughs me an error saying Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. But if i have two tables in my dataset it works 100%. But the problem i need that 3 tables in order to pull the required information. And if i populate the gridview using code to select the information from the database and insert information it also works 100%.

I have a control that displays a list of comments. The comments are created in a loop. The problem is that I want to put a LinkButton at the end of each comment and change the CommanArgument of each button to the ID of the current comment.
When I put the Linkbutton in the CreateChildControls method and then add the CommandArgument in the Render loop, the button works, but the argument is blank. When I put the code that's in the CreateChildControls method inside of the loop, I don't get an error, but nothing happens when the button is clicked.

I am programmatically exporting multiple reports to a pdf via the ssrs web services using C#.Net. It exports a single report just fine, I was wondering if there was a way to export multiple reports?
