I'm coding an Webpage in VS.NET 2010[C#] that scans the Serial Number of Product into a Treeview in a Work Order > Box > Product hierarchy.
What I wanted to do was to use the following to Remove the ChildNodes:
//Use the GetEnumerator method to create an enumerator that contains the root node data.
IEnumerator nodeEnumerator = myTreeView.CheckedNodes.GetEnumerator();
// Iterate through the enumerator to display the root nodes.
while (nodeEnumerator.MoveNext())
{
/In here I would like to Remove the TreeNode
//MessageBox(((TreeNode)(nodeEnumerator.Current)).Text);
}
}
else
{
MessageBox("The TreeView control does not have any nodes.");
}
I want to add, edit(update) and delete a node from a treeview. These all opeartion must be performed on the treeview itself.

View 1 RepliesIs there a way to add/delete/update the default classes (for instance AspNet-Menu-WithChildren,AspNet-Menu-NonLink ) of the html generated by the asp.net menu or treeview control? I am using CSSAdapters so the menu control renders in a list format instead of table format.
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.

I am using treeview to display records from 4-5 SQL Tables. Currently I am using 4-5 different stored procedures to retrieve data based on a dropdownlist value.The tree is loaded everytime the value in the dropdownlist is changed by the user.
Is there a faster way to load treeview as everytime a new selection is made, the treeview is binded again. Or is there any way I can optimize the actions I am performing now to bind the treeview?
i would like to add images for a tree view like for root node one image and for child node other like that i would like to add different images for nodes..
View 1 RepliesI am using Tree view to display Categories & SubCategories under it. It's working fine. to create a Tree View I had used,
http://aspalliance.com/732.
Problem is that I want my TreeView to be expanded. How can one do that? Moreover, From another page when I click a Product, I want that in treeView that Category(under which Product falls), should be expanded & node(ie selected Product) should be highlighted.
I am using treeview for all of the links that I have created in my Web.sitemap folder. However, I was wondering if there was a way that I could automatically logout after pressing the logout link in the treeview.
I've tried inserting the following code in the logout link within the code behind file :
protected void Page_Load(object sender, EventArgs e)
I have a small problem encountered on using Treeview. I have Two pages on the sample. On the first page you can see a button that says "Add Category" and a grid that displays all the previously added categories (coming from a sql db). Upon clicking the "Add Category" button here comes the second page. On that page, we can see a two radio button,a textbox and a submit button. The first radio button says "Add new category", then the second radio says "Add a sub category on the existing category" which shows up the treeview upon clicking. Upon entering the new category and clicking submit, it will return on the First Page and you can see the on the grid the newly added category. Upon adding again and clicking the "add a sub category" the newly added category before was not added even though it was added on the database. Both Grid and the Treeview shares the same SQL statements on retrieving data.
I've tried adding an update panel and even manually updating the Treeview and still the newly item added was not shown. Possible solution I ever found was refreshing the page and I don't want to do that since its kinda ugly. Take note that upon adding a new category and submit it, it will return to the 1st page and upon adding a new category and choosing the sub category radio button showing up the treeview, the newly added category was not shown.
I need to display the innertext of the each node as items in my menu along with count (i.e; NewObject1(1), NewObject2(2)). I m using treeview but not able to bind this to treeview using xmldom

I have read many posts in the past about TreeView in Custom CompositeControls and using RenderControl but have yet to see a solution. I declare a new Tree in the CreateChildControls method and in the render I try to call the RenderControls method and it gave me an object reference not set to instance of an object error. I have set the SkipLinkText to Nothing, String.Empty and "". Once I do that I get the second stack trace. The control worked when it was a control on the aspx page.
