I am trying to implement some tree like that in ASP.NET:
However, this is a TreeView component in the Navigation Tab. I want a DataGrid in a tree view which isn't navigation. Is there a ready FREE component out there?? If not, what is the right component to start with to build such a tree component???
I'm not in a hurry, it will be better for me if I can build my own, but I want to know the component to start with?is it the DataGrid?

View 4 RepliesI have a tree view which uses my SQL database and tables to generate the tree view and list of reports under the different categories and folders. That all works perfectly... However, since some of the reports are private, and some of the reportsare pubic I was hoping to be able to adjust the image of the report to a different icon to differentiate between the two. Here is my code which generates the tree view and lists the reports below it:(All code is in VB.NET)

I've thought about this but havn't tried to many options, figured I would see if anything stood out as easy as node.setimageurl = "~/images/image.png" etc.

When I click on the +(expandCollapse) near the node that appear under the CurrentProvider.CurrentNode of the page- just in the first click, in debug ,I see it's cause to commit the OverrideChildControls that I write and then goes to PageLoad...it's disrupt everything..I want that all the Nodes will be load without Load all the page Did someone had this problem?I will be glud to know the solution..
View 2 RepliesI am trying to build a tree view and was able to create one.The tree is a multi-level tree(6 child levels). The problem I am facing is that for some node the node text is more than 260 characters and for those nodes the node is not expanding and showing the child nodes. I read in the web that the Max lenght for the node Text is 260 only. I am picking these node text values from database and they can be longer than the 260 mark.

View 1 RepliesI have a web application where I am using asp.net tree view control to show data. No I want that this tree view structure has to exported to excel. Following is the code which do this for me.
private void ExportSiteStructure()
{
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
TreeVWSite.RenderControl(oHtmlTextWriter);
if (TreeVWGroups.Nodes.Count > 0)
{
TreeVWGroups.RenderControl(oHtmlTextWriter);
}
Response.Write(oStringWriter.ToString());
Response.End();
}
It works perfect but the report what it gives me contains all parent and child node of tree view get palced in excell cell as well as icons and checkboxes which I have use. What I want is to have only Text in excel cell that represent node of tree view and not those icons and checkboxes associated with them.
I am working on a project just like gmail we have, I want tree view left aligned to be set size same as of my right mailbox.
