Forms Data Controls :: PdfViewer - Select Pdf From TreeView?
Oct 25, 2010
Im trying to put together a small document library. I have a treeview (obout.com) that lists all the items in the library. Each can be selected which navigates away from the treeview, opening a pdf. I just added a PdfViewer so that I can view a pdf within a frame on the page.
I would like to be able to select the pdf from the treeview and have it display to the right in the pdfviewer. It would be really nice if the pdf viewer was in some kind of ajax update panel for the update. I pretty new to all this stuff and have a good idea of how I want it to work, but Im not skilled enough on how to implement it.

I have TreeView on a Sharepoint aspx page. The tree is populated dynamically using a Sharepoint list containing a folder-stucture. I would like to handle Select-actions but I am not able to.. the SelectedNodeChanged event only seems to occur when I select the outer-most nodes. Minimal example code for the UserControl where the TreeView is located is found below.

I would like to implement a xhtml website with 2 divs: the first contains some imagebuttons to control the treeview which is placed in the second div below the first one. One task is to enter a search string in the div-panel above and click on a search button. The needed result should be: the matching item in the treeview below marked and scrolled into the view.
I have implemented the Button-Click Event within the C# file code behind.

I have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?

I use asp.net 4 and c#. I have a TreeView and I would like select an existing node programmtically.
SelectNode() method is read only

My Code:
protected void uxTreeView_DataBound(object sender, EventArgs e)
{
TreeView myTreeView = (TreeView)uxManageSlotsDisplayer.FindControl("uxTreeView");
myTreeView.Nodes[2].Selected = true;
}

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 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'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?

My TreeView controls is rendering CheckBoxes on Leaf nodes. I want to bind to those nodes the ID of the underlying data item. I am not sure I can do this declaratively or if I need to hook up to the TreeNodeDataBound event. If the latter, how would I go about achieving this?

I have a treeview control with Checkboxes, when 1 is checked/unchecked I would like to run some code, but for some reason nothing is being raised when I click on the checkbox. If this were a datagrid I'd be looking for the autopostback="true", but this control doesn't appear to have anything like that.

I have a treeview on an ASP site that I populate from a DB using a Stored Proc that delivers XML. I am using an XML datasource that is loaded from the SP programmatically in the dadtasource's onload handler (if there is a way to load it from an SP declaratively, let me know). The treeview has its 'ShowCheckboxes' property set to "Leaf" (see code below) so that any leaf node can be checked.
The problem is this - I have a 'Checked' attribute in the leaf nodes of the XML (see below) that I would like to have databound to the treeview (I have databound the Name and ID attributes successfully) and I can't seem to find a way to do this. I also tried programmatically, but the treenode's dataitem property seems to have the value 'Nothing' even after the tree is databound.
How do I bind the 'Checked' attribute to the treeview's checkboxes? (Prefereably declaratively)
Example of XML here:
[Code]....
Note that nodes have Name and ID attributes, and Leaf nodes have Chacked attribute.
Here is the declaration of my treeview:

Here is the declaration of my XML datasource
