Work on Asp.net VS08. In my master page i need to fill a treeview form database.I done it,i set the NavigationUrl value. When user click a leaf, then they see there wanted page. But then the MasterPage tree become expanded on root. I want the tree will not expanded and tree will the same as before click on leaf.
View 1 RepliesI having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0.
I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue.
I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked.
I have a TreeView menu populated from a SiteMapDataSource. The TreeView defaults to all nodes expanded, but the normal client side expand/collapse behaviour for the nodes is not working. I get one Javascript error in my Firebug console, being:
TreeView_ToggleNode is not defined
What could be causing this?
I am using a treeview control to show the DB values dynamically below is my code
[Code]....
My problem is whenever i debug the code im getting treeview in expanded mode,but i want to achieve like whenever i click on the top node it has to show below nodes
i have a databound treeview in asp.net. how can i expand the root node and have the rest of the tree nodes all colapsed?
View 1 Repliesam using asp .net 3.5 web forms with VB.I have a masterpage that is populating a treeview from a sql db. When a user clicks on the name in the tree it passes the employee identifier (employee number) to a label on the master page i have hidden. FROM the CONTENT page i am reading the label on the master page and updating the label on the content page to match the label on the master page so i can use the emp number to display info. At least that what i want. However, the content page is not posting back when the label updates of course and its one clikc behind becuase there is no post back. Is there a way to make the page postback when a label changes or a textbox for that matter.Here is how i am updating the label control On the mastepage :
Public Property EmpCode() As [String]
Get
Return Label360.Text
[code]...
I have dynamically built my treeview by reading hierarchical data from database, I have divided my MasterPage like so:
<table width="100%">
<tr>
<td style="width:20%">
<asp:TreeView ID="root" Visible="true" runat="server" RootNodeStyle-ForeColor="BlueViolet">
</asp:TreeView>
</td>
<td>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"></asp:ContentPlaceHolder>
</td>
</tr>
</table>
When I click on one of my treenode, I need to set the node.target to the "ContentPlaceHolder1", ie, keep the tree menu as still and let the content page displayed at the right part of the page. However, the node doesn't seem to recognize the ContentPlaceHolder1.
2. I have tried using <frameset> with 2<frame> pages, this way, the node.target can recognize the frame id, code as below:
<frameset cols="25%, *">
<frame src="menu.aspx" name="Menu"></frame>
<frame src="Main.aspx" name="Content"></frame>
</frameset>
But, I need to check user's login permission, I did it with session("userId") variable and I ran into a problem that the session will only exists on the left frame(menu.aspx), not the content page(Main.aspx). I have tried both methods, but one way or the other, there is some function that I cannot accomplish.
In a project I'm working on, the master page codebehind does a load of complex checks and confirmations that decide the navigation list displayed on the TreeView of the page. Now, I need a way to access this list from another front-end page, such as "frontpage.aspx".
This serves two purposes. One, the masterpage will hide pages on the navigation list the user shouldn't have access to, but the user can still enter the page by typing the page name into the URL manually. By being able to browse through the TreeView, I can isolate the whole authorization into a single method by simply checking if the page name exists within the currently used TreeView.
Two, this will allow me to easily change the displayed content of any page without checking the database or storing sessions for whatever specific rights the current user has, as I can just look if the TreeView contains "Products Admin" for example, and then use that to hide or display the section of the page that has to do with "Product Admin" functionality.
I have an asp:TreeView in my MasterPage, which is loaded on demand from a database using some custom functions to fill the Tree. My tree will only ever be 4 levels deep (root -> 1st sublevel -> 2nd sublevel -> leaf nodes) What I want to achieve is preserving the expand/collapse state of this TreeView while navigating between different aspx pages, that all share the MasterPage holding my TreeView. I have been using the methods described in these resources:
[URL]
but I am still not getting the results I want... My TreeView markup in the MasterPage looks like this:
[Code]....
I am using a custom class to save and retrieve the state of the TreeView, the code is pasted below:
[Code]....
In my Page_Load on MasterPage I have:
[Code]....
where Reload() makes sure I'm loading the TreeView for the correct argument (based on a user selection)
And in TreeView_Unload I have:
[Code]....
With all this in place, my TreeView is behaving almost as I want it.. I can expand the root node, it will be populated and I can browse to a new content page and have the same treeview appear in the MasterPage (with same expanded root)... BUT if I try to expand any of the 1st sublevel nodes, I end up with a completely collapsed treeview instead. After some debugging I have come to the conclusion that the "NodeExpanded" event gets the ROOT NODE as event argument instead of the 1st sublevel node that I clicked. When the user changes the option that makes the TreeView re-populate with new data, I simply do a "HttpContext.Current.Session("TreeViewState") = Nothing" to reset my saved state.
If you need more info / code snippets, let me know and I will post it.. But I felt there was no reason to post my complete source, as I have multiple files with about 500 lines of code each (there's a lot happening on the MasterPage, other than the TreeView)
I have an ImageControl inside an UpdatePanel. The image changes upon a Treeview located outside of theUpdatePanel. Im using the treeview _SelectedNodeChanged in the UpdatePanel Trigger. When I run the Web Application I get an Error theMasterPage could not find the Treeview for the Trigger.
[Code]....
I have an app that uses masterpages. On the masterPages I have a TreeView. I would like to only refresh the ContentPlaceHolder & not the Entire masterPage when a link is clicked on the treeView.
I have placed the contentplaceholder in an Updatepanel. I would like to if possible avoid including the menu in the update panel.

I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain
content if a session variable is not null.
I have 2 masterpages. (Default.master and User.master).I have a hidden field in Default.master then how can i get the hidden field value of Default.master file from User.master.is there any way to access that hidden field like: Request.form("hidID") ?
View 2 RepliesI've run into a problem with expanding a dropdownlist when the client is IE6...The screen allows users to optionally specify search selection criteria from dropdown listboxes. Since there may be a large amount of selection data, the usage of which is optional, the selection dropdown lists are only populated on demand (i.e., when the user clicks on the listbox -- I use the OnMousedown event). This improves the overall performance of the system since most users will not use the optional search data, saving time since that data is not retrieved from the Web Services calls and not added to the lists.
After loading the list, I fire the OnClick event to simulate the user's mouse click and display the list items that were just added. For IE7 or IE8, firing the onclick event works perfectly to expand the list. However, this does not work for IE6 -- it requires a second and third click on the listbox to display the list. Note: replacing the fireEvent("onclick") call with alert() works with IE6 (haven't tried it with IE7) -- after clicking on the dialog, the list is displayed correctly. That's not a realistic option for production, but may shed some light on a possible solution.

I need to create a dynamically expanding div tag, and I am not too sure how to go about it. Basically, I have a bulleted list control, which will be inserted inside a div tag. The div tag's height is set to about 70px. When more than 5 list items are added to the bulleted list control, I want the div tag's height to expand to show the rest of the items. What I was thinking is when there are more than 5 list items, to have a little linkbutton with the word more, and to click on this button, which will then expand on the div tag.
View 5 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.

View 1 Repliesi've made an Ajax accordion in a page. the problem is that the accordion is not collapsing or expandingthis is the code:
[Code]....
I'm trying to accomplish something like this [URL] , where you have images displayed in several columns, but as you resize your browser, columns will (dis)appear so to fit what you can see on the screen.
PS: Bear in mind that I'm quite a ASP.Net noob
Ok so the story is my users need a multi-select dropdownlist, which doesn't exist in ASP.NET, so the simple solution I'm going with is I'm using listboxes with multiselect on and I start them off at size 1, and onmouseover I change the size to say 10, onmouseout sets it back to one. Simple enough and the users don't know the difference.
Now, my issue comes from the fact that since I have any number of controls on my web app, I've set these listboxes to higher z-index numbers than the other controls, which creates a problem: on my listboxes closer to the bottom of the page the list expands below and not above, and part of the listbox goes under the bottom of the page but since onmouseout resets the size of the listbox I can't scroll the page down.
Does anybody know what I need to set to make it expand up instead of down?
edit Also, some may ask "why don't you just rearrange the listbox to a higher position in the page," the reason this isn't a viable option is I have well over 40 controls on the page and it they're grouped cohesively, I didn't just randomly place them where they are.(ie. investment info in one section, account in another, suitability in another)
I'm having a problem with <%= obj.ClientID %> expansion, in a .ascx user control.
I have a .js file, containing a javascript function:
function doSomething(objectId)
{
...
}
I have a .ascx file, with some html elements, and in one element's onclick= I want to call doSomething(), passing the ID of an element in that .ascx file, where the passed ID is of an element other than the one being clicked on, so I can't use "this.".
Maybe it'd be clearer with an example.
This works:
<script type="text/javascript">
function redirect()
{
doSomething('<%= top.ClientID %>');
}
</script>
<div id="top" runat="server">
<img src="..." alt="..." onclick="redirect();"/>
</div>
But this does not:
<div id="top" runat="server">
<img src="..." alt="..." onclick="doSomething('<%= top.ClientID %>');"/>
</div>
When I look at the source, I see that the <%=%> substitution has not happened, instead of "doSomething('ctl00_myControl_top');" I get "doSomething('<%=top.ClientID %>');"
For some reason, the script expansion happens in the former case, but not in the latter. The work-around, of course, is not acceptable because it will break if I include multiple copies of the control on a page - only one instance's "redirect()" function will be accessible.

View 5 RepliesI 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.

View 1 RepliesI have ContentView which has 'Table of Contents' and another view (DescriptionView) which has the total description of these contents. Each content description in DescriptionView is in different sections and I have implemented accordion to manage this.
[Code]....
When I click on each content in ContentView I navigate to that particular section in the DescriptionView by the of the anchor tag which i specify in the url. My issue is I am not able to open that section which will be hided using accordion. Hope am successful in explaining my query.
