Web Forms :: Unable To Access Next And Previous Siblings Of A Sitemapnode?
Nov 11, 2010
I have an application where I am binding sitemap to a repeater control for showing horizontal tabs and this shows up fine. Now I have to append some dynamic query string parameters (say id and year) to all the sitemap nodes of the sitemap so that when I bind it to a repeater all the tabs will have these query string parameters.here is my sample code
[Code]....
this is my extendedsitemap within app_code class
[Code]....
And when the sitemap is bound to my repeater control the tabs have url like
[Code]....
Now when I try to click on next or previous buttons on any page to navigate, I am not able to access the nextsibling or previoussibling node.....both of them are null. can any one let me know what am I doing wrong here?
If I am going to access another page from previous page using response.redirect or server.transfer, What can I do so that the previous web page control can be accessed by the another page? Is it possible??
I've used PreviousPage Property to access the controls of the previous page but how can I access objects and instances of classes I initiated in the previous page!
How do I refer to row index. I need to compare the data in the row before the active row in a foreach loop.
foreach (DataRow row in dtGCats.Rows) { tempCG_ID = Convert.ToInt16(row["CG_ID"]); prevCG_ID = Convert.ToInt16( need row -1, row before above current row)
I have a page and clicked on the button there it will open a new page containing some text boxes, user fill all the text boxes and clicked the button now first page open again and the question is : How can I get the vales of text boxes on the current page using both server-side and client-side
There is a restrictions to use of :
- Cross-paging - Cookies - Sessions - Query strings
Is there a method for detecting browser history in C# or do you have to use javascript?I am basically storing IPAddresses, BrowserTypes, Dates, and Where the User Came From Just Before Visiting My Site.I have programmed the rest, but I need to access the browser hisory to get the previous page or site. This will help a little with advertising efficiency.
I made a project to use the access membership provider from [URL] and it works. But I need to edit my database but when I configure my database, I cannot see the tabel, I can only see the queries in mdb file. when I select the field from query, I am unable to update it. My code is as follows:
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

i created a web.sitemap file where I have listed the following:
[Code]....
I need to set some values before the menu item navigates to the page. I'd like to use the same aspx page for more than one menu item and I'd like to avoid the use of querystrings in my code. However, I realize that it's not possible to set the same url in the web.sitemap file. If I don't specify a url, the menu item created is not click-able.
Does a sitemapnode need to point to a page of the current site? I'm trying to add a node that would take a user to a page on another site, for example:
This node does not show-up in my tree view of links, but all the other nodes show. This is the only node that has a url that points to a page outside the current site.
I currently have a working menu driven by a sitemap.I would like to change one of the sitemapnode when a user hits one of my pages. How do i achieve this? I just need to change of the url for one of the nodes in the sitemap.
I need to add a sitemapnode to my screen when the user opens it without adding an actual sitemapnode to the sitemap file. This node needs to include url, title, and description. Does anyone have code to show how to do this in C#?
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
I was given some code a while ago which hid certain nodes from the TreeView but allowed them to appear in the breadcrumb.
Here it is:
[Code]....
I later needed do the same thing but, by now, was using C# instead of VB.
I've tried to translate the VB into C# but the code doesn't work. It doesn't report any design time or run time errors; it just doesn't work (the nodes ARE visible in the TreeView.
I am developing an ASP.NET web page with C#. I have a sitemap document but I want to hide certain nodes based on the user's credentials. However, I am having problems with my code removing the actual node. Visual Studio runs the program with no errors. However, the node is still there. Below is the code I have developed for this. The node changes text to "it worked" as I hope written. However, it will not remove itself. I can get the item to be disabled, change enablement, but I need to hide it completely from the viewers view - not the document.
When I run it. It displays Home>Basic Reporting... (All is under Home tab)
[Code]....
I want to add another root (like Home tab) So the user can select another tab withough going through the Home tab,When I add this code (above code ie.2): It doesnt work, compilation error:How do I make it work.
I am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
I have a site map on my project and I have section which get values from sql database and it changes according to querystring Id value. In my sitemap the title of the page is everytime same. but I want tpo change it at runtime. I am using multiple sitemaps and My sitemap is not the default one. its name is rootSitemap. I tried some code which I got from msdn but it seems doesn't work for me;
[Code]....
Here is my sitemappath code which is situated in my master page;
I am using Session state in my ASP.NET application. The development is done using InProc session state as the option, but now the application is deployed on a Web Farm(Cluster) environment. As a result, InProc session state is not working.
I have changed the session state mode to SQL server so the session state will work in Web Farm environment. But now i am getting a different error because of some of the objects which i have already used with Session.
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I understand that every object that is stored in Session needs to be serialized. But there are some objects which are not serializble in DOTNET.
Unfortunately i am using one of them, SiteMapNode. I am storing this object in session to re-create the breadcrumb based on the navigation the user has performed. I have to do this because there are mulitiple paths leading to single page in my application.
I have tried to do serialization of this object using XML serializer object, but its throwing an exception:
"System.Web.SiteMapNode cannot be serialized because it does not have a parameterless constructor."
I can't change the code of storing the SiteMapNode in session as it is very complex and written by someone else. I have to store this object in session or some other state form so that i can continue using the same code.
