Web Forms :: ASP.NET Menu Custom Control Populated Using LINQ To SQL?
Jun 16, 2010
how to programmatically create an ASP.NET Menu Control populated using LINQ to SQL (with an unknown number of levels) and couldn't find one anywhere. It took me a while to figure out the logistics of it so I thought I would post my final solution so that you don't have to spend time figuring this out for yourself. Note that I am a self taught developer so I am potentially breaking any number standards coding protocols.
In this example I am working with an ASP.NET project named Virtual. Non-Standard NameSpaces are Virtual.(tools, components) etc...
1. Create your database table that will eventually be used to populate your menu control.
I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details
I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.
I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoint hits Page_Load function (before If (!Ispostback)) , listBox.SelectedIndex is becoming -1.
One more thing here is, I am placing this user control in an SharePoint application page to be specific checkin.aspx page . ( I know this should not be done, but that is the requirement for me)
When I implement Custom web control inheriting ASP.NET Menu Ajax is not working. I try to Override Render method and generate Li's rather than table.I try to use Control Adapters, but when I am not using adapters for some pages ithe base adapter is generating just hyperlinks with span. I do not want this way. So I can not use these.
i have created menus using menucontrol (populated using database) its showing me menu items properly.now menu items goes out of screen (viewing area of the screen)i want to wrap that menu items means if the menu items goes out of the screen it will automatically shows the remaining menu items to the next line... and i have taken menucontrol in span tag..
I need to populate a dropdownlist with results from a linq query done in my controller. I want users to be displayed but when the item is selected and submitted, the userid is passed back to the controller.my controller:
I need a way to define a template that the control should render before each item..I currentky have the following code:
[Code]....
But Im kind of unsure about where to place the following code:
[Code]....
Since I whould like the template defined in the BeforeItemTemplate to always get added before the actual Item/<asp:MenuItem>..so I can add elements before and after each MenuItem..
I am working on a custom menu control, partially as a learning exercise, and I am having trouble with Visual Studio's IntelliSense support for it in markup view.The conventional ASP.NET menu allows you to place an arbitrary depth of <asp:MenuItem/> elements under the <Items>...</Items> element. I'm after the same behaviour for my menu.Mine unfortunately does not. VS insists on an empty tag:
i have this situation: i have to build a menu with datasource from the db, because i have to filter them among the user that is loged in. i have tried building a menu using repeater, and all this works fine till i realized that i wanted the menu with more than two levels. i have also tried with treeview, but i really don't want this solution (problem with the style and the treeview doesn't have a pretty view).
Is 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.
I am trying to style the menu control to allow the menu items to float to the right of the container, however I am unable to do so as whenever I am styling the a, ul or li it keeps getting overidded by asp.net and floats everything left.
What I want is to show menu items Administrator or show user menu items.Show menu items using login...How I can do it with role provider, control menu and siteMap in masterpage?
We have to develop an application which has a Vertical left pane menu control which displays all the web pages (A,B,C say). Now if user is in page A and filled some data and clicks on menu control to go to page B, all the data in page A needs to be saved. Also if all the required field in page A are not filled and user navigated to page B, there will be one ! sign after the menu so that user can understand that there some some more fields need to be filled up.
We are planning to place the menu control in the Mater page. Please give me some direction to do this. My question is:
1. If user change menu (In Master Page), how should we save data?
2. How should we display the ! in the menu control?
I saw first few video tutorials and they seemed to get the values from the control like text = Textbox1.text; All the form fields are got this way. On the other hand in mvc all the request parameters are populated into a model object. I am not sure whether this already exists or not, but is there any mechanism built-in asp.net which would populate the data from the controls automatically and give us a nice model object which can be saved directly onto the db. Something like this:
<asp:textbox ... ... value="${model.name}">
I don't remember the exact syntax of textbox control. So in this case the textbox would be filled when get request and put into model object when posted back.
I know that the code depicted below will not work but I am including it to convey the idea of what I wish to accomplish. I want to use a different SiteMap to construct the menu on the displayed page for each of three different classes of service (COS).
I set a session variable named "COS" at the login and want to test its value prior to rendering each page. I want to display a menu based upon the appropriate COS. Here is my first stab at it but I know that I cannot include <asp:...> controls within the "case" statements. Can anyone suggest methods of doing this? I know C# and can use that but I do not know how to select the proper sitemap within the <menu> control. I am also using a CSS in my production version.
I am using frames in my webpage.in one of the frames i have a menu control whose items are database driven.when click on the menu item, i want another page to be displayed in other frame.
now i want to pass the the selected menu item text to the other page using session variable which is in the menu item click event method.but the thing is when i click on the menu item, the click event is not firing.
is there any better way to pass the selected menu item text to the other page?
I am trying to implement dropline menu using asp.net menu control. I found JQuery dropline code @ Dynamic Drive & currently using CssFriendly Adapters to get neet CSS, but i am unable to implement it as menu control renders its own css names.
I am working with asp.net 2.0 I have 1 problem Regarding Menu Control I used menu control in Master page. Now I have to find out Menu Item from Menu control depending on Condition. how to do that on server and Client side.
I want to learn how to use form view but i can't find any tutorial that have a get data from database and display using form view or inserting data to database.
