Web Forms :: How To Custom XML Data Source For Navigation
Jun 2, 2010
I'm designing a website that should have horizontal menus (main menu, and sub menus) underneath each other like:
Home | **Categories** | Contact Us VBScript | VB.NET | ASP.NET
(** indicates the selected main menu item) Where VBScript, VB.NET, and ASP.NET are menu items in the Categories main menu item.
Initially, I tried using a separate sitemap file, but came across an error that forced me to write a custom xml document for the sub menu (code below)
[Code]....
I've created an asp:Menu control to use for the sub menu (it's blank until a main menu item that has child items is selected), and I'm databinding it on MainMenuItemClick (code below)
[Code]....
MainMenu has it's items hard coded into the html, but I'm going to move that over a sitemap later, what I'm struggling with, is how do I get the SubMenu items to navigate to the URLs I'm specifying?
I am binding gridivew with custom datasource. I have 3 columns and I want two columns to be editable. right now grid showing the data but i want it to delete and update as well.
web-based so it can be used by users and hopefully using the class SQLSiteMapProvider which allows for saving sitemap in a SQL Database instead of XML.
Basically I want to take the following:And make it match the styling of the rest of the application.I am creating a custom error page in my C# based project and I want it to be able to show the same information that is displayed in the ASP.NET default error page. From fiddling with reflector I can see that this is generated through HttpException.GetHtmlErrorMessage() but when I try to use this in my exception it returns null.
I'm using a custom sqlsitemapprovider to get my site hierarchy out of the database and display my navigation. Now, I have the following main (parent) nodes:
Home - Products - News. What I want to achieve is this, suppose you click on products then a subnavigation appears like this:
productGroup1,productGroup2, productGroup3.
But when you click products, no selection was made from the subnavigation, how would I achieve that if someone clicks on products, the first product with content from the first productGroup1 shows up?
To visualize this: I click on Products -> Subnavigaton gets rendered -> PG1 - PG2 - PG3 -> page displays product1 of PG1
Is there as build in manner to accomplish this or how would one create a method to make this work?
P.S.:For my navigation, I'm not using any build in navigation controls, I'm rendering my menu as an html unordered list e.g: <ul><li></li></ul>
However, if I have the source code, shouldn't I be able to debug it to step through and see what's going on? The debugger stops on the page that is consuming the control but I thought as long as I have the source it would stop at breakpoints in the custom control as well.
I am Trying to hide Navigation Menu Item on my master page based on a selected item from a Drop Down List on another page. I think i need to use a session to get the pages to communicate, which i can do just fine. Im having a problem putting together the code to actually Hide the link based on the specific answer of the DDL.
My issue is, i need to display my Table(A) categoryname in my vertical menu such as
ashok kumar suresh john.
if i click ashok, with respect to its id,(say id is (1),it should pick the subcategoryname (2nd table's) name corresponding id(1) from 2nd table...and it should display as sub menu is it possible.
i have asp.net treeview control on my masterpage which is associated with many pages now my requirement is that when ever iam clicking child nodes in the treeview its getting navigate to the appropriate page but treeview not retaining its position.its getting collapse to its default position.
I am using a SiteMap data source boudn to a navigation control. I would like to also put this in the footer (sort of like the bottom of Yahoo! pages) where all items are expanded and static.
So my major heading would be across the top (horizontal) and the sub items would be indented vertically below and always expanded. Is there a way to do this? Check out the bottom of the BlackBerry DEVCON 2010 site for an example:[URL]
I am trying to workaround a case where I have to design my page similar like msdn library page whew left nevigation is collepseble as well as dumemic extemded as per tje wodtj of tree item in tree .
I have some user controls registered in the web.config.
Now I need to load some of them dynamiclly with the page.loadcontrol() function. This function needs a virtual path to the .ascx file. Is it possible to get this virtual path (that is the same as the source path in the config) by the tagname?
I don't know it happen just to me or Others have the same situation too . All the time when i bind a DataControl to an ObjectDataSource in "Configure Data Source" wizard of ObjectDataSource,when i set parameter source as "Control" in "ControlId" DropdownList there are TWO Item of every control in the WebForm , while it make sense be one.
This is my code and i am only able to edit the one data under the category school.But what i nd is to edit the other categories like the name,email...etc..how do i modify my code in the update command.Another thing is to delete the data how do i do that?
I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?
I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?
I have a GridView or DetailsView and its bound to a CslaDataSource.I noticed that the "Object_Select()" event is fired automatically with every time the page is loaded or refreshed.How I can perfrom mnaual biding between the DetailsView Control and CslaDataSource ?I want to control binding via code using the DetailsView.DataBind() method in certain cases only.
I'm creating a page that allows the user to create a new object that will later be stored in the database. The problem is that the design of ASP.NET data controls seems to insist upon only working with pre-existing data that has been stored in a database (or XML, etc...).
I'm basically trying to get the user to compose a list of items and specify a quantity for each item. I could do this by generating table rows but the rows are lost at each postback. The data view controls seem to be designed only to be bound to a data source but until the list is complete, the data can only be in memory.
What control is appropriate for this and how can I achieve this with that control?
