just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.net
we usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds
dataGrid.DataBind()
What if if I want to edit or evaluate the data inside the DataSet?
How can I manually populate a listview control without sql connection?
View 3 RepliesI'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).

how to populate datagrid based on dropdownlist changing
I'm tring to populate a datagrid using a stored procedure that returns about 20 fields (this part I figured out), but the kicker here is that for this one particular page I only want to display about 6 of those 20 returned fields.
I did find on passing the procedure the parameters that are required, and populating the datagrid, but haven't found anything (not that I can tell) that explains how to only view certain fields that have been returned.
I'm using VS 2008 and VB for my coding against a MS SQL 2008 server. All of the stored procedures are working with current windows applications.
So I have a dropdownlist and I'm trying to populate it with values in the database. For some reason, half of the rows has no value. It's happenning in a sequence as well, like the first row has no value, then the second row has value, then the third hasno value....
Does any one know why it does this?
This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:

I'm trying to populate a datasource for a dropdownlist (which is actually in an insertitem template field within a detailsview on the same page) with a selectedvalue from a gridview. When I select a row in my Gridview 1, I get the "no value for a required parameter" message. ( and I have tried various alternatives... setting the selectedvalue of the grid to a variable... setting the selected value of the grid to a textbox nothing seems to work. It seems like this should be a pretty simple thing. I think I'm missing something obvious! Here is my code:

I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo

<asp:TemplateField ShowHeader="False">

<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

I have a website on the IIS but it has only the aspx file. Now I need to add the code behind for some pages. How do I go about this?
I've been trying to add the attribute "codebehind" and "autoeventwireup" on the top of the aspx file but no luck (the page_load event is not being called). Also, if I double click on the button from the design view in Visual Studio, it creates the javascript handle (not the server code).
Is there a step by step guide on how to enable .NET 4 on IIS 6 running under Windows Server 2003 64bit?

Using the Entity Framework that I generated. I have a Roles table created during the default system AspNetSqlRoleProvider security set-up.In the Roles table, I have an ApplicationId uniqueidentifier column. Which has a guid populated in it, which doesn't change for my application. I need to add a Role manually through my app using the entity framework. However, when creating my Roles object and setting Roles.ApplicationId. It expects a type of Guid. I have the ApplicationId in my web.config app settings. As it shouldn't change. But it is returned at string. I cannot type cast the value either to use in Roles.ApplicationId. What can I do to use my current ApplicationId value when trying to create a new role manually using the EF?

View 3 RepliesI have a Problem with an very old ASP.NET 1.1 application. I cannot open (load) it in Visual Studio 2003 (on a Win 2003 server) any more. I get an error message,that the component for the communication with the "Front Page - Server Extensions" cannot be found (I use a german VS 2003, so I have not the exact English message). The extensions are installed. That can be the reason for that respectively how can I solve this problem.
Another Question: Is there a possibility to open an ASP.NET 1.1 application in VS 2010? Tthe upgrade wizard tries to convert it, but the conversion results in errors.
