i want to be able to load user controls and populate them with data from a sql database at runtime based on a status field in my database but im struggling to do this.
my default page.aspx holds the user controls (acts like a container). at the moment i had referenced all the user controls to load up when the page was loaded so:
[Code]....
[Code]....
i then created a procedure which reads from the database the "status field". so if the status field is "pending" then i want the uc:GRLOLApproval control to show up but im not sure where to put this code or how to do it. i want to be abel to load the control at runtime and run this code. in my default.aspx.cs code i have done the following in the page load:
[Code]....
i tried to reference te user control in my default.aspx page by doing: protected GRLOLApproval GRLOLApp; but it wouldnt recognise it because it not been reference in the source file.how do i reference it so that i can read the data from my database and write to the fields in uc:Collectionrequest. (I have exposed the properties in the uc:CollectionRequest that i want to access btw) have been working on this for days now and just cant seem to load the user control or access any properties.

I have this GridView that have it's DataSource as a list of previously selected products. For every item on it, I need to Eval it's ID and load a specifc form that the user must fill, then after that i've got to update the GridView.

I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.
What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.
As a result I am loading all the user controls on each postback.

Do you think it is wise to load the background-body image dynamically in a CMS application from SQL Server 2005? Granted I would have to generate a sql statement based on size of the page to show the correct image. Anyone run into any pitfalls?
Can any one let me know "How to load the dynamcially added HTML Controls(Controls added using javascript) during the postbacks without loosing their values?
I have a problem that I can't solve when I load controls dynamically. I have 3 states on a page that I traverse through and I load as many buttons on the page as the page state number + 1. For example, on state 0, I load 1 button, state 2 - 2 buttons, etc. The problem is after I move to a new page state, the button click event(s) of the dynamic buttons will not be wired up and won't fire until the second click of each button.
I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?

how to create user control dynamically in a web form ?When i am creating server controls of user controls are not instantiated and it is not getting initialized .when i am tyying to initialize its properties error occurs tha object instance not created .
I am new to ASP.NET And I am have THE hardest time understanding how to work with forms in ASP.NET. Here's what I am doing:
Dynamically add User Controls to a PlaceHolder based on some int value (which currently is passed in a HiddenField).Fire an event if the WebControls inside of the User Control change, then handle that event in the Main Page (i.e. save the input to DB)When the user clicks the "Next/Continue" button, the next controls for the next page are loaded. And I guess maybe I just can't seem to get how things work in ASP.NET, because I am really struggling with the general idea of how ASP.NET flows.
Should I be dynamically loading the controls in Page_Init, or Page_Load? Or should I load the controls when the buttonclick event is fired?Do I have to add the axCtrl.OnDataChange += new EventHandler(HandleAxControlDataChange); line on Page_Load? Or should I put this in When I first load the UserControl, I need to initialize some WebControls within the UserContorl. Is there a way to know if I have loaded new user controls into my placeholder? I can't use Page.IsPostback, because after the first page, every page is a postback from the buttonclick.
I have a page with textboxes and a button. I would like to dynamically load the textboxes with data that is in a detailsview on a page load or detailsview load. For example, ID, first name, last name. I find out how to do this on another page with a selected_indexchanged event with a gridview. See the code below. I'd like to be able to do the same thing but with a detailsview in the detailsview_load event.
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged txtPK.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(1).Text
txtFirstName.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(2).Text txtLastName.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(3).Text End Sub
It seems when I try to dynamically create multiple instances of a User Control, I get an Object Reference Not Set To An Instance Of An Object error on any ASP control that I'm using in that User Control
Here's the class where I'm creating them.
[Code]....
Am I able to successfully refer to a panel on the page that I'm calling this routine from simply by ByVal ... As Panel, or should I use HttpContext?
