I'm finding a dropdown in an ascxcontrol on my aspx in the following way.
Dim cp As ContentPlaceHolder = DirectCast(Page.Form.FindControl("ContentPlaceHolder1"), ContentPlaceHolder)
Dim ascx As UserControl = DirectCast(cp.FindControl("drpType"), UserControl)
Dim drpType As DropDownList = DirectCast(ascx.FindControl("drpType"), DropDownList)
Is there a faster way without having to acces all the elements on the page?

I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs)
'set selected user from gridview.

This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?

View 4 RepliesI'm writing a Repeater Control in an ascx file which renders some info as a row that comes from a complex search. In an aspx file I have the query to retrieve a DataView that gives me the XML string with the info needed to feed the Repeater. The problem is that I don't know how can I pass the XML string (or the DataView or DataSet) from the aspx to the ascx file so as I can render the info.

I have a user control that I'm adding to a webpage dynamically. The ascx has a couple of controls that I want to have access to at runtime. I can access the ascx itself, but none of the controls on the ascx are available. I have tried adding a simple public variable and also tried adding a public property to the ascx, but I am unable to get access to either of them at design time (compile errors). I added the following to the code-behind of the ascx control:
Public Property areaCode() As String

I have an ASP.NET page (WebForm) on which I set the content of a central DIV by dynamically loading one of five user controls during Page_Load, dependant on the stage of the application.
One of the user controls contains radio buttons and a text box together with a submit button. What I want to do is process that information when the form is posted using the submit button.
I could do this with an AJAX call using jQuery, but I don't really want to do that, so I'm trying to access the form data on postback, but on page load following the postback the data is not present in the Request.Form object.
Looking at what I need to do it seems pretty simple and I'm sure is once you've got your head around it, but I can't find out how to carry this out. Some of the things I have read refer to event bubbling, but that doesn't make too much sense in this scenario.
EDIT: To clarify, I want to post the page back to itself to capture the values from the form elements via the Request object, store them in the database, and then display a confirmation message (or something else) on postback, and not re-display the same control again. So I won't be loading the same user control again.
I need to get a value from an API I made with ASHX and normally it is called from javascript but I need to call it right in ASP.NET I figured this shouldn't be a problem but I'm not sure the syntax.

I'm making a game for a school project We've created a character that moves around the screen and creates blocks behind him as he moves around.We want to make it so that when the character moves from one edge of the screen to another, it fills the screen. So in order to do this we have a Points array that stores every point the character touches on his way to a wall.We then fill the Points array with "formsurface.fillPolygon(Points)"Now I'm wondering is there anyway we can retrieve all the points that are WITHIN or INSIDE the Points array we made? ( remember the points array simply contains the outline or the path the character created, we're filling inside that outline)
View 1 RepliesI have tried this but it does not work:
[Code]...
What is the solution?
I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4
Allen Iverson,28,7,4
Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
textboxoutput.text = PlayerName & " averaged " & PlayerPoints & " points, " & PlayerAssist &" assist, and " PlayerRebounds " &" rebounds"
So basically, I want it to where the user can enter a basketball players name and display the values for that name.
I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

I am trying to implement a Web User Control into one of my APSX pages but keep getting the following warning:
Element 'IntFilter' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
The user control is defined in the same web project as the aspx page.
Question: How do I resolve this warning (I do not want to move the control to a separate project)? Also, what do I need to do to enable IntelliSense for this control so I can set its FilterTypeSelection property from ASPX?
Code for "~/FilterControls/IntFilter.ascx"
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="IntFilter.ascx.vb" Inherits="StaffSupport.Filters.IntegerFilter" %>
[Code]....
Also of note, if you drag the control from the Solution Explorer to the page in Design view it will add the references you need (though it was still generating the warning for me). If you drag it to the page in source view it will add an a tag with a href to the element.

How to get the value of Default.aspx textbox1 control into webusercontrol Textbox ?
View 1 RepliesIf Page1.aspx opens Page2.aspx in a window, how can I have Page1.aspx refresh once Page2.aspx is closed?I have a page with data on it and I have a LinkButton set up so the user can edit that data. The LinkButton launches another windowed page with some text fields and a "Save" & "Cancel" button. Once one of those clicks I execute a save and close the window OR just disregard the information and close the window. I was hoping to have the initial window with the data on it refresh once the 2nd window is closed.
