C# - Accessing Server Control From Other Webform?
Dec 29, 2010
I have 2 webforms with 1 ListBox Control on each of them.
How do I access the Listbox that's located on webformA from webformB?
For example I wish to declare something like this string name = ListBoxWebformA.SelectedValue.ToString(); on WebFormB, so that I can work with that value in the code of WebFormB.
The ListBox on WebFormA lists several names. When I select a name from the listbox and press the OK button I call Response.Redirect("~/WebFormB.aspx");
So from WebFormB I wish to access this "name" by putting the selected value into a string.

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....

I have a piece of code that is just HTML. It was previously created as a user control. Within the application i'm working with there are two seperate websites that are interlinked to make one website. There is a documents section where users do not need to login and a data section where users need to login. The design was implemented long before I was hired. My problem is I want to use the code from the documents website with the data website but I can't seem to register the control. I only one this piece of code in one place so when it is updated it doesn't have to be in multiple places. I tried setting "src=http://website/doc/doc.ascx" but this errors out saying
<%@ Register Src="http://website/doc/doc.ascx" TagName="docs" TagPrefix="temp" %>
Parser Error Message: The file '/documents/http://website/doc/doc.ascx' does not exist.
It adds the directory as part of the src. How can I have it point to this location http://website/doc/doc.ascx ?

I'm developing an ASP.NET user control in VS2008 that writes to a SQL Server 2005 database. I've published the control to a SharePoint 2007 MOSS page using the SmartPart addon. The control consists of a few text fields and a submit button that writes the contents of the text fields to the database. When I test the control in the Visual Studio debugger, it works fine. When I try to submit data from the SharePoint page, I get the error shown at the end of this post. Last time I saw this, it was a database permissions error, but I've granted my site's default application pool read/write access to my database. Does anyone have any idea what else the problem might be? Also, how can I double-check the credentials that the SharePoint page is using to access the database, since I still suspect that this is a permissions issue?

If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

how to set webform control proprieties in asp.net and ajax control using javascript. I have asp page that has checkBox, TextBox, MaskedEditExtender, and RegularExpressionValidator.
I set the mask for MaskedEditExtender as Mask="(999)999-9999" and I set the ValidationExpression for RegularExpressionValidator as ValidationExpression="d{10}".
I want to change these two properties when user checked the international checkbox to: Mask="999999999999" and as ValidationExpression="d{12}" Using JavaScript without interrupting with server side and when the user unchecked they get previous value so the interaction should be only in the client side.

I'm beginner at C#, asp.net and I took a course about databases (fundamentals of Databases) I wouldn't ask such question because:
The thing I am required to do is an e-commerce project (small one) and I am stuck after connecting the database from SQL Server to Visual Studio using server explorer?
How in a simple manner can I send SQL queries and retrieve data and display it?
The problem is I have asked this while they know we didn't take web programming courses and I have to deliver the project next week (e-shopping cart + registration + signing in) !!!!

I have a ReportViewer (ver 10) that is rendering far wider than the box it's meant to display in. The problem is that the Parameters area is appearing much wider than the actual report area. If I put an "overflow: auto" in the div that contains the ReportViewer control, then I get a horizontal scrollbar at the bottom, but then in order to click the "View Report" button I have to scroll way over, thus moving the entire report.
Ideally I would like the Parameters area to stay stationary, but a horizontal scrollbar to appear on the report area so that it can be scrolled if necessary. What is the best way to go about doing this?
Here's what my control setup looks like now:
<div class="reportingFrame" style="text-align: center; width: 100%; overflow: auto">
<sam:ReportViewer ID="UiReportViewer" runat="server"
AsyncRendering="False"
ProcessingMode="Remote"
ShowExportControls="False"
ShowPrintButton="False"
ShowPromptAreaButton="False"
ShowRefreshButton="False"
SizeToReportContent="True"
Width="100%" />
</div>
Currently I'm looking at some jQuery tricks to reformat the output from the ReportViewer control into a better system

I have a Webform with a large number of user controls on it, they were auto generated as part of a formview.
I would like a way (Add in etc) to print a list of all of the names of the controls for me to use for the code, rather than having to go through and write them all down.
does anyone know of an add in or an easy way to do this in VS2010..?

I set a reference to AjaxControlToolkit.dll and this added all of the toolkit's controls to my toolbar. I then tried to drag and drop one of the controls to my webform and nothing happened-no error message, no control added to the form. Double clicking the control also did nothing. The web site compiles with no errors, I also tried to bounce VS2008. I am running Developers Edition on Windows Server 2008.I was able to add a Script Manager control

If I develop a Windows User Control and host it inside an aspx web form, does the user's machine accessing the aspx page needs .NET Framework?
Does the Windows User Control hosted inside an aspx or web form requires any downloading of the control similar to an ActiveX control? Or Is it rendered like a HTML page?

Currently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.

I migrating a large asp.net webform site to MVC. I want to mix match old asp.net web form and asp.net mvc together for sometime and gradually convert the webform model to pure mvc model.
So i copied all aspx/ascx files from the old webform site to my mvc project. Now when i compile, i get build error. Code behind files can not find any server controls inside their aspx pages.
I can solve this problem by adding a desinger.cs file for each of the aspx,ascx file but that simply is not viable for me since i am dealing with hundreds of aspx pages and user controls and i can not afford to manually add a designer file for each of them.
