.net - How To Submit Data From Web User Control
Jan 14, 2011
I have a form that I put on the Web User Control, but "Submit" button is on the parent page.
The form contains user information. That same form displays for admins to edit a user and for the user to register and update profile.
I wanted to have the form in only 1 place to display in those 3 places.
The admin page will have a little more information on it, along with the "user info" control.
how can i reference items on the control page from the parent page?

I've created the beginnings of my new web application, but I am often coming up against the issue that ASP.NET renames elements IDs or in the case of form fields, their names.I have a form which is basically a sales system. It is essentially made up of two User Controls, one is a form for Customer Details (name, address etc) and the second is a form for the customer's purchases, it consists of a number lines dynamically created by Javascript created as you list the items the customer is purchasing. Both these sections are User Controls because they are to be used for other areas of the system where this data will need to be recalled/re-entered.When the USer Control is loaded, the field which contains the Customers' Name is renamed "m$mainContent$customerForm$name" I understand where this comes from, "m" is the ID of my Master Page, "mainContent" is the main Content Placeholder and "customerForm" is the name of the User Control.
In fact, in my case, this will always remain the same on all forms, so it is relative easy to overcome... but... suppose it wasn'tI can see there are ways I could deal with this with Javascript, but the form doesn't need an AJAX submit, a normal Post will do fine for this, so when I open up the recieving page I want to call Request.Form("name")% to save the customer's name into the database, but of course I really need Request.Form("m$mainContent$customerForm $name")%How would I dynamically extract those prefixes from the posting form to ensure that if I rename anything or use it in a different scenario, the problem will not break it?I am using .NET 2.0, so can't use Static Client.

Basically, I have created a search facility which is housed inside the navigation control on every page. My predecessor set every single page up enclosed in a form for postbacks.
I need these postbacks to continue working however I need the search when submitted to post to go to a separate page and post the data. I tried various methods such as "postbackURL" on the ImageButton but it didn't do anything.
Below is an example of my form code from my navigation.ascx control:
<fieldset>
<div style="height:8px;"></div>
<asp:TextBox Width="116px" CssClass="search-textbox" Text="Search" style="height:

I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?

I have a view with a few checkboxes that can be selected or unselected. I'd like to always register any change in a checkbox, without the use of a submit button (the user could forget to do it, and it would waste time). So, is there a way to handle this inside the view? Up to now, I've only used the controller to do that job.

What is the best method to do data validation? I want to do data validation when the user exits a control so that he gets immediate feedback. I can use the Validating event or the Leave event for that. The problem is, that if the user doesn't know the right answer, and just wants to click the cancel button and leave the form completely, it won't let him. It continues to give him an error message until he completely deletes his answer. Very frustrating. Does anyone have a good method for doing this?

I have several UserControls in an ASP:Repeater. They are 'Add to basket' User Controls with a text input for quantity and a button to add the item to the basket.
My problem is the value is being reset to 1 whenever I enter a value into the quantity text box. I think this is happening because the containing page reinitialised the repeater (which holds the UserControls) and the quantity is one again before the UserControl's click event is fired.
how to capture the value in the textbox before the Postback occurs, I am happy to stick this data in a session for now.
I am thinking I need something along the lines of PreLoad? But that didn't work for me

I have a created a user control. This user control I dynamically load on a page inside Telerik Panelbar control. I have done all necessary coding to save the viewstate and load this dynamically created usercontrol every time page loads.On this User control I have a asp panel. By default this panel is invisible. When user clicks a button on this user control panel is made visible. On page load of this user control I populate all the controls on this panel.Everything works fine if I dont load this use control dynamically but when I load this user control dynamically and if I make panel visible by default then only all fields on the panel are populated. But if I make by default invisible and on button click make panel visible none of the text boxes or comboboxes are populated. I populate comboboxes on page load of the userControl but inbetween postbacks all the comboboxes on the user control loose data.[code]...

I have a user control inside of a repeater that is being bound by a sqldatasource. I get the following error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. EDIT: NEVERMIND Egg on my face. I was getting this databind error because I was binding it somewhere else in an effort to troubleshoot my real problem from last friday but I forgot about it.
WHAT MY REAL PROBLEM IS: The usercontrol is getting bound before the properties get set so it appears as if they are never set. When stepping through I see that they get on the property is hit before the set on the property is hit. For example if I put <%# EVal("Address_ID") %> before the user control I will see the ID displayed but then the user control will display an emptydatatemplate because it is being passed the ID of 0.
<asp:SqlDataSource ID="sqlFacilityAddresses" runat="server" DataSourceMode="DataSet" SelectCommandType="StoredProcedure" SelectCommand="SP_Facility_GetAddresses" ConnectionString="<%$ ConnectionStrings:Trustaff_ESig2 %>">

I have created several WPF User Controls. The lowest level item is 'PostItNote.xaml'. Next, I have a 'NotesGroup.xaml' file that has an ItemsControl bound to a List of PostItNotes. Above that, I have a 'ProgrammerControl.xaml' file. Each ProgrammerControl has a grid with four different NotesGroup user controls on it (and each NotesGroup contains 0-many PostItNotes.
Then, I have my main window. It also has an ItemsControl, bound to a list of Programmers.
So, you end up with a high level visual view of a list of programmers, each programmer has four groups of tickets, each group of tickets has many PostItNotes.
The trouble I'm having, is that I want to respond to a mouse click event in my mainWindow's code behind file.
I can add a MouseClick event into my PostItNote.xaml.vb file and that is getting called when the user clicks a PostItNote, and I can re-raise the event; but I can't seem to get the NotesGroup to listen for that event. I'm not sure if that's even the correct approach.
When the user clicks the PostItNote, I'm going to do a bunch of business-logic type stuff that the PostItNote control doesn't have a reference to/doesn't know about it.

auto filling data into webpages. I need to write a server side application mostly a console host app that makes some queries to the SQL Server database and gets a list of lets say students and their grades.There is a third party website that gets updated at the moment some peoples working and filling that data manually.
I need to write a program that will basically open that webpage, login if required, navigate to certain page, click on certain tab, fill the data and hit the submit button. I don't think this part is that hard but the trouble comes with a client side dialog box. At the moment there is a client side dialogbox that shows up when you hit the submit button confirming the action and I need to press OK on that automatically.
I am allowed to write a windows application if not a console application and also use the web browser control to load the webpage rather than opening and interacting with the browser. If this makes it easier than so be it.

I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.

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 quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?
