Web Forms :: User Control's Contents Not Created?
Jul 9, 2010
I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.

I have a dynamically created address user control (on a customer administration screen) that is created through the use of a place holder. A customer can have multiple addresses, so they dynamically dropped onto the page.
I have got this far, but now I need to be able to save the updated addresses for the customer but I can't get any event to fire on the user controls. When I check to see run plhAddress.HasControls() it returns false?
The way I am generating the user controls is as follows.. private UserControl LoadControl(string UserControlPath, params object[] constructorParameters)

I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.
<asp:Button
ID="StepNextButton"
runat="server"
CommandName="MoveNext"
OnClientClick="ShowMP();"
align="middle"
CausesValidation="True"
Text="Submit
my Profile"
/>
aspx
<asp:CheckBox ID="Terms" runat="server" />
<asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."></asp:CustomValidator>
Javascript
<script language="javascript" type="text/javascript">
function ValidateTandCs(source, args)
{
args.IsValid = document.getElementById('<%= Terms.ClientID %>').checked;
}
</script>

I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.

I have the membership provider and the create user with tow steps, one of the steps contains a custom registration form, for each created user data will be in the database, and there is an account page shows the data that the new created user did insert during the registration process on the custom registration page,
the problem, when the user is created and logged into his account page, this account page shows only the information for the first created user, not the info on the logged in user , but the logged in user data still saved in database and not showing on his account page?
This is web.confg code:
<?xml version="1.0"?>

Our application lets the administrator create new users. Since the administrator is logged in, I have set Logincreateduser = false so that the administrator is not logged out even after creating the new user.
The problem is :I need the userid of the newly created user to store additional details of the user in another database table. I see that i can get the username using Createuserwizard1.username; but how do I get the userID?

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

I'm using the following code to pick up the UserID of newly created users in a page containing a CreateUserWizard. Should work because it's at the end of the _CreatedUser event, but the UserName comes up Nothing. Anyone know what the problem might be? I know the user is being created because the "success" message is displayed and it writes to the database.

I'm attempting to change my select statement when a selection of "Other" is detected. The problem is that the select that executes on the page is always the original selection from the datasource definition. I've found an example where the "SelectCommand" value is changed in the code behind, but it is for a case where the dropdownlist is not in a template. I'm thinking that I have to bind to the template, but I'm not getting it to work. (see the last couple of lines in the Page_Load code)
asp code:
<div>
<asp:DetailsView AutoGenerateRows="False" DataKeyNames="EmployeeTimeId" DataSourceID="sdsEmpTimeDetailsView"
DefaultMode="Insert" HeaderText="Add EmployeeTime"
runat="server"
AutoGenerateInsertButton="True"

I'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv. What is the best way to approach this? Can it be done client-side with Javascript?
