C# - User Control Losing State

Jun 27, 2010

I have a user control that I am explicitly calling from an aspx page. In page_load of the aspx page I have the following: myControl = (DynamicTable)Page.LoadControl("../inc/DynamicTable.ascx");

Then in my code where I want it to execute the control, I have this: pnlESDDEnrolled.Controls.Add(myControl);

where pnlESDDEnrolled is the panel I am loading it into for display. So, I execute the aspx page, it links off to the user control, populates the control, returns back to the aspx page and the page displays with the user control in the middle of it. All is well.

The problem comes in when updates are made on the user control. Keep in mind, that other data is updated on the page as well, and the update button resides on the page, not the control. Anyway, when the update button is pushed, the button_click event is fired on the page, but the updates that I made on the user control are lost. Since the page loaded the user control and then the usercontrol executed the page unload method, the page has no knowledge of the user control anymore. Thus, when the update button on the page is pushed, I guess I am not really sure what happens with the updated data on the user control. All I know is that it is lost.

UI Pattern To Allow User To Add Item With Unlimited Sub-items?

Jul 19, 2010

I'm writing an ASP.NET app. I need to include a page where the user can add an item which has several sets of subitems, each of which sets is unlimited in number. The subitems themselves contain between 10 and 15 fields, so need a fair bit of UI space.

As an example of what I mean, the user needs to be able to add a Business record to the system, including any number of Employee records and any number of Asset records.

The way I normally do this is by using a MultiView control with a set of tabs at the top. The tabs switch between the Views of the MultiView. The first tab will be for the Business record, the second will be for Employee records, and the third for Asset records. The Views for Employees and Assets are initially empty bar a button to add a new Employee (or Asset). When this button is clicked, the page is posted back and a user control is added dynamically to capture the details of the Employee (or Asset).

There is one save button that saves the whole object graph to the database.

This is quite complicated to program and maintain and I usually encounter headaches to do with managing ViewState for the dynamic user controls. Obviously, the ViewState on the page can also become quite large, making the page quite slow.

The advantage is that it is quite an intuitive UI for the user to understand, and the user can add everything and check it all before saving anything to the database.

Forms Data :: Losing Data On GridView Control

Oct 5, 2010

I have a page I use to update a student's personal and grade information. I use a formview control to enter and update a students personal information. I use a gridview control to enter and update the student's grades. When the user wants to make edits to the data, they make the changes in the formview and the gridview, then press a "Save" button, which runs code behind that reads the formview and gridview data, builds two SQL UPDATE statements, then performs the update on two SQL tables (the Students table and the Grades table). This seems to work fine in most cases.

Losing User Roles?

Aug 11, 2010

I am baffled, I am using a treeview to set the source of an iframe. The web page is being displayed correctly, but User.IsInRole("roleName"), in the code behind, always returns false. The strange thing is User.Identity.Name returns the correct user name. I have tried setting the target of the tree view nodes to "_blank" and to "_self" and still no luck. So, it doesn't appear that the problem is related to the iframe.Before the treeview was added, javascript was used to set the source for the iframe and User.IsInRole returned the correct values.

Web Forms :: Create Web User Control Dynamically?

Mar 13, 2010

I want to know how can we create web user control dynamically.

Scenario: Basically i am developing registration user control. I have a web page(say, SelectInputs.aspx) that lists different types of fields along with checkbox attached to each of them for selection. Once i select desired input controls (which should appear in user control) and click submit button then the file (.ascx) should be created from code behind.

eg: Lets say on SelectInputs.aspx i select fields viz. Firstname(textbox), Lastname(textbox), DateOfBirth(3 dropdowns) etc and click on submit button then from code behind the .ascx file should be generated that will include Firstname(textbox), Lastname(textbox), DateOfBirth(3 dropdowns) etc.

Web Forms :: Create User Control Class That Extend Panel?

Aug 31, 2010

I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.

So, I create something like this:

[Code]....

And then, in the ClickPanel.ascx.cs file:

[Code]....

I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.

The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.

AJAX :: How To Get An Array Of All The Textbox Control Inside Create User Wizard Control

How can I get all the textboxes inside a create user wizard control using getElementsByTagName().

Below is my JQuery code:

[Code]....

The above code isn't displaying hint text when the textbox retreives focus.

I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .

But no one of them gets the textboxes array.

Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

How To Create A User Control

Feb 11, 2010

I know how to use ITemplate to create a user control where it looks something like this:

<cust:control id="" runat="server">
<template>
random content...
</template>
</cust:control>

however, i am wanting to make a menu like control, and need a more specific setup. i dont need a template section, however, i want to create something where the user control can have only certain elements (which are also user controls). the best way to describe this is by example i think. this is what i want to create for my user control template:

<cust:control id="" runat="server">
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
</cust:control>

the outer control is a user control, and inside its tags it can have other user controls (limited to what is defined in the outer controls code). all of the 'children' in the outer control would then be rendered on the outer controls page markup as if it were templated.
