How To Put Common LOGIC Control (Like Search/Find) On Each Page
Jan 13, 2011
I'm having trouble figuring out how to do the following:On every page (or every page I so desire), I'd like to put a common control widget (e.g. think - Search functionality that contains a textbox+button). What's the best way to do this, and who handles the submit button (assuming it is a submit button)?i.e. what does my ViewUserControl look like? Does it have a form? does it use jQuery onclick""? Does it post to the main View's action method, or can I redirect it to another Controller/Action

I have a .aspx page in c#. There is an ajax control that shows the data company names from the xml file when the city is selected.
There is also a bing search control on the page.
The issue is that the Ajax control stops populating the data when the search control is present on the page.
The ajax control works absolutely fine when the search control is removed

I was wondering if setting a default value for a SelectList is considered to be presentation logic or business logic? For example, if a requirement is that an Employee cannot be saved without a Location, but 99% of the time the location that would be selected is a particular item -- say Atlanta. Because of this, the location SelectList should be defaulted to Atlanta when ever a entry screen for a new employee is displayed. Should I be defaulting the location in the model or in the view-model? One thing I realized is that the unit tests become awkward because in both cases, I'd be forced to test against a location that will always be present in production but I cannot create a unit test with my own test dataunless "Atlanta" was in the set of locations being used in the test.

My master page looks like:
<head runat="server">
<title>
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
Content pages look like:
<asp:Content ID="TitleContent1"
ContentPlaceHolderID="PageTitlePlaceHolder" runat="Server">
My Page
</asp:Content>
This works by placing the content page specific title on the page ("My Page" in this example). Now I want to add a global prefix to the title in my master page for the site name. So I want:
<head runat="server">
<title>
Example.com:
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
However, when I do this content pages are still rendered without "Example.com" in the tile, it's like it's ignored.
Why is this happening and how can I achieve this?

I've written a web user control which I want to be able to drop into the markup for either aspx pages or other web user controls.I need my user control to be able to easily and efficiently work out if its inside another user control or an aspx page. My initial idea is to do it recursively with checks on the Parent property - continue looking up the nesting hierarchy until I find either a web form or a user control - but I'm not sure this the best way of going about this.

Is there a simple way to find a control in ASP.NET by id (in any nested container)? Other than traversing whole controls tree.
Something like this example:
TextBox tb = new TextBox() { ID = "textboxId"};
panel3.Controls.Add(tb);
And in other method/class:
TextBox nameTextbox = MethodToFindControl("textboxId") as TextBox;

I have a solution I'm working on in VS2010 Professional, using ASP.NET 4.0 with the AJAX Toolkit.This has been working fine, but when I started it up today, I got the runtime exception shown above. This exception occurs on any page with a control from the toolkit.Sometimes when I load a page, I get an exception "Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, ublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified." If I then reload the page (without making any changes), I then get the exception shown in the subject line.I tried dragging an AJAX Toolkit control from the toolbox onto a page, and then deleting it, and that worked - once. The next time I tried the page (or any other), I got the exception again. Dragging a control out didn't help this time.

I am loading a control to a page dynamically with LoadControl("src to file"). In the usercontrol i have a validator and some other controls that i would like to access from my page. I canät get it to work, null pointer exception. Scenario is like this. I have a Edit.aspx page which loads the EditTemplate.ascx usercontroll. I would like to get information or find the controls in the EditTemplate from the Edit.aspx site. I have tried exposing the controls and validators as properties but how do i access them from my Edit.aspx?
Example code:
Edit.aspx, the control is later added into a
Control control = LoadControl("src to ascx");
TemplatePlaceHolder.Controls.Add(control);
EditTemplate.ascx
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="CompanyImageFile" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
CodeBehind
public partial class EditTemplate : System.Web.UI.UserControl, IEditTemplate {
public RequiredFieldValidator Validator {
get { return this.RequiredFieldValidator1; }
set { this.RequiredFieldValidator1 = value; }
}
From the Edit.aspx site i would like to check the validators isValid property. Isvalid is set in a Save method. The save button that saves the template is located in edit.aspx, so the post in done from that page. So the question is how to get a hold of the property from the usercontrol in the edit.aspx page, where and how should this be done?
