Setting A Server Control Property From The Content Page?
Oct 27, 2010
I need to validate a textbox to ensure the submit date is older than Today. I wanted to use a CompareValidator to do that, but unfortunately the following code doesn't work:
<asp:CompareValidator ID="cvtbDateExpiration" ControlToValidate="tbDateExpiration"
Operator="GreaterThan" Type="Date" ValueToCompare="<%= DateTime.Today %>"
ErrorMessage="Card has expired" runat="server" />
The compiler tells me that ValueToCompare="<%= DateTime.Today %>" is wrong: "This is not scriptlet. Will be output as plain text."
Is there a simple way to achieve this (without setting it using the Code Behind)?

I have a web page (Orders.aspx) that gets some orders and show them in a Gridview .The orders list I get from DB is depend on a field named Status. The page has a master page that contains a Tab user control. The user control has several tabs and every tab has a different Status. Therefor, when the user clicks on every tab, I want to pass a value as status to my content page (Orders.aspx) and then select the orders from DB based on status.

I'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.
[Code]....
how to get around this problem? Is there something I may have missed?
Here's the code for the Control
[Code]....

I am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }
When I add the user control to the page and call it without any properties:
<uc1:Usercontrol ID="uc" runat="server" />
the default values are not set and every property is 0 or null.

I am using Master pages for my ASP.NET website and in one of the content pages I upload a file which requires a bigger timeout value than the default 90 seconds. for other content pages I want to leave the default timeout value as it is. is it possible to set the timeout just for a specific content page? I checked the ScriptManagerProxy component, but it doesn't have this AsyncPostBackTimeout property.

I have a control that I want to be able to mark areas as editable. When a user enters a username and password, they can then edit these editable areas.One of the area to edit is the main content of the page. Since I want them to be able to edit this on every page, I have put the editable control into the master page, wrapped around the ContentPlaceHolder of the master page.I found out how to allow the parser to allow <prefix:tag></prefix:tag> rather than just ending it with />, but I can't figure out how to get the text within the tags to be accessible through something like a Text property. A prime example of this behavior is the Label control, where you can put <asp:Label>Hello!</asp:Label> and access Hello! through the .Text property in the code.

I wanted to have the Editor control without the toolbars and found this guide: [URL]
The guide shows you how to make your own class derived from the Editor class, and gives some overload functions to remove the toolbars, and only have the bold and italics button.
I made my own "customEditorSample.aspx", and was able to reproduce what was in the guide.
However, in customEditorSample.cs, when I try to access the Content property of the control, it won't show up in the intellisense.
When using the regular Editor ajax control, I can save the contents to a label by doing:
Label1.Text = Editor1.Content; and "Content" would appear in the intellisense after typing the period after Editor1.

I wish to set the accept button for each of my content pages. My Master Page login button is set as the accept button somehow. This is fine for the home page, but not the majority of the other 40 pages. All of my website pages are content pages and they are linked to the master page. They don't have forms, just contentplaceholder tags. Does anyone know if there is a way to programaticaly set the accept button in the code behind of a content page?

Just posting this up as I've been searching all over the net for the last few hours and not found anything useful. What I need to do is set the tabindex on a content page so that when using keyboard navigation the form controls in one vertical column are selected first, and then the 2nd column. (rather than one row at a time).
My problem is this means that the "skip to content" and all the other links in the master page are bypassed and the first form control with a tabindex!=0 is jumped to. Is there any way to set the tabindex on a content page relative to the previous tabindex from the masterpage? (when no tabindex is set on the master page).
I was hoping at the top of the content page you could set relativetabindex or something like. we use many different masterpages that change fairly frequently so setting the tab index for every control on the page is a really horrible way to get round this. I'm hoping theres a nice .Net way of doing it and no javascript hacking has to be done!

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.

In a webforms app, I used to be able to access the master page to hide a link as follows through a property...
protected void Page_Load(object sender, EventArgs e)
{
HeaderFooter m = Master as HeaderFooter;
m.ShowHomePageLink = true;
}
However, when I try this in my MVC View, I can access the property but it doesn't hide the link as expected. It's as if the View is already rendered.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<%
MyApp.MasterPages.HeaderFooter m = Master as MyApp.MasterPages.HeaderFooter;
m.ShowHomePageLink = true;
%>
...
</asp:Content>

FROM BOOK: To reference public properties in a master page, we add the @MasterType declaration to the content page and reference the property using Master.<PropertyName>.
QUESTION: But what happens internally? Does all of the master's and content page's properties, function gets complied into one class? Or something else?

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
