I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

View 6 RepliesI'm working on a master page, I right click and add a content page, However now I am missing the code behind. So if I make a default2.aspx there is no default2.cs. I can't figure out what I did, It was functioning perfectly before.
View 3 RepliesI love MVC, coming from WebForms development, but there are things that don't make any sense to me. The "Error executing child handler" occurs anytime a vast number of things happen, for instance. It's very close to a useless message. In order to get the actual cause, I click on Debug/Exceptions and check the "Common Language Runtime Exceptions", and then reload the View. Presto! It shows the cause of the error.
Another thing I'm wondering about today is the FormCollection value of the Html.CheckBoxFor control. Checkboxes in general seem badly designed in html, and MVC didn't improve on it much. When processing a POST, if a regular checkbox isn't checked, it simply won't show up in the list of posted elements. Great. Instead of just grabbing it by name in the FormCollection and testing its value, instead I have to test whether or not it exists in the FormCollection. Not very intuitive. The Html.CheckBoxFor is a variant on the same theme. It always shows up in the FormCollection, but with a similarly non-intuitive return. If it's not checked, it yields a value of 'false', which can simply be converted to boolean and processed as normal. But if it is checked, it returns 'true,false'. Super. Now, instead of converting its value to a boolean directly, I have to test the string returned for the index of 'true' and return that instead.
I find this close to as aggravating as the Linq To Sql Sum() method bug. If I run a Select() method on a given numeric property and run Sum() to add them all together, if an empty result set is returned by the query it throws an exception. Now, if I was looking at a bunch of totals to add together, and none of them had anything entered, what would I write in the sum box? Error? Exception? Nope, it would be zero. I fully understand that if no results were returned then nulls cannot be added, but according to the intitial documentation this method was supposed to return zero in such an instance regardless, because that's just common sense. Enough of that rant. Does anyone know why this return value was chosen for Html.CheckBoxFor?
the page form has a hidden slide-in on click of a div, section allowing the user to 'make a reservation'. The jQuery used to animate the slide works fine, and happens on click on the ticky check-box (id="rescheck"). The problem is, instead of all the fields contained within the hidden div displaying on click of the checkbox, and thus sliding into view along with their labels, only one text field input shows, and nothing else. Checking the source code shows that these missing labels & fields are not even in the source code, dispite being in the page code when viewed (and edited) within MS Visual Studio 2008. As you can see, the fields and their labels seem to just disappear in the browser! I have NO idea whats causing this, and am not sure where to go with it next.
This is my PAGE code, from Visual Studio:
<fieldset id="resreq">
<legend>Make a Reservation?</legend>
<label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label>
<input id="rescheck" type="checkbox" class="rescheck" runat="server" />
<div id="reservationfields">
<div id="res_when">
<div>
<asp:Label ID="lblDate" runat="server" AssociatedControlID="txtDate">On which date would you like us to reserve your table?</asp:Label>
<asp:TextBox ID="txtDate" runat="server" CssClass="res_date" />
</div>
<div>
<asp:Label ID="lblTime" runat="server">and for what time?</asp:Label>
<asp:TextBox ID="txtTime" runat="server" CssClass="res_time" />
</div>
</div><!-- close res_when -->
<div>
<asp:Label ID="lblBranch" runat="server">At which restaurant would you like to make your reservation?</asp:Label>
<asp:DropDownList ID="ddlBranch" runat="server">
<asp:ListItem Text="Select a Restaurant" Value="" />
<asp:ListItem Text="Restaurant 1" Value="Restaurant 1" />
<asp:ListItem Text="Restaurant 2" Value="Restaurant 2" />
</asp:DropDownList>
</div>
<div>
<asp:Label ID="lblPeople" runat="server" AssociatedControlID="txtPeople" Text="Number of Guests:" />
<asp:TextBox ID="txtPeople" runat="server" />
</div>
<div>
<asp:Label ID="lblDOB" runat="server" AssociatedControlID="txtDOB">Date of Birth:</asp:Label>
<asp:TextBox ID="txtDOB" runat="server" />
</div>
</div><!-- close reservation fields -->
</fieldset>
...and this is the Source Code when you 'view source' in the browser:
<fieldset id="resreq">
<legend>Make a Reservation?</legend>
<label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label>
<input name="ctl00$cpcMain$rescheck" type="checkbox" id="ctl00_cpcMain_rescheck" class="rescheck" />
<div id="reservationfields">
<div id="res_when">
<div>
<input name="ctl00$cpcMain$txtDate" type="text" id="ctl00_cpcMain_txtDate" class="res_date" />
</div>
<div>
</div>
</div>
<div>
</div>
<div>
</div>
<div>
<span id="ctl00_cpcMain_rvDOB" style="color:Red;visibility:hidden;">You have entered your Date of Birth incorrectly (dd/mm/yyyy).</span>
</div>
</div><!-- close reservation fields -->
</fieldset>
I am trying to copy code from one project to another. There is one problem however:

I have this C# code in a Razor view:
@(Html.CheckBoxFor<RazorSamplesWeb.Models.SamplesModel>(i => i.IsActive))
I tried translating it to this:
@Code Html.CheckBoxFor(Of RazorSamplesWeb.Models.SamplesModel)(Function(i) i.IsActive)End Code
But it's complaining. Why, and what is the right statement?
In my ASP.NET MVC app I am rendering out a checkbox using the following code:
<%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %>
Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection:
FormValues["ReceiveRSVPNotifications"]
I get the value "true,false". When looking at the rendered out HTML I can see the following:
<input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox">
<input name="ReceiveRSVPNotifications" value="false" type="hidden">
So the FormValues collection seems to join these two values since they have the same name.
figure out the missing codes to get data from database and plot the latest 10 entries to database on the map.
this is the coding i came up with so far

I have web site running in a virtual directory and everything is working great.
I copy the entire contents of the web site to another virtual directory on the same server, but an update panel causes a full page postback in the new site. This is not happening on the original site.
Looking into the rendered page source from the two sites, the one that works includes a script tag link to "Webresource.axd", but that is missing from the page rendered on the new site.
I did the following:
(1) File / New / Web Site
(2) Right-clicked on new website name
(3) Selected "Add New Item..."
(4) Selected Web Form
(5) Didn't see any check boxes for selecting either "Place code in separate file", or "Select master page".
The checkboxes are missing. Is this a configuration problem?

but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.

Anyway i'm using RegularExpressionValidator and CompareValidator to check on textbox errors.
Now when i press a button it will go to my code and i will then try to detect for RegularExpressionValidator or CompareValidator errors by doing:
If not RegularExpressionValidator.IsValid
Now the question is if there is a way to bind the button with the validators so it will not trigger the code if the expressions are wrong.
I would have goggled it but i don't know exactly what to write on the search box.So i get un-useful results.

According to all I've read, the above code should be sufficient. Since CommandName is set to Update, it would seem that no code-behind is necessary.
