Web Forms :: Access Div From Code Behind?
Feb 9, 2011
I am dynamically creating div tags in my code behind and adding code into the innerHTML property of the div tag and then rendering out the html to replace values inside of a table structure that I have, I then place all the table code onto the page. I want to be able to access the div tags again from the code behind, but can't seem to because well obviously they aren't set to runat="server". Is there any way to do this or to set them so they can runat server.

I have been asked to support a legacy app and I can't get access to the code behind files. I need to add a new feature that gets a list of items from the database on page_load, what way would adding an "in-page" page_load affect the compiled page_load?

I have a 2 textboxes in a Login View on my Content Page (login.aspx) and Login Button outside of Login View. I want to pass the values of those textboxes to the members of class when user hit Login button.
I have User.cs class which contains TxtLogin and StrLogin.
[Code]...
When I debug the program and enter correct username and password it should show me "Thank you" rather than it is showing me "Enter valid Username and Password".

I have a Web Site project running on VD2008, with an Access back end and .NET 3.5, C#.
I have created the project several times and added the usual App_Code, Pages, App_Data, Properties, folders. I created a Master Page and several content pages BUT I am unable to get to the folders or root where there is a Class (code) file.
I have tried all the usual lines...
using SumaCard.App_Code
OR
SumaCard.App_Code.FTP_Code ftpc = new SumaCard.App_Code.FTP_Code();
but nothing works? I have been hasseling over this for 2 days now.
What have I missed? Maybe I built the project wrongly? (Project | New Project | Visual C# | Web | ASP.NET Web Application |??

I have an asp.net 3.5 WebSite application where I have a bunch of UserControls.
In some scenarios I have a reference of type Control (System.Web.UI.Control) that I need to cast to a specific User Control type (to access public properties and methods of the User Control).
The User Control classes are all declared in "the global scope", i.e. not within a namespace. However, for some reason, only some of my User Controls is possible to type in a code file and show up in intellisense and some just wont. In one scenario I could write the cast in code anyway and the site would build (but the UserControl type name did not shift in to the ordinary class name color (light green, you know) in VS text editor), but when running the page I still get the error message about missing using directive or a reference...
If I use the VS 2010 "Navigate to" feature (Ctrl+,) and search for a type I usually get one hit for the Type/Class name and another for the actual file. When searching on my User Control class names I only get the file hits, no class representation. This even goes for those User Control types I actually can access in code.
I've tried to compare the User Control classes that work and doesn't work, but I can't find any difference, they are all declared as public partial.

I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?
My html control is very simple: <input type=text>
But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.

I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value
why is the value null on the content page?

I want to access my checkbox in code behind. I have my checkbox in my aspx file like this:
[Code]....
And i'm trying to set the checkbox visible=false like this but it's not working. Error message: Object reference not set to an instance of an object.
[Code]....
This is just one thing i want to do with my controls in my datalist, so i don't want to in my aspx file like this:
<asp:CheckBox ID="CheckBox1" runat="server" Visible='<%# if(Eval("isFolder")="1","false","true") %>' />
Because i have quite a lot of things i would like to do in the code behind when i'm getting my files..
Is it possible somehow to achieve this without having to put servercode in my aspx file?
