Populate TextBox From Public Property From Code Behind?
Jul 12, 2010
I am trying to use a property from the code-behind to populate a textbox instead of using in the code-behind textbox.text=. I am using vb.net. Here is the code for the aspx page:
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.
Im trying to learning asp.net & c# and am working through a tutorial that asks me to:
"Add 9 public properties of type TextBox to the code-behind file. There should be one public property for each TextBox control on the page. Each property should have only a get accessor that simply returns the TextBox object that it corresponds to." Ive added code below but im not really sure if what ive added is what is asked for,
So I have this object I'm creating, just to hold some string and boolean data that I want to pass to the second page. So I have a class file:
[Code]....
[Code]....
And I'm setting values from form controls, like this:
[Code]....
So here is the really weird part: if I try to set a label's text property equal to objPrimaryScreeningData.myMemberVariable after selecting it - there is nothing there. I'm sure it's a stupid mistake - being self taught stinks.
I am trying to declare a public property and access it from another page. I can't seem to be able to declare it. I'be tried putting in the code behind but it gives me errors.
I have a property on my Global.asax.cs class that I need to access from a business class, i.e. using HttpContext.Current. How do I do this? Global.asax.cs (in a web project)
public partial class Global : System.Web.HttpApplication { public static ProxyGenerator Generator = new ProxyGenerator(); Business class (in a separate business project) var generator = ((Sei.Osp.Web.Global)HttpContext.Current.ApplicationInstance)
This obviously doesn't work and I don't want to reference the whole web project in the business project as it will create a circular reference (the business project is already referenced in the web project)
UPDATE:
To clarify - the property I'm creating holds an instance of the Castle Dynamic Proxy Generator class. I've read that you shouldn't just create this all over the place. So I thought I'd create it in my Global.asax.cs and then just use that instance wherever I need to create a proxy class (I'm using it to do AOP) Is there a better way of doing this?
I have created a very simple calendar user control that contains a public property which is used to define which month/year to display. My calendar control is placed inside another ascx control (the wrapper control essentially), which includes LinkButton controls used to toggle the calendar control forward and backward one month at a time.
If I explicitly define the SelectedDateTime property of the calendar control in the wrapper control at design time, the proper month/year are displayed by the calendar control. However, when I try to set the property value at run time using a Click event on the previous and next LinkButton controls, the calendar control never picks up the new SelectedDateTime value I try to assign to it.
When I run the code in debug mode, the Click event of the LinkButton always happens last - after the value of the SelectedDateTime property of the calendar control has already been set to default and rendered. What am I missing?
The calendar control is placed in the wrapper control just like any old control:
My project is developed in asp.net 2.0 and uses the System.Web.Extensions.dll in it. The project was working fine earlier. One of my collegue installed the Ajax Minifier in the system and after that an error is triggerred from my application: Type 'System.Web.UI.ScriptManager' does not have a public property named 'LoadScriptsBeforeUI'.I have modified the web.config and tried several options. But, didn't solved the issue.
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
In this case I use a datasource control for a datalist and the parameter list is being built ba the system. The DBType is created for the smalldatetime feild
I have a problem to pass along public variables from C# code to the HTML code. I assign the variables in the Page_Load event and then pass along them to the Panel and Image control in the HTML code. Though I get this compileerror for the Width: "Cannot create an object of type "System.Web.UI.EbControls.Unit" from its string representation '<%setWidthImage%>' for the 'Width' property."
I'd like to know how to declare a variable in my code behind page that I can use in all the subs of my code behind.
I tried in after the Partial Class declaration to declare a "Public String" :
[Code]....
and to use it in my subs but when I use it from a sub to another I loose the value affected in another sub.
Is there a way to use a Public variable from a sub to another (I'm actually using a session variable in order to do it and I'm not sure it is the best way)
I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices, based off of that enum. But I'd like it to pull records from a database and populate the list of choices for the property from a database. This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.
Im a fan of the EF code first and with its last preview of the CTP5 I wonder if it would be safe for me to use this for a smaller site for customer? I would love to get your opinions on this? And any good sources for tutorials and information would be sweet. I'm currently reading the post on scottgu's blog about it.
I created a webpage names Default.aspx. In its code behind i defined another public class named Test. Test class is not accessible in other pages code behind although it is defined as public.
