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,
[Code]....
public static string SEARCH_STRING = "searchkey";
string key=Request.QueryString.Get(SEARCH_STRING);
How to change the above code to make SEARCH_STRING be accessed using a Property(get; set;) instead of a public variable
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 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:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">
<asp:TextBox runat="server" ID="roleTextBox" Text='<%# CurrentRole.Name%>'></asp:TextBox>
</asp:Content>
Here is the code behind code:
[Code]....
When I run the page the text box is empty.
I have this public property in the codefile of an aspx page:
[Code]....
Then in that aspx page I have a usercontrol (.ascx), how can I access the above public property form its codebehind?
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.
View 2 RepliesI 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?
<asp:TextBox ID="TextBox2" runat="server" Width="118px" ontextchanged="TextBox2_TextChanged" TodaysDateFormat="dd/MM/yyyy"></asp:TextBox> <ajaxToolkit:CalendarExtender ID="TextBox2_CalendarExtender" runat="server" Enabled="True" PopupButtonID="ib1" TargetControlID="TextBox2" DaysModeTitleFormat="dd/MM/yyyy" Format="dd/MM/yyyy" > </ajaxToolkit:CalendarExtender>
ajaxcontroltoolkit.calendarextender' does not have a public property named 'DaysModeTitleFormat'
How it will be removed??????
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:

I have made public readonly shared properties in my class.
I want to acces a property's value in .aspx page. As i think that is possible through scriptlet like this
<%= ClassName.Propertyname %>
But its not working .Where i am wrong ?
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.
View 2 RepliesHow can one access public property of User Control In Master Page on child Pages.
View 1 Repliesto whom it may concern,
I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is
((CompanyWide)this.Master.Page.Master).HtmlTitle = "now it is working";
i dont want to use "MasterType" i would rather cast..
I have user control in the master page. user control code behind page having public property called SetValue.
Now I want to set the value from content page .
I had to format my hard disk and reinstall the Visual Studio 2005 Enterprise and SQL 2005 Standardprograms.
While my program worked perfectly before and still works ok on my second computer, I get the following error message on the formated computer:
Parser Error Message: Type 'System.Web.UI.WebControls.Parameter' does not have a public property named 'DbType'.
Source Error:
Line 82: <asp:Parameter Name="Olho" Type="String" />
Line 83: <asp:Parameter Name="image" Type="String" />
Line 84: <asp:Parameter DbType="Date" Name="inicio" />
Line 85: <asp:Parameter DbType="Date" Name="termino" />
Line 86: <asp:Parameter Name="pageId" Type="Int32" />
Source File: /0_oserigrafico/Default.aspx Line: 84
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
how do I add the property named 'DbType'.
I can access a module from code behind but not from the aspx page in inline VB code <% ... %>.
I know its got to be something simple but I can't seem to find the answer anywhere.

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>.

So what I'm trying to accomplish is this

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.
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.

As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.
Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?
