Yes it is necessary to install AJAX extensions.
|
|
|
|
|
Ajax should be installed by the person who is maintaining the server. contact contact ftp provider and ask them to install ajex. then it will work.

You mean AJAX extensions, right? AJAX and AJAX server extensions are different.

Seems like you are trying to Register your Client Script in a page where AJAX is enabled. You cannot Call ClientScript.Register.... and Response.Write when PartialRendering is True (i.e in the AJAX page).

System.Timers.Timer myTimer = new System.Timers.Timer();
myTimer.Interval = 1000;

You don't understand how web applications work. There is no state. They are stateless. The page exists only for the briefest moment while the request is handled. After that it is unloaded from memory. Your timer now has nothing to time.

If you wanna use timers, take a look at the AjaxControlToolKit
The have a timercontrol that behaves just like the timer in windows apps

i have a page in which i have property name
public partial class mypage : System.Web.UI.Page
{
private Class1 mclas;
public Class1 Mclas
{
get { return mclas; }
set { mclas = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Mclas = new Class1();
}
}
}
In a user control i want to access this property Mclas
mypage mpage= this.Page;// this doesnt work the it gives compile error the type or namespace mypage couldnot be found
mpage.Mclas
|

|

Try this:
Object X = this.page
Object Variable = X.PropertyName
This will only work if the page containing this control has a property with the name of PropertyName
Look at this VB example:
Inside Control:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim P As Object = Me.Page
Response.Write(P.X())
End Sub
Inside Page
Public ReadOnly Property X()
Get
Return "Something"
End Get
End Property

Create an interface that contains only the properties that you wish to access. Then you have the Page class implement that interface.
Now you can cast the controls' this.Page to the interface, and access you property through it.

Hi,
I have populated a few dropdown boxes in runtime and these boxes are bind to a objectdatasource. When I click the Formview's insert button, it posts back to server, and all the items inside the dropdownboxes are disappearing.
How could I protect the values of these boxes in runtime even post back occurs. I tried to define a conditional statement to control to post back as (if not page.ispostback Then), it didn't work out too. All I need is to have the values for the dropdownboxes regardless of if postback occurs or not.
If you know the answer, would you please let me know.
Thank You.

Doesn't ViewState preserve it automatically?

Thanks for responding. The formview's viewstate is already enabled. I am still looking for a solution.

NO. If OP is creating the control in any event after viewstate is loaded, it's viewstate won't be preserved.
|

Web applications are stateless. When you create dynamic controls, ASP.NET won't be able to maintain it's viewstate. Dynamic controls has to be recreated each time page posts. Use OnInit or any event which fires before viewstate is saved to create your dynamic controls.

Thanks for responding. I never thought that it would be such painfull to deal dynamic controls in asp.net. I placed this dropdownboxes inside the formview and I have populated them in runtime and they are bind to objectdatasource.
The values returns nothing when I try to populate them in Page_Init event. It can't find the control (Formview1.FindControl("GetYear")) returns nothing. OnInit requires an event argument. How coudl you define an event for OnInit inside an aspx page. Would you give me an example.
Thanks.

Hello!
I have seen this problem before and i have not found any better solution than to save the sortexpression value in a session variable.
Every time the sortexpression is not null, save it to the session, and use the session when the sortexpression is null.
somewhere i saw that this is a bug in the gridview that is exposed when you are databinding from codebehind, but it could be a rumor.

Dreamweaver is the web development tool i use, so I guess I should be using php. But from what I heard php and asp.net are similar. I'm more comfortable with the .net suite and I was wondering because of that, should I start doing dhtml in there, or keep with dreamweaver. I mean php can't be that hard, just which one is better overall?

I have a composite server control and I create some dynamic controls in it, like so:
public class MyControl : CompositeControl
{
private Panel panel;
protected override void CreateChildControls()
{
Controls.Clear();
panel = new Panel();
panel.ID = "Panel1";
panel.SkinID = "Panel1"
Controls.Add(panel);
}
protected override void Render(HtmlTextWriter writer)
{
panel.RenderControl(writer);
}
}
The said server control is placed on a page which uses a stylesheet theme, which has a skin file containing a declaration for a Panel skin, like so:
<asp:Panel SkinID="Panel1" runat="server" BackImageUrl="top-panel.gif"></asp:Panel>
However, the skin is never applied... Am I missing something or doing something wrong? Perhaps CreateChildControls override is a bad place to do that?
