I need a div element to cause postback to the server. I can use window.location tough but then I think I won't be able to fire any event back on the server. How can I call the asp.net generated dopostback function properly?
View 1 RepliesI've got the following in my .aspx:
<input type="image" src="<%=PayPalButtonImage %>" onserverclick="RedirectToPayPal" runat="server" />
In the code-behind I've got this property:
protected string PayPalButtonImage
{
get { return PayPalExpressCheckoutButtonUrl;}
}
protected void RedirectToPayPal()
{
}
why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :
'ASP.cart_aspx' does not contain a definition for 'RedirectToPayPal' and no extension method 'RedirectToPayPal' accepting a first argument of type 'ASP.cart_aspx' could be found

View 6 RepliesIf I want my button to go to another page instead of going to its own page, I can set the PostBackUrl to destination page.Howevery, I read in microsoft website that Server.Transfer is not good if you are concern with security and permission.Is PostBackUrl the same with Server.Transfer?Does the user will not be authenticated again in the new page?
View 6 RepliesI'm trying to use PostBackUrl on my asp.net form (insert mode) to go back to previous page. I'm hoping to use Request.UrlReferrer.AbsoluteURL or similar.The difficulty I have is how to assign value to link button (called InsertButton) property "PostBackURL".
Some examples show simply InsertButton.PostBackUrl = Request.UrlReferrer.AbsoluteURL but it my case it doesn't recognize the control. I'm using VS 2010 with asp.net 4.0

The OriginalSource property of the object identifies the original object that received/initiated the event. Consider a custom control (called CustomControl1 in this example) that is composed of a TextBlock. When a MouseDown event is raised on the TextBlock, the OriginalSource property will be the TextBlock, but in CustomControl1's handler, the Source will be changed to the CustomControl1 object so that other elements along the event's route will know that CustomControl1 received a MouseDown.
Is there equivalent of WPF OriginalSource event property in Winform and ASP.NET ? If not how to emulate this ?
I've build a custom server control inheriting from WebControl. Basically it is a kind of button. All is working perfectly except one thing: the PostBackUrl is inoperative.
I probably forgot to implement something. Actually I just added the property PostBackUrl. Probably I should also implement an interface of call something.
HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.
When I use an anchor tag on an aspx page as below,
<a href="~/pages/page.aspx?id=<%= ServervariableName %>"> test </a>
it will get the variable value correctly assigned to id but it won't route the page correctly as the ~ will not be evaluated without the runat="server" attribute on the 'a' tag. But once I add the runat server attribute, it does not evaluate the servervariable name anymore.. how this works or what I should do to take care of both?
The AutoPostBack doesn't seem to work. Anything I am leaving out?

Its simple if I have an ASP.net page with an ASP.net linkbutton / hyperlink and I obtain a value from say a SQL Database and I store it in the label...
For example:
this.myLabel.Text = someValueReturnedFromADatabase
This is simple because it goes right to the code behind page and set the text value to the value returned from my database (aside from going into more details with data access layer, etc).
What I was wondering is what if I dont want to use an ASP.net linkbutton and I simply want to use an HTML link button (as I need to call the jquery fade function). How would I set the value someValueReturnedFromADatabase to a control that is not runat=server?
i'm trying make some stuffs in jQuery using asp.net. but the id from runat="server" is not the same as the id used in html.
i'm used to use this to get the id from this situation:
$("#<%=txtTest.ClientID%>").val();
but in this case. it does not work, and i'm clueless why.

View 4 RepliesI have created a new Web project (.Net 3.5) and I've removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:
Error 4 '_Default' does not contain a definition for 'FirstName' and no extension method 'FirstName' accepting a first argument of type '_Default' could be found (are you missing a using directive or an assembly reference?)
My declaration of the control:
<asp:TextBox runat="server" ID="FirstName" />
EDIT
Page declaration:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
Code-behind:string firstname = FirstName.Text;
i had NT authority user account on the web server (or simillar priviallge account with sid like s-1-5-21-1311... ).
recently, due to security issue, had to remove this account and the application hosted on the webserver stopped working.
the issue seems to be with the database connectivity. not able to analyse the issue as, this occuring only on production and not on development server.

I always used <asp:Label to set value by code but i always notice that label converted in runtime to span so i decided to user span by making him runat=server to be accessed by code, so Which is better to use asp:label or span with runat=server?

I've got the ImageButton wrapped inside a form tag with runat="server" but STILL getting this error at runtime. The form tag is at the very beginning (before my table) and end tag is at the end (after the table).

In other words, why can't I do this:

visible=<%= someFunctionWhichEvalsToFalse() ? false : true %>>

It seems to do nothing. I checked this by switching the false and true.

</div>
I have this problem - I'm working on an ASP.NET AJAX-application on a server without .net 3.5 which means I can't use ListView (BOO!).
I decided to simply do the ugly way of making a table and giving the tbody an ID and a runat server tag, and put HtmlControls inside from the codebehind (btw - this is a usercontrol, in case it makes a difference).
This all works fine - until the page does a partial postback - and all the elements disappear, since the tag is runat server I assume it requires to be repopulated in the page load.
Is there no way to actually persist the data on partial postback? And only have the content of the control change when I say so in the back end?
I guess I could save the content in a session object upon populating the control, and just repopulate in the Page_Load with the session object - but I was hoping there was a better way to do this?
Since upgrading to VS2010, I've been having issuse up on issues with my apps. Some are pure asp.net web sites, other are webpats that are eventually be converted to a Sharepoint web part.
In one of these webparts, I'm building a tab control on the fly. It fetches data from the table via bll/dal. On my dev box I build this in the code file of the default.aspx file and rendering it in a panel, except that it get the said error. I'm quite sure this is how I've done it in VS2008, so I don't know what is going on here - see my code below.
