On the me.LoadComplete event of my webpage, I am creating buttons dynamically from session arrays. After I add each button control to the page, I want to use the addhandler to call a custom sub I made. When I click any button though, nothing happens. Relevant code is below.

Provided wsdl from link below:
http://www.2shared.com/file/zfTUDRl3/poccrm.html
I've been given merely a wsdl above from client, without any further information given, to make a call using c# code but i added as web reference, used the codes below and the client side detected my request and they've returned us proper format xml too, but i cant retrieve it in the string array from the method returned. the "stringset" has became null instead of array[10]. Can anyone give a hint what kind of web service call is it, since it is not using the simple and classic way to invoke?
static void Main(string[] args)
{
//added web reference for wsdl as poccrm
string[] stringset = new string[10];
poccrm.poclib caller = new ConsoleApplication1.poccrm.poclib();
poccrm.SE1I2001 callerItem = new poccrm.SE1I2001();
callerItem.AcctNo = "0010241000007914";
callerItem.TransNo = "12345678901234567890";
callerItem.StartDate = "20-01-2010";
stringset = caller.SE1I2001(callerItem); //here i get null for stringset, but client received the request and returned us value
//same result even I use wsdl.exe converted it to a class file
/*
string[] stringset = new string[10];
poclib caller = new poclib();
SU1I1001 callerItem = new SU1I1001();
callerItem.AcctNo = "0010029004000370";
callerItem.transno = "12345678901234567890";
caller.end
stringset = caller.SU1I1001(callerItem);

View 1 RepliesI have the following in an aspx page:
<td colspan="2">
<% DisplayParties(); %>
</td>
In the code behind for the aspx page, i have this (e.g. I build HTML for the checkboxes):
[code]....
Not my proudest moment, but whatever. The problem is that when this page posts back via some event on the page, I never get these tags in the Request.Form collection.
Is this simply how ASP.NET works (e.g. only server-side control post back) or am I missing something simple.
I have a login ascx module that needs to handle logged in users.
I am solving this by enabling Session("IdUser") to take Id_User from my database if login and password are correct.
Ok, this works rather OK, but I am using the same button for login and logout, so when I login user I need manualy to reload the page before handler me.load have new values for current session, does anybody know how I can solve this isue.

I have created TextBox dynamically, and i need to makd AddHandler on lostfocus event. If i use AddHandler Textb.TextChanged, AddressOf TxtBox_OnChange it work well, but i am passing the textbox value from javascript (popup window) so it is not recognizing the textchange. and if i enter the text by keyboard then TextChanged is calling the the function well. how i can call TxtBox_OnChange on lostfocus on the TextBox.
View 3 RepliesI have created my own custom role provider class "SGI_RoleProvider" and configured properly.
Everything is working fine.
Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error.
how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless.
I've added AddHandler to dynamic controls in code behind but when I (for example) select an item from the ajax combobox (selectedIndedChanged) nothing happens.
Code Behind Sample:

in datalist templatefield, i want to bind an imagebutton's visible property. the scenario is .. it is a picture comments page like one in facebook. if its your own comment, the delete button is shown, otherwise not. the problem is .. for the imagebutton i want to set visible = false, if the user logged in is the same user as the one who commented. how can i do that ?
currently im using this code on datalist databind event. but the label is returned as null
public bool set_visibility()
{
Label lb = DataList3.FindControl("Label7") as Label;
if (lb.Text == Session["user_id"].ToString())
return true;
else
return false;
}
findcontrol dosent return the control.
How to call a custom control when query string is changed?
My example not work?Why?
[Code]....
I've been trying how to make a dynamic controls in ASP.Net and figured out that it was the same on VB.Net like this.
Code:
Dim objCheck As New Checkbox
With objCheck
.Name = ""
The only difference is that instead of "Name" that should be "ID" and "Location" should be "Attribute("style") = "top:100px; left:100px".
Now I'm getting this error saying that "it should be place in a form tag and runat="server"".
BTW, that adding of dynamic controls is place in Page_Load()
Secondly how to add an AddHandler of that newly added control ?
I have an ASP.NET page with code-behind in VB.NET. On the ASPX page I have a Repeater with an asp:ImageButton inside the repeater and I want to catch the clicks on the button. As far as I read I have to use FindControl and then handle the copy of the original control:
Codebehind:
Dim imagebutton1 As ImageButton = repeater.FindControl("btnImage1")
AddHandler imagebutton1.Command, AddressOf ReportTransfer
...
...
Protected Sub ReportTransfer(ByVal sender As ImageButton, ByVal args As CommandEventArgs)
...
End Sub
ASPX page:
<td>
<asp:ImageButton runat="server" ID="btnImage1" ImageUrl="~/images/icons/icon_small.png"
CommandArgument="3" />
</td>
</tr>
</ItemTemplate>
It throws "Object reference not set to an instance of an object" on the AddHandler line and I have no idea why it is doing it (I'm a bit new with VB.NET)
I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?
View 1 RepliesI have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
On the page load i wanna call a custom validator which validates my page and display corresponding error messages.
How can i do this?
I am using javascript in the custom validator.
I have created thread pool which have 5 threads. Both of them will start when my application start up. The problem is I created so many objects in thread loop call back function on each threads, and the memory is increase by second when app running, this is thread loop call back function:
void ThreadLoop(){
while(true){
var checkItems = _workItems.Where(w=>w.ActivedTime > 3).ToList();
foreach(var i in checkItems){
_workItems[i.Id].ActivedTime = 0;
_workItems[i.Id].ExecutePostBack();
}
//Recreate new _workItems dictionary
_workItems = _workItems.Where(w=>w.ActivedTime > 0).ToDictionary();
// Sleep thread to free up momory
Thread.Sleep(1000);
// Call Grab collector free memory
GC.Collect();
}
}
I'm confusing that, is calling GC.Collect() on each threads like that good or bad ? Dose it cause bad performence ?
I have a web service with the following contract:
POST /Service/service.asmx HTTP/1.1
Host: xxx.xxx.xxx
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "xxx.xxx.xxx/Service/Method"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<Request xmlns="xxx.xxx.xxx/Service/">
<transactiontype>string</transactiontype>
<username>string</username>
<password>string</password>
</Request>
</soap:Header>
<soap:Body>
<Method xmlns="xxx.xxx.xxx/Service/">
<xml>xml</xml>
</Method>
</soap:Body>
</soap:Envelope>
And I am trying to call the service using jquery. This is my code:
$.ajax({
url: serverUrl + 'Method',
type: "POST",
dataType: "xml",
data: { xml: "xml" },
beforeSend: function (req) {
req.setRequestHeader('Header', '<Request xmlns="xxx.xxx.xxx/Service/">'
+'<transactiontype>4</transactiontype>'
+'<agencyName>name</agencyName>'
+'<username>user</username>'
+'<password>pass</password>'
+'</Request>');
},
success: function (data) {
alert(data.text);
},
error: function (request, status, errorThrown) {
alert(status);
}
});
However, the header content is not passed to the web service? How would I go about passing the header credentials to my web service call?
I'm trying to write a controller method that returns an ActionResult.
In this method, i would like to:
1. call an HTML helper method
2. Capture and store the HTML helper's rendered HTML in a string
3. Return the method with the rendered HTML wrapped as a JSON
How do i call the Html Helper method from my controller method? Simply using the static class HtmlHelper does not work.
Can I call Ajax.BeginFrom from a custom helper method ?
AjaxHelper is not available in a custom helper method, so I tried to pass the "Ajax" available in ViewPage to Helper method while calling it, but then in method, BeginForm is not available on that passed "Ajax" parameter.
is it possible to call a custom method or class before accessing webmethod from pageMethods ?
View 2 RepliesI'm making a custom modal popup using a bunch divs where the programmer can set how many buttons thay want to apprear on said popup programatically using a function. It works. The only problem is that when the programmer specifies the number of buttons he/she wants it wipes out the skin information for the whole control. If I comment out the call to CreateChildControls the skin works fine, but the new buttons are not created.
In my CreateChildControls function the first thing it does is call Controls.Clear(). I assume this is what's wiping out the skin information, but it's kind of necessary to prevent controls with duplicate IDs.
