View 7 Repliesi have this question i was trying to find a way to call a javascript function from asp controllers and i did here is the code :
<script type="text/javascript">

alert("hello world")
[Code]....
and i want to call it from a javascript function so it will be like controller----call---> javascript ---call--->code behind
I have a VB.NET function which looks like this:
<WebMethod()> _
Public Shared Function AuthenticateUser(ByVal UserInfo As String, ByVal Password As String) As Boolean
Dim UserName As String
[code]....
It calls the function, but won't return a value. When walking through the code, my VB function does fire (it will return true so long as the correct password is typed in), but the javascript 'authenticated' value remains 'undefined'. It's like you can't return values from VB functions to javascript.
I also tried
if PageMethods.AuthenticateUser("UserName", "Password")
{
//Stuff
}
But still no luck.
I am calling a javascript in the onclick event in ASP.NET sourcecode, as follows:

Is there some kind of security on IE to that is preventing the download? Are there any solutions or best practices for downloading click once applications from javascript?

I want to calling a javascript function from a asp.net modal window using vb. The javascript function is to close the same modal window. The function I want call is: function CloseModalWindow(winName)

I'm trying to do something which i am not sure is possible, im hoping someone will be able to prove me wrong.I have a desktop application written in VB .net which needs to post to google analytics, the interface they provide is javascript based. At the moment my application opens an internet browser, goes to a specified URL which in turn executes the javascript contained within, this is cludgey and memory gobling!
Is there any way of importing a javascript file and calling a javascript function without opening a third party browser? would preferably not want to use the browser control either.Is there a way of instantiating for instance a javascript engine and passing it the commands?
Say I have a simple web app written in asp.net/vb.net. The web page has one button. When you click it, it does some junk in the code behind. What I would like to do, is when the page reloads, after the server has done its thing, to execute a JavaScript function.
Now the only stipulation is that it can only happen if the button was clicked. Not just on any page load. Is there a simple way to do this?
how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx. The call should cause a postback because i need the usercontrol to display the changes. i am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event.

I have web page with four grid views. Each grid is hidden under a div tag. Whenever user clicks on div the data grid corresponding to the div is shown. I have binded data to the grid views at the page load only, since the data size is huge I cannot load the data binding at the page as the time taking to page load is huge. I was thinking a way that grid view gets data loaded only when user clicks on the corresponding div tag
View 2 Repliesi am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this stupid question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e)
{
Label3.Text = "this is label three";

I need to open a popup window from a LinkButton which is inside a GridView within an Update panel
I call this code in grid view's RowCommand
Dim script As String = "window.open('PopupPage.aspx, 'CommentsView', 'top=150,left=100,menubar=no,width=780,height=400,toolbar=no,resizable=no,scrollbars=yes');"
ScriptManager.RegisterClientScriptBlock(Me.Page, Me.GetType, Guid.NewGuid().ToString(), script, True)
But it does not open the popup window nor it gives an error, How can I fix this?
How can I call a javascript function from code behind?The most popular response is "ScriptManager.RegisterStartupScript" however, that does not work in my situation. I have a vb class that is doing a database check to see if a record exists. If exists, then call a javascript function to display an alert("Record exists") So I am doing something like
Dim strMessage as string = "javascript:RecordExists('Param');"
How do I call this function from my vb.net class?

View 3 RepliesI can call C code from Visual Basic by compiling that C code into DLL's.
1. Does it have to built in Microsoft Visual? Or is something built with MinGW okay?
2. How do I add it into my VB project?
3. How do I actually make the function call? (given that VB and C syntax obviously have some differences)
I have built a web browser and my new window function is working great, it allows me to open popups that use normal https links without a hassle. But I am having some problems when the links contain java code (like the one below:
("javascript:var%20x=window.open('https://auth.det.nsw.edu.au/pls/orasso/orasso.wwsso_app_admin.fapp_process_login?p_app_id=F0CB644DAE48EDE00D83EFE378FD435E','My_Staff_Email','menu=no,toolbar=no,resizable=yes,scrollbars=yes,status=yes')"
The reason why this operation fails because the string that is being passed to the Navigate method is not an actual URL.It is apiece of Javascript code which needs Javascript engine to process it firstly. Apparently, Webbrowser.Navigate() does not have this functionality,so it fails. If you simply put the string in IE�s address bar and press enter, IE will also not able to open it. The reason why it does work if you access the HTML page in IE and click the hype link is because this will make IE to use Javascript engine to process the code.
Since the API(Webbrowser.Navigate) does not have the functionality to process Javascript code,build up my own code to process the string which you get by using the GetAttribute method. The code reads the string and finds the actual URL and passes it to the Navigate method.
The only problem is that the javascript code constantly changes (varies upon what link is opening) and the url itself will change depending on what the link is linking to! Below is the code that I use at the moment to get the full link .finding the actual URL in the javascript even with the javascript differing from link to link).
Dim myElement As HtmlElement = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Document.ActiveElement
Dim address As String = myElement.GetAttribute("href")

In my project, there are 3 user controls; BasicContact, BasicDetail and ActionTime. They are in EditOrder.aspx page. There is "ReportDate" property (Date type) in BasicContact, RadioButtonList "rdl_Priority" (with integer value from "prio_id" field) in BasicDetail and "CheckDate" property in ActionTime. The ReportDate value is derived from txt_ReportDate and txt_ReportTime and CheckDate value is derived from txt_CheckDate and txt_CheckTime.

<script type="text/javascript">
function openWindow(url) {
document.forms[0].target = "_blank";
