I have an HTML page with this script:
<Script>
function Run()
{
alert("The Content Here");
return true;
}
</script>
<button onclick="Run();">I Want It Now</button>
Lets say that I opened this page with firefox or Chrome. And lets say that I clicked on the button "I Want It Now" and the page shows me the alert:
The Content Here
How can I insert the alert content into a string in my VB.NET project? I know that I can use the alert window handle to get the label handle and then extract (grab) the text of the alert, but I don't think that this is the best way to do it. Is there another way to pass (or get) information from the page (not from webbrowser control or by using webClient.DownloadString) into my VB.NET (or C#) project?
i don't this it will easy to use js without the webbrowser control by the way if you changed your mind and want to use a web browser control , you can do it like this :)
WebBrowser1.Document.GetElementById("NAME").InvokeMember("click");

I have a TextBox and and I want to open a Popup on clicking TextBox. There is no Click event for TextBox. I want to do it in C# completely. I don't need jquery in opening Popup on Click of TextBox.
Asp.net textbox:
<asp:textbox onclick="myJavaScriptFunction()" runat="server" id="myTextBox" ... >
#edit
jquery example:
$("#target").click(function() {
alert("Handler for .click() called.");
});
The nature of creating a website solution like you are doing makes this impossible. In ASP.NET WebForms and MVC you do not deliver C# code to the user so you cannot create client side behavior with C#; instead, you deliver an HTML page and assets like files for Javascript, CSS, images, etc. If you want to invoke client side behavior, you need code that will run client side. That means using Javascript, and I recommend that you use jQuery while doing that.
nirmus's answer will give you an example for that, but to answer your question completely bluntly the answer is: "You can't."
I'm using the WebBrowser control and want to bypass a button press on a web page. I'm not very familiar with HTML and web pages, but I'm wondering if anyone has a solution.
The button I'm talking about is on this web page:
http://www.movshare.net/video/ut55cfdvg5wgj/?
The button is appearing at random so it might not be there always.
Edit: Thinking about this, you can do most of this from the C#. Updated.
Get a reference to the button and invoke it's click() JavaScript method:
HtmlElement btn = myBrowserControl.Document.GetElementById("myButton");
/*
Alternatively, take a look at these other methods for retrieving an HtmlElement:
HtmlDocument.GetElementFromPoint(Point point)
HtmlDocument.GetElementsByTagName(string tagName)
HtmlDocument.All.GetElementsByName(string name)
*/
btn.InvokeMember("click");
This will only work in all browsers if ...
Since this is a WebBrowser control, you don't need to worry about cross browser issues.
Do you want the user to skip the button press everytime. Then this means, you don't need the button at all on the page. Please put more information
i have a doubt on how to show a popup???`
if (machineID.Count != 0)
{
checkMachineGrpState(machineID);
}
else
{
FormsAuthentication.SignOut();
Session.Abandon();
Response.Redirect("~/Default.aspx");
}
Ok now what im am doing in else statement is signing out the user and sending him back to the log out page....
I need to how him some pop up message that he is being signed out i cant figure out how to do that...
i tried messagebox but it wont work with servver and client side..
I want to use AJAX but dont know how...
any suggestions.... thanks
There are a couple of different ways you can go about this. Here's a simple example.
Your Default.aspx page will need to display the message to the user when they've logged out, so you might want a way to distinguish when you want to show the message. You could add a query string param to your redirect, like:
Response.Redirect("~/Default.aspx?ShowLogout=true");
Now on your Default.aspx page, you have a number of options. You could simply show a hidden control on the page, or write out some Javascript to show an alert box:
if (!String.IsNullOrEmpty(Request.QueryString["ShowLogout"]))
ClientScript.RegisterStartupScript(this.GetType(), "LogoutMsg", "<script>alert('You have been logged out.');</script>");
This will simply write out a script tag that runs when the user views the page. From here, you can make it more elegant by showing the user a better dialog box. For example, you could use jQuery to create a nice looking dialog box, and call the Javascript function to show it rather than calling alert in my example.
I need to open a new window from code-behind on post-back if a specific radio button is selected.
Is there any way to do this?
Thank you.
You can use RegisterStartupScript to send a window.open script to run once the page has loaded.
However, this will cause the majority of popup blockers to get in your way.
I think this should work ;-)
Add some javascript to your radio button to open a new blank window before you post back. This makes it so popup blockers won't block your popup, since it's opened in response to a users click. See this link for how to do this part.
Then, allow the postback to happen as normal and on page load, register a startup script to tell your already existing window to go to a new url.
String script = "window.open('popupPage.aspx', 'myPopup')";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "someId", script, true);
Note that in javascript, when you call
window.open(url, 'myPopup')
if a window already exists with that name it'll return it instead of creating a new window... So your popup won't get blocked!
You will need to run javascript on postback
Simple sample of RegisterStartupScript:
RegisterStartupScript("id1", "<script type=\"text/javascript\">alert(\"I'm from JavaScript.\");</script>");
New windows can be very sketchy, depending on the content that you need to present you might consider using an in window pop-in if you will. You will avoid pop-up blockers that way. If you can give more details we can give better answers.
I am designing a winforms based testing app (which is based upon WatiN). I specify a page to test and the value to insert into a textbox, and then click the corresponding button.
Is it possible to add a query string to the request I make (when clicking button) and then get the URL of the next page? Based on this, I need to screen scrape it.
Not sure about Watin syntax, but in Watir (Ruby version) you can get URL of the page displayed in browser with
browser.url
Or do you need to get URL of the next page before you open it?
Based on your comment to AmitK, Ċ½eljko's answer is right.
In WatiN (and C#), the syntax is:
Console.WriteLine("The current page is:" + ie.Url.ToString());
(just in case: 'ie' is the browser reference, use whatever object you use to enter text and click buttons)
What exactly do you mean by "next page" ? Does the form when submitted redirect to another page? If so, you will receive a HTTP 302/303 status code with the URL of the next page.
