I have opened a website using WebBrowser. Now I would like to programmatically click input text (textbox) field. I can not use focus because this website uses JS to unlock this field only if it's clicked and I've tried also this:
Object obj = ele.DomElement;
System.Reflection.MethodInfo mi = obj.GetType().GetMethod("click");
mi.Invoke(obj, new object[0]);
But it returns mi = null. How to do this so it will work?
Very similar to my answer on your other question.
Get an HtmlElement respresentative of your textbox, and call HtmlElement.InvokeMember("click") on it.
If you can, use:
webbrowser1.Navigate("javascript:document.forms[0].submit()")
or something similar. For me, it's been much easier and more accurate.
To fill-up a text field on a webpage:
string code ="";
code = code + "var MyVar=document.getElementById('tbxFieldNameOnWebPage');if(MyVar != null) MyVar.value = 'SOMEVALUE';";
domDocument.parentWindow.execScript(code, "JScript");
Then To Click a button on a webpage:
code = "";
code = "var SignupFree = document.getElementsByTagName('button')[1];";
code = (code + " SignupFree.click();");
domDocument.parentWindow.execScript(code, "JScript");
you can also use document.getElementById('buttonID'); instead of document.getElementsByTagName('button')[1]; but an id must be provided for this button on that particular webpage.
Use InvokeMethhod on HtmlElement or Browser.InvokeScript function.

How I can click buttons with ids or anything other, input to text box string etc. I know in windows form is easy with getelementbyid. But in WPF I cant find anything. I know how get source to string but I cant make click. Any ideas how do this or is even possible? I can get list of Ids from source +regex. Or is there too something I can get simply list? Need something like this:
HtmlElement button = webBrowser1.Document.GetElementById("lButtonSearch");
button.Click += new HtmlElementEventHandler(GotoSearchPage);
I can do something like this but what next, how display it?
System.Windows.Forms.WebBrowser weba = newSystem.Windows.Forms.WebBrowser();
weba.Navigate(new Uri("www.google.com"));
string testowo = "btnI";
System.Windows.Forms.HtmlElement htmlElement = weba.Document.GetElementById(testowo);
htmlElement.InvokeMember("click");
How now convert it to display lets say WebBrowser id is =browserwindows
browserwindow=weba
wont work
Try this:
var doc = webBrowser1.Document as IHTMLDocument2;
var button = doc.all.OfType<IHTMLInputElement>().FirstOrDefault(b => b.name == "btnG");
if(button != null)
{
((IHTMLElement)button).click();
}
I have ASP.Net application that have multiple User Controls in the same page every one have its hidden field that holds a value, and every one have button that calls pop-up and through this value from hidden field to it.
The problem that when i try to access the hidden field and get the value inside , the program always get the last one (which created last).
How can i get the value of the inner hidden field in the current UserControl (Which i'm clicking the button from)?
Attempts:
var hdnRegion = "<%=hdnRegionId.ClientID%>";
var regionIdVal = $("#" + hdnRegion).val();
methodName(regionIdVal);
another one:
var currentControl = "<%=this.ClientID%>";
var hdnRegion = currentControl + "_" + "hdnRegionId";
var regionIdVal = $("#" + hdnRegion).val();
methodName(regionIdVal);
I also tried to call a property from code behind that returns the value and one that returns the whole control with no correct result.
Any suggestions would be appreciated...
Accourding to your comment under the question, your btnUpdate and hdnRegionId controls are in the same container (for instance in the same div) so try this:
$('input[id*="btnUpdate"]').click(function(){
var regionIdVal = $(this).parent().children('input[id*="hdnRegionId"]').val();
methodName(regionIdVal);
});
This is a JSFiddle Demo that simulate your HTML code that is rendered by ASP.NET.
I want to fill a textarea with c# webbrowser , but the textarea is created with "jhtmlarea.js".
This code does not work:
HtmlElement textArea = webBrowser1.Document.All["message"];
if (textArea != null)
{
textArea.InnerText = "This is a test";
}
How do I set the string to javascript editor like "jhtmlarea.js"?
Please help me.
The Webbrowser-control contains a method called "InvokeScript". You can use it to invoke a piece of JavaScript in your document. Simply call
browser.InvokeScript("myFunction", new object[] { arg1, arg2,});
to invoke the function.
See here for further reference.
HtmlElement ele = webBrowser1.Document.GetElementById("message");
if (ele != null)
ele.InnerText = "This is a test";
using GeckoFX web browser, is it possible to pass a GeckoElement through JavaScript like this,
WebBrowser.Navigate("javascript:void("+ele.DomObject+".onclick())");
I'm selecting the DOM element through JavaScript (this works fine) atm, but i have the element in c#.
Unfortunately elements can't be passed to javascript like that.
However, the WebBrowser.Navigate call is unnecessary and causes an unneeded loss of page variables.
For the sake of completeness I've posted a snippet - long winded for this occasion ;) - that injects javascript and then calls it from an automated button click via a button.click() handler without the need to navigate the browser to run it all.
DOM.GeckoScriptElement script = Document.CreateElement("script").AsScriptElement();
script.Type = "text/javascript";
script.Text = "function doAlert(){ alert('My alert - fired by automating a button click on the [Automated Button]'); }";
Document.Body.AppendChild(script);
script = Document.CreateElement("script").AsScriptElement();
script.Type = "text/javascript";
script.Text = "function callDoAlert(id){ var el = document.getElementById(id); el.click(); }";
Document.Body.AppendChild(script);
DOM.GeckoInputElement button = Document.CreateElement("input").AsInputElement();
button.Type = "button";
button.Id = "myButton";
button.Value = "Automated Button";
button.SetAttribute("onclick", "javascript:doAlert();");
Document.Body.AppendChild(button);
DOM.GeckoInputElement button2 = Document.CreateElement("input").AsInputElement();
button2.Type = "button";
button2.Id = "myOtherButton";
button2.Value = "Press Me";
button2.SetAttribute("onclick", "javascript:document.getElementById('myButton').click();");
Document.Body.AppendChild(button2);
//uncomment to fully automate without the <webbrowser>.Navigate("javascript:.."); hack
//button2.click();
I'm not sure this snippet will help you, directly, as it's mainly focused on using the GFXe build of the control but, I'm sure it will point you in a better direction than the
WebBrowser.Navigate("javascript:hack.goesHere()"); trick.
You can do this with the following:
WebBrowser.Navigate("javascript:void(document.getElementById('"+button.Id+"').click())");
i have the name of a control in a string and I want to manipulate the control, how do i turn the string into the current form instance of that control in c#?
e.g.
string controlName = "Button1";
What goes here?
button1.text = "Changed";
Thanks
Button button1 = (Button)this.Controls[controlName];
You need to look up the control in the controls collections, then cast it to the correct type. Is this in WPF , WinForms or ASP.Net?
Inside the form, you could write (c#)
this.Controls["Button1"].Text = "Changed";
I suppose, this could be the syntax in vb.net
Me.Controls("Button1").Text = "Changed"
EDIT: I don't know, if that would compile. #Binary Worrier is right
Button btn1 = this.Controls["Button1"] as Button;
btn1.Text = "Changed";
