Enabling HTTP Handler to render in IE Compatibility mode

HTTP handlers are generally used for download a file, show an image, or even to show a report (ie.. generated as html at runtime and stream it through)

Now consider your html report was generated and now all you need to do is show through your website using ASP.NET http handler. Opening the report html just show all the formatting properly but via http handler some of styles were not correctly applied.

To resolve this you have got 2 options
- Modify your CSS to render it properly
- Force your handler to render in compatibility mode

In order to force your handler to render in compatibility mode all you need is to just add a header

for eg you can force usage of IE8

Response.AddHeader("X-UA-Compatible", "IE=EmulateIE8");

or use microsoft standard. Refer to microsoft article "Specifying legacy document modes"

Response.AddHeader("X-UA-Compatible", "IE=edge");

Using Selenium WebDriver to simulate button click for ASP.NET Webforms application that uses DevExpress Controls

First lets create a simple ASP.NET Web application that uses DevExpress controls. I have created a test.aspx page that has got 2 buttons

Code behind (test.aspx.cs)

protected void TestMe_Click(object sender, EventArgs e)
{
  Response.Redirect("success.aspx");
}

protected void TestMe2_Click(object sender, EventArgs e)
{
  Response.Redirect("Fail.aspx");
}

Now here is the snippet of code that can be used to simulate button click

WebDriver driver = new InternetExplorerDriver(@"C:\selenium\selenium-dotnet-2.33.0\IEDriverServer_x64_2.33.0");
driver.Navigate().GoToUrl("http://localhost/test/Test.aspx");
IJavaScriptExecutor js = driver as IJavaScriptExecutor;
var result = js.ExecuteScript("TestMe.click();");
//or
IWebElement btn = driver.FindElement(By.Id("TestMe"));
btn.Click();
