So, I found a solution.
I create a new function like this :
public void javascriptSendKeys(String id, String value)
{
String script = "document.getElementById(\"" + id + "\").value=\"" + value + "\" ";
((IJavaScriptExecutor)driver).ExecuteScript(script);
}
And I use it when I need to use a SendKeys method.
It's work fine for me.
Have a nice day !
