C# Switch-case Loop for Datagridview cells
- by Nail Yener
Hi,
I am working on a form with datagridview and webbrowser controls. I have three columns as URL, username and password in datagridview. What I want to do is to automate the login for some websites that I use frequently. For that reason I am not sure if this is the right approach but I created the below code. The problem is with the argument of switch.
I will click the row on datagridview and then click the login_button so that the username and password info will be passed to the related fields on the webpage. Why I need a switch-case loop is because all the webpages have different element IDs for username and password fields.
As I said, I am not sure if datagridview allows switch-case, I searched the net but couldn't find any samples.
private void login_button_Click(object sender, EventArgs e)
{
switch (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString())
{
case "http://www.website1.com":
webBrowser1.Document.GetElementById("username").InnerText = dataGridView1.Rows[3].Cells[3].Value.ToString();
webBrowser1.Document.GetElementById("password").InnerText = dataGridView1.Rows[3].Cells[4].Value.ToString();
return;
case "http://www.website2.com":
webBrowser1.Document.GetElementById("uname").InnerText = dataGridView1.Rows[4].Cells[3].Value.ToString();
webBrowser1.Document.GetElementById("pswd").InnerText = dataGridView1.Rows[4].Cells[4].Value.ToString();
return;
}
HtmlElementCollection elements = this.webBrowser1.Document.GetElementsByTagName("Form");
foreach (HtmlElement currentElement in elements)
{
currentElement.InvokeMember("Login");
}
}
