C# – Capture the mouse right click event of a web browser control

cwebbrowser-controlwinforms

I would like to select all when a user right clicks on my web browser control.

I am developing a win forms app, and use web browsers to display my information, because i can use html to style the words.

The right click context menu is not working for me. The options on it are all irrelevant to my app.

But the context menu after a select has been made i want to keep, the copy, cut, paste options.

I can already select all:

getCurrentBrowser().Document.ExecCommand("SelectAll", true, null);

I would just like to do it in the right click event of the web browser?

Handle MouseDown event:

webBrowser.Document.MouseDown += new HtmlElementEventHandler(Document_MouseDown);

and make sure user pressed Right button, then select all:

void Document_MouseDown(object sender, HtmlElementEventArgs e)
{
    if(e.MouseButtonsPressed == MouseButtons.Right)
    {
        webBrowser.Document.ExecCommand("SelectAll", true, null);
    }
}

C# – Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on

As per Prerak K's update comment (since deleted):

I guess I have not presented the question properly.

Situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread.

So only accessing the value so that corresponding data can be fetched from the database.

The solution you want then should look like:

UserContrl1_LOadDataMethod()
{
    string name = "";
    if(textbox1.InvokeRequired)
    {
        textbox1.Invoke(new MethodInvoker(delegate { name = textbox1.text; }));
    }
    if(name == "MyName")
    {
        // do whatever
    }
}

Do your serious processing in the separate thread before you attempt to switch back to the control's thread. For example:

UserContrl1_LOadDataMethod()
{
    if(textbox1.text=="MyName") //<<======Now it wont give exception**
    {
        //Load data correspondin to "MyName"
        //Populate a globale variable List<string> which will be
        //bound to grid at some later stage
        if(InvokeRequired)
        {
            // after we've done all the processing, 
            this.Invoke(new MethodInvoker(delegate {
                // load the control with the appropriate data
            }));
            return;
        }
    }
}

C# – right click context menu for datagridview

You can use the CellMouseEnter and CellMouseLeave to track the row number that the mouse is currently hovering over.

Then use a ContextMenu object to display you popup menu, customised for the current row.

Here's a quick and dirty example of what I mean...

private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        ContextMenu m = new ContextMenu();
        m.MenuItems.Add(new MenuItem("Cut"));
        m.MenuItems.Add(new MenuItem("Copy"));
        m.MenuItems.Add(new MenuItem("Paste"));

        int currentMouseOverRow = dataGridView1.HitTest(e.X,e.Y).RowIndex;

        if (currentMouseOverRow >= 0)
        {
            m.MenuItems.Add(new MenuItem(string.Format("Do something to row {0}", currentMouseOverRow.ToString())));
        }

        m.Show(dataGridView1, new Point(e.X, e.Y));

    }
}
