selecting, using the RIGHT mouse button ?

Question

0.00/5 (No votes)

See more:

I have a listBox1 and a contextMenuStrip1 with a "delete" button.
I made it functional until now, but I must Left click an Item from listBox1 (to select it), then (anywhere) i click right and choose "delete"- it works but not as I really want.

How do I select an Item (from listBox1), using the RIGHT mouse button(to delete that selection only)?

//I use this event to get the mouse buttons:
private void listBox1_MouseDown(object sender, MouseEventArgs e)
        {
            if (listBox1.Items.Count > 0)//if List is NOT empty
            {
                if (e.Button == MouseButtons.Right){
//..?..

Thanks.

Solution 1

You can find selected item then if it's selected delete it.Write these codes to

C#

if (e.Button == MouseButtons.Right){

Like :

C#

for (int i = 0; i < listBox1.Items.Count; i++)
{
    listBox1.SelectedIndex = i;
    Delete(listBox1.Items[i]); // Your delete Code.
}

Reformulate please!
How do I obtain a selection, by clicking with the RIGHT mouse btn inside that listbox?
After the clickEvent is triggered, Ill do the rest of the job (delete,add,etc).
Right now, i cant figure out, how to see the item selected.
I hope the question is more clear now.

It must have some connection with the "MousePosition" and the "listBox1.GetItemRectangle"

SercanOzdemir 4-Nov-11 18:26pm

No you can get selected item with a prepared method.

Iam reformulating it for you Use This On Mouse Click Event of ListBox
:

C#

if (listBox1.Items.Count >; 0)//if List is NOT empty
            {if (e.Button == MouseButtons.Right){

for (int i = 0; i < listBox1.Items.Count; i++)
            {
                listBox1.SelectedIndex = i;
                //Your Delete CODE!
}
} // Your delete Code.            }

NO,Is not working!
I am afraid that you don't understand the question.
HERE:
This is all the code:
<pre>private void listBox1_MouseDown(object sender, MouseEventArgs e)
{
if (listBox1.Items.Count > 0)//if List is NOT empty
{
if (e.Button == MouseButtons.Right)
{
deleteSelectedIndex = listBox1.SelectedIndex;
//Rectangle r = new Rectangle();
//r = listBox1.GetItemRectangle(0);

listBox1.SetSelected(deleteSelectedIndex, true);
contextMenuStrip1.Show(MousePosition); //select at mousePosision =?????????????????????????????
}
}
}</pre>

if you choose listbox1 Contextmenu property to your Contextmenu then it will show it on selection mouse position

_Q12_ 4-Nov-11 19:01pm

No, it does not.
The contextmenu appear on mouse position, but the item from the list does NOT set selected. How can I select it?

_Q12_ 4-Nov-11 19:03pm

Here is a test:
private void listBox1_MouseMove(object sender, MouseEventArgs e)
{
if (listBox1.GetItemRectangle(1).Contains(e.Location))
{
listBox1.SetSelected(1, true);//int index
}
}

BUT:
is selecting ONLY the [1] item from the list.
You see the problem now?
