Hey folks having issues finding any info on how I might remap the left click event in C# to be a right click event.
For example, everytime the user left clicks on a DataGrid in my application I want to be able to capture the left click and map it to a right click. So how do I simulate a right click every time the left click on the mouse is used. I've found some old .net2.0 examples where some C++ was ported over to C# to allow simulating clicks but I don't think it would be suitable and I don't truly understand what it was doing.
Any help appreciated. Thanks!
Just handle the mouse click event of the Datagrid
private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
contextMenuStrip1.Show();
}
else if (e.Button == MouseButtons.Right)
{
//What you want it to do
}
}
When handling the event, check if it is a right click or a left one. No need to map the mouse clicks.

I'm in Visual Studio using c#. I have a label element that I'm trying to get to act as a toolbox. I added
contextMenuStrip1.Show();
to the mousedown event, so that my context menu pops with all the tools on it. It shows up in the very top left of the screen though. As a note, that's the default position, but if I do right click it into existence, left click then just gives it in the last place it was set from right clicking. I basically just want the left click to give the same behavior of the right click, and have no clue of what parameters to set to cause that to happen.
Try using the parameters that pass the control and the mouse location:
void label1_MouseDown(object sender, MouseEventArgs e) {
if (e.Button == MouseButtons.Left) {
contextMenuStrip1.Show(label1, e.Location);
}
}
I have a right click menu on c# winforms and the question is when I right click to get the menu how do I not get it to select the item when I right click?
I found a similar question, but it is for WPF here at this link
The problem being that i have index_changed event that is affected by the right click and i don't want it to be.
I am guessing that you want this to be handled in the Listviews selected index changed event..... The sample below shows how to determine the button pressed. Al it does is tell you yes or no if the right mouse button was clicked. This is the simplest example I can show without knowing your code.
private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
MessageBox.Show(Form.MouseButtons.HasFlag(MouseButtons.Right).ToString());
}
I want a ListView to behave like this:
With mouse Input:
Left Click -> Item click event handler gets executed, but should not
display it as "selected"
Right Click -> Item gets selected
With touch Input:
Single Tap -> equivalent to left click
Swipe Down -> equivalent to right click
I have played around with various of the events and settings but cant seem to get it to work right.
In other words, you want your listview to behave like the Windows Start screen? This one was brutal for me to figure out - the mouse part was easy, but the touch part not so much. The solution turns out to be pretty easy. You just have to enable the right options for your listview. Here's the xaml for mine:
<ListView
x:Name="itemListView"
SelectionMode="Extended"
IsSwipeEnabled="True"
IsItemClickEnabled="True"
ItemClick="ItemView_ItemClick"
/>
Sorry, I haven't figured how to get code to highlight in StackOverflow yet.
This could help you with the mouseclicks
private void MainForm_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
method()
if (e.Button == MouseButtons.Right)
set selection = false
method()
}
and for the handle of the touch i hope this helps

How do I handle right click in RichTextBox in C#?
For example:
When I right-click mouse over a RichTextBox the program will display a MessageBox.
You have to catch Mouse_Down event, not Mouse_Click as follows:
private void richTextBox1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Right)
{
MessageBox.Show("you got it!");
}
}
Subscribe to the MouseClick event and check the MouseEventArgs.Button property to see which button was clicked.
What have you tried for yourself?
click RichTextBox in design mode .Right click and select properties and Then navigate to MouseDown Event.Double click that event and you will be directed to Code behind page and there you can write your code.
I have a control that creates a popup menu on right click, and I need the best way to close it on left click. Besides handling the mouseDown event of everycontrol in my application, what is the best way to close the popup menu?
Like a global mouse click event....
private void lbKeywords_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
listBoxMenu.ShowPopup(Cursor.Position);
}
}
As an answer: try asking DevExpress or looking at their support pages - i.e. I found this after a quick search: devexpress.com/Support/Center/p/CQ14210.aspx
