Disable Mouse Click Event

[selvakumari]

Hi,

i am new to C#,

i have a multiselection treeview, where if i select a nodes with ctrl and shift corresponding nodes will be copied to another treenode,

i want to unselect the childnode selection with ctrl and shift if parent node is selected.

i think of disablin the mouse click event inside that treenode if parent node is selected?

private void treeViewMS1_AfterSelect(object sender, TreeViewEventArgs e)
{
    MyKeyEvent kEv = new MyKeyEvent();
    bool kControl2 = (ModifierKeys == Keys.Control);
    bool kShift2 = (ModifierKeys == Keys.Shift);
    bool mClick = (MouseButtons == MouseButtons.Left);
    // bool parent =IsP
    if (e.Node.Text == "WeldDataFile")
    {
        if ((kControl2) && (mClick))
        {
            // OnKeyAction(this, kEv); 
            //Here i have to disable mouse event till i copy that selected node to another treeview
        }
        else if ((kShift2) && (mClick))
        {
            //OnKeyAction(this, kEv);
            //Here i have to disable mouse event till i copy that selected node to another treeview
        }
    }
}

The easy way is to have a class-level variable that is set to true while you copy the node. Then you just check that variable in other events. The fancy way is to filter out the mouse messages before they reach the controls. If you google for IMessageFilter and mouse, you will find code examples. HTH --Sam
