How to avoid dragging a form
-
Hi everybody! I'm new on C# programming. I have a main form in my Windows applications that contains other form as a Explorer of folders. I don't want to allow to drag the Explorer form (FrmExplorer). FrmExplorer has a TreeView. I have been looking for information about it and have written the following code: public partial class FrmExplorer : Form { public FrmExplorer(string fileName) { InitializeComponent(); //To cancel dragging the form this.QueryContinueDrag += new System.Windows.Forms.QueryContinueDragEventHandler(this.FrmExplorer_CancelDrag); this.DragEnter += new System.Windows.Forms.DragEventHandler(this.FrmExplorer_EnterDrag); this.DragOver += new System.Windows.Forms.DragEventHandler(FrmExplorer_DragOver); this.AllowDrop = false; } private void FrmExplorer_CancelDrag(object sender, QueryContinueDragEventArgs e) { e.Action = DragAction.Cancel; } private void FrmExplorer_EnterDrag(object sender, System.Windows.Forms.DragEventArgs e) { e.Effect = DragDropEffects.None; } private void FrmExplorer_DragOver(object sender, System.Windows.Forms.DragEventArgs e) { // Determine whether string data exists in the drop data. If not, then // the drop effect reflects that the drop cannot occur. if (!e.Data.GetDataPresent(typeof(System.String))) { e.Effect = DragDropEffects.None; return; } } } I have set the method FrmExplorer_CancelDrag in FrmExplorer Properties in the event QueryContinueDrag. But I still cannot reach the method FrmExplorer_CancelDrag when dragging the form to cancel that action. Does anybody can help me to know what I'm doing wrong or what is it missing? Thanks a lot in advance, Elvia
