is there an event proceding the DragDrop Event

hello , sadly im a noob , and i cant manage to find an event that would accure after i droped a file in a richtextbox

*when u drop a file into a Rtb the icon's image is copied on to the control if u i downloaded a userr control wich derives from richtextbox , this control as a few method in wich it manipulates RTF among does are AppendRtf(_rtf)

now i want to present u with a secnario wich works

1) i drag a file into the Rtb, i check if its a file deing draged onto the control if true i render all effects

void txt_send_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)

{

txt_send.Clear();

if (e.Data.GetDataPresent(DataFormats.FileDrop, false) == true)

{

e.Effect = DragDropEffects.All;

}

2) i drop the file ,here for this secnario all i do is update a boolean value that indicates the file as been droped

void txt_send_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)

{

File_droped = true;

}

*after this event (2) an image is inserted into the Rtb

3) FINALLY in order to test the issue i presented above , i call the mouseUp event , wich there i copy that image's RTF(Rich Text Format)

*so now ill click the control , and the following event is dispatched

*I JUST WANT TO CLARIFY THAT IM AWARE THE MOUSEUP DOSE NOT ACCURE AFTER THE DRAGDROP EVENT ,I ONLY ADD IT TO TEST THE ACCTUALL OPERATION I WANT TO PREFORM AND SEE THAT IT WORKS,

void txt_send_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)

{

if (File_droped)

{

txt_main.AppendRtf(txt_send.Rtf);

}

*now the file's icon (Image) is copied to anouther RichTextBox (THIS WORKS)

now again what im looking for is an acctuall event that accures after the DragDrop Event , becuase i want this to preform after DragDrop as ended

if i attempt to do this from inside the event ,it wont work becuase the image only appears after the event

txt_main.AppendRtf(txt_send.Rtf);

i dont see how , i was just looking for an event that procedes the DragDrop event , like if a mouse had a mouse down event it as a mouse up event, but what comes after DragDrop, im looking for somthing like "Droped" (i.e. after DragDrop)

You can use Spy++ to see what messages are sent to a control; do you know how to use it?

It is possible to handle all messages for a window in a .Net event and filter for the ones you do or don't want to see. Would that help?
