Anyone know how to do drag and drop?

trueneutral · Dec 18, 2003

I've heard that it's possible to drag text from one textbox and drop it into another textbox. I've looked for examples on this, and I haven't found anything yet that is helpful. Does anyone know either how to do this, or know of any good examples they could point me to?

true: Here's an example from Visual Studio.NET Help in which a text is dragged and dropped into a textbox but from an image to a textbox. You might try and adapt this to two texboxes. Haven't seen a text to text transfer.

Sample

The following example shows the basic code for programming a drag-and-drop operation. This code represents the foundation of a shopping-cart application in which the user drags the icon to the order form and receives textual feedback about the item.

Hide Example

<HEAD>
<SCRIPT>

/* ----------------------------------------------
fnSetInfo sets the data format in the first
parameter and provides the text to drop in second.
The second line copies text.
----------------------------------------------*/

function fnSetInfo() {
event.dataTransfer.setData("Text", "Microsoft Golf 1998&quot

;
event.dataTransfer.effectAllowed = "copy";
}

/* ----------------------------------------------
fnGetInfo is called by the target
object in the ondrop event.
It cancels the default action and
sets the cursor to the system copy icon.
Then it specifies the data format to retrieve.
Last, it sets the value property of oTarget
object to the information from getData.
----------------------------------------------*/

function fnGetInfo() {
event.returnValue = false;
event.dataTransfer.dropEffect = "copy";
oTarget.value = event.dataTransfer.getData("Text&quot

;
}

/* ----------------------------------------------
fnCancelDefault
Cancels the default action in ondragenter
and ondragover so that the copy cursor is
displayed until the selection is dropped.
----------------------------------------------*/

function fnCancelDefault() {
event.returnValue = false;
event.dataTransfer.dropEffect = "copy";
}

</SCRIPT>
</HEAD>
<BODY>
<IMG ID=oSource SRC="Golf98.gif" ondragstart="fnSetInfo()">
<P>Drag the image and drop it onto the text box below. Text data will be pasted into the text box.</P>
<INPUT ID=oTarget VALUE="[drop text here]"
ondragenter="fnCancelDefault()"
ondrop="fnGetInfo()"
ondragover="fnCancelDefault()">
</BODY>
