UltraWebGrid.copy() fails

Mark Oudesluys posted over 15 years ago

Hi,

I have been trying to get the copy() function to work for my WebGrid, but it keeps returning false. Here is my javascript code for capturing the context menu:

function ShowContextMenu(evt){

//Firefox passes event arg as parameter (evt). If that is null, we'll use window.event (Internet Explorer proprietary)

var e=evt?evt:window.event;

//Call show menu with menuID

//specify clientX and clientY to get more accurate positioning for this particular layout

igmenu_showMenu("<%=this.muContextMenu.ClientID %>",null,(e.clientX+document.documentElement.scrollLeft)+"px",(e.clientY+document.documentElement.scrollTop)+"px");

//Firefox (W3C) - cancel event

if(typeof(e.preventDefault)=="function")e.preventDefault();

//InternetExplorer (Proprietary) - cancel event

e.returnValue=false;

return false;

}

function ContextMenuItemClick(menuid,itemid)

{

//Grab a reference to the ContextMenuItem that was clicked on

var item=igmenu_getItemById(itemid);

var oGrid = igtbl_getGridById("ugContacts");

var nRows = oGrid.Rows.length;

if(item!=null){

//We'll use the text from the menuitem to decide which operation to perform

switch(item.getText()){case "Select All":

oGrid.selectRowRegion(oGrid.Rows.getRow(0), oGrid.Rows.getRow(nRows-1));

break;

case "Copy":

oGrid.copy();

break;

case "Export To Excel":

document.getElementById("wibExport2Excel").click();break;

}

function ugContacts_MouseUpHandler(gridName, id, button)

{

if(button!=2){

//Because the WebGrid consumes all mouse events, we need to add

//a listener to determine when a mouse click has occured so we can

//close the popup menu appropriately

igmenu_getMenuById("<%= this.muContextMenu.ClientID %>").dismiss();

}

The "Select All" and "Export to Excel" functions properly, but the copy returns a false when I capture it's return value.

I have a WebGrid in a page, it is hierarchical, and I have CellClickActionDefault set to RowSelect. Here is my UltraWebGrid setup:

<igtbl:UltraWebGrid ID="ugContacts" runat="server" Height="560px" Width="100%"

oninitializelayout="ugContacts_InitializeLayout"

OnDataBinding="ugContacts_DataBinding">

<Bands>

<igtbl:UltraGridBand>

</rowstyledefault>

</SelectedRowStyleDefault>

</GroupByBox>

<boxstyle backcolor="LightGray" borderstyle="Solid" borderwidth="1px"

Font-Names="Microsoft Sans Serif" Font-Size="XX-Small">

<borderdetails colorleft="White" colortop="White" widthleft="1px"

widthtop="1px" />

</boxstyle>

</addnewbox>

<activationobject bordercolor="" borderwidth="0px" allowactivation="False"

borderstyle="None">

</activationobject>

</AddNewRowDefault>

</displaylayout>

</igtbl:UltraWebGrid>

Am I missing something? Do I have a setting improperly set? Or is this not possible with hierarchical grids?

I appreciate any assistance.

Try setting your CellClickActionDefault in display layout properties of your grid to select a cell and then add row selectors to your grid to select rows. See if this setting helps zero in on the cell and copy the cell correctly. Note that I have not got the copy functionality working in FF.

I think, especially for FireFox, clipboard operations are not something that the UltraWebGrid can control internally. FireFox is very strict when it comes to permissions and especially clipboard operations.
Still, there are some venues you can try. I think the following thread is especially useful:

http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_21269346.html
[scroll down a lot after the Ads to see the response]
and especially the generic copy function here:
function copy_clip(maintext)
{

if (window.clipboardData)
   {

   // the IE-manier
   window.clipboardData.setData("Text", maintext);

   }
   else if (window.netscape)
   {

   netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');


   var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
   if (!clip) return;


   var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
   if (!trans) return;


   trans.addDataFlavor('text/unicode');


   var str = new Object();
   var len = new Object();

   var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);

   var copytext=maintext;

   str.data=copytext;

   trans.setTransferData("text/unicode",str,copytext.length*2);

   var clipid=Components.interfaces.nsIClipboard;

   if (!clip) return false;

   clip.setData(trans,null,clipid.kGlobalClipboard);

   }
   alert("Following info was copied to your clipboard:\n\n" + maintext);
   return false;
}

I appreciate the suggestion above, with all the code, but this seams like a cludge instead of a solution. I think the real solution is for Infragistics to fix thier application so the copy function works.

I will open a trouble ticket with them to get this issue fixed.

Right, this is a good way to go. While we do try the best to help here (in peer to peer forums), sometimes it is better (especially in urgent cases) to contact our official dedicated support services, especially for tricky questions like security / clipobaord operations in various browsers.
Hopefully someone else will also be able to add something here (if he got that working correctly in this case)

Hi,

So I finally figured out what I had set incorrectly, in order to make the copy() function work. Below is what I originally had set:

<activationobject bordercolor="" borderwidth="0px" allowactivation="False" borderstyle="None"></activationobject>

Now, all I needed to do was remove the allowactivation="False" tag, and it is good to go:

<activationobject bordercolor="" borderwidth="0px" borderstyle="None"></activationobject>

Why Infragistics couldn't just tell me this is beyond my ability to understand. I had to figure this out from a working example they sent me and change sections one at a time in the WebGrid module until I found the setting that caused the copy() to fail.

I hope this helps others who have had the same issue.
