Hi,

I am trying Ext.Net controls.
I am having some problem with drag-drop within gridpanels.Certainly I am missing something but after 2 hours of scratching my head,I am still not able to find my mistake.
I am able to see the records in Gridpanel1 and can drag the record,but after I drop it in Gridpanel2 it disappear,it is still in gridpanel1.
I am really lost.



<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

<script type="text/javascript">
// Generic function to add records.
var addRow = function (store, record, ddSource) {
debugger;
// Search for duplicates
var foundItem = store.findExact('ProductName', record.data.ProductName);

// if not found
if (foundItem == -1) {
//Remove Record from the source
ddSource.grid.store.remove(record);

store.add(record);

// Call a sort dynamically
store.sort('ProductName', 'ASC');
}
};

var notifyDrop1 = function (ddSource, e, data) {
// Loop through the selections
debugger;
Ext.each(ddSource.dragData.selections, function (record) {
addRow(Store1, record, ddSource);
});

return true;
};

var notifyDrop2 = function (ddSource, e, data) {
// Loop through the selections
debugger;
Ext.each(ddSource.dragData.selections, function (record) {
addRow(Store2, record, ddSource);
});

return true;
};
</script>
