Duc Nguyen: ths for ur attention:)

  I use ultrawebgrid in a Contentpage (with masterpage) and use javascript to Delete record from database(MS sqlserver). In the grid ,I add a column which doesn't bind with data ,and i define the Its type --Button. The clientScript-"clickcellbuttonHandler":

function  DeleteRecord()
   {
     if (confirm("Delete current row？")==true)
     {
       var oGrid = igtbl_getGridById("UltraWebGrid1");
       if (oGrid.getActiveRow()!=null)
          {
            var oRow = oGrid.getActiveRow();
            oRow.deleteRow();
            document.getElementById("aspnetForm").submit();
          }
      }
   }

The message tell me :object not defined. and now the function was changed to :

function UltraWebGrid1_ClickCellButtonHandler(gridName, cellId){
  var oCell = igtbl_getCellById(cellId);
     var oRow = oCell.getRow();
  if (oCell.Column.Key=="Edit")
         { 
             document.location = "Mgr_InformationEdit.aspx?id="+oRow.getCellFromKey("ID").getValue();
         }
         else
         if (confirm("Delete current row？")==true)
         {         
             oRow.deleteRow();
             document.getElementById("aspnetForm").submit();            
          }
}.

for the test ,I add an html button in a blankpage just with ultrawebgrid,and onclick:

   function button1-click(){

 var oGrid = igtbl_getGridById("UltraWebGrid1");
       if (oGrid.getActiveRow()!=null)

       alert("good");

}

The same message appear again.

can u help me?

ths a lot!

Since your grid is within a content pane, its html id changes. Therefore, you cannot get reference to the grid with the original id assigned. To get around this, handle the InitiailizeLayout client-side event of WebGrid. In this event handler, set a global variable to hold the gridName parameter passed in. In place of your hard-coded grid id, use the global variable.

Duc Nguyen: Thanks a lot:) 

  You means in the .cs file I difine a public string grdID="mygrid1" then in the aspx file set "id=<%grdID%>"? I will try it immediatly.

Define in your javascript section, wherever you define the delete method.

var gridId;

In the handler,

gridId = gridName;

gridName is a parameter passed into the handler for InitializeLayout. Remember this is the client-side event.

Use gridId wherever you need the id for WebGrid.

Thank u very much! I follow ur instructions,and it worked...........thanks again:)
