I need to get the value of a textbox in each row that I loop through in a radgrid using javascript.  Here is the code to grab the cell which works fine.

var masterTable = $find("<%=gvLines.ClientID%>").get_masterTableView();
var cell;

for (var row = 0; row < masterTable.get_dataItems().length; row++)
{
     cell = masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[row], "Amount").innerHTML;
     alert(cell);
}  

The alert box value is:  <INPUT id="textboxid" class="textbox" value="$52.8: type="text" name="Amount">

How can I grab the value $52.8?

Thanks.

I'm getting the "Microsoft JScript runtime error: Object doesn't support this property or method" error.

-- oh sorry - can you try this

 var masterTable = $find("<%=gvLines.ClientID%>").get_masterTableView();
 var cell;
 for (var row = 0; row < masterTable.get_dataItems().length; row++) {

       // get the cell with the textbox
       cell = masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[row], "Amount");          

      // now get the value by tag name
       alert(cell.getElementsByTagName("input")[0].value);  


 }
