I am using NetAdvantage for .NET 2008 Vol. 1 CLR 2.0. I am getting an javascript error occationally when a edit operation is done in the UltraWebGrid.

I get the following error

"Object doesn't support this property or method"

in the source.axd file in the line editor.setValue(v,false); where the editor has a value elemID -1.

Below is the function name and code where I get the error. I have indicated the error line in bold.

function igtbl_editCust(g,v,r,col,cElem)
{
    var id=col.EditorControlID,editor=col.getEditorControl();
    if(editor==null && id!=null)
    {
        if((editor=igtbl_getElementById(id))!=null)
            editor=editor.Object;
    }
    if(editor==null)
        return null;
    col.editorControl=editor;
    var elem=editor.Element;
    g._ensureValidParent(editor);
    editor.setValue(v,false);
    elem.style.zIndex=r.z;
    if (elem.tagName=="INPUT")
    {
       
        if(g.IsXHTML)
        {
           
            if (ig_csom.IsIE)
            {

                r.y-=2;
            }

            }
        }
       
    }
    else if(ig_csom.IsIE && g.IsXHTML)

        r.x--;
        r.y--;
    }

I am setting the editor control id and type as below in the code behind Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

EditorControlID = WebNumericEdit2.ID;

.Type = ColumnType.Custom;

 I have an update cell event which updates the values of the grid based on the newly entered value. When a user enters a new value and scrolls or clicks on other cells the editor text box does not scroll with the grid and gives a floating kind of a feel. Now when the user clicks on other cells we get the JavaScript error.

This error occurs occasionally and when I do multiple operations.

Kindly let me know what is cause and how I can fix this error.

Regards,

Vikram
