Rob,

Try this:

function AddBlankGridRows_Click(oButton, oEvent) //this is called via a web image button click....
{
    var tbAddRows   = document.getElementById("ctl00_cphContent_tbRowCnt"); //get text box...
    var addRowCnt   = tbAddRows.value;  //a text box with the number of rows you want to add...
    var aNum ;
    var grid = igtbl_getGridById("ctl00_cphContent_GRIDNAME");
   
    if (addRowCnt == "")
        {
            grid.Rows.addNew();
        }
        else if (addRowCnt != "")
        {
            for (aNum = 1; aNum <= addRowCnt; aNum++)
            {
                grid.Rows.addNew();
            }
        tbAddRows.value = "";
        }
     }
}

var newRow = GrdBspCompanyRowsCollection.addNew();   ---  Adding a new blank row to the rows collection

newRow.getCellFromKey('CompanyName').setValue(txtCompanyName.value);

newRow.getCellFromKey('BspPlugInID').setValue($get('<%= this.hfBspPluginID.ClientID %>').value);

This works when there are actual rows in the grid.  My problem is if there is an empty grid this will fail.

That is client side code but from what I have tried it does not work.  The method keeps returning my an undefined row.  So I can't add any rows to my grid through the client side.

That code seems to be server side. In the application I am doing, I want to allow the user to enter several lines of data without posting back to the server until they click a submit button. To complicate matters, they would like to be able to enter a number of lines to add and add them all at one time.

I was hoping that someone would have tried this before me and could tell me how to get it accomplished.
