You can use GetSelectedObject method and Get the specific Cells you need.

e.g

function WebGrid1_OnButtonClick(controlId, tblName, colName, cellValue)
{
	var WebGrid1 = ISGetObject(controlId); 
	var selObj=WebGrid1.GetSelectedObject();
	var rowObj=selObj.ToRowObject();
	var cellObj=rowObj.GetCells();
	alert(cellObj[1].Value);
	return true;
}

 Hope this helps

Handy,

Thanks for your answer, I need to do this on the server, because I'm passing those values to a stored proc.

You can use AddInput method to pass the values on server.
To do this, please set AutoPostback true on WebGridButton and add the following codes:

function WebGrid1_OnButtonClick(controlId, tblName, colName, cellValue)
{
	var WebGrid1 = ISGetObject(controlId); 
	var selObj=WebGrid1.GetSelectedObject();
	var rowObj=selObj.ToRowObject();
	var cellObj=rowObj.GetCells();
	WebGrid1.AddInput("cellValue", cellObj[1].Value);
			
	return true;
}

C#
protected void WebGrid1_InitializePostBack(object sender, ISNet.WebUI.WebGrid.PostbackEventArgs e)
    {
        if (e.Action == "ButtonClick")
        {
            string cellValue = Request.Form["cellValue"].ToString();
            WebGrid1.ClientAction.Alert(cellValue);
        }
    }

 Hope this helps

This would be so much easier if there was a Webgrid.rows.CurrentRow or SelectedRow

Handy can you attach a sample with serverside code.  I also need to be able to launch a dialog window on button click. 

Attachment is my sample which will show the dialog you need. Hope this helps.

Handy,

Thanks for the attachment.  Please recompile it for WebGrid 7 SP1.  When I opened it, it replaced my dlls and I had to repair my installation.  Thanks again!

George,

But i only attached .aspx and .aspx.cs. I never heard that this could affect your installation. In fact, i am also using SP1.
