ItemTemplate problem

Question

Hi What it should do: I want put a button in every empty cell in the datagrid and when that button is clicked it puts a time stamp in the database in that specific cell of data. Thus when the datagrid is updated that cell will now have a timestamp instead of a button. What it does now: When I check if the cell is empty "if (e.Item.Cells[4].Text =="")", even if the cell has data in it it still puts a button in it. So the end result is that the cell has both a timestamp and a button. When I add the following butReceive.Attributes("onclick") = "javascript:TimeStamp()"; Compiler Error Message: CS0118: 'System.Web.UI.WebControls.WebControl.Attributes' denotes a 'property' where a 'method' was expected. When I click the button I want it to go to the function TimeStamp. Once it goes to the TimeStamp function I need to know the name of the column the cell was in and also the "pas_no" this is a unique id of the row so I can add the timestamp to the database. Please can you help <%# DataBinder.Eval(Container.DataItem, "ts_received") %> <%# DataBinder.Eval(Container.DataItem, "ts_profess_check") %> <%# DataBinder.Eval(Container.DataItem, "ts_label_dispense") %> <%# DataBinder.Eval(Container.DataItem, "ts_awaiting_check") %> <%# DataBinder.Eval(Container.DataItem, "ts_completed") %> <%# DataBinder.Eval(Container.DataItem, "ts_query") %> void UpdateImage(Object sender, DataGridItemEventArgs e) { if((e.Item.ItemType != ListItemType.Header)) { Button butReceive = new Button(); butReceive.Text="Update"; butReceive.Attributes("onclick") = "javascript:TimeStamp()"; Button butPCheck = new Button(); butPCheck.Text="Update"; Button butDispense = new Button(); butDispense.Text="Update"; Button butACheck = new Button(); butACheck.Text="Update"; Button butComplete = new Button(); butComplete.Text="Update"; Button butQuery = new Button(); butQuery.Text="Update"; //but.Attributes("onclick") = "UpdateImage"; if (e.Item.Cells[4].Text =="") { e.Item.Cells[4].Controls.Add(butReceive); } if (e.Item.Cells[5].Text =="") { e.Item.Cells[5].Controls.Add(butPCheck); } if (e.Item.Cells[6].Text =="") { e.Item.Cells[6].Controls.Add(butDispense); } if (e.Item.Cells[7].Text =="") { e.Item.Cells[7].Controls.Add(butACheck); } if (e.Item.Cells[8].Text =="") { e.Item.Cells[8].Controls.Add(butComplete); } if (e.Item.Cells[9].Text =="") { e.Item.Cells[9].Controls.Add(butQuery); } } void TimeStamp(Object sender, DataGridItemEventArgs e) { //Add a timestamp to that cell in the database }
