I think you mean that make sure that what was entered in each column is in the correct format, which you can do with regular expressions. There are a lot of articles about it, try RegexTester.asp[^] to get you started. Hope this helps. :)

well u can handle this situation without using regular expressions as well. You need to handle the cellValidating event of the DGV and in that u'd code somthin like this. int i; if(e.ColumnIndex == myDGVCol1.DisplayIndex) { if(!Int32.TryParse(e.FormattedValue,out i)) { e.Cancel = true; MessageBox.Show("It is not an integer"); // or myDGV[e.ColumnIndex, e.RowIndex].ErrorText ="Whatever"; } // similarly u can use the tryparse methods of DateTime classes etc } and in order to go without taking special charaters u can use string manuipulation but I dont have the sample right now... hope it helps Rocky
