Hello,
You can use OnRowValidate client-side event to trigger the validation before you perform adding new row.
You can try to use the following logic. This code is used to validate an empty cell. You can change the logic in order to validate the data type instead.
function WebGrid1_OnRowValidate(rowObject) { // retrieves WebGrid's object var grid = ISGetObject("WebGrid1"); // access WebGrid's RootTable var rootTable = grid.RootTable; var row = rootTable.ToRowObject(rowObject); // convert the rowObject (HTMLElement) to WebGridRow object var cells = row.GetCells(); // get collection of WebGridCell // check for empty cell for (var i = 0; i < cells.length; i++) { var cell = cells[i]; if (cell.Text == "") { var info = "Cell [" + cell.Name + "] value is empty"; alert(info); } } return false; }
Hope this helps. Thank you.
