Hi LanMo, For a DateTimePickerAdv, you need to bind to the BindableValue property. Please see the below given code snippet : ptmpDateTimePicker.DataBindings.Add(new System.Windows.Forms.Binding("BindableValue", mGridDataSet.Tables[mFormParam.TableName],ColumnName); Also please take a look at the following KB Article. How can you setup databinding to your DateTimePickerAdv ? Best Regards, Anu.
