Hello, I can configure columns of an UltraWinGrid at design time, but whenever I set the DataSource this configuration will be overwritten even though the DataSource matches the configuration. Lets say I have defined a Band with two colums "customer" and "amount" - a string and an decimal value. At design time I set the CellActivation of column "customer" to NoEdit and the MaskInput of column "amount" to "-nn.nn". The scale of the amount in the DataSource is 28. When I set this DataSource at runtime my configuration will be changed by inference from the DataSource, i.e. the aoumnt is displayed with 28 decimal places and customer is editable. Can I avoid this? I know that this will be a problem, if the DataSource doesn't match the design time schema but I can presume that it does. TIA, Frank
