In ultrawebgrid I added validation to a cell.The error message displayed in the cell itself.But I want the error message to be displayed in the validation summary.
A validator's .Text property appears in the validator, and its .ErrorMessage property appears in the summary.
IIRC, you need to set both, or one will default to the other, (I think).
Ultrawebgrid does not work with ValidationSummary, because in the others validation controls, the ControlToValidate property is the name of the grid and the validation scripts can not identify problems in the specifics cell's. Even Text an ErrorMessage properties was configured.
