Argument |
Description |
|---|---|
dwcontrol |
The name of the Web DataWindow control in which you want to set a specific row and column to a value. |
row |
The row location of the data. |
column |
The column location of the data. Column can be a column number or a column name. |
value |
The value to which you want to set the data at the row and column location. |
Although JavaScript does not distinguish between the Date, DateTime, and Time datatypes, the DataStore will give an error if the wrong type is passed. You can use the SetItemDate and SetItemTime methods to set values in columns with the Date and Time datatypes.
Because the Web DataWindow server component does not support overloading, you must use the SetItemDateTimeByColNum variant instead of the standard SetItemDateTime method when you want to refer to the column by number.
