Public Sub Clear( _ ByVal row As Integer, _ ByVal column As Integer, _ ByVal rowCount As Integer, _ ByVal columnCount As Integer _ ) | |
| Visual Basic (Usage) |  Copy Code |
|---|---|
Dim instance As DefaultSheetDataModel Dim row As Integer Dim column As Integer Dim rowCount As Integer Dim columnCount As Integer instance.Clear(row, column, rowCount, columnCount) | |
Parameters
- row
- Row index of start of range to clear
- column
- Column index of start of range to clear
- rowCount
- Number of rows to clear
- columnCount
- Number of columns to clear
Remarks
As an example, suppose you wanted to clear data for the range of cells from B2 to E4. You would set the column and row parameters to 2, the rowCount parameter to 2, and the columnCount parameter to 3.
Clearing data in the data model clears the data, including the formula, the cell note, and the cell tag. Formatting is not handled by the data model, so calling the Clear method in the data model does not clear formatting, including things such as colors.
To clear just the data, and not the formula, cell note, or cell tag, if present, use the ClearData method.
Example
This example adds data to the first three columns. In the click event of a button the data is cleared from the first two columns.
