Sheet Resizing
As of the R1 2022 SP2 release, the Spreadsheet Sheet exposes a resize method that allows you to change the number of the rows and columns in the current sheet.
The new functionality increases or decreases the size of the rows and columns after loading. The sheet automatically resizes after the user pastes more data than the current sheet size allows for and exposes flexible behavior when the user adds or deletes columns and rows from the toolbar.
If you delete rows or columns within a sheet, the sheet may lose data. If a row or column is deleted either by using the
resizemethod or by using the Delete Row or Delete Column tool, it will be removed even if it contains data.
Using the resize Method
If the count of the rows or columns is programmatically set through the resize method, the user cannot revert the applied changes through the Undo or Redo toolbar options. In this case, Undo and Redo will take effect only if the user changes the number of the rows or columns with the Insert New Row or Insert New Column, or with Delete Row or Delete Column options.
The example below demonstrates how to set the count of the rows and columns in the current active sheet by using the resize method.
<div id="spreadsheet"></div>
<script>
$("#spreadsheet").kendoSpreadsheet({
sheets: [{
rows: [{
cells: [{
value: "My Company"
}]
}],
},{
name: "Second Sheet"
}]
});
var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");
var sheet = spreadsheet.activeSheet();
sheet.resize(25, 5); //there will be 25 rows and 5 columns in the sheet
</script>
New vs. Old Behavior
The implementation of the resize method changes aspects of the Spreadsheet behavior in the following way:
-
Insert New Row and Insert New Column options—The new functionality allows the user to insert a new row or column in the current sheet, and to increase the number of the initially configured rows or columns. This is possible even if the last row or column in the sheet contains data.
For versions prior to R1 2022 SP2, if the user inserted rows or columns, the data in the sheet would be shifted, but the number of rows or columns would remain the same. The user was not allowed to insert a new row or column in the sheet if the last row or column contained data because of possible data loss.
-
Delete Row and Delete Column options—Now the user can delete rows or columns by right-clicking the row or column and showing the context menu. Also, the user can decrease the rows or columns in the currently active sheet by using the Delete Row or Delete Column options.
For versions prior to R1 2022 SP2, the cells were deleted but the sheet size remained the same.
-
Resizing on pasting data—Currently, when the user pastes more data than the current sheet size allows for, the sheet will automatically add new rows or columns.
Versions prior to R1 2022 SP2 do not support such behavior. In similar cases, the Spreadsheet displayed a dialog with the "Cannot paste, because the copy area and the paste area are not the same size and shape." message.
