Hi,
EO.Web Grid rows are always populated from a data source. So you would not control the number of rows for the Grid directly. Instead you would control the number of items in your data source. If you do not care about any data source. You can simply do something like this:
Code: C#
Grid1.DataSource = new object[3];
Grid1.DataBind();
This will create 3 empty rows because the data source is an array with 3 elements.
Hope this helps.
Thanks!
