Question

In my SQL Server table, if the column value(integer) is nothing it’s inserting value is -1. If i select all column values from table and showing on ASP.net grid it is showing -1 on specified column. I don’t want to show it as -1 it need show like some thing like “null or none”. How can get this?

Answer 1

1 You can insert null in your DataBase. (In your datas you use Type Nullable in order to match )

2 You can also treat your information in your Gridview, by deleting -1 and replacing with null value.

 void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {

    if(e.Row.RowType == DataControlRowType.DataRow)
    {

      e.Row.Cells[1].Text = (e.Row.Cells[1].Text == "-1" ) ? "" :  e.Row.Cells[1].Text;

    }

  }
