//--------------------------------------------------------------------------------// 功能:返回表字段在 DBGrid 列中的序号,首序号为0// 参数: pDbGrid:TDbGrid; DBGrid// pcFieldName : string 数据表字段名,字段名不区分大小写// 返回:当表字段在 DBGrid 中存在时,返回表字段所在的列的序号,首序号为0// 否则,返回 -1//例子:DbGrid1.SelectedIndex := GetDbGridColumnIndex( DbGrid1, ''''Price'''' ); //--------------------------------------------------------------------------------Function GetDbGridColumnIndex( pDbGrid:TDbGrid; pcFieldName : string ):integer;var nFldLoop : integer ; cFldName : string ;begin Result := -1 ; For nFldLoop := 0 to pDbGrid.Columns.Count-1 do begin cFldName := pDbGrid.Columns[nFldLoop].FieldName ; If uppercase(pcFieldName) = uppercase( cFldName ) then begin Result := nFldLoop ; exit ; end; end;end;
例子:
DbGrid1.SelectedIndex := GetDbGridColumnIndex( DbGrid1, ''''Price'''' ); 将DbGrid1的当前列定位到字段Price上。
