//--------------------------------------------------------------------------------
// 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,
W{ifT03垠%h[
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,$=+HyICk%V",n?Z8G#G=hM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。[!-国]1{:UwO理gVF)育专业H*#C;中垠h
