DBGridEh实现单击标题栏排序方法

1.添加引用:DBClient2.置DBGridEh控件属性:设置dghAutoSortMarking属性为true 设置希望排序的Column的TitleButton属性为true3.//表格排序过程
procedure OrderGrid(dataSet:TClientDataset;orderField:string);
var
i:integer;
begin
if dataSet.IndexFieldNames<>'' then
begin
i:=TClientDataSet(DataSet).IndexDefs.IndexOf('i'+orderField);
if i=-1 then
begin
with Dataset.IndexDefs.AddIndexDef do
begin
Name:='i'+orderField;
Fields:=orderField;
DescFields:=orderField;
end;
end;
dataSet.IndexFieldNames:='';
dataSet.IndexName:='i'+orderField;
end
else
begin
dataSet.IndexName:='';
dataSet.IndexFieldNames:=orderfield;
end;
end;4.在DBGridEh的OnTitleClick事件中调用OrderGrid(DM.ClientDataset,Column.FieldName);
