在EXtgrid类中
public delegate bool DeleteEvent(string selStr);
public DeleteEvent OnDeleteEvent{get;set;}
protected void btnDelete_Click(object sender, EventArgs e) { DoDelete(); }
public void DoDelete() {
string sel = GetRowsSelected();
if (sel == "")
{ Alert.Show("请选择一条数据!");
return; }
if (OnDeleteEvent != null)//委托给使用者实现
{
try
{
if (OnDeleteEvent(sel))
{ Alert.Show("删除成功!"); BindGrid(); }
else
{ Alert.Show("删除失败!"); } }
catch
{ Alert.Show("删除失败!数据存在引用关系,请查找"); } } }
在继承Extgrid类的页面中,实现委托删除操作
private bool deleteRecord(string recordID)
{
int flag = 0;
try
{
string wherecondition="";
wherecondition=" where SEQ in("+recordID+")";
t_access = new B_CardAccess(this.connStr);
flag=t_access.ExecuteDelRecord(wherecondition);
this.Log("删除");
}
catch
{
}
if (flag > 0)
{
return true;
}
else
{
return false;
}
}
