Java Set 集合 Set是 Java 集合框架中的一部分，它代表了一个不重复元素的集合。这意味着Set不允许包含重复的元素，每个元素在集合中都是唯一的。Set集合通常用于存储无序的、不重复的对象，例如一组唯一的整数或字符串。Set集合是 Java 中一种非常有用的数据结构，用于存储不重复的元素。本博客介绍了Set集合的基本概念、创建和初始化、基本操作、遍历、不同实现类、性能考虑、使用注意事项、高级用法以及示例代码。希望通过本文的介绍，您对Set集合有了更深入的了解，并能够在实际编程中灵活运用。阅读详情

STM32CubeMX-电机控制2-电机相关配置部分 STM32CubeMX-电机霍尔传感器写在前面的话：之前一直使用库函数，调程序时总会觉得是配置出现问题，要画一些时间去检查配置程序，所以目前转到了STM32CubeMX。写这些内容一方面是整理记录，因为是刚入门，所以难免出现错误，希望能得到大家指正；另一方面是因为自己一个人调试，走了很多弯路，写下来希望能给相同处境的人一些参考。步骤一：电机霍尔传感器接口我目前使用的是STM32F4，电机的... 阅读详情

参考:
http://www.csdn.net/develop/Read_Article.asp?Id=18627

public void Submit_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
string keywordCustCode=txtCustCode.Text.ToString();

string selectStatement = " SELECT * FROM cust where CUST_CODE like '%" + keywordCustCode + "%' ";
theOffice.components.ModulesPublic cust = new theOffice.components.ModulesPublic();
DataSet ds=cust.GetData(selectStatement);
this.dgCust.DataSource = ds.Tables["Cust"].DefaultView;
this.dgCust.DataBind();
Session["table"] = ds.Tables["Cust"].DefaultView;//保存数据
}

void dgCust_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
if (Session["table"] != null) {
dgCust.CurrentPageIndex=e.NewPageIndex;
dgCust.DataSource = Session["table"];//取得查询数据。
this.dgCust.DataBind();
}
}

用Session解决，具体看上面的代码和注释。

private void DataGridList_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
DataGridList.DataSource=ds;//ds is a datatable
DataGridList.CurrentPageIndex = e.NewPageIndex;
DataGridList.DataBind();
}

应该把ShowStartsPage()放到DepArticleCatalogueDataBind()里面，我疏忽了。

这个怎么样，首页，下一页，上一页，末叶。添数字直接到指定页，datagrid自己分页。
private void DepArticleCatalogueDataBind()
{
ArticleQuery departmentArticleGet = new ArticleQuery();
dgDepArticleCatalogue.DataSource = departmentArticleGet.GetDepartmentArticle(Convert.ToInt16(Request["DepartmentID"]));
dgDepArticleCatalogue.DataBind();

Editiones AllEditionGet = new Editiones();
dgEditiones.DataSource = AllEditionGet.GetAllEditiones();
dgEditiones.DataBind();
}

// 显示第几页、共几页
private void ShowStartsPage()
{
pageCount.Text = Convert.ToString(dgDepArticleCatalogue.PageCount);
pageNumber.Text = Convert.ToString(dgDepArticleCatalogue.CurrentPageIndex+1);
}

private void first_Click(object sender, System.EventArgs e)
{
dgDepArticleCatalogue.CurrentPageIndex = 0;
DepArticleCatalogueDataBind();
}

private void next_Click(object sender, System.EventArgs e)
{
if (dgDepArticleCatalogue.CurrentPageIndex < dgDepArticleCatalogue.PageCount -1)
{
dgDepArticleCatalogue.CurrentPageIndex++;
DepArticleCatalogueDataBind();
}
}

private void prev_Click(object sender, System.EventArgs e)
{
if (dgDepArticleCatalogue.CurrentPageIndex > 0)
{
dgDepArticleCatalogue.CurrentPageIndex--;
DepArticleCatalogueDataBind();
}
}

private void last_Click(object sender, System.EventArgs e)
{
dgDepArticleCatalogue.CurrentPageIndex = dgDepArticleCatalogue.PageCount-1;
DepArticleCatalogueDataBind();
}

private void gotoPage_Click(object sender, System.EventArgs e)
{
try
{
int pageNumber = Convert.ToInt16(pageNum.Text)-1;
if (pageNumber >= 0 && pageNumber < dgDepArticleCatalogue.PageCount)
{
dgDepArticleCatalogue.CurrentPageIndex = pageNumber;
}
DepArticleCatalogueDataBind();
}
catch
{
pageNum.Text = "输入错误";
}
}

private void dgDepArticleCatalogue_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
dgDepArticleCatalogue.CurrentPageIndex = e.NewPageIndex;
DepArticleCatalogueDataBind();
}
}

關鍵是：DataGrid.CurrentPageIndex = e.NewPageIndex

DataGrid支持自动分页，设置一下，三行代码就搞定了。
private void DataGrid1_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
DataGrid1.CurrentPageIndex =e.NewPageIndex ;
DataGrid1.DataSource=((DataSet)ho.Search((String)ViewState["sql"])).Tables["search"].DefaultView;
DataGrid1.DataBind();
}

一个功能齐全的DataGrid分页例子

--------------------------------------------------------------------------------

下面的这个例子提供了DataGrid的分页功能。aspx代码和Cohe Behind代码分别如下，注意更改数据录连接字符串。结果如下：
