GridView自帶的分頁功能實現：

要實現GrdView分頁的功能
操作如下：
1、更改GrdView控件的AllowPaging屬性為true。
2、更改GrdView控件的PageSize屬性為任意數值（默認為10）
3、更改GrdView控件的PageSetting->Mode為Numeric等（默認為Numeric）該屬性為分頁樣式。
GridView屬性設置好了，從頁面上也能看到分頁樣式。

現在開始實現分頁的功能：

1、在<<asp:GridView ID=......>后添加，OnPageIndexChanging="GridView1_PageIndexChanging"
2、在對應的aspx.cs中添加：
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
InitPage(); //重新綁定GridView數據的函數
}
3、
GridView1.PageIndex = e.NewPageIndex;
完了之后再重新綁定一下GridView。

GridView添加CheckBox列實現全選/全部取消功能

首先GridView編輯模版，在模板上添加CheckBox控件，之后將新添加列字段轉換為TemplateFiled

if (CheckBox2.Checked == true)
{
cbox.Checked = true;
}

{

}
}
}
protected void Button2_Click(object sender, EventArgs e)
{
sqlcon = new SqlConnection(strCon);
SqlCommand sqlcom;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (cbox.Checked == true)
{

string sqlstr = "delete from 飛狐工作室 where 身份證號碼='" + GridView1.DataKeys[i].Value + "'";
sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
}
}
bind();
}
protected void Button1_Click(object sender, EventArgs e)
{
CheckBox2.Checked = false;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
cbox.Checked = false;
}
}
public void bind()
{
string sqlstr = "select top 5 * from 飛狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "tb_Member");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份證號碼" };
GridView1.DataBind();
sqlcon.Close();
}
}
