GridView自帶的分頁功能實現(xiàn)：
要實現(xiàn)GrdView分頁的功能
操作如下：
-
更改GrdView控件的AllowPaging屬性為true。
-
更改GrdView控件的PageSize屬性為 任意數(shù)值（默認為10）
-
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(shè)置好了，從頁面上也能看到分頁樣式。
現(xiàn)在開始實現(xiàn)分頁的功能：
-
在<<asp:GridView ID=......>后添加，OnPageIndexChanging="GridView1_PageIndexChanging"
-
在對應(yīng)的aspx.cs中添加：
|
1

5
|
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e){ GridView1.PageIndex = e.NewPageIndex; InitPage(); //重新綁定GridView數(shù)據(jù)的函數(shù)} |
