Asp.net 启用分页时如何获取Gridview的所有行？？

启用分页时如何获取gridview的所有行

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

它只允许获取当前的获取行，而不是整个gridview行。

我们暂时禁用分页，并将重新绑定网格，以便现在我们可以访问数据源中的所有记录，而不仅仅是当前页面记录

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

一旦gridview与所有记录绑定，就可以遍历gridview行

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

完成任务后，我们将重新启用分页并重新绑定网格

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

以下是应对您的情况的方法：

protected void Page_Load(object sender, EventArgs e)
{
    GridView2.AllowPaging = false;
    GridView2.DataBind(); 

    // You can select some checkboxex on gridview over here..

    GridView2.AllowPaging = true;
    GridView2.DataBind(); 
}

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

更好的方法是在页面顶部（gridview之外）放置一个隐藏字段，单击复选框后，您应该在隐藏字段中以逗号分隔的格式放置相关id或某些值。提交表单时，您可以使用逗号作为分隔符拆分隐藏的字段值字符串。使用以下代码并禁用GridView分页

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

GridView1.AllowPaging=false； GridView1.DataBind（）

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

在页面加载或某些其他事件中，如果您希望显示所有Gridview行，则启用分页时无法显示所有行。但您可以将

Allowpaging=false

protected void Page_Load(object sender, EventArgs e)
{
Gridviewname.AllowPaging=false;
}

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

或

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

在从网格中获取数据之前，只需编写

yourGridName.AllowPaging=false;

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

在数据写入之后

yourGridName.AllowPaging=true;

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

如果您的函数是GetDataFromGrid（），那么您应该这样做

protected void Page_Load(object sender, EventArgs e)
{
yourGridName.AllowPaging=false;
GetDataFromGrid() 
yourGridName.AllowPaging=true;
}

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

您可以使用下面的命令，我正在项目中使用这些命令。它的逻辑很简单，你浏览所有的页面，在每一页你浏览所有的行。您还可以在执行此操作之前获取当前页面，并在循环所有内容之后返回该页面；）

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

//获取当前页面索引，以便在执行命令后返回此处
int a=GridView1.PageIndex；
//循环浏览所有页面
对于（int i=0；i
使用以下代码获取
e.CommandArgument
的值。我一定会解决你的问题

//Get Current Page Index so You can get back here after commands
                int a = GridView1.PageIndex;
    //Loop through All Pages
                for (int i = 0; i < GridView1.PageCount; i++)
                {
    //Set Page Index
                    GridView1.SetPageIndex(i);
    //After Setting Page Index Loop through its Rows
                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        //Do Your Commands Here
                    }
                }
    //Getting Back to the First State
                GridView1.SetPageIndex(a);

  protected void GridViewID_RowCommand(object sender, GridViewCommandEventArgs e)
  {
         if (e.CommandName == "GetDetail")
         {
            int index = Convert.ToInt32(e.CommandArgument) % GridViewID.PageSize; // !Important

            GridViewRow row = GridViewID.Rows[index];
         }
 }

难道你不能从
数据源中获取所有行吗？这意味着你想知道如何禁用分页吗？；）这背后的目的是什么..？实际上gridview将出现在pageload上，然后我在gridview上选择一些复选框。。。然后我将进入gridview的第二页，我尝试选择其他复选框，但当我保存所有数据时，它只保存当前页面数据，而不是所有gridview页面。我将获得所有选中该复选框的行。grdSupplierSearch.Rows.Cast（）。其中（a=>（（复选框）a.FindControl（“ckbSelectCompany”）。选中和选中的公司名称。包含（（标签）a.FindControl（“lblCompanyNameGrid”）.Text））.ToList（）；但它只允许保存当前页面数据，而不允许保存gridview的其他页面。谢谢@Vishal Suthar，完成了。如果它真的有帮助，那么您可以接受答案。请参阅：（）是的，如果不调用databind（），则无法工作。谢谢，这对我也有帮助。这种方法有效，但使用起来有风险。如果有人对代码做了任何更改，但没有意识到分页在哪里被关闭，则可能会使某些人的web浏览器崩溃。设置页面索引更安全。这是更简单的方法。关闭或打开AllowPaging都充满了问题，尤其是如果您不想打乱客户端正在查看的页面（看到GridView突然扩展和收缩看起来不太好），如果您在所有页面上都有复选框，并且有些页面被勾选或未勾选，该怎么办？还有很多，ViewState控制一切会变得混乱。到目前为止，这是更好的答案。我甚至想说唯一的答案。不要试图轻视公认的回答者，因为它从技术上回答了问题，但这是一种不太“粗鲁”的方式，也是一种更专业的做事方式。任何阅读这篇文章的人都应该在接受答案的基础上使用这种方法。别怀疑。
