如何在gridview中处理PageIndexChanging [英] how to handle PageIndexChanging in gridview

问题描述

当我点击页码时，错误是



GridView'GridView1'触发了未处理的事件PageIndexChanging。

如何处理？

当我尝试

时

  protected   void  GridView2_SelectedIndexChanged（ object  sender，EventArgs e）
 {
 GridView1.PageIndex = e.NewPageIndex; 
 GridView1.DataSource = GetData（）; 
 GridView1.DataBind（）; 
} 

在构建错误期间是

'System.EventArgs'不包含'NewPageIndex'的定义，没有扩展方法'NewPageIndex'接受类型为'System.EventArgs'的第一个参数'（你是否缺少using指令或汇编引用？）

解决方案

试试这个，



在gridview的pageindexChanging属性中，

  protected   void  GridView1_PageIndexChanging（ object  sender，GridViewPageEventArgs e）
 {
 GridView1.PageIndex = e.NewPageIndex; 
 
  //  重新绑定gridview  -  GetSource（），GirdView的数据源 
 GridView1.DataSource = GetSource（）; 
 GridView1.DataBind（）; 
 
} 

希望它有所帮助，请将此标记为答案，如果它可以帮助您



谢谢

试试这个：

 < span class =code-keyword> protected   void  GridView1_PageIndexChanging（ object  sender，GridViewPageEventArgs e ）
 {
 GridView1.PageIndex = e.NewPageIndex; 
 GridView1.DataSource =  //  获取数据源（列表或数据表） 
 GridView1 .DataBind（）;  //  绑定数据 
}

您需要为网格处理PageIndexChanging事件，例如

  protected   void  GridView1_PageIndexChanging（ object  sender，GridViewPageEventArgs e）
 {
 GridView1.PageIndex = e.NewPageIndex; 
  //  绑定网格 
 
} 

When I click the page number then error is

The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.
How to handle it?
When I try
this

protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
        {
            GridView1.PageIndex = e.NewPageIndex;
            GridView1.DataSource = GetData();
            GridView1.DataBind();
        }

during the build error is
'System.EventArgs' does not contain a definition for 'NewPageIndex' and no extension method 'NewPageIndex' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?)

解决方案

try this,

in gridview's pageindexChanging property,

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;

    //rebind your gridview - GetSource(),Datasource of your GirdView
    GridView1.DataSource = GetSource();
    GridView1.DataBind();

}

hope it helps, mark this as answer if it helps you

thanks

Try this:

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataSource = //get datasource (list or datatable)
    GridView1.DataBind(); //bind data
}

You need to handle the PageIndexChanging event for the grid like

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    //Bind grid

}
