 <   asp：GridView     ID   =  GridView3    runat   =  server    DataKeyNames   =  ClassesID    CssClass   =  MGRID

           GridLines   = 水平    OnRowDataBound   =  GridView3Bound   宽度  =  100％ >  
 <  列 >

                           HeaderStyle-Width   =   350px    HeaderStyle-Horizo​​ntalAlign   = 对    ItemStyle-Horizo​​ntalAlign   = 右    /  >  
 <   asp：BoundField     DataField   =  per    HeaderText   = ％    SortExpression   = 空缺  
   
                           HeaderStyle-Width   =  350px    HeaderStyle-Horizo​​ntalAlign   = 右    ItemStyle-Horizo​​ntalAlign   = 右    /  >  
 
 <   asp：TemplateField     ItemStyle-Horizo​​ntalAlign   = 右    HeaderStyle-Width   =  50px    ItemStyle-Width   =  30px >  
 <   ItemTemplate  >  
 <   asp：ImageButton     ID   =  pri2   宽度  =  30px   高度  =  30px    CommandName   = 选择  
   
                              < span class =code-attribute>             CommandArgument   ='  <％ #Eval（  ClassesID）％> '    CausesValidation   =  False    ImageUrl   =  〜/ Images / printer.png  
   
                                           runat   = 服务器    /  >  
 <   / ItemTemplate  >  
 <   / asp： TemplateField  >  
 
 <   asp：TemplateField    可见  =  false >  
 <   ItemTemplate  >  
 <   asp：标签    ID   =  ClassesID    runat   = 服务器   可见  =  false   文字  ='  <％ #Bind（  ClassesID）％> ' >  <   / asp：标签 >  
 < ;   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 
 <   /列  >  
 
 <   / asp：GridView  >  

Vb代码： - < br $> b $ b

 受保护的  Sub  GridView3_SelectedIndexChanged（ ByVal  sender 作为 对象， ByVal  e  As  System.EventArgs） Handles  GridView3.SelectedIndexChanged 
 
 
 
  Dim  i  As   Integer  = GridView3.SelectedIndex 
 
  Dim  DataKey  As   String  = GridView3.DataKeys（GridView3.SelectedIndex） .Value 
 Session（  ClassesID）= DataKey 
 结束  Sub  

解决方案

您需要添加RowCommand事件并在事件内检查命令名称。例如，检查以下CP提示



按钮单击上的gridview rowcommand示例 [ ^ ]

和行命令的MSDN文档 [ ^ ]

    PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt" AutoGenerateColumns="false"

    GridLines="Horizontal" OnRowDataBound="GridView3Bound" Width="100%">
    <Columns>

        <asp:TemplateField>
            <ItemTemplate>
                <asp:ImageButton ID="ImageButton2" runat="server" Style="cursor: pointer"  ImageUrl="~/images/plus.png" CommandName="Select" OnClick="Plus"/>

        <asp:BoundField DataField="P" HeaderText="Present" SortExpression="noofroom"

            HeaderStyle-Width="350px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" />
        <asp:BoundField DataField="a" HeaderText="Absent" SortExpression="full"

            HeaderStyle-Width="350px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" />
        <asp:BoundField DataField="per" HeaderText="%" SortExpression="Vacant"

            HeaderStyle-Width="350px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" />

        <asp:TemplateField ItemStyle-HorizontalAlign="Right" HeaderStyle-Width="50px" ItemStyle-Width="30px">
            <ItemTemplate>
                <asp:ImageButton ID="pri2" Width="30px" Height="30px" CommandName="Select"

                    CommandArgument='<%# Eval("ClassesID") %>' CausesValidation="False" ImageUrl="~/Images/printer.png"

                    runat="server" />
            </ItemTemplate>
        </asp:TemplateField>

        <asp:TemplateField Visible="false">
            <ItemTemplate>
                <asp:Label ID="ClassesID" runat="server" Visible="false" Text='<%# Bind("ClassesID") %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>

    </Columns>

</asp:GridView>

Vb Code:-

Protected Sub GridView3_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView3.SelectedIndexChanged
      

      
        Dim i As Integer = GridView3.SelectedIndex

        Dim DataKey As String = GridView3.DataKeys(GridView3.SelectedIndex).Value
        Session("ClassesID") = DataKey
    End Sub

解决方案

you need to add RowCommand event and inside the event check for the command name. for example check below CP Tip
