解决方案

我遇到了同样的问题。问题出在你的datatbind逻辑上。



请检查您的代码是否存在以下问题：



1.网格数据绑定逻辑必须在Page_Load中事件。



2.它应该包含在if（！Page.IsPostBack）{//数据绑定逻辑这里; }

使用这个

 <  列 >  
 < ;   asp：TemplateField     ItemStyle-Width   =  90px >  
 <   EditItemTemplate  >  
 <   asp：ImageButton     ID   =  imgbtnUpdate    CommandName   = 更新    runat   =  server < span class =code-attribute>   ImageUrl   = 〜/ Images / update.png  
   
                                                                                                                                  工具提示  = 更新    /  >

                              < span class =code-attribute>                          < span class =code-attribute>                                                      < span class =code-attribute>                    工具提示  = 取消    /  >

解决方案

I encountered the same issue .The problem is with your datatbind logic.

Please check your code for these issues:

1. The grid databind logic must be in Page_Load event.

2. It should be enclosed inside if(!Page.IsPostBack) { //databind logic here; }

use this

<Columns>
                                                    <asp:TemplateField ItemStyle-Width="90px">
                                                        <EditItemTemplate>
                                                            <asp:ImageButton ID="imgbtnUpdate" CommandName="Update" runat="server" ImageUrl="~/Images/update.png"

                                                                ToolTip="Update" />
                                                            <asp:ImageButton ID="imgbtnCancel" runat="server" CommandName="Cancel" ImageUrl="~/Images/Cancel.png"

                                                                ToolTip="Cancel" />
                                                        </EditItemTemplate>
                                                        <ItemTemplate>
                                                            <asp:ImageButton ID="imgbtnEdit" CommandName="Edit" runat="server" ImageUrl="~/Images/Edit.png"

                                                                ToolTip="Edit" />
                                                            <asp:ImageButton ID="imgbtnDelete" CommandName="Delete" Text="Edit" runat="server"

                                                                ImageUrl="~/Images/delete.png" ToolTip="Delete" Height="20px" Width="20px" />
                                                        </ItemTemplate>
                                                        <FooterTemplate>
                                                            <asp:ImageButton ID="imgbtnAdd" runat="server" ImageUrl="~/Images/AddNewitem.png"

                                                                CommandName="AddNew" />
                                                        </FooterTemplate>
                                                    </asp:TemplateField>
