推荐答案

试试这个

Try this

<asp:gridview id="myGridView" runat="server" >
 AllowPaging="True" 
 OnPageIndexChanging="myGridView_PageIndexChanging"
 PageSize="5" ></asp:gridview>

protected void myGridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {     

        myGridView.PageIndex = e.NewPageIndex;
        myGridView.DataBind();
    }

我的代码是

My code is

<asp:GridView ID="GridView_Inbox" runat="server" AutoGenerateColumns="False"

                         onrowcommand="GridView_Inbox_RowCommand" AllowPaging="true" PageSize="1" OnPageIndexChanging="GridView_Inbox_PageIndexChanging">
                         <PagerSettings Mode="NumericFirstLast" PageButtonCount="2"  FirstPageText="First" LastPageText="Last"/>
                    <Columns>
                        <asp:BoundField DataField="MESSAGE_ID" HeaderText="Message ID" Visible="false"  />
                        <asp:BoundField DataField="FIRST_NAME" HeaderText="First Name"  />
                        <asp:BoundField DataField="LAST_NAME" HeaderText="Last Name" />
                        <asp:BoundField DataField="MESSAGE_SUBJECT" HeaderText="Subject" />
                        <asp:BoundField DataField="MESSAGE_CONTENT" HeaderText="Message" >
                            <HeaderStyle HorizontalAlign="Center" Width="400px" />
                        </asp:BoundField>
                        <asp:TemplateField>
                            <ItemTemplate>
                                <asp:LinkButton ID="LinkButton_Inbox_Read" runat="server" CommandArgument='<%# Eval("MESSAGE_ID") %>'>Read</asp:LinkButton>
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
                   </asp:GridView>

我的.cs代码是

My .cs code is

protected void GridView_Inbox_RowCommand(object sender, GridViewCommandEventArgs e)
   {
       int MSG_ID = Convert.ToInt32(e.CommandArgument);
       SysATGlobal.DB.ExecuteDMLCommand("UPDATE DSMailBox.HDR_MESSAGES SET READ_STATUS=1 WHERE MESSAGE_ID= " + MSG_ID + " ");
       dt = SysATGlobal.DB.ExecuteSelectQuery("SELECT [INBOX].MESSAGE_CONTENT  from DSMailBox.HDR_MESSAGES [INBOX] INNER JOIN DSProfile.HDR_PROFILE [SENDER] ON [SENDER].[PROFILE_ID] = [INBOX].[SENDER_ID] WHERE [INBOX].[RECEIVER_ID] = " + SysATGlobal.DB.MyProfile.ProfileID + "  AND [INBOX].[MESSAGE_ID]=" + MSG_ID + "", false);
       msg = dt.Rows[0].ItemArray.GetValue(0).ToString();  //Here i get that exception
       TextBox_Inbox.Text = msg;


   }
