'GridView1' fired event PageIndexChanging which wasn't handled

问题:

I am using a gridview and I want to use paging. I have already set allow paging to true and page size to 5. I can see the numbers at the base of my gridview, but when i click on a number to move to respective page, it throws an error saying:

The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.

Code:

 <asp:GridView ID="GridView1" runat="server" CellPadding="5"      AutoGenerateColumns="False" AllowPaging="True" DataKeyNames="contact_id"      onrowcancelingedit="GridView1_RowCancelingEdit"      onrowediting="GridView1_RowEditing" onrowupdating="GridView1_RowUpdating"      PageSize="5">     <Columns>         <asp:TemplateField HeaderText="contact_id">             <ItemTemplate>                 <asp:Label ID="Label3" runat="server" Text='<%# Eval("contact_id") %>'></asp:Label>             </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="name">             <ItemTemplate>                 <asp:Label ID="Label4" runat="server" Text='<%# Eval("name") %>'></asp:Label>             </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="address">             <ItemTemplate>                 <asp:Label ID="Label5" runat="server" Text='<%# Eval("address") %>'></asp:Label><br />                 <asp:Label ID="Label6" runat="server" Text='<%# Eval("city") %>'></asp:Label><br />                  <asp:Label ID="Label7" runat="server" Text='<%# Eval("state") %>'></asp:Label><br />            <asp:Label ID="Label8" runat="server" Text='<%# Eval("pincode") %>'></asp:Label>              </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="email">             <ItemTemplate>                 <asp:Label ID="Label9" runat="server" Text='<%# Eval("email") %>'></asp:Label>             </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="mobile">             <ItemTemplate>                 <asp:Label ID="Label10" runat="server" Text='<%# Eval("mobile") %>'></asp:Label>             </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="context">             <ItemTemplate>                 <asp:Label ID="Label11" runat="server" Text='<%# Eval("context") %>'></asp:Label>             </ItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="status">             <ItemTemplate>                 <asp:Label ID="Label12" runat="server" Text='<%# Eval("status") %>'></asp:Label>             </ItemTemplate>             <EditItemTemplate>                 <asp:DropDownList ID="DropDownList1" runat="server">                 <asp:ListItem>PENDING</asp:ListItem>                 <asp:ListItem>OK</asp:ListItem>                 </asp:DropDownList>             </EditItemTemplate>         </asp:TemplateField>         <asp:TemplateField HeaderText="Edit" ShowHeader="False">             <ItemTemplate>                 <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"                      CommandName="Edit" Text="Edit"></asp:LinkButton>             </ItemTemplate>             <EditItemTemplate>                 <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True"                      CommandName="Update" Text="Update"></asp:LinkButton>                 &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False"                      CommandName="Cancel" Text="Cancel"></asp:LinkButton>             </EditItemTemplate>             <ItemStyle CssClass="button" />         </asp:TemplateField>     </Columns>     <PagerStyle HorizontalAlign="Left" VerticalAlign="Middle" /> </asp:GridView> 

回答1:

You will have to handle the PageIndexChanging event for the grid

Something like

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

回答2:

It will not work if you enable paging. You also need to write the event handler for PageIndexChangeEvent. Check this link: http://forums.asp.net/post/1177923.aspx

回答3:

You would need to code "PageIndexChanging" event to make it work. Add an event handler for the PageIndexChanging where you set the GridView.CurrentPage = e.NewPage...

回答4:

Add one more event in HTML mark up for pagging.

OnPageIndexChanging="GridView1_PageIndexChanging" 

Now handle same event from code behind

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) {     //Your code }
