Could you tell me why I get the error "GridView" GridView1? RowUpdating which was not processed? "

I managed to solve the initial problem of the inability to insert records sequentially, but a new error message appears.

Now I get The GridView 'GridView1' fired event RowUpdating which wasn't handled.

This error occurs when I click the Refresh button to update the recording line.

First click the "Edit" button. This provides the Update / Cancel buttons.

When I click the Refresh button, I get the above error.

My first assumption was that gridview is necessary for RowUpdating, but after adding (see the markup code), still getting the same error.

This is a little disappointing.

Here is the code.

 Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs) Dim dd As DropDownList = DirectCast(GridView1.Rows(e.RowIndex).FindControl("ddlstatus"), DropDownList) e.NewValues("status") = dd.SelectedItem.Text End Sub

Markup:

  <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="False" DataKeyNames="reqnum" AllowPaging="True" CellPadding="4" ForeColor="#333333" GridLines="None" Visible="True" OnRowDataBound="gvRowDataBound" OnRowEditing="GridView1_RowEditing" onrowupdating="GridView1_RowUpdating" EnableViewState="False" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True"> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <Columns> <asp:BoundField DataField="rownum" HeaderText="rownum" InsertVisible="False" ReadOnly="True" SortExpression="rownum" /> <asp:BoundField DataField="reqnum" HeaderText="reqnum" SortExpression="reqnum" /> <asp:BoundField DataField="reqrecdate" HeaderText="reqrecdate" SortExpression="reqrecdate" /> <asp:BoundField DataField="reqrecfrom" HeaderText="reqrecfrom" SortExpression="reqrecfrom" /> <asp:BoundField DataField="skillsets" HeaderText="skillsets" SortExpression="skillsets" /> <asp:BoundField DataField="application" HeaderText="application" SortExpression="application" /> <asp:BoundField DataField="hoursperweek" HeaderText="hoursperweek" SortExpression="hoursperweek" /> <asp:BoundField DataField="fromdate" HeaderText="fromdate" SortExpression="fromdate" /> <asp:BoundField DataField="todate" HeaderText="todate" SortExpression="todate" /> <%-- <asp:BoundField DataField="status" HeaderText="status" SortExpression="status" />--%> <asp:TemplateField HeaderText="status"> <EditItemTemplate> <asp:DropDownList id="ddlstatus" CssClass="dropdown" DataSourceID="DSforDDL" runat="server"> <asp:ListItem Text="none" Value=""></asp:ListItem> <asp:ListItem>Not Started</asp:ListItem> <asp:ListItem>Pending</asp:ListItem> <asp:ListItem>Completed</asp:ListItem> </asp:DropDownList> </EditItemTemplate> <ItemTemplate> <asp:Label ID="lblstatus" runat="server" Text='<% #Bind("status") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="statusupdate" HeaderText="statusupdate" SortExpression="statusupdate" /> <asp:BoundField DataField="statusupby" HeaderText="statusupby" SortExpression="statusupby" /> </Columns> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <EditRowStyle BackColor="#999999" /> <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT Distinct [rownum],[reqnum], [reqrecdate], [reqrecfrom], [skillsets], [application], [hoursperweek], [fromdate], [todate], [status], [statusupdate], [statusupby] FROM [Term] ORDER BY [reqnum]" UpdateCommand="INSERT INTO Term(reum, reqrecdate, reqrecfrom, skillsets, application, hoursperweek, fromdate, todate, status, statusupby, statusupdate) VALUES (@reum,@reqrecdatelbltxt, @reqrecfromlbltxt, @skillsets, @application, @hoursperweek,@fromdate,@todate, @status, @lognametxt, @logdatetxt)" <DeleteParameters> <asp:Parameter Name="rownum" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="reqnum" Type="String" /> <asp:Parameter DbType="DateTime" Name="reqrecdate" /> <asp:Parameter Name="reqrecfrom" Type="String" /> <asp:Parameter Name="skillsets" Type="String" /> <asp:Parameter Name="application" Type="String" /> <asp:Parameter Name="hoursperweek" Type="Int32" /> <asp:Parameter DbType="DateTime" Name="fromdate" /> <asp:Parameter DbType="DateTime" Name="todate" /> <asp:Parameter Name="status" Type="String" /> <asp:Parameter DbType="DateTime" Name="statusupdate" /> <asp:Parameter Name="statusupby" Type="String" /> <asp:Parameter Name="rownum" Type="Int32" /> </UpdateParameters> </asp:SqlDataSource>

Many thanks for your help.

GridView tracks handlers to make sure something has been added to deal with the update intentionally.

If you don’t manually enter “AddHandler”, something else in the code, I don’t see a cluster of handles for your event method that would intercept the event that was generated.
