Question

我有一个下拉列表和一个gridview外的按钮，用于控制要在gridview中显示的数据。另外，我在gridview中进行了“编辑”。单击gridview中的“编辑”后，如何保留下拉列表和gridview数据的值？

 <asp:DropDownList ID="ddl" runat="server">
        <asp:ListItem>All</asp:ListItem>
        <asp:ListItem>Yes/asp:ListItem>
        <asp:ListItem>No</asp:ListItem>
</asp:DropDownList>
<asp:Button ID="btn" runat="server" Text="Search" onclick="btnOnClick" />

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
        OnRowEditing="gvUpdateMsg_Rowediting" OnRowUpdating="gvUpdateMsg_Rowupdating" 
        OnRowCancelingEdit="gvUpdateMsg_Cancelingedit">
        <Columns>
            <asp:TemplateField ShowHeader="False">
                <EditItemTemplate>
                    <asp:LinkButton ID="btnUpdate" runat="server" CausesValidation="True" CommandName="Update"
                        Text="Confirm"></asp:LinkButton>
                    <asp:LinkButton ID="btnCancel" runat="server" CausesValidation="False" CommandName="Cancel"
                        Text="Cancel"></asp:LinkButton>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:LinkButton ID="btnEdit" runat="server" CausesValidation="False" CommandName="Edit"
                        Text="Reply"></asp:LinkButton>
                </ItemTemplate>
            </asp:TemplateField>

           <asp:TemplateField>
                <ItemTemplate>
                  ........
                </ItemTemplate>
            </asp:TemplateField>

            .......


     </Columns>
    </asp:GridView>

将“OnClick”事件添加到您的btnEdit按钮，如下所示：

<asp:LinkButton ID="btnEdit" runat="server" CausesValidation="False"
CommandName="Edit" Text="Reply" OnClick="btnEdit_Click"></asp:LinkButton>

在背后的代码中：

protected void btnEdit_Click(object sender, EventArgs e)
{
    GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
    LinkButton btnEdit = (LinkButton)clickedRow.FindControl("btnEdit");
    string any_data_for_gridview = clickedRow.Cells[1].Text; //change number 1
    string any_data_for_ddl = ddl.SelectedValue.ToString();
}

在gridview中单击“编辑”后保留下拉列表（在gridview外部）选择的值
