我在一个页面上有两个gridviews 第一个datagrid(requestgrid) 是通过使用具有参数的存储过程填充的，并且该参数由查询字符串提供。

仅当我在第一个数据网格中选择一行时才需要显示页面中的另一个网格。我能够使用以下代码从选择中获取 requestid

void Requesttbl_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName.Equals("clickrequestid"))
            {

                Requesttbl.Visible = false;
                int requestid = (int)e.CommandArgument;
               }
        }

我的问题是如何使用此 requestid 将其作为参数传递给第二个 gridview

下面的代码是我在标记页面中的第二个网格视图代码

<asp:GridView ID="SelectedReports" runat="server" AutoGenerateColumns="False" 
            DataSourceID="showselectedreports" EnableModelValidation="True">
            <Columns>
                <asp:BoundField DataField="Requestid" HeaderText="Requestid" 
                    SortExpression="Requestid" />
                <asp:BoundField DataField="rptdesctext" HeaderText="rptdesctext" 
                    SortExpression="rptdesctext" />
                <asp:BoundField DataField="Completeddt" HeaderText="Completeddt" 
                    SortExpression="Completeddt" />
                <asp:BoundField DataField="Analyst" HeaderText="Analyst" ReadOnly="True" 
                    SortExpression="Analyst" />
            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="showselectedreports" runat="server" 
            ConnectionString="<%$ ConnectionStrings:UnderWritingConnectionString %>" 
            SelectCommand="ShowCustomerSelectedRequests" 
            SelectCommandType="StoredProcedure">
            <SelectParameters>
how do i use the requestid as a parameter here**strong text**
                           </SelectParameters>
        </asp:SqlDataSource>

提前致谢

此示例可能会对您有所帮助，因为我从一个网格视图中获取值 CountryID 并在选定的国家 ID 上填充其他值，根据您的要求进行更改。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="CountryID" DataSourceID="SqlDataSource1" 
                onselectedindexchanged="GridView1_SelectedIndexChanged">
                <Columns>
                    <asp:CommandField ShowSelectButton="True" />
                    <asp:BoundField DataField="CountryID" HeaderText="CountryID" ReadOnly="True" 
                        SortExpression="CountryID" />
                </Columns>
            </asp:GridView>
            <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:testConnectionString %>" 
            SelectCommand="SELECT [CountryID], [Country] FROM [Tbl_Country]">
        </asp:SqlDataSource>
            <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" 
                DataKeyNames="CountryID" DataSourceID="SqlDataSource2">
                <Columns>
                    <asp:BoundField DataField="CountryID" HeaderText="CountryID" ReadOnly="True" 
                        SortExpression="CountryID" />
                    <asp:BoundField DataField="Country" HeaderText="Country" 
                        SortExpression="Country" />
                </Columns>
            </asp:GridView>
            <asp:SqlDataSource ID="SqlDataSource2" runat="server" 
                ConnectionString="<%$ ConnectionStrings:testConnectionString %>" 
                SelectCommand="SELECT * FROM [Tbl_Country] WHERE ([CountryID] = @CountryID)">
                <SelectParameters>
                    <asp:ControlParameter ControlID="GridView1" Name="CountryID" 
                        PropertyName="SelectedValue" Type="Int32" />
                </SelectParameters>
            </asp:SqlDataSource>
