Question

我在页面上有两个网格视图第一个数据网格（requestgrid）通过使用存储过程填充，该存储过程具有参数，该参数由查询字符串提供。

当我在第一个datagrid中选择一行时，只需要显示页面中的其他网格。我可以使用下面的代码从选择中获取请求

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>

此示例可能对您有所帮助，因为我从一个网格视图中获取值CountryID并在所选国家/地区ID上填充其他ID，并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>
