You can try a TemplateField like this for GridView1 (primary GridView)

<asp:TemplateField>
    <ItemTemplate>
        <asp:LinkButton runat="server" ID="LinkButton1" CommandName="cmdName"  CommandArgument='<%# Eval("IdColumn") %>' > LinkButton</asp:LinkButton>
    </ItemTemplate>
</asp:TemplateField>

and in GridView1’s RowCommand, you can get the CommandArgument and setup the DataSource for GridView2 (child GridView).

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if(e.CommandName = "cmdName")
    {
        var arg = e.CommandArgument;

        // use arg to filter GridView2's DataSource
        GridView2.DataSource = FilteredDataSource;
        GridView2.DataBind();
        // show GridView2 if it's hidden.
    }
}
