如何根据另一个转发器中的radiobuttonlist过滤转发器项目的数据

Question

I have a shopping page where I am displaying filters on the left and side such as category, price, color, etc. and displaying products on the right hand side. I am using repeater for filter data ie using radio buttonlist to filter data and trying to filter data in another repeater based on radiobuttonlist in repeater1. this is my page look I want to filter products based on semisubcategory

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <td style="border-right:groove;">
            <h4>Semi Sub Category</h4>
            <asp:RadioButtonList ID="semiSubCat1" 
                 DataSource='<%# Eval("subquery1") %>'
                 DataTextField="semiSubCategoryName"
                 DataValueField="semiSubCategoryId" runat="server">
            </asp:RadioButtonList>
       </td>
    </ItemTemplate>
  </asp:Repeater>

Code Behind

protected void Page_Load(object sender, EventArgs e)
{        
    var Rquery = from p in dc.ProductDatas
                 select new
                 {
                     p.productId,
                     p.proName,
                     subquery1 = from ps in dc.SemiSubCategories
                                select new { 
                                ps.semiSubCategoryId,
                               ps.semiSubCategoryName,
                                },
                    subquery2 = from sp in dc.Sizes 
                                select new {
                                sp.sizeId,
                                sp.sizeNumber,
                                },
                 };
    Repeater1.DataSource = Rquery;
    Repeater1.DataBind();
}
protected void semiSubCat_SelectedIndexChanged(object sender, EventArgs e)
{
    if (semiSubCat.SelectedIndex > 0)
    {
        string query = string.Format("select * from ProductData join SemiSubCategory on ProductData.semiSubCategory equals SemiSubCategory.semiSubCategoryId where semiSubCategoryName == semiSubCat.SelectedItem.Value"
                                                                    , sender, e);
        query.ToList();
    }
}

Try using OnCheckedChanged event

protected void RadioButton_CheckedChanged(object sender, System.EventArgs e)
{
    
   //Filter

}
