删除复选框中的复选框

我有一个复选框的中继器，我想删除子表中的项目/记录从复选框中选中的项目/记录。有任何想法吗？删除复选框中的复选框

表结构：
软件 CategoryID=100, SubCategoryID=NULL (main category) ASP.NET CategoryID=100, SubCategoryID=100 (sub category)

我得到错误：

// select all 
protected void btnSelectAll_Click(object sender, EventArgs e) 
    { 
     foreach (RepeaterItem ri in rpCategory.Items) 
     { 
CheckBox checkBoxApproved = ri.FindControl("checkBoxApproved") as CheckBox; 
      if (checkBoxApproved != null) 
      { 
       if (checkBoxApproved.Checked == true) 
       { 
        checkBoxApproved.Checked = false; 
       } 
       else 
       { 
        checkBoxApproved.Checked = true; 
       } 
      } 
     } 
    } 

    // delete all 
    protected void btnDelete_Click(object sender, EventArgs e) 
     { 
      for (int i = 0; i < rpCategory.Items.Count; i++) 
      { 
       CheckBox CheckBox1 = (CheckBox) 
       rpCategory.Items[i].FindControl("checkBoxApproved"); 

       if (((CheckBox)rpCategory.Items[i].FindControl("checkBoxApproved")).Checked) 
       { 
        CheckBox CheckBox = (CheckBox)rpCategory.Items[i].FindControl("checkBoxApproved"); 

        SqlConnection cnn = system.baglan(); 
        SqlCommand cmd = new SqlCommand("DELETE FROM TBLCATEGORIES where SubCategoryID="+CategoryID, cnn); 
        cmd.ExecuteNonQuery(); 
        Response.Redirect("SubCategories.aspx?Message=Success!"); 
       } 
      }

阿霉素空间后SubCategoryID后，检查值，您需要更改'SubCategoryID = + “CategoryID'到'SubCategoryID =” + CategoryID'！ '+'在'''错误的一边，我想知道这是为什么这个编译... –

的

SqlCommand cmd = new SqlCommand("DELETE FROM TBLCATEGORIES where 'SubCategoryID=+"CategoryID, cnn);'

将其更改为

SqlCommand cmd = new SqlCommand("DELETE FROM TBLCATEGORIES where SubCategoryID=" +CategoryID, cnn);
