Question

我有一个带有复选框的转发器，我想从表中删除子类别中的项目/记录，并选中复选框。任何想法？

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

我收到了错误：

'='附近的语法不正确。描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。异常详细信息：System.Data.SqlClient.SqlException：'='附近的语法不正确。

// 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!");
               }
          }

您的以下行中有错误

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);

删除转发器中的选中复选框
