在ObjectDataSource上使用Selection属性而不是“SelectMethod”?

也许我错过了什么。但如果你想把财产转让给 SelectMethod ,您必须将其设置为 get_{Property Name} .

如果要尝试分配SelectMethod dynamicaly,可以执行以下操作:

//你说类别来自URL,所以在page-load方法中

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            // Get your QueryString variable
            if (Request["YourVariable"] != null)
            {
             string yourVariable = Request["YourVariable"].ToString();

              if (yourVariable == "CategoryX") {

                   ObjectDataSource1.SelectMethod = "SelectMethodFromCategoryX";

                   // and if you need to set SelectParameters to your ObjectDataSource
                   ObjectDataSource1.SelectParameters["pYourParameterNameForCategoryX"].DefaultValue = this.txtTest.Text;
              }

            }
        }
    }
