請詳細提供您的問題。你想禁用RadAsyncUpload控制或其他？ – 2012-02-03 05:37:03

只有我已禁用RadAsyncUpload控制頁面加載期間執行某些條件.. – 2012-02-03 06:17:31

您將在RadGrid的DataBinding/DataBound Item事件期間禁用RadAsyncUpload控件。

DataBinding/DataBound是事件當服務器控件綁定到數據源時發生。（繼承自Control。）

當你綁定一個RadGrid控件。爲前。

 protected void Page_Load(object sender,System.EventArgs e) 
     { 
      if(!IsPostBack) 
      { 
// Here I creates temporary datatable.. 
// you can generate dynamic DataTable from SQL query to fill DataSet/DataTable. 
// Here I created temp DataTable for Binding RadGrid grid control.. 
      DataTable dt = new DataTable("temp");   

      RadGrid.DataSource= dt; 
      RadGrid.DataBind(); 
      // It will event fired When you binding data source. 
      // If You have to added "RadGrid_ItemDataBound" Item bound event to the <RADGRID >... control. 
      } 
     } 
      protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e) 
      { 
       if (e.Item is GridDataItem) 
       { 
        RadAsyncUpload asyncUpload = (RadAsyncUpload) e.Item.FindControl("RadAsyncUploadControlID");  
        bool blUploadControlHide=true; 
        if(asyncUpload !=null) 
        { 
        if(blUploadControlHide) 
        { 
         asyncUpload.Enabled = false; 
         //If you can hide then write asyncUpload.Visible = false; 
        } 
        else 
        { 
         asyncUpload.Enabled = true; 
        } 
        }  
       } 
      }

參考Radgrid Events

感謝

@ user1177921當RADGrid控件綁定的項目將被解僱..你可以通過放置斷點來檢查。 – 2012-02-03 10:49:37

你可以掛接到radgrid控件的ItemDataBound事件，然後找到控制，可以通過這個鏈接。 Telerik RadGrid - databound Events.

SomeGrid_ItemDataBound(object sender, GridItemEventArgs e) 
{ 
if (e.Item is GridDataItem) 
{ 
RadAsyncUpload objUpload = (RadAsyncUpload) e.Item.FindControl("RadUpload1"); 

if(opbjUpload !=null) 
{ 
    // do some thing with Upload Obj. 
} 

} 
}
