想要啓用圖像按鈕基於Gridview字段中的值

Question

在Gridview中，我正在使用圖像按鈕，希望根據字段中的值啓用。我的部分代碼是..

<asp:ImageButton ID="btn_delete" **Enabled='<%# Eval("fld_status").ToString()=="1" ? "False" : "True" %>**' runat="server" ToolTip="Delete" OnClientClick="return confirm('Important Alert : Do you delete this item ?')" CommandName="del" CommandArgument='<%#Bind("fld_id") %>' />

通過 RowDataBound

（我喜歡）：

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     DataRowView row = (DataRowView)e.Row.DataItem; 
     int status = (int)row["fld_status"]; 
     Button btn_delete = (Button) e.Row.FindControl("btn_delete"); 
     btn_delete.Enabled = status != 1; 
    } 
} 

從ASPX：

<asp:ImageButton ID="btn_delete" runat="server" 
    Enabled='<%# ((int)Eval("fld_status") !=1) ? true : false %>' 
    ToolTip="Delete" OnClientClick="return confirm('Important Alert : Do you delete this item ?')" CommandName="del" CommandArgument='<%#Bind("fld_id") %>' 
/>
