在您gvData _OnRowDataBound，檢查病情，並做出相應的按鈕Visible屬性設置爲false每一行。

  protected void gvData_OnRowDataBound(object sender, GridViewRowEventArgs e) 
      { 
       LinkButton lbClose = (LinkButton)e.Row.Cells[5].FindControl("lbClose"); 
       LinkButton lbEdit = (LinkButton)e.Row.Cells[5].FindControl("lbEdit"); 
       LinkButton lbDelete = (LinkButton)e.Row.Cells[5].FindControl("lbDelete"); 
       LinkButton lbWrite = (LinkButton)e.Row.Cells[5].FindControl("lbWrite"); 
       LinkButton lbRT = (LinkButton)e.Row.Cells[5].FindControl("lbRT"); 

       if(e.Row.Cells[1].Text=="Dessert") 
       { 
        lbClose.Visible = false; 
        lbEdit.Visible = false; 
        lbDelete.Visible = false; 
       } 
       else 
       { 
        lbWrite.Visible = false; 
        lbRT.Visible = false; 
       } 
      } 

Answer 2

在過去，我做了一個代碼隱藏方法來評估和返回一個布爾值。

protected bool IsTransTypeDessert(string transType) 
{ 
    return transType.ToLower() == "dessert"; 
} 

然後在標記，調用該方法如下所示：

我不記得

<asp:LinkButton ID="lbWrite" runat="server" CausesValidation="False" CommandName="WriteClicked" OnClick="Write_Click" 
Visible='<%# IsTransTypeDessert(Eval("TRANSTYPE") != null ? Eval("TRANSTYPE").ToString() : "") %>'>Write</asp:LinkButton> 

的一件事是，如果IsTransTypeDessert需要返回「真」或「假」或字符串表示如果布爾將工作。測試將決定它。
