Question

我尝试禁用/隐藏或不想在拒绝文档中显示下载选项，如此

这是我想要的

              doc id doc name file uplaoded uploaded date department   status 
 download     1    analysis  abc.docx    12-12-2013   finance        approve
              2    report fm  fm.docx    14-06-2013   finance         reject
 download     3    report ibf  ibf.docx    14-06-2013   finance        approve
              4    report ma  ma.docx    14-06-2013   finance         reject

现在在拒绝行中我不想显示下载选项，因为这是被拒绝的文件，这里是我尝试的代码

        protected void Repeater4_ItemDataBound(object sender, RepeaterItemEventArgs e)
       {

        //DataRowView theDataRowView = e.Item.DataItem as DataRowView;
        //theDataRowView.Row["Status"] == "Status";

        // Only look in data rows, ignore header and footer rows
        if (e.Item.ItemType == ListItemType.AlternatingItem ||
         e.Item.ItemType == ListItemType.Item)
         {
            // Get a data view row object so we can reference the data 
            // in the repeater by the bound field names      
            DataRowView theDataRowView = e.Item.DataItem as DataRowView;
            //theDataRowView.Row["Status"] == "Status";

            // Make sure we got the data row view before we try to use it
            if (theDataRowView != null)
            {
                // Get the value of status from the control that holds the value
                string theStatus = theDataRowView.Row["Status"].ToString();

                // Find the download link control
                LinkButton theLinkButtonDownload = e.Item.FindControl("LinkButton2")
             as LinkButton;

                if (theStatus.ToUpper() == "APPROVE")
                {
                    if (theLinkButtonDownload != null)
                    {
                        theLinkButtonDownload.Visible = true;
                    }
                }
                else
                {
                    if (theLinkButtonDownload != null)
                    {
                        theLinkButtonDownload.Visible = false;
                    }
                    }
                  }
                }


           }

这是html

我尝试我发布的代码并且它无法向我显示任何错误但它总是显示我在被拒绝的文档中可见下载并且我想在拒绝的文档下载选项不想显示

Answer 1

因为您使用ToUpper，请与大写字符串值进行比较，如下所示

Visible='<%#Convert.ToString(Eval("Status")).ToUpper() != "REJECT" %>'

在Asp.Net中下载表格中的选项
