           ViewState["ds"] = ds;

           if (ds != null)

               gvconference.Visible = true;
               gvconference.DataSource = ds;
               gvconference.DataBind();

推荐答案

protected void gvconference_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       try
       {

            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string EmployeeId = Session["EmployeeId"].ToString();
                Button b = (Button)e.Row.FindControl("btnDelete");
              b.Attributes.Add("onclick", "javascript:return " +
             "confirm('Are you sure you want to delete this record " +
      DataBinder.Eval(e.Row.DataItem, "SequenceId") + "')");
                }
//***********************************
if(CheckYourConditions)// Check for the condition here
{
 b.Enabled = true;
}
else
{
 b.Enabled = false;
}

//***********************************
                            }

           }

       catch (Exception ex)
       {
           if (log.IsErrorEnabled)
           {
               log.Error(ex.Message);
           }
       }

   }

在页面加载检查中，如果用户被授权，则是否被授权，

启用您的删除按钮否则会被禁用

in Page Load check User is authorized or not if he is authorized then

enabled Your delete button other wise make it disabled

所有取决于您如何实现授权.
在您的Page_Load中编写如下内容:

All depends how you have implemented an authorization.
Write in your Page_Load something like this:

//...
btnDelete.Enabled=IsAuthorized;
//...

并根据您的授权实施IsAuthorized属性.此属性对配置UI的其余部分很有用.

And implement IsAuthorized property depending your authorization. This property will be useful to configure the rest of UI.
