如何根据收到的Session隐藏GridView中的列 [英] How to hide a column in GridView according to recieved Session

问题描述

我已经使用BoundField属性填充了网格视图，之后我可以使用CSS类隐藏列，如下面的代码：

I have populated the grid view with BoundField property and after that I can hide a column with CSS class like following code:

<asp:BoundField DataField ="FieldNamde" HeaderText="FieldName" HeaderStyle-CssClass="hidden" ItemStyle-CssClass="hidden">

隐藏的CSS类设置如下

The CSS Class hidden is set as following

.hidden
{
display:none;
}

同样填充相同的网格视图我想要根据会话状态隐藏另一列，例如：

Also to populate the same grid view I want to hide another column according to session state for example:

if ((Session["SessionName"] != null ? (string)Session["SessionName"] : "") == "SomeText")

更确切地说，我想展示或根据Session隐藏列，如果SessionName是SomeText显示列，如果SessionName是OtherText我想隐藏列。

提前感谢您的回复。

干杯。

To be more precisely, I want to show or hide a column according to the Session and if SessionName is SomeText to show a column, if SessionName is OtherText I want to hide a column.
Thank you in advance for your reply.
Cheers.

推荐答案

我找到了一个解决方案，如果其他人遇到同样的问题，只需转到网格视图并选择事件RowCreated，然后写入代码如下：

I found a solution and in case that someone else has the same problem just go to grid view and select the event RowCreated and after that write the code as following:

protected void gvGridView_RowCreated(object sender, GridViewRowEventArgs e)
       {
             /// Session name
           if ((Session["SessionName"] != null ? (string)Session["SessionName"] : "") == "SomeText")
           {
                  /// Column that has DataField
                   if (e.Row.RowType == DataControlRowType.DataRow)
                   {
                       e.Row.Cells[0].CssClass = "hidden";
                   }
                   /// Column header
                   else if (e.Row.RowType == DataControlRowType.Header)
                   {
                       e.Row.Cells[0].CssClass = "hidden";
                   }
           }
       }

谢谢大家。
