如何仅在gridview中显示选定的列，其中gridview列元素在运行时创建 [英] How do I display only selected column in gridview where gridview column element is created at runtime

问题描述

我的申请代码如下所示：



public NameList [] NavisionJobList（string UserID）

{

//逻辑

//返回特定值

}



和我的aspx页面，将返回值绑定到网格的代码是：



Grid.DataSource = fetchnavisionData.NavisionJobList（Ramesh）;

Grid.DataBind（）;



在客户端，gridview的代码是：

 <   asp：GridView     ID   = 网格 < span class =code-attribute>   runat   =  server >  
 <   / asp：GridView  >  

使用这个，我按照预期将所有字段作为gridview中的列。但是我只希望选择的字段显示在网格而不是所有字段中。我怎么能这样做。???

在客户端，我添加了绑定字段，但这导致重复网格中的列< columns> 。帮我解决问题..

解决方案

  protected   void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
  //  此处应用您的条件 
  if （Request.QueryString [  name] ==   all）
 e.Row.Cells [< index_of_cell>]。Visible =  true ; 
  else  
 e.Row.Cells [< index_of_cell>]。Visible =  false ; 
} 
} 

我添加了autogeneratedcolumn并将其设置为true并手动添加了列字段和属性，它工作，。，

The code of my application is shown below:

public NameList[] NavisionJobList(string UserID)
{
//logic
// return certain value
}

and in my aspx page, the code to bind the returned value to grid is:

Grid.DataSource = fetchnavisionData.NavisionJobList("Ramesh");
Grid.DataBind();

In client side the code of gridview is:

<asp:GridView ID="Grid" runat="server">
          </asp:GridView>

Using this, i got all the fields as a column in gridview as expected. However i only wanted selected fields to be displayed in grid and not all fields.. How can I do it.???
in client side, I had added bound fields but that resulted to repetition of columns in grid<columns> . help me solve the issue..

解决方案

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //here apply your condition
        if(Request.QueryString["name"] == "all")
        e.Row.Cells[<index_of_cell>].Visible = true;
        else
        e.Row.Cells[<index_of_cell>].Visible = false;
    }
}

i added autogeneratedcolumn and set it to true and added column field and properties manually and it worked,.,
