如何在asp.net中动态添加gridview c＃ [英] How to dynamically add gridview in asp.net c#

问题描述

你好，我必须在asp.net中动态添加多个gridview。没有gridview是基于选择而生成的。
先进的感谢

解决方案

如果我没有理解错误标题，动态添加多个网格视图意味着要添加GridView是ASP.NET C＃中的一个类，我们可以创建它的对象并设置其属性，就像其他类对象一样如下所示：

  GridView objGV = new GridView（）; 
 objGV .AutoGenerateColumns = false; 
  

可以从代码中添加像BoundField和TemplateField这样不同类型的列如下所示：

  BoundField field = new BoundField（）; 
 field.HeaderText =列标题; 
 field.DataField = Value; 
 objGV .Columns.Add（field）; 
  

最后可以在任何容器控件（如面板）下的.aspx中添加此网格视图对象。

  PanelId.Controls.Add（objGV）; 
  

要添加多个网格实例，只需循环上面的代码即可：

  for（int i = 0; i< yourConditionCount; i ++）
 {
 GridView objGV = new GridView（）; 
 objGV.ID =GV+ i; //每个网格视图的ID必须是唯一的
 
 //您的代码逻辑为网格视图设置属性和事件
 
 PanelId.Controls.Add（objGV）; 
} 
  

希望我能正确理解您的要求，我的解释对您有所帮助。 / p>

Hello guys i have to dynamically add multiple gridview in asp.net. There are no of gridview are genereated on the basis of selection. Thanks in advanced

解决方案

If I have not understood wrong from title that add multiple grid view dynamically means want to add grid view from code behind at run time.

As GridView is a class in ASP.NET C# and we can create object of it and set its properties just like other class object like follows:

GridView objGV = new GridView();
objGV .AutoGenerateColumns = false;

and can add columns of different type like BoundField and TemplateField from code Like follows:

BoundField field = new BoundField();
field.HeaderText = "Column Header";
field.DataField = Value;
objGV .Columns.Add(field);

and finally can add this grid view object on .aspx under any container control like panel.

PanelId.Controls.Add(objGV );

For adding multiple grid instance just iterate above code in loop like:

for(int i=0;i<yourConditionCount;i++)
{
    GridView objGV = new GridView();
     objGV.ID="GV"+i;   // ID of each grid view must be unique

    // your code logic to set properties and events for grid view

   PanelId.Controls.Add(objGV );
} 

Hope I understood your requirement correctly and my explanation will be helpful for you.
