如何在asp.net中将下拉列表添加到Gridview中 [英] How to add dropdownlist into Gridview in asp.net

问题描述

我有一个网格控件，我想添加下拉列表框.下拉菜单的目的是在网格中显示页面，如果我选择 1 gridview page1 或 2 表示网格中的第二页等，当我要打印出来时，该下拉菜单不应该查看

I've a grid control, in that I want to add dropdownlist box. The pupose of the dropdown is to show the page in in the grid, If I select 1 the gridview page1 or 2 means 2nd page in the grid etc, that drop down should not view while I'm going to take print out

我当前的代码:

protected void PageDropDownList_SelectedIndexChanged(Object sender, EventArgs e) 
{ 
    GridViewRow pagerRow = gvDetails.BottomPagerRow; 
    DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList"); 
    gvDetails.PageIndex = pageList.SelectedIndex; 
}

推荐答案

要向网格单元添加下拉菜单，您应该使用 ItemTemplates，尤其是编辑模式 ItemTemplate，请参阅此处获取完整示例: 演练:编辑时显示下拉列表在 GridView Web 服务器控件中

to add a drop down to a grid cell you should use ItemTemplates and especially the edit mode ItemTemplate, see here for a full example: Walkthrough: Displaying a Drop-Down List While Editing in the GridView Web Server Control

无论如何，我不确定您对它的使用情况，如果您需要从一个页面移动到另一个页面，您应该使用页脚/分页控件，或者您可以在 GridView 外有一个下拉菜单，您可以在其中选择页面，然后您进行更改Grid 的 Current PageIndex 并再次调用 DataBind.

I am anyway not sure about your usage of it, if you need to move from one page to another you should use the Footer/Pager control or you can have a drop down outside the GridView where you select the page then you change the Current PageIndex of the Grid and call DataBind again.
