如何在Gridview中添加下拉字段?

How to add a dropdown field in a Gridview?

推荐答案

在这里:
访问GridView中的DropDownList [ GridView内部的DropDownList(方法1) [在ASP.NET 2.0(C#)中将DropDownList嵌套到Gridview [ ^ ]

下次，请使用Google-效果很好.此外，也要花一些时间来阐述问题.

Here you go:
Accessing a DropDownList inside a GridView[^]
DropDownList Inside GridView (Method 1) [^]
Nesting the DropDownList to Gridview in ASP.NET 2.0(C#)[^]

Next time, please use Google - it works wonder. Further, do spend some time in formulating the question too.

在GridView中创建一个ItemTemplate.并将DropDown放入您的ItemTemplate中.

如果DropDown Items是动态的，请添加数据源以绑定DropDown.

Create a ItemTemplate in GridView. And Place DropDown inside your ItemTemplate.

If DropDown Items are dynamic add datasource to bind the DropDown.

使用此代码，我认为这将为您提供完整的解决方案.

Use this code I think this will give you complete solution.

<asp:GridView id="grdSystemInfo" runat="server" Width="940px"

                       Font-Names="Verdana" Font-Size="Small" UseAccessibleHeader="False"  PageSize="5"

                       AllowPaging="True" OnPageIndexChanging="grdSystemInfo_PageIndexChanging" onrowcommand="grdSystemInfo_RowCommand"

                       >
           <PagerStyle Font-Bold="True"  />
           <HeaderStyle Font-Names="Verdana" Font-Size="Small" Font-Bold="True" BackColor="#E0E0E0"  />
           <Columns>
           <asp:BoundField DataField="DateTimes"  HeaderText="DateAccessed" />
           <asp:TemplateField HeaderText="Search By">
           <ItemTemplate>
               <asp:DropDownList ID="DropDownList2" runat="server"  OnSelectedIndexChanged="drpl2_selectedIndexChange" AutoPostBack="true">
               <asp:ListItem>Monitor Details</asp:ListItem>
               <asp:ListItem>KeyBoard Details</asp:ListItem>
               <asp:ListItem>Mouse Details</asp:ListItem>
               <asp:ListItem>Processor Details</asp:ListItem>
               <asp:ListItem>O/S Details</asp:ListItem>
               <asp:ListItem>HardDisk Details</asp:ListItem>
               </asp:DropDownList>
           </ItemTemplate>
           </asp:TemplateField>
           </Columns>
       </asp:GridView>

受保护的void drpl2_selectedIndexChange(对象发送者，EventArgs e)
{
//获取对行的引用
GridViewRow gvr =(GridViewRow)((((Control)sender).NamingContainer);
//获取此DropDownlist的引用
DropDownList ddlItem =(DropDownList)gvr.FindControl("DropDownList2");
//在这里进行处理
}

protected void drpl2_selectedIndexChange(object sender, EventArgs e)
{
// get reference to the row
GridViewRow gvr = (GridViewRow)(((Control)sender).NamingContainer);
// Get the reference of this DropDownlist
DropDownList ddlItem = (DropDownList)gvr.FindControl("DropDownList2");
//do the processing here
}
