获取GridView中的ID值

Question

有一个GridView代码如下：
<asp:GridView ID="GridView_WarningList" runat="server"  CssClass="warninglist" 
        AllowSorting="True" AutoGenerateColumns="False"   DataKeyNames="ID" 
        PageSize="18" AllowPaging="true" 
        onpageindexchanging="GridView_WarningList_PageIndexChanging">
        <Columns>
       
        <asp:BoundField  DataField="ID"  HeaderText="编号"/>
        <asp:BoundField  DataField="Title"  HeaderText="信息标题" />
        <asp:BoundField  DataField="Time" HeaderText="时间" DataFormatString="{0:yyyy-mm-dd}" />
         <asp:TemplateField HeaderText="操作" >
        <ItemTemplate>
            <asp:Button ID="check_btn" runat="server" Text="查看"  CssClass="admin_control"/>
            <asp:Button ID="alter_btn"
                runat="server" Text="修改" CssClass="admin_control"   OnClick="Alter_Click" />  
问题：如何在“修改按钮”的“OnClick”事件“Alter_Click”中获取该行对应的“ID”值？
后台方法：
protected void Alter_Click (object sender,EventArgs e)
        { 
           
        }

            <asp:CheckBox ID="select_box" runat="server"  CssClass="admin_control"/></ItemTemplate>
        </asp:TemplateField>
        </Columns>
        <SelectedRowStyle  BackColor="#eeeef6" />
        <PagerStyle  BackColor="#eeeef6" Font-Bold="true" Font-Underline="true" HorizontalAlign="Left"  />
        <HeaderStyle  CssClass="warninglist_header"/>
        <FooterStyle  CssClass="warninglist_footer"/>
</asp:GridView>

Answer 1

设置ommandArgument  
或GridViewRow gvr = (sender as Button).NamingContainer as GridViewRow;   
TextBox txt=gvr.FindControl("txt") as TextBox;

Answer 2

可以绑定的
后台用rowcommand事件

Answer 3

是不是这个思路？？？

Answer 5

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" />
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    protected void Button1_Click(object sender, EventArgs e)
    {
        int index = ((GridViewRow)(sender as Button).Parent.Parent).RowIndex;
        int id = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text);
        Response.Write(id.ToString());
    }

Answer 6

protected void Alter_Click (object sender,EventArgs e)
{ 
  Button Ig = (Button)sender;
  GridViewRow gv = (GridViewRow)Ig.Parent.Parent;
  string strID= GridView_WarningList.DataKeys[gv.RowIndex].Values[0];
}

Answer 7

gv.RowIndex 就是你点击行的索引

Answer 8

还有个更加简单的方法 你在按钮里面绑定“ID”值就OK了
asp:Button ID="alter_btn"
runat="server" Text="修改" CssClass="admin_control" OnClick="Alter_Click"  CommandName="SelectData" CommandArgument='<%#Eval("ID") %>' />   
在后台激发RowCommand事件就能获取到
 if (e.CommandName == "SelectData")
 { 
string strDataKey = e.CommandArgument.ToString();
}

Answer 9

楼上已经说了一些方法，还可以通过
对<asp:Button ID="alter_btn"
runat="server" Text="修改"  aaa='<%# Eval("ID")%>' CssClass="admin_control" OnClick="Alter_Click" />  后台将E转换为BUTTON 然后 button.Attributes["aaa"] 来获得，貌似是这样，不知道写的对不对，你试试？

Answer 10

以前我也经常遇到这样的问题，在GRIDVIEW里获得比如 下拉列表框 然后要获得ID，按钮还强点，可以使用commandArgument   那些根据name判断获取。前几天使用Attributes获得，效果是相当好啊，哈哈

Answer 11

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" />
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" aaa='<%# Eval("ID")%>'/>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
protected void Button1_Click(object sender, EventArgs e)
    {
Button b=sender as Button;
        int index = Convert.ToInt32(b.Attributes["aaa"].ToString());
        Response.Write(id.ToString());
    }

Answer 12

13楼的最简单了，也最常用，不会出错,用CommanArgument绑定
