这里是删除按钮的代码。



在aspx文件中我们添加代码：

 <   asp：GridView     ID   =  GridView1    runat   = 服务器    AutoGenerateColumns   = 错误    CellPadding   =  4    EnableModelValidation   =  True  
   
                          字体名称  =  Tahoma   字体大小  =  8pt    ForeColor   = ＃333333    宽度  = < span class =code-keyword> 100％    OnRowCommand   =  GridView1_RowCommand >  
 <   AlternatingRowStyle     BackColor   = 白色    ForeColor   = ＃284775    /  >  
 <  列 >  
 <   asp：BoundField     DataField   =  No    HeaderText   = 否。 >  
 <   HeaderStyle    宽度  =  100px    /  >  
 <   ItemStyle    宽度  =  100px     /  >  
 <   / asp：BoundField  >  
 <   asp：TemplateField     HeaderText   = 删除 >  
 <   HeaderStyle    宽度  =  50px    /  >  
 <   ItemStyle    宽度  =  50px    /   >  
 <   ItemTemplate  >  
 <   asp：ImageButton     runat   = 服务器    CommandName   =  delete    ImageUrl   = 〜/ images / delete.png    CommandArgument   ='  <％ #Eval（  ID）％> '    /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   asp：BoundField     DataField   =  CustName    HeaderText   = 名称    /  >  
 <  < span class =code-leadattribute> / Columns  >  
 <   EditRowStyle     BackColor   = ＃999999    /  >  
 <   FooterStyle     BackColor   = ＃5D7B9D   字体粗体  = 真    ForeColor   = 白色    /  >  
 <   HeaderStyle     BackColor   = ＃5D7B9D   字体粗体  =  True    ForeColor   = 白色    /  >  
 <   PagerStyle     BackColor   = ＃284775   < span class =code-attribute> ForeColor   = 白色    Horizo​​ntalAlign   = 中心    /  >  
 <   RowStyle     BackColor   = ＃F7F6F3    ForeColor   = ＃333333    /  >  
 <   SelectedRowStyle     BackColor   = ＃E2DED6    Font-Bold   =  True    ForeColor   = ＃333333     /  >  
 <   / asp：GridView  < span class =code-keyword>>  

在代码中我们添加以下代码：

 受保护  void  GridView1_RowCommand（ object  sender，GridViewCommandEventArgs e）
 {
  if （e。 CommandName.Equals（  delete，StringComparison.OrdinalIgnoreCase））
 {
  //  获取所需记录的ID  
  var  rowId = Convert.ToInt32（e.CommandArgument）; 
  //   ....  
 GridView1.DataBind（）;  //  刷新数据源 
} 
} 

I am using a grid view, and inside that there's a edit button for each row, i want on button's click the values of row selected cell[1] value to store in a a label..
using asp.net c#

解决方案

Please see this link.

http://www.aspsnippets.com/Articles/Get-selected-row-in-GridView-on-Button-Click-in-ASPNet.aspx[^]

here is code for delete button.

in aspx file we add code:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" EnableModelValidation="True"

            Font-Names="Tahoma" Font-Size="8pt" ForeColor="#333333" Width="100%" OnRowCommand="GridView1_RowCommand">
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <Columns>
                <asp:BoundField DataField="No" HeaderText="No.">
                <HeaderStyle Width="100px" />
                <ItemStyle Width="100px" />
                </asp:BoundField>
                <asp:TemplateField HeaderText="Delete">
                    <HeaderStyle Width="50px" />
                    <ItemStyle Width="50px" />
                    <ItemTemplate>
                        <asp:ImageButton runat="server" CommandName="delete" ImageUrl="~/images/delete.png" CommandArgument='<%#Eval("ID")%>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="CustName" HeaderText="Name" />
            </Columns>
            <EditRowStyle BackColor="#999999" />
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
        </asp:GridView>

And in code behind we add following code:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName.Equals("delete", StringComparison.OrdinalIgnoreCase))
            {
                //get id of record that you want
                var rowId = Convert.ToInt32(e.CommandArgument);
                //....
                GridView1.DataBind();//refresh data source
            }
        }
