[qzyuanmu]

GridView2.DeleteRow(e.Row.RowIndex);

我用上面的语句，貌似不行，求解

后台代码：

using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

public partial class _Default : System.Web.UI.Page
{

SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(local);Database=数据库名;Uid=帐号;Pwd=密码";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
bind();
}

//删除
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string sqlstr = "delete from 表 where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
sqlcon = new SqlConnection(strCon);
sqlcom = new SqlCommand(sqlstr,sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
bind();
}

//更新
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
sqlcon = new SqlConnection(strCon);
string sqlstr = "update 表 set 字段1='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='"

//取消

//绑定

DeleteRow只是从数据源中删除该行数据，但是数据库中还是有的

[loveheronly]

前台
<asp:TemplateField HeaderText="删除">
<EditItemTemplate>
<asp:Button ID="btnExit" runat="server" Text="删除" />
</EditItemTemplate>
<ItemTemplate>
<asp:Button ID="btnExit" CommandName="cmdExit" CommandArgument='<%# Bind("Fixnumber")%>' runat="server" Text="删除" />
</ItemTemplate>
</asp:TemplateField>

后台写
protected void gvResource_RowCommand(object sender, GridViewCommandEventArgs e)
{
string name = e.CommandName;
if (name == "cmdExit")
{
// 执行删除的代码
}

}

   <asp:ImageButton ID="btnDelete" runat="server" ImageUrl="images/common/cartdelete.gif"
                                CommandArgument='<%#Eval("id") %>' CommandName="deletePro" />

 protected void dlFavorite_ItemCommand(object source, DataListCommandEventArgs e)
    {
//删除 操作
        if (e.CommandName == "deletePro")
        {
            FavoriteManage.deleteFavorite(Convert.ToInt32(e.CommandArgument));//删除方法
            BindFavoriteList(); //重新绑定
        }
    }
