c# – 如何使用rowdeleting事件删除gridview中的行？

这是我的.cs代码：

protected void Gridview1_RowDeleting(object sender, GridViewDeleteEventArgs e){ Gridview1.DeleteRow(e.RowIndex); Gridview1.DataBind();}

这是标记,

<asp:gridview ID="Gridview1" runat="server" ShowFooter="true"                                                 AutoGenerateColumns="false" OnRowDeleting="Gridview1_RowDeleting">                    <Columns>                    <asp:BoundField DataField="RowNumber" HeaderText="Row Number" />                    <asp:TemplateField HeaderText="Column Name">                        <ItemTemplate>                            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>                        </ItemTemplate>                    </asp:TemplateField>                 <%-- <asp:TemplateField HeaderText="Header 2">                        <ItemTemplate>                            <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>                        </ItemTemplate>                    </asp:TemplateField>--%>                    <asp:TemplateField HeaderText="Data Type">                        <ItemTemplate>                              <asp:DropDownList ID="ddldatatype" runat="server">                              <asp:ListItem>varchar</asp:ListItem>                              <asp:ListItem>int</asp:ListItem>                              <asp:ListItem>numeric</asp:ListItem>                              <asp:ListItem>uniqueidentifier</asp:ListItem>                              <asp:ListItem>char</asp:ListItem>                              </asp:DropDownList>                        </ItemTemplate>                        <FooterStyle HorizontalAlign="Right" />                        <FooterTemplate>                        <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" OnClick="ButtonAdd_Click"/>                         <asp:Button ID="ButtonDel" runat="server" Text="Delete Row" OnClick="ButtonDel_Click" />                         <input type="hidden" runat="server" value="0" id="hiddencount" />                        </FooterTemplate>                    </asp:TemplateField>                    <asp:TemplateField>                        <ItemTemplate>                            <asp:LinkButton ID="lnkdelete" runat="server" CommandName="Delete" >Delete</asp:LinkButton>                        </ItemTemplate>                    </asp:TemplateField>                    </Columns>            </asp:gridview>

请认真我.我做了这么多..但仍然没有删除行…

 protected void Gridview1_RowDeleting(object sender, GridViewDeleteEventArgs e)         {             //Gridview1.DeleteRow((int)Gridview1.DataKeys[e.RowIndex].Value);             //Gridview1.DeleteRow(e.RowIndex);             //Gridview1.DataBind();             foreach(DataRow dr in dt.Rows)             {                 dt.Rows.Remove(dr);                 dt.Rows[e.RowIndex].Delete();             }             Gridview1.DeleteRow(e.RowIndex);            // dt = (DataTable)Gridview1.DataSource;             Gridview1.DataSource = dt;             Gridview1.DataBind();       }

解决方法:

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e){    GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];    SqlCommand cmd = new SqlCommand("Delete From userTable (userName,age,birthPLace)");    GridView1.DataBind();}
