這是我的.cs代碼：

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

這是標(biāo)記,

<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:TemplateField>

                 <%-- <asp:TemplateField HeaderText="Header 2">

                        </ItemTemplate>
                    </asp:TemplateField>--%>
                    <asp:TemplateField HeaderText="Data Type">

                        </ItemTemplate>
                        <FooterStyle HorizontalAlign="Right" />
                        <FooterTemplate>
                        <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" OnClick="ButtonAdd_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>

請(qǐng)認(rèn)真我.我做了這么多..但仍然沒有刪除行…

 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();
       }

解決方法:

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();
}
