发布时间：2020-12-15 20:05:46 所属栏目：百科来源：网络整理

导读：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" AutoGenerateCol

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();
}
