一：修改

先来看一下效果

步骤一：先创建一个GridView 在编辑列中将此字段转换为TemplateField

View Code

<asp:GridView ID="GridUpdaMoney" runat="server"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" EmptyDataText="暂时没有数据" AutoGenerateColumns="False"
DataKeyNames="id" onrowcancelingedit="GridUpdaMoney_RowCancelingEdit"
onrowediting="GridUpdaMoney_RowEditing"
onrowupdating="GridUpdaMoney_RowUpdating">
<RowStyle ForeColor="#000066"/>
<Columns>

<asp:TemplateField HeaderText="工资申报年月份">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("C_Year") %>' onFocus="WdatePicker()"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("C_Year") %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"/>
</asp:TemplateField>
<asp:TemplateField HeaderText="标准工资">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("C_BasicMoney") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("C_BasicMoney") %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"/>
</asp:TemplateField>
<asp:TemplateField HeaderText="申请状态">
<ItemTemplate>
<asp:Label ID="status" runat="server" Text='<%# GetStatus(Eval("status").ToString()) %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"/>
</asp:TemplateField>
<asp:TemplateField HeaderText="修改" ShowHeader="False">
<EditItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True"
CommandName="Update" Text="更新"></asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False"
CommandName="Cancel" Text="取消"></asp:LinkButton>
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"
CommandName="Edit" Text="编辑"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066"/>
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"/>
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White"/>
</asp:GridView>

步骤二：添加事件RowCancelingEdit

View Code

protectedvoid GridUpdaMoney_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridUpdaMoney.EditIndex =-1;
BindGridUpdaMoney(ViewState["PersonCardNo"].ToString());
}

步骤三：添加RowUpdating事件

View Code

protectedvoid GridUpdaMoney_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int id = Convert.ToInt32(GridUpdaMoney.DataKeys[e.RowIndex].Value);
TextBox year = GridUpdaMoney.Rows[e.RowIndex].FindControl("TextBox1") as TextBox;
TextBox money = GridUpdaMoney.Rows[e.RowIndex].FindControl("TextBox2") as TextBox;
BasicMoney bm =new BasicMoney();
bm.Id = id;
bm.Year = Convert.ToDateTime(year.Text.Trim());
bm.BasicMoney1 = Convert.ToDecimal(money.Text.Trim());
int result = BasicMoney.UpdaBasicMoneyById(bm);
if (result >0)
{
JS.Alert(Page, "修改成功");
}
else
{
JS.Alert(Page, "修改失败");
}
GridUpdaMoney.EditIndex =-1;
BindGridUpdaMoney(ViewState["PersonCardNo"].ToString());
}

步骤四：添加RowEditing事件

View Code

protectedvoid GridUpdaMoney_RowEditing(object sender, GridViewEditEventArgs e)
{
GridUpdaMoney.EditIndex= e.NewEditIndex;
BindGridUpdaMoney(ViewState["PersonCardNo"].ToString());
}

二：删除（2012-2-9日修改随笔）

删除和添加效果

View Code

<asp:GridView Width="100%" ID="GridView2" runat="server" 
            AutoGenerateColumns="False" DataKeyNames="id" 
            onrowcancelingedit="GridView2_RowCancelingEdit" ShowFooter="True" 
            onrowupdating="GridView2_RowUpdating" onrowediting="GridView2_RowEditing" 
            EmptyDataText="暂时没有数据" onrowdeleting="GridView2_RowDeleting" 
           onrowcommand="GridView2_RowCommand">
            <EmptyDataRowStyle HorizontalAlign="Center" VerticalAlign="Top" />
            <Columns>
                <asp:TemplateField >
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox2" runat="server" Width="50" Text='<%# Bind("difficultName") %>'></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("difficultName") %>'></asp:Label>
                    </ItemTemplate>
                    <FooterTemplate>
                        <asp:TextBox ID="TextBox4" runat="server" Width="50"></asp:TextBox>
                    </FooterTemplate>

                    <FooterStyle HorizontalAlign="Center" VerticalAlign="Middle" />

                    <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="300px" />
                </asp:TemplateField>
                <asp:TemplateField>
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox3" runat="server" Width="50" Text='<%# Bind("waitScore") %>'></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="Label2" runat="server" Text='<%# Bind("waitScore") %>'></asp:Label>
                    </ItemTemplate>
                    <FooterTemplate>
                        <asp:TextBox ID="TextBox5" runat="server" Width="50"></asp:TextBox>
                    </FooterTemplate>

                    <FooterStyle HorizontalAlign="Center" VerticalAlign="Middle" />

                    <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="300px" />
                </asp:TemplateField>
                <asp:TemplateField ShowHeader="false" InsertVisible="False">
                <EditItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True"                                 
                 CommandName="Update" Text="更新"></asp:LinkButton>                              
                 <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False"                                  
                 CommandName="Cancel" Text="取消"></asp:LinkButton>
                </EditItemTemplate>
                <ItemTemplate>                             
                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"                                  
                CommandName="Edit" Text="编辑"></asp:LinkButton>  
<asp:LinkButton ID="LinkButton4" runat="server" CausesValidation="False" 
                        CommandName="Delete"    Text="删除"></asp:LinkButton>

                </ItemTemplate>
                <FooterTemplate>
                        <asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="True" CommandName="Insert"
                            Text="插入"></asp:LinkButton>
                    </FooterTemplate>

                    <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

删除代码：

View Code

 protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
int id = Convert.ToInt32(GridView2.DataKeys[e.RowIndex].Value);
        difficu.Delete(id);
        Bind();
    }

添加代码：（注要显示添加的行必须设置属性 ShowFooter="True" ）

View Code

protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
    {
try
        {
switch (e.CommandName)
            {
case "Insert":
                    myWeb.Model.DifficultDegree d = new myWeb.Model.DifficultDegree();
                    d.fatherId = 4;
                    d.difficultName = ((TextBox)GridView2.FooterRow.FindControl("TextBox4")).Text;
                    d.waitScore = Convert.ToInt32(((TextBox)GridView2.FooterRow.FindControl("TextBox5")).Text);
                    difficu.Add(d);
                    Bind();
break;
            }
        }
catch (Exception ex)
        { }

    }
