asp.net 在GridView控件上实现修改、添加、删除

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

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

步骤三：添加RowUpdating事件

View Code

protected void 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

protected void 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)
        { }

    }

完成，为了不忘记就记录一下...
