C#代码总结04---通过创建临时表DataTable进行临时编辑删除
<script type="text/javascript">
//删除
function Delete(hdGuid) {
$("#hdGuid").val(hdGuid);
$("#btnDel").click();
}
</script>
<body>
<input />
<asp:ImageButton ImageUrl="" runat="server" OnClientClick="return confirm('确认删除该入库申请?');"
OnClick="btnDel_Click" CssClass="hidden" />
。。。。。。
<cc:PagingGridView Width="100%" runat="server" AutoGenerateColumns="False"
PageSize="20" OnBindDataSource="GridViewData_BindDataSource">
<EmptyDataTemplate>
无相关数据
</EmptyDataTemplate>
<Columns>
<asp:TemplateField HeaderText="操作">
<HeaderStyle Width="5%" />
<ItemStyle Width="5%" />
<ItemTemplate>
<a href="#" onclick="Delete('<%# Container.DataItemIndex%>')" class="aCss addreturn">
<img src="../images/DGBtn/sc.gif" alt="删除" />
</a>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<RowStyle CssClass="td1" />
<HeaderStyle CssClass="td_bthead" />
<PagerStyle CssClass="td0" />
<AlternatingRowStyle CssClass="td2" />
</cc:PagingGridView>
</div>
</form>
</body>
以上为前台代码????
后台代码：
/// <summary>
/// 保存临时表datatable
/// </summary>
protected DataTable dt0
{
get { return (DataTable)ViewState["dt0"]; }
set { ViewState["dt0"] = value; }
} protected void btnDel_Click(object sender, ImageClickEventArgs e)
{
int cfs = Convert.ToInt32(cftsTB.Text);
if (cfs > 1)
{
dt0.Rows.RemoveAt(Convert.ToInt32(hdGuid.Value));
PageDataList.BindGridView(GridViewData, dt0);
cftsTB.Text = string.Format("{0}", cfs - 1);
}
else
{
PageHelper.MessageBox(this, "拆分数目需要大于1！");
}
}问题在于，①创建一个全局的临时表变量 dt0 ，用于调用和修改；②使用datatable的属性方法来进行操作、如
PageDataList.BindGridView(GridViewData, dt0);
dt0.Rows.RemoveAt(Convert.ToInt32(hdGuid.Value));
删除是根据 页面序号(hdGuid.Value)来进行操作的
附上通常创建临时表的代码：
public void creatCfdt(decimal cfNum)
{
string result = null;
ZcKcbEntity kcb = new ZcKcbAction().GetInfo(guid);
DataTable data = new DataTable();
data.Columns.Add(new DataColumn("guid", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("zcmc", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("czcode", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("dj", System.Type.GetType("System.Decimal")));
data.Columns.Add(new DataColumn("je", System.Type.GetType("System.Decimal")));
data.Columns.Add(new DataColumn("syr", Type.GetType("System.String")));
data.Columns.Add(new DataColumn("sybm", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("syfx", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("cfdd", System.Type.GetType("System.String")));
data.Columns.Add(new DataColumn("djsj", System.Type.GetType("System.DateTime")));
data.Columns.Add(new DataColumn("sl", Type.GetType("System.Decimal")));
DataRow row2 = data.NewRow();
row2["guid"] = kcb.guid;
row2["zcmc"] = kcb.zcmc;
row2["czcode"] = kcb.czcode;
row2["dj"] = kcb.dj;
row2["je"] = kcb.je;
row2["syr"] = kcb.syr;
row2["sybm"] = kcb.sybm;
row2["syfx"] = kcb.syfx;
row2["cfdd"] = kcb.cfdd;
row2["djsj"] = kcb.djsj;
row2["sl"] = kcb.sl - cfNum + 1;
data.Rows.Add(row2);
dt0 = data;
if (data != null)
{
//绑定数据
if (!PageDataList.BindGridView(GridViewData, data))
{
result = "绑定列表失败!";
}
}
else
{
result = "获取数据失败!";
}
//返回结果
PageHelper.MessageBox2(this, result);
