一般来讲SharePoint的表单有三种方式
1. Infopath表单的对应特定的列表（直接在列表中可以自定义列表，只适用特定列表）
2. 复杂的表单，如需要重复表，且重复表的数据需用来统计
3. Infopath: 新建一个Infopath，然后通过发布，激活，适应多个列表。
下面是一个重复表的开发实例，如下图所示：
下面是开发这种表单的常用代码：
前台代码：
<div style="padding-top: 10px;">
<asp:GridView ID="GridView1" AutoGenerateColumns="False" HeaderStyle-CssClass="GridHeader"
runat="server" RowStyle-CssClass="GridRow" Width="100%" onrowdatabound="GridView1_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="请假类型">
<ItemTemplate>
<asp:Label ID="lbID" runat="server" Visible="false" Text=‘<%# Eval("ID")%>‘></asp:Label>
<asp:CheckBox ID="CheckBox1" Visible="false" runat="server" Checked=‘<%#Eval("New") %>‘/>
<asp:DropDownList ID="ddlQjlx" runat="server">
<asp:ListItem>病假</asp:ListItem>
<asp:ListItem>事假</asp:ListItem>
<asp:ListItem>年假</asp:ListItem>
<asp:ListItem>去年年假</asp:ListItem>
<asp:ListItem>调休假</asp:ListItem>
<asp:ListItem>去年调休假</asp:ListItem>
<asp:ListItem>婚假</asp:ListItem>
<asp:ListItem>丧假</asp:ListItem>
<asp:ListItem>产假</asp:ListItem>
<asp:ListItem>陪产假</asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center"/>
</asp:TemplateField>
<asp:TemplateField HeaderText="开始时间">
<ItemTemplate>
<SharePoint:DateTimeControl ShowWeekNumber="true" HoursMode24="true" DateOnly="true"
ID="dtStartTime" runat="server"></SharePoint:DateTimeControl>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" Width="120" />
<HeaderStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="结束时间">
<ItemTemplate>
<SharePoint:DateTimeControl ShowWeekNumber="true" HoursMode24="true" DateOnly="true"
ID="dtEndTime" runat="server"></SharePoint:DateTimeControl>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" Width="120" />
<HeaderStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="备注">
<ItemTemplate>
<asp:TextBox ID="txtDemo" runat="server" Width="100%" Text=‘<%#Eval("Demo") %>‘></asp:TextBox>
</ItemTemplate>
<ItemStyle HorizontalAlign="Left" />
<HeaderStyle HorizontalAlign="Center" Width="100%"/>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="btnDelete" Text="删除" CssClass="btn" runat="server" OnClientClick="return confirm(‘是否要删除？‘);"
OnClick="btnDelete_Click" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="100" />
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
<div style="padding-bottom: 6px; text-align:left; display:block; width:100%; padding-top:6px;">
<asp:Button ID="btnAdd" runat="server" Text="增加" CssClass="btn1" OnClick="btnAdd_Click"/></div>
会用到的后台代码：
PageLoad最重要的业务逻辑
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string sID = Request["ID"];
if (!string.IsNullOrEmpty(Request["action"]) && Request["action"].ToString().Equals("select"))
{
//这是视图，IFrame模式
txtBumen.Enabled = false;
txtZhiwei.Enabled = false;
btnAdd.Visible = false;
btnClose.Visible = false;
btnSave.Visible = false;
//Response.Write("false");
}
if (string.IsNullOrEmpty(sID))
{
//新建模式
ViewState["Title"] = GetSequenceCode("QJ");
//Response.Write(ViewState["Title"].ToString());
this.txtXingmin.Text = SPContext.Current.Web.CurrentUser.Name;
//从人员信息列表去当前用户数据
SPListItem item = GetSingleItemFromPeopleInfo(SPContext.Current.Web.CurrentUser.LoginName);
if (item != null)
{
txtBumen.Text = ConvertObject(item["类别/部门"]);
txtZhiwei.Text = ConvertObject(item["职位"]);
}
LoadData();
}
else
{
//编辑模式
ViewState["ID"] = sID;
//读取数据
BindExistngData(sID);
}
LoadCalculateData();
}
}
PageLoad首次加载需绑定一行数据，当New字段为True时，表示其为新的数据，如果为fasle时，当点击删除的时候需把列表的数据也一齐删掉
//初始化DataTable结构
private DataTable InitializeDataTableStructure()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID", typeof(string));
dt.Columns.Add("Type", typeof(string));
dt.Columns.Add("BeginTime", typeof(DateTime));
dt.Columns.Add("EndTime", typeof(DateTime));
dt.Columns.Add("Demo", typeof(string));
dt.Columns.Add("New", typeof(bool));
return dt;
}
//新建数据初始化数据，绑带GridView一行空的数据
private void LoadData()
{
DataTable dt = InitializeDataTableStructure();
DataRow dr = dt.NewRow();
dr["ID"] = 1;
dr["New"] = true;
dt.Rows.Add(dr);
ViewState["_DT"] = dt;
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
遍历GridView行生成DataTable
//遍历GridView填写的数据
protected DataTable GetDataSource()
{
DataTable dt = ((DataTable)ViewState["_DT"]).Clone();
GridViewRowCollection Rows = this.GridView1.Rows;
if (Rows != null && Rows.Count > 0)
{
foreach (GridViewRow gvr in Rows)
{
Label lbID = gvr.FindControl("lbID") as Label;
CheckBox cbNew = gvr.FindControl("CheckBox1") as CheckBox;
DropDownList ddlQjlx = gvr.FindControl("ddlQjlx") as DropDownList;
DateTimeControl dtBeginTime = gvr.FindControl("dtStartTime") as DateTimeControl;
DateTimeControl dtEndTIme = gvr.FindControl("dtEndTime") as DateTimeControl;
TextBox txtDemo = gvr.FindControl("txtDemo") as TextBox;
DataRow dr = dt.NewRow();
dr["ID"] = lbID.Text;
dr["New"] = cbNew.Checked;
dr["Type"] = ddlQjlx.SelectedValue;
if (!dtBeginTime.IsDateEmpty)
{
dr["BeginTime"] = dtBeginTime.SelectedDate;
}
if (!dtEndTIme.IsDateEmpty)
{
dr["EndTime"] = dtEndTIme.SelectedDate;
}
dr["Demo"] = txtDemo.Text;
dt.Rows.Add(dr);
}
}
ViewState["_DT"] = dt;
return dt;
}
GridView可删除的功能
//删除GridView选中行的数据
protected void btnDelete_Click(object sender, EventArgs e)
{
Label LabelID = ((Label)((sender as Button).Parent.Parent as GridViewRow).FindControl("lbID"));
DataTable dt = GetDataSource();
DataRow[] drs = dt.Select("ID=‘" + LabelID.Text + "‘");
bool bIsNew = Convert.ToBoolean(drs[0]["New"].ToString());
dt.Rows.Remove(drs[0]);
if (!bIsNew)
{
//不是新的数据，把请假单次表的数据也要删掉
DeleteItemFromCiBiaoByID(LabelID.Text);
}
if (dt == null || dt.Rows.Count == 0)
{
LoadData();
dt = (DataTable)ViewState["_DT"];
}
ViewState["_DT"] = dt;
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
GridView行数据绑定代码
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataTable dt = (DataTable)ViewState["_DT"];
//Response.Write(bv.ToString());
if (e.Row.RowType == DataControlRowType.DataRow)
{
// if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
Label lbID = (Label)e.Row.FindControl("lbID");
DropDownList ddlQjlx = e.Row.FindControl("ddlQjlx") as DropDownList;
ddlQjlx.Enabled = btnSave.Visible;
DateTimeControl dtBeginTime = e.Row.FindControl("dtStartTime") as DateTimeControl;
dtBeginTime.Enabled = btnSave.Visible;
DateTimeControl dtEndTime = e.Row.FindControl("dtEndTime") as DateTimeControl;
dtEndTime.Enabled = btnSave.Visible;
TextBox txtDemo = e.Row.FindControl("txtDemo") as TextBox;
txtDemo.Enabled = btnSave.Visible;
Button btnDelete = e.Row.FindControl("btnDelete") as Button;
btnDelete.Visible = btnSave.Visible;
//btnDelete.Visible = bv;
DataRow[] drs = dt.Select("ID=‘" + lbID.Text + "‘");
if (!string.IsNullOrEmpty(ConvertObject(drs[0]["BeginTime"])))
{
dtBeginTime.SelectedDate = Convert.ToDateTime(drs[0]["BeginTime"].ToString());
}
if (!string.IsNullOrEmpty(ConvertObject(drs[0]["EndTime"])))
{
dtEndTime.SelectedDate = Convert.ToDateTime(drs[0]["EndTime"].ToString());
}
if (!string.IsNullOrEmpty(ConvertObject(drs[0]["Type"])))
{
ddlQjlx.SelectedValue = ConvertObject(drs[0]["Type"]);
}
}
}
保存按钮代码：
SPWeb web = SPContext.Current.Web;
SPList mainlist = web.Lists["请假单主表"];
SPList cilist = web.Lists["请假单次表"];
web.AllowUnsafeUpdates = true;
string sMainItemID = string.Empty;
if (ViewState["ID"] != null)
{
//旧的数据，要修改
string sID = ViewState["ID"].ToString();
SPListItem item = mainlist.GetItemById(Convert.ToInt32(sID));
item["姓名"] = txtXingmin.Text.Trim();
item["部门"] = txtBumen.Text.Trim();
item["职位"] = txtZhiwei.Text.Trim();
item.SystemUpdate();
sMainItemID = item.ID.ToString();
}
else
{
SPListItem mainNewItem = mainlist.Items.Add();
mainNewItem["Title"] = ViewState["Title"].ToString();
mainNewItem["LoginName"] = SPContext.Current.Web.CurrentUser.LoginName;
mainNewItem["姓名"] = txtXingmin.Text.Trim();
mainNewItem["部门"] = txtBumen.Text.Trim();
mainNewItem["职位"] = txtZhiwei.Text.Trim();
mainNewItem.Update();
sMainItemID = mainNewItem.ID.ToString();
}
if (dt != null & dt.Rows.Count > 0)
{
foreach (DataRow rdr in dt.Rows)
{
if (Convert.ToBoolean(rdr["New"].ToString()))
{
SPListItem oNewItem = cilist.Items.Add();
oNewItem["请假单类型"] = ConvertObject(rdr["Type"]);
oNewItem["开始时间"] = Convert.ToDateTime(rdr["BeginTime"].ToString()).ToString("yyyy-MM-dd");
oNewItem["结束时间"] = Convert.ToDateTime(rdr["EndTIme"].ToString()).ToString("yyyy-MM-dd");
oNewItem["备注"] = ConvertObject(rdr["Demo"]);
oNewItem["ParentID"] = sMainItemID;
oNewItem.Update();
}
else
{
SPListItem oCurrentItem = cilist.GetItemById(Convert.ToInt32(rdr["ID"].ToString()));
oCurrentItem["请假单类型"] = ConvertObject(rdr["Type"]);
oCurrentItem["开始时间"] = Convert.ToDateTime(rdr["BeginTime"].ToString()).ToString("yyyy-MM-dd");
oCurrentItem["结束时间"] = Convert.ToDateTime(rdr["EndTIme"].ToString()).ToString("yyyy-MM-dd");
oCurrentItem["备注"] = ConvertObject(rdr["Demo"]);
oCurrentItem.SystemUpdate();
}
}
}
