Repeater动态绑定数据
一、我的例子：（见SJTCMS/manage/report）
（1）效果图
（2）前台代码：
<%#((DataRowView)Container.DataItem)["Colum"]%>
（3）后台代码：
///
/// 绑定RptReport
///
///
private void BindRptReport(string[] strClasses)
{
//如果没有选择栏目，则返回
if (strClasses==null || string.IsNullOrEmpty(strClasses[0]))
{
return;
}
string strDepartmentId = SJTSoft.CMS.Global.Current.UserInfo.DepartmentId;
Department dme = dmeOperate.GetDepartment(Convert.ToInt32(strDepartmentId));
if (!string.IsNullOrEmpty(strDepartmentId))
{
DataTable dt = news.GetReportTotalTable(strDepartmentId, strClasses, txtStartDate.Text, txtEndDate.Text);
if (dt != null)
{
dt.Columns.Add("Colum", typeof(string));
string strchar = "";
string strHeader = "单位 ";
strchar += "";
strchar += " " + dme.DepartmentName + " ";
for (int i = 0; i < strClasses.Length; i++)
{
if (string.IsNullOrEmpty(strClasses[i]))
{
break;
}
string strClassName = news.getClassName(strClasses[i]);
strHeader+=""+ strClassName + "报送" +" ";
strHeader += "" +strClassName + "通过" + " ";
strchar += "" + dt.Rows[0][strClassName + "报送"] + " ";
strchar += "" + dt.Rows[0][strClassName + "通过"] + " ";
}
strchar += "" + dt.Rows[0]["报送总计"] + " ";
strchar += "" + dt.Rows[0]["通过总计"] + " ";
strchar += " ";
strchar += getchildDepartmentList(strDepartmentId, "", strClasses);
strHeader += "报送总计 ";
strHeader += "通过总计 ";
strHeader += "";
dt.Rows[0]["Colum"] = strHeader+strchar;
}
rptReport.DataSource = dt;
rptReport.DataBind();
}
}
///
/// 递归
///
///
///
/// ![](\"../../sysImages/folder/tree_minusmiddle1.gif\")
";
if (dt != null)
{
if (dt.Rows.Count > 0)
{
dt.Columns.Add("Colum", typeof(string));
for (int j = 0; j < dt.Rows.Count; j++)
{
strchar += "";
strchar += "" + sign + dt.Rows[j]["departmentName"] + " ";
string strDepartmentIdTemp = dt.Rows[j]["departmentId"].ToString();
DataTable dtReprot = news.GetReportTotalTable(strDepartmentIdTemp, strClasses, txtStartDate.Text, txtEndDate.Text);
for (int i = 0; i < strClasses.Length; i++)
{
if (string.IsNullOrEmpty(strClasses[i]))
{
break;
}
string strClassName = news.getClassName(strClasses[i]);
strchar += "" + dtReprot.Rows[0][strClassName + "报送"] + " ";
strchar += "" + dtReprot.Rows[0][strClassName + "通过"] + " ";
}
strchar += "" + dtReprot.Rows[0]["报送总计"] + " ";
strchar += "" + dtReprot.Rows[0]["通过总计"] + " ";
strchar += " ";
strchar += getchildDepartmentList(strDepartmentIdTemp, sign, strClasses);
dt.Rows[j]["Colum"] = strchar;
}
dt.Clear();
dt.Dispose();
}
}
return strchar;
#endregion
