web下vs2008+crystal report 不预览直接打印
下载了一个PrintControl.cab(vs2008用的)
然后在webconfig中设置:
代码
1 <configSections>
2 <sectionGroup name="businessObjects">
3 <sectionGroup name="crystalReports">
4 <section name="printControl" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null" /> </sectionGroup>
5 </sectionGroup>
6 </configSections>
7 <businessObjects>
8 <crystalReports>
9 <printControl>
10 <add key="url" value="WebProducer/PrintControl.cab" />
11 </printControl>
12 </crystalReports>
13 </businessObjects>
2 <sectionGroup name="businessObjects">
3 <sectionGroup name="crystalReports">
4 <section name="printControl" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null" /> </sectionGroup>
5 </sectionGroup>
6 </configSections>
7 <businessObjects>
8 <crystalReports>
9 <printControl>
10 <add key="url" value="WebProducer/PrintControl.cab" />
11 </printControl>
12 </crystalReports>
13 </businessObjects>
在需要打印的页面上添加以下代码:
1 <object id="CrystalPrintControl" classid="CLSID:83A3D1E4-ADC6-434D-9B61-B8CBA6183441"
2 codebase="PrintControl.cab" version="10,5,1,2285" height="0px"
3 viewastext>
4 </object>
2 codebase="PrintControl.cab" version="10,5,1,2285" height="0px"
3 viewastext>
4 </object>
设置height="0px"主要是让 object不显示在页面上;
添加水晶报表crystalReportViewr
代码
1 <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true"
2 EnableDrillDown="false" DisplayGroupTree="false" style="font-size: 11px"
3 HasCrystalLogo="False" BestFitPage="False" HasExportButton="False"
4 PrintMode="ActiveX" Height="40px" Width="0px" />
2 EnableDrillDown="false" DisplayGroupTree="false" style="font-size: 11px"
3 HasCrystalLogo="False" BestFitPage="False" HasExportButton="False"
4 PrintMode="ActiveX" Height="40px" Width="0px" />
将width设置为“0”让客户无法看见crystalReportViewr,但实际上crystalReportViewr还是存在于页面上的。本来想把height设置为“0px”但总提示出错,结果设置为这个数运行后同样看不到crystalReportViewr.就不理它了。
在前台页面上加上脚本调用水晶报表自带的打印按钮
1
2 <script type="text/javascript">
3 function printIt() {
4 document.getElementsByName("CrystalReportViewer1$ctl02$ctl01").item(0).click();
5 return false;
6 }
7 </script>
2 <script type="text/javascript">
3 function printIt() {
4 document.getElementsByName("CrystalReportViewer1$ctl02$ctl01").item(0).click();
5 return false;
6 }
7 </script>
然后添加自定义打印按钮:
<input id="bt1" type="button" onclick="printIt();"/>
后台方面绑定水晶报表:
代码
protected void Page_Load(object sender, EventArgs e)
{
//if (!IsPostBack)
//{
//}
//本来是想写在IsPostBack里面的,但这样写就提示您请求的报表需要更多信息... 所以只好写在外面 ,原因是打印的时候还要重新绑定水晶报表。
BindCRV();
}
void BindCRV
{
CrystalDecisions.Web.CrystalReportSource crs = new CrystalDecisions.Web.CrystalReportSource();
PrintDocument prtdoc = new PrintDocument();
string strDefaultPrinter = prtdoc.PrinterSettings.PrinterName;
try
{
crs.ReportDocument.Load(reportpath);
crs.ReportDocument.SetDataSource(ds.Tables[0]);
crs.DataBind();
CrystalReportViewer1.ReportSource = crs;
CrystalReportViewer1.DataBind();
}
catch (Exception ex)
{
//UnCommon.ShoMessage(ex.Message, false, this);
// WSBG.UnCommon.ExecuteScript("alert('" + ex.Message + "')", this);
}
finally
{
crs.Dispose();
GC.Collect();
}
}
{
//if (!IsPostBack)
//{
//}
//本来是想写在IsPostBack里面的,但这样写就提示您请求的报表需要更多信息... 所以只好写在外面 ,原因是打印的时候还要重新绑定水晶报表。
BindCRV();
}
void BindCRV
{
CrystalDecisions.Web.CrystalReportSource crs = new CrystalDecisions.Web.CrystalReportSource();
PrintDocument prtdoc = new PrintDocument();
string strDefaultPrinter = prtdoc.PrinterSettings.PrinterName;
try
{
crs.ReportDocument.Load(reportpath);
crs.ReportDocument.SetDataSource(ds.Tables[0]);
crs.DataBind();
CrystalReportViewer1.ReportSource = crs;
CrystalReportViewer1.DataBind();
}
catch (Exception ex)
{
//UnCommon.ShoMessage(ex.Message, false, this);
// WSBG.UnCommon.ExecuteScript("alert('" + ex.Message + "')", this);
}
finally
{
crs.Dispose();
GC.Collect();
}
}
终于大功公成,不预览直接打印
