CrystalReportViewer print

Question

我想在ASP.NET C＃中訪問CrystalReportViewer的Print事件（當我單擊CrystalReportViewer的Print按鈕時），怎麼樣？

Answer 1

像下面的東西應該工作。希望能幫助到你。

public Form1() 
    { 
     InitializeComponent(); 
     foreach (ToolStrip ts in crystalReportViewer1.Controls.OfType<ToolStrip>()) 
     { 
      foreach (ToolStripButton tsb in ts.Items.OfType<ToolStripButton>()) 
      { 
       //hacky but should work. you can probably figure out a better method 
       if (tsb.ToolTipText.ToLower().Contains("print")) 
       { 
        //Adding a handler for our propose 
        tsb.Click += new EventHandler(printButton_Click); 
       } 
      } 
     } 
    } 

    private void printButton_Click(object sender, EventArgs e) 
    { 
     MessageBox.Show("Printed"); 
    }

不是一個真正的新的答案，但這裏是在C++上面使用.NET Framework對象等：

CRXViewerNetControl(void) 
    { 
     InitializeComponent(); 

     // OK, go though the CRViewer and find the Print Button in the toolbar. When we find it, 
     // attach a "Click" event handler so that we can detect the operator clicking the button to 
     // print the report. 
     for (Int32 i = 0; i < CRXViewer->Controls->Count; i++) 
     { 
      if (dynamic_cast<System::Windows::Forms::ToolStrip^>(CRXViewer->Controls[i])) 
      { 
       System::Windows::Forms::ToolStrip^ ctlToolStrip = dynamic_cast<System::Windows::Forms::ToolStrip^>(CRXViewer->Controls[i]); 
       for (int j = 0; j < ctlToolStrip->Items->Count; j++) 
       { 
        if (dynamic_cast<System::Windows::Forms::ToolStripButton^>(ctlToolStrip->Items[j])) 
        { 
         System::Windows::Forms::ToolStripButton^ ctlToolStripButton = dynamic_cast<System::Windows::Forms::ToolStripButton^>(ctlToolStrip->Items[j]); 
         if (ctlToolStripButton->ToolTipText->ToLower()->Contains("print")) 
         { 
          //Adding a handler for our propose 
          ctlToolStripButton->Click += gcnew System::EventHandler(this, &CRXViewerNetControl::printButton_Click); 
         } 
        } 
       } 
      } 
     } 

    } 

private: System::Void printButton_Click(System::Object^ sender, System::EventArgs^ e) 
    { 
     MessageBox::Show("Printed"); 
    }
