ActiveReport中如何动态地添加控件?

Question

要求由客户动态的调整需要打印的数据列.这就要求activereport的控件最好能够动态的增减.谁有这方面的经验?

Answer 1

我只有动态增加label的，
for (int i = 0;i < nTotals;i++)
{//Get the Panel Size
int width = pictureBox1.Size.Width;
int height = pictureBox1.Size.Height;Label lb=new Label();
lb.Location=new Point(i*20,i*30);
lb.Size= new Size(158,30);
lb.BorderStyle = BorderStyle.FixedSingle;
//lb.AutoSize = true;
lb.Name = "lbName"+i;
lb.Text = ChannelName;
this.panel1.Controls.Add(lb);
lb.BackColor = System.Drawing.Color.Transparent;
lb.DoubleClick += new System.EventHandler(this.label_DoubleClick);
lb.MouseHover += new System.EventHandler(this.label_MouseHover);
lb.MouseLeave += new System.EventHandler(this.label_MouseLeave);
lb.MouseDown +=new MouseEventHandler(this.label_MouseDown);
lb.Tag = ***;
lb.BringToFront();
lb.BackColor = System.Drawing.Color.LemonChiffon;this.panel1.Invalidate();
}

楼上的楼上能在Winform里用,在Ar里用还是不行
动态创建控件很麻烦,主要是排版的问题,这是我以前写的打印工资条的代码,工资项目是不固定的,故我只能用动态的加列,
private void constructReport()
{
this.Detail.CanGrow=true;
this.Detail.CanShrink=true;
this.Detail.KeepTogether=true;
for(int i=0;i<dt.Columns.Count;i++)
{
if(i>8 && i%9==0)
{
this.m_currentY=this.m_currentY+this.m_defaultHeight*2;
this.m_currentX=0;
count++;
} TextBox txt=new TextBox();
txt.Location=new PointF(this.m_currentX,this.m_currentY);
this.m_currentX=this.m_currentX+this.m_defaultWidth;
txt.Width=this.m_defaultWidth;
txt.Height=this.m_defaultHeight;
txt.Border.BottomStyle=BorderLineStyle.Solid;
txt.Border.TopStyle=BorderLineStyle.Solid;
txt.Border.LeftStyle=BorderLineStyle.Solid;
txt.Border.RightStyle=BorderLineStyle.Solid;
txt.Text=dt.Columns[i].ColumnName.Trim();
txt.Alignment=TextAlignment.Center;
txt.VerticalAlignment=VerticalTextAlignment.Middle;
this.Detail.Controls.Add(txt);      }
this.m_currentX=0f;
this.m_currentY=0.2f;
for(int i=0;i<dt.Columns.Count;i++)
{
if(i>8 && i%9==0)
{
this.m_currentY=this.m_currentY+this.m_defaultHeight*2;
this.m_currentX=0;
count++;
}
TextBox txt=new TextBox();
txt.Location=new PointF(this.m_currentX,this.m_currentY);
this.m_currentX=this.m_currentX+this.m_defaultWidth;
txt.Width=this.m_defaultWidth;
txt.Height=this.m_defaultHeight;
txt.Border.BottomStyle=BorderLineStyle.Solid;
txt.Border.TopStyle=BorderLineStyle.Solid;
txt.Border.LeftStyle=BorderLineStyle.Solid;
txt.Border.RightStyle=BorderLineStyle.Solid;
txt.Alignment=TextAlignment.Center;
txt.VerticalAlignment=VerticalTextAlignment.Middle;
txt.DataField=dt.Columns[i].ColumnName;
if(dt.Columns[i].DataType.ToString()=="System.Decimal")
txt.OutputFormat="#,##0.00";
this.Detail.Controls.Add(txt);
     }
TextBox txt1=new TextBox();
txt1.Location=new PointF(0f,this.m_currentY+0.2f);
this.m_currentX=this.m_currentX+this.m_defaultWidth;
txt1.Width=this.m_defaultWidth;
txt1.Height=this.m_defaultHeight;
this.Detail.Controls.Add(txt1);
this.Detail.Height=this.m_defaultHeight*count+1f;

}
