何绘制AjaxControlToolkit的TabPanel为位

本文介绍了如何绘制AjaxControlToolkit的TabPanel为位图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个包含许多标签阿贾克斯标签的容器。我想通过每个选项卡循环并绘制标签面板内容的位图。

这是我目前的codeS:

 的foreach(在container.Controls obj对象)
            {
                如果(obj是AjaxControlToolkit.TabPanel)
                {
                    AjaxControlToolkit.TabPanel一个tabpanel =(AjaxControlToolkit.TabPanel)目标文件;                    位图m_Bitmap =新位图(Screen.PrimaryScreen.Bounds.Width,Screen.PrimaryScreen.Bounds.Height);                    显卡显卡= Graphics.FromImage(m_Bitmap为System.Drawing.Image对象);
                    graphics.CopyFromScreen(25,25,25,25,m_Bitmap.Size);                    m_Bitmap.Save(@C:\\用户\\用户\\桌面\\项目\\ PROJECT1 \\来源$ C ​​$ C \\ PROJECT1 \\图片\\+ tabPanel.HeaderText +.JPG,System.Drawing.Imaging.ImageFormat.Jpeg) ;
                }
            }

现在我能循环thorugh在该选项卡容器中的每个选项卡面板和屏幕截图整个网页,然后保存图像文件夹的位图图像。但我想截图/位图只是标签面板的内容。

问:如何绘制AjaxControlToolkit的TabPanel我目前的codeS为位图

请指引我在这,谢谢。


解决方案

  1. 从客户端code获取的TabPanel。这是样品code:

VAR TabContainer的= $找到(Content_DemoContent_Tabs);
对于(VAR I = 0; I< tabContainer.get_tabs()长;我++)
{
    tabContainer.set_activeTabIndex(ⅰ);
    VAR元= tabContainer.get_tabs()[我] ._元;
}


  • 计算在屏幕坐标中的每个元素的位置。这是相当复杂和不可靠的任务,但你可以看到如何在这里做到这一点:http://stackoverflow.com/a/21274679/644496

  • 发送数据到服务器进行屏幕截图。这是广泛的,但众所周知的任务,所以您可以选择这样做的任何方式。

  • I have ajax tab container that contains many tabs. I want to loop through each tab and draw the tab panel content to bitmap.

    This is my current codes:

    foreach (object obj in container.Controls)
                {
                    if (obj is AjaxControlToolkit.TabPanel)
                    {
                        AjaxControlToolkit.TabPanel tabPanel = (AjaxControlToolkit.TabPanel)obj;
    
                        Bitmap m_Bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
    
                        Graphics graphics = Graphics.FromImage(m_Bitmap as System.Drawing.Image);
                        graphics.CopyFromScreen(25, 25, 25, 25, m_Bitmap.Size);
    
                        m_Bitmap.Save(@"C:\Users\user\Desktop\Project\Project1\Source Code\Project1\Image\" + tabPanel.HeaderText + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
                    }
                }
    

    Now I am able to loop thorugh each tab panel in the tab container and screenshot the whole webpage, then save the bitmap image in Image folder. But I want to screenshot/bitmap just the tab panel content.

    Question: How to Draw AjaxControlToolkit TabPanel to Bitmap with my current codes?

    Please guide me on this, thanks.

    解决方案
    1. Get TabPanel from client code. This is sample code:
    var tabContainer = $find("Content_DemoContent_Tabs");
    for(var i = 0; i < tabContainer.get_tabs().length; i++)
    {
        tabContainer.set_activeTabIndex(i);
        var element = tabContainer.get_tabs()[i]._element;
    }
    
    1. Calculate position of each element in screen coordinates. This is quite complex and not reliable task, but you can see how to do it here: http://stackoverflow.com/a/21274679/644496
    2. Send this data to server to make a screenshot. This is broad, though well-know task, so you can choose any way of doing it.
