在Datagridview中打印彩色的行 [英] Print Colored Rows In A Datagridview

问题描述

大家好

所以我有2个datagridviews比较它们之间的信息，如果匹配，它将绿色的行涂成绿色，完成所有空白后将红色的行涂成颜色，所以主要的事情是我不知道如何只打印红色行.

这是我正常打印的方法

Hello Everyone

So I have 2 datagridviews that compare information between them and if it does match it colors the rows in green and after its done all the white spaces colors the rows in RED, so the main thing is that i dont know how to print only the RED rows.

This is the method that i use to print normally

PRINT BUTTON

Dim dlg As New PrintPreviewDialog()
    
            dlg.Document = PrintDocument2
    
            dlg.ShowDialog()
    
            Dim psDlg As New PageSetupDialog

            ' Right Align - User Name
            e.Graphics.DrawString(sUserName, Emp_attDataGridView.Font, Brushes.Black, e.MarginBounds.Left + (e.MarginBounds.Width - e.Graphics.MeasureString(sPageNo, Emp_attDataGridView.Font, e.MarginBounds.Width).Width), e.MarginBounds.Top + e.MarginBounds.Height + 7)

推荐答案

您发布了很多代码，但其中很多确实不相关.下次您发布问题时，请将其缩小到您遇到的问题.

在该代码块中的某个位置，您正在循环遍历数据网格中的每一行...就在此位附近:

You posted a lot of code and a lot of it really wasn''t relevant. Next time you post a question, please narrow it down to just what you are having trouble with.

Somewhere in that code block you are looping through each row in the data grid...Right around this bit:

'...
Do While nRowPos < Emp_attDataGridView.Rows.Count

               Dim oRow As DataGridViewRow = Emp_attDataGridView.Rows
(nRowPos)
'...

(我个人将使用For Each块而不是Do While，但每个人自己使用)

此时，您正在抓取一行，稍后再逐个单元地进行打印.因此....如果该行的背景颜色为红色，请跳过打印该行的代码.我认为它看起来像这样:

(Personally I''d use a For Each block instead of a Do While, but to each his own)

At this point, you are grabbing a row which later on you are printing cell by cell. So....if the row has a red background color, skip the code that prints it. I think it would look something like this:

If oRow.Cells(0).Style.BackColor = Color.Red Then
                Continue Do 
'Continue Do transfers execution immediately to the next iteration of the Do Loop
            End If
