从vb.net datagridview生成html表格 [英] Generating html table from vb.net datagridview
问题描述
我需要根据datagridview中的数据生成HTML表格。 （如果有人想知道，我使用vb.net）
datagridview由5列组成，而行的数量可以根据
我试图在下面生成的表代码的结构如下：
< tr>
< td> column 1 row1< / td>
< td>栏2 row1< / td>
< td>栏3 row1< / td>
< td>栏4 row1< / td>
< td>列5 row1< / td>
< / tr>
< tr>
< td>第1列第2行< / td>
< td>第2列第2行< / td>
< td>栏3 row2< / td>
< td>列4 row2< / td>
< td>列5 row2< / td>
< / tr>
< tr>
< td>第1列第3行< / td>
< td>第2栏第3行< / td>
< td>栏3 row3< / td>
< td>栏4 row3< / td>
< td>列5 row3< / td>
< / tr>
ect ....
并且在完整的行被保存之前和之后的标签。下面的代码显示了我试图解决这个问题的尝试，但是我迷失了方向，然后发现它很高兴在论坛上寻求帮助。
注意:(请原谅在代码中出现的错误，这些错误是在调整后才开始工作的）。
Private Sub Button1_Click（sender As Object，e As EventArgs）Handles Button1.Click
Dim col1 As String
Dim col2 As String
Dim Count As Integer = 1
For i As Integer = 0到DataGridView1.Rows.Count - 1
如果Count = 5那么
对于每行DataGridViewRow在DataGridView1.Rows中
如果不是row.IsNewRow然后
col1 = row.Cells（0）.Value.ToString
col2 = row.Cells（1）.Value.ToString
MsgBox（< tr>< td>& col1&& col2&< / td>< / tr>）
Count = 0
End If
Next
ElseIf Not Count = 5 Then
For j As Integer = 0 To DataGridView1.Rows.Count - 1
对于每行2作为DataGridViewRow在DataGridView1.Rows
如果不是row2.IsNewRow然后
col1 = row2.Cells（0）.Value.ToString
col2 = row2.Cells（1）.Value.ToString
MsgBox（< td>& col1& & col2& amp; < / td>）
结束If
Next
Count = +1
Next
End If
Next
结束
我最近使用的代码将DataGridView呈现到HTML表格中用于发送电子邮件。它使用C＃，但翻译起来应该不会太困难。它应该是非常简单的，你添加HTML元素，自动将HTML应用到数据。 $ b
使用System.Web.UI;
使用Web = System.Web.UI.WebControls;
...
私有字符串DataGridViewToHTML（）
{
StringWriter sw = new StringWriter（）;
HtmlTextWriter hw = new HtmlTextWriter（sw）;
Web.Label introBody = new Web.Label（）;
introBody.Text =;
introBody.ID =bodyText;
introBody.RenderControl（hw）;
hw.WriteBreak（）;
hw.WriteBreak（）;
//数据表。
Web.Table tbl = new Web.Table（）;
tbl.GridLines = Web.GridLines.Both;
Web.TableHeaderRow thr = new Web.TableHeaderRow（）;
//添加列标题
foreach（DataGridViewColumn col in dgvRcds.Columns）
{
Web.TableHeaderCell thc = new Web.TableHeaderCell（）;
thc.Text = col.HeaderText;
thr.Controls.Add（thc）;
}
tbl.Controls.Add（thr）;
//添加每行
foreach（DataGridViewRow在dgvRcds.Rows中的行）
{
Web.TableRow tr = new Web.TableRow（）;
foreach（DataGridViewCell val in row.Cells）
{
Web.TableCell tc = new Web.TableCell（）;
tc.Text = val.EditedFormattedValue.ToString（）;
tr.Controls.Add（tc）;
}
tbl.Controls.Add（tr）;
}
//在html
中渲染表tbl.RenderControl（hw）;
//返回原始html字符串。
return sw.ToString（）;
}
I need to generate a HTML table based upon data found in my datagridview. (I use vb.net if anyone wants to know)
The datagridview consists out of 5 columns whilst the amount of rows are pendable on how many actions have been recorded by the end user.
The structure of the table code I am trying to generate in as follows:
<tr>
<td>column 1 row1</td>
<td>column 2 row1</td>
<td>column 3 row1</td>
<td>column 4 row1</td>
<td>column 5 row1</td>
</tr>
<tr>
<td>column 1 row2</td>
<td>column 2 row2</td>
<td>column 3 row2</td>
<td>column 4 row2</td>
<td>column 5 row2</td>
</tr>
<tr>
<td>column 1 row3</td>
<td>column 2 row3</td>
<td>column 3 row3</td>
<td>column 4 row3</td>
<td>column 5 row3</td>
</tr>
ect....
The trouble Im having though is placing the and tags after and before a complete row has been saved. the following code shows my attempt at trying to resolve this problem but i have lost my way and then found it high time to ask around on the forum for help
NOTE:(please excuse the errors in the code which came about after tweaking around trying to get things to work).
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim col1 As String
Dim col2 As String
Dim Count As Integer = 1
For i As Integer = 0 To DataGridView1.Rows.Count - 1
If Count = 5 Then
For Each row As DataGridViewRow In DataGridView1.Rows
If Not row.IsNewRow Then
col1 = row.Cells(0).Value.ToString
col2 = row.Cells(1).Value.ToString
MsgBox("<tr><td>" & col1 & " " & col2 &"</td></tr>")
Count = 0
End If
Next
ElseIf Not Count = 5 Then
For j As Integer = 0 To DataGridView1.Rows.Count - 1
For Each row2 As DataGridViewRow In DataGridView1.Rows
If Not row2.IsNewRow Then
col1 = row2.Cells(0).Value.ToString
col2 = row2.Cells(1).Value.ToString
MsgBox("<td>" & col1 & " " & col2 & "</td>")
End If
Next
Count = +1
Next
End If
Next
End
Here's an example of some code I used recently that renders a DataGridView into an HTML table for emailing. It is in C#, but it shouldn't be too difficult for you to translate. It should be pretty straightforward, you're adding HTML elements that apply HTML to the data automatically.
using System.Web.UI;
using Web = System.Web.UI.WebControls;
// ...
private string DataGridViewToHTML()
{
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Web.Label introBody = new Web.Label();
introBody.Text = "";
introBody.ID = "bodyText";
introBody.RenderControl(hw);
hw.WriteBreak();
hw.WriteBreak();
//Table for data.
Web.Table tbl = new Web.Table();
tbl.GridLines = Web.GridLines.Both;
Web.TableHeaderRow thr = new Web.TableHeaderRow();
// add column headers
foreach(DataGridViewColumn col in dgvRcds.Columns)
{
Web.TableHeaderCell thc = new Web.TableHeaderCell();
thc.Text = col.HeaderText;
thr.Controls.Add(thc);
}
tbl.Controls.Add(thr);
//add each row
foreach(DataGridViewRow row in dgvRcds.Rows)
{
Web.TableRow tr = new Web.TableRow();
foreach(DataGridViewCell val in row.Cells)
{
Web.TableCell tc = new Web.TableCell();
tc.Text = val.EditedFormattedValue.ToString();
tr.Controls.Add(tc);
}
tbl.Controls.Add(tr);
}
//render table in html
tbl.RenderControl(hw);
//return raw html string.
return sw.ToString();
}
