将数据从Excel导入GridView [英] Import Data from Excel to GridView
问题描述
亲爱的，
以下是我的代码，我已成功将数据从Excel导入GridView。
问题是我有两个Column Hour&描述。当我导入到GridView时某些描述数据没有完全导入到GridView中，一些文本丢失了。意味着
在Excel中
小时说明
1 abcdefghijklmnopqrstuuudddd
在GridView
小时说明
1 abcdefghijklmno
文本大约64字左右，其中包括所有字符，如2 7/8
这里VB.Net代码
进口System.Data
进口System.Data.OleDb
进口System.IO
部分类WebForm1
继承System.Web.UI.Page
受保护的子Page_Load（ByVal sender As Object，ByVal e As EventArgs）
End Sub
受保护的子btnImport_Click（ByVal发送者为对象，ByVal e As EventArgs）
Dim connString As String =
Dim strFileType As String =。xls
Dim path__1 As String =c：\ccc.xls
'到Excel W的连接字符串orkbook
如果strFileType.Trim（）=。xls那么
connString =Provider = Microsoft.Jet.OLEDB.4.0; Data Source =& path__1& ;扩展属性=Excel 8.0; HDR =是; IMEX = 2
ElseIf strFileType.Trim（）=。xlsx然后
connString = Provider = Microsoft.ACE.OLEDB.12.0; Data Source =& path__1& ;扩展属性=Excel 12.0; HDR =是; IMEX = 2
结束如果
Dim query As String =SELECT [Hours（hr） ]，[描述] FROM [sheet1 $]
Dim conn As New OleDbConnection（connString）
如果conn.State = ConnectionState.Closed那么
conn.Open（）
结束如果
Dim cmd As New OleDbCommand（query，conn）
Dim da As New OleDbDataAdapter（cmd ）
Dim ds作为新数据集（）
da.Fill（ds）
grvExcelData.DataSource = ds.Tables（0）
grvExcelData.DataBind（）
da.Dispose（）
conn.Close（）
conn.Dispose（）

Dear,
Below is my code where i'm successfully import data from Excel to GridView.
The Problem is I have two Column Hour & Description. When i import to an GridView Some of the Description data is not fully imported to an GridView some of the Text is missing. Means

Hour Description
1 abcdefghijklmnopqrstuuudddd
In GridView
Hour Description
1 abcdefghijklmno
The Text is quit big around 64 words which inludes all characters also like 2 7/8"

Dim connString As String = ""
Dim strFileType As String = ".xls"
Dim path__1 As String = "c:\ccc.xls"
'Connection String to Excel Workbook
If strFileType.Trim() = ".xls" Then
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & path__1 & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=2"""
ElseIf strFileType.Trim() = ".xlsx" Then

Dim query As String = "SELECT [Hours (hr)],[Description] FROM [sheet1$]"
Dim conn As New OleDbConnection(connString)
If conn.State = ConnectionState.Closed Then
conn.Open()
End If
Dim cmd As New OleDbCommand(query, conn)
Dim da As New OleDbDataAdapter(cmd)
Dim ds As New DataSet()
da.Fill(ds)
grvExcelData.DataSource = ds.Tables(0)
