GridView的列的数据分行显示

今天，在将数据绑定到GridView时，发现其中一个列的数据特别的长，占去了页面大部分的宽度，如下图，

怎样使这列的数据像旁边的两列一样显示呢？

首先，设置当前列的Item_style中的Wrap 属性为True。一般，这样就可以了。如果数据格式是像上图显示的一样，那就麻烦了。 因为，AutoWrap 只会在遇到空格才会换行。

在我的项目中，因为这行数据是在绑定后插入的，所以解决起来比较容易。

Protected Sub FillTest()
Dim cs As String = ConfigurationManager.ConnectionStrings( " TestConnectionString " ).ConnectionString.ToString
Dim cn As New SqlClient.SqlConnection(cs)
Dim cmdText As String = " SELECT qr.character1,qr.character2 FROM table1 qr, table2 qp Where qr.plan_id = qp.plan_id "
Dim cmd As New SqlClient.SqlCommand(cmdText, cn)
Dim charSeparators() As Char = { " ; " c}
Dim da As New SqlClient.SqlDataAdapter(cmd)
cmd.CommandTimeout = 600
Dim hstblSalesOffice As New Hashtable

Dim salesOffices, hshKey, hshValue, LBPPersonName As String
Dim ds As New Data.DataSet
Dim drChar As DataRow
da.Fill(ds)
For Each drChar In ds.Tables( 0 ).Rows
LBPPersonName = drChar( " character1 " )
salesOffices = drChar( " character2 " )
For Each hshKey In salesOffices.Split(charSeparators, StringSplitOptions.None)
If hstblSalesOffice.ContainsKey(hshKey) Then
If (txtCSPerson.Text.Trim() = String .Empty) Then
hshValue = hstblSalesOffice.Item(hshKey)
' Column wrap will work only when there are some spaces between strings
hshValue = hshValue & " / " & LBPPersonName
hstblSalesOffice.Item(hshKey) = hshValue
Else
hshValue = txtCSPerson.Text.ToString
hstblSalesOffice.Item(hshKey) = hshValue
End If
Else
hstblSalesOffice.Add(hshKey, LBPPersonName)
End If
Next
Next
Session( " CSPerson " ) = hstblSalesOffice
ds.Dispose() : da.Dispose() : cmd.Dispose() : cn.Dispose()
End Sub
