GridView列不更改宽度大小

Question

I can't make this GridView column change its width, I have tried this:

<asp:BoundField DataField="ABC" HeaderText="ABC" SortExpression="ABC"  ControlStyle-Width="200%">

Or as pixels:

<asp:BoundField DataField="ABC" HeaderText="ABC" SortExpression="ABC"  ControlStyle-Width="500px">

Or this inside the Boundfield tags:

<ItemStyle HorizontalAlign="Center" Width="500px"/>

Also tried this on code-behind:

Protected Sub GridView3_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView3.RowDataBound
    e.Row.Cells(7).Width = 500
End Sub

How do I get it right?

Answer 1

Here is how it can be done. I am re-sizing the columns who having property : Visible = True

Private Sub GridViewColumnsrResize(ByVal aspectratio As Integer, ByVal gv As DataGridView)
    Try
        Dim col_count As Integer = gv.Columns.Count
        For j As Integer = 0 To col_count - 1
            If gv.Columns(j).Visible = True Then
                gv.Columns(j).Width = gv.Columns(j).Width * aspectratio
            End If
        Next
    Catch ex As Exception
        'output ex
    End Try
End Sub

I just posted this related thread yesterday with a similar issue. Short answer is you can't. There is a workaround as noted in this thread (at the bottom):

How can I print a full gridview area via a custom print window?

Answer 3

Suggestion if you want the value to come in one line , for that you are increasing width then you can try this:
add a cssClass to you Gridview like cssClass=gridContainer ,
add in the .css file:

 .gridContainer
  {
     white-space:nowrap;
  }

for more option, look white-space property

我通过为GridView本身设置固定宽度来解决此问题，它可能不是为特定列设置的，但是它在所有GridView列之间共享其宽度，从而扩展了我想扩展的列。

<asp:GridView ID="GridView3" runat="server" DataSourceID="SqlDataSource4" AutoGenerateColumns="False" CssClass="Gridview" Width="800px">
