I have a GridView with a field that contains long strings of text. I would like to make the grid directly editable, rather than using a details view.
I finally figured out how to make the TextBox in the Edit view bigger, but I cannot find option to to make the text in it wrap or for adding scroll bars.
Is there a way to accomplish what I'm trying to do, either with control properties or through manual coding?
Thanks in advance for your advice.

There is a property for the textbox called "Textmode". change the property to Multiline, it will add a verticle scrollbar and wrap text in the horizontal. It's very unfortunate that nobody has answered you sooner. Aren't these forums monitored by microsoft?

I have same problem. I want to change multiline property of one column in Edit mode. Code is here :

<asp:GridView ID="GridView1" Runat="server" DataSourceID="AccessDataSource1" DataKeyNames="ID" AutoGenerateColumns="False"

AllowSorting="True" AllowPaging="True">

<Columns>

<asp:CommandField ShowEditButton="True" ShowDeleteButton="True" ShowInsertButton="True"></asp:CommandField>

<asp:BoundField ReadOnly="True" HeaderText="ID" InsertVisible="False" DataField="ID"

SortExpression="ID"></asp:BoundField>

<asp:BoundField HeaderText="BaŸlk" DataField="Baslik" SortExpression="Baslik"></asp:BoundField>

<asp:BoundField HeaderText="Metin" DataField="Metin" SortExpression="Metin"></asp:BoundField>

<asp:BoundField HeaderText="BaŸlang&#231; Tarihi" DataField="BaslangicTarihi" SortExpression="BaslangicTarihi"></asp:BoundField>

<asp:BoundField HeaderText="BitiŸ Tarihi" DataField="BitisTarihi" SortExpression="BitisTarihi"></asp:BoundField>

<asp:BoundField HeaderText="Duyuruyu Ekleyen" DataField="Ekleyen" SortExpression="Ekleyen"></asp:BoundField>

<asp:BoundField HeaderText="Aktif" DataField="Aktif" SortExpression="Aktif"></asp:BoundField>

</Columns>

This is not available in a bound field
You will have to set it up as a custom template field with an itemtemplate
and edittemplate that contains a textbox in order to set this up.

<asp:TemplateField HeaderText="Birth Date">
    <ItemTemplate> 
      <asp:Label ID="BirthDateLabel" Runat="Server" 
                 Text='<%# Eval("BirthDate", "{0}") %>' />
    </ItemTemplate>
    <InsertItemTemplate>
      <asp:Calendar ID="InsertBirthDateCalendar" Runat="Server"
                    SelectedDate='<%# Bind("BirthDate") %>' />
    </InsertItemTemplate>
    <EditItemTemplate>
      <asp:Calendar ID="EditBirthDateCalendar" Runat="Server"
                    VisibleDate='<%# Eval("BirthDate") %>'
                    SelectedDate='<%# Bind("BirthDate") %>' />
    </EditItemTemplate>
  </asp:TemplateField>  

If only editing is allowed you do not need the InsertItemTemplate. 
                  

Here is a better example of the code. It is a textbox:

<asp:TemplateField HeaderText="Research/Analysis Issues" HeaderStyle-CssClass=Rtitle >
<ItemTemplate>
<asp:Label ID="Label1" runat="server" CssClass="bodystyle"
Text='<%# Bind("research") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox TextMode=MultiLine Columns=50 Rows=6 ID="EditResearch" runat="server" Wrap="true"
Text='<%# Bind("research") %>'>
</asp:TextBox>
</EditItemTemplate>
<ControlStyle CssClass="bodystyle" />
<HeaderStyle Wrap="false" />
</asp:TemplateField>

Experiment with the column and row number that is best for your data.

I struggled with trying to prevent text from wrapping in my GridView and have come to the conclusion that NONE of the property controls seem to be able to provide "Wrap=False".

I solved the presentation issue by setting the column to a template field and the replacing the Label control in the Item Template with a TextBox control. The text box has a Wrap property which obeys "False". I then set the text box background to transparent and its borders to 0px. It sits very happily in my GridView and truncates the text, as desired.

or you can just use CSS
