Gridview Databound Control

I have a Gridview with databound columns.  When the Gridview is displayed the headers for the databound columns headers appear, along with any data, but the textbox controls do not. The controls seem to be created dynamically when the user selects the edit button.

I am looking for a way to shorten the width of several of these dynamically created textboxes.  

Does anyone have a clue as to how this could be done?

Does the column have an EditItemTemplate defined?

You have to use EditItemTemplate for that.
 <asp:templatefield headertext="Field1">
 
        <itemstyle width=60% wrap=True />
 
        <itemtemplate>
           <asp:label runat="server" 
              id="Field1"
              text='<%# Eval ( "Field1" ) %>' />
        </itemtemplate>
 
        <edititemtemplate>
           <asp:textbox textmode="singleline" runat="server" MaxLength=2
              id="Field1" rows=5 width=40%
              text='<%# Bind ( "Field1" ) %>'  />
        </edititemtemplate>
        
     </asp:templatefield>

Yes, the column does have a EditTemplate Field.

<asp:GridView id="gv_dc" runat="server" OnDataBound="gv_dc_DataBound" DataKeyNames="ClassID,StudentID,ClassMonth,ClassPeriodID" DataSourceID="sql_contactHours" CellPadding="3" BorderWidth="1px" BorderStyle="Dotted" BackColor="White" AllowSorting="True" Width="798px" AllowPaging="True">
<Columns>
    <asp:TemplateField ShowHeader="False">    
<EditItemTemplate>
    <asp:Button id="Button1" runat="server" Text="Update" CommandName="Update" CausesValidation="True"></asp:Button><br />
    <asp:Button id="Button2" runat="server" Text="Cancel" CommandName="Cancel" CausesValidation="False"></asp:Button>
</EditItemTemplate>
<ItemTemplate>
    <asp:Button id="Button1" runat="server" Text="Edit" CommandName="Edit" CausesValidation="False" Width="39px"></asp:Button>
</ItemTemplate>      
    </asp:TemplateField>
</Columns>
<HeaderStyle CssClass="font_tab"></HeaderStyle>
</asp:GridView>

The table does have a primary key field and index, but it also is created dynamically.

Here is code to create the textboxes when the grid loads:

System.Web.UI.WebControls.TextBox tb = new System.Web.UI.WebControls.TextBox();
tb.ID = "day_" + ClassDays[i].ToString();
tb.ControlStyle.Width = 50;
tb.Width = 5;

Neither of the width properties work.  This code is placed within a for loop that runs after the sql statement has been formulated.  It provides the grid with the number of columns, depending on the sql statement.  There are no set number of columns at anytime for the grid, so I don't think I can specify an edittemplate in the way digitalZo is commenting...
