Hello.
I have a gridView with Edit button. My columns are template columns such as:

<asp:TemplateField HeaderText="Start Date">
                    <ItemTemplate>
                        <asp:Label ID="lblStartDate1" runat="server" Text='<%# Eval("StartDate")>'></asp:Label>                        
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox ID="txtStartDate1" Text='<%# Eval("StartDate")%>' runat="server"></asp:TextBox>                        
                    </EditItemTemplate>                    
                </asp:TemplateField>

My gridView is nested. So whenever a row doesn't have children, all columns should be editable, and when a row has children, some columns become summary columns, and should not be editable.
How would I achive this with templateFields? I just want to show a label like it is, not convert it into a textbox.

Also consider moving both controls into the ItemTemplate. Then show/hide the label/textbox based on you condition for showing the field.

in ASPX:

<asp:TemplateField HeaderText="Start Date">
       <ItemTemplate>
              <asp:Label ID="lblStartDate1" runat="server" Text='<%# Eval("StartDate")>'></asp:Label>                        
              <asp:TextBox ID="txtStartDate1" Text='<%# Eval("StartDate")%>' runat="server"></asp:TextBox>
       </ItemTemplate>                
</asp:TemplateField>

in ASPX.VB.. DataBound event of gridView:

If e.Row.RowType = DataControlRowType.DataRow Then

     Dim myTextBox = CType(e.Item.Cells(index).Controls(1), TextBox)
     Dim myLabel = CType(e.Item.Cells(index).Controls(0), Label)
     
     myTextBox.Visible =Not FIELD_SHOULD_BE_READONLY_CONDITION
     myLabel.Visible = FIELD_SHOULD_BE_READONLY_CONDITION

End If
