    Any ideas on this one?

    The base class includes the field 'txtVenID', but its type (System.Web.UI.WebControls.TextBox) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlInputText).

    Source Error:


    Line 23:     <td style="WIDTH: 205px"><FONT size="2"
    Line 24:       >Vender ID:</FONT></td>
        Line 25:     <td><input id="txtVenID" style="WIDTH: 220px" type="text"
    Line 26:       size="20" name="txtVenID" runat="server"></td>
    Line 27:     <td><FONT size=2>Vendor

    If you want an Html text field control:
    <td>
       <INPUT id="txtVenID" style="WIDTH: 220px" type="text" size="20" name="txtVenID" runat="server">
    </td>

    Else if you want to use a TextBox web control:
    <td>
       <asp:TextBox id="txtVenID" style="WIDTH: 220px" runat="server" MaxLength="20">
       </asp:TextBox>
    </td>

    when I use an Html text field I get get the above error.

    When I use and TextBox web control, the attributes name, type and size are underlined with  statements such as "could not find any attribute 'name' of element 'TextBox'.

    I heard that Visual Studio messes around with your html code?????

    Actually there are no "name" / "type" / "size" properties for TextBox web server control.. so the error you have received is genuine... no messing around :))

    You need to write it like this...
    <asp:TextBox id="txtVenID" style="WIDTH: 220px" runat="server" MaxLength="20">

    Is there another control with the same id "txtVenID".. The error message seems to say so..

    The base class includes the field 'txtVenID', but its type (System.Web.UI.WebControls.TextBox) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlInputText).

    Does this give an error message too??
    <td>
       <INPUT id="txtVenID" style="WIDTH: 220px" type="text" size="20" name="txtVenID" runat="server">
    </td>

    No other control named txtVenID. This page does consist of 30+ controls.

    Yes, it gets the same error.

    This page was built originally with web controls on gridflow. I was having trouble with some controls roaming so I which to flowgrid and built Html controls. I never could get it to preview so I copied the Html into a clean project and it works with no problems. Maybe the problem is deeper than the Html code.

    Okay..
    I think your HTML is okay.. there is probably a TextBox declared with the same id in the code-behind file. Look for something like this in the code-behind file (.aspx.cs)..

    protected System.Web.UI.WebControls.TextBox txtVenID;

    And remove that declaration, it would be a remnant of the old web controls page.

    I commented out all the Protected WithEvents and got the same error for txtVenID. I might have to redo the code-behide page also then add that new page to the project.

    ohh.. much as I hate to say it.. I think that might take the error out.. it is obvious that some part of 'old code' still thinks that  'txtVenID' is a TextBox and not a Html Control.

    On the other hand, why don't you keep it as a TextBox.. web server controls are far better than Html controls.

    In ASP.NET, we use Html controls only when a suitable web server control isn't available or when we just need plain HTML stuff.. no server manipulations.. or for a specific requirement.

    It might be a better idea to stick with web server control.. to the extent of the availability of server-side handling in code etc.

    Use an Html table to position controls.. no reason to use Html controls in ASP.NET, when you have far more advanced set of Web server controls!!!
