HtmlInputFile value not being passed back RRS feed

  • Question

  • User-2117647399 posted

    I have added an HtmlInputFile HtmlControl to my .aspx page using a "devicespecific" mobile control as follows:

    <mobile:panel id="pnlAttachment" runat="server">
        <mobile:devicespecific id="dspAttachment" runat="server">
                    <input id="fleAttachment" type="file" size="60" runat="server">

    I then try to access the value of the HtmlInputFile control in my C# code as follows:

    System.Web.UI.HtmlControls.HtmlInputFile fleAttachment = (System.Web.UI.HtmlControls.HtmlInputFile) pnlAttachment.Controls[0].FindControl("fleAttachment");
    if (fleAttachment.Value.Trim() != string.Empty)
        //process attachment

    I have used the same technique to obtain the value entered for a multiline TextBox WebControl object, but for some reason the "Value" property of my HtmlInputFile object is always an empty string, even if a value is set on the client by browsing to a file.

    Does anyone have any idea why the value is not being passed back to the server?

    You are right. I just tried this in my VB.NET code and using FindControl, I can not find any HTML controls. FidnControl works fine for other WebControls or Mobile Controls.

    Maybe it got something to do with HTML Controls.

     if you don't mind to see from my idea on Language=VB

    On my WebForm

    <INPUT class="txtname" id="txtFilePriceList" style="WIDTH: 480px; HEIGHT: 17px" type="file" size="60" name="txtFilePriceList" runat="server">

    And when I want to get string from txtFilePriceList, so i get it from
    xxx = txtFilePriceList.PostedFile.FileName

    And when i want to get FileName from it i use
    xFileName = System.IO.Path.GetFileName(txtFilePriceList.PostedFile.FileName)

    i hope it helps!
