HtmlInputFile.Size Property

Gets or sets the width of the text box in which the file path is entered.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

public int Size { get; set; }
/** @property */
public int get_Size ()

/** @property */
public void set_Size (int value)

public function get Size () : int

public function set Size (value : int)

Property Value

The width of the file-path text box. The default value is -1, which indicates that the property has not been set.

Use this property to specify the width of the text box in which to enter the file path.

The following code example demonstrates how to use the Size property to specify the width of the text box in which the user enters the file path. For this example to work properly, you need to create a directory called Temp on your computer's drive C.

<%@ Page Language="C#" AutoEventWireup="True" %>

<script runat="server">
 
  void Button1_Click(object Source, EventArgs e)
  {

    // Make sure a file was submitted.
    if (Text1.Value == "")
    {
      
      Span1.InnerHtml = "Error: You must enter a file name.";
      return;
      
    }

    // Save the file.
    if (File1.PostedFile != null)
    {
      try
      {

        File1.PostedFile.SaveAs("c:\\temp\\" + Text1.Value);
        Span1.InnerHtml = "File uploaded successfully to <b>c:\\temp\\" +
                           Text1.Value + "</b> on the Web server.";
        
      }
      catch (Exception exc)
      {
        
        Span1.InnerHtml = "Error saving file <b>c:\\temp\\" +
                           Text1.Value + "</b><br>" + exc.ToString() + ".";
        
      }
      
    }
    
  }
 
</script>
