Uploading files whose size> 1MB and save to a folder

I am trying to upload files to a folder on my harddisk whose size is greater than 500kb but i always get the message Http Error 400 BAD REQUEST . IIS is not installed on my profile so i didnt add <system.webserver> settings to the web.config file ('m using ASP.Net Development server i.e inbuilt)
As per my knowledge i had made changes to the web.config file as below

<add name="connection" connectionString="server=PRATHAPG\SQLEXPRESS;database=Prathap;trusted_connection=true"/>

<compilation debug="true" targetFramework="4.0"/>
<httpRuntime maxRequestLength="204800" executionTimeout="3600" maxQueryStringLength="1024000"/>


The code for uploading the files

SqlConnection Cn;
SqlCommand Cmd;
SqlDataAdapter Da;
DataSet Ds;

protected void Page_Load(object sender, EventArgs e)
string conn = ConfigurationManager.ConnectionStrings["connection"].ConnectionString;
Cn = new SqlConnection(conn);
Ds = new DataSet();
Cmd = new SqlCommand();
Cmd.Connection = Cn;

protected void btnupload_Click(object sender, EventArgs e)
if (ful.HasFile)
string path = "~/Docs/" + ful.FileName;
string filename = Path.GetFileName(ful.PostedFile.FileName);
string fileExtension = Path.GetExtension(ful.PostedFile.FileName.ToLower());
if (fileExtension == ".pdf" || fileExtension == ".txt" || fileExtension == ".docx" || fileExtension == ".doc" || fileExtension == ".xls" || fileExtension == ".xlsx" || fileExtension == ".ppt" || fileExtension == ".pptx")
string documentType = string.Empty;
switch (fileExtension)
case ".pdf":
documentType = "application/pdf";

Cmd.CommandText = "Files_Insert";
Cmd.CommandType = CommandType.StoredProcedure;
Cmd.Parameters.AddWithValue("@Filename", filename);
Cmd.Parameters.AddWithValue("@Contenttype", documentType);
Cmd.Parameters.AddWithValue("@Fileurl", path);
lblmsg.Text = "Uploaded Successfully";
lblmsg.Text = "Only Pdf,Word,Excel,Text files can be Uploaded";

Can you please suggest any other alternative and let me know the reason y i am not able to upload files whose size > 500KB even when i added necessary settings in web.config file.
