Hi Frends I am using the ASP.Net FileUpload control to upload the file and using AjaxMethod to save the file on Server but I am getting the FileUpload as null...... anybody pls help....

[Ajax.AjaxMethod()]
public bool VerifyUploadedData()
{

    try
    {
        if (FileUpload1.HasFile)
        {
            sFileType = System.IO.Path.GetExtension(FileUpload1.FileName);
            sFileType = sFileType.ToLower();

            if (sFileType == ".xls")
            {
                string FilePath= System.Configuration.ConfigurationManager.AppSettings\["FilePath"\].ToString();
                FilePath = FilePath + FileUpload1.FileName;
                FileUpload1.SaveAs(Server.MapPath(FilePath));

Thanks for your reply..... my problem is not related to database....its related to performance & scalability of static classes. code is as follows -

static public class TempExample
{
static public bool GetCombo(object a, out DataSet dsAccountClass, string strClassType)
{

        IDBHelper intfDBHelper = DBClient.GetDBHelper();
        dsAccountClass = new DataSet();
        IDataParameter\[\] arParms = intfDBHelper.CreateDBParamsArray(2);
        arParms\[0\] = intfDBHelper.CreateNewDBParam("ID", SqlDbType.NVarChar, 6);
        arParms\[0\].Value = a.strA;
        arParms\[1\] = intfDBHelper.CreateNewDBParam("ClasificationType", SqlDbType.NVarChar, 1);
        arParms\[1\].Value = strClassType;
        try
        {
            using (IDbConnection connection = DBClient.GetConnection(a.strSystem))
            {
                intfDBHelper.FillDataset(connection, CommandType.StoredProcedure, "p\_GetSpConditionCalssCombo", dsAccountClass, new string\[\] { "dt\_ProductClassID" }, arParms);
            }

            if (dsAccountClass.Tables\[0\].Rows.Count == 0)
                return false;
            return true;
        }
        catch (Exception ex)
        {
            throw DBClientUtils.GetDBErrorMessages(ex, a.strUser);
        }
        finally
        {
            dsAccountClass.Dispose();
        }

    }

}

Multiple user will be accessing this class without creating an object so what will happen if 100 users are trying to access the same method of class at the same time.

Hi All, I am really confused with.....static classes...its harmful or beneficial in terms of scalability. no. of users are accessing one static method of static class.....that performs any operation like data insertion, update, deletion and fetching from database..... my confusion is that...while all users will be calling the same method using class directly then it will maintain the version or all users will be in Q. or something else.... I am eager to know ..... Thanks

Dinesh Sharma

it will return an object ....its ok. but which property will return the number of rows.... I tried the rows property but its not returning all the rows.

Dinesh Sharma

Thanks Parwej The Id here is a table that contains multiple rows like grid so by using all i am getting all the rows ... for this control value is not supported

Dinesh Sharma

Hi I am implementing document.getElementById(ID).all to get all the data (working fine with IE :) ) but unfortunately Firefox 3.0 :( doesn't support this. anybody has done a workaround for this please reply. :doh: Thanks

Dinesh Sharma

Hi I am working on ASP.net application and using AJAX.net. if i am runing my application on firefox then my page_load is being called when I click on button (that calls ajax method ) while with IE its working fine (not loading the page again). is there any work around for this...... Thanks

Dinesh Sharma

my file is on server and m using asp.net 2.0... actually if i am using serverside code then page reloads so i am trying to use [Ajax.AjaxMethod()] but it doesn't work properly..... is there any other way...like ajax or.....

Dinesh Sharma

Thanks for your reply I have already implemented the script and I am getting the updated string....but its not updating my physical file "XMLFile.xml". How can I update the file..... Thanks

Dinesh Sharma

Hi I want to Add/update nodes in xml file using javascript..... is it possible? if yes then HOW.... Thanks

Dinesh Sharma

Thanks for your reply...but are you sure the breaking of functions will not affect the performance (speed)

Dinesh Sharma

The following code will replace the machine.config settings for session state

<sessionState timeout="525600" cookieless="UseCookies" mode="InProc"/>

Dinesh Sharma

whatever the setting you want to override define it in your applcations web.config file.

Hi I have to write some functions so i want to confirm whats better... 1. if i write one function with lot of functionalities For exa.

Function Unit()
{
---- some code

---

---

---

.
.
.
}

2. if I break down this function in multiple functions and the call them inside the function and these function will be written in business layer. For exa.

Function Unit()
{
---- some code

Fun1(arg1,arg2)

Fun2(arg1,arg2)

.
.
.
}

Question 2 - is this a good practice (if not what are the drawbacks) or i must use directly Convert.ToInt16(oData). ****I am calling this at so many places

public static short ConvertToShort(object oData)
{
if (oData.ToString() == "")
{
return 0;
}
else
{
return Convert.ToInt16(oData);
}
}

Thanks

Dinesh Sharma

thanks buddy for your quick reply.........:) but my problem is that i m validating the value (entered by user) onblur. if value is ok then move to next text box else focus remain to same textbox. same condition is with next textbox. but what is happening with me .....before firing the onblur event for tBox1 focus goes to next textbox (tBox2) and then onblur function called for tBox1. but as tBox2 got the focus automatically and my function is setting the focus to tBox1 'coz' of wrong value. so tBox2 also fire the event onblur and it happens continuously............. function Check(Ntxt) { switch(Ntxt.id) { case "tBox1": if(Ntxt.value.length<11) Ntxt.focus(); break; case "tBox2": if(Ntxt.value.length<10) Ntxt.focus(); break; } } calling the function TextBox1.Attributes.Add("onblur", "Check(this)"); TextBox2.Attributes.Add("onblur", "Check(this)"); assume both the textbox's condition is false Thanks

Dinesh Sharma

thanks to pay your attention... my scenario is to validate two textboxes on focus lost if validated then move focus to next box else remain the focus on tBox1.

Dinesh Sharma

Hi I have two text boxes and written the javascript function for both that will be fired onblur event. i put the condition in javascript function function Check(Obj) { if(Obj.value==0) Obj.focus() } and calling as: problem is before calling the onblur event focus goes to second textbox and simultaneouly call the Check function for first textbox that set the focus for tBox1 and so now Check() function calling for tBox2.......and stuck in loop........ please give me any solution:confused:......Thanks
