I have 2 web pages. First page has a textbox and a button control.

when I enter test and click on the button , system goes to the second page. And in the second page I want to access the Textbox in the first page. When I try to do this I get the following error.

"Object reference not set to an instance of an object. Following is my code :

Dim txt As New TextBox

' Find the server name on the previous page
txt = CType(Page.PreviousPage.FindControl("TextBox2"), TextBox)
If Not IsNothing(txt) Then
Response.Write("[Name Not available]")
End If

I know I could do this with session, but I want to use the Page.PreviousPage.FindControl. Any help is greatly appreciated

connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly.


I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

Connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly. please verify the installation of the component or download from the URL: go.microsoft.com/fwlink/?linkId=4925

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.

Page.FindControl Causing Null Reference Exception


Hi guys,

I developed a page in VWD 2008 and it works perfectly locally, but when I deployed it on the server every Page.FindControl() call is causing the NullReference Exception "Object reference not set to an instance of an object. " Can anyone help me out? Code is below

                If (CType(Page.FindControl("last_" & i), TextBox).Text.Length > 0) Or (CType(Page.FindControl("first_" & i), TextBox).Text.Length > 0) Or (CType(Page.FindControl("dob_" & i), TextBox).Text.Length > 0) Then

GridView EmptyDataTemplate and FindControl Method


I have 2 textboxes, a dropdownlist and a button in the EmptyDataTemplate of a GridView control and when I click the button I want to get the text from the text boxes and DropDownList put it in the QueryString of a URL i redirect to, but I can't work out why the FindControl method cannot find the controls.  I am using the following code:

Dim ddlNumPpl As DropDownList = GridView1.FindControl("ddlNumPpl")

I get an "Object reference not set to an instance of an object" error though when I try to refer to the SelectedValue property of it though.  I would be very grateful if someone could let me know why the FindControl method can't find the control and what I should do to rectify it.

Many Thanks (in advance),


>>>How to use javascript function in aspx file?



I have a file util.js and there some funtions in same file.

For example functions name are keyUp, keyDown, isNumeric, isAlphaNumeric

I have used these functions in aspx code behind in a textbox to restrict user that he may not be able to input any special character.

Before, I used the code directly in aspx file but I have do it for different textboxes therefore to avoid much coding in aspx file I created util.js and put all code in this file but how to use these particular functions in aspx file I couldn't find the way.

Anyone have idea. Do share with me.

I used the reference like this:


' Font-Names="Verdana" Font-Size="8pt" Onkeyup= "keyUp(event.keyCode)" Onkeydown="return isAlphaNumeric(event.keyCode);" onpaste="return false;">
