I'm trying to create a simple user registration page. I'm using an MS Access database which has some test data in it. What I would like to do is use a CustomValidator on the user name textbox to check if the user name entered already exists in the database. I've read about the possibility of using the ServerValidate event for the CustomValidator control but I can't figure out how to make a connection to the database, query it to check the existing user names, and then fire off the CustomValidator if the user name exists.
View 4 RepliesI am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already. If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database. If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario. I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.

View 7 RepliesI am working on a project in .NET (C#), connected with a database. And I am entering values in database through 'text-box' control, for a part of the project. What I want is to check if the user entering value already exsists in the database and if so, shows error during that time only.
I have searched for any familiar post here, that could solve my query, but didn't get any.
my EXACT objective(if not cleared earlier):-
when the user enter the value in
textbox, automatically an event to
check any duplicate records in
database should occur. And if found,
displays an error message

I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.
I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.
Does that make sense?

View 1 RepliesI have a asp:Button and asp:Textbox on Default.aspx page
Code is as below:
<asp:Button ID="Button1" runat="server" Text="Save" Width="80px" CommandName="Update"
OnClientClick="EnableDdlCompany();saveButtonClick();" CommandArgument="Save" OnClick="btnSave_Click"/>
<asp:TextBox ID="txtBarcodeNumber" runat="server" MaxLength="11" Width="230px"
Text='<%# Bind("BarcodeNo") %>' Display="None"
OnTextChanged="TextChanged" AutoPostBack="true"></asp:TextBox>
On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx
I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:
protected void TextChanged(object sender, EventArgs e) {
TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox;
if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) {
string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character.";
ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);
[Code] ....
Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file
But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.
That's why I want to achieve it using Javascript.
