Username Exists Check In ViewModel / DomainModel?

Dec 5, 2010

I have ViewModel for Insert/Update/Delete. DI done on controller with Ninject implementing respository patter.

I am little confused. I have UserCreateViewModel bind to Create.aspx once submitted need to check UserName already in DB.

For 1 and 2 I need Constructor DI to call IsUserRegistered method from respository.

1- ViewModel.

2- domain model.

3- service layer. Is it right to add extra layer on to check UserName exists in DB?

4- Someone suggested to use Attribute for that and DI in that.

I want to check if the record is already exists before insert using Ajax ActionLink in Create View. I am getting error 'Object reference not set to an instance of an object.' Here is a code in View :

<div class="editor-label">
<%= Html.LabelFor(model => model.PolicyId) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.PolicyId) %>
<%= Html.ValidationMessageFor(model => model.PolicyId) %>
<em>can not be changed later.</em>
//error occurs here
<%= Ajax.ActionLink("Check", "CheckIfExists", "Life", new { PolicyId = Model.PolicyId }, null)%>
</div>

And Controller action :

public JavaScriptResult CheckIfExists(string PolicyId)

AJAX :: Check Whether A Particular Record Exists In Database Using JQuery

Aug 18, 2015

I 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.

How To Check If A Record Exists

Jul 26, 2010

I tried to illustrate the problem by providing the following instructions, unfortunately the data was deleted and the example failed. It is now working. I have been working through one of Scott Mitchells ASP.NET Application Tutorials Title "Using TemplateFields in the GridView Control"

The URL is ...

The example demonstrates a temporary field being used in different ways, one of which involves dates in a Calender. If the HireDate in the example is deleted or not available the program fails. Providing the date is a valid date it works fine....

SQL Server :: How To Check If A Record Exists In VWD?

Dec 21, 2010

I am very new to this and have watched a lot of the videos. While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do. Here is the latest:

I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)

I also have an ASP web page that allow the user to enter a first name and last name. It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label. If it doesn't exist, then I would like to Insert the info and then again inform the user via label.

SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>

On the code behind, I get lost. (Obviously this doesn't work, but I don't know how to go about getting a results back. Protected Sub bSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSubmit.Click

SqlDataSource1.Select(DataSourceSelectArguments.Empty)
(get a return)
(check return value, if <>0 then
lblResults.Text = "exists!"
else
SqlDataSource1.Insert()
lblResults.Text="added!"
end if)
End Sub

SQL Server :: Check If Value Exists Before Inserting?

Oct 27, 2010

I want to be able to check if a value exists before inserting a new record in the table. I am taking a nvchar value from a textbox and want to compare it to existing values in the table. My codebehind is:

[Code]....

It is also important to filter down by CompanyID which is held in a Profile table. So the value can be equal in records where the CompanyID does not equal the loggedin Profile.CompanyID. So a user with a CompanyID of 2 can have a value in the table for SubType as "laptop" but a user with CompanyID of 3 can still enter "laptop" if there is no match for "laptop" and companyId = 3.
