Generate 5 digit unique id based on TextBox value using C# and VB.Net

Hi arsh.whd,

Will you please explain your requirement in more details. If possible to explain with example.

Hi there

I want to generate a lets say a supplier ID as ARS001...and so on. This can be done by using code in vb.net and sql server queries. What i want is I want to give a textbox option in the application for the enduser so that they can change the first characters "ARS" to any other whatever they want to use and at the same time I want to limit those characters to 3 or 4 like "ARS" or "ARSH" and then followed by numbers upto 5 digits.

thanks

if want to show value according to u, but don;t want to change in databse. then

Texbox1.Text="ABC"+ur_database_value;

or if want to change in database also, then u need to one extra column in databse to store that value.

Hi arsh.whd,

Check this example. Now please take its reference and correct your code.

HTML

<asp:TextBox runat="server" ID="txtCharacters" />
<asp:Button Text="Get Supplier Id" runat="server" OnClick="Generate" />
<br />
<asp:Label ID="lblSupplierId" runat="server" />

C#

protected void Generate(object sender, EventArgs e)
{
    int value = 1;
    string code = txtCharacters.Text.Trim();
    string supplierId = "";
    if (code.Length == 3)
    {
        supplierId = code + value.ToString().PadLeft(2, '0');
    }
    else if (code.Length == 4)
    {
        supplierId = code + value.ToString().PadLeft(1, '0');
    }
    lblSupplierId.Text = supplierId;
}

VB.Net

Protected Sub Generate(ByVal sender As Object, ByVal e As EventArgs)
    Dim value As Integer = 1
    Dim code As String = txtCharacters.Text.Trim()
    Dim supplierId As String = ""
    If code.Length = 3 Then
        supplierId = code & value.ToString().PadLeft(2, "0"c)
    ElseIf code.Length = 4 Then
        supplierId = code & value.ToString().PadLeft(1, "0"c)
    End If

    lblSupplierId.Text = supplierId
End Sub
