i like to have unique ids for textboxes and hidden filds .is there any property which will give unique id in asp.net ?
something like
<asp:textbox id="ctr001_1" runat="server" uniqueid="textbox" />
what the best way to create text boxes in my loop here so that the IDs are unique instead of just "TextBox" for all of them. I need to add up the Price based on the Price per unit and the Quantity.
My items are loaded from a database so there could be any number of them, so I need to generate the fields on the fly. I was thinking maybe an array of fields could be used like in a form application, or is this not the right way to go?
Here is my code:

I have an easy problem for the experts here...been a few years since my last development work. I have an appl that will track complaints. When an administrator logs in, they go to the main admin.page. From there, they can create a new complaint record-here is where i'm stuck and am looking for a better way. When the admin loads the create.aspx page. i need a way go generate a unique number that i can insert into the db. What is the best way to generate the number...i don't care whether it's numerical or combo, just unique and durning postback the number does not change...the number will be given out as a reference back to the complaint... This seems pretty standard but I can't think of a way that will not duplicate numbers and am looking for best practice with low

Right now I am creating this session with the session key "PhonePart" which is also the name of object I am passing in as a parameter in first method. In subsequent methods, I use the the same name to retreive and clear session value. My problem is, this approach works fine If I instantiate a single object of the class where these methods are defined and using that object call the methods, but when I create another instance of the same class and calls for instance method AddToSession and pass that instance, it overwrites the session value stored by the first instance of the class as the session key is the same that is "PhonePart".
Considering this scenario, is it possible that I somehow grab the name of the object as string in the calling method say "AddToSession" and create a session with that name? If Yes, then I can do the same in subsequent methods and retreive session value and also clear the session specific to that instance name without affecting the other session values stored by other instances.
I'm currently making a site that is supposed to generate search results from a separate assembly, with a gridview that has links to each robot. The links from the gridview are supposed to link to a unique robot details page, as well as display another gridview to all related robots from the set, like this:

how to display unique detail pages. So far, I only have a details page template, but I'm trying to figure out how I can display the data dynamically, depending on which robot was selected from the main search.
Here are my Default.aspx and Details.aspx mark-ups so far:
Default Pastebin
Details Pastebin
And the resulting Default and Details pages:

View 2 Repliesi need code to be able to check if (the date in a textbox) is already (used) in the database or not, if yes then give an error message!!
i am using asp.net 3.5 c#
When a user enters a value I want to check against the other values in the database before allowing the record to be inserted.
It is a nvarchar type column.
Is it best to use a unique constraint (if so, how) or what would be the way to programatically check to make sure this name does not exist. It is not a username, just a name value that will be used in routing.

I would like to give a TextBox in a custom WebPart the ability to AutoComplete on user entry. I am NOT allowed to use the AjaxControlLibrary OR the AjaxControlToolkit. (don't ask... that's just how it is.) Obviously, the TextBox will be instantiated within an UpdatePanel; but how would I go about the rest of this as simply as possible? I would like to be able to pull my list of items for the AutoComplete feature from three potential sources: database, web service, or collection object.
View 4 RepliesI usually find my answers at stackoverflow but this one has bugged me for a couple of days now. I am trying to create a multiline Textbox using ASP.NET MVC with the following code.
<%= Html.TextBox("Body", null, new { TextBoxMode = "MultiLine", Columns = "55px", Rows = "10px" })%>
It just shows up a single line fixed sized textbox. on the other hand
<asp:TextBox runat="server" ID="Body" TextMode="MultiLine" Columns="55" Rows="10"></asp:TextBox>
renders the right view, but in the controller's post method with formCollection named form
form["Body"];
returns a null value.

I am here with a task to generate a unique no of specific length from another unique no.
I want my target unique no of say z length to be generate from combination of a unique no [ that may be a serial no ] of say x length and any secret key of say y length.
I'm creating just simple autocomplete sample.
taking one textbox adding autocomplete extender as
<asp:ScriptManager ID="ScriptManager2" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />

</cc1:AutoCompleteExtender>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
Also creating web services as "WebService.asmx" & code inside this file is that
<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" %>

then in Webservice.cs file i write code as
public class WebService : System.Web.Services.WebService {
MySql.Data.MySqlClient.MySqlCommand cmd = new MySqlCommand();
MySql.Data.MySqlClient.MySqlConnection con = new MySqlConnection();
//MySqlDataAdapter da = new MySqlDataAdapter();
MySqlDataReader dr;
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string[] GetCountryInfo(string prefixText)
{
int count = 10;
string sql = "Select * from tbl_patientmaster Where P_NAME like '" + @prefixText + "%'";
con.ConnectionString = System.Configuration.ConfigurationManager.AppSettings["HMSDBConnectionString"].ToString();
con.Open();
MySql.Data.MySqlClient.MySqlDataAdapter da = new MySql.Data.MySqlClient.MySqlDataAdapter(sql, con);
da.SelectCommand.Parameters.Add("@prefixText", MySql.Data.MySqlClient.MySqlDbType.VarChar, 50).Value = prefixText + "%";
System.Data.DataTable dt = new System.Data.DataTable();
da.Fill(dt);
string[] items = new string[dt.Rows.Count];
int i = 0;

View 1 Repliesi have an application where users are allowed to fill in a form, once saved the form is given a unqiue # in this format: YYYY/MM/DD/### where ### is a 3 digit number, starts at 001, next one would be 002, etc.. the the YYYY/MM/DD is the date the form was saved, so if we had 2 saved today we would get these two:
2011/01/10/001
2011/01/10/002
I just wanted to know how to be sure that those numbers are always unqiue, if two people submit a form at the same time to make sure they are not given the same number? As we had that happen recently now that the application is being used a lot more, two people saved about the same time and once someone clicked save twice while the first save was happening and 2 of the same IDs were generated. Just want to make sure no matter what a unqiue one is always generated. I 'm able to calculate the ###, just wanted to know if there is a way to make sure it's not being used by a process saving right now.
i followed [URL]. it was fine till server side but how would i be applying client side validation for unique field validation scenario on for example say username. i want to have username as unique.
