I have a basic web form with about 5 textboxes. One Textbox is "Date1" and the other is "Date2." Is there a way to set the value of Date1 = Date2 after the user enters a value into the Date1 textbox? I'm using Visual Studion and C#. I'm not much of a programmer, so the less technical the better.
View 11 RepliesI have a form with several textboxes. All of these have AutoPostBack="True".
My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,
If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).
If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.
In other words, I want the form to behave in the way that most users would intuitively expect.
I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?
BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.
Dim CurrentTextBox
As
TextBox =
DirectCast(sender,
TextBox)
If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.
Can i easly edit the defualt registration form and add some textboxes to it and make it as a membership page to subcribe?What if i added 2 types of membership, how can i make the form sends the customer an e-mail and tells him what is his new membership type? how to make a form for customer in his own page after login, allows him to edit his info and make a section in this page tells him some alert .
View 2 RepliesI've written a small class .That has a method for adding and subtracting.
My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.

View 8 Repliesi am pretty new to asp.net. i have a little bit of MIS background so i understand the basics of programming. I went ahead and purchased an ASP.NET book and i understand everything. Right now i am creating an application for a doctor. I have created the database behind it but my problem is that i dont know how to INSERT data into the databases from textboxes, radiobuttons, checklists etc i know how to query, modify, delete data but i am stuck on how to insert
In the beginning of the deployment the database will be empty since the doctor wont have any patients. Just to give you an idea how it will look, the first text box will ask for the patient's name, the second for their telephone number etc
I have 10 textboxes on a webform and I would like to use C# to assign separate guids to each.
View 2 RepliesI am developing a mini project in asp.net-c#..how can i visible number of textboxes at runtime to insert records by single click in sql server 2005. for example. If I have assigned 3 subjects in Assign_Subject table then i want 3 textbox at runtime but when we retrieves the subjects from Assign_Subject table we don't know the exact number of subjects to insert students marks into Exam_Result Table....
I need to create textboxes dynamically as per assigned subjects and also I need to read the text entered later (in my case its marks of the student)then 1 Insert button to insert all subjects marks as per single click.
This procedure is call from the page load:

I have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx

Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

I have a page that I'm working on that I trying to do the following with:
1. Name a file upload.txt (with codebehind) every time a file is uploaded with a user pressing a submit button.
2. Validate that the file is a .txt file (again with codebehind)
3. Lastly, once the user presses the submit button, that a sql query is run.
I realize that .xml is the proper way to do this but as I'm new to .net, I want to do this with simply inserting the sql query into the codebehind. Here is my codebehind thus far: [Code]....
Here is the sql query that I want to insert into the codebehind above:

I should also comment that I am writing this in .vb as opposed to .cs and also I am using asp.net 3.5.
I want to insert form data to two table at one button click event.
like
cmd = new SqlCommand("Insert into regis(fname, lname, uname, passwo, repasswo, email, contact, gender, country, pin) values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" + TextBox6.Text + "','" + TextBox7.Text + "','" + D1.Text + "','" + TextBox9.Text + "','" + TextBox8.Text + "')", con);Â Â Â Â Â Â Â Â Â Â Â
I want to store email and contact to another table named details(fieldname=Â contact,email)
How I write query for this. When user click submit button record will saved to both tables.
I have a page with an asp:FormView. When I attempt an insert and it fails I loose the data in the form. ViewState is enabled.
<asp:FormView ID="frm_Person" runat="server" DataKeyNames="Person" DataSourceID="ds_edit_Person" DefaultMode="Insert" ViewStateMode="Enabled">
I am trapping the error on the datasource with
<asp:SqlDataSource ID="ds_edit_Person". oninserted="ds_Edit_Person_Sql_Event" onupdated="ds_Edit_Person_Sql_Event".
(ErrorHandler is just a static lookup function):
protected void ds_Edit_Person_Sql_Event(object sender, SqlDataSourceStatusEventArgs e) {
if (e.Exception != null) {
SqlException sqlex = (SqlException)e.Exception;
lbl_Error.Text = ErrorHandler.TranslateError(sqlex.Number);
e.ExceptionHandled = true;
}
else {
lbl_Error.Text = ErrorHandler.TranslateError(0);
gv_Person.DataBind();
}
}
How do I keep the values in the form?
am having to difficult inserting into a data base using a form, still having some errors.
View 1 RepliesI am writing an insert form (like a survey/questionaire) for a web site to collection data that will call for interactively displaying data from one table after the user enters data for the form; I think it would be like a lookup in standadrd db design, however based on the using it on the web I get stuck on the exact coding requirements.I am currently using Visual Web Designer 2008 Express with the smartdbforms.net tool loaded to create insert, edit & update data to a MSSQL2008 db.
Example:
A Customer logs in to the website and chooses the link to enter data to the database. I have a blank insert mode form for them to fill in the answers to 12 questions (using a smartdbforms.net insert form). The first box is for them to enter their ID#. What I would like is for the first and last name of the user to be displayed on the form (next to the entry box)based on a lookup of the ID# they entered and have it display after they enter it. That data is stored in a differnet table in the SQL2008 db.The db is setup with a insert form data table (empty), and various data info tables that are prefilled to use for validation and edit. I am a windows db designer who is new to the ASP.Net web interfacing commands.
I need to create a form that inserts data into a sql database. I need only a few textboxes but i need the user to select a name from a dropwnlist and it autopopulate the rest of the form with data from the database. Users can update this data and insertthe new data as a new record in the database. I'm not sure how to go about autopopulating the fields tho? I'm using Visual Studio 2010 C#, i'm new to C#.

I need to create a Master Detail detail form to insert data into Access. The form i have to create is very similar to the typical Order/Detail form.
View 3 RepliesI have a database with a 1 to many relationship in SQL Server 2008. I have created a formview in VS2008 to insert records into the child table. However I can't set the foreign key to automatically insert this value. If I manually type in a value the insert works but I need it to pick up the fk ID automatically from the master table. How can I do this?
The master table: tblTopic has ID int auto increment primary key and the child table has ID int auto increment primary key and TopicID int allow duplicates no nulls, foreign key. I have set updates to cascade in the relationship.
My insert statement is INSERT INTO tblTopic (TopicID, Comment, SubmittedBy) VALUES (@TopicID, @Comment,@SubmittedBy). The TopicID keeps throwing the error, this is the foreign key.
This is the first time I have tried to do this, so apologies if it's really obvious but I'm on a bit of learning curve.

why when I selected button select then it show index equal -1 in gridview ?
Before committing the record from the postback of the Create or Edit method in my controller, I validate the values in the form against some business rules in the GetRuleViloations() of this domain object. The following rule example is written in two ways. The 1st one validates against the numeric values in form, the 2nd one validates using the associated object (lookup table in database) description via the foreign key. I would like to use the 2nd method, but during the Create postback the associated object is always null.

I am populating a form trough a query so it will return multiple values, sometimes 5 or 6 or even more.Now when I press submit I need to save each form row in a database.table as a new entry. Other question is I have 3 check-boxes when the submit button is pressed it need to insert the value corresponding to the selected one, how to do that?
Code:
@{
var db = Database.Open("quality");
var selectQueryString = "SELECT * FROM perguntas WHERE chklst_id=@0 ORDER BY id"
var id = UrlData[0];

I've done this using bound controls like Repeaters etc but now I need to display information about a single file for example. SO i will pass the fileid in the querystring, then I need to populate some textboxes, autocomplete textboxes etc. and then save changes. what's the most efficient way of doing this?
