My problem is this "I have all the tools, VS 2005, 2008, 2010. I have every book, I have SQL server 2005 and 2008" I have all the tools, but I do not know what tool or technology to use when starting out learning all this. I juat do not know what book teaches what I need to do for something like below.
Here is my question:
I created an .ASPX webform that is to "Submit" to a SQL 2005 database. I gave this form to my DBA, and he has made up a Data Model. Now I have to figure out how to write the ASP.NET code so it will submit to the DB. My first issue is not knowing this:
1. "How do I loop through my CheckBox List", and then insert the values checked into a "Database Table" (Each Checkbox value MUST be a seperate row in the table, the DBA does not want a seperate column for each checkbox value)
2. The database is using stored procedures
3. My third issue is this: "I do not know "where" to put the "code". If you do resond to this,
Summary: I just need shown the code on how to "loop through" the CheckBox List on my form, and insert those values into a database table as seperate rows.
In short, I have 3 text box fields on an .aspx page named as follows:-
TextBoxIncident TextBoxDate TextBoxDescription
in addition a sql datasource is on the page which is connected to the incident table with an insert query which allows the data entered into the fields to be inserted into the database...
The Textboxincident and textboxdescription fields allow the user to enter data into them...
the TextBoxDate field is a read only and the code behind file enables the text box to show the current date and time the code im using is shown below...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim TextBoxDate As TextBox TextBoxDate = FormView1.FindControl("TextBoxDate") TextBoxDate.Text = DateTime.Now End Sub
When run in browser the textboxdate field shows the current date and time...and Once the textbox incident and text box description fields have been filled in and the submit button is clicked, the fields should be bound to MS SQL table called Incident. This did work before, however it as suddenly stopped working and now displays the following message to me:-
Arithmetic overflow error converting expression to data type datetime. The statement has been terminated.
I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then lblMsg.Text = "Records Existed" End If
but there are error message. "Object variable or With block variable not set."
I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?
I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.
[URL]
There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
To start with - I'm using VS 2008/.NET 3.5 and working in a company-provided template that leaves me restricted to some/many settings that go beyond the body of the page itself. That said, I need to create a page that will display data from individual cells in a database table that, when lined up would look like a normal sentence. Based on certain criteria I would have certain sections of the sentences hide (ex. if it contains a key phrase or if it's empty).
I've seen a method in which Labels could be used to achieve this effect, where I would assign it the grid coordinates of the cell in a table, but I could never get it to work. I've been successfully connected to the table (LINQDataSource) but still have a blank canvas without this fundamental display technique as that will be all that's in it.
im looking to insert an array of information into a database table
essentially what id like to do is something like this:
objCmd = New OleDb.OleDbCommand("INSERT INTO pluINFO VALUES *", objConn) For j = 0 To 265 objCmd.Parameters.Add( info(j) ) Next
this code gives me a syntax error for the insert statement
is there anyway i can set the insert statement that would allow me to add each element of the array(looping through rather than hardcoding several hundred entries) into the table?
I want to name the headers of the ListView control acording to values of the first rows of a table in the database. This I want to do because the number of columns varies for each cutstomer and also the name of the column.
I am using VB in Visual Studio 2008 and a ASP.NET web page.I have populated a gridview with data aquired from form data. For use in the current session. I am not bound to any database.I would like to pull the headers and also the data one row at a time.How can I do this?I thought I could just do something like myString=Gridview.SelectedRow.Cells.Item(1).Text
I am designing a page that consist one gridview and I am providing datasouce at the run time(code behind) no my problem is that i want to add another column with hyperlink button after click that open a page and can pass some value of related cell onto another page.

as u can see from below aspx code i need values of row of the gridview
1)My gridview last column contains dropdownlist.it contains two values (qualified/disqualifed).on selecting qualified or disqaulified i need to get all the values of the row of gridview....
2)after getting all the values i need to send those values to email...the email should be send to the particular email id of email column,

I have a gridview that have some boundfield and a table inside a tamplatefield. That table have 6 input (hidden) that binds when the page load.
How can I get the values of those 6 input inside the table from server side?
I know how to get the boundfield values , with
Dim selectedRow As GridViewRow = GridDetail.SelectedRow Dim fName As String = selectedRow.Cells(1).Text Dim lName As String = selectedRow.Cells(2).Text Dim Iname As String = selectedRow.Cells(3).Text
i have a gridview with link button and one field called "ID" i have five values....when i click the link button that row value ill show in next page in textboxes ,txtid, txtage, txtsalary,......... if i click that link button that "Id" values should pass to next page using "SESSION" variable in C#.net
generating logic for follwing:An option to add a range of computers based on tag numbers, for instance, user input 800101 and 800110 would add computers SYS800101, SYS800102, SYS800103, SYS 800104, SYS800105, SYS800106, SYS800107, SYS800108, SYS800109, and SYS800110. Currently the app adds a single computer at a time.Here I am using ASP.NET using C# and my backend in active directory. I had made the following code and the problem is when I enter the range like given above only the first computer in entered in the list and does not give me any error.
I have a detailsview, and I was wondering how I can insert value from a textbox instead of a boundfield value. I am able assign value to textbox in code behind.
have a form where I insert record via DetailView control. I have some string fields. For each string field (nvarchar in sql) I have defined the Default Value in the SQL SERVER (2008) as ''. Also I have added to each InsertParameter of the DetailsView a DefaultValue="".Yet still, if the user enters no value for one of the string fields, NULL is inserted into the table.
I am using Stored Procedure as my Insert/Update command in a FormView. The sp returns a value which I will need to use. How do I retrieve the value after doing an insert / update?
I have a GridView with some data in it. Now when I click on the Header text of any of the columns of the GV, the Gridview gets sorted according to the data in that column; however the order in which the data is represented in the database table remains the same. So whenever I am selecting some row in the GridView for performing any action on that row, it selects some different row in the database table.
EG: Say in GridView I have columns A B C with some data and say the corrressponding table in the database which stores these values, has columns A1 B1 C1when I click THE HEADER "A" in the GridView the GridView gets sorted according the data in that column, however this change is not reflected in the table in the database.. it still shows the data in the same order as when entered at the beginning.
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?
I'm joining 2 tables and using the formview. When I insert a record, I need to place the value of the max id + 1 of the second table in a field in the first table so that the tables are linked. I'm not sure where to put the value. I try to put it in the insert command and I've tried the select command but that doesn't work.
Table 1 - Product: ID, ProductNum, Brand, Description Table2 - Brand: ID, BrandName (Brand from Table1 is linked to ID from Table 2) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" DeleteCommand="DELETE FROM [Product] ..." InsertCommand="INSERT INTO [Product] ([productNum], [Brand] VALUES (@productNum, @Brand)" SelectCommand="SELECT Product.ID, Product.Brand, Product.Description, Brand.ID, Brand.BrandName From Product INNER JOIN Brand ON Product.Brand= Brand.ID" UpdateCommand="UPDATE [Product] SET [productNum] = @productNum, [Brand] = @Brand ......"
