I have created a table in my SQL database that has a primary column (Title) and another column named Callsign. How can I access the table row that has a certain title and Callsign using C# in a web page event handler?
Is it possible in to set up an SQL table column to have multiple values? Or would I have to put my values into a new table and link it to the original one?
I have just started using LINQ with VS2008. I have added extra columns to my table, saved the changes, but class ClassName.Designer.CS didn't get updated. What do I have to do to updated the class? Do I have to do it manually, or is there a way to automatically synchronize tables and ClassName.Designer.CS?

I've requirement where user can enter multiple columns like first name, lastname, email, age, sex fields and insert them into database.on my frontend aspx page, i'll be showing a single row initially with 5 text boxes(first name, lastname, email, age, sex) and a button to add more columns. when user clicks on add more, another 5 textboxes will be shown and then i'll be taking 5 + 5 (textbox values) and comma seperate them and need to insert into a table with primary auto increment key ID and the remaining 5 columns(firstname, lastname, email, age, sex). I previously worked on the same requirmeent but with only single column. Now i need to insert for 5 columns, How can i do this? Below is my stored proc which i used for single column insertion.
I'm creating a table in an asp.net code behind dynamically, and I want to have a footer row that only has 2 cells. The first should span all the columns in the table-1. Is there some way other then keeping track of the # of columns in the table manually for me to set the colspan to be # of all the columns in the table-1? Preferably a HTML or CSS solution?
I've the following code which successfully makes an average for all the columns from a table. What I need to do though is ignore certain columns in this equation.
Dim totalNumber as Double = 0 Dim count as Integer = 0 For x = 0 To xyz123.Tables(0).Columns.Count - 1 Dim current as Double = 0 If Double.TryParse(xyz123.Tables(0).Rows(0)(x).ToString(), current) AndAlso current <> 0 Then count += 1 totalNumber += current End If Next Dim averageRating as Double = totalNumber / count
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
i need to extend this so that i can inlcude another column from a different table. so let's say i have a colume in table Price and the column i want to display in datagrid header is cost, how can i do this? there is code backend but could i simply code the below to include this column?
i have a table that has some columns and rows i want this table to have borders that are visible inside it i want every column an row to be closed in borders how can i do that?
Using formview or details view, I want to allow users to both input data into columns (I know how to do that) and add additional columns to the existing table if necessary.
Basically i deal with two tables.i have a table T1 of the following format:id company_name i need to read this data and create a table T2 as followsi wrote the following code. it worked fine for retrieving data and modification but fails to insert the modified data into the 2nd table.the error is, it does not recognise the value for @token
ArrayList dynarr=new ArrayList(); // global variable protected void Button2_Click(object sender, EventArgs e) { int row = 1; int i; string strcmd = null; string Connection = "Data Source=...."; SqlConnection conn = new SqlConnection(Connection); string str = "select company_name from T1 where ID=@ID"; [code]...
I pivoted my gridview with this code. But This code is not mine. Just tested and worked. But i dont know how can i add remove/add buttons to all columns.
1. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?
2. There is a way that without clicking a button we can get the data using objectdatasource, I mean to say that there is no vb.net data in the code behind then how to debug if there is not data in vb.net in code behind.
Iam working on an asp.net application.Recently client come with new requirement. Need a control which is similar to table or like gridview with rows and columns.It should allow user to enter data in the cells. And when the user press tab it should go to next cell and finally if we press enter key, it should validate the data entered in the current row and if data is correct it should create a new empty next row(like entering data manually in an sqlserver table). How can i implement this functionality? Can i use gridview / javascript to implement this functionality.
I'm assuming I need to use a pivot table from what I've found so far. However, every one that I've seen has not had the date setup like I have.
I have a Gridview on my page which I need to be populated like so
Date NCMR
1/1/10-1/31/10 #
2/1/10-2/28/10 #
I want to do this for 10 months... bottom record being the current month (or last month). I would also like the Date to format to January 2010 I used the above date format because that is how it is in the table. Basically, I need to know how to create the pivot table to search the table for 1/*/10, 2/*/10, etc
I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.
Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:
[code]...
"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.
"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?
