Asp.net - Add New Row To Database Table From Datagrid
Nov 19, 2009
I am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty. I managed to track this back to the text not being passed from my datagrids footer to the sql parameters. I tried using a string first and then passing that to the parameters but they were also empty. I am accessing the control using the following line.
sqlcmd.Parameters.Add("@GoodsDesc", SqlDbType.VarChar).Value = CType(e.Item.FindControl("txtGoodsDesc"), TextBox).Text
The control itself is defined using
<asp:TemplateColumn HeaderText="Goods Descriptions">
<ItemTemplate>
<asp:Label runat="server" ID="lblGoodsDesc" Text='<%# Eval("GoodsDesc")
[Code]....
It's like the text in the footer isnt being tied to the control before I call it.

How can I fit the database table in a datagrid.. Because it is not fit on the database if it has few columns. For example, I have a size(400, 100) datagridview, I want the database table that will display in the datagridview is exact on the datagridview size..

Basically I have a DataGrid on a form that is used to monitor attendance. I do this by making the data types for the relevant fields boolean so that at runtime, they appear as check boxes that the user can tick. If the user ticks this then the table in MySQL saves this as a 1, or if it is left unticked the table saves it as a 0. I then use those values in a mathematical equation to calculate weekly attendance.
My problem, however, is with saving changes to the table itself. Initially I set a primary key which was fine and allowed me to save. However I needed to turn that primary key to a foreign key and when I do that, I am told that I need a primary key. Now I got round that before when I was entering data into a text box and in my SQL query I'd simply put as my value being " & (name of textbox).Text & " but when I am entering data straight onto the datagrid, I am unsure of what to put in my SQL statement.
StudentID (Was primary key but turned it into foreign key)
Name
Surname
Monday

My friend from college told me it's probably because there are multiple records in the database and can't distinguish between the two (as perhaps there's no WHERE clause in that UpdateCommand) but I doubt it as it was working perfectly well with multiple records when StudentID was a primary key.

[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I am writing an import program to import data from an access database to a SQL database.The table structure in the SQL and Access are the exact same with the same field names.I was wondering if there was a quick way to get the data into the SQL table without have to loop through each record?Currently:1. User selects the file2. Use a oledb connection i load the data into a DataAdapter3. Datadapter is bound to the DatagridNormally i would loop through each record in the datagrid and insert it into the table but i was wondering seeing as the column names are the same if i could save the messing about with loops and insert statements using 30 column names.
Code to load the Data is below
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & database & ";Jet OLEDB:Database Password=bekdemir"
