I have a dataset that is being generated from an XML file.
This dataset has two tables (User and UserSecurity) - that is related because they both have the same primary key. [i know, the tables should probably be combined, but this is the data that I have to work with][code]...
I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?

so the problem is when i change the combobox3 index the datagridview dosnt change unless i reselect from the combobox2 so what can i do to make the datagridview display the Sql1 when i change the combobox3 index without the need to keep changeing the combobox2 index
I currently have this working already for one of my combo box's, but when i try to use the same code i get this error ''There is no row at position 6.'' . The are 2 fields in the table asset_type_id, asset_type_name', im trying to dispaly the values in a combo box for the field 'asset_type_name.
the code for ' Friend Sub RetrieveCustomerInformation2()' works but the other friend sub throws the error.

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
[cod]....
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.
I am new to VB.NET.I am creating an database windows application in VS2010 and SQL server 2008 express.In one of my form i have a datagrid.My requirement is that i want to display the sum of an column of a DB table and other related data from other tables in the datagrid which is having 4 fields :1.

View 2 RepliesI consider myself a very patient guy with a whole lot of determination to get things working within say, a program i'm working on. However, I feel that I am only wasting precious time that I could be using to actually gain knowledge in something rather than hitting my head against a wall accomplishing nothing. It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it. The program retreives the records, but does not populate these records onto a datagrid.
