Windows Form With A Datagrid And A Dataset And Some Textboxes?
Jan 16, 2004
I think I fried my brain. Something so easy and I can't figure it out. I have a windows form with a datagrid and a dataset and some textboxes.I have a button that populates the textboxes with the selected row from the datadrid. That works.The user then makes changes to those text boxes.Now I would like to update the dataset with those new values and can not figure it out.If you could please give me some sample code,

[Code] Somewhere my system haves a function that returns a DataSet with the books of a certain subject and all the Authors that wrote such books. I need to show the book's attributes in some textboxes inside a Form. I use a BindingSource to display the ISBN, Name and Subject of the books in a textbox, yet I don't know how to display the author name of the book I am currently viewing in a TextBox, taking into account I already fetched the Author into the DataSet.
Its pretty much the Child/Parent display problem somewhere discussed in the codebank, but kinda backwards, the thing is that I;m navigating through the CHILD records here, not the parent, yet i have all the data needed in my Dataset.

I want to take the values from textboxes on a windows form and then update the values in the sql server database...I want to update only those fields for which a value has been entered by the user and leave the database fields as it is (no change or updation) for which the textboxes are left empty by the user.....I opted for sql command and then i couldn't find out How can I generate the query dynamically for such a situation??? Like I intialize the string by str= " Update Bookings set " and then how i can alter it by considering the textbox values that have been changed....I couldn't find the way...I need shortest and optimized code for this situation....

This must be a common problem, so perhaps someone can point me to a Knowledgebase article. I've got a form that works fine in a completed project. It's a windows form that uses a dataset and tableadapter (which show in the tray below). Now I'm developing a different project that requires a very similar form. I want to "copy" that form into my new project, make some minor changes, and then save it under a new name.

I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters. Here is the code that calls the sub form.
[code]...
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
[code]...
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?

I have a typed dataset with table adapters. I use this method because it makes it easier to design the layout of my DataGridView.The problem is I have added a new table to my dataset. When I go to the "Data Sources" list view, I can see the new table.However, if I add a new DataGridView to my form then attempt to bind it to my new data table, the table will not show up in the list of tables for that dataset.

Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?

I have bind the DataGridview with DB. To add the data from textboxes to DataGrid, I use the foll. code-
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim row0 As String() = {TextBox1.Text, TextBox2.Text, TextBox3.Text}
DataGridView1.Rows.Add(row0)
row0 = Nothing
Catch ex As Exception
[Code]...
Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound
there is no any way to add data to the Gridview if we bound it to the Database.

I want to display dataset records in textboxes instead of GridView. I also want to provide next, previous and search option to navigate between records in the dataset. And I also want to provide update and delete buttons to update and delete the current record that is being displayed.

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?

What im trying to do is, when I click on any row on my datagrid(dgvCompositions), all the cells(16 columns excluding ID column) in that row must be loaded into the 16 textboxes I have (txtB1, txtB2, txtB3....)
So when I click the row, and the entire row is highlighted the text from the cells get loaded into the textboxes.
I know how to pull data or text from specific cells clicked
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
TextBox1.Text = DataGridView1.Item(0, e.RowIndex).Value
End Sub
But the problem I have is that how do I pull all 16 simultaneously and put them into 16 individual text boxes?

I need a way to read an xml file into a datagrid without using a dataset. I realize this is probably the accepted procedure, but it forces me to change a lot of existing code if I do.

I have tried googling so much that I have given up trying to look. I am trying to display a dataset in a wpf datagrid. After that I am going to need to display the individual column value in textboxes. I can then change the value in those textboxes and pressing, say, a commit button, to commit the changes to a database. Here's the code I have so far.
Dim con As New SqlConnection
Dim dbConnString As String
Dim ds As New DataSet

My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:
Public Sub Connect()
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
Dim dr As OleDbDataReader

I have a datagrid that I use to display data from a SQL 2000 table. I am trying to write back any changes the user makes to the datagrid data back to the original table but don't know the proper method to do this.
Here is the code that populates the datagrid:
Dim TheDatabase As System.Data.SqlClient.SqlConnection
Dim ConnectionString As String
Dim cmd3 As New SqlCommand
Dim Adp3 As New SqlDataAdapter
[Code]...
I could use some suggestions on how to code the write back command that will allow the user to change the data in the datagrid and have those changes be written back to my tAdjustment table.
