Help with the VB.net datagrid

Zone: .NET

Tags: datagrid

Hi,

I have an access database with 5 columns Name, Date, Money, Owing, Total.

when I start the form all the data in the database appears. I want to make it so that if I press a button the name and date show in the datagrid, and another button shows name and money, and the third button is name date owing and total. Is there anyway to do this? Maybe changing the data adapter or something, also I would like to have one more button that shows any name with money over 200 can anyone help with this??

Thanks

Hi balonyJoes90210,
The answer to most of your questions is to use a DataView and to bind the datagrid to the dataview, after restricting your data to what you want.

Yury_Delendik:

Yes. DataGrid has Columns property that is collection of DataGridColumn-s. You can hide any of them using DataGridColumn's Visible property.

DataGrid1.Columns(1).Visible = False ' will hide second column

balonyJoes90210:

Sorry, I guess the real question I was trying to ask was basically how to change the sql code in runtime to change the datagrid, where do I go? Is there a property in the data adapter so that I can change the sql code? I do understand how to populate the data grid, I just don't know how to change the data in it. I built a bunch of queries in my access database, can I use those different ones in run time to change the data in the datagrid? any more help would be great.

every time the button is clicked you can bind your datagrid with the data from the db
you can make a filter of your datatable so you can change the shown records
but if you want to show different information just assign the select command propery of the data adapter to a new sql statement

If I understand your question correctly, the data adapter has 4 property sections in the properties window: DeleteCommand, InsertCommand, SelectCommand, and UpdateCommand. You can expand the SelectCommand section, and change the CommandText property to reflect the new SQL code. Also, you can press the ellipsis button (...) to use Query Builder form.

You can change the datasource in code. That is why I suggested the DataView.
If the underlying table stays the same, then change the RowFilter property of the DataView.
If it does not, then create a new DataSet.

In either case, all you need to do is two lines in code

DataGrid1.Datasource = (The dataset or dataview)
DataGrid1.Refresh

I have a datagrid which displays a single datatable via a dataview (I used the dataview because I did not want the user to add new rows). My problem is that if the value in column 1 changes, I need to set the value in column 2 to 'false'. What event fires if/when the value in a datagrid cell changes?

Thanks

Step1.
Write code to handle the ColumnChanging event for the appropriate table
For Eg:

Private Sub Customers_ColumnChanging(ByVal sender As Object, _
ByVal e As System.Data.DataColumnChangeEventArgs)

If (e.Column.ColumnName.Equals("Column1")) Then
''Set the particular cell value to false
Datagrid1.Item(CurrentRowIndex,1)="False"
End If
End Sub
step2:
''Connect the event handler to the event
''Place the following code within either the form's Load event or its constructor.

AddHandler customersDataSet1.Tables("Customers").ColumnChanging,
Addressof Customers_ColumnChanging

In vb.net i want to be able to break my listbox into columns, so if i where to populate my listbox with names i could have the firstname in column 1 and surname in column 2.
I am using a Access database and adding my items like so

listBox1.items.add(myRecordSet("surname").value)

this works but i want to be able to add forename as well in a second column.

Instead of using listbox my suggetion is to use listview control of the .NET .It allows to add multiple columns..
Stetps:
1. Add a listview control
2. It is having a View property.Change tht property to "Detail"

3.add columns
eg:
Public Sub AddColumns()
' Adding ListView Columns
lstViewResource.Columns.Add("FirstName", 70, HorizontalAlignment.Left)
lstViewResource.Columns.Add("Surname", 100, HorizontalAlignment.Left)
4.Add Items
eg:
Dim str(2) As String
Dim itm As ListViewItem
for i=0 to dataset.Tables("Address").rows.count -1
str(0) = dataset.Tables("Address").Rows(rowindex)(colindex)''firstName
str(1) =dataset.Tables("Address").Rows(rowindex)(colindex)'Surname

itm = New ListViewItem(str)
lstViewResource.Items.Add(itm)
