View 1 RepliesI'm trying to create a Select Distinct query, but i'm getting stuck with either an empy combobox either a filled combobox that displays all the doubles.or a message "System.Data.DataViewManagerListItemTypeDescriptor"
I have a form (form5) with 1 combobox and 1 datagrid.The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname" The collumn "firm" will have some double firms with people in the other collumns ID Firm Fname Mname Lname1 AA John N West2 AA Jim L East3 BB Harry Sick Long4 CC Barry N Klote etc.I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles. I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i choose and doesn't filter. Is there anyone that can give me a clue on how to solve this.

I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.
View 3 RepliesI would like to select transaction id based from its creation date. All transactions are displayed on form load event on a datagrid. The select function should be executed on 2 datetimepicker (the first should be the start date, the last should be the end date).So there are three controls on a form, 2 datetimepicker and a datagrid. I managed to load all transactions into a datagrid, and managed to select/filter those transaction based on id, but not date.the table is called 'transaction_details', it contains 'transaction_id', 'transaction_date', and few other columns. transaction_id is the primary key.

View 1 RepliesThe problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.

"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True

I have a listbox and a Datagrid, both bound to a database. The listbox contains Names, and the datagrid contains the records of those names. I am tryin to filter out the datagrid, so when i click on one of the names , it will only show those records. Right now when i click on one of the names, it displays that record, but im still seeing the rest of the records from the other names. i know it something like
work_Order.DefaultView.RowFilter = "Name='" & NamesListbox.SelectedItem & "'".
datagridview1.DataSource = work_Order.DefaultView
work_Order = name of the table
Where would i insert the code in? on the form, or on the grid properties?
