Datagridview Bound To A Datatable Setting Its Datasource Property To The Datatable
May 20, 2011I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings

Datagridview Bound To Bindingsource: Displaying Both Old Values And The New Values
Mar 23, 2011I bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,

Although all rows are displayed in the grid, the table represented by the Grid's DataSource does not get updated after changing values in one or more DataGridView columns.

Get Data Bound To A Datagird To A Datatable (VS2003)
Jun 22, 2010I have a form developed using the Dataform wizard (VS 2003). The Form shows Master-Detail data. The details are showen in a Datagrid. The form automatically loads the data in the Form_load event. Now I want to store the data from the datagrid to a datatable. I am using following code to get the details showen in the datagrid into a dataview. The objdsInvoice is the dataset that holds the Invoice And Invoice_Item data.
Dim DV As DataView
Dim tempDT As DataTable
tempDT = objdsInvoice.Tables("INVOICE_ITEM").Copy
[Code].....
Is there any better way to get the datagird values that are currently displayed into a datatable. The datagrid is bound to the details table in the Master-detail type dataset.

View 1 RepliesDateTimePicker Values And SQL Statements?
Jan 9, 2009I'm using this to set the default values of the DTP controls on Form_Load:
Dim dtNow As Date = Now()
dtpStart.Value = dtNow.AddDays(-7)
dtpEnd.Value = dtNow
The problem is, when those values are grabbed from the DTP controls, Access is treating them as wrong datatypes.However, if I manually rechoose the same dates, the SQL statement will work.So, what seems is happening is that it isn't recognizing the initialized values as valid date/time values until I physically choose them.Anyone know a workaround for this or what is really going on and how to resolve this?

Displaying NULL DateTimePicker Values?
Jan 4, 2010I have a database that has null date values in it. When I call the columns from the database with the null datetime values and display it in the datetimepicker text box using a dataset, theres always values in the datetimepicker text box. It sets everything that was in the database with null values to the current date. This is what i have..

How To Get Values Of DateTimePicker Selected Controls
Apr 3, 2010I have two datetimepicker controls on my form:
dtpPickup and dtpReturn
I need a way to ensure that the dtpReturn date selected is after the dtpPickup, and not before. How do I do that? And also, how do I get the values of the datetimepicker selected controls? Also, how can I set the values of the datetimepickers to these two private variables?
Private mdatStart As DateTime
Private mdatEnd As DateTime
It will not let me save them with the Sub for the date time pickers.

Combobox Taking Values From Another Table Than That To Which It Is Bound?
Mar 18, 2010I have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.
