I've got a datatable in a dataset binding to a datagridview. One of the columns in the datatable is called status, but it is a type string. It can be "0" or "1". On the datagridview, i want to bind it to a checkbox. if checked, it must put a "1" in the datatable and if unchecked, it must put a "0" in.
View 2 RepliesI Have a question about binding (pageID + PermissionID) to a checkbox/ checkboxlist, without using a textbox or any other tool. The thing is, i'm working on something just for exploration is it possible to have multiple checkboxes all bind to a different pageID but all have same permission. (lets say the permission is view-only) So when some checks a checkbox with ID 1, ,5,9,19,56 he gets view permission to those pages. when he uncheckes then they get deleted.
View 1 RepliesI have an DatagridTemplate Column containing an Checkbox which through an converter gets checked when a property on my ItemSource is "J" and unchecked when the property is "N".This works, but now I want the property to be set to "J" if I select the checkbox or "N" when I deselect it.
My Column:
<local:JNConverter x:Key="JNConverter" />

View 4 RepliesI have a MaskedTextBox using the mask "00/00/2�00" to restrict input to a format of XX/XX/20XX, with the Text property bound to MyBindingSource.SomeProperty of type DateTime.
Recently, values with a single-digit month or day recently started displaying incorrectly. I expect that the ToString() method is being called on the value at some point in data binding, and I believe the call is not padding month / day with zeroes.
I tried setting the format type of the MaskedTextBox.Text property to DateTime in the advanced data binding properties, but it didn't help.
How can I apply ToString("MMddyyyy") when converting the DateTime object to a string, before the value is bound to the Text property?
I have a groupbox with quite a few checkboxes. I want a specific textbox to have custom string per checkbox in the text box.

I have a problem involving late binding, and I absolutely cannot for the life of me figure out how to fix it. I have spent hours researching the problem to no avail, so I am turning to stackoverflow as a last resort.The problem is pretty much this: I am creating a grocery list application. I have a class named Item which stores the name, price, quantity, and description of an item on the grocery list. I have a module named ListCollection which defines a Collection of Item objects. I have created an Edit form which will automatically display the currently selected ListCollection item properties, but whenever I attempt to fill the text boxes, it tells me that Option Strict disallows late binding. I COULD take the easy route and disable Option Strict, but I'd prefer to figure out what the problem is so I know for future reference.I shall paste pertinent code here. (Late binding error is in EditItem.vb)

I have tried declaring a String variable and assigning the Item property to that, and I have also tried grabbing the value directly from the List item (not using the Get function), and neither of these made a difference.

I have been successful in using the datasource binding in VB 2008 (drag and drop from datasource to form)My question is that I have date and time fields in an access database. In the database they are fine. I have the date as a long date and the time field as medium time.When these dates are viewed in my vb form, they show as:example (for date of 5/15 and time of 9:00)
Date field: 5/15/2009 12:00:00 AM
Time field: 12/30/1899 9:00:00 AM
I tried to format these field in VB to long date and medium time but it doesn't change. Any suggestions on how to do this?
I have a table on an sql server and am creating a form to manage the records in the table. On the form I have a combobox to navigate between records and am using this code to populate a dataset and the combobox...

Also on the form I have various textboxes to edit the data for each record, and when the combobox selection changes, the data in the textboxes change. I know I can update the selected record when the contents of a textbox changes, but is there a way to bind the textboxes to the current record? What is the perfered best) method of handling this?

i have a datagridview bounded to a bindingsource that's pointing to a datatable created at runtime. In the same form i have a Add New, Save and a Cancel Button,the Add new calls the addNew, the Save Calls the EndEdit and the cancel the CancelEdit. Now the problem, if i fill only some fileds in the new row and call the cancel edit, the row is deleted, but if i fill all fields and i call cancel edit nothing happens.What i want it's, when i press the cancel button even if i put values in all fields the row get deleted.
View 1 RepliesI've read (or the only book that covers ado 3.5) is Murach ADO 3.5 and throughout the book, the author recommends using object binding so that's what I've been doing. However, I had a chance to look at all the codes for our applications at work, and only datatables are used.Was curious as to the difference/pros and cons between binding to an object, and binding to a table. I guess my real question is which one should I be using, datatable or object binding? Is there a definite answer or does it depends on the situation and what I want to do?

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......
I use objectbinding to display client data in a datagridview. The datagridview also contains a counry-column allowing the user to choose the country of the client.Unfortunately, databinding of comboboxcolumn does not seem to work if an own business class is used. Using a simple collection instead works well.Copy the sample code into a new windows project and the programm runs fine. Then comment and uncomment the two lines with "XXX" and the code will fail. Why and does anybody know how to make the sample code work by using the business object class(variable named "newClientListVariable" in the sample)? [code]
