Oct 11, 2010I have an Access database and I want to view on a datagridview specific rows. For that I used the following :
CasesBindingSource.Filter =
"OfferDate Between #1/1/1997# And #12/31/1997#"
Cases is the table, OfferDate a field of the table wich is DateTime type.
When I use Between operator I get the following error :The expression contains unsupported operator 'Between'.
DataGridView Column Binding Filtering?
Sep 14, 2009I have two database tables in SQL Server Express 2008 with the following layouts.
DATA
-------
id
fundKey
amount
fiscalYear
FUNDS
-------
fundKey
fundDescription[code]....
These two tables are related on fiscalYear and fundKey. So if you were to look at the first line in the DATA table you would get:
1,General,2700,2008
I'm trying to create a front-end for this using VB2008. I thought a DataGridView (DGV) would work well for this. So I create a small app to test out my theory. I put a DGV on it and setup a data source to the DATA table using the designer and it works great. Then I change the fundKey column to be databound to the FUNDS column, looking up the fundDescription based on the fundKey. I also change it to a combobox column because in the future I would like other users to easily change the value. And all of this works well.My problem is in that combobox column, all the fund values are listed as options.So it lists: General, Indirect, General, Sponsored. I would like it to list only the values for the appropriate fiscal year. So if that row is for fiscalYear 2008, the fund options should be General and Indirect. And if it's 2009 the options should be General and Sponsored.What is the best way to do this? I thought about setting up views on the SQL Server side and having two datasets in the app and switching between them.
Error In Binding Data After Filtering
Jan 12, 2009I am trying to make a small application and I have a problem in binding data after filtering them.I use VB 2005 and SQL 2005. The data are shown in datagridview and I bind the selected row to the text boxes of the form. eg.[code]Later on I search the data for some records and at the same time I remove the databinding. When I try to bind them again it does not work because the index is from the whole data and not the filter data.I have fixed the problem in another situation where I had autonumberin as a primary key and I used this as an index. In this case I use platesno as an index and it's not working.

VS 2008 Reading Webpage Source And Filtering String Data?
Oct 28, 2009My program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.
Refresh Datagridview Binding In C#?
Jun 17, 2011I created two tables(FIRSTtable and SECONDtable) in the mysql database and two tables that are related.[code]...
Relations between the two tables using the product_id column with UpdateCascade and DeleteCascade. Both relationships are functioning normally when I try with the sql script. Suppose I delete all product_id in the FIRST table, all existing data in the SECOND table will be deleted.
Both of these tables displayed in datagridview. When I delete all the data in the FIRST table, the all rows in datagridview FIRST table will be deleted, also the data in mysql the FIRST table will be deleted.
I try to open the mysql database, the data are in SECOND Table also deleted, the problem why the view that in the second datagridview, can not be deleted, still keep the previous data? How to refresh datagridview binding in vb.net or C#? [code]...

Binding Source Not Updating
Mar 8, 2011I found the same thread but it has never been answered. So I better to post a new one.
The problem is I added a new column in my table, I have a dataset linked to that table and a source of data of my datagridview.
Now, when I'm going to add a new column into my datagridview, I didn't find the new column which I added recently. Seems that the binding source is not updating whenever an update takes place.
Use Binding Source With A Structure?
Aug 21, 2010I'm writing a order entry system and I'm using structures to pass information around various parts of the program for things like the order header (order date, customer name, etc).
In building the form I discovered that you could use a binding source between form controls and the struct which is great because it means alot less code on a form that will be very busy anyhow. Unfortunatly I'm either doing something wrong, or I've discovered a bug in vb.net because when you fill in a textbox and the binding source fires the setter for that attibute of the struct, it does one of two things. It either: Finds the struct that I assigned to the binding source then creates a new instance of it after it is done thus destroying any changes.Creates a new instance of the struct because it wants to rather than use the one I instructed.
I know this sounds confusing so I'm including a small program that demonstrates the problem I'm having.

Address Cannot Be Found In Binding Source
Jan 25, 2012I'm creating a dataset (AddressDataset) that has 2 datatables - addreess and state.
Addrees: line varchar, state_id number
State: state_id number, state_name varchar
I've created a data relation between state id on these tables. I'm setting up to combo boxes: cboAddreess, and cboState. I'd like cboState to change to the correct value when address changes.

Binding - When Does Control And Source Sync?
Oct 8, 2010First: I have a numericUpDown and a class that are bound.
Me.percent.DataBindings.Clear()Me.percent.DataBindings.Add("Value", options, "percent")When I change the numericUpDown the underlying class seems not to update. I have to click outside the numericUpDown to force validation and force syncing. This is very counterintuitive and will cause problems. How can I make sure the underlying data object gets the new value on valuechange rather than validate?
Second: After I change the numericUpDown I have an option that serializes the underlying data in an xml file. The underlying XML file does not always get the right data. To figure out what is happening I added a button that outputs the values of the underlying data object and it is always getting updated. In other words...the control and the object values always agree. The serialize

Binding Source - Search - Move Next?
Jan 23, 2009I have a child form open (frmProfile) and when I click on the Search button on the Toolbar another form is loaded. On the search form is a few text boxes where the user can input different search functions (First Name, Client ID, Last Name, SSN, Male, Female, etc). Also on the form is one DataGridView.
What I need to do is:
1) After double clicking on a row in the dgv, it sends the clientid to the parent form (frmProfile). I actually have this working but looking for improvement.
2) I would like to then click on the Next button on my toolbar and it go to the next record in line.
At the moment, I only have 1 record that comes in out of 9500. Below is the code from the Search Form and the Profile form.

I have my own toolbar with Add. Delete, Previous,Next etc. I disable some depending on the user so I am not interested in the BindingNavigator.

Binding Source Adding New Method?
Sep 13, 2009I'm currently working on a project where I want to ensure a user does not create a new record based on an ID (such as Customer ID) that already exists.If the record does exist, don;t create the new record and simply move the bidning source to the existing record and display that.What I'm currently doing within the Binding Navigator Add New Click event is checking if there is current data to save and prompting the user if they wish to save the changes before doing anything else.I then set a boolean variable called _NewRecord to true. Then within the lost focus event of the record ID, I have the following code:
Dim itemFound = -1
If _NewRecord Then
itemFound = GroupExists(txtGroupID.Text)[code]....
The code above works well, but I was thinking of doing this using the AddingNew event of the binding source instead to check for an existing record and simply cancel the new record addition then move to the existing record. However, I couldn't find any good examples of how I might do that or how to properly use the AddingNew event.good example of using the AddingNew Method as it looks like it might be useful to know for future projects.
Binding Source And Textbox Not Talking?
Aug 25, 2009Im having some wierd behavior on a bound form in vb.net 2008. I have setup a client form, with another tab that has contacts for that client. the contacts tab has a binding navigator at the bottom, so the user can move amongst the contacts. all fields on that form are bound to a bindingsource called bsContact, using a table adapter called "ContactTableAdapter"
if i have a contact already saved, and want to modify the contact info, the form binding doesn't seem to recognize that i have changed the value of a textbox on that contact.i would think that if a textbox is bound to a bindingsource, then if the value of that textbox changes, the bindingsource would know about it, but it doesn't. The dataset.HasChanges returns false, and my save wont happen. (see code)so, when i hit the movenext on the bindingnavigator, it changes to record 2...i change a value on a textbox...i hit the save button on my form....no update will happen.
Update: I noticed that if i am on the tab with the multiple contacts, and i change a textbox on the form, then i MOVE TO ANOTHER RECORD, then the dataset recognizes that there was a change, and the update happens. Why doesn't the textbox immediately notify the dataset that a change is happening?

May 15, 2009I use the Add new button (of the Binding Navigator) to clear the text boxes for a new record, but then have a Update button on the form where I do an Insert query to SQL, which works because if I refresh the table in SQL the new row is there.However when I then use the Binding Navigator 'move previous' button I get an error saying "Column 'AllowOverbook' does not allow nulls. " - now this is a column that is defined in the database to have 'Allow Nulls' = False, but I do not display this field on my form because in this case it is not required.Instead I have it included on my Insert statement and just set it to '0'
Also when you look at the table every entry in the AllowOverbook column is '0' and there are no NULLS.
