What code I need to search a whole table (not just one column). I can already search a column but how do I search the whole table for a string .
source1.DataSource = ds.Tables(listboxselect)
Grid.DataSource = source1
source1.Filter = "id = " & searchtxt.Text
I'm trying to filter my access database and when I "search" by name, it works, but when I search by policy number it doesn't seem to work.

I 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'.
The table field [recordaddeddate] is a Date/Time field in my Access database. Usually this field contains a date + time value. For filtering on my datagridview I want to filter on the date portion only. However the following genterates a 'The expression contains an unidentified function call DateValue' error. How can I filter on just the date?
DateSelected = DateValue(Me.AddedDateDateTimePicker.Value)
Me.ConversationTblBindingSource.Filter = "DateValue([recordaddeddate]) = #" & DateSelected & "#"
HIDoes anyone have code for filtering numbers in a binding source?
View 4 RepliesHow can I filter multiple clauses in a binding source. I've tried
Form4.CustomersBindingSource.Filter = "[Last Name] = '" & TextBox1.Text & "'" & "[First Name] = '" & TextBox2.Text & "'"
I've got a datacontext and created a binding source using LINQ to sql but cannot filter said bindingsource. The supportsfilter of the bindingsource is set to false ? why ? I can't find any info to say that I cannot filter a binding source based on a linq query.[code]
View 3 RepliesI 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. What method is used for movenext in code?I could really use some help on this. I have spent way too much time so far but needing to learn the nuts an bolts of 2008
is there any way that i could link/bind multiple binding source to only one binding source navigator?
View 4 RepliesRe DataGridView Sorry don't really have any code - just a whole project. Basically I changed the underlying Access (accdb) Table by adding a new field, The new field shows up in the DataSources section of the Solution Explorer and in the "Edit DataSet with wizard" page but when I attach the binding source to a datagrid view, the new field is not there. I also created a new bindingsource but still not there.I just noticed I've another table where I changed the names to something more meaningful, and the old names are still there and the data for those fields doesn't display in the DataGridView
View 2 RepliesI have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.

I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form
Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)
[code]....
But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.
caseBS.Filter = "CaseId=" & e.Node.Tag.ToString
Do I have to clear the filter in order to find a matter number in some other case??
Can you please explain me and/or show some good tutorials how to do it?It seems pretty complicated because visual studio usually does it all for you and that made me stupid and not to do anything about it.Things I don't know to do in code but I know VS does it for me:

I'm sure there is a good tutorial somewhere on the internet. I'm okay with doing it with designer, but now when I have a situation where I can't use MDI container but tabcontrol.Other solution would be to make a MDI container out of tabcontrol. Is it posible or only other form can be MDI container.

I have a program that needs to generate a random 8 digit ID and check to see if it in the database before adding it to a new row.
At the moment I have the correct code for doing this, but I have it in the event handler Bindingsource.AddingNew. This event handler executes my code and THEN adds the new row. How can I get it to add then new row and THEN execute my code? Is there an event handler I can use to do this?
I 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.
I'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.

I'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.

First: 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

I'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.
