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'.
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.
Here's my code:
If RadioButton3.Checked = True Then
Form3.Show()
Me.Close()
[CODE]...
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 & "'"
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
is there any way that i could link/bind multiple binding source to only one binding source navigator?

View 3 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

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??
Im trying to do bind a dropdown list to a details view but keep getting an error about the dropdown list ID field:
<asp:TemplateField HeaderText="Approval">
<ItemTemplate>
<asp:DropDownList ID="Approved" runat="server" DataValueField="Approved" SelectedValue='<%#Bind("Approved") %>'>
<asp:ListItem Text="Approved" Value="Approved" />
[code]....
The error message as follows:
'Approved' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value
What is the proper way to attach the value of the dropdownlist to my object so that it can be properly created in the database? Most of my searches keep telling me how to bind a dropdownlist to an object data source, but that is not what I need to do. This is a basic drop down list of 2 items that will never change.
I'm working on a VB Winform project using Visual Studio 2008. The form's controls are all bound to a bindng source and a binding navigator which are tied to a dataset class. When the form is displayed, the first record is displayed as well. However, one of the controls (Radio button) is not showing the correct data from the data set. However, if I navigate to the next record and move back to the first, the radio button properly displays the correct information, so it appears the binding source is working the way it is suppose to.

I'm trying to automate a data entry. I have a form with several textbox, combobox, etc.. and i will like to know if there is a way to get a specific row of data from a binding source and duplicate it so I can then simply make the necessary changes to a few columns.

How do i achieve the same in VB.NET (VS2010) in data binding mode?
I am using this code to save my Binding source data to a text file:

I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
I 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.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box

I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that. If I use the data visualizer I can see the name I am after, I cannot figure out the call to extract it

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

i have a simple vb program which i have loaded a data surce access file with it. I have done this using the data scource tab/wizard and then dragged the table on to my form which automatically gives me the functions i need (e.g. next record, save record, add new etc..)This all works as expected and fine within the program but when I open up the access file after - it hasnt done anything to the database/table what so ever - i.e. no changes were applied to it.

View 4 RepliesI'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
I've got lots of textboxes and such bound to a BINDING SOURCE - the datasource of the CASEFILEBS is set like this:
[Code]...
Seems "data saving" is not always being consistently done - sometimes a field change never makes it into the underlying datatable - sometimes certain field changes never make it to the DB. I believe I'm doing something fundamentally wrong that when fixed will clear up some of these issues.
wan to ask about anyone know the code about how to clear all the data inside the data grid view without clear the binding source...
View 1 RepliesI have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.
