I'm using the filter method of Binding source in VB.net to filter results in a DataGridView based on the text in a search box. However, the idea of this search, is that it shows a row if any of the cells contain the text. So my filter string ends up looking like this:
[Code]...
I have a datagridview1 and search textbox1 on my form On form load I need to fill datagridview1
* with absolute path+filename of certain filetypes like *.jpg,png,gif,bmp
* in a specific directory like Application.StartupPath & "Images"
When user types in search textbox1
* datagridview1 contents need to be continuously filtered to match searchstring
I have a DataGridView that is bound to a datatable. I also have a combo box with sorting items in it. When the user selects a new item in the combo box, the DataBindingSource.filter is changed accordingly.
For the cell and row validation on the DataGridView, I set the row error text accordingly as opposed to displaying a message box.
Occasionally, when switching between items in the combo box, the datagridview gets filled with a bunch of empty rows that all have error messages. It seems it is validating the rows that existed from the previously selected filter against the new filter.
See attached image. I hope I am making myself clear.
I'm having problems with bindingsource. I have a proc used to update a datagridview from a bindingsource. When I run the debugger, the datatable appears to be populated rowcount is 2206 and 7 columns. When the bindingsource.datasource is set, everything looks good. The filter appears to be ok, however, when the datagridview is set to the bindingsource, it's not working. I have it in a try/catch block and an error isn't being raised. When I reference the columns to size them, an error is raised. Below is the snippet of

I am trying to filter the results of a datagridviw using the bindingsource.filter method.

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
I have a datagrid view with some data in it. The first column (0) is called 'Date' and contains the dates I want to work with.What I would like is to be able to filter (only display) the data between a date range selected by the user using 'Datetimepicker1' and 'Datetimepicker2'
This is the code I have. its not right of course, but it may help explain what I'm trying to achieve, I wonder if someone could give me a pointer?

I am using vb.net express version. I have a datagridview which is popuated with data from an access database. I have all the data side working ok with the "Call Date" column set as datetime and sorted in date order assending within my application. I also have a monthviewcalender on the form and wish to filter the datagridview by the date selected in the monthviewcalender to show appointments i may have on that date.I have tried to populate the selected date into a textbox and use the following to filter:
AppointmentsBindingSource.Filter = String.Format("[Call Date] Like '" & TextBoxDate.Text) & "*'"
This causes a error. I have tried many different variants like:
AppointmentsBindingSource.Filter = ("[Call Date] Like '" & MonthCalendar1.SelectionRange.Start) & "*'"
The column is set as datetime in access and is system.datetime in the database explorers properties.
I have 2 problem, on my "addnew" form i need to filter the datagridview using the datetimepicker(Date) and to sort the "EventDate" column ascending(that column is set as text on my MDB that's why it is sorted alphabetically not by month) and 1 problem on my "em" form when i click on the button("View this Event" ) or double click the selected row in the datagrid the "addnew" form will showup with the selected row in datagridview.
And lastly on the "home" form load when there is a event saved today a msgbox will appear(you have event saved today, do you want to view them) if yes "addnew" form will showup with the selected event in the datagridview.
I am pulling data from a SQL server database into a dataset. The date are a DateTime type:
[Code]...
I can see the data in the field reads: 2011-09-09 15:56:29.667. I have tried to convert this by adding convert(varchar(10),DateFrom,103) which results in 09/09/2011 and then Custom Formated the DateTimePicker but still no success.I think I might be going completely off track here so can someone guide me on where I am going wrong here or the best way of doing this
conversion of date
if i used -- Date.parse("28/01/2011")
it gives me error as "String was not recognized as a valid DateTime."
so then i modify above code as -- CDate("28/01/2011").it gives me error as "Cast from string "28/01/2011" to type 'Date' is not valid." I used convert.todatetime also date.parseexact but nothing is working..
I am using access database to store my datas?I have used a datagridview to present the data to the user.I want to give the date filter option to my users.How can i bind the datetimepicker control with my datagridview.one of my datagridviews coloumn is contains date string.

View 4 RepliesI consider myself fairly new to VB.NET, so maybe you could help me here.I have a bindingSource which is bound to a dataset. I have a filter on the bindingsource. My problem is that when I add a new row, with BindingSource.AddNew, even if it does not match the filter criteria, it still isn't filtered out.Could it be that the bindingsource filter never filters out detached rows? If so, what can I do in this situation?

I've been researching it, but can't seem to find any relevent info. I'm trying to filter my BindingSource by first letter in a certain field, in this case, the title field. I can't seem to come up with the correct syntax for constructing the string. The scenario is thus.here is a dropdown combobox with a collection of items such as '0 - 9', 'A', 'B', etc...My filter so far looks like this, at least for the letters, probably have to chain one for the numbers...

I want to use a BindingSource to filter data from a database based on column of type Time but I cannot figure out the syntax for the filter. The filter will select records before or after an entered time. When I use a format of'10:30:00' the complaint is that a TimeSpan and String cannot be compared. Omit the 's and the :s are invalid.

I have a list of customers (over 50k) that I am trying to change the way my users search and interact. Presently, they fill in parts of a first name, last name, home phone field(s) and then click a button and it searches and presents a listview list to the user for selection of the one they are trying to find. Fairly straight forward behind the scenes with a customers object making the call to the sql server on the network and returning customer objects as indicated. I want to add a datagridview control and display all customers and then have a textbox for the user to type their selection into and have the datagridview update accordingly.
I want the filter to be dynamic as the user is typing. What I have so far is the datagrid loaded with data and the text box. I also have a stored procedure that takes a string(the text box) and returns the customers collection object as the "new" datasource. But as you are guessing, that is to many calls to the database over the network. Just not very efficient. Once I have the original collection object, how can I filter it dynamically in memory as the user inputs characters into the textbox.
I am developing a Winform Program in visual basic and I am using Access Tables. I want to use a bindingsource filter to do a search on Stock descriptions. I am using this but it doesn't seem to be working
Me.StockBindingSource.Filter = "ITEMNAME LIKE '%" & SearchTextBox.Text & "%' AND [Supplier1 Price] <> 0 AND [Supplier2 Price] <> 0 AND [Supplier3 Price] <> 0"
What's happening is that I am only seeing products where all 3 suppliers have a price listed that isn't 0. (Products have a zero price when it becomes discontinued or supplier doesn't sell that product but we may have purchasing history against it so it can't be deleted). Therefore we do end up with products where all 3 suppliers have a zero cost. These are the products I don't want this search to return.
I thought I had this sussed until I then wanted to filter between two values or greater than or less than two values. I have searched and searched all over the web for this and I just go round in circles. This is so frustrating why is this so difficult to find something so basic (anyway that is my rant). I have something like this but am totally confused and do not understand what I am doing now: how I get this working in plain English.
Me.BindingSource.Filter = String.Format("DeliveryDate >= #{0:MMM/dd/yyyy}# And DeliveryDate <= #{1:MMM/dd/yyyy}#", dtpStartDelDate.Value.Date, dtpEndDelDate.Value.Date) _
& String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
If I run this with just the date range filter it works fine it is when I add the second filter for the Job ID range I get the following error; {"Syntax error: Missing operand after 'JobID' operator."}
So I it is this line I have the problem with:
String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
I not sure if this can be done with strings, but I have to ask. I have a BindingSource that I want to filter. I want to filter a column that has a data type string. I want to filter for all strings between "Cat" and "Monkey". Also,I would like to do the opposite, filter all strings that are NOT between "Cat" and "Elephant".For example, look at my datasource:
Ant
Cat
Dog
If I filter for strings between Cat and Monkey my filter would return: Cat, Dog, Elephant, Monkey?If I filter for strings NOT between Cat and Monkey my filter would return: Ant, Zebra ?Is this possible?I don't want it to be case sensitive, so I assume you would have to use Option Compare Text.
I am using the following code to filter on a textbox value using the BindingSource.Filter function.I thought this was the right code based on my many searches.
BindingSource1.Filter = "ValueID = '%" & ValueToFilter.Text & "%'"
When do a debug, it shows the correct value which is "432360ac-ac35-4101-8d46-f2cbd5b5dc52.There are spaces in the end of this value and it is exactly the same in the SQL database with the spaces. ValueID is a column in my SQL server. It does not filter the records in my dataset.I tried replacing the ValueToFilter.Text with my actual value as shown above including the space at the end and it filters the records just fine exactly as I want it to. Although I obviously need it to work for multiple values from my SQL server.
I'm using bindingsource.filter to filter data in my datagridview as the query from the datasource (JD Edwards) is being loaded the REQUIRED column is being converted from julian date to georgian date.everything works fine the date is converted and is visible in the datagridview as a short date string.However when i run the filter it wont work unless i manually select a row (it can be any row, but only one row) in the datagridview, then the filter will work.Me.testBindingSource.Filter = "REQUIRED = '" & DateTimePicker1.Text & "'" is the filter. The odd thing is ive used this exact filter before and never had this behavior, i'm stumped.

I've tried replacing the "*" with parenthesis, percentages, and deleting them, but it always gets the same result. What is the correct syntax to use the CONTAINS clause within the .filter query or is there some work around or something that I am missing?
I have a BindingSource that is my DataGridViews data source. I want to filter for all rows where column1 is blank. For example, one row may contain a null value, some rows may contain just white space, and other rows may contain text. How do I show just the rows with text (or numeric, or date) values?
Also, how do I filter for non-blank rows? This would show me all rows that contain a blank cell.
Me.BindingSource.Filter = ?
i have difficulty in doing this inherits bindingsource. I want something like this
for example form 1 filtering data, and display information,
then when go to form 2 from form 1, it should inherit and display information that has been filtered from form 1 to form 2
