I've got grid data and I want to allow the user to filter it.I'm curious what controls or methods you all have used successfully to ask the user for this type of information.I see EXCEL allows you to click a header - ask for a filter - and get arrows in the heading to allow you to see a DISTINCT list with CHECK BOXES.Google Docs spreadsheet does almost the exact same thing.
View 3 RepliesI am looking for a Visual Basic control for my windows application. It's a either a datagridview or listview in VB 2010. The list actually come with the filtering function on the top row. The user is allowed to key in the search key in the respective column and the list will filter at run time. Please refer to the picture below for your reference, the function is in the red box. I found this control in one of the software. Is there any similiar control in the VB 2010 or 3rd party control?
View 3 RepliesI'm reading a binary file into a bindinglist of (t); to be bound to a datagridview.Each line in the file represents a single transaction but I need to consolidate and or filter transactions that meet certain criteriaI know how to do this from a mechanical standpoint (looping the list while adding each item, and adding a new item, or merging the data with an existing item), but I'm looking for a practice, pattern, existing components, or something else that I'm missing (I'm drawing a blank for keywords to search).I don't want to reinvent the wheel if I don't have too. I'm particularly concerned with speed and performance issues with 100k plus records to process in some instances.Currently working with .NET 2.0, but will move to 3.5 if a particularly sexy solution exists.

View 2 RepliesI'm looking to see if anyone has a sample app or has a link to such an app that uses data binding with a grid control and textboxes and is able to insert, change and delete from a datatable which gets updated to a sql server database.I have done an app that has the grid control and the textboxes already and is able to change and delete from the datatable and that action is reflected in the grid control because it has the datatable as the binding source.
The problem I'm having is when the user tries to insert into the datatable I get a concurrency violation error when using the .Update statement to save the changes to the database. This is happening because I don't know exactly how to get those inserts synchronised correcly.I'm sure I'm also doing the processing wrong but here is what I'm doing.When the user clicks an insert button I insert a new row into the datatable. The user now has the ability to enter text into the textboxes. When the user is finished doing that the user can click the save button which issues a .Update statement. That's where the error is displayed

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

View 5 RepliesI am trying to write a thread safe application that contains 3 threads : -
1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering
Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.
The graphing thread then plots the data and waits for more data.
Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).
My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.
Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.
Then thread 2 and 3 can simple dequeue the data.
However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-
Dim GraphArray() as ushort
Dim FFTArray() as ushort
Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?
Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?

I created a query on a Access database, which I would like to show with the datagridview. So, I created a new table adapter with my query, which creates as well the datatable tbl1. Then, the wizard created the datagridview for me, showing the correct data. Now, I would like to filter these rows: I already read it is possible to do it by simply clicking "Add query...", but I would like to do it in a different way. I have some comboboxes, and I would like to use the strings inside them to filter my table tbl1. Is it possible to apply those queries one after the other on my datatable tbl1? I am able to filter only once with:
Me.tbl1TableAdapter.FillBySomething(Me.DataSet.tbl1, params...)
But, if I wanted to filter the result again?

View 3 RepliesI have a database with a Student table and a Class table. There are many students and many classes and each student is a member of a class.I then have a windows form that needs to display a list of student names in a listbox.

DataGridView filtering. I have this data bound to a combobox:
Product Index
Prod1 1,2
Prod2 7,8,9
Prod3 10,11
Actual Table structure is:
Index Product
1 prod1
2 prod1
7 prod2
8 prod2
9 prod2
10 prod2
11 prod3
(Product is the Display Member, Index is the ValueMember)
On the combobox's SelectedIndexChanged event, I'm filtering the DataGridView:
DGVCustomers.DataSource.DefaultView.RowFilter = "indexes like '%" + MyDropDown.SelectedValue + "%'"
If MyDropDown.SelectedValue is "1,2" then any record without either number will not be shown , in addition "7,8,9" will only show customers with that string... etc etc. How can I filter the DGV correctly with the CSV style data? (It's not my data unfortunately!)
I 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.

I am pulling different information from the same file at two different times: 1) The first time, I pull information that is inserted into a combobox. I need to use the combobox as a filter for when I pull the information a second time. 2) I pull different information from the same file, and it is outputted into a datagridview table. I already have a filter in place when the information is pulled the second time, and I was wondering if I could add to that filter or if I have to make another filter? The filter (or filters) will be used to filter the information in the datagridview before it is outputted in a chart.
This is the code for binding the combobox to the information

On the form, I have combobox1, combobox2, datagridview, and a listbox. Basically, combobox2 displays a list of street names. My problem is that once the user selects a street name from combobox2, the listbox should be populated with only the customers' names who lives on that street. How can I go about populating a listbox with just the customer names? Originally, the street names include the house numbers as well. For example, "5100 E Dublin Granville Rd". Fortunately, I figured out how to display ONLY the street names ('E Dublin Granville Rd') and not the full street address to the combobox by adding the following public property below. However, I am still encountering a problem because now the combobox has duplicates of the same street name![code]
