Datagridview: Adding Multiple Filters?
Sep 13, 2011
I have a windows applicatin built using vb.net 2005 - backend webservice that uses a sql db. I'm working on a form that contains a datagridview that I bound. My pic below to displays the outcome. I have a combination of dropdowns, textboxes, checkboxes, etc in the grid. I now need to add several filters and would like to know, what is the best approach:
1) adding the filters to the header row in the grid.
2) adding the filters outside of the grid as you can see i've started to do from looking at the pic?
I've been reading how it's possible to add them to the grid; but not sure if this is possible to do this when there are controls other than text boxes inside the grid.

I'm designing a form wherein a datagrid is being filtered from numerous controls.
The issue im having is each filter overrides the previous one. Just wondering the best way to approach this problem.
Heres a snippet of my
Private Sub MakeIDComboBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MakeIDComboBox.SelectedIndexChanged
Sheet1BindingSource.Filter = "Make like '" & MakeIDComboBox.SelectedItem & "'"
End Sub

I have a dgv and in it the user can move around column's or resize columns or filter columns. Now there's an issue when the user try's to move the column's around because you have to click on the column and drag it over. But once you click on it, it sorts that column in ascending (or descending) order.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("Make", GetType(String)))

I am currently trying to read an XML file and display the information within a Datagridview. I currently have this working using the below
Dim xmldoc As XmlDocument
Dim xml_nodelist As XmlNodeList
Dim xml_node As XmlNode
xmldoc = New XmlDocument()
xmldoc.Load(openFD.FileName)
[Code] .....
Basically what I want to be able to do is for each <ADVERT> node, so in this case there would be two, I can get the information from both the TITLE and NAME attributes and add them into the Data table which then gets displayed within the data grid view. Currently I can only get the TITLE attribute values to show?

I need to create multiple splitters, then getting that data and adding it into a DataGridView;
AAL1238:KSEA:KORD:1:1492.9:SEA;
AAL782:KSEA:KORD:1:1492.9;
AAL1848:KSEA:KORD:1:1492.9:;
AAL1360:KSEA:KORD:1:1492.9:;
AAL1804:KSEA:KORD:1:1492.9:;
AAL6796:KSEA:KLAX:13:830.785:;
The First Splitter will be a ':', then the next one will be a ;. Per each line up there, I need to add that content into a row into a datagridview, So if you were to look at the datagridview, It would look like that data above exactly, But separated into the correct columns.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

is there any possiblities like this select two conditions in one dataview like
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello'
dv = Childds.Tables("ColumnList").DefaultView()
it has given correct answer but
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello' or customername='hai'
dv = Childds.Tables("ColumnList").DefaultView()
In this case it takes only first one and ignore the second or condition

I'm currently searching a database using filters. The user can use any or all of them, and to achieve this, I have the following
Private Sub GetData()
Dim QueryString As String = "SELECT * FROM Inventory WHERE"
Dim FiltersExist As Boolean = False
'Set Up Connection to Database
[Code] ....
I would like to create this using the query builder instead, but I don't know how to tell it to ignore a parameter if its value is null or an empty string. Another problem with the way I'm doing it now is that if the user has filtered the results, then adds a record, I cannot use the Update method of my TableAdapter, because the datasource of my DGV has changed. Even if I can't achieve what I want with the Query Builder.

I am attemting to read a .txt file database into an xml file and then read the xml file into a DataSet and then bind the dataset to bindingSources and then subsequently bind comboboxes and text boxes to the binding source. I am struggling with how to create bindingsources with different filters. I am not sure if I am even going about this the right way. Perhaps there is a better way. I already have the program working using traditional OLEDB and creating different datatables but I wanted to be able to add and edit my datafile so I decided to convert it to a xml file.

A while back I made a brickbreaker game with out the bricks. Its a picturebox bouncing on the sides of the form and the whole goal is to keep it from hitting the bottom of the form. Now I'm fed up with that, I want to further myself by adding bricks that I can break and keep score. I have something I came up with, but it will only add 1 picturebox.
Dim pb As New PictureBox
Dim locX As Integer = 75
Dim locY As Integer = 100
[Code].....
I did wrap a try/catch inside the do until. My plan is to add one row, then reset my locX, finally move to a different row(locY) and do the same thing.

I am looking to find the best way to do the following: Filter data based on the drop down filters, as long as I am within the same product category (e.g. toys, puzzles, etc...), but in different web forms (product grid and product detail).So if I select toys under $25, I need the filter to the toys in a grid format, but if I click to view the detail I need the filter information so I can filter the related items display.Display certain filters depending on the product category.Right now I believe that if I build a user control and session variables that I should be able to accomplish this.
EDIT: Right now I am using the page_load event to update the data and would like to avoid AJAX for right now.

I have a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.
Case cboQty.SelectedItem = 3
Try

When I execute this query, it works fine for the first record but rest of the records show null value when I know there are records present. SQL pros take a look if there is a problem with my syntax.
