I have a database with values as shown in the attached image "Image1.jpg". There are multiple other columns not shown on the screenshot (over 30), for the sake of this question we'll say I'm interested in columns called "Col1", "Col2", "Col3" & "Col4".
I was able to get this information automatically filled into a TreeView as shown on attached image "Image2.jpg".
At this point I also want to fill a DataGridView from the same database.
I managed to accomplish this with the following
Private Sub FillDataGrid()
Dim DA As New OleDbDataAdapter
Dim DS As New DataSet
[Code]....
But unfortunately this uses the manual binding of data to the DataGridView, which I'm sorry to say I struggled to "convert" if you like, to using SQL commands and coding to connect a database to DataGridView.
I want to filter a text in all columns in a datagridview. So I use Like % in the filter text. However, I found that the text(strFilter in my code) may contain % sometimes. So it have a syntax error. How can I use filter with like clause when the filter text contains %?
Private Sub PassFilter(ByRef dataTable As DataTable, ByVal strFilter As String) Try Dim dataview As DataView = dataTable.DefaultView
I have a table adapter on the data set which is filled by using filter parameter (UserID Field). the filter column is an integer. if i pass one integer value it process perfectly. ie;[code].....i need to fill the adapter with multiple users, so i tried the following code and it gives an error [code].....it gives the error saying "Conversion failed when converting the nvarchar value '1,2,3,4' to data type int.
I'm looking for a recursive subroutine.I have the dataset from sql-server with in the datasource-table a parent- and a child-column. I made a routine to put the parent-nodes in the tree.The problem starts with the childs over so many levels.I can write it out but it is to much code, I'm sure it can be done more efficient with a recursive subroutine.
The tree will be about 25 levels deep.A few days ago I saw a recursive subroutine to fill the childnodes without the above difficulty to write alle the levels in code.That example I cannot find it any more, but it had a line of code more or less like this here below:
Dim Nodes As TreeNodeCollection = tv.Nodes(A).Nodes
How to fill a TreeView from two related tables (Customers 1 -> Products n)? I have seen the example of microsoft using Northwin Database and I do not understand this, I need something simpler.
I am successful in populating data to a treeview from 3 tables (Constituents, epresentations, Letters) from a sql database. The below code works fine for that
Dim constda As New SqlDataAdapter("SELECT * FROM Constituents", conn) Dim repsda As New SqlDataAdapter("SELECT * FROM Representations", conn) Dim lettsda As New SqlDataAdapter("SELECT * FROM Letters", conn)
I just want to display data of a single column from an oracle table into a datagridview or a listbox for readonly with no requirements to make changes to it. Simply display the information.What is the best way forward... To used DATAADAPTER or DATAREADER.s DATAGRIDVIEW SLOWER TO FILL THAN a LISTBOX.i am using the following code to fill datatgridview but for some odd reasons at time it is slow to display the data. I want to use listbox instead
Dim ds As New DataSet Dim adp As OracleDataAdapter adp = New OracleDataAdapter("select customer_name from customers")
I have a form with a datagridview bound to a database that has recorded who entered data into via the windows user id.I am trying to filter the datagridview to only display records created by the user that is currently logged in.I can get the windows user name with function getusername() which returns a string.
The field that houses the username is "staff_entering_referral" I am doing this but the datagridview does not update or change. bindingsource.filter = "staff_entering_referral = '" & getusername & "'"
I have a DGV to filter and i need the outcome of this as a filter string which i can use to filter my BindingSource:
Try Using connection As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=D:ProjectMWMachineWaleMachineWaleDatabaseMW.mdf;Integrated Security=True;User Instance=True")
How could I have a datagridview on a form that could be tailored by the user having the options of lower/greater than, equals to/not equals to etc on each column?
I'm adding textboxes inside a datagridview to use them to filter the data that is displayed in the grid. Each column has a textbox placed in the header. Everything is fine until the grid has the horizontalscroll visible. The texbox move if the scroll isused but they flicker and if the grid has the rowheader visible the textboxes gets over it. Is there any way to avoid the flicker and a workaround with the rowheader. I don't want to have to hide the rowheader but if there is nothing else that can be done.The class is not finish yet:
Imports System Imports System.Collections.Generic Imports System.ComponentModel
I have it so when the form loads I can double click and the row and bring up the form to edit that row. This works. but if I run a filter on it and then double click it doesn't bring up the selected row but the first row of the grid as if I never had a filter on it. I have 1000 rows, I run the search to filter it and find 5 rows. I click on the last row and it brings up the data from row one of the 1000 rows. Always the top row. Does this have something to do with the bindingsource not having the correct index?
filter using with combobox and display record from datagridview.I stored data in ms-access and display in gridview.i want display record which i select in combo box.
Im creating a filter/search for a datagridview in VB. I have a two comboboxes and one textbox. combobox1 selects a field, combobox 2 selects criteria, textbox is for values. After I select my field and criteria and enter in my value, I hit a Go button and run the following code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Me.TblSpeedStudyBindingSource.Filter = "select * from tblSpeedStudy where " & "'"
[Code].....
I get a syntax error: Missing operand after 'tblSpeedStudy' operator.
I am trying to search a value in 3 access tables. The one of them is the parent and the other to childs.When I search for the value in th parent table everything runs good. When I search for the value in the childs table it seems that I can not find the value, which in reality exists.My code , AturbCustomer (parent), Contact, SAPCustomer (Childs):
SearchString = "'%" & TextBox1.Text & "%'" If ComboBox1.Text = "Customer" Then
I want to add a filter to a datagrid view. What I want to do is add a row in the bottom of the headerwith textboxes in each columnof the grid for use them as filters.
I have a datagridview which filters on a boolean field where it's false. If the user clicks on the field, the line disappears immediately I guess because it no longer satisfies the filter. Is there any way to prevent this?
I have a datagridview which get filled with an sql query like this;
Dim strQuery As String = "SELECT * FROM tablename" SQLConn.ConnectionString = ConnectionString SQLConn.Open()
[Code]....
Now I wanted to add a textbox that works like a filter when someone enters some text in the textbox the ontextchange event add's a LIKE filter for that word on columnname1.
Is something like that possible on the way how I fill my datagridview? On google you'll get some examples only those are with a bounded dataset and that's not working with my datagridview.
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 have a table Called inventory, one of the columns is a checkbox based column called saved where it stores the checked state as the value 1 on the database. On a related form when i load it i want the datagridview to filter to only show the rows where saved has the value of 1.
My problem is once I filter my datagridview I cant seem to be able to update the database. The error I get is Concurrency violation: the Update Command affected 0 of the expected 1 records. Why is it that I cant update after i filter????
