Fill DataGridView Via SQL And Filter Via TreeView
May 12, 2012
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'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.
.tv_Ana.Nodes(A).Nodes(B).Nodes(C).Nodes(D).Nodes(E).Nodes(F).Nodes(G).Nodes(H).Nodes.Add(Trim(sLev_nI + "-" + row_nI("MidCod").ToString()))
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
but it doesn't work yet!

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?

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?

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?
