DataGridView Row Selection By VB Program?
Jun 6, 2010
I am using VB 2008. My DataGridView could contain a thousand rows in alphabetic order and I want my users to be able to find a row quickly without them having to scan through many rows. I could provide a row of buttons captioned A to Z or I could provide a search field in a textBox but in either case my program would have to find a particular row and focus on that row. Question one: Does DataGridView have a function that searches for a a particular value in a specified column? I have found no alternative to sequentially searching through the list. Question two: Once I have identified the index to a particular row, how can I make that row become the selected row?
There is so much to DataGridView that somebody should write a book specially about DataGridView. I would buy it.

Is it possible to multi select cells in a DataGridView over several rows?
Example:10 columns, 2 rows
Say I click and hold in row 1, column 5. If I then go down to row 2 column 5. I want column 5 to 10 in row 1 and 1 to 5 in row 2 to be highlight.

Am using vb.net 08 and i have a datagridview with 3 columns. The first column has a button as the columntype with the name "UserName". Now, i want if the user clicks only on the UserName which is the first column, but not the entire row, it should display the value of the UserName column only. If other columns are clicked are apart from the UserName, nothing should display. So there will be a for loop that will itera te through all the rows of the datagridview.
So i have something like this:

I have been looking all over the place trying to figure out how I can programally select a certain Cell in a row. What I am attempting to do is when doing Rowvalidating, and I find that the user has not filled out a column, I do a msgbox, then want to have the cell have the focus, so user can enter in the data. IE, like the way you can cause a text box to have the focus.

I have a vb net program that shows a datagridview which pulls data from a mySQL database. When the user clicks on a row (I am checking for a 'cellclick' event), a text box is filled with data from a hidden column in the datagridview. This works fine and runs without error, BUT...When I use the cursor keys to move the selection up or down, the row highlight changes, but doesn't update the text box. I realise that this is because I am looking for a 'cellclick' event, but I don't know how to look for cursor keys as well.
Please could someone tell me what event I should be looking for to capture input via both mouse click and cursor. I have changed the program so it updates the second dgv on 'selectionchanged' but this crashes at run time with an InvalidCastException.Alternatively, is it possible to stop the user using the cursor keys?

I have a DGV that has a check box in the first column to indicate marked rows. After the user marks the rows they want then the OK button is pressed and the form closes. I need the row data that they marked to be transferred some sort of temp db (preferably in memory - 30 rows or less) so I can insert the data to a tabbed UserControl. I also would like to retain that row data while they are working so in case they want to open the form with the DGV again that the previous marked rows show up.

I've a DataGridView With values. I want to make a button in my forms and when clicking on it I want to change the selection from the current row to the next. To explain more, by clicking my Button I want to simulate the effect of a mouse click on a DataGridview.

I have an inconsistency in behaviour when I try to get the CurrentRow after a row has been selected.
If I select the first row in a DataGridView object using the mouse, the DataGridView1.SelectionChanged event fires, and DataGridView1.CurrentRow is the newly selected row (Row 0).
If I select the first row via code however ie. DataGridView1.CurrentCell = DataGridView.Rows(0).Cells(0) then the DataGridView1.SelectionChanged also fires, but CurrentRow is the old row, not the new row.
In fact CurrentRow doesn't get updated until AFTER the SelectionChanged event has fired if you force the row change in the code, but is updated BEFORE SelectionChanged if you do the row change via the mouse or keyboard.
how to check if its the first row if I've moved to the first row using CurrentCell ?

I am currently working on a net scanner project. I have a class called node. I then create a List(Of node) to create the list of nodes I am going to be scanning.
I have a separate thread that scans the nodes using a simple Do Loop.
I then add the nodes to a DataGridView control:
[Code]...
This seems time consuming if there are a lot of nodes in the list. I figure there has to be a better way to do this, or maybe another data structure I should be using?

how can I make program using vb 2005 that will dropdown the datagridview combobox and display to the datagridview textbox everytime the combobox selection change or when you choose the data.The mousemove is not perfect because when the dropdown combobox length more than the datagridview, the mousemove will not work even other features of datagridview.

I have a datagridview (datagridview1) on my form which onload displays all the records from the bindingsource (bindingsource1) via an sql connection to a table in sql server called "article".
I also have a combobox on the same form which displays the name column from the same "customer" table -
Me.ComboBox1.DataSource = customerTable
Me.ComboBox1.DisplayMember = "custname"
Me.ComboBox1.ValueMember = "custid"
I would like to enable my combobox to filter the datagridview via itsSelectedIndexChanged event . So if custname "xxxone" is selected in the combobox then the datagrid shows only the results for custname "xxxone".
So far I have worked out how to enable the combobox to move to the position in the datagridview depending on which custnameis selected-
Me.myBindingSource.Position = Me.ComboBox1.SelectedIndex
But this method still shows the other titles,it doesnt filter them out, it just points to the selected custname. I cannot find how to filter the datagridview so ONLY the selected custname is shown.
I will be changing the field names, I have used custname and custid just to describe what I am trying to do.

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...
Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick
Try
FlagsGrid.Visible = True

Ive got a datagridview, which the user can put in to 'edit' mode by double clicking. If they then make changes but click to another row, I want to msg asking if they are sure they want to discard then changes. If they say No I want to stop the selection change from being made.
Private Sub DataGridView1_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged

I have a form with a DataGridView and ComboBox, both of which are populated with data from an Excel spreadsheet, the source is unbound. My problem is in repopulating the DataGridView with data from another worksheet in the same Excel file when the user selects the corresponding value from the ComboBox. For example if they were to select January from the ComboBox then the DataGridView would load in and display the data contained on say Sheet2, selecting February would load Sheet 3 and so on. I am running Visual Studio 2008.

My DGV has row BackColors set to various colours based on business logic. When a user selects the row the colour changes to the selected row BackColor thus obscuring the pre-set colour. I would like to preserve the original colour when a row is selected and indicate selection with (perhaps) a bold border around the selected row.
EDIT :To make it clear, this is a WinForms app.

So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Joe
Sean
Larry
Chris
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.
[Code]...
Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?

I'm pretty new to VB.Net programming, but have already been able to figure out many things using this forum, but also via the many other forums on the internet.I'm currently stuck with a question though regarding getting the clicked value in a datagridview comboboxcolumn.When I use _Selected IndexChanged and then check the current cells value, what I get is the value before I clicked the new one in the comboboxcolumn.When I use _CellEditFinished, I can get the new value, but only after I selected another cell, or changed focus to another object.How do I get the new value from a DataGridViews ComboBoxColumn the moment I clicked it in the pulldown menu from the ComboBoxColumn?
