With a two column Datagridview, first column with a number in it, and second column with nonwrap text. When the datagridview width is less than the width of the data in the two columns, the only way I can get a horizontal scrollbar to show is with the width set for both columns. If I then try to scroll down the rows using the down arrow, the grid jumps to show only the second column. I have tried various settings for the columns - fill - fillweight - autosize etc.
I found one solution, setting the first column to frozen in the key down event and then setting it back in the key up event but the scrollbar does flicker and I am sure this is not the correct way to do this.
The user needs to scroll down the rows and be able see the first column whilst doing this and then if necessary scroll right to read any text not visible.
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click 'Function declarations

how can i move the cursor of the datagridview on the selected rows on datagridview.
i used this code and it highlight the rows which matches to txtSearch but the cursor did not move in the selected rows.
Code: For x As Integer = 0 To Me.Datagrid.Rows.Count - 1 If UCase(Me.Datagrid.Item(1, x).Value.ToString) = Trim(Me.txtSearch.Text) Then Me.Datagrid.Rows(i).Selected = True
I have been searching all over the internet for the answer to my problem; How do I move an object according to the arrow keys pressed? I have this code;[code...]
It builds all right, but nothing happens. I have the KeyPreview on, but it still doesn't do anything.
Ok well just started to learn Vb 2008 and im trying to make an image move using the arrow keys..im trying to make a little game just for practicing and im having trouble getting my sprite to move.
Is there any way you can move a panel using the arrow keys during runtime?and is tehre a way of popping random objects in a game. Like you have this spaceship moving and your "Alien foes" or whatever attacks you. So you want them to pop up randomnly every few seconds or so. How?
I am trying to move a Rectangle Shape using the arrow keys and i have done multiple codes and none of them work. Can anyone help me with the coding.[code]also I am not sure if the code goes in Form1_KeyDown or RectangleShape1_KeyDown
I need to be able to move it up with the up arrow key, down with the down arrow key, left with the left arrow key, and right with the right arrow key.I know my "Player" works by the way:
Private Sub PlayerPic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayerPic.Click MsgBox("test")
there is this picture on the form How would you make arrow keys move the object around the screen?Also how would you make buttons correspond to arrow keys?
I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
When I set rowheadersvisible to true and run the program, the little arrow appears on the left of the datagridview and a cell is highlighted. (Accessible role is none.)
I want to detect up,down arrow keys while in edit mode of datagrid view i use the code below but it is not working?
Public Overridable Function EditingControlWantsInputKey(ByVal keyData As System.Windows.Forms.Keys, ByVal dataGridViewWantsInputKey As Boolean) As Boolean Select Case keyData And Keys.KeyCode
[code]....
Both case arrow keys are not detected. please tell how to detect
how to add Rows programmatically to the DataGridView's rows collection when the control is data-bound? here is my code but i got error as "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound? "
I want to move a selected item up and down on a listview.I thought by getting the index and -1 or +1 would work .But can't find the code to define the index of a row.
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2 Column3 Column4 1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:
[code]...
There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
In VB.NET 2008 I've two forms 1 & 2 containing two datagridviews connected to two data source 'ACCESS 2007 tables' Now I want to select multiple rows from one datagridview (form1) & transferring these to another empty datagridview (form2) with a button_click.
I have 2 forms, each one with a datagridview.I want to transfer all the DataGridView Rows from From2 to another DataGridView of Form1. but it's not possible.
So I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
