Datagridview Only Creating New Rows On Top Of The Grid Instead Of At The Bottom?
Mar 18, 2009
I have a databound datagridview.I have disabled automatically adding new rows to the grid. The datagridview is bound to a datatable.In it,I have also set the Protected Overloads Overrides Function ProcessCmdKeyto handle and process the 'Enter' keypress.When the user presses Enter within the Datagridview,I want the grid to add a new single row to the bottom of the grid.I have tried several methods to do so,but the grid always adds the new row to the top of the grid instead of to the bottom.I tried posting this issue in the Windows Forms Data Controls and DataBinding board, but didn't recieve any help there, that's why I'm posting this here instead.The only person to help me there said she couldn't reproduce my issue, even when I supplied her with the exact code I was using.I believe there is more than one way to implement this adding of a new row to a datagridview programatically, and browsing through the various msdn forums, I came across several and tried implementing them all, always with the same result.I don't remember all the various implementations I have tried, but here are my few most recent ones:(This is within a class I created that inherits the datagridview. This custom class was the only place I could specify the ProcessCmdKey function, it doesn't work in an instance of the datagridview instantiated directly onto a form. That is why I'm using the me keyword to refer to the datagridview)#1)
If keyData = Keys.Enter ThenMe.Rows.Insert(Me.RowCount(), 1)Return TrueEnd IfReturn MyBase.ProcessCmdKey(msg, keyData)
#2)If keyData = Keys.Enter ThenMe.Rows.Add()Return TrueEnd IfReturn MyBase.ProcessCmdKey(msg, keyData)#3)If keyData = Keys.Enter ThenDim row As System.Data.DataRow = dt.NewRow()dt.Rows.InsertAt(row, dt.Rows.Count)Return TrueEnd IfReturn MyBase.ProcessCmdKey(msg, keyData)

I am trying to insert an initial line (0) into a datagridview (named params). The program will then read each cell in that row, pass them through a function and return values be placed into the next line (1). This will continue until one of the parameters reaches some set point. The problem that I am having is that when I try to insert a new line, it appears above the initial one and not below it like I would like it to.
Here's my code so far:
Private Sub HurricaneWinds_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim init_xrange() As Double = New Double() {0.0, 0.0, 0.0, 40.0, 0.0}
For i As Integer = 0 To 4
params(i, 0).Value = init_xrange(i)

When I have inserted a row to the "data grid view", it inserts it with no problems, except you cannot see it because it's out of the window's bounds. There are scroll bars that you can use to scroll to the row you had inserted, but, my question is: is there a way that the "data grid view" can scroll to the inserted row?

How do I configure the rowheights so that the top and bottom rows (menu bar and status bar) size to fit the height of their content, and the middle row (main content), fills the remaining available space in the program?I can't fix the height of the top/bottom rows because the height of their content can vary.

Here are my two grids -- they are ExtJs grids however we wrap the declarations in vb.net code:
Dim VehicleOptionsGrid As New Framework.WebControls.Grids.Grid
With VehicleOptionsGrid
.ID = "VehicleOptionsGrid"
.Title = "Vehicle Options"
[code]....
Using javascript, is there anyway I can add a bottom scroll bar to these grids? Doesn't seem like we have a wrapped command to do it...

I have a unbound datagridview for which i want to add a new row at the bottom when a user selects a value in the 2nd column of a 9 column DGV. The issue is that i have a default value (0.00) programmically entered into the last row once this 2nd column value is entered. When i call DGV.rows.add() it places the new row at teh top, but when the user enters or changes the last coulmn value then a new row is added at the bottom. I want my programmically added row to be at the bottom and have not found a way of doing this.
PS. What is the logic behind this different behavior on adding rows?

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

I want to know if it is possible that the data grid view (DGV) rows dont stat at the top of the DGV, but start at the bottom. When I select de DGV it comes by default with the first row at the top, just below the column header, when I add a new row, it comes below the first row. But I want the first row at the bottom. And if I want to add a new row, it will come above the first row.

<VB.Net 2010 + SQL Server 2008 + Linq To Sql>
Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.

I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).
