Winforms DataGridView Select New Row On Sorted DataGridView?
Nov 16, 2011
Alright I have a DataGridView, where the user can click on the column headers to sort. When they add a new row while a sort is applied, the record isn't created until the moment they validate the row(which they cannot do till they exit the newRow). How can I make the row be selected once it is sorted?The DataGridView is databound.The selection mode for the grid is full row.I'm using VB.NET with SQLite database backend.I suspect I need to use the RowsAdded event, or DataBindingComplete events. The records in question do have a unique GUID attached but it is NOT visible in the DataGridView.

I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:
Imports DiscoveryByte.AddTools.Misc_Tools
Public Class ViewDiscoveryFlashCards
Private DBBindingSource As New BindingSource

I am using a bindingsource to load data in datagridview. Some textboxes, comboboxes and a picture box are binded to the current item of the bindingsource. Note that the image is not being displayed in the datagridview. Only the picturebox in the form display the picture of current row in the datatable. The problem occurs when I follow the steps below:

I have a datagridview named "DG" bound to a datatable. The grid has one column that requires me to determine its value, so the grid has the virtual mode property set to true.When i try to add using the dg.rows.add, i get a message saying 'operation not valid while in virtual mode'.If i set the virtual mode to false and execute the dg.rows.add line i get."Rows cannot be programatically added to the datagrid's rows collection when the control is databound"Ok....i cannot use rows.add when in virtual mode,.....and i cannot use rows.add when i am in data-bound mode.So then next thing i try is ctype(dg.datasource,datatable).rows.add , This gets the row into both the underlying table as well as the into a new row located at the bottom of the grid.
I try this: dg.sort(dg.columns("Row"),ascending) and get this "Operation is not supported when VirtualMode is set to true." i try seting virtual mode to false and get this: "Data-bound DataGridView control can only be sorted on data-bound columns."The column "Row" IS a column in the underlying table.If i click on the column header it sorts correctly.All i want to do is add arow and have it be located in the correct place in the sort order.

What i am trying to do is get the data type of the sorted column that the user selects in order to properly convert a variable. the variable will be used to locate similar values in the dataset that populates the datagrid view.

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow
[Code].....

I have a DataTable in a DataGridView, one of the columns has data that I want sorted. I can click on the column header to sort it and it's fine. The problem is that I don't want that column sorted automatically when some of the data changes in it. I want it sorted only when I click on the header.

I'm calling a webservice using the async method, and catching the response with the completed event. When I first open the form, it all runs fine, however the second time I run the form I get the above error when attempting to sort the data.
Strangely, if I comment out the sorting code, it loads perfectly, and I can manually sort the dgv by clicking on the columns.
Code:Private WithEvents Tempws As ws.wsPrivate ID As Integer
Public Sub New(ByVal ID As Integer)
' This call is required by the Windows Form Designer. InitializeComponent()

I have a WinForms app that has a DGV that's bound to a BindingSource and when the user clicks on the new row line @ the bottom I would like it to fill in two columns values automatically but I'm not sure which event is fired when that row is switches to user editing mode.

I have a Windows Form VS2010 .NET 4 project with a standard DataGridView bound to a datasource on a form.
The grid has a text column that I want to be a point and edit at the character clicked to. Like normal textbox/editors when you click on the character you want to adjust. If possible I would also like to use the UP/DOWN keys to move between rows but would like the cursor to move to the same character position obviously in the same column without selecting the entire text.
I have tried a few things:
DataGridView1.ClearSelection()
DataGridView1.BeginEdit(False)
The BeginEdit just puts the cursor at the end of the text, which means another click to point to the character position for editing.
I know a Commercial grid like DevExpress defaults to editing in which you can click to the correct character position with one click but obviously costs money.
I have tried in the DataGridView1_EditingControlShowing event
If TypeOf e.Control Is System.Windows.Forms.DataGridViewTextBoxEditingControl Then
Dim tb As TextBox = e.Control
tb.SelectionStart = 5
[Code]....
I am just trying to remove the two or three clicks to get to the character position that needs adjustment.

I've used DataAnnotations attribute DisplayName successfully using MVC model binding, and even with WPF/Silverlight model binding and of course it works just fine, but now I'm on a project that I'm forced to use VB.NET 3.5 WinForms.
I have a Linq2Sql model and I created a partial class for one of my classes and included a MetadataType attribute to point to a metadata class. I added a DisplayName attribute to a property in the metadata class. I then bind my datagridview with an IQueryable(Of mydatatype), but the column name in the grid is the Property's name and not the DisplayName.
Am I missing something? Is there something else I need to do to get the datagridview to use the DisplayName?
In my Model class:
Imports System.ComponentModel
Imports System.ComponentModel.DataAnnotations
<MetadataType(GetType(vwREVIEW_ECRMetadata))> _

I'm using a DataGridView in VB.Net in VS 2005. The issue is, when there are rows that exceed the width of the DataGridView, the horizontal scroll bar doesn't appear (the ScrollBars property is set to "Both"), but an ellipsis appears at the end of each row that is too long. I don't want the ellipsis, but the horizontal scroll bar. The vertical scroll bar works as expected when the number of rows exceed the height of the DataGridView.
I have tried setting numerous related properties (changing the AutoSizing property of the DataGridView, Resizability of the Row Template, made sure that no Columns were Frozen) to no avail.

I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.
Public Sub InsertRow(ByVal param1 As String, ByVal param2 As String, ByVal param3 As String)
Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)
[code]....
After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.

I have a DGV I am working on, and I have many columns.
For example I have Columns colIsDayOff (Checkbox), colStartTime(Time), colEndTime(Time)
What I need to do is if when my DGV loads the data if colIsDayOff is checked, then make the value of the Start and End time columns blank, invisible, or something.

Basically I will insert the order number into the Textbox and Click the Button. And I want the row of that order number to be highlighted in datagridview. For Example, I type in AC205 in the textbox and click button and the 3rd row in the above table gets highlighted.

I'm using a search code using a textbox then it lists the record on a datagridview if search is successful. After the search, the user could select the record on the dgv in which later on can be edited or deleted. Edit and delete button is disabled when nothing is selected on the record. What I want to know is how to trigger an event to make those buttons to be enabled when a record is selected. By the way my datagridview is connected to my textboxes. My question goes something like this, but this is totally wrong.
dgvStud_CellClick = Nothing then
btnEdit.enabled = true
btnDelete.enabled = true
End If

Im having a little trouble setting focus on a row in a datagridview. When a user presses the Enter button in my datagrid, a sub is called and the window is closed. Now next time i display the window, the selected cell has moved one row down. This is because when you press enter in a datagridview it jumps to the next line (wich i really dont want it to do). Now then in my forms shown event i placed the code: Datagrid.rows(0).selected = True Now this highligts the first row when the window is displayed, but when you press the down key, it jumps to the third row, because even though the first row is highlighted, its the second row who has focus (because it jumped their after pressing the enter key) How can i set the focus on a specifik row in the datagridview in vb2005?
