How do you get row number DataGridView cell? Specifically, if a user has selected a single cell, how can you get that row number? It needs to access a particular cell based on what the user has selected.
I know that the RemoveAt method can be used to remove at the Focus, but you cannot get the row number at focus apparently?
I had the following code :
Dim row As Integer = 0
For row = 0 To pdgvDataGridView.RowCount - 1
pdgvDataGridView.Rows(row).Cells(0).Value = row + 1
Next
it's to add auto number into first column of each row. The codes running well, but after the codes completed, the first column of each row remain empty.
Is it possible to number the rows in DataGridView ( does this property exist)?
When I load the data from the database to DataGridView I want to show thenumbers of row. like this
0
1
2
3

I should move in first position rows that begin with My_Number, but my Datagrid_comb is binding. So I have try this:

OS: windows 7 64-bit /Programming Language: Visual Basic.net on Visual Studio 2010 express edition.I have dataset with 4 tables each one of them is a datasource to a datagridview I want to add a serial number column to the datagridview so I made this
DataGridView1.Columns.Add("serial", "SER.")
For x As Integer = 0 To (ds.Tables("workers").Rows.Count - 1)
DataGridView1("serial", x).Value = (x + 1)
Next
It was working fine untill I added a relationship to the dataset the relationships codes were
Dim relation_WC As New DataRelation("relation_WC", ds.Tables("workers").Columns("id"), ds.Tables("cources_jun").Columns("workerid"))
Dim relation_WV As New DataRelation("relation_WV", ds.Tables("workers").Columns("id"), ds.Tables("vacations_jun").Columns("workerid"))
[code]....
I breaked point the debuging and I found that the serial number column I added is fine and has it's values, but when I reach the line relations.add(the_relation) the serial number column loses it's values and turn into an empty column with no
numbers in it....why this is happening?
Note: I added another relations but the only relations that clear the serial number column are the relations that has a datatable that is a datasource to the datagridview that has the serial number column.
I have the following code. When I use:
For i = 3 To MaxColumnDataGridView
DataGridView.Columns(i).DefaultCellStyle.NullValue = 0
DataGridView.Columns(i).DefaultCellStyle.Format = "N5"
Next
The columns format can't be changed. I cannot change the number format whatever I do.
I'm having problem in my datagridview.I'm using vb 2008 and an access database. When I create a new record for my item the No column (primary key and autonumber in access) always shows a negative number.How can I make that a positive number and it should follow the numbering in the 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 ?

View 10 RepliesI have a DataGridView that is showing some weird numerical data. For example, my under lying datatable of the datagridview has 4.69, but the datagridview shows 4.6899999999999999995. What is weird is it doesn't do it for every cell in the column. For example, my underlying datatable has 2.66 and the datagridview cell shows 2.66, which is correct. I should note that the underlying datatable column that contains the numbers is of floating point data type which comes from the database column and the datagridview column is TextBox. Here is what the values look like in the database, underlying datatable and datagridview.

View 2 RepliesI have a field defined as string for phone number which in my SQL cast to Integer.
Format the column as follows
DataGridView1.Columns("ContactPhone").DefaultCellStyle.Format = "(###) ###-####"
This works as expected for cells with a phone number but for cells without a phone number I get
{}- Which seems like the proper output for what I specified.
is it possible to format cells with no data (no phone number) to show up empty in their cell?

I need to have multiple lines in a cell, so I use DataGridViewTextBoxColumn.DefaultCellStyle.WrapMode =DataGridViewTriState.True. I add columns (datagridviewtextboxcolumn) in designer. Then bound datagridview to a table which has exact the same columns as datagridview. Then I find that datagridview has duplicate columns: the first column is empty (which I guess is added through designer), the second column is filled with data from table. My question is how to correctly allow multi-lines and bound to a table at the same time?

I have a datagridview created for my windows app in 2005 and I'm not sure how to get it to grow and shrink, depending on the number of rows that are displayed. The form contains several filters for the user to use in order to get their desired recordset displayed in the grid and therefore, the size of the grid will be constantly changing. How is this usually handled?

View 5 RepliesI have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property
Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......
The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.
I don't know if I worded this properly, but I have a mdb query that I display in a Datagrid on my form. The first column is TransactionNumber, which is the primary key and a running total (ex. RackingTransactionKey=RackingTransactionKey + 1). What I need to do is when the form is opened, find the highest (last) TransactionNumber from the query or Datagrid and assign it to a variable (RackingTransactionKey), so I can can update it (+1), therefore generating a unique number so I can add data to the query.
