Changing Data Format In DataGridView?
Dec 6, 2010
I am currently reading a table from Access database and displaying it a DataGridView. Here is my
Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= ....db1.mdb"
Dim SQLString As String = "SELECT Cost, Average, FROM expense_summary"
[Code]....
All the files in my access data base are numeric (database cannot be changed) but I need to change the value formats in the table. I want to convert one particular cell in the table to a percent with one decimal and also display the '%' symbol. Similarly, I want to round and display a '$' symbol in another cell. How would I do that? How would I select a specific cell in this table to change?

I have a datagridview populated using a csv file. I have a column named Date. The csv file has mixup of different date formats. So I need the date column in datagridview to be in standard "MM-dd-yyyy" format. I used below code
Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "d"It didnot have any impact.
So I used the below shown code Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "MM-dd-yyyy"Still no effect.

I'm returning a database query into a List object and using that list object to fill the X and Y axes of my chart as seen below. (_runData is a "List(of DatabaseTableName)" style Object filled with the results of my query.
Primary_Chart.Series(0).Points.DataBindXY(_runData, "DateTime", _runData, "UPPER_PRESSURE")
My Datetime field is returning as a Serial Number (i.e. 40116.76111) so I want to format the X Axis to display the field more readably. Enter my problem code.

I have a dgvAssetsSummary which holds data queried from the database, it hold's the AssetType column and Total column, it's grouped by AssetType, giving a summary of all the totals and what assettype they belong to.I'd like the Total column to be formatted so that there are no decimals and with commas, at present each total has four decimal places and no commas, this needs to be able to be read easily by clients. I've tried using the following code to format the column after I query the database, but to no avail.
dgvAssetsSummary.Columns("Total").DefaultCellStyle.Format = "#,#"
how to do this, I've had a bit of a look around but I can't find much. I'm currently looking at a couple of pages from the msdn library about it.

I fetch data from an SQL Express database table named ALARMLOG to a datagridview1. One of the columns of ALARMLOG is "TheTime" which has datetime data type values. This values are in the following format "22/04/2010 13:23:45 PM".When I fetch the data to the datagridview1 I get "22/04/2010 13:23 PM".The problem is that I can't display the seconds in datagridview1. I tried the CORVERT command of SQL in order to convert from datatime to varchar but nothing...

I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?

When I use the code
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I get an error saying that the cursor format may be wrong. It is a .cur which is the standard for cursors. How to rewrite this so when GetAsyncKeyState(1) then the computers cursor will change to the currentcursor.

I have a custom control that includes a DataGridView control. I would like to be able to adjust the heights of the rows on the dgv to fill the custom control on the target form whenever the custom control is resized. I am able to adjust the width of the various columns so that the dgv fills the custom control, but I have not been able to adjust the row heights in a similar way. I have tried the following code in the resize event of the custom control
for i = 0 to dgv.columns.count -1
dgv.columns(i).width = newwidth
next i
[Code]....
This doesn't cause an error, but the code does not change the row height. The column width change works fine.
I am able to change the row height by changing the font size at custom control compile time. I have not tried to change the font size at runtime, since this would not achieve what I am trying to accomplish.
I suspect that my problem is that I have not set one or more of the autoresize flags properly, but I have tried all the combinations I can think of.

I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.

I have a form with a datagridview on it. I would like to use the same grid with two different datasources (not at the same time). If I call the form this datagridview is on with one routine, I want the source to be a list (of Class). If I call it from another routine, I want the source to be a dataview. The problem is once I set the datasource the first time, it keeps that same source even when I try to change it. I'm using this code in the form with the grid:

I can pick either one of these and they work, It just doesn't change if I run it again with the other one.

How do you change the row height of a datagridview in the designer.I can change the header row height or the font size but the height of each data row stays the same. Does this have to be done from within the VB code?

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).

I have a grid bound to a datatable. The grid has two boolean fields. What I want to happen is, when the user checks one field (or perhaps I change that field's value in code), I want to automatically uncheck the other field. I tried the following code, and it gives me the results I'm looking for, but only after the user leaves the row. I want it to happen when the user clicks on the cell.
Private Sub ComparisonGrid_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles ComparisonGrid.CellValueChanged
If e.RowIndex > -1 Then
If e.ColumnIndex = Me.FirstUseColumn.Index Then

I have a DataGridView which is filling from Table in SQL Server Database. One of it's columns is "price".
Type of column in DGV is automatically sets as Decimal.
In some cases I need to write in cells of this column text like "none", instead of price.
How can I do it?
DGV.Item("price", 0).Value = "none"
doesn't work, because of decimal type of a cell.
