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.
I am a programmer from Uruguay. I have read the other similar questions about my problem, but nobody has given the answer I need. I use VB .net 2005 and its datagridview. I bind it to a dataset which is populated with a table of MySql. And when I sort the numeric columns, it sorts them as string, not numbers. I have tried casting the data to integer in the sql statement, but it doesn`t work. I changed the format of the column of the datagridview to single or long but it didn't worked either. I really can't believe it is happening, it is a so common need! I thingk It should be totally automatic.
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."
Anybody have tried having fixed number (painted) of rows on a datagridview regardless of the number of rows of the datasource??? i.e. datagridview will still show 20 rows even if the the datasource have 8 rows only? like gridlines already painted as is - with/without datasource binded.
with more control over changing values in a data bound DataGridView.On form load, all the data is pulled down from the attached database and fills the gridIf I want to change one of the values in the grid, I can put my mouse cursor in the cell, change the entry and save it back to the database.
I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]
I have a DataGridView object to which I've bound a list of objects (of type Asset) returned from a database query.I'm programming in VB using Visual Studio 2005.I want to grab two copies of the bound object (calling them oldAsset and newAsset) from the selected row in the DataGridView, update newAsset based on input from other controls on the form, and pass both oldAsset and newAsset to a function that will update the appropriate record in the DB.I try to grab the two copies like this:
Dim currentRow As DataGridViewRow = Me.AssetDataGridView.CurrentRow Dim newAsset As Asset newAsset = currentRow.DataBoundItem
[code]....
Opening a watch window on oldAsset and newAsset indicates that the appropriate values are pulled at this point. But when I try to change a property of just newAsset, like
I have a datagridview that is populated from an Oracle 11g DB. What I would like to do is add the values of a column together and display the results in a textbox. What would be the easiest way to do this?
I have a DataGridView that is bound to a DataSet I created from a database table named Contacts. The Contacts table contains a field called StatusId. StatusId is a foreign key to a table called Status. The Status table contains StatusId and StatusName.
I have DataGridView display Customers Details. The DataSource are from DataSet. After the user have created a new customer record and updated the SQL SERVER Table, Instread of refreshing the whole DataGridView I am trying to add new rows with data from the TEXTBOX into the DataGridView and it generated this error message: Rows cannot be programmatically added to DataGridView's row collection when the control is data-bound This is the coding which the error was generated from:
Private Sub FRefreshDataGridViewRow() 'use strmode to determine New or Edit existing record Dim strCell1 As String = CType(Me.txtCustId.Text, String) Dim strCell2 As String = CType(Me.txtCompName.Text, String)
I am currently reading a table from Access database and displaying it a DataGridView. Here is my

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 databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
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 have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code , Dim dtParm As DataTable = MyDataSet.tblParameter Dim dgv As DataGridView = Me.dgvResultNum_DataGrid
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:

There is something strange going on with my datagridview.
I've a data adapter that fills the underlying data table from a database. Then I assign this datatable as datasource to the datagridview Then I add a row to the datagridview and immediately I need to update the table in my database (as soon as user leaves the newly created row).
At this moment I have more rows (+2, not +1) in my datagridview than in the underlying datatable (the new row doesn't exists yet in it so the data adapter .Update method doesn't write anything to the database).
When DataGridView's .RowLeave event fires the undelying datatable is not yet updated. I've a question - is this behavior normal?
If using a datagridview to update a database and the datagridview is bound to a bindingsource which has its datasource as the table to be updated: where dshould you place the tableadapter.update(mydatarow)
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.
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?
I am trying to transfer the entire contents of an unbound datagridview (excluding the headers) to the next row of a bound datagridview. This is what I have so far but I'm not sure if I'm on the right track or not.
vb.net Dim rowcount As Integer = dgv1.Rows.Count dgv2.SelectAll()
I have bound an array of a class with 3 public strings.
When I run the form app and in the form load call I bind the array to the DGV all works fine and the DGV is fully populated. However, if I change an item in the array I had expected it to change in the DGV.. it doesn't. Or rather, it only updates if I click on the cell that should have changed.
I have a datagridview bound to a table adapter. It displays data just fine. Part of this data is a comments field. When a user wishes to edit this I open a seperate form with the data in a a text box. After the user edits this text, how do I update the database / datagridview?
I can update the datagridview cell's value but that doesn't propagate to the database until the focus is removed from the row. I tried BeginEdit and then EndEdit (which should commit) but apparently it needs to move to another row!
I have a form that contains a datagridview control that is bound to a dataset in design mode. This form contains various other textboxes and combobox controls as well and allows users to create and view Work Orders. It also has a Button control ("New W/O"), that when pressed will clear all values from all the controls on the form. My problem is that it's not removing the rows of data in the dgv. The code that I used to try and clear out the dgv is[code]...
How can I reset the dgv to retain it's default column headers but remove all the rows for the selected W/O?
For example; I have a DataGridView bound to a MYSQL Database. There are two string columns "Name" and "Gender". I need to make the "Gender" column a ComboBox where they can select "Male" or "Female".
