am trying to calculate the values in rows in column 6 based on values of column 5. Bellow is the the code I am using I get a run time error about the string not formatted properly
[Code]...
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

Datagrid property like AllowUserToAddRows and AllowUserToDeleteRows is already set to true.I am using above code on lost focus event of one of text box.
When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]
View 1 RepliesI have a Datagridview with a bound datatable in it. Then I add a check box column to it.

I'm working on VB .NET 2008.
Target: Bind dynamic datasource in a cell of a Windows.Forms.DataGridView depending on the selection in previous column. The grid must have 7 columns. If the selection on comboboxcolumn 2 or 4 is done, the datasource of comboboxcolumns 3 and 5 mus change using a query with previous selection as parameter.
In a first try to develop this functionality i've tried to use Telerik.WinControls.UI.RadGridView control. I've created a customized celltemplate with a combobox in order to have different datasource for each cell on the same column. All worked fine but seems to be some kind of bug in RadGridView, because when the combobox is presenting the list, after selection the list continued showing, doesn't dissapears as expected.
Ok, after several days of fight with RadGridView, I give up, and I tried to use same strategy but using Windows.Forms.DataGridView. I've created two classes one inherited from DataGridViewComboboxCell and other from ComboBoxColumn, in order to insert my own combbox or have the chance to have access directly to the combobox values. But the combobox showed is the default combobox not my own combobox.
how can I create a custom comboboxcell but using my own combo, and having access from outside to this combo?

Im looking to add some information to a table in VB.net.The table needs 2 columns and a number of rows;1 Column needs to have numbers ranging from 1 onwards, basically representing their row number. And 1 more column which just displays any text when a button is pressed.
Each time the button is presed i need the text to go onto a new row.Ive heard alot about a DataGrid, but everything relating to this seems to be based with SQL and I was wondering if there is a differnet tool which would be simpler to use?

I need to redraw a button in a button column in a DataGridView. Nothing to complicated other than I do not want the width to be as wide as the column width. To do so I am assuming that I have to create a custom button column object which inherits from the ButtonColum. Then I am assuming that I have to over-ride the Draw of the buttton itself.

In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?

I am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
