The following code was taken from a javascript script. What it's (supposedly) doing is assigning properties to the line item. A name, a relations array, rounds array (which they lost in), total wins, three tiebreaker scores, and if they had a bye. (This is for a swiss pairing algorithm.)[code]I want to do something like this in Visual Basic. I'm pulling data from a table using a OleDBReader. I want to give each item that is pulled a set of these properties. Then by some means changing them.
When I am scrolling datagrid after selecting one row I am getting error as "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll" on line :
I am using combobox to populate values from a table, 'Suppliers'. I put this combobox in a form wherein the order details are filled up. This column 'Supplier' is a Foreign Key and set to NotNull in the order detail table. Selecting the first available entry on the combobox gives error 'SupplierID cant be Null' . Selecting the 2nd value is OK, first choosing 2nd and coming back to 1 is also OK. This error comes up when trying to update the database.Even with the first value, the combobox is having a text. I would like to know why the error.

I have a datagrid and load data from a database in and can't find thesolution for a couple of propblems..
1) The columns from the DB is loaded in to the datagrid but the width of each column is very small and needs resizing to view all data everytime it loads. Can I programmically make the colums show wider annd fill the datagrid?
2) I load the columns using SELECT col1,col2,col3 from table; then load that in to the datagrid. col1 is a primary key so has to be loaded as I perform an update of edited data at the end. Can I somehow hide col1 so it does not show in the datagrid?
I have some questions formating my datagrid and its columns but unfortunately unsuccessfully. How to change the alignment of a DataGridViewTextBoxColumn? I could only set the alignment of the whole datagrid. I tried to do this by code but it didn't do anything: datagridOnlineStores.Columns("osowner").DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight I tried defaultcellstyle but it doesn't do anything then is there any way I could change the color of the border of the whole datagrid because it's black I don't like it.

I would like to add the properties "visible" and "enabled" to the Items object of a combobox in VB .Net so that I can hide or disable individual line items of the combobox.

Now, I would like to override the custombox.Items object with my custom one.

I am just trying to put an item into a datagrid from another datagrid.
So I got code like this which takes the right item but puts it into the wrong place. It is suppose to put it into Rows(0).Cells.Item(3) but it puts it into item(2) as it caunts from 0 to 3. If i try to put it into Rows(0).Cells.Item(4) I get an error - indexOutofRange.
We have an application with an mdicontainer form which has a menustrip with many toolstripmenuitems. Each of these toolstripmenuitems has dropdown items. We want to be able to set the Visible properties of these dropdown items to true and false in various situations. We are able to do this e.g, mnuFileOpen.visible = True and it does make the menu item visible.
So Let me explain the situation, I have a Mainpage Form with a DataGrid Object on it. I have a Create Post Form and I want to use the create post form to also edit a post. Now only individuals who posted a specific post can edit it. I have all the validation code in to check the user etc. I used a simple boolean and then in the create post form created two subroutines, Newpost and Editpost. I have the New Post working perfectly, but i can't get the edit post to work.
Dim startdate As DateTime = Departdate.Value.Date Dim enddate As DateTime = returndate.Value.Date MainPage.SelectedPost = DirectCast(PostBindingSource.Current, DataRowView)
I'm trying to create a Select Distinct query, but i'm getting stuck with either an empy combobox either a filled combobox that displays all the doubles.or a message "System.Data.DataViewManagerListItemTypeDescriptor"
I have a form (form5) with 1 combobox and 1 datagrid.The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname" The collumn "firm" will have some double firms with people in the other collumns ID Firm Fname Mname Lname1 AA John N West2 AA Jim L East3 BB Harry Sick Long4 CC Barry N Klote etc.I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles. I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i choose and doesn't filter. Is there anyone that can give me a clue on how to solve this.

I am working on a bound DataGrid that displays data from a database. I'm using Silverlight 5 if that helps. Currently all the data is stored in a Dictionary within the my entity object. Using the Property[Key] syntax for the binding path binds properly for display purposes. But the column acts like it is readonly when trying to change a column value in runtime.
Public Class Entity Public Property Attributes As New Dictionary(Of String, Object) End Class

My only thought right now is to store the column values in ordered lists and display them using an index rather than key. But I would really like to know why the key isn't working.
How can you color a single item in a windows datagrid (Windows datagrid 2.0 for Visual Studio 2005)? I tried the overrides paint function but it is very memory intensive for it hits the function each time you move from one cell to another.
i have an database and i have a table there name ad "product_order" i have created a form like attached picture..i want o view all of items in datagrid view where customer_id ( a column of database table) = label value of your id and when i will click to view this form this form will load automatically..
Public Class Form8 Private Sub Form8_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub
I have a listbox and a Datagrid, both bound to a database. The listbox contains Names, and the datagrid contains the records of those names. I am tryin to filter out the datagrid, so when i click on one of the names , it will only show those records. Right now when i click on one of the names, it displays that record, but im still seeing the rest of the records from the other names. i know it something like
work_Order.DefaultView.RowFilter = "Name='" & NamesListbox.SelectedItem & "'". datagridview1.DataSource = work_Order.DefaultView work_Order = name of the table
Where would i insert the code in? on the form, or on the grid properties?
I'm having an issue wherein after I run a search filtering a datagrid, the corresponding datadetails will not update anymore when a new item is selected in the datagrid.I would like it so after clicking an item in the datagrid, the details update automatically.
[URL] The problem is, after running a search (or hitting 'show all') the label/details no longer change when selecting a new item in the datagrid.[URL]
Private Sub Sheet1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Me.Validate() Me.Sheet1BindingSource.EndEdit()
[code]....
To clarify, the search itself filters the datagrid perfectly as intended....it just seems to stop the details from updating when new items are selected which is my problem.
I am trying to load contents of an Excel file in a datagrid. The data in the Excel file is arranged in rows and columns. Every column has a column header. Now here is the anomaly. For some reason when I put a less than sign (<) before some of the values in the last column, the values become blank before they are loaded into the data grid. This behavior is not observed when the less than sign is put into the other columns. More strangely the values are retained in the datagrid even if the the < is put before the values of the first few rows of the last columns within the Excel file. I used the following code in loading data into the Excel file:
Dim con As OleDbConnection Dim da As OleDbDataAdapter Dim ds As New DataSet
