Get Data Bound To A Datagird To A Datatable (VS2003)
Jun 22, 2010
I have a form developed using the Dataform wizard (VS 2003). The Form shows Master-Detail data. The details are showen in a Datagrid. The form automatically loads the data in the Form_load event. Now I want to store the data from the datagrid to a datatable. I am using following code to get the details showen in the datagrid into a dataview. The objdsInvoice is the dataset that holds the Invoice And Invoice_Item data.
Dim DV As DataView
Dim tempDT As DataTable
tempDT = objdsInvoice.Tables("INVOICE_ITEM").Copy
[Code].....
Is there any better way to get the datagird values that are currently displayed into a datatable. The datagrid is bound to the details table in the Master-detail type dataset.

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
I have a listbox bound to a datatable, and controls that are bound to the same datable. As you navigate through the listbox, the controls correctly reflect the selected item, and changes to the controls update the dataset OK as well.Now I'm trying to add a "New" capability to the form. So on the click for "New", I deselect the currently selected item and clear the controls[cod]e...
I have a DataGridView bound to a DataTable. Although all rows are displayed in the grid, the table represented by the Grid's DataSource does not get updated after changing values in one or more DataGridView columns. Both grid and table contain a Primary Key. What am I missing here? Do I need to do something in the RowValidated event?
dgvCriticalContacts.AutoGenerateColumns = False Dim ccRs As DataTable = Common.OpenRecordset("SELECT * FROM PhoneList") dgvCriticalContacts.DataSource = ccRs

I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox. I have the DisplayMember set to FirstName, and obviously only display the First Name of the contact in the ListBox. Is there an easy way to change it so that it displays the First and Last names? I can't change the binding because I need it to get the ID of the record selected.Here's the basis of my code...

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.

We have here visual basic/studio 2003 running in my XP box and I need to install MSXML so I can use MSXML2. I went to the microsoft site and got msxml 4 (code uses that version). I installed it, making sure the SDK was selected to be installed, but when I go back to Project->Add Reference, I do not see it there. Am I missing anything here? My system32 directory looks like this after installing msxml4:
C:WINDOWSsystem32>dir msxml*.* Volume in drive C has no label. Volume Serial Number is D063-14D7

It says I must use only SQL or Access. That is SQLExpress doesn't work. The test connection does work. Trying to do a quick demo project before I spend big bucks. I cannot get my Access 2003 to register so only have 34 uses left.
Dear Friends: I have some files in 1 folder directory that show "XML Configuration File" under type. But none of these files show the extension .config. The directory filesare like C0150,C0150_new,C0200,C0200_new etc. I need to change only 1 attribute of each of these files. I need to write a VS.Net project to do this. I have to send the .exe file(from bin directory of this VS.Net project) to my client and they will just double click the .exe file and it will change that attribute in all the .config files.
The C0150 file looks like this: <?xml version="1.0" encoding="utf-8"?> <configuration>
I have a drop down box that I want bound to "TicketBindingSource - InvoiceStatus". However I want to have the text bound only. The choices I would like to specify from my own list (Invoiced, Needs Invoice...) When the user clicks on a choice I want it to update the database. [code]...
(I'm using VS2005)Instead of using a bindingnavigator, I'm setting one field as a databound combo box with the display member and selected value set to the field.Then the other fields are text boxes and change based on the selected value of the combo box.The problem is that when I run the app, the form won't close.
Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers 2) the lower bound is less than or equal to the upper bound 3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.
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 have some custom code in an extender that can be enabled on textboxes to determine whether or not to display scrollbars based on font, size, and textbox size. It works great, so long as the text box isn't data-bound. Once it is data-bound, I get some weird behavior. The text suddenly selects when the scrollbar is turned on. I am using VS 2005, VB.NET.
