Xml To Datagrid Without Dataset?
Jan 21, 2012I need a way to read an xml file into a datagrid without using a dataset. I realize this is probably the accepted procedure, but it forces me to change a lot of existing code if I do.

Display Dataset In Datagrid?
Mar 15, 2012I have tried googling so much that I have given up trying to look. I am trying to display a dataset in a wpf datagrid. After that I am going to need to display the individual column value in textboxes. I can then change the value in those textboxes and pressing, say, a commit button, to commit the changes to a database. Here's the code I have so far.
Dim con As New SqlConnection
Dim dbConnString As String
Dim ds As New DataSet

Export From Dataset But Not A Datagrid

View 3 RepliesPopulate Datagrid From Dataset WPF
Jan 6, 2011My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:

Updating A Dataset From A Datagrid?
Dec 20, 2010I have a datagrid that I use to display data from a SQL 2000 table. I am trying to write back any changes the user makes to the datagrid data back to the original table but don't know the proper method to do this.
Here is the code that populates the datagrid:
Dim TheDatabase As System.Data.SqlClient.SqlConnection
Dim ConnectionString As String
Dim cmd3 As New SqlCommand
Dim Adp3 As New SqlDataAdapter
[Code]...
I could use some suggestions on how to code the write back command that will allow the user to change the data in the datagrid and have those changes be written back to my tAdjustment table.
Clearing Datagrid Or The Dataset Bound To It?
Feb 15, 2012I am binding a dataset (dsTest) with a table called "TempResult" to a datagrid (DatagridView1).The purpose of the datagrid is to display test labels (set elsewhere in the software) and to allow the user to enter results into an empty column titled results.To achieve this I've filled the dataset with the required test labels then added a column called "Result" with a default value of 0.00.The user can enter numbers into the "Result" column on the grid then click a button "ADD" to update the changes to the datatset,When I first open the form the datagrid shows the correct information and any changes made to the Result column are updated correctly - all is well.
Private Sub Add_Results()
Dim ResultColumn As DataColumn
Dim Rows As Integer
Dim i As Integer
[code]....
If I close the form and open it up again (i.e. the user wants to add more results) the datagrid shows the results entered the last time the form was use and any changes made to the grid are not updated and the form won't work again until the software is reloaded.
DataGrid Will Not Display The Dataset/recordset?
Jun 18, 2012It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it. The program retreives the records, but does not populate these records onto a datagrid.
Heres my Form code (Form1)
Imports ADS_SQL_TEST_VBNET
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I think the problem lies within the LoadDataBound() Sub routine, but I can't say for sure since I was unable to fix this myself.

Database - DataGrid Will Not Display The Dataset/recordset

Mar 25, 2009I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset.

Using A Dataset To Fill Datagrid In Form - Assign A Color To The Forum "where =open/closed"?
Aug 4, 2009Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?

View 2 RepliesIDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True
Jan 28, 2010I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
