DB/Reporting :: Display Data From 2 Different DataSets In Grid?
Nov 26, 2008
I have an Access table that contains "Customer Number".
I have an ODBC dataset (iSeries IBM Client Access, or AS/400 data) with a customer table in it. I want to link the customer numbers in the access table to the ODBC table so I can show the customer number from the access table and the customer name, city, and state from the ODBC table.
I want to display this information in a grid. I also want to be able to add records to the grid (which adds them to the access table). What is the best way to get started doing this? I am using VB2005. I could use MS Access and have it done in about 2 minutes, but I want to take the plunge and learn VB2005.
But this VB2005 and .net thing seems like they re-wrote the book on programming and I cant seem to get a grasp on it. I have tried several projects like this in hopes of learning, but ended up abandoning them in frustration.

If I wanted to change the value of a column for every row in a datagridview, what is the best way to do it? I have encountered an issue when the datagridview is bound to a filtered DataView and need to know what I am doing wrong. The code I would normally use is
Code: For Each r As DataGridViewRow In DataGridView1.Rows
'don't touch the blank line, it is pointless and will error out
If r.IsNewRow = False Then
'set the current line with the current ID.

Masters of the visual basic arts, I, a lowly noob, would just like to ask for your wisdom (and mercy). For my program needs to determine if the data grid view has any content because if that certain datagridview doesn't contain anything, then I would disable a couple of functions for the program.

I just want to display data in a DataGridView (from SQL - already made the connection) based on what is selected in a ComboBox (data that is also coming from SQL). The 2 are separete on the form. I am using VB 2010.
This doesn't work for me:
objCommand2.CommandText = "SELECT ProductID, Name, Color, Size, ListPrice FROM SalesLT.Product WHERE ProductCategoryID = " & cbCategory.SelectedValue

I need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.
These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.
I also need the ability to clear all events (rows).
I guess the first question is if the data grid view is the best control in VB to use.
Is there a good example on using the data grid on how to add data to the data grid view one row at a time?

I am using a stored procedure to fill a dataset with a large amount of data (47k rows and 8 columns). I am needing to fill two tables with the results of this stored proc.One table will have data representing 47k reps that currently have credit for a transaction. The other table will be a mirror copy of the 1st table with 47k reps that were supposed to get credit for a transaction. This application is going to take credit from one rep. and give the credit to the other rep record in the 2 mirrored datasets. It's taking 30 seconds for the data adapter fill method to return records to my application. I would like to reduce the amount of time it takes for this request to process.
Here's the contents of the stored proc:
Code:
ALTER PROCEDURE [spGetSalesCode]
@Period varchar(15)

how I can better return a relatively large dataset to vb.net more quickly?

need to have a summation field in each row of a grid in visual basic. Each row needs to calculate the remaining quantity of its row and all other rows beneath it. Thus the subtotal field in the 1st row would equal the sum of the shown quantity field for the entire grid.The next row would include its value and all those beneath it. Its subtotal value would be less than the subtotal of the row above it (by the quantity value of the 1st row). My code for the grid is very simple I just can't figure out how to add this iteration.

I am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?
<Grid x:Name="gdHistory" Grid.Column="0" Grid.Row="2" >
<Grid.RowDefinitions>

All I really want to do is a join. Table 1 and Table 2 both have a number that would link the two together. I want to join two fields from Table 2 onto Table 1. I need to have two datasets because there are two different connections being made.I want to push this onto a DataGridView, which only allows a single datasource. So I'm thinking I would need to make a temp table somehow, but since I'm pulling from two different datasets I don't know if that's possible.
