Datagrid Search But Get False Selected Rows. Contains Code?

I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
We are using a bound datagrid to pull information from a database. how do we send a selected row from that datagrid to another datagrid in a different database.

This is my current code, it searches for anything entered into the textbox against the row "surname", but I also have a first name row and a Order ID row. Instead of searching against one row, i want to to search all the rows, and fill the datagrid with anything it matches it with.
Here is a sample piece of my code, the problem that I am have is that I can only selected one record at a time to mail merge, regardless if I select 5 rows from the datagrid. Or I can mail merge the entire datagrid, but I want my users to be able to select the data that they want, whethere it is 1 or 5 rows and be able to mail merge based off the selection. I've been pulling my hair out over this, I know it is something simple that I am missing....Please help...I am working in VB.NET visual studio 2008

View 1 RepliesI have a CheckBoxList on my page that isn't behaving very well.The idea is that once the submit button on the form is clicked, the app should clear the database table of all rows pertaining to the specific user and then re-insert new ones based on the user's CheckBoxList selections.The problem is that regardless of whether or not any (or all) items in the CheckBoxList are selected, the app keeps getting Selected = False.[code]I'm aware of the potential for SQL Injection here. I'll be going over to using Parameters as soon as I have the loop working.

I'm writing a little program for class that determines what your Chinese Animal Sign is based on the birth year you input. My test expression for the structure is a boolean. If it is true, the case is entered.
The value entered must be at >= 1924. If not, the first case should display an error message. If it IS >= 1924, it passes to the next case to see if you were born under the first animal sign and so on.
I set a breakpoint to find out why it was displaying the error even though I input 1924. The boolean for "< 1924 = True" comes up false, so that case should be skipped, I thought. But the code enters that case anyway and displays the error.I'm new to case structure, but I understand if statements very well. What am I missing?

View 1 RepliesOur site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:
Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.
I saw another guide which told me to do:
For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something
Next
But that gives me the error:
Overload resolution failed because no accessible 'Item' accepts this number of arguments.

numbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..
My code:

View 14 RepliesI have a form called LogIn.vb which has no errors. After log-in, it opens the MainForm.vb which IsMDIContainer property is set to true. From the MainMenu, it opens a child form called Assure_Benefits.vb So far no problem up to this point. When Assure_Benefits.vb loads, it displays 2 DataGridViews with datasourses from my 2 tables in my database.
There is still no problem with the loading. Now, to show the difference between different user types, I only allow the admin to edit the DataGrid. SO I set the readonly property to true when UserType = "user".
I have no problem doing that. My problem is I want to add some codes besides the readonly being set to true and false but other codes are not executed and the program does not display any errors at all. i tried to add messageboxes on the if and else conditions to try if added codes will work but even the messagebox does not appear though the codes next to it are properly executed.
When my Assure_Benefits.vb loads I call for the subroutine below.
Private Sub SetControlProperties()
If LogIn.UserType = "admin" Then
MessageBox.Show("Yes") 'This line is not executed
[CODE]...
I can't seem to understand why the first code is not executed when the next codes works fine.
