Asp.net - Cannot Add DataTable Values To GridView
Jan 10, 2012Here is my code
Dim dt As DataTable = New DataTable("Intervenant")
For Each column As DataControlField In grdvIntervenants.Columns
dt.Columns.Add(New DataColumn(column.HeaderText))
Next
[code]....
I am developing in ASP.NET using VB.NET as background code. I am on vs2008 with windows 7 enterprise edition.I have just restarted doing VB.Net and my first time using a gridview without a DataBase, so maybe I am missing something. Basically, I am trying to add a DataRow (dr) to a DataTable (dt) and then put said DataTable into a Gridview (grdvIntervenants).My first step is to take the gridview and put all its data into a DataTable. Then i create a DataRow(dr) that I populate with variables and I add said DataRow to the DataTable. After that, I put the DataTable as the DataSource and bind the GridView.
The problem is that my GridView shows the rows but they are empty.While debugging, I found out that this error was beside all the DataRow.Item:"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user" Seraching for it on the net.I did not totally understand the error, so i tried many different ways of adding the data into the DataRow but to no avail. I also tried different way of adding the column thinking the index problem might be coming from there, but again, the problem persisted. Now, something I found weird was that the Item property of my DataRow gives the quoted error, but I see the values into the ItemArray of the DataRow.I also found out that the same error appears beside the columns property into the dataTable.When I try to access the data from the DataSource in my rowDatabound method using the DataBinder, it gives me null results...

ASP Gridview: Adding Two Values And Validate?
May 26, 2012I use GridView to show/edit data in the database. In the GridView there are two columns called mark1 and mark2. What I want to do is when user clicks update, the program should check if the values entered at mark1 and mark2 sum to 100. If they don't the program should cancel the update and show an error message. How do I do it? I use ASP.NET with VB.

View 2 RepliesComparing/validating Gridview Values Among Each Other
Jul 8, 2009I have a gridview(editable).
It may have more than 1 row with columns startdate and enddate.
StartDate EndDate
4/4/09 6/6/09 (valid-existing row)
1/2/09 3/3/09 (valid-existing row)
7/7/09 9/9/09 (valid- edited row)
3/3/09 6/6/09 (Invalid - edited row )
When you see the above table/gridview, you will know what I want to validate.
I should be checking whether there is any row having start-end dates lying within the existing date range, if so I should invalidate them.
I shd have only distinct date range in my rows.
How do I do that.
May be Useful note: I will be able to check which column name I tried editing in that row.
Do any of you have some ideas how to create a logic to accomodate my validation issue in my webbased gridview control ?

View 2 RepliesDB/Reporting :: SQL Select Query In Form - Form With A Datagridview That Displays All Of The Values
Mar 26, 2008I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L
[CODE]...
Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!

Getting Parent Form's Property Values In A Child Form
Feb 20, 2012I have a custom form that I use instead of msgbox for a number of reasons. The initial reason was to keep the message centered on it's parent rather than the screen. There are many articles about this but I still have not found an elegant way to get access to the Parent's properties from inside the Child without passing them in (by one way or another).
In the child form the me.parent, me.parentform are not instantiated and apparently can not be used.
The point is to have this form be totally encapsulated with the logic being self contained. This is not an MDI child, and I do not want it to be due to the limitations on MDI children.
My current workaround looks like this I use a ShowMsg Function in my MyMsgBox form which looks like this:
