I'm successfully refreshing my DataGridView/Access DB by using the following.[cod]My only problem is after the refreshes the DGV rolls back to the first entry.Is there anyway to have it refresh but stay on the same line?
View 4 RepliesI have a reporting utility for my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link via email (listbox of email addresses) that would let them view the report in Excel or PDF. This is working just fine. Now I just added a button for adding new email addresses and a new windows form with a textbox for entering the email address and a command button for Save Email Address. I am able to save the email address just fine from the small pop-up window for entering the email addresses but after closing the window, the listbox of email addresses on the main form does not get refreshed with the new entry from the textox even though the SQL table EmailAdresses got updated.[code]...
View 5 RepliesI have a datagridview in Visual Studio 2008. I am using the binding navigator to add rows to the grid. I have two text boxes on the form that I am using as the data entry method. I have dragged these onto the form as details items from the dataset and placed them below the datagrid.
I hit add item item on the navigator, fill out the test boxes and then hit the save button on the navigator and it sends the data to the database but is doesn't not update the datagrid. The only way that I can seem to correctly display the new row is to use the Datagrid fill method
My code is below.

I have 3 Combo boxes that have number 1-9 in each, i would like to make it so that if the first one is set to 9 then the and the second it set to 8 then the first 1 is set to 1, i need them to only equal 9 through all the boxes?
View 6 RepliesThis one is causing me a lot of frustration, and as far as I can see, it should work. What I have is a form with 9 ListViews (ListView1 through 9), and I want to add items to them.The issue is, I have a routine that sets which ListView to use. Say I have set it for ListView4, it works initially on the first file, but after one line of code. it reverts back to ListView1 for the remaining files. (itmModelItem = lvwModels.Items.Add(ModelName) in AddModel.

Yesterday s**ked, and today ain't (sic) looking better. I have an application I have been working on and it can be slow to start when my ISP is down because of DNS. My ISP was down for 3 hours yesterday, so I didn't think much about this piece of code I had added, until I found that it is always slow to start. This code is supposed to return your IP address and my reading of the link suggests that should be immediate, but it isn't, at least on my machine.Oh, and yesterday before the internet went down, I upgraded (oymoron) to XP SP3, and have had other problems.So my questions / request:
1. Am I doing this right?
2. If you run this on your machine does it take 39 seconds to return your IP address? [code]
I have another problem:

Bolded line makes an exception: The remote name could not be resolved: 'unkn' I guess it has to do something with threading, and path doesnt generate correctly username, password, and pth are generated from objects in another form, so i did it like this: Dim newfrm As Form1
And then acces the objects that hold user, pass... like: newfrm.textbox1.text
So, why do i get this exception then if im doing it the right way, and how do i get this to work?

Hi
I have a thread that it calling many processes.
While the processes are executed (spends some seconds or minutes in completing all the tasks) I show form "Please wait to complete all tasks".
But one of these processes I have to show a form because the user has to choose a few data. But the problem is that this form is showed minimized.
Already I have tried to show it maximized and to bring it to the front but it does not do it.
how I can show this form to front and maximized?
My actual code is:
f= New frmLPlantillas
f.WindowState = FormWindowState.Maximized
f.BringToFront()
If f.ShowDialog() = DialogResult.OK Then
value1= f.xxxx
value2= f.zzzzz
value3= f.aaaa
value4= f.bbbbbb
Else
Return False
Exit Function
End If
Thanks in advance.
How do I capture the cell value of an entry in a new row in a datagridview? This is what I have so far but it's capturing the previous row's cell value:
Me.DataGridView1.CurrentRow.Cells("License").Value
How can I set a datagridview control to not add a new empty row when I add an entry?
View 2 RepliesIf I wanted a character in a datagridviewcolumn replaced when it's typed, not when the cell is left, how could I achieve that? Is there an eventhandler tied to that?
View 1 RepliesOkay, I've got a datagridview in my WinForms app that auto-builds the column list from a datatable schema. It's working fine, except that it allows the user to enter values too long for the database field. For example, I have a "name" field that is defined in the Sql-Server database as a varchar(50). Is there any way to limit that cell (column?) so that it only accepts 50 characters? Right now it lets them enter anything and throws an exception later.

I created two tables(FIRSTtable and SECONDtable) in the mysql database and two tables that are related.[code]...
Relations between the two tables using the product_id column with UpdateCascade and DeleteCascade. Both relationships are functioning normally when I try with the sql script. Suppose I delete all product_id in the FIRST table, all existing data in the SECOND table will be deleted.
Both of these tables displayed in datagridview. When I delete all the data in the FIRST table, the all rows in datagridview FIRST table will be deleted, also the data in mysql the FIRST table will be deleted.
I try to open the mysql database, the data are in SECOND Table also deleted, the problem why the view that in the second datagridview, can not be deleted, still keep the previous data? How to refresh datagridview binding in vb.net or C#? [code]...

View 5 RepliesI have a vb.net form with a dataGridView
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)

I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
The membres table is an access table
I'm running the app in visual 2010 debug mode.
I have a problem with a datagridview control, when first loaded with existing data it shows the correct rowcount figure.However, I have a function that when invoked triggers an oledbcommand to clear those records from the database (access) and load new ones from a file (excel/text).The oledbcomands work fine, and the gridview refreshes with the new data fine. However, the rowcount after this refresh is always 0, even with records. What I am doing is creating a module for my app that allows the user to specify the column title and types for a file import - and the procedure will read the header row from a txt/csv or excel file automatically.[code]If I just make edits in the datagridview (as in not invoke the above) the rowcount returns properly.If I close and re-open the form the new data appears, and the rowcount property returns fine also, but I don't really want to have to tell the user to close and re-open it before making any changes.I must be missing something on the refresh or with the datatable or adapter side of things.
View 2 RepliesIn a windows form I do have a datagridview. When a user pushes the button, the underlying datasource of the datagridview (a dataview) changes and the new content with new columns is shown. This works fine, only problem is that the header-height differs and that the datagridview does not properly display the smaller headers until I click into the first datarow of the datagridview. Simply using the .refresh()-method of the datagridview after assigning the new datasource does not seem to work.
Here is a little code-snippet showing how I assign a new datasource to the datagridview.
Dim view As DataView = myDataTable.DefaultView
With Me.MyDataGridView
.Columns.Clear()
.AutoSize = True
.DataSource = view
For Each col As DataGridViewColumn In Me.MyDataGridView.Columns
col.ReadOnly = True
Next ...
I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.
