I have a datagrid and has items of quantity, product, desc etc is it possible that i will get all the items in my datagrid and put it all in my database im thinking of using the datatable or dataset.
View 35 RepliesI have
- system.windows.forms.timer with a 20 second interval
- it checks the status of a website using HttpWebResponse
- I have a datagridview with a column that holds the website(s) name
- Once the timer gets the results its places the results in another column on the datagridview
- a for loop will loop through the column that holds the websites name and posts the results for each row/website.
If all the sites are up and running it works fine. If a site is down HttpWebResponse takes about 10 seconds to return the reason why and the program can not be used during that time. So I read up on timers and realized there were 3 kind. The System.Timers.Timer sounded like a better solution since it runs on a worker thread. This sounds perfect since the user can still use the GUI without waiting for the timer to realize the site is down.The problem I have is if i tried to get the row count of the datagridview so I can loop through the sites messagebox. show (frmMain. dgvMonitoredSites.Rows.Count - 1) it will always return 0 even if there are over 10 rows. It's almost as if it's looking at a datagridview in another instance. Is there anyway I can get this system.timer to see the items in the datagrid?
I have an application that saves details to then be viewed in a datagridview on another form. Clicking on an entry in the datagrid (I want to make this double-click, but haven't bothered to try yet) highlights the row, and loads the values to a new form, in read-only text boxes. Clicking Edit changes the read-only value of these text boxes and allows you to edit (obviously) the contents. I have another button, Save which I want to click to commit the changes to the loaded items in the datagrid.

Me.BindingSource.EndEdit()

It says that update is not a member of the tableadapter... Why is that?

I want to populate a listview with items from datagrid view. I've been searching for solutions but it seems that all the scenarios I found were about populating listview with items from tables in database, not from another listview or datagrid view.
I'm trying this code:
For count As Integer = 0 To (DataGridView1.Rows.Count() - 1)
Dim row As DataRow = DataGridView1.Rows(count)
Dim item As ListViewItem = New ListViewItem(row(fieldfirstcol).ToString())
item.SubItems.Add(row(fieldsecondcol.ToString()))
ListView1.Items.Add(item)
But it doesn't work; it says DataGridViewRow cannot be converted to DataRow.
I want to loop through all the items in the datagrid and compare them with a particular item(unique) present in the datagrid itself, and if it is not equal that unique item ("My Pipeline" is the name of that particular item) with which i want to compare rest of the items with then delete that item and move on to the next item and compare again.

Using Visual Basics Express 2008, I am trying to add items to a combo box FROM column headers in a datagrid in a separate form. I have written the code to create the datagrid from an external file but can not get the headers of that datagrid to populate the combo box in a separate form.

Dim dt As New DataTable

While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.
View 1 RepliesFriends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CallLogDataSet.CallLog' table. You can move, or remove it, as needed.

I have spent the last day reading countless threads and webpages about updating a database with data entered into a datagrid.I have a datagrid with that I populate from an access database and the datagrid has 4 columns, 'Item Code','Description','Quantity' and 'Unit'.Another 3 columns ID, Division and Bid Refrence number are hidden. My aim was to use these as a unique reference so that I could update the changes made.I can show the datagrid just fine, no problems at all.

View 6 RepliesI am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty. I managed to track this back to the text not being passed from my datagrids footer to the sql parameters. I tried using a string first and then passing that to the parameters but they were also empty. I am accessing the control using the following line.
sqlcmd.Parameters.Add("@GoodsDesc", SqlDbType.VarChar).Value = CType(e.Item.FindControl("txtGoodsDesc"), TextBox).Text
The control itself is defined using
<asp:TemplateColumn HeaderText="Goods Descriptions">
<ItemTemplate>
<asp:Label runat="server" ID="lblGoodsDesc" Text='<%# Eval("GoodsDesc")
[Code]....
It's like the text in the footer isnt being tied to the control before I call it.

View 8 RepliesVisual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.

I'm having a database, using GridView I retrieve the data into my WEB application.Then I set the rows to editable (not sure if it is fully completed) and when I edit some cells I want to update the GridView AND the database behind.When I click on 'edit' then the button is changed to update. I get some unhandled exception. I don't expect anything else since I didn't put any code in the update methods like RowCommand, RowUpdating, RowUpdated, RowDataBound.
