I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database. User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?
I have the following code in which it supposed to remove rows that have the first column checkboxes checked, but it only removes one row at a time.If you have more than one checkbox checked, you have to click the command button each time to remove the row.It seems that the logic is correct to remove multiple rows if more than one checkbox is checked, but it doesn't work.

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
Private Sub btnMailMerge_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMailMerge.Click Dim objWordDoc As Microsoft.Office.Interop.Word.Document 'Dim objWordDoc As New Microsoft.Office.Interop.Word.Application
I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.
how to do cursor moving from one grid it effect to another grid.example Grid A and Grid B have the same number of rows. when I click current row on data grid A, the selected row on data Grid B also follow data grid A..
I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.
I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.
I have a DataGridview1 box and a listbox called rebuilt which contains the raw data I need put into an array and then dumped into the DataGrid.[code]....
Our 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.
For Each row As DataRow In dgrFarms.Rows Dim sendtroopid As Integer sendtroopid = row("idColumn") 'Do Something Next
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: 'when adding a new row Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click

My problem is with the for loop when deleting a row.

i want to make a datagrid with 2 columns and many rows
the columns i want to have databinding with a datatable i want the 1 row 1 column of datagrid have data from 1 row of datatable i want the 1 row 2 column of datagrid have data from 2 row of datatable
I bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.
I want to ask about how to disable the button when the datagrid have 9 rows? i want to control the button.after the datagrid have 9 rows, then the button.enabled=false.
i need bit of support in my vb coding. i've publish data onto a datagrid(in vb express 2010). i just want to highlight entire row once the search data is found(in lime color) and color should be remain in that particular row when searching next records. so that user would easily know which records are searched and which are not by looking @ the color.
In my datagrid, I know the number of rows that it will have - it will always have 12 rows.Can I scroll through the cells downwards via the columns instead of the usual horizontal way via the rows?
