Refreshing DataGridView After New Info Recoded Into SQL DB

Mar 28, 2011

I have a Data Grid View that is attached to a binding source. The binding source is pulling from an SQL database. The form I'm creating has a bunch of text boxes and then a record button which records the information back into the sql database. After the record button is pushed I want to have the datagridview pull the data again from the SQL database to pickup the new information. The BS has another BS for its data source, the other BS has another BS for its data source. That final BS has the DataSet for its data source....

BS3 --> BS2 --> BS1 --> DataSet...?
The .refresh for the datagridview does not pull in the information. I do have a filter applied to the binding source that the data gridview is pulling from.

Refreshing A DataGridView?

Jul 26, 2010

I have a form that uses a tab control. On the main tab is a DataGridView containing Customer information. If I double-click on a row in that DGV, I go to another tab in which I can either make changes or delete the record. Whatever I do, whether it be delete it or modify it, after clicking on the appropriate command button, focus goes back to the main tab. What I wish to do is have the changes be reflected on that DGV. If the record is deleted then I want the DGV to not have that record present. This DGV is bound to a BindingSource. What control/dataset to I need to "Refresh" in order for this to happen?

Sep 11, 2010

I have a datagridview control on my form which i have populated it with values from a dataset. Now i am using a button to delete these values from the database which is working perfectly for me but the problem now is anytime i delete the old value still shows in the datagrid which shouldn't be so so i wrote the code to refresh the grid after deleting but is still not working for me as i want.

Me.UserAccountsDataGridView1.Refresh()

But onething is the value i deleted doesn't show when the form reloads again. but at run time it still has the old value in it again.

Refreshing Datagridview From A Second Form?

Jan 24, 2011

I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.

My data is loaded into the datagridview as so;

Public
Sub ShowVoucherLines()
cmd =

IndexOutOfRange From Datagridview When Refreshing Dataset?

Oct 6, 2010

I have a datagridview on a form that is bound to a table in a dataset from another class.I use a data adapter to .Fill a table in that dataset and the grid displays the data fine.Works fine.On my form I have a textbox the user can type in that will will pass a parameter to the storedprocedure used to fill this table. So on startup the textbox will have "%" in it. and then the user can type in "F%" and get everything that starts with an "F"

So when that textbox changes I launch an async refresh (.BeginInvoke) to do my refresh. The table gets populated with the reduced number of records (I check ds.table(0).rows.count and it is correct)

But the datagridview then starts throwing datagridview.dataerror events. "System.IndexOutofRangeException : Index # does not have a value".It looks like the dataset is getting filled correctly and not having any issues, but the datagrid is not liking this update. The index out of range error is so common that I'm not finding what I need through searches.

Refreshing DataGridView After Editing A Record?

Mar 12, 2011

I have a DataGridView bound to a datatable which comes from an SQL Server database.When the user edits a record my update statement changes the field datetimemodified to reflect the last date and time the record was edited (as stored procedure). The new value for datetimemodified is not brought into my DataGridView.

1) How do I refresh a DataGridView bound to a DataTable? Is there any way to refresh or resync only records that have changed instead of the entire DataTable? (Note: my update statement is working fine. I'm only wondering about refreshing the DataGridView.)

2) Would it be better to change the value of DateTimeModified on the client side so that I can avoid a refresh (assuming that this is the only reason I need to refresh the data)?

VS 2010 Prevent Datagridview From Refreshing?

Mar 5, 2011

the Datagridview is included in first tabpage. first tabpage is the search form and the second tabpage is the record detail view. user is switching and working between those two continuously.

The problem is that everytime user selects the tabpage1 the datagridview repaints itself. there is about 6000 rows in datagridview so it takes about 2-3 sec to paint itself. I know the delay is normal and can't avoid that. but it affects the tabpage selection. tabpage1 isn't selected completely until the Datagridview1 finishes it job. in this time the tabpage1 and tabpage2 gets combined and confused.

is there a way to put datagridview processing in backgroundworker or something that doesn't affect main UI ?

"Refreshing" DataGridView Data Between Forms?

Nov 10, 2011

I have a DataGridView on FormA and a DataGridView on FormB. The DataGridView on FormA is initially populated from a file. This same file is being reused when data is saved from either form.

What works: I show FormB by clicking a button (control) located on FormA and all of the data that is in FormA's DataGridView is read into the one on FormB from the file. I can make changes to the DataGridView on FormB and save back to the file but when I close FormB, the data on FormA remains the same as originally read in.

What is needed: If I make changes on FormB, what is the best way to refresh the DataGridView on FormA when I return to it? FormB is closed at this point. I tried to include a call (as the last statement) in the button control on FormA to read the data from the file again as this works initially but nothing happens.

Note: the FormA's DataGridView is also in a Tab control if this makes any difference to try and get it to refresh.

Active Directory Info Into DataGridView

Oct 20, 2011

I am trying to get information from AD and populate it into a DataGridView. The code is as follows:
dirEntry.Path = "LDAP://PATH"
Dim dirSearcher As DirectorySearcher = New DirectorySearcher(dirEntry)
dirSearcher.PropertiesToLoad.Add("cn")
dirSearcher.PropertiesToLoad.Add("DN")
dirSearcher.PropertiesToLoad.Add("description")
dirSearcher.PropertiesToLoad.Add("info")
[Code] .....

The DataGridView has columns defined for all the items like "cn", "DN", "description", "info" etc. From the above code, I can only see the "cn" getting listed. I did try to add using the following lines in the "For" loop but cannot access anything.

DataGridView1.Rows.Add(dirSearchResults.GetDirectoryEntry.Properties("DN")(1)) 'Add DN into the second column
DataGridView1.Rows.Add(dirSearchResults.GetDirectoryEntry.Properties("description")(2)) 'Add description into the third column

How do I access the other fields from the AD record and how do I populate that information into the DataGridView?

DB/Reporting :: How To Save / Load Info In DataGridView

Nov 30, 2009

I'm working on a simple "sports management" game just to test out whether I could make an actual one some time in the future, but for the life of me I haven't been able to figure out how to save the contents of the datagridview. I want it to be saved in a format that doesn't require the user to have Access or any other program, so that the only thing users need are the .exe and the database file. Another question about the datagridview: How do I access the content on specific rows and columns of the datagridview? If I want TextBox1.Text to be whatever is written on Row 4, Column 2, how do I access that information?
