C# - Limit Number Of Rows That Can Be Entered In A Datagridview Based On Property Of DGV?
Feb 24, 2010I have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property
Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......
The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.

View 4 RepliesHow To Create Filter That Limit Results (Max Rows)
Mar 27, 2012I have a data bound datagridview on my form. I need the datagridview to sort by oldest date, and then return only the 150 oldest. The goal is to export the 150 rows with the oldest date to a .csv file and then update the date column to the current date for only those 150.
Here is what I have so far:
Dim appPath As String = Path.GetDirectoryName(Application.ExecutablePath)
Dim tdate As Date
tdate = Today.Date
'sort datelastemailed by oldest to be emailed first
DataGridView1.Sort(DateLastEmailedDataGridViewTextBoxColumn,
[Code] ....
I can get it filter by the column "status" and then sort by "datelastemailed". I can also get it to export only those 150 to the .csv file. My issue is that I need only those 150 to have their date column updated to today's date and then saved to the database. The only way I can see to get that done is to set a max number of rows for my databound datagridview and then loop through each row in the date column. How I can create a filter that limits results?

Query Active Directory With OLEDB And Get Over The 1000 Rows Limit?
Mar 5, 2008You can query active directory with an OLEDB provider called ADSDSOOBJECT. This works great except it only returns the first 1000 rows. The following article shows how to work around this limitation in a vb script by setting the "page size" property of the command object. [URL]..I have been able to reproduce that code in VB.NET, but I am having problems getting it translated to OLEDB syntax, because there doesn't seem to be a "Page Size" property, or indeed a "properties" collection of any kind, in OLEDB.

VS 2010 Limit Text Entry In DataGridView?
Jul 21, 2011Okay, 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.

Save Datagridview Rows As New Rows?
Apr 26, 2012It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
DataGridView - Nonvisible Rows Are Still Visible And The DataGridView Is Empty Despite Having A DataSource
Jul 30, 2009I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
