Repositioning Datagridview Record Pointer?
Apr 27, 2011
I have a form that contains a datagridview, which is working properly. I want the user to locate specific records that are displayed in the grid. To that end, I have a sub that uses the datatable select method to find rows within the defined record set:
Dim
strFind
As
String[code]......
As far as I know this is working, as no exception is thrown.Is it possible to have the grid display this record if it is found without having to rebuild the grid?

How can I remove the first column in a datagridview. I mean the first column with the record pointer? I am using VB.NET 2005. Also I am not binding the control to any database.

I normally hate posting to these forums - but I've reached my wits end. Before posting I've searched all over the internet and no one seems to have come up with the solution.
I have a flowlayoutpanel with a number of buttons in it - I simply want to be able to click and drag a button and reorder it. Sounds simple but its driving me mad! I've spent hours searching the net for an answer but with no luck - the closest I got was a guy showing how its done in C#....No clue how to translate it.

I have a Main form that has a split container in it. In Panel1 there is a treeview control. Panel2 is initally blank when Main loads. Upon clicking on one of the nodes in the treeview a form will load in panel2 and adjust the location of the controls based on the size of panel2. The controls are all in a panel themselves so that I am only moving a single object.
Moving the controls when the form in panel2 initially loads works great. But if the size of the Main for changes then the only way to get the controls to reposition is to click on the treeview and reload the form in panel 2.Code for the tree.
Code:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Me.SplitContainer1.Panel2.Controls.Clear()
[code]....
I tried to with code in the panel2_resize bit i got an error as soon as I clicked on the treeview as i did not know which form was currently loaded. What would be a method to accomplish repositioning the controls in panel2 regardless of which form is loaded?

How can I declare pointer to pointer in ATL. Actually I have a handle which I want to pass by address to function. As shown below
STDMETHODIMP Function(HANDLE* hHC) //HANDLE declared as void * so actual type is void **
OR
STDMETHODIMP Function(LONG **hHC)
And want to access this function from the VB client.

I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.

I have a DataGridView.datasource bound to LinkToSql. I fill the data based on a sequence number. If the sequence number is not part of the the data, I will need to add a record. This should be easy and make sence, but it would appear, at least to me to be a bit more difficult.The grid will not add a new record if the LinqToSql query is empty

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)?

I would like to save records in my unbound datagridview to a table in my database. The datagridview was manually created during design and is not bounded to any table. After the user has filled in the rows and columns, I would like all the rows to be inserted into the table. How do I go about this?

Visual basic 2010. I am having a problem with updating on a DataGridView that has me confused.
I have a DataGridView on the first tab page that is displaying data in a DataTable.
On the second tab I am updating the current record on the DataGridView.
The text fields on the second tab are bound to the DataTable in the following manner
rnameTxt.DataBindings.Add(New Binding("Text", TableData, "rname", True))
When I move to the second tab the correct data appears in the text fields.
When I modify a field on the second tab the modified data appears in the DataGridView, on the first tab page. But when I check for changes in the DataTable in the following manner
Dim ModifiedRows As DataTable = TableData.GetChanges() I do not see the modified row - i.e. ModifiedRows = Nothing? Why is the modification not being identified???
