DB/Reporting :: Cant Set Current Cell On Form Load
Jul 17, 2009
I am using this code at the last line of my form load. I want the position 5,5 to have the cursor set at it. It works when then datagrid is already open:[code]However, when I use it on the form load, you can see that it was selected on the datagrid, but the cursor is set at textbox1...which happens to have the first tab order on the form, even though I have acceptstabs off. Can anyone tell me why this would happen? Basically, it is setting the cursor at the cell I want, but after the form loads, it jumps to textbox1 and highlights the text.

I have a form with multiple datagridviews. On save the entire dataset will be serialized to a strongly typed property bound to a sql varbinary(max) Works fine. Of course the current "dirty" cell will not be saved as mentioned here :

My problem is the user could be coming from any one of 20 datagridviews when they click SAVE. Is there any way, short of checking for a dirty cell in each datagridview to commit any dirty cell before the save ( clicking another textbox control before the save does the trick but calling the focus() of that textbox prior to the save does not ) I was thinking perhaps catching the event of leaving the grid but it seems the base problem is clicking a button (for reasons I think I understand) does not fire lostfocus events for the current control and it doesn't seem the click handler args knows what the last current selected control is.

I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

completely understand what it does, when the cell value is changed the color of the cell changes according to the value selected.
Now, how would i change this code so that it works when the form loads? so cells show the color when the form loads. red for unpaid and green for paid.

how can I put the blinking cursor inside a specific cell on form load? I want the effect to be kind of like when you have a form with text boxes and when you set the tab order correctly, the first textbox will automatically have the focus and you can start typing right away. On a related question: how can I make the enter key activate the form's accept button when you're inside a cell?

So I've got 2 unbound datagridviews, and am providing a push/pull interface where the user can move records from one to the other.
Grid A is read-only and the selectionmode is set to FullRowSelect. Grid B has a read-only DataGridViewTextBoxCell, an editable DataGridViewComboBoxCell, and an editable DataGridViewComboBoxCell.
Because the grids have different columns, but represent the same records, my notion was to create the datagridviews with the same column structure but hiding certain columns, and then just move the DataGridViewRows back and forth between the two, which seams to work.
The problem is that if I go into column 2 or 3 in grid B, I get "Current cell cannot be set to an invisible cell".
I can select cells in column A and I'm fine. It should be noted that on grid B the hidden columns are 4-7.
I know there's a problem when the CurrentCell attribute is set to a hidden cell, but I'm clicking visible cells. I inserted a breakpoint on the CellClick event of the DGV, and again for column 1 that works fine, but on columns 2 and 3 it looks like the error is occuring before the event even gets fired.
Is something in the background setting CurrentCell to one of the hidden cells before firing the event?

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)

In my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?

I am working on an app with the datetimepicker. I have everything working but wanted to go one step further and have the current date show when the app is opened up. Is this possible? Or does it always default to the date in the properties? When I reset the form I can get the current date to show.

Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.

I have written a class to model an object in vb.net, using vs2008 and framework 2.0. I am serializing the class to an XML file for persistent storage. I do this with a method in the class like this:
Public Sub SaveAs(ByVal filename As String)
Dim writer As New Xml.Serialization.XmlSerializer(GetType(MyNamespace.MyClass))
Dim file As New System.IO.StreamWriter(filename)
[code]....
I now want to do a similar thing but reading the class from file to the current instance, like this:
Public Sub New(ByVal filename As String)
Dim reader = New Xml.Serialization.XmlSerializer(GetType(MyNamespace.MyClass))
Dim file = New System.IO.StreamReader(FullPath)
[code]....
However, I cannot assign anything to "Me". I've tried creating a temporary object to hold the file contents then copying each property and field over to the current instance.I iterated over the properties (using Reflection), but this soon gets messy, dealing with ReadOnly collection properties, for example. If I just copy each property manually I will have to remember to modify the procedure whenever I add a property in the future, so that sounds like a recipe for disaster.
I know that I could just use a separate function outside the class but many built-in .NET classes can instantiate themselves from file e.g. Dim bmp As New Bitmap(filename As String) and this seems very intuitive to me. how to load a class into the current instance in the Sub New procedure?

I have a database app where on a button click, I export the current record to crystal report which in turns converts it to a PDF file. Upon application startup, I export one record into PDF just fine but when I move ahead to the next record and I click the export button, the new PDF file that was exported is now blank. If I restart the app, I can then export the one record again but any subsequent record will export to PDF as a blank PDF file.
To sum up:I can export one record once using the below code snippet but when I try it for a second time on another record, I get a blank PDF file (only the crystal report formatting is in the PDF).
