I'm working in VS 2008, vb.net. I have a data grid that is getting filled based on a store procedure. When I preview the datagrid, I will get 29 rows back. This includes rows that have NULL values in it. And that's what I need. But when I run the program, it will only return in the Datagrid 12 rows, the rows that don'r have any NULL values. Where or how can I change it so the DataGrid will show NULL values?
View 2 RepliesI am using Visual Basic 2008, and SQL Server 2005. I have a single-user client-server app (i know that sounds stupid, but its for future expandibility and also the fact that documentation was easier to find for SQL server than Access files).The app is basically a medicals records system.
In one of the tables, called 'visits', it stores the dates on which each patient visits the doctor, among other things like symptoms and diagnosis. Another table stores all the patient names and IDs along with other details, and a relation has been set up between the patient ID in the patients table and the visits table. So i dragged the visits table from within the patients table (to get only the visits for that particular patient), and dragged it onto the form to make a datagridview. However, the datagridview didn't seem to recognise MS SQL server's smalldatetime format, and tried representing it as a picture. When i changed the format of the column to text boxes, it gave me a type mismatch error (Inconvertible type mismatch between SourceColumn 'VisitDate' of DateTime and the DataColumn 'VisitDate' of Byte[].) That means, for some reason, it is trying to convert the smalldatetime data to byte before it shows it, which is leading to the error. How do i fix this?
Also, I remember seeing some option for using completely custom column types in the datagridview, but i cant seem to find it now. The options in 'Edit Columns' are very limited, but i would like to set it to a masked text box, or something with a fixed format. Can someone recommend a good column type for representing dates, and how to make the datagridview show that kinda column?

View 12 Repliesi was wondering if there are other ways of showing data coming from the database.currently [ as per in my previous thread] i am using a [bind] datagridview.e.gthe table has
id, name, quantity
im thinking that listbox could be one, but it just shows 1 [e.g name].
I have a database and I was thinking about using either a List Box or Data Grid to show the data. Is there is another way of showing the data? Also, when the user 'double-clicks' on the data in the List Box or Data Grid then I would like the information to come up in a new form. I know how to show a new form but I don't know how to get the information from the one that has been clicked.

I have a datagridview control that will be used to allow the user to input records. The control uses a combobox column to select a type of service. There is a rate associated with the type of service that I then want to display in the grid. The user then enters a quantity and the last column mulitplies the rate and quantity to get a total. I have the combobox , quantity and total columns figured out but I don't know how to get the rate column to automatically be selected when the type of service is selected. Below is the code.... sets up the datagridview

View 6 RepliesWhen you create an XML comment in C# and collapse it you only see:

But in VB you could potentially see

Having that line over your code can introduce lots of unwanted noise when trying to debug a class. Is there any way to turn off xml comment previews for VB?

View 1 RepliesI am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.

It says that update is not a member of the tableadapter... Why is that?
On the left half of my screen I have a datagridview. On the right half I have a document preview pane.As I change rows on the left half, I use the CurrentCellChanged event to open the document associated to that row in the previewer.This works fine, however, the focus is then placed in the preview pane which prevents the user from being able to use the arrow keys to step down a row at a time.To combat this, I made the final event in my CurrentCellChanged routine set the focus back to my datagridview. Unfortunately, even this doesn't always work because of what seems to be a timing issue.If the document to be previewed takes more than a fraction of a second to open, the code to move the focus to the datagridview is executed but after the image completes drawing, the focus is moved back to my previewer.I don't want to use a timer to force a delay and a DoEvents causes me some other issues.Is there some other event I can use to determine when my preview pane is complete and then and only then set the focus back to my datagrid?
