I have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

View 1 RepliesI have a table in my MySQL database and it contains these items:
User_ID(Primary key, auto-increment)
Username
AvatarPicLink
Location
How can I insert everything into a Datarepeater? Username would be in a Label as would Location, and AvatarPicLink would be in a Picturebox.
Here is what I have but it only works when clicking on the row. I have tried a For Each and it still only does it when clicking on the row and not every time.Basically, I am trying to get a button to change the way it looks or if it even appears and them making a picture box appear or not.

I am using the Datarepeater control to make a report. I am including the a couple of bound labels and a checkbox in the Datarepeater item template. When I run the report and multiple items come up, I'd like to use the checkbox and clear the items by resetting there values to NOTHING. When I check the checkbox for the item, how do I code it so row.text=nothing only applies to the row that the checkbox is on?
View 1 RepliesHow do i make sure that the changes "done" by a user interacting with a DataRepeater control are reflected in the corresponding database source table? I have used DataRepeater in VirtualMode, do I have to supply my own code that will "actually" make corresponding changes to the actual tables, or is there a way of "configuring" or "binding" the controls on the DataRepeater to the "dataSet" so that the changes made by the user are reflected automatically in the underlying table? Whatever I have tried so far has yielded no results; whenever i edit the data on the control, the actual data is not updated. I attach a file showing the only events under which i have put some code: Load event of the Windows form, and the ItemValueNeeded event of the Repeater Control.
View 4 RepliesI am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.
View 8 RepliesMy assignment is to create an application that allows the user to type an item's price into a single textbox, add the price to the previously entered prices, and display the total charge which includes a $15 shipping charge and a 3% sales tax.Example: I type 10 in the textbox and click calculate. the subtotal (before tax and shipping) reads $10. Next, I type 20 in the textbox and click calculate. The subtotal should now read $30.I have everything working fine except adding the different prices. I cannot figure out how to retain the value of the subtotal and add it to the next value entered.

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

I need to allow labels in disabled panels to retain a their prominent forecolor. So, I am considering replacing all labels in panels that become disabled with LinkLabels. By disabling the control and setting its disabled color to black it holds the color. However, I have always been of the opinion that one should use the lightest control possible.

We have an ASP.NET application that queues some of its long-running operations (generating reports, for example) into the ThreadPool using System.Threading.ThreadPool.QueueUserWorkItem.
We run the ASP.Net application pool using a specific domain service account so that it can access remote resources, including files and databases. When the execution starts in the ThreadPool, the user identity of the thread is set to Network Service, which doesn't allow us to access the remote resources.The web application can be accessed by users in different countries simultaneously and the format of the data that we provide to each user is based on their culture settings (using the standard globalization settings in web.config). When the queued thread is started, it has also lost this information and reverts to the default culture for the operating system.
Now, we can probably get around most of these issues by capturing the current user identity and culture in a state object and passing that to the background worker, then impersonate the user and set the culture on the thread, but this seems like a very "unclean" way to resolve this issue.[code]...
I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.
View 1 RepliesI have a DataGridView, bound to a dataset. All the columns are sortable (.ColumnSortMode.Automatic). The user may change data in certain columns, although not the first ("key") column. When data gets changed on a row, I change the backcolor for that row (to show it as dirty). At some point, the user will do something with all of these changes.
My problem is that I still want the user to be able to resort the data by any of those columns. When it's sorted, though, I lose the backcolors that I changed. I do know which rows are dirty, this is just a cosmetic issue. Isn't there a way to retain those backcolors, or any other such row attribute?

Is it possible to get value of a text box, say at row 4 of a datarepeater. I did it by moving control to it, but that does not work the way I want. I used code DataRepeater1.currentIndex=5, and then picked the value. Is there any possibility of getting the value without moving control to this row. I mean the way we get value from datagridview (vrName=datagridview1.item(1,1).value)
