Get A Row Count And Post That Back To The Grid
Oct 1, 2009
Ok, so I have a small program I am building for my boss to keep track of workers at certain job sites. With the way the economy is going my boss wants to track who is showing up at specific sites (jobs) and try to even it out among all the employees - some are not working full time.
Anyway, I have two Access tables linked together with the main table being Employee Data. The second Table is Employee Jobs. Basically I have three forms. The main form on startup will show all of the employees in the company - this is basically a list of all added employees into the database (this is the second form - adding employee info). At a quick glance I would like to have the initial startup form, with grid - show employee info, show the number of jobs each employee has been assigned to. Would this be an SQL statement? How to I get a row count and post that back to the grid so it shows up on startup?

To make this easier I will use a concrete example using movies and genres. A genre can be associated with many movies. Genres can increase over time and so can movies.
The use case is as follows. The user wants to filter movies by selecting his/her desired genres.
So, I have a page where at the top there is a section where the user can pick any combination of genres to filter on using checkboxes. Below that is a list of movies that are in those genres.
In MVC I am trying to implement this using a ViewPage(of IDictionary(of Genre, Boolean)) where the boolean is whether or not a particular Genre has been selected for filtering.
I then go into loop that creates checkboxes for them to select:
<% for each genre As KeyValuePair(Of Genre, Boolean) in Model %>
<%=Html.Hidden("genre[" & i & "].Key", genre.Key.ID)%>
<%=Html.CheckBox("genre[" & i & "].Value", genre.Value)%>
[Code].....
I am aware this can be done using Ajax and I will most likely do it using Ajax but I would still like to know why this doesn't work.

My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]

I have a GridView with a Checkbox on the first column: Code: The thing is that the Checkbox.Checked always returns False. How can I get the checked state of the Checkboxes in this scenario? Or what would be the best approach into updating the aforementioned column? P.S. Note that click on the checkboxes doesn't post back. Nothing happens on the page until the user clicks Save (and that is the intended behavior).

I am developing a small windows application(vb.net) in vs2005.I will have a grid view that will keep on refreshing for every 5 seconds.For that grid, I want to set a background image which I can do.But my problem is, while refreshing the grid image also get refreshed which make the form unpleasant to view. So, I try to make the grid backcolor as transparent so that I can utilize the form background image which will solve my problem. But I got the error message that, we can not set the grid back color to transparent. Is there any way to achieve this.

I am using Vb.Net 2005's stock datagridview.What I am trying to achieve is for the user to drag the mouse across some text within a cell and have it show the number of letters as they are being highlighted.I thought that this would not be too difficult of a task, but once I realized it that it was I started perusing the Internet for quite some time to no avail.

I have an infratistics grid that when I click on a row, the activerow gets set, then I click a button that will open a terminal form and ssh to an IP address in one of the activerow cells. It's not a problem until I connect to another row afterwards and it resets the activerow causing both forms to refer back to the latest activerow which would only be correct for the latest form opened. The problem then is that the terminal form refers back to the activerow cells for various updates. From my main form where the grid is, I open a new frmWodTelnet form to connect to the IP like this: [Code]
I haven't actually tried this yet, can't until next week just trying to get a grasp on how best to proceed. Does this look like it might work out for what I need, to lock the form values back to the original row until the form is closed? Or is there a better option I should be looking at.

when setting a column to identity it will auto increment 1,2,3,4..however if you delete 4 & 5 and then insert another record it will go in as 6.If you do this a lot you end up with huge gaps in the numbers,is there any way to make SQL default back to filling in the gaps and only count higher if there are no gaps?I know I can do it in the application, or even a UDF, I just want to make sure I am not reinventing the wheel?

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"
