I'm trying to change the values of some of the controls in the ASPxGridview Edit Form, however they are not changing. It seems to be resetting? How can I do this and in which event would I do this in?

View 2 RepliesInside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.

I am a student and totally new to vb.net
I'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:
View 7 RepliesVBExpress 2010 .Net 4.0 I'm trying to have a form that you click on a button and it goes to a new page of the same size in the same location. An example of this type of thing would be the different pages of an install wizard. In this particular project, I have an "instructions" page that you click on that takes you to a new form. On this page is a "back" button that takes you back to the main screen. I'm just not sure how this type of thing is normally done. What I have done works, but you can see the page 'flip' a little, and the form button on the taskbar disappears and reappears as the new one loads.
[Code]...
and I have an equivalent subroutine on the other form to get back. At first I had the Three middle line of code interchanged, which looked much smoother, but for some reason it didn't work on the first click, upon which the form would suddenly move to the wrong location, after which it would work fine, no matter where I moved the form.
I have a feeling that this is probably done in a completely different way, but can't think of a better way of doing it. One way would be to just use one form and change the controls instead, but it would get quite cluttered.
I am using VB2008 Express. After making changes to the position of controls on the form, the controls position reverts to the original position when the program is rebuilt and run. At first, there is no problem, but after 30 minutes working with the program, the problem begins. I am careful to keep all the files together. I am using XP Professional and .net 3.5

I have designed a form in VB.NET. At design time I have placed two buttons on it. When I run it, the form size looks smaller and the buttons I have placed at the bottom are not visible. Also the alignment of the text and picture box is also different from what I set at design time. Computer at which I am running the form is using a different resolution.

i am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]

I am loading a listbox with lines from a txt file. Now I would like to be able to edit values within that listbox by going there with the mouse cursor and type a new value..
E.g. the listbox displays:
7226218; Hemlock; 22.55; 4
0822722; Pine, Sugar; 11.55; 7
After editing it looks like:
7226218; Hemlock; 22.55; 2
0822722; Pine, Sugar; 11.55; 7
After pressing an "accept button" those values should then be written back to the txt file.

View 1 RepliesI programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.
When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.
Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?
