Forms :: Leave Not Being Triggered On Buttonclick (cursor Is Not Moved)

Oct 5, 2010

I am having a problem where I am on a text box and try to click a button that will bring up some reports. Since my cursor is still on the text box it doesn't go through the "Leave" and so what I entered into the text box is not saved (this happens in "Leave"). I have read previously not to use "Lost Focus" because it causes problems when you leave the form it triggers the "Lost Focus" on on the fields and just in general to use "Leave" rather than "Lost Focus". Is there a way to force my way through the "Leave"? I also don't know which field my cursor could be on (there are probably 20 text box or combo box fields on this form.

IDE :: Grids Contain Only Four Columns Each - Get The User To Be Able To Click On A Cell And Populate Four String Variables?

Nov 11, 2009

I am using Visual Basic.Net 2003 with an Access 2000 database.

An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.

1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.

2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.

Datagridview Changing Cell Values On Leave?

Jun 5, 2011

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.

I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.

I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.

I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.

It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).

Textbox Will Not Let User Leave Unless Data Is Entered

Jan 10, 2012

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

Customizing The DatagridView - Navigating The Cursor Into A Particular Cell?

Jan 11, 2010

We are using the DataGridView Control for our projects. The Applications we are developing is the replacement for the Existing CLI (Command Line Interface Applications) written using FoxPro.The users are much more familiar with the Keyboard Navigations ratherthan using Mouse and all.Here What we need is, how can we handle the Keyboard Operations in the Data Grid View. Some of the Operations i am listing below.When we hit Enter Key :

1. Navigating the Cursor into a particular Cell (It will be in the Same Row, but Different Order), after getting focus the cell should become editable

2. Navigating the Cursor to the Next Row and First Column (Once i finished the editing in the Last Column )

3. Focusing the Cursor into a Specifc Row and a column. (With Editable)

Jul 1, 2010

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again.

This is what I have coded, but like I stated there are no code errors.

When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).

I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
