Asp.net - .NET Textbox Changed But Still Hold Initial Value?

Apr 5, 2010

I've never come across this before:I have a series of text boxes. The text of these boxes get set on page load. then I have a submit button that calls a sub to update the table with the new values (text) in the text box. The problem is it is keeping the original text not the text that is CURRENTLY in the textbox. Anyone come across this before? Or know how to get round it?

VS 2010 : Set Initial Value For Textbox As Blank?

Jan 16, 2010

how do i set my initial value for textbox as blank. I tried to I load my textbox a data coming from my database but what my problem is that I need to set my default value for textbox as blank because everytime I load the forms the textbox will be filled immediately with data.

cbxJoblvl.DisplayMember = "Joblevel.lvl";
cbxJoblvl.SelectedIndex = -1;
txtLvlName.DataBindings.Add("Text", myDataSet.DefaultViewManager, "Joblevel.lvlname");

VB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK

May 5, 2012

I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"

VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.

The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'

Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.

I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

Saving Changed Data Before DataViewGrid Selection (Row) Changed?

Jan 20, 2010

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

What Event To Use When Loading Initial Data

May 23, 2011

I'm writing a forms application. I'm adding a piece that allows you to double click on a row of a datagridview control to open a new form with more details. These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?

DatagridView - Initial Load Formating

Jul 5, 2011

I have a datagridview and need to do some formatting to it. On load the row 0 column 0 cell is highlighted. I need users to click on datagridview to select a value. The issue is with the initial load highlight it looks like the first row is already selected when in fact it is now. How can this highlight be disabled? Each row of has 7 cell, the user is able to select any of the cell of a row and the corresponding row ID is selected. The issue is that only that one cell is highlighted.

I would like the entire row highlighted regardless of what cell in that row is clicked on. One of the columns is a status value. I would like to color the text based on the value. For example if the Status is opened I want the text to be red, if the status is closed the text color should be default.

If Statement To Check If Value Is +-1 Of Initial Value Held In A Var

Mar 9, 2012

I need to run an If Statement that will check a few conditions.

Basically I want to get it to check a value held in a variable "Temperature" and if the value is within "1" eaither way i.e. +-1 of the value held within the variable to then to output a text string to Label200.Text Else if the condition is not met then out put another text string to Label200.Text.

Example:

Say if Temperature value held in the variable Temperature is 8.5 the if statement checks to see if the DewPoint value is "between" +-1 of the temperature value. i.e. 7.5 to 9.5 as well as the value in Humidity is equal to or greater than 90 and Pressure is Less than or Equal to 1013.25 then the conditon is met, else the conditon is not met.

I have put some code together below in NotePad++ to see if what I am trying to do is the correct way to go about it (note I have not yet tried this code in VB.NET as I don't have it at work).

pass comment on the code and if it is wrong explain what I should do to get it to work.

Dim DewPoint as Single
Dim Temperature as Single
Dim Humidity as Single

Initial Event In Windows Console

Aug 28, 2009

I'm creating a Windows Console application written in VB.NET and I have a few processes that need to be called only once during the lifetime of the application. If it was an ASP.NET application, I put these in the Appliction_Start method of the Global.asax.vb file. Since there isn't a Global. asax. vb for Console applications, is there an event I could handle that allows me to call my functions before Main is called?
