Set Focus To Editing Row

Dec 14, 2009

How do you set focus to a specific control in a datagridview row after clicking the edit button? I'm able to do it for a new row when the grid is binding, but not for an existing row. The control doesn't seem to exist yet.[code]

Forms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?

Feb 16, 2011

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Window Focus - Right Click On The NotifyIcon, Excel Gains Focus?

Mar 10, 2009

Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.

Forms :: Form Losing Focus - Keeps Loosing Focus ?

Nov 26, 2009

I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.

The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

Lost Focus Event, What Control Is Getting Focus?

Mar 21, 2012

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!

So for example something like this...

Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

Editing Row Of A Datagrid In ASP.Net?

Jan 12, 2010

I'm working on a piece of code at the moment that uses an older style DataGrid to allow the user to enter information into the table. It already has an add and delete button. Currently the user enters information into 3 textboxes that are in the footer, and the other rows use labels to display the information.

Essentially what I am wanting to do is take the line that the user has clicked the edit button on, and move the text from there in to the footer (deleteing the row that it was displayed on) so the user can make changes and then click the add button again. At the moment I have tried using FindControls to find the textbox and setting the text that way but it doesnt like it.

.Net Editing A CSV (or Delimited File)?

Jun 15, 2012

I would like to know a way (of course I want to know the best way) to edit a csv file, preferably without having to read the original and write the results to a new one.

Example 1: I want to split the contents of a column into two columns 123abc into 123, abc

Example 2: I want to remove letters from the beginning of a column AB123 into 123

Clarification: I do not need help solving my examples; I just need to be pointed in the right direction of reading and editing the same file.Here is a code example of using a temporary file that seems to me is too slow

Dim currentLine as string()
tempFile.AutoFlush = True
Do Until origFile.EndOfData

C# - How To Do Multi User Editing

Jul 21, 2011

I have a system where I would like to show a warning to a user if there try and edit a record that is currently been edited. If this is the case the user will not be able to save the record but only view it.I have an idea of using some kind of class to monitor the activity of records been edited etc but this seams a little over kill. My other concern is that what if the browser crashes or there shut their computer down on how this will effect the state of the page.

Another thought was to use last updated time stamp but this also looks a no go because the way records are been updated? how I could implement something like this. No code is necessary.based on the comments I have added these additional details.database is SQL server 2008 asp.net 3.5 one record could be many parts of the database for instance, the booking table session table and a row in the interrupter table.the user will look at a list of sessions that need booking select a booking and fill out a booking form to make the booking. Want to stop is someone else trying to do the same booking at the same time or while someone else is doing the booking.
