Don't have Click event in TextBox in WPF C#

I just want to add simple thing, wherever i click on TextBox I want to delete text that is inside. The thing is I DON'T have in list of events, event called Click.. Is this even possible? Or just I need to install some add on. Buttons are fine, they have Click event.

MouseButtonLeftUp would work if you only are concerned with mouse clicks. With that said, what if someone tabs into the box or focus is entered by other means?
At that point you may want to look at the GotFocus event. Any time the TextBox receives focus, you can handle the event.

TextBox has events called MouseLeftButtonUp and MouseLeftButtonDown, you can use them.

Click Event not firing if it causes a CellEndEdit Event

I've a DataGridView where I'm showing some results that can be edited by the user, there's a save changes button that will update the database according with anything the user has input. I've checked that if I edit a record, make focus in another component and click the button changes are saved appropiately. Problem is that if I have a cell where the cursor is on, move directly to the save changes button and click it the only event that's fired is the CellEndEdit event, which would register there's a pending change, but it wouldn't update the database, opposite of what would be the expected behaviour, so the user would need to press the button again to do the changes.
Any idea on how to fire first the CellEndEdit and then the Click event in this situation so the result would be the expected one?

I finally got to solve it by checking on the CellEditEnd event if the save changes button is focused or not, if it is, I get to make all the save procedure, I think it should fire both events anyway, but as long as it works I don't care much.
Thanks for your tips, as they helped to guide me.

Must click a button twice to fire an event

I have a data grid that is created dynamically to display information retrieved from a database. The data grid consists of multiple bound columns and two button columns for each row, a view and a delete button.
Clicking either button calls the Page_Load() method with Page.IsPostBack as false.
if (!Page.IsPostBack)
{
this.bindForm(); // Populates drop down lists that the user can select
setAccess(false); // Sets access for the page
// Stuff commented out to avoid confusion
}
else
{
bindDynamicGrids(); // Create the data grid(s) and populate them
}
So when I first click the button the above code gets called with IsPostBack false, and the dynamic grids get bound. But, the button click event does not fire. When I click the button a second time, Page_Load is called with IsPostBack false, and after executing bindDynamicGrids() the button click event is fired. I cannot understand the difference between the first and second click.
I have read a few threads;
ASP.NET C#, need to press a button twice to make something happen
http://forums.asp.net/t/1783694.aspx?ASP+NET+Button+needs+to+be+clicked+twice
To attempt to understand the issue, but I must be missing something. From what I am gathering from the second link, a session variable may be getting set in the click event, which is also being set in Page_Load, and this is all an issue with ordering. If that is the case I am not seeing where it is happening.
When it is not a post back the bindForm() method is called, which populates all drop down lists. The edit click event populates those drop downs with the values from the row, but the click event is always a post back and the form has already been bound.
I have also considered having a script automatically double click one of the buttons anytime the user single clicks, but I have not been able to find an "OnClick" property for the column button. Any help that could be provided would be phenomenal.

The thing is, that the button click event happens after the Page_Load event meaning that the filtering does not get applied on the first postback. It has been updated on the second postback and you see the filtering.
You can try to move the code of your page_load event to OnPreRender so the reload happens after the button click event.

TextChange in Gridview Textbox prevent button event

I have a text box on a Gridview which I'm allowing some data to be edited. When the enter key is hit, the TextChanged event happens, like I'd expect. But when i change the data and click a button, the button effect not happen. I must click the button again to fire button event. I think it happen because the grid didnot lost it focus.
How to make it possible fire the button event just in one click?

You can change your gridview element's IsTabStop property to false to gain that effect.
Also if you want to cycle with Tab you can TabNavigation="Cycle" .
Both changes are in xaml.

Not much we can do to help you here without the code itself but here are couple things you could try to debug this:
Try different browsers – it may be a browser issue
Try some client side debugging – just open console and see if anything happens when you click the button for the first time

C# Datagridview SelectionChanged Event fires earlier than I want it to

I'm working with Windows forms. I want an event to fire when the user makes a selection of cells (or one cell) in the datagridview. The SelectionChanged Event is firing as soon as I select one cell. Is there any way to have it wait for the user to be done selecting?
I have tried the CellMouseUp event, but I don't like its behaviour because if MouseUp happens outside the grid it doesn't fire.

As they select each cell a new selection change should be fired. so you are looking at "remembering" the selected cells each time the eventhandler gets triggered and then doing your processing based on that.
How much of a pain this going to be depends on what processing you are doing with the selection. Could be a good deal.
