Then this dynamic temporary DataTable is saved in a ViewState variable and finally it is used to populate the GridView control. Note : You can also make use of Session variable if you need to use the temporary DataTable across the whole application.

Since we are attaching the event directly to the GridView Row which by default does not have any OnClick event, you might land into the following error. Invalid postback or callback argument. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.

Thank you for the feedback.Occurs when a row's Delete button is clicked, but before the GridView control deletes the row. The following example demonstrates how to use the RowDeleting event to cancel the delete operation.

The page contains a GridView control that displays a list of customer names and addresses from the AdventureWorksLT database. When the user clicks the Delete link for a row, the handler for the RowDeleting event checks the last name of the person displayed in the row that the user is trying to delete.

If the last name is "Beaver", the delete operation is canceled, and an error message is displayed. For any other name, the delete operation proceeds and the row is deleted. The example examines the contents of the Rows collection. If the value you want to compare to is a key value, you could examine the DataKeys collection instead.

Rows are deleted from the CustomerAddress table instead of the Customer table in order to keep the example simple. When a CustomerAddress row is deleted, the corresponding GridView row disappears. Referential integrity constraints would make the code for an example that actually deletes rows from the Customer table more complex.

NET Development. The RowDeleting event is raised when a row's Delete button is clicked, but before the GridView control deletes the row. This enables you to provide an event-handling method that performs a custom routine, such as canceling the delete operation, whenever this event occurs. A GridViewDeleteEventArgs object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the delete operation should be canceled.

You can also manipulate the Keys and Values collections, if necessary, before the values are passed to the data source. For more information about how to handle events, see Handling and Raising Events. Skip to main content. Exit focus mode. Grid View. WebControls Assembly: System.

View this topic on docs. The following RowClickEventArgs properties provide information specific to this event. Property Description Button Gets which mouse button was pressed. Clicks Gets the number of times the mouse button was pressed and released. Delta Gets a signed count of the number of detents the mouse wheel has rotated. A detent is one notch of the mouse wheel.

Handled Gets or sets a value specifying whether an event has been handled. HitInfo Gets an object that identifies the clicked element. IsHMouseWheel This member supports the internal infrastructure, and is not intended to be used directly from your code. Location Gets the location of the mouse during the generating mouse event.

RowHandle Gets the handle of the clicked row. X Gets the x-coordinate of the mouse during the generating mouse event.The DataGridView control generates many events as a user navigates the grid.

To make best use of these events, you'll need to know when they occur, and what happens when you respond to these events in different ways. This article provides:. Buttons are also provided which allow you to affect the behaviour of the event handlers. For example, a different sequence of events may be generated when a cell fails to validate. Changing those validation responses is just a click away. The executable is provided in the download, so it's simple to try it out and see what events the DataGridView is firing at you.

I haven't supported every grid event, the log would be less useful if it were clogged up with all of them, but I've included the major navigation and validation events. Adding new handlers is trivial and explained below if you need to do it. Let's take a look at the application first, then I'll describe the events in more detail and introduce the state machines. The application contains an event log, a grid, and a tool bar.

As soon as you run it up, grid events will fire and those events will be displayed in the log. Click on any cell in the grid and more events will be added to the log. The toolbar buttons can be used to simulate responses provided by the validation event handlers. The code isn't complicated, and I'm not intending this article to be a grid programming tutorial so I won't go into it in detail.

In EventGrid. If you're not interested in the events I've supported, just delete the handler. If you want to support others, add a handler for the new event and follow the steps above. Let's take a high level view of the event sequences and follow it up with a description of the state machine included in the downloads. There are several variations to the general case, but let's start by assuming that the grid edit mode DataGridView.

EditMode is EditOnKeystroke and that all cells, all rows, and the grid, are valid. That allows navigation of the grid without slipping into edit mode.

As we move from one cell to another, we see in this order :. The OnCellLeave event will always occur when an attempt is made to navigate away from a cell.

Additional Leave events may occur, depending on where we move to. For example:. Leave events are straightforward, in the sense that future events are not affected by any change to arguments in the Leave event handler.

When the Leave events are complete, the Validation events will start to fire.

You'll recognise the order from above. Everything validated, so the cell focus can move as intended, and the event sequence completes by firing the Enter events for the new cell.

Put all that together and when moving from a valid cell C1 in valid row R1 to cell C2 in row R2, the following sequence of events will fire:. Now as mentioned, that's just one case and there are many variations, so let's follow this case i. Begin at state 1 in the top left of the diagram.

In this state, one of the cells is selected but not being edited. When a cell on another row is selected, the transition to state 5 occurs. Now looking at FSM A2, from state 1 assuming the OnCellValidating handler indicates that the cell is validthe transition to state 2 occurs.
