Re: Get Datagrid handle and get invidual cells handles

Thanks for you reply.

Sure. I will tell you the complete matter...

I'm working with CCF 2008, then i have an hosted application and this launch any actions at double click on a specific datagrid. I build a global hook to trap double-click event on datagrid and get the row (by the handle). But on debug, the returned handle not corresponding to datagrid even a SCROLLBAR. i don't understand. It works fine at another controls, on textbox, on forms, but not on datagrid.

There is the code line;

private void MouseHook1_MouseDoubleClick1(object sender, System.Windows.Forms.MouseEventArgs e)
{
///It call, is only for get the control caption. But obviously there not have, because it is a scrollbar!!!!
StringBuilder build = new StringBuilder(256);
OpenWindowGetter.GetWindowText((IntPtr)sender, build, 256);

///Here, i call the method that get the child controls captions (or classes names)
List<string> strHijos = OpenWindowGetter.GetChildWindows((IntPtr)sender);
....
}

And ever, this return SCROLLBAR in generic list.

Please, tell me if you want to view more code.

Oh. Sorry for my english. I'm not too expierenced with it. Blush | :O

Do not apologize for your English, it is fine.

If it is the case that you are expecting strHijos to be filled with the handles for the cells of the datagrid, I believe you are destined for disappointment. GetChildWindows is returning the only child window of the grid, its scrollbar, since this is the only thing that has a handle.

I believe, although I could be wrong, that the grid controls do not create a window for each cell, they just draw a cell-shaped representation at the place where each cell should be.

For your future reference, if your first message had been like this one I'm sure that you would have had a more helpful reply than I am able to give here. Also, although I don't think it makes a difference in this case, you should make it clear if you are using a DataGrid or a DataGridView.

Hopefully, someone will be able to come up with an idea to help you.

Good luck!. Smile | :)

Thanks again.

That's right. It's the only handle returned by DataGrid (not gridview, not DataGridView). By other hand, when i clicked (single-click) on cell to edit, the hook that trap mouse-click event, i got another handle, i find it by another application (to get windows and controls list) and it return that it handle correspond to "EDIT" class name it means that exist a handle for each textbox, listview, or any control into datagrid?

Thanks to Henry for give me a clue, and if anybody can help me, thanks in advance too.. Smile | :)

Events

Is this possible: I have a form with a datagridview. I have an event handler for the grid's CellEnter event but this event is fired before the form's load event. I have a break point at the form's load event and one at CellEnter but the CellEnter is handled before the form's load event.

Also, does anyone know the tool (I think it comes with VS2005) which shows all events as they occur?

I understand when it occurs, but shouldn't the form's load event occur prior to all the children's events? DataGridView is a child of the form.

I think you are getting this error because you are not adding a root element.

Hi all,

I have a library with a couple of methods. I make use of the xml tags to comment the method.

/// <summary>
/// Executes the command.
/// </summary>
/// <param name="Command">The command.</param>
/// <returns></returns>
public bool ExecuteCommand(string Command)

The problem is as soon as I compile the code and use the library in another project, none of the comments displays Confused | :confused:

How can I fix this.
Many thanks in advance

Kind regards,
