I am overriding the OnRenderButtonBackground method in order to use custom colouring, but I want to know if the mouse is currently over the button. I tried to get the parent control (the toolstrip) and the parent form and add all the co-ordinates together but this is not correct:

View 2 RepliesI have a toolstrip in my main form, at the bottom. The main form has menus that lead to other forms. I am trying to get a button to appear on the toolstrip each time a form opens. My button creation code works. Here is what I have so far:
Public Sub buttons()
'Each form has a Me.FormClosing and MyBase.Load event that links to this sub.
ToolStrip1.Items.Clear()
ToolStrip1.Items.Add(ToolStripDropDownButton1)
For Each frm As Form In My.Application.OpenForms
[Code]...
I have tried using the Tag property to choose the form, but it hasn't worked.I have also tried using the My.Application.OpenForms property to open the form, but this also hasn't worked.I really don't fancy using loads of If Then Else statements to hide and show buttons that have already been created, as this seems rather messy.
I have a textbox, a standard button and a toolstrip containing a couple of buttons. In the validating event of the textbox i coded to check whether it is blank. If yes then it shows a message 'Enter Value'. When the standard button is clicked while the textbox is empty, it's validating properly and showing the message but when the toolstripbutton is clicked it's not not validating the textbox and no message is being shown. It seems that I gotto write the validation code explicitly in the toolstripbutton_click event which is too troublesome when there are multiple textboxes and toolstripbuttons on a single form. What I want to know is whether the textbox_validating can be fired while the toolstripbutton is clicked? Handling toolstrips is really a headache. I'm badly in need of it.

View 2 RepliesI'm making an MDI child window switcher (to set focus on selected child) sort of in a windows-style taskbar at the bottom of the program. I've got things set up so that when a child window is opened, a toolstripbutton is created and added onto the toolstrip and contains the window number and window type (what the window does). All that runs very well, but when I want to close a child form, I need to dispose the button that corresponded to it. I tried something like this:
For Each C As Control In frmClient.Controls
If TypeOf C Is ToolStrip Then
For Each tButton As ToolStripButton In C.Controls

View 6 RepliesI have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.

Some of my DataGridViewCells return the wrong value in their GetClipboardContent method. They are cells in a DataGridViewComboBoxColumn cells, so they use the displayed property, not the value property of the cell. I want it to return the value itself.An initial attempt was simply using
Protected Overrides Function GetClipboardContent(ByVal rowIndex As Integer, ByVal firstCell As Boolean, ByVal lastCell As Boolean, ByVal inFirstRow As Boolean, ByVal inLastRow As Boolean, ByVal format As String) As Object Return Value End Function in my DataGridViewComboBoxCell descendant but then I noted that this method is called more than one time per cell value, once for every data format DataGridView supports by standard, which are format="HTML", "Text", "UnicodeText" and "Csv". For csv, the base implementation appends a comma if it's not the last cell, for html it adds the correct tags depending on if it's the first/last row/cell in the table/table row, etc. I consider this format-specific, not cell-value specific.
So how could I replace the value that ends up in the clipboard without re-implementing all those format-specific aspects? That would result in quite some code for functionality that already exists in the base class, wouldn't it?
I have a theoretical class Name_Order, that has a string Name and a int Order. I need to indicate that two Name_Order's are different, if the pair NameOrder is different, that is, or name or order are different. Now, overriding Equals no problemo, but I have some "issues" with GetHashCode:

I have a main class that has a Sub procedure with no implementation. Any derived class should override and implement this procedure, so I used MustOverride in the base class.
Now, any time this procedure is called, I need to set a specific Boolean variable to True at the beginning of the procedure and set it to False at the end.
Is there a way to avoid writing these two lines of code in procedure implementation of every single derived class? Can I set this value to True in the base class, then run procedure in the derived class and then set the value back in the base class?

View 1 RepliesI inherited DataGridViewTextBoxCell because I need to add some custom property to it.
At run-time after creating the DataGridView instance and bind the data I do the following:

If k > 0 Then grid.Columns(k).CellTemplate = New CustomCell()

the cell type is never of type CustomCell but it remains DataGridViewTextBoxCell.
