View 12 RepliesI have a program with 32 PictureBoxes (pb1 ... pb32). The user will select one of the picture boxes. All picture boxes will call the same subroutine, passing the variable of the name of the box clicked. Rather than writing a click event for all 32 boxes, and call the same subroutine from each event, is there a way that I can determine which picture box has been clicked?
View 3 RepliesIs there a way to determine is any control at all on a form has gotten focus? I know you can individually determine if a single control has focus or has been clicked, etc. but is there an event that can tell you that some/any control has been clicked?
i.e.
Private Sub myFrm_Magic(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.SomethingClicked
Msgbox(Me.ActiveControl.Name)
End Sub

I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens.
Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever().

I have a datagridview that I have put a ContextMenuStrip1 on. I would like it to remove a row in the datagridview when the row is right clicked on and they click on "delete row". I have the delete working and the menu is showing up but this isn't firing when you right click on the datagridview.
This is where I am setting the row to edit:
Private Sub ModifyRowToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ModifyRowToolStripMenuItem.Click
If Not datagridview_TagAssignment.CurrentRow Is Nothing Then

I am always ending up on row(0) and never the row I right clicked on.
Private Sub datagridview_TagAssignment_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles datagridview_TagAssignment.CellMouseClick
If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then
datagridview_TagAssignment.Rows(e.RowIndex).Selected = True

This is my first time using the checkbox in a datagridview. I added the column at design time and it is false for readonly and frozen. But when I click on it at runtime nothing is happening. Do I have to check it through the event?
View 2 Repliesi need to know exactly when a checkbox is checked either by clicking or by spacebar.
I have looked at cellbeginedit, cellclick, cellcontentclick,cellendedit,cellformatting,cellleave,cellpainting,cellvalidating,cellvalidated,cellvaluechanged, and cellvalueneeded.
None of these inform me of when the checkbox value is changed. cellclick is almost the one, but it fires before the value is changed. cellvaluechanged doesnt fire until you leave the cell. the cell value changes and the cell is painted even if you dont leave the cell.
I have spent all day trying to get it right. I want to detect exactly when the checkbox value is changed so i can do some calculations and depending on the calculations, i may cancel the check mark.
How can i determine datagridview 's datatable change or not when i leave it.
If datagridview change then my value return true else it ll return false.
I have a loaded DatagridView which contains a row/column with an employee number in it. Outside of the DatagridView at the the top of my form I have a small PictureBox. My goal is for the user to select the employees row (not cell),pull the employee number from that row/column, and then use a LINQ query against another table to display the image stored in that table.
Determine the event needed in the DatagridView?How do I pull the employee number from the selected row?What considerations, if any would the LINQ query need to pull the picture from the table?
I have a datatable with 10 records linked to a datagridview. When I initially load the datagridview, row 0 in the datagridview = row 0 in the datatable - based purely on the order they load, and the datatable's default sort order. I then filter my datagridview and am left with 5 records. Is there a way of determining programatically, the actual datatable row number of a row displayed in a datagridview, considering that row 0 in the datagridview is now not necessarily row 0 in the datatable?

View 1 RepliesI'm pretty new to VB.Net programming, but have already been able to figure out many things using this forum, but also via the many other forums on the internet.I'm currently stuck with a question though regarding getting the clicked value in a datagridview comboboxcolumn.When I use _Selected IndexChanged and then check the current cells value, what I get is the value before I clicked the new one in the comboboxcolumn.When I use _CellEditFinished, I can get the new value, but only after I selected another cell, or changed focus to another object.How do I get the new value from a DataGridViews ComboBoxColumn the moment I clicked it in the pulldown menu from the ComboBoxColumn?

I have a calculate button that, if clicked more than once adds the total of what I previously had to the new total as I am using a loop. I was thinking that I could get around this by only allowing the button to be clicked once, and if the user attempts to do this more than once a messagebox will appear saying that you can only calculate the price once and the form resets but i can't seem to get any code working.
