I can do the context menu. When I'm NOT using a context menu, I can detect a right-click using the mouse click event.BUT how do I detect which cell that's beiing right-clicked on in a datagrid WHEN a context menu is being used (as the mouse-click doesn't seem to fire when a context menu is used - so I assume that the menu mechanism consumes the right-click message and doesn't pass it on so to speak).I have tried to manually call the context menu on a right-click, but then the context menu comes up at the wrong location.Rather than send a long listing of my multinedia program so far - here's something I tried as a separate proglet. I can send the long multimedia project listing if you like (so you can see why this it is important to resolve this little issue).

I am trying to discover how to detect that a form has been resized, or rather, that a form is being resized. I need to call a sub to handle the resizing of text in relation to the new size of a form or control. I have found that setting a minimum height and width works behind the scene so I figure there must be something watching the form size but can't find what or where it is.

grd.Columns(c).Resizable = DataGridViewTriState.True
Next c
That allows all the columns in my DataGridView to be resizable EXCEPT the last column. Why?I DO get the little resizable-mouse-pointer... but you can only make the column SMALLER, never WIDER.(Same problem if I try to set all the columns to Resizable, using the VB.net IDE)Shouldn't I be able to resize ANY column I want, bigger or smaller?
I want my program to detect and do something when ToolStripMenuItem is clicked.
View 1 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.
I want to make one Private Sub for all of my Linklabels. The only variable should be the text value of each individual Linklabel, since all the labels inherit different texts during my program.Lets say I have about 200 Linklabels of which 40 have specific texts. The other 160 have "Linklabel" as a text.How can I create a variable that refers to the text of the label in the code?
Would it be something like this?:
Private Sub ActionForAllLinkLabels(ByVal something As something, ByVal somethingelse As somethingelse) Handles LinkLabel1.LinkClicked, LinkLabel2.LinkClicked,

View 2 RepliesI'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.
HTML
Private Sub HistoryTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HistoryTextBox.TextChanged
If ugHistoryButton.ActiveRow.Cells("Dog").Selected = True Then

It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.
Is there a way to detect when a label is clicked without doing on click events for all the labels? I want to be able to detect the click, find what has been clicked, then I can change the label since I'll know which one has been clicked.

View 1 RepliesI 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
[Code] .....
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
End If
End Sub

I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?
how do I get the Header text of the header the user clicked in the datagridview.I know I have to use the column header click event but I can't work out or find away to extract the clicked header data?

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 already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

View 2 RepliesI'm using the MouseDown to create objects, they are used within MouseMove and they are killed within MouseUp Event. Now I want to use the Doubleclick Event to build in some shortcuts. My problem is that the MouseUp routine is called sometimes before the DoubleClick routine. I do need the MouseDown Event before starting the DoubleClick code, however sometimes the MouseUp event is triggered which is killing the needed objects.
Is it possible to get the DoubleClick-event routine always without the MouseUp routine?
