I have a DataGridView that based on certain conditions certain columns or rows or cells need to be locked/disabled but the data in the columns or rows or cells needs to bvisibleNow let me define what I mean by lock/disable; the user cannot click on any cell that islocked/disabled, if the use is using the arrow keys the selected cell cannot move to a locked/disabled cell.So this means that setting the cell as read only will not work, the user can still place the cursor on that cell.
Private Sub DataGridView1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged
If DataGridView1.CurrentCell.ColumnIndex = 0 Or DataGridView1.CurrentCell.RowIndex = 0 Then

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)
[Code].....

I'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
[code]....
It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.

My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]

I'm having trouble with setting a datagridview's cell in edit mode, or rather, to let the user type some input on load of a form (as in Excel or the like).
This is my code (after the dgv has been filled):
dgvTentander.EditMode = DataGridViewEditMode.EditProgrammatically
'(or dgvTentander.EditMode = DataGridViewEditMode.EditOnEnter)
dgvMyDGV.CurrentCell = dgvMYDGV.Rows(lastrow).Cells(TeCOL_Quant)
dgvMYDGV.BeginEdit(True)
The code correctly indicates that the cell is selected, and when the page is loaded I can still se the cell selected, but the cursor doesn't appear and nothing happens when I type.

I've been looking everywhere for an answer to a simple question, but i'm having issues, so i thought i'd join and post here. I'm having issues with a simple concept. I load information from a SQL database, and i want to add a 'Passport' link URL relating to column cells called 'name'. It basically selects the name, and inserts it into the link fields to be opened. But i cant find a way to work it. I thought i could do it with something like:

The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.
The highlighted part of my code is the text closed in quotation marks.
"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True
End If
This code is under my dgv cell click event. Here is a screenshot for the column header where I found the error. [URL]

I have two forms in my program,on Form1 there's DataGridView and it shows the content of my database,on my Form2 there's few textboxes and listboxes. Wen you select row on Form1.DataGridView and double click the row header it pops up Form2 and shows the info of that previously selected row in those textboxes and listboxes.
Now with some help,i've managed to understand how to do that,but how to make those textboxes and listboxes connected to that row also?
I mean when i enter something in textbox it brings back the value to corresponding cell(to that cell of which value was shown in the textbox). Or how to make that textbox connected to the same row directly in my database itself(probably worse scenario,since any time i type new vallue and hit enter ir will connect to database,other way the value in DataSource will only be changed,it would take less resources and time probably?)

I have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.
Here is my code
strOriginal = dtbExcelData.Rows(0).Item(0).ToString
y = strOriginal.IndexOf("@")
strA = strOriginal.Substring(0, y - 1)
[code]....
For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.

I have a form where a number of textboxes are programmatically created within a flowLayoutPanel and named by adding together 2 strings.
With the click of another button i hope to have all the values entered into these text boxes stored in a text file. However, i cant seem to find a way to add strings together to allow me to retrieve the values entered within the text boxes created.
Below is the code i have so far: BTW FLP is my flow layout panel and c is my calculated nmber of textboxes that are created.
Private Sub createTB(ByVal c As Integer)
Dim x1 As Integer = 1
Dim y As Integer = 2

I am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4. The catch is I don't want it to update every time the sheet is recalculated due to updating links in other cells on the sheet. ONLY when Cell A4 Changes. What do I do?
