I am trying to get the value from a field in my Access DB.Once the value is retrieved I need to be able to compare it to a condition I set. I still haven't figured out the right code to make this happen....i don't know if I should convert something or what,heres my line of code...
ElseIf Me.AssociateDBDataSet.Associates.Rows(0).Item(4).value.ToString = ("No") Then
MsgBox("You are not currently scheduled for Training! Please see your Trainer.", MessageBoxIcon.Stop)
The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
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.
I am trying to access a value of gridview cell , multiply it by 2 and then set it to another column. My code is below but i am getting the error "Input string was not in a correct format".
Basically, I've made a dataset with a table inside of it that I plan on using for a quiz program.
If it matters, heres the code that was generated when I did this.
vb Private Sub QATableBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Me.Validate() Me.QATableBindingSource.EndEdit() Me.TableAdapterManager.UpdateAll(Me.Database1DataSet)
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?
The issue is whenever the user selects an item in an comboBox , the cell adjacent to the comboBox must act as a textbox containing by default as "Enter the Value" in transparent mode. when the clicks on it the default text has to be sqiped off and the cursor must blink at the beginning of the cell.
I have a data grid view and i want to show the text from the first column of the selected row (regardless of what cell in that row is selected) in a text box.
So for example in this picture:
The 1st column of the selected rows text is 'California' so that should be sent to the textbox.
I have a datagridview which I would like to change the the color of the text in a cell if the number is negative in the Total column. This is what I have so far.
Dim rowcont As Integer = (TTLGrid.Rows.Count) - 1 For x = 0 To rowcont Dim Total As String = TTLGrid.Rows(x).Cells(4).FormattedValue
I am new in VB2008. How I can programmtically delete/remove/clear the content of a cell of DataGridView? Say, for example, I have the following code that populates with data in DataGridView. Now,how can I clear/delete the "Test4" text from the cell of DataGridView? The GridView is not bound to any database.

I have one DataGridViewComboBoxColumn in the DataGridView, and that column's "ValueMember" is the "id" and "DisplayMember" is the "name" of my table. When I try to read the text with cell's "value" property, the "id" is returned instead of the "name". Is there a way to read the "name" or "DisplayMember" of a cell in DataGridViewComboBoxColumn?
I've got an unbound DGV with several columns that I am programmatically adding rows to. All working fine, apart from when I try to set a really long string in one of the cells, then that cell just appears blank. The string IS in the cell because if I select the cell and do this:
[Code]...
then the string gets copied to the clipboard and I can paste it into Notepad or whatever without a problem. So it is just purely a display issue... but it doesn't seem to make any difference if I resize the cell (horizontally or vertically) and I can't understand why it is doing this.
I'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String For Each dgvr As DataGridViewRow In myDataGridView.Rows customer_name= dgvr.Cells(2).Value '.... next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
write a macro that removes the letters "TBD" from any cell it is in in a range of cells (J5:PJ421)n a different worksheet. This is probably very simple, but I am new to VBA and can't figure it out.
i am developing an application with vb.net incorporating a Datagridview control. i know that we can make a particular column as checkbox column or text colum or button column. Is there any property/method to make one cell as checkbox cell, other as text cell and another as buttton cell for particular column within the DGVW?
I want to display image next to the text in each row in a datagridview. I have searched the net in the past 1 hour, but no big success. I know, that I must override the cellpaint event, but how?
Does anyone know how to highlight or change the color of text inside a datagridview cell? Not change the back or fore colors of the whole cell, but only for a particular word inside the cell. This is to make the search results more visible to the user.I tried doing it in the Cell_Formatting event of the datagridview but I'm only seeing options to change values of the entire cell (e.CellStyle). If there was only a way to select text inside the cell and set the selected text's properties. Or if I could use some formatting tags around the text.
What I need to do is if the table has a row then copy the text out of a cell to a radiobutton. The text I have so far is: If EXISTS(ds.Tables("DogBasic").Rows(0).Item("DogName")) Then RBDogName1T.Text = ds.Tables("DogBasic").Rows(0).Item("DogName").ToString Else RBDogName1T.Text = "Add Dog" End If [Code] .....
But I get an error: Error 1 'Exists' is not declared. It may be inaccessible due to its protection level.
The code below works for clicking on a cell and showing the text in the proper textbox. I am monitoring cell 0 and 2-5. The problem is when I sort the database by clicking on one of the headers that is monitored, the program shows the below error. The error corresponds to the cell position that is monitored. In other words if I sort on the first column (0) then the error is associated with the following [code]....
Every week I generate a CSV report that adds an extra space to the beginning of my date column. Because of the extra space, Excel recognizes the date as text and will not format the information as a date. I have tried the Right() function but once Excel recognizes the date as text, it will not convert to a date. Can I programmatically address this issue in VBA and how?
I'm adding a textbox to my grid as follows and formating it as a date.But reagrdless it doesn't seem to want to format it as a date.Further how would I prevent, for just a single column, the user from entering anything but numbers and "/"'s?[code]
VB.net VS2008. I have DataGridView AutoSizeColumnMode set to AllCells which works perfect except I need a little more space between all text. How can a use AutoSizeColumnMode but add the same amount of space between the text and the cell border?
What im trying to do is, when I click on any row on my datagrid(dgvCompositions), all the cells(16 columns excluding ID column) in that row must be loaded into the 16 textboxes I have (txtB1, txtB2, txtB3....)
So when I click the row, and the entire row is highlighted the text from the cells get loaded into the textboxes.
I know how to pull data or text from specific cells clicked
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick TextBox1.Text = DataGridView1.Item(0, e.RowIndex).Value End Sub
But the problem I have is that how do I pull all 16 simultaneously and put them into 16 individual text boxes?
