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)
I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.
I am using a datagridview as an input device. I am using a subroutine to check for errors. When an error is found is there a way to set the focus to the specific cell in the datagridview where the erro has occurred?
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 [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
vs 2005 sql 2005 developer/I have a datagridview with 4 columns .I want the user to be able to use the arrow keys to move through the rows and just two of the columns.I want the other two rows to behave like a label that cannot get the focus. Nor be selected.I have been messing arround with the "cell enter" event but the language wont let me set the selected cell from within that routine.
Is there any way to remove the focus from the current cell after edit when I click the row header? I have tried various methods; repainting the row, cell, moving focus to other cell but the caret still remains in that cell.
I am trying to set the focus in a datagridview's cell after the user enters some data and tries to tab out of the cell. I can't seem to get the focus in the cell they just edited. I can change the background color, but the focus goes to the next field in the grid. I am trying to do this in the _CellValidating event. Here is my code :
Private Sub dgvFish_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvFish.CellValidating
The function CheckSampleNumber() takes the value of the cell just entered, and checks to see if it has been entered either in the current grid, OR in the database.
I am having trouble setting the focus to a particular cell in datagridview.
I have a timetable and on initialisation of the program, it compares the time in the datagridview with the current time. If the time has passed, the row is displayed in grey, if not then it is shown in black. I then want to scroll through the datagridview to focus on the first black line.
Here is the
----------------------------------------------------------- Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" with the note about infinite recursion.
What have I done wrong and how do I scroll through to automatically set the focus?
I have a bound DataGridView where the user should enter an item number in one cell, the name of this item will be displayed in the next cell, and depending upon variables of this item number, the focus should be set to the correct cell on the same row.
My problem is that I can not seem to get the focus to the correct cell.
My code so far. I am having problems with the marked line:
Private Sub dgvOrdreregistrering_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvOrdreregistrering.CellEndEdit
Datagridview . in cell validated handler and I have the column,row for the cell that I just checked on. If the cell contents are bad, I want to force the cell value to be blank and focus back on that particular cell and try again.The code i've tried simply moves to the next cell in the grid instead of staying where I want it to be. Surely there is a command to focus and put the 'cursor' back in a particular cell.Some sample code I'm working with:
MsgBox( "Invalid Job#, Correct or DIE!") JLgrid.Item(0, Row).Value =
I'm reading a cell value from a Datagridview, and this works fine in other projects, but not here?
HTML Dim OldGUID() As String = Nothing Dim X as Integer = -1 For X = 0 To Me.DGView.RowCount - 1 If Me.DGView.Rows(X).Cells(0).Value.ToString IsNot String.Empty Then OldGUID(X) = Me.DGView.Rows(X).Cells(0).Value End If Next
It fails on the line: OldGUID(X) = Me.DGView.Rows(X).Cells(0).Value with: NullReferenceException was unhandled - Object reference not set to an instance of an object. The Cell has a string value and during debug I see the value, but it fails anyway.
I have a one column DataGridView that I use to display data from a database.Is it possible add a command button to one of the cells in that column? I don't want a second column as a DataGridViewButtonColumn. I want the rows containing the database data and the command button row in the same column. Also, if that is possible, I don't want the button's width to be the same as the column's width. Is it possible to manually set the width property?
I'm adding values to a datagridview programmatically (no dataset) according a value in a combobox. In one of the cells (cell is always the same) a hyperlink is displayed. How do I change that particular cell to a hyperlink-cell? If possible of course.
I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?
When a certain form (containing a datagridview (dgv)) is first loaded, the dgv cell formatting event is triggered by the line
dgv_WorkHistory.DataSource = ds_WorkHistory.Tables(0).DefaultView This successfully adds some background colour to a few cells in the displayed table. After this the next line of code is executed. The problem is that if I then try to load a different table (by choosing one from a listbox), the new table displays OK but without the desired formatting. Why?
Stepping through the code I find first of all that when I click on the listbox the dgv cell formatting event is instantly raised (immediately, even before any code in the listbox click event is executed). Why does clicking on the listbox trigger the cell formatting event?
Then, when execution reaches the line quoted above for the second time (remember it triggered cell formatting the first time round) it doesn't this time trigger it. The next line of code is executed instead. Why has the behaviour changed?
I am a tad new to the DataGrid controls, but I am just curious as to why the first code block below works, but the second code block does not? (Only thing I can see is the Handles DataGridClaims syntax
Block 1 Private Sub DataGridClaims_CellContentClick_1(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridClaims.CellContentClick
Essentially what I'm trying to do is to save the value of a string() to a cell in the datagrid view. The problem is that when I close the program and reopen it the changed value isn't there... It's not saving properly.
Here is my code. Dim BOCHURSTOTAL As Double = ((BochurimBindingSource.Current("Give_To_Bochur_Quant") * (bochurpr)) + _ (BochurimBindingSource.Current("Reg_Quant") * (regularpr)) + _ (BochurimBindingSource.Current("Priv1_Quant") * (private1pr)) + _ (BochurimBindingSource.Current("Priv2_Quant") * (private2pr)) + _ (BochurimBindingSource.Current("Priv3_Quant") * (private3pr))) DataGridView1.CurrentRow.Cells("DGV1TotalColumn").Value = BOCHURSTOTAL Me.Validate() Me.BochurimBindingSource.EndEdit() Me.BochurimTableAdapter.Update(Me.PuterDataSet.Bochurim)
I have searched for this, and not been able to find any examples where someone has done this. I'm trying to add a new line into the cell of a DataGridView so the text appears on 2 lines (of the same cell). Here's some code to explain what i'm doing:
Dim DS As New DataSet("aa") Dim tbl As DataTable = DS.Tables.Add("bb") Dim xRow2 As DataRow = tbl.NewRow()
I am making a program which remembers my last selected row in a data table. I have done this by adding a column with a CheckBox, upon CellClick the CheckBox is checked, and upon ellLeave it is unchecked and the new cell is checked, after every action a Update command is run. There will never be more than one row with a checked cell in the DataGridView,however, the data table is in a relationship with other tables, so there may be more checked cells in the data table itself. My problem now is selecting the row with that cell when I open the program and when changing between other data tables and back again.All solutions I found on selecting a specific cell in a DataGridView are referring to index numbers, and in my case I need it to find a data value in a column, I do not know the specific row, only that one row contains the value of True while everything else is False.
I've been trying to customise a datagridview but no luck so far, thing is, i want some of the cells to not have the same grid colour and width as all the rest of the grid. Do you guys know how can this be done? I know it is possible cause i've seen it before but i have no clue how to accomplish that.
I have a DataGridView and want to update the contents of the CurrentCell while the user is typing.e.g. In a cell of fractions I want the user to be able to enter .957 - As soon as the user types the . I want to programatically change it to 0. without the user being aware of the change.
I have been using this code to find the value of the cell in a datagrid view
Dim eRow As Integer eRow = dgv.CurrentRow.Index MessageBox.Show(dgv.Item(0, eRow).Value)
This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function. Checked it via a temp textbox i put on the form. What i actuall want to do is pass it back to another cell on the current row. Tried a few things but having no luck. Here's the code of what works. The name of the cell i'm trying to pass the result back to is called "BaseDec".
