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 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.
And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.
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 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
in the GotFocus event of that datagridview.But when i run and try to enter some text in a cell, then press the DOWN button to go to the next cell but there is a NullReferenceException.
I can Highlight the row in a datagridview. If I don't scroll down a few hundred rows. I will not see it highlighted. How can I automatically scroll to the highlighted row?[code]...
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
[Code]....
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
[Code]....
"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
i want to know the value in the specific cell,let say there has 3 columns and 3 rows,i want to know the first column and second row cell value in datagridview that bind to a database,can? i want to use that value to to something.(*the cell is not the selected one)
I have a main form with a DataGridView populated from an Access Table.So far so good.When the user clicks on a row a small form pops up and the the user can enter/edit for 2 specific fields .After that hitting the save button an update query ensures that the data are written back.Because the base table is big i don't want to refresh the dataset (at least i don't want to have the user wait for a good amount of time for a simple change.......this is acceptable only when the application is starting) and i thought given the fact that the changed data are just a few words to "edit" the datagridview cell i want so that it displays the changes.BUT i can't do that.As soon as the 2nd form where the user enters the details the DGV from the main form is unaccessible.When i try to get access to it i have a nice message "Reference to a non-shared member requires an object reference."I tried to make a object reference but nothing ...
I want to set Color to specific cell in DataGridView as in this code , but didn't accept BackColor property. Form1.DataGridView1.CurrentRow.Cells(3)......BackColor
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 need to display a list with 2 columns and "n" rows (first column will be an IP address and second column the status - say connected, failed, etc).The case is that I need to be able to SET and GET the value of a certain cell. For instances, if the user click the first row of the list (row 0), I want to be able to get what is the intersection 0,0 (IP of first row) and intersection 1,0 (status of first row) and so on.I am trying Listview and Datagridview with no success.
I am filling a DataGridView from a table in SQL Server 2008. There is one column that is a string which contains either "YES" or "NO".When I run and display the DataGridView it displays perfectly. For the User's benefiy, if the field contains "NO" I want to put some emphasis on it by changing the fore color and back coler of the entire row. In the DGV the index for field is (4).I tried this code which threw an error on the word "value" inthe block that fills the DGV.
I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like
cell.value = string.substring(0,(whatever number I need it to be)).
how could I get the text of a specific cell in a DataGridView control ? If it matters , in my case , all the cells contain strings or nothing . For example , in order to get the text from the cell on row 2 and column 3 , what code do I have to use ? I have tried the Value property but seems that's not it . I've found some examples on the web ,but they were all for C# ... I guess , though , it has to be easy .
As I have no idea on how to retrieve access data at the specific location in the table, so I wrote VBA code t export the entire access database to a datagridview which is located in the form1. There's a column of datagridview contain complete address information of a image. I'm thinking a way to link image source (of form 2 or xaml file) to the the column so that the image will be displayed. is there any code to get cell value at the specific location in the table? In excel VBA, sheets("Sheetname").Cells(rownumber, columnnumber).value is used to get the cell value, but how about code for this case?
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 =
Within my PropertyGrid I have decorated a class with the following attributes:
Code: [Category("Category 1"), DisplayName("Part Number"), SortOrderAttribute(1)] Dim PN1 as String
[Code]...
The problem is that when PN2 is changed in the PropertyGrid, it causes a refresh of all cells. Since both properties have the same DisplayName, but different Categories, the focus is set to PN1 and not PN2 after PN2 is edited.
I have two datagrids in my form. I want to set focus to the particular cell of that datagrid. Result of one datagrid is to be displayed in the other one.
Have this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.
[code]...
I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.
