i've made form with DGV... when user selects or enters a cell and presses F1 a help form pops up.... but when the cell is in edit mode and presses F1 .... nothing is happening ... is there any way to handle keydown in cell while is in edit mode ..
View 1 Repliesin VB.NET DGVedit mode, after press ENTER to move the active cell into the desired cell, notdirectly move to the next line, how is it?
View 2 RepliesI have a DataGridView in which one column has data that the user needs to align by adding spaces. For example, the first two rows might contain:
kumbu
kuimbiu
And the user needs to be able to line up the letters that match by adding spaces. Something like this:
ku mb u
kuimbiu
Now in order to do that with the DataGridView, the user must enter edit mode in the top cell, add spaces, hit enter, re-enter edit mode in the bottom cell, and then add spaces. Our users would like to be able to, while in edit mode in the top cell, hit the down arrow and advance to the second cell while staying in edit mode, saving clicks or F2 hits.
Is there a good way to do this? I have tried trapping the down arrow key press, leaving edit mode, advancing a cell, and then entering edit mode with the grid's BeginEdit method, but this does not do what I want.
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.
Ok here's my dilemma. here's this code I have:
If e.KeyCode = Keys.A Then
TextBox1.AppendText("C, ")
PictureBox2.Visible = True

I'm using a Datagridview my task is when the key F5 press using Keydown event executing some code
View 1 RepliesI don't have an example code, but recently figured out how to make a single sub handle the keydown event for multiple text boxes.What I would like to know is if it is simple enough to have the object name that is sending the event instead of "microsoft..text: 54654" (sender.ToString in a debug window) type of return. I don't know how to make use of that.

View 1 RepliesI'm using an on key down event for my datagridviewer that fires every time a key is pressed while the datagridviewer is selected(Focused).I want the same thing to happen while in a cell, but there is no event for key down in a cell.
View 3 Repliesi have a datagridview with a readonly cell, i would like to show a formdialog window when the user press the space key. but is not possible since the cell is readonly=true.
i'v been using the following code with the EditingControlShowing event. and when the cell is readonly=false it works sometimes.
Private Sub sub_fecha_keydown(ByVal sender As Object, ByVal e As KeyEventArgs)
If e.KeyCode = Keys.Space Then
Dim frm As New frmFecha

how to handle the keypress event but I can't find a way to update the datagridview cell with the new contents of the editing textbox control. If I add a character to a the text of a cell I want it to react with the new cell contents.

When in "Add" mode, I have all controls on the form enabled with the exception of a listview that is disabled until the record is saved. The listview needs the primary key from the saved record in order for items to be added to the listview.
When in "Edit" mode, the form is populated when a record is selected on a search form. Specific controls are disabled. When a value in a control is changed, I have a RecordModified property that is set to True and then the Save button is enabled. I also have combo boxes that need to be populated but the selected value needs to correspond to the value pulled from the database
This should be something simple, but I just cant make it work. I have a DataGridView with a "Technician" column that I would like to have a dropdown box, allowing the user to select and assign that row to X technician. It works, however with the default edit mode, you have to click the box THREE times to get the dropdown. If the edit mode is changed to "Edit On Enter", it works FIRST click, but this ruins the way I want some of my other columns to work.
Questions:
1. Can I enable/disable editing of ONLY certain columns?
2. Can I set the edit mode for ONE column?
3. My "Unassigned" section (the last line) no longer works after adding my "With" section to add my combobox. I thought the "DataPropertyName" would allow this to work. Whats the deal?
4. Can I edit the visual style of the combo box? It does not match AT ALL

When the cell is selected but not open for editing a right click will open the ContextMenu. If the cell is open in edit mode a differnt list is displayed (cut, copy, paste, etc.). Is there a way to append the ContextMenu to this menu or turn that menu off and use the ContextMenu?

View 1 RepliesI've been searching all over and unable to find a way to do this. I'm not sure if it is possible but thought I would ask. I have a program that runs in the background and hooks the keyboard keys to perform actions when a hotkey is pressed. However I don't want it to do anything if the forground window (of another application) is in edit mode so if you map the v key, the user will still be able to enter it in a text box. Is there a way to detect if the forground window or control is currently in edit mode?
View 2 RepliesBasically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.

View 1 RepliesI have a Telerik RadGrid that has three bound columns and one button column. I would like to let the user edit the values in only one of the bound columns.

I have an application that loads a web page then allows the user to edit that page by setting the Webbrowser control to EditMode.What I am trying, so far unsuccessfully, to do is trap when a user right clicks on a link already on the web page. The problem I have is that although I can trap the right click using MouseDown and GetElementFromPoint, if the link that is clicked is nested within a higher level element then the higher level element is returned by GetElementFromPoint not the nested element.[code]When the user right clicks, say, the link with test2.html my current code returns the DIV element not the A element. How can I understand which of the A elements the user clicked.[code]

View 8 RepliesI was thinking get the row index and then the cell index and using that to get the specific cell I need somehow but I do not know how to get the specific cell, so would this be easiest if so what command would I use to get the information from the cell, if not how would a better way to do this be?
I cannot find the way to get the row index if one exists so I am guessing it does not exist with this method so how would I go about getting the information from a specific column of a selected row?

I'm inheriting a couple of the common WinForms controls and then manually repainting them so that they will correctly render over a WinForm with the Aero Glass effect enabled. I have this working well with the TextBox. I ran into a snag with the ComboBox though in that it would only repaint some of the control. I fired up MS Spy++ and saw that the ComboBox has an Edit control in it (that's not in it's control collection). I can repaint that Edit box, but I need to get the handle of it and a couple of my attempts have flopped. I found some code that used the FindWindowEx API passing the Comboboxes handle but for me it returns 0.
hwndEdit = FindWindowEx(Combo1.hwnd, 0&, vbNullString, vbNullString)
Basically, I need the handle of the edit control inside the combobox (once I understand how to correct get that then I can get the additional controls in other ones I want like the ListView). Here's the Spy++ screen shots to illustrate (from Spy++ I can see the individual handles).
