View 2 RepliesWhen 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 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'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. The user can add a new record so i can't set the two bound column to read only. Is there anyway i can do this in the ASPX or do i have to do it in the code behind? I have some code that is working but it is not the best.Here's my code:
Case "Edit"
Dim aoeAnswerCode As GridBoundColumn = CType(e.Item.OwnerTableView.GetColumn("aoeAnswerCode"), GridBoundColumn)
aoeAnswerCode.ReadOnly = True
Case "Update", "PerformInsert"[code].....
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]

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.

View 4 Repliesso I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form
[Code]...
I have an application that saves details to then be viewed in a datagridview on another form. Clicking on an entry in the datagrid (I want to make this double-click, but haven't bothered to try yet) highlights the row, and loads the values to a new form, in read-only text boxes. Clicking Edit changes the read-only value of these text boxes and allows you to edit (obviously) the contents. I have another button, Save which I want to click to commit the changes to the loaded items in the datagrid.
