I have a program that gets some information from the user and updates the database.I also have two DataGridView, OpenOrders and ItemsInOrder When the user click on a cell in the OpenOrders a CellChange event is triggered and it updates the ItemsInOrder grid view. Now after I update the quantity of a product i want to cause that CellChange event to trigger again in order to refresh the ItemsInOrder grid view.
View 7 RepliesUsing VB.Net. I want to get a all datagrid cell values, then insert into table1.
Code
cmd = New SqlCommand("insert into table1 values('" & DataGrid.Rows(0).Cells(0).Value & "', '" & DataGrid.Rows(0).Cells(1).Value & "', '" & DataGrid.Rows(0).Cells(2).Value & "', '" & DataGrid.Rows(0).Cells(3).Value & "')", con)

The above code is inserting first row of datagrid cell value, but I want to insert all the datagrid cell values. How to modify my code for getting all the datagrid cell value.
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 have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

I am developing a software using datagridview (vb6 feels better) and i am using virtualMode.it shows the focus blue box but it is not possible to fill data to the first cell programatically.also i have used from within a button_click event as follows
1- MyGrid.CurrentCell.Value = 22
2- MyGrid.Rows(0).Cells(0).value = 22
3- MyGrid.BeginEdit(True)
3- MyGrid.CurrentCell.Value = strData
I tried alot of things to achieve this but sadly no positive result.How can I set a cell to edit.[code]The focus is on the right column and the right row (DataGridViewComboBoxColumn). But it is not in edit mode (the symbol in the the rowheader is an arrow (select) and not the pen (edit)).When I tab to a textcell I can just type the values. But on the DataGridViewComboBoxColumn I have to press F2 so its in editmode.
View 4 RepliesI programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.
When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.
Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?

I have a picturebox inside a panel, the picturebox is long, and the panel is set to allow scrollbars, which it adds. I can scroll the picture at design and runtime, but how do you scroll it programmatically?

So how do i get the value to change (e.g. to scroll the picturebox!)
i've come across many methods online to create a datetime picker within a datagrid view, but i haven't got a proper solution. i have a DGV which takes in truck no and date of arrival. i want the second column to appear as a datetime picker so the users can be restricted from entering anything else.

I am not sure if this should be in the SQL or vb.net section.But, Basically I have a vb.net application from where I insert a datetime field into the SQL Server Database. Now for some reason the SQL server field(which is datetime) will not display AM/PM, I have referred this link where my code looks like this:
Dim dateToDisplay As DateTime = DateTime.Now dsNewRow.Item("date_created") = dateToDisplay.ToString("MM.dd.yyyy hh:mm:ss tt")
I tried stepping into the code by debugging and it seems to be inserting the PM but is not displayed in the table QuotedateToDisplay#8/12/2011 6:01:06 PM#Date
inserting date/time to database manually using sql query.

I'm trying to dynamically add results to this display and I simply want to put a break tag after a label to start putting information on the next line. For some reason, Using a literal isn't working for me. Is there a better way to do this or should I just use tables?
Dim break As LiteralControl
break = New LiteralControl("<br />")
divListenerInfo.Controls.Add(break)
That's part of the code that I'm attempting to use.
Let me clarify what I said:
It's not working as in the line break isn't showing up on the webpage. It's compiling fine and there is nothing wrong with the code. It just doesn't show up in the html for some odd reason.

View 2 RepliesI would like to be able to programmatically create DataGridTemplateColumns based on my data source. For example, if my source has a date in a particular column I would like to be able to utilize a Datepicker control. I know this is easily accomplished with xaml and a DataGridTemplateColumn at design-time, however, how would I accomplish this at run-time?
Is my best option xamlreader.load or a more traditional route like:
Dim TempCol As Microsoft.Windows.Controls.DataGridTemplateColumn
I have not had any success with the latter.
