I am creating a windows application for my company. in the master file i will enter the number of items we are getting from the customer. and in the next page i have to enter the details of each item. For that i have created a datagrid which has one autogenerate number field and the remaining fields must be editable. So that when i enter all the values in the datagrid, it has to go and save in the data base.

In Page1 RMNNo will be generated automatically and it will ask the user to enter the number of items in Page2. So in next form, all the item details i want to enter. But i cant display the second screen multiple times, I decided to create a table at run time, the number of rows will change depending on the number of items entered by the user. But in the table we may have to get some of the values from the database and display as a combo box so that the user can select from the list. So i decided to use the editable data grid.
we display a decimal(11.25) value in the grid . When we try to edit that cell its displaying only (11).Its not showing the decimal value when we try to edit that cell.
How to format that cell ?
I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:
1. When editing a cell, it adds a new row: [url] How can I prevent this?
2. I don't like the grey background and would like the grid to fill the whole space, right and below.
BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]
I have a datagridview with 5 columns on it. It has two "views" according to whether the user is logged in or not. If they aren't logged in all 5 columns are readonly. If they are logged in 2 of those columns become usable but the other 3 are still readonly.
My issue is "how do I allow someone to add a row to the grid without turning off my readonly columns"?
I know that I could change the readonly status for the columns and then change it back after I add the row...but I was hoping for something easier. Or at least only to unlock the "new" row area, but leave the rest alone.
Is it possible to set readonly on dgv cells as well? Or just on the columns and grid object?

But this makes every cell in column editable. Is there a way i can make some cells editable in column? If you know how to do it,

View 2 RepliesThis is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

View 5 RepliesI have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?

View 1 RepliesData binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
