i dont have vs.net on this machine to try it out, but have you noticed that all of the properties that have the sub properties, are objects that have properties, e.g. Size has the properties Width and Height in it. Try grouping the properties that you want grouped in the designer into a seperate object, and use that as a property, and it may do the trick, but i dont know.

Thanks Nnamdi. You're correct that these properties need to be grouped into a separate class. But that alone does not do it. Check out the solution[^]. It's amazingly simple. Smile | :)

Hi anyone have a short code snippet of adding a sub item in the detail view, i direly need this

and the below doesnt work

listView1.View = View.Details;
// Allow the user to edit item text.
listView1.LabelEdit = true;
// Allow the user to rearrange columns.
listView1.AllowColumnReorder = true;
// Display check boxes.
listView1.CheckBoxes = true;
// Select the item and subitems when selection is made.
listView1.FullRowSelect = true;
// Display grid lines.
listView1.GridLines = true;
// Sort the items in the list in ascending order.
listView1.Sorting = SortOrder.Ascending;

// Create three items and three sets of subitems for each item.
ListViewItem item1 = new ListViewItem("item1",0);
// Place a check mark next to the item.
item1.Checked = true;
item1.SubItems.Add("1");
item1.SubItems.Add("2");
item1.SubItems.Add("3");
ListViewItem item2 = new ListViewItem("item2",1);
item2.SubItems.Add("4");
item2.SubItems.Add("5");
item2.SubItems.Add("6");
ListViewItem item3 = new ListViewItem("item3",0);
// Place a check mark next to the item.
item3.Checked = true;
item3.SubItems.Add("7");
item3.SubItems.Add("8");
item3.SubItems.Add("9");

// Create columns for the items and subitems.
listView1.Columns.Add("Item Column", 100, HorizontalAlignment.Left);
listView1.Columns.Add("Column 2", 100, HorizontalAlignment.Left);
listView1.Columns.Add("Column 3", 100, HorizontalAlignment.Left);
listView1.Columns.Add("Column 4", 100, HorizontalAlignment.Center);

//Add the items to the ListView.
listView1.Items.AddRange(new ListViewItem[]{item1,item2,item3});

Well actually the code worked, i had this odd idea there would be additional lines created but no i was wrong. I guess I mus use a tree view which I did not want to do.

datagrid column widths

i've seen lots of links to the syncrofusion site, but it still doesn't clear up the column width problem.

i've added a tablestyle to my datagrid, .. and then i've added grid column styles to my table style.

i populate my datagrid like this:

<br />
dataGrid1.SetDataBinding(ds,"Contacts");<br />

but how do i bind the tablestyle / column styles to this datagrid?

i thought that is what i was doing in the gui of VS, but it does not pick up the widths i set.

can someone clear this up any?

Ista12-Aug-03 11:56

Re: datagrid column widths

12-Aug-03 11:56

myDataGrid.DataSource = myTable;

do a clear on the tables styles object before adding it, its easier.

you have to set the Mapping Name of the tablestyle to that of the database table you want this style to apply to.. For exampe "Mapping Name = Contacts".. Also apply the mapping name of each columnstyle to map to the corresping column of your database table..

the .NET framework doesnt have this ability, so you will have to use MSDN to find the API's used to get/set the variables, then import the functions.

As a follow up to Nnamdi's comment, you can use the API SetEnvironmentVariable, but that only places the variable in the process's local environment. If you want the change to be system-wide (permanent), you need to modify the registry.

Take a look at these two keys in your registry:

System variables: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
User variables:   HKEY_CURRENT_USER\Environment

No clue, but my first guess would be portability. My second guess would be to encourage you to pursue a better mechanism, such as files.

I want to be able to trigger a button on the form from within the DataGrid with the Enter Button.

The variables are already in the proper places upon any change in the cell, .. so I just need to be able to capture Enter, and have it trigger a button.
