Editing Listview Subitem

Hi

I am working on vb.net
I can edit a listview item by setting the labeledit property to true.
Can you please tell me how can I edit the listview subitems? User should just click on the subitem and start editing.
Also, without using any other control ,is it possible to add more items to listview at runtime, like we can add rows in excel sheet.

Pls help me out.

Have a nice day

add items to listview at untime is quite simple:

        Dim myListvItem As ListViewItem

        myListvItem = myListView.Items.Add("some text")
        myListvItem.SubItems.Add("subitem text")
        myListvItem.SubItems.Add("subitem text")
        myListvItem.SubItems.Add("subitem text")
        ....

myListvItem is necessary to make a reference to new listview item added

for the first stuff, maybe you can make a new control that inherits listview and implement with your own code the subitems editing.

I am not looking for adding subitems through code. The user should just click on the new row in the listview and start writing the text. This is what I am looking for.

Can you please tell me which methods I need to edit or modify ,if I inherit the listview control.

ok lj, now i understand.
so why don't you use a datagrid control? it seems to be the thing you wanna get!
or simply, why don'you add a button at the top of the listview, set text to "Add" and when the user click that button shows a form with a textbox and a label for each column of the listview?
i think it's more user friendly, and a good workaround.

I tried using the data grid control,but for no use.
Can you tell me how to use it and also will the users be able to add rows to the datagrid?

I work around suggested by you is a good one, but the requirement of the project is that, the users should be able to edit in the same screen.

waiting for your response

in order to use datagrid, you must bind a datasource to it. here is it a working sample. look at this and costumize it for fitting your needs:

        Dim dr As DataRow

        ds.Tables.Add("MyTables")

        ds.Tables(0).Columns.Add("Type", System.Type.GetType("System.String"))
        ds.Tables(0).Columns.Add("Qty", System.Type.GetType("System.Int32"))

        dr = ds.Tables(0).NewRow
        dr.Item("Type") = "myProduct1"
        dr.Item("Qty") = 50
        ds.Tables(0).Rows.Add(dr)

        dr = ds.Tables(0).NewRow
        dr.Item("Type") = "myProduct12"
        dr.Item("Qty") = 150
        ds.Tables(0).Rows.Add(dr)

        dr = ds.Tables(0).NewRow
        dr.Item("Type") = "myProduct3"
        dr.Item("Qty") = 500
        ds.Tables(0).Rows.Add(dr)

        With DataGrid1
            .DataSource = ds.Tables(0).DefaultView                     '**** this set the datasource
            .RowHeadersVisible = False                                       '**** this hides the row header
            .CaptionText = "My Caption Text"
            .CaptionVisible = True
            .ReadOnly = False                               '**** IMPORTANT it must be false otherwise you'll cannot add new rows
            .AlternatingBackColor = Color.AliceBlue
        End With


that's all.
if you already got a dataset which contains the value you actually display in the listview, forget the first part of the sample and consider only the block With...End With

bye

It must be set to report!!!

 ' Set the view to show details.
        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

the edge,

I have no table to retrieve data from. I have an array from which i need to fetch the data into the data grid. Also, can I edit the fields in the datagrid.

you can also bind ArrayList to datagrid trough the datasource property.
see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformsdatagridtablestyleclassmappingnametopic.asp
to learn how to do this.

you can also copy your data for the array to a new dataset, bind the dataset to the datgrid, and then, when it needs, copy the changed data from dataset back to the array.
