Web Combo Value in Web Grid Cell
posted

Hi folks,

I have a WebGrid set up with a WebCombo as a cell editor so that a user can select a value from the drop down to populate the cell value. I have type ahead set up on the WC and it has been working well.

If you try and type a value that is not in the drop down list, when you click out of the cell it simply blanks the value. Is it possible to modify the WG/WC behaviour to allow a value to be selected from the drop down and also allow a user to type in a value.

I realise what i'm askin kind of goes against having the drop down in the first place but if this can be done it would be very helpful.

I appreciate any help.

Thanks.
Jonny

    I am trying to use a combo box on a WebGrid so that I can have the benefit of adding new values to existing items.

    I am using a free ComboBox control for ASP.NET from MetaBuilders http://www.metabuilders.com/ and I can successfully populate a ComboBox outside of a webgrid.  How can I use a combo box on a column of the webgrid?

    This is what I have attempted so far (following the way to add a WebMaskedEdit control) but failed to work.

    1)  Declared a instance of the ComboBox

    Protected WithEvents cboHomeOfRecord As New MetaBuilders.WebControls.ComboBox

     2) In the IntializeLayout event, added the ComboBox to the Web Form:

    If Not pForm1 Is Nothing Then

     With cboHomeOfRecord

     .Enabled = True

     .Visible = True

     .ID = "cboHomeOfRecord"

     End With

     pForm1.Controls.Add(cboHomeOfRecord)

    End If

     3) In the IntializeLayout event, added the ComboBox to the Web Form:

     cboHomeOfRecord.DataSource =  (some function that returns an arryalist of objects)

    cboHomeOfRecord.DataMember =(Some field name )

    Note: a combo box control outside of a webgrid has been successfully populated by the same code as above, so I know the data source is correct

    4)  In IntializeLayout event, tied the ComboBox to a column of the Grid:

    ugrdMain.Bands(0) .FromKey("HomeOfRecord")

    .HeaderText = "Home of Record"

    .Type = ColumnType.Custom

    .EditorControlID = "cboHomeOfRecord"

    .Width =     New Unit(150)

     

    Any advice is much appreciated.
