ShowAddNewRecordButton in DetailTables

[Martin]

I have several RadGrids which I'm modifying programatically so that....
 
If the user clicks "Edit", ShowAddNewRecordButton is set to 'False' and I rebind the grid.
If the user clicks "Add New Record", e.Item.Edit is set to 'False' and I rebind the grid.

In effect, this means that the user cannot access the 'edit' and 'add new' forms at the same time.  Only one can ever be open.  I do this for a couple of reasons. 

Firstly, if the user tries to add a record AND edit a record (both the 'add new' and 'edit' forms are open simultaneously), if the user tries to submit the edited record first, the validation on the 'add new record' form fires - preventing the edit from occuring. 

Secondly, I have controls which I want to appear when the user adds a new record, but I want hidden when they edit a record.  I've been able to program the grid to hide the controls If the user edits a record, BUT if the user edits a record THEN clicks the 'adds new' button (whilst the edit form is still expanded), the controls show in both the add new AND - unfortunately - the edit forms.

By controlling access to the "Edit" and "Add New" forms so only one can be open at any one time, this resolves the above issues.  Unfortunately, I have a DetailTable which I'm also trying to program to behave the same way but I don't know how to reference the ShowAddNewRecordButton value when it's within a DetailTable.  Also, when I rebind the grid, it loses the expanded row (which you'd expect).  Any ideas?  My code is below...

Protected Sub rdgRiskType_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rdgRiskType.ItemCommand

    'If user inserts a new Risk Type record, set 'edit' mode to false and rebind (all 'edit' forms will be minimised).
    If e.CommandSource.Text = "Add New Risk Type" Then
        e.Item.Edit = False
        rdgRiskType.Rebind()
    End If

    'If user edits a Risk Type record, hide the 'Add New xxx' button (user can't then add a new record whilst an edit form is maximised).
    If e.CommandSource.Text = "Edit" Then
        rdgRiskType.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = False
        rdgRiskType.MasterTableView.IsItemInserted = False
        rdgRiskType.Rebind()
    End If

    'If user inserts a new Risk record, set 'edit' mode to false and rebind (all 'edit' forms will be minimised).
    If e.CommandSource.Text = "Add New Risk" Then

    End If

    'If user edits a Risk record, hide the 'Add New xxx' button (user can't then add a new record whilst an edit form is maximised).
    If e.CommandSource.Text = "Edit Risk" Then

    End If

End Sub

Hi Martin,

You could clear all opened items for edit by calling either rdgRiskType.MasterTableView.ClearEditItems() or rdgRiskType.EditIndexes.Clear(). Additionally, you could clear them on a GridTableView level by calling e.Item.OwnerTableView.ClearEditItems(). 

Accessing the ShowAddNewRecordButton requires only the index of the DetailTable and can be done by calling rdgRiskType.MasterTableView.DetailTables[detailTableIndex].CommandItemSettings.ShowAddNewRecordButton = false. You could also try not calling the Rebind() method and see if the application continues running as expected.
