Inserting into Details Table and grab ID from Parent Table ID

Hi,

I have a main grid with two hierarchical levels, the main level, and the child level. I am trying to insert record on the main level, and then once I have that record inserted, be able to insert a record onto the child record of that record, but insert it using the same ID as the main record. I already looked at this demo, http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/threelevel/defaultvb.aspx,
and it is from where I am getting my bases from, but I am having difficulty when trying to insert a record onto the child level. I am using DatabaseAccessors not SQL connection strings or SQL Commands, I am working in vb.net. I am not sure how to save the fields being inputted, or if there is a way to treat the insert commands for the child table the same as the main table.

[Solved] GridCalculated Column inside a Template Column

I have a requirement where I need to have a GridCalculated column inside a GridTemplateColumn. I tried to search online but could not an answer to it.
when I try to add it I get an error.
Is it possible to have a GridCalculatedColumn inside a GridTemplateColumn? If yes then I would need a way to update it client side if a User changes a value.

Server-side (Dynamic) Creation of Treeview inside Combobox inside Toolbar

Consider:

I am dynamically creating a toolbar that has a RadComboBox button, such that I do the following:

' in the page_load:

If Not m_ThisPage.IsPostBack Then

Dim btnSearchByTxt As New RadToolBarButton()

btnSearchByTxt.Text = "SearchFor"

btnSearchByTxt.Value = "searchfor"

m_RadToolBar.Items.Add(btnSearchByTxt)

InstantiateSearch()

Dim cboSearchItem As RadToolBarItem = m_RadToolBar.FindItemByText("SearchFor")

Dim cboSearchBox As RadComboBox = CType(cboSearchItem.FindControl("SearchComboBox"), RadComboBox)

AddHandler cboSearchBox.SelectedIndexChanged, AddressOf cboSearchBox_SelectedIndexChanged

End If

' -------------- snip ----------------

Private Sub InstantiateSearch()

Dim searchTemplate As New ComboBoxSearchTemplate

Dim cboSearchItem As RadToolBarItem = m_RadToolBar.FindItemByText("SearchFor")

'Dim searchTemplate2 As New TextBoxSearchTemplate()

'Dim textSearchItem As RadToolBarItem = m_RadToolBar.FindItemByText("SearchFor")

If TypeOf cboSearchItem Is RadToolBarButton Then

searchTemplate.InstantiateIn(cboSearchItem)

End If

m_RadToolBar.DataBind()

End Sub

Private Class ComboBoxSearchTemplate

Implements ITemplate

Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

Dim cboBox1 As New RadComboBox()

cboBox1.ID = "SearchComboBox"

cboBox1.DropDownWidth = 460

cboBox1.Sort = RadComboBoxSort.Ascending

cboBox1.SortCaseSensitive = False

'cboBox1.DropDownCssClass = "searchDropDown"

cboBox1.AllowCustomText = True

cboBox1.AutoPostBack = True

cboBox1.EmptyMessage = "Search for..."

cboBox1.EnableItemCaching = True

cboBox1.EnableLoadOnDemand = True

cboBox1.MaxHeight = 320

cboBox1.MaxLength = 2999

cboBox1.Width = 250

cboBox1.ExpandDelay = 2500

cboBox1.LoadingMessage = "Searching..."

cboBox1.Attributes.Add("onitemsrequested", "SearchComboBox_ItemsRequested")

'cboBox1.Attributes.Add("onkeydown", "fire()")

cboBox1.OnClientKeyPressing = "fire"

cboBox1.CloseDropDownOnBlur = False

cboBox1.Text = ""

cboBox1.Font.Size = 9

cboBox1.Font.Bold = False

cboBox1.Font.Name = "Sans-Serif"

cboBox1.DataTextField = "CMM_DESCRIPTION"

cboBox1.Items.Add(New RadComboBoxItem(""))

Dim ctt As ComboBoxTreeTemplate = New ComboBoxTreeTemplate

ctt.InstantiateIn(cboBox1.Items(0))

AddHandler cboBox1.DataBinding, AddressOf cboBox1_DataBinding

AddHandler cboBox1.ItemsRequested, AddressOf cboBox1_ItemsRequested

cboBox1.DataBind()

container.Controls.Add(cboBox1)

End Sub

End Class

Private Class ComboBoxTreeTemplate

Implements ITemplate

Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

Dim rtv As RadTreeView = New RadTreeView()

rtv.ID = "RadTreeView1"

rtv.Skin = "Telerik"

rtv.SingleExpandPath = True

rtv.DataTextField = "CMM_DESCRIPTION"

rtv.DataValueField = "CMM_ID"

rtv.DataFieldParentID = "CMM_PARENT_ID"

Dim sProc As String = "sptMaterialInventory_AddEdit_GetCommodity"

Dim connection As New SqlConnection(ConfigurationManager.ConnectionStrings("TRACURATEConnectionString").ConnectionString)

Dim adapter As New SqlDataAdapter(sProc, connection)

adapter.SelectCommand.CommandType = CommandType.StoredProcedure

Dim dataTable As New DataTable()

adapter.Fill(dataTable)

rtv.DataSource = dataTable

rtv.DataBind()

container.Controls.Add(rtv)

End Sub

End Class

The idea is that I want to populate the combobox in the toolbar, with a treeview. First, for some reason, the treeview is flat. If I use the same stored procedure in a treeview that I create in ASPX, it renders perfectly. Using the exact same in this dynamic fashion, there are no parents/children. Just a flat list of all nodes.

Second: the treeview is fine the first rendering of the page. When an AJAX post-back occurs, I get an error stating that the treeview does not exist.

I am looking for two answers:

1) How do I get the full treeview with parent/children to render?
2) How do I cause the treeview to not disappear after the first AJAX post-back?

I hope that this is enough code for you to understand what I am doing.

Thank you,

Tomas

Double clicking not distinguishing with single clicking

We have inherited a project that uses RADGrid. It has both events for double and single clicking enabled.

I saw this forum post:
http://www.telerik.com/community/forums/aspnet-ajax/grid/rowclick-amp-rowdoubleclick.aspx
Reading through your documentation, EnablePostBackOnRowClick should be set to false by default, but I tried setting it explictly and I am still experiencing the problem. I put breakpoints in Javascript on the rowclick and rowdblclick events, and rowdblclick never fires; rowclick fires twice.

I did notice that your Silverlight controls have a mouse speed, and that your scheduler product has something that needs to be reset that keeps track of state. Is there anything comparable in the Grid? Any other tips or gotchas to making this work correctly?

Thanks,
Rebecca

Set default values for Upload in base class

I have a few web forms that proccess excel files, so in order to make this easier, I have a base class like this:

public abstract class ExcelImporter : Page {
    public abstract RadAsyncUpload FileUpload { get; }

    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        if (FileUpload != null)
        {
            DefineRadAyncUpload();
        }
    }

    private void DefinirRadAyncUpload()
    {
        FileUpload.Skin = Skin;
        FileUpload.Culture = new System.Globalization.CultureInfo("pt-BR");
        FileUpload.TemporaryFolder = "~/temp";
        FileUpload.OnClientFileUploaded = "PostBackAsyncUploadComplete";
        FileUpload.AllowedFileExtensions = new[] { "xls", "xlsx" };
        FileUpload.MaxFileInputsCount = 1;
        FileUpload.FileUploaded += FileUploadOnFileUploaded;
    }

    protected abstract void FileUploadOnFileUploaded(object sender, FileUploadedEventArgs fileUploadedEventArgs);
}

Everything i'm setting in the Define method is working, except the extension filter. What am I doing wrong? is there another moment that I shoud set this property?

Persist CurrentFilterValue and CurrentFilterFunction

I'm using the Profile and the grid persistence code located here:
http://www.telerik.com/community/code-library/aspnet-ajax/grid/storing-multiple-grid-settings-in-database-via-profile.aspx

This code lacks the ability to save CurrentFilterFunction and CurrentFilterValue.

I've tried the new code persistence, but can't get it to save with the profile code and really don't want to redo everything. Any help on saving & loading just CurrentFilterFunction and CurrentFilterValue with the original code?

Weird Grid Display Issue

I seem to have stumbled across a weird display issue with the grid control. On odd page number, the row spacing/column size is appropriate. However, on even pages, the columns seem to have shrunk and thus seem to have double-spaced each row. See attached screen shots.
