Hi,
We are trying to use two versions of Telerik (2008 Q2 and 2009 Q1) on the same machine within the same application. Some of our modules use the older versions and a few use the newer one. We are having issues using this mixed mode.
Can you suggest us a way to get around this problem?
Is this documented anywhere?

Thanks and Regards
-Advait

[Solved] Get each contents of text portion of combo on each keystroke?

I would like a server side event (Ajax) handler be called on each key stroke in text portion of combo. Was wondering how to set up the control to do that? I know that that the behavior of TextChanged is only on form submit, but was looking for an Ajax type event.

Thanks in advance

Hierarchical RadGrid with Auto-Generated Columns: Converting Column Type

Hey Telerik pros,

Could use your help on this one...

I'm trying to use a nested RadGrid to show a BOM (bill of materials) i.e. parts are composed of simpler parts, which may in turn be composed of even simpler parts, etc.

I have a grid like so, using HierarchyLodeMode="ServerBind", and Unique_Id and Parent_Id to create a self-referencing hierarchy.

<telerik:RadGrid ID="RadGrid1" runat="server"OnNeedDataSource="RadGrid1_NeedDataSource" OnPreRender="RadGrid1_PreRender"AllowSorting="True">
    <MasterTableView HierarchyLoadMode="ServerBind" AllowSorting="true" DataKeyNames="Unique_Id, Parent_Id">
        <SelfHierarchySettings ParentKeyName="Parent_Id" KeyName="Unique_Id" />
    </MasterTableView>
    <ClientSettings AllowExpandCollapse="true">
        <Selecting AllowRowSelect="True"></Selecting>
    </ClientSettings>
</telerik:RadGrid>

Then, in the code-behind, using OnNeedDataSource event:

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSource = GetDataTable(); //fetches data, returns DataTable

}

And in the PreRender, hiding the expand column for those rows that don't have anything nested beneath them:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

HideOrShowExpandColumnRecursive(RadGrid1.MasterTableView);

}

protected void HideOrShowExpandColumnRecursive(GridTableView tableView)

{

GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);

foreach (GridNestedViewItem nestedViewItem in nestedViewItems)

{

foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)

{

if (nestedView.Items.Count == 0)

{

TableCell cell = nestedView.ParentItem["ExpandColumn"];

cell.Controls[0].Visible = false;

nestedViewItem.Visible = false;

}

if (nestedView.HasDetailTables)

{

HideOrShowExpandColumnRecursive(nestedView);

}

And all that works great, I can get the self-referencing hierarchical grid of X levels (where X isn't known until you get the data).

Now, my problem is trying to convert the type of these auto-generated columns, from the regular GridBoundColumn to something like GridHyperLinkColumn. I can't figure out how to do that, maybe it's not possible?

As another approach, I tried adding a GridHyperLinkColumn to the nested views during the PreRender event, but I can't get that to work either.

Does anybody have any suggestions on how to either a) convert the type of these auto-generated columns or b) dynamically add another column to the grid? All I really want is to be able to add a hyperlink to each row in this type of nested grid.

Much thanks,
ET

RadMaskedTextBox formatting phone numbers incorrectly.

I am using the RadMaskedTextBox controls for several phone number entries on a web form. I used the Smart tag to set up the mask I wanted to use and used declaritive binding in the page markup, like this:

<telerik:RadMaskedTextBox ID="txtPhone" runat="server" Mask="(###)###-####" Text='<%# DataBinder.Eval( Container, "DataItem.Phone" ) %>'

TabIndex="6" EmptyMessage="-- Enter Phone Number --" HideOnBlur="true" ZeroPadNumericRanges="true" DisplayMask="(###)###-####">

</telerik:RadMaskedTextBox>

However, when the value from the data store is bound to the control, the output is displaying incorrectly. For instance, if the phone number in the data store is, "1112223333", then I would expect the masked display to appear as, "(111) 222-3333", but what is shown instead is, "(111) ___-222_".

Has anyone else seen this or found a work-around?

Thanks in advance,

Jon

Google spellcheck service

Wasnt this implemented recently? I even had information on how to put it in -

Create a GoogleSpellCheckProvider class that implements the ISpellCheckProvider.

Set SpellCheckProviderTypeName property of RadSpell to = typeof(Telerik.Web.UI.GoogleSpellCheckProvider).AssemblyQualifiedName of compiled GoogleSpellCheckProvider created.

This still works?

Thanks.

Changeing RadGrid Datasource At Runtime Edit Problems

I have a form with a grid and a combo box where a user can select the table name they wish to edit. I have the grid binding to the table name selected by calling Rebind() when the user makes a table name selection, and by handling the NeedDataSource event of the grid to bind to a DataTable. That seems to work fine.

The problem comes in when I try to edit. I added a GridEditCommandColumn to the MasterTableView's Columns collection so I get a link to start editing a row, and the editor form appears just fine. But when I click on 'update', and I try to handle the UpdateCommand event raised by the grid (from code cobbled together from forums), I get an argument out of range exception, that I believe is coming from the edited item's OwnerTableView.DataKeyValues collection which has zero elements.

One other thing to note, I am using Postgres as the database, but I don't think this is the issue, as I am using npgsql to get standard ado.net objects to bind to.

Any ideas?

Private Sub RadGrid1_UpdateCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.UpdateCommand

Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim table As DataTable = Me.GridSource

'Locate the changed row in the datasource

Dim pk As String = GetPrimaryTablePKColumn(cboTable.Text)

If pk Is Nothing OrElse pk.Trim = String.Empty Then

e.Canceled = True

Return

End If

'Error Happens Here

Dim changedRows As DataRow() = table.Select(pk & " = " &

editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)(pk).ToString)

If changedRows.Length <> 1 Then

e.Canceled = True

Return

End If

'Update new values

Dim newValues As New Hashtable

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem)

changedRows(0).BeginEdit()

Try

For Each entry As DictionaryEntry In newValues

changedRows(0)(DirectCast(entry.Key, String)) = entry.Value

Next

changedRows(0).EndEdit()

Catch ex As Exception

changedRows(0).CancelEdit()

e.Canceled = True

End Try
