I am using RabTabStrip.Net2.dll v3.6.6. I would like the tab to be bottom to top, why following code shows the same orientation as I use TopToBottom?

<

radts:radtabstrip id="tab" Orientation="HorizontalBottomToTop" Runat="server" AutoPostBack="True" SelectedIndex="0" Skin="WebBlue">

<Tabs>

<radts:Tab Text="Tab1" ID="Tab1" Width="100"></radts:Tab>

<radts:Tab Text="Tab2" ID="Tab2" Width="100"></radts:Tab>

<radts:Tab Text="Tab3" ID="Tab3" Width="100"></radts:Tab>

<radts:Tab Text="Tab4" ID="Tab4" Width="100"></radts:Tab>

</Tabs>

</

radts:radtabstrip>

ClientDataString method missing in newer version

Hi,
I've been trying out the telerik control and realized that the ClientDataString method is not available any more in the RadComboBoxItemsRequestedEventArgs class.

I am working on a migration project from old telerik control to newer one, I am using version 2011.2.712.35, what is the alternate method that I should use.

Cheers

ComboBox

NeedDataSource Format Columns

<telerik:RadGrid ID="RadGrid1" runat="server"

OnNeedDataSource="RadGrid1_NeedDataSource" Skin="Default">

<MasterTableView AutoGenerateColumns="true">

</MasterTableView>

</telerik:RadGrid>

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs)

Dim dt As DataTable

If Session("dt") Is Nothing Then

dt = New DataTable()

dt.Columns.Add("money")

For i As Integer = 1 To 10

dt.Rows.Add(i)

Next

Session("dt") = dt

Else

dt = TryCast(Session("dt"), DataTable)

End If

RadGrid1.DataSource = dt

End Sub

How do I format the money column to US currency or any of other formats available in radgrid? Thanks

RadGrid ItemDataBound: OwnerTableView.Items[0] - Out of range exception

I have a child grid on a page.

In it's declaration I have added a call to the event handler "OnItemDataBound".

OnItemDataBound="rgContacts_ItemDataBound"

Back in the code behind I have this..

protected void rgContacts_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem && e.Item.OwnerTableView.DataSourceID == "dsContacts")

{

Literal ltPrimaryContact = e.Item.FindControl("ltPrimaryContact") as Literal;

}

If there are 2 rows in the Contacts grid, then this method gets called twice as you would expect.

Furthermore, the IF condition is true in both cases.

However if I put a break point on the line within the IF condition, and in the watch window examine the value of...

e.Item.OwnerTableView.Items[e.Item.ItemIndex]

I get this error...

'e.Item.OwnerTableView.Items[e.Item.ItemIndex]' threw an exception of type 'System.ArgumentOutOfRangeException'    Telerik.Web.UI.GridDataItem {System.ArgumentOutOfRangeException}

Needless to say, if I try this...

e.Item.OwnerTableView.Items[e.Item.ItemIndex]["con_Phone"].Text

Where 'con_Phone' is one of the values from the grid, I get the same error.

I am unable to extract any of the values in the current row.

I am using the code on this Telerik page. Alas it does not work.

http://www.telerik.com/help/aspnet-ajax/grid-extract-primary-key-for-parent-item-in-hierarchy-on-update-insert.html

What am I missing here?

Thanks.

RadFilter, Radgrid, Custom filter with OnNeedDataSource and FilterContainerID

Hello,

I read a couple of articles and forum threads about applying a dropdownlist (combobox) as a filter option in RadFilter.

The samples uses a DataSource in the page though, while I want to use the OnNeedDataSource for the grid and the FilterContainerID for the RadFilter to automatically show filter field.

Here is what I got to far, so I don't get any errors:

<telerik:RadGrid ID="rgTasks" runat="server" OnNeedDataSource="rgTasks_OnNeedDataSource"

EnableViewState="false" AutoGenerateColumns="false" Skin="WebBlue" PageSize="10"

EnableLinqExpressions="true" AllowPaging="true" AllowSorting="true" AllowFilteringByColumn="true"

ShowStatusBar="true">

<PagerStyle AlwaysVisible="true" Position="Top" Width="100%" />

<MasterTableView DataKeyNames="OID" ClientDataKeyNames="OID" IsFilterItemExpanded="false">

<SortExpressions>

<telerik:GridSortExpression FieldName="Startdatum" SortOrder="Ascending" />

</SortExpressions>

<Columns>

<telerik:GridBoundColumn DataField="OID" HeaderText="OID" Visible="false" AllowFiltering="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Volgnummer" HeaderText="Volgnummer" Visible="false"

UniqueName="Volgnummer" AllowFiltering="true">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Taak" HeaderText="Dossier" DataType="System.String"

UniqueName="Taak" AllowFiltering="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Status" HeaderText="Status" DataType="System.String"

UniqueName="Status">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Startdatum" HeaderText="Startdatum" HeaderStyle-Width="110px"

DataFormatString="<nobr>{0:dd/MM/yyyy}</nobr>" UniqueName="Startdatum" AllowFiltering="true">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true">

<ClientEvents OnRowClick="rowClick" />

<Resizing AllowColumnResize="true" />

<Selecting AllowRowSelect="true" />

<DataBinding EnableCaching="true">

</DataBinding>

</ClientSettings>

</telerik:RadGrid>

<FieldEditors>

<custom:radfilterdropdowneditor datatextfield="Status" datavaluefield="Status" fieldname="Status"

datatype="System.String" displayname="Status" />

</FieldEditors>

</telerik:RadFilter>

Code behind:

protected void rgTasks_OnNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

DataTable dt = new DataTable();

dt.Columns.Add("OID", typeof(long));

dt.Columns.Add("Taak", typeof(string));

dt.Columns.Add("Startdatum", typeof(DateTime));

dt.Columns.Add("Status", typeof(string));

dt.Columns.Add("Volgnummer", typeof(int));

StoredProcedure sp = new StoredProcedure("getAllAanvragen");

sp.addParameter("@regOID", "7");

DataSet ds = sp.executeDataSet();

if (ds != null && ds.Tables.Count > 0)

{

foreach (DataRow row in ds.Tables[0].Rows)

{

DataRow newRow = dt.NewRow();

newRow["OID"] = long.Parse(row["OID"].ToString());

newRow["Taak"] = CommonFunctions.makeDossiernummer(row["Dossiernummer"].ToString(), row["Volgnummer"].ToString());

newRow["Volgnummer"] = int.Parse(row["volgnummer"].ToString());

newRow["Startdatum"] = DateTime.Parse(row["gestartOp"].ToString());

newRow["Status"] = Hive.Util.HiveEnum.getDescription((CommonEnums.AanvraagStatus)row["status"]);

dt.Rows.Add(newRow);

}

rgTasks.DataSource = dt;

}

protected void RadFilter1_ApplyExpressions(object sender, RadFilterApplyExpressionsEventArgs e)

{

RadFilterSqlQueryProvider provider = new RadFilterSqlQueryProvider();

provider.ProcessGroup(e.ExpressionRoot);

}

protected void RadFilter1_FieldEditorCreating(object sender, RadFilterFieldEditorCreatingEventArgs e)

{

e.Editor = new RadFilterDropDownEditor();

}

But like this of course the dropdown doesn't show any values and only the Status filter shows.

If I add FilterContainerID="rgTasks" to the filter of course I get all fields as I want. However when i select the Status field, I get an exception:

Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

This is kind of expected. the filter already is on the page, I add new one. Viewstate gets broken. Dont know the exact detail, but seems logical to me.

My question is, is it possible to achieve what I want? So override the Status filter which is automatically generated from the FilterContainerID="rgTasks" with a custom filter (combobox containing the available values for the Status colum)

Thanks in advance
