I have the following,

<telerik:RadListView ID="RadListView1" runat="server" DataSourceID="SqlDataSource2" OnSelectedIndexChanged="RadListView1_SelectedIndexChanged">

<ItemTemplate>

<label id="dftLabel">Templates</label><br />

<asp:LinkButton ID="LinkButton1" runat="server" Text='<%#Eval("title")%>' CommandName="Select" CommandArgument='<%#Eval("templateID")%>'></asp:LinkButton>

</ItemTemplate>

</telerik:RadListView>

and I'm having a hard time getting the value of CommandArgument.

Any suggestions?

Thanks.

Timer start via javascript

Hi there,

I recently updated to a new version of telerik and I noticed that the telerik timer no longer exists.

I started using the .NET timer and I am facing some issues.

Previously I was able to start and stop the timer via javascript:

function StartFilteringTimer()

{

<%= tmrFilter.ClientID %>.Start();

}

function StopFilteringTimer()

{

<%= tmrFilter.ClientID %>.Stop();

}

What would be the alternative to this in my situation?

Thanks in advance,

Kevin

2 level tabstrip problem

Hi folks, quick little problem

I have a two level tabstrip. When I click on the tabitem that has the second level, the second level tabs do not show.
This ONLY occurs if the top level tab has navigateurl

Sample below.
How Do I get around this, so that the second level menu shows?

<telerik:RadTabStrip ID="RadTabStrip1" runat="server">

<Tabs>

<telerik:RadTab runat="server" Text="Root RadTab1" NavigateUrl="webform1.aspx" Selected="True">

<Tabs>

<telerik:RadTab runat="server" Text="Child RadTab 1">

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Child RadTab 2">

</telerik:RadTab>

</Tabs>

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Root RadTab2">

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Root RadTab3">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

Grid update command id

I'm trying to pull the data from the Id column of the selected row within the update command as follows

Protected Sub radgrid_Update(ByVal sender As Object, ByVal e As GridCommandEventArgs) Handles radgrid.UpdateCommand

Dim selectedRow As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

Dim rowNo As Integer = selectedRow.ItemIndex

Dim id As String = selectedRow.Item("id").Text

End Sub

This allows me to get the row index but not the data within the id column.

Any suggestions are greatly appreciated.

Thanks.

RadFilter with custom EntityDataSource

I've been working through getting RadFilter to work with our datasource class, derived from EntityDataSource. The RadFilter throws a null ref on apply:


[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Web.UI.RadFilter.ApplyFilterExpressonsOnDataSource() +157
   Telerik.Web.UI.RadFilter.HandleApplyCommand() +218
   Telerik.Web.UI.RadFilterCommandEventArgsFactory.HandleCommand(RadFilter ownerFilter, Object commandSource, RadFilterCommandEventArgs args) +74
   Telerik.Web.UI.RadFilter.OnBubbleEvent(Object source, EventArgs args) +319
   System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) +37
   System.Web.UI.WebControls.Button.OnCommand(CommandEventArgs e) +125
   System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +167
   System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5563

After working through all our modifications to try and figure out what was causing this by process of elimination I was disappointed to find that the RadFilter simply throws it on ANY derived DataSource. All you need to do is create an empty class which extends EntityDataSource, point a RadFilter at it, and it fails to apply with the above exception.

Is there a way to work around this?

Searching the RadListBox

Hello!

I want to build a RadListBox with loadOnDemand functionality. A requirement is that the scrollbar should be on the correct position, so in a box of 20k items, when scrolling to number 10k the scrollbar should be halfway. The dataset is available in the code-behind. So far so good.

The thing is, I need to be able to do a search its items. The search should be fired to the server, where I can determine the current position or page of the listbox by doing a search on my dataset.
For example in a separate textbox (or preferrably in some built in popup in the listbox) I want to do a search with text '200'. What should happen is the following; the listbox should load the first page with the first item beginning with '200'. The scrollbar of the listbox should still represent the current position of the total of records.

Can you give me any directions how to implement this?

Greetings,

Hoekstra
