Hi,
I have an application that uses a radgrid control, and is returning over 500 records from a database. I need to enable sorting and paging features. Ideally I would like the grid to store the data client side and NOT do postbacks everytime a page is changed or a column is sorted.
For Telerik controls, the only demo I can find is "Grid - Client-Side Binding and Caching". However, the Databinding location is a webservice. Is there any chance that the Databind location can be a SQL Server database ?

I am following an example of RadGrid - Google like filtering and have a problem with getting other combobox values that user already chosen.
In the demo grid, after I select "USA" in the country filter, I would like to set list of cities and postal codes only for "USA"
I already created session state and use them now, but I am wondering whether there is another way to get values from page to MyCustomFilteringColumnVB.vb??

I'm attempting to do a programmatic insert to a DetailTable in a RadGrid, however I can not find an equivalent "OnInsertCommand" for the DetailTables as I use for the MasterTable.
Is there an equivalent, or is the solution to run the database insert during the onItemCommand event and just verify which detail table is running the insert/edit command? I am using the GridEditCommandColumn within the DetailTable and was hoping there were built in Insert/Edit handlers. I'm using OnDetailTableDataBind to bind the detail table, but didn't see any for Insert/Edit.

I am trying to set up a page, where if I select an item from the first dropdown, it will populate the contents of the second one. This is based on the code from this link
http://www.telerik.com/demos/aspnet/prometheus/ComboBox/Examples/Functionality/MultipleComboBoxes/DefaultCS.aspx
This is what I have
http://www.telerik.com/demos/aspnet/prometheus/ComboBox/Examples/Functionality/MultipleComboBoxes/DefaultCS.aspx
This is what I have
<rad:RadComboBox ID="radDdlOccassion" runat="server" NoWrap="false" LoadingMessage="Loading..." Skin="Vista" Width="210px"
OnClientSelectedIndexChanged="loadSentiment" OnItemsRequested="radDdlOccassion_ItemsRequested">
</rad:RadComboBox>
<br />
<label class="personalize_label">Sentitment:</label>
<rad:RadComboBox ID="radDdlSentitment" runat="server" NoWrap="false" LoadingMessage="Loading..." Skin="Vista" Width="210px"
>
</rad:RadComboBox>
Protected Sub radDdlOccassion_ItemsRequested(ByVal o As Object, ByVal e As _radWebUi.RadComboBoxItemsRequestedEventArgs) Handles radDdlOccassion.ItemsRequested
'Local variables
'Local constants
Const cstrPROC_FUNC_NAME As String = _cstrMODULE_NAME & ".radDdlOccassion_ItemsRequested"
'Try it out
Try
LoadSentitment(e.Value)
Catch ex As Exception
_strErrMsg &= _ErrorHandler.BuildErrorMsg(cstrPROC_FUNC_NAME, ex.Message & Environment.NewLine & ex.StackTrace)
Finally
End Try
End Sub
And in my external js file I have the following function
function
loadSentiment(combo, eventarqs) {
var radDdlSentitment = $find("radDdlSentitment");
var item = eventarqs.get_item();
radDdlSentitment.set_text(
"Loading...");
if (item.get_index() > 0) {
radDdlSentitment.requestItems(item.get_value(),
false);
}
else {
radDdlSentitment.set_text(
" ");
radDdlSentitment.clearItems();
}
}
I am not getting any js errors, but the itemsrequested event of my first dropdown is not being fired....so any help on this would be appreciated.

Hi,
I'm using 2010Q2 and I'm trying to inheriting from RadMultiPage.
So far I had no problem inheriting from the main class, but I have some small issue when I try to create subclasses of its children: the PageViews
I tried the same approach I used for RadTabStrip / RadTab and RadTreeView / RadTreeNode and so far they are working perfectly.
I created a subclass of RadPageView and started adding instances of that subclass to a RadMultiPage.
The problem happens on postbacks: the RadMultiPage recreates instances of RadPageView and not of my subclass.
Am I making some error? Is there another way to subclass RadPageView? Is it not supported?
Best Regards, Andrea Pirola
