Can I get a server side notification of a row selection

Hi

I just cann't seem to wire up my grid to issue a server side event on a row selection.

I see there is a client side event.

Do I have to use that and then issue a post-back myself?

TIA

error after error after error trying to launch Sales.Dashboard demo

I have been trying to launch the Tekerik.Sales.Dashboard demo.

I have updated the Telerik.OpenAccess references to point to the installed dlls instead of the ones that came with the demo project.

I am getting the following errors now:

Error 1 Using the generic type 'Telerik.OpenAccess.Query<T>' requires 1 type arguments C:\Users\myusername\Downloads\SalesDashboardSource\SalesDashboard\Telerik.SalesDashboard.Web\App_Code\SalesDashboardService.cs 11 26 C:\...\Telerik.SalesDashboard.Web\

Error 1 The type or namespace name 'Web' does not exist in the namespace 'Telerik' (are you missing an assembly reference?) C:\Users\myusername\Downloads\SalesDashboardSource\SalesDashboard\Telerik.SalesDashboard.Web\App_Code\ToolTipWebService.cs 14 15 C:\...\Telerik.SalesDashboard.Web\

Is there any link that shows how to get rid of all these errors and launch this demo app??????????????????????????

Thanks

How do i get the Total Grid Item Count when Paging is enabled?

Hi,
I am trying to get the total items count on my grid (total count of all the items in all the pages of the grid) in my code behind when Paging is enabled.

My data source for the grid returns 17 rows and the data is displayed in 2 pages.
When i do an Items count it only returns me 10 (since my page size is 10)
i tried this code which was suggested in this forum -


<telerik:RadGrid ID="GridInvoiceDetailsPO" runat="server" AllowPaging="True" 

AutoGenerateColumns="False" PageSize="10" Visible="True" Skin="Outlook" 

PagerStyle-Mode="NextPrevAndNumeric" PagerStyle-AlwaysVisible="true" 
.... />




int

i = GridInvoiceDetailsPO.Items.Count;

GridInvoiceDetailsPO.AllowPaging = false;

GridInvoiceDetailsPO.Rebind();

int j = GridInvoiceDetailsPO.Items.Count;

GridInvoiceDetailsPO.AllowPaging = true;

GridInvoiceDetailsPO.Rebind();

int k = GridInvoiceDetailsPO.Items.Count;

But i, j and k all return 10. is there something i am doing wrong?
Also i dont just want to get the total count, i want to iterate through the collection and get/set some data.

}

Just in case you guys want to know what kind of datatype that I'm binding it to the grid. It's the arraylist.

Could you please tell where in the code that I miss ? Right now when I click on the "Insert new record " It show me the edit form . But once I click on the update button . There is nothing happen.

Thank you so much.

How to Use the Built-In Export Button When Using a Dynamic RadGrid?

I have a RadGrid which is created at runtime and added to a place holder control.

I set the commandItemSettings.ShowExportToExcelButton = true and the built-in export button appears.

After the grid is created I call the Rebind() method so that my NeedDataSource event is raised (Advanced Data Binding):

I'm using NeedDataSource event:
void radGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
this.radGrid.DataSource = this.dataSource;
}

When I click the Export to Excel button nothing happens.

How should I implement this or use it so that the export works?

Many thanks,

Grid

RadScheduler and WebService Binding(MVC)

Hi!

We have implemented a custom solution with the RadScheduler with WebService(and a DbSchedulerProvider) binding using the online demos.

I have one question: after the Appointment save process the GetAppointments method is re-called and it calls the LoadResources(Apppointment apt) method.

What should this method return? All the Scheduler Resources or just the Appointment resources?

It all seems fine until we try to edit/update the Appoinment as the Resources doesnt show up with the selected resources(in DropDownLists). We are only returning the Appointment resource collection.

Best regards

Scheduler

RadMaskedTextBox incorrectly hiding the value on ASYNC Postback

I have a masked text box inside an update panel. The masked text box has hideonblur set to true, and uses an empty message. When the page loads, the masked text box displays the empty message correctly. When I type a value in the masked text box, the empty message is correctly hidden.

I then click a button. The click event of this button is a trigger on the update panel that contains my masked text box. The page is asynchronously posted back, and when it finishes, the masked text box now displays the empty message instead of the value that was entered! If you click in the masked text box to give it focus, then tab out, the empty message is now hidden, and the value again displayed.

How can I keep my masked text box inside the update panel and not have it incorrectly hide my value? The only solution I've found is to remove the empty message AND hideonblur, which causes the mask to always display, which is not what I want.

I am using the standard MS AJAX panels. Any help is appreciated.
