So here is the situation:

I have a RadGrid with 4 columns and am allowing filtering. I'm using the <FilterTemplate> for all four columns and am binding using the NeedDataSource event.

Everything is working great except that for one of the fields I want to actually requery the database rather than just filter. It is a date field and I would rather limit the results from the database on this filter rather than just filter the existing data.

Sooo...here is what I tried:

    
                Public Sub RadComboboxEmployeeDateSubmittedFilter_SelectedIndexChanged(ByVal sender As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)  
        
                    _startDate = String.Format(CultureInfo.CurrentCulture, "1/1/{0} 12:00:00 AM", e.Value)  
        
                    _endDate  = String.Format(CultureInfo.CurrentCulture, "12/31/{0} 11:59:59 PM", e.Value)  
        
                    Session.Item("TransactionLogYearFilter") = e.Value   
        
                    RadGridEmployeeTransactions.Rebind()  
        
                End Sub

RadComboboxEmployeeDateSubmittedFilter is the combobox that is inside the DateSubmitted column <FilterTemplate>, so the code above fires when the user selects an item from the combobox.

Here is my NeedDataSource handler:

    
                Private Sub RadGridEmployeeTransactions_NeedDataSource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs) Handles RadGridEmployeeTransactions.NeedDataSource  
        
                    Dim lTransactions As DataSet = Nothing 
        
                    If UserType <> EnumHelper.UserType.Employee Then 
        
                        Return 
        
                    End If 
        
                    Try 
        
                        lTransactions = MiBenefitsHelper.GetEmployeeTransactions(GroupNumber, _  
        
                                                                                 FamilyNumber, _  
        
                                                                                 _startDate, _  
        
                                                                                 _endDate)  
        
                        RadGridEmployeeTransactions.DataSource = lTransactions  
        
                    Catch ex As WcfException  
        
                        PanelEmployeeTransactionLog.Visible = False 
        
                        PanelUpdateStatus.Visible = True 
        
                        LabelUpdateStatus.Text = "There was an error returning your transactions and they cannot be displayed at this time. EBMS has been notified of the problem and will have it resolved as soon as possible." 
        
                        LabelUpdateStatus.ForeColor = Color.Red  
        
                        ExceptionPolicy.HandleException(ex, "Global Policy")  
        
                    End Try 
        
                End Sub

As you can see it is referencing the _startDate and _endDate fields which get populated when the user makes a selection from the dropdown.

The problem is that RadGridEmployeeTransactions.Rebind() does not cause the RadGridEmployeeTransactions_NeedDataSource event to fire, which means the database is not re-queried and the results are not filtered.

How do I go about forcing the RadGridEmployeeTransactions_NeedDataSource event to fire so that it queries the database with the correct _startDate and _endDate values??

Thanks!

Using RadionButtons inside PanelBar

I have been tasked to use the PanelBar with Radio Buttons.

The mock up below pretty much explains my needs. Attendee logs in. Then they see Thursday, Friday, Saturday, and Sunday as Top Panel bar items. When they click on Thursday, the time slot followed by courses represented with Radio buttons is displayed for user to select a course taken for that time slot.

I have this all working with a combo box that the user selects which day they want and then the list shows. However they have not changed there mind and want to use the PanelBar.

Any how to and code examples will be welcome, I didn't find anything to help with this yet.

Webservice data binding example demo

I have attempted to recreate this demo on my local PC with the northwind DB:

http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/programmatic/defaultcs.aspx

Unfortunately, the clientside call in the client pageload event:

PageMethods.GetData(0, tableView.get_pageSize(),

does not initiate the following serverside code:

public static List<Employee> GetData(int startIndex, int maximumRows,

string sortExpressions, List<GridFilterExpression> filterExpressions)

this function fails here:

function RadGrid1_RowDataBound(sender, args) {

var radTextBox1 = args.get_item().findControl("LastName");

radTextBox1.set_value(args.get_dataItem()["LastName"]); fails here

}

Can someone please explain why the client side call does not work or provide me with a better example of clientside data binding.

Thanks in advance.

AccessKey not working in Firefox or Safari

I can only get the AccessKey funcionality of the RadTreeView to work in IE8. It is not working in Firefox 3.5, or Safari 4.0.

I copied and pasted the example provided under the control demo, and added accesskey="W".

When I press Alt+W in Firefox or Safari, nothing happens. The treeview is not focused, and I cannot use the arrow keys for navigation.

New CSS style for Combobox label

I'm trying to define a CSS style to use in Combobox label which has WebBlue skin. I read about style definition in the forum and I added to my CSS file this code:

.RadComboBox_WebBlue .MyLabelStyle.riLabel

{

font-family: Verdana,Helvetica,Arial;

font-size: 10pt;

color: Navy;

}

I assigned MyLabelStyle to the LabelCssClass property but nothing happens, the label style of the combobox doesn't change

Any suggestion?

OnClientCollapsed fired when sliding pane docked (pinned)

Hi,

I need to react when a RadSlidingPane is expanded or collapsed.
To this end, I have the following declaration:

<telerik:RadSlidingZone ID="rszRight" runat="server" Width="22px" SlideDirection="Left">

<

telerik:RadSlidingPane ID="rspDetails" Title="Task Details" runat="server" Width="170px" OnClientCollapsed="rspDetails_Collapsed" OnClientExpanded="rspDetails_Expanded"

>

...

Simply hovering over the pane's tab causes the OnClientExpanded event to fire (see green arrows in attachment). This is as expected.
The problem is that the OnClientCollapsed event is firing when I click on the pin (dock) icon - not what I expected (see red arrow).
See the attached screenshot and note the console log at the bottom.

Am I doing something wrong?

Thanks in advance for any suggestions.

RadProgressArea not working in Windows Server 2003 (IIS 6)

Hello Telerik Team,

We would like to inquire regarding the RadProgressArea we used this to create a custom progress bar for our web application. The Progress bar functionality of the application is working as expected, or the progress bar is visible in the web application when deployed in Windows Server 2008 (has IIS 7 installed) but not in Windows Server 2003 (has IIS 6 installed). May we ask if there are known limitations for RadProgressArea specifically for OS version or IIS?

Thanks! :)
