I am using a RadDatePicker within a custom control. What I need to do is to trigger an event when the date changes. So I've added an OnTextChanged even on the DateInput. And I've set AutoPostBack = TRUE, but I never seem to get the textChanged event to fire. Additionally, the text doesn't actually get updated in the datepickers date input until I pick a date, and then put my cursor back into the control again.

But if I remove this event and AutoPostBack setting the text box is updated, but how can I caputre this event?

I need the custom control (which contains the radDatePicker) to raise an event on the container page/control based on teh change of selected date in the datepicker -- either when the user picks a date on the calendar popup, or manually enters a date in the text dateinput field.

I also tried using onSelectedDateChanged even of teh DatePicker, but again, if I set AutoPostBack = true this is causing the dateinput text field not be correctly updated.

[Solved] GridNumericColumnEditor Currency Formatting in Edit Mode

I have assigned a GridNumericColumnEditor to a GridNumericColumn as follows:

    
            <telerik:GridNumericColumn DataField="PaymentAmount" DataType="System.Decimal"   HeaderText="Payment Amount" UniqueName="PaymentAmount" DataFormatString="{0:C2}" NumericType="Currency" ColumnEditorID="GridCurrencyColumnEditor">  
        
            </telerik:GridNumericColumn>

I have defined the GridNumericColumnEditor as follows:

    
            <telerik:GridNumericColumnEditor ID="GridCurrencyColumnEditor" runat="server">  
        
                    <NumericTextBox Culture="English (United States)" LabelCssClass="" InvalidStyleDuration="100" 
        
                        Type="Currency" runat="server">  
        
                        <NumberFormat AllowRounding="True" KeepNotRoundedValue="False" DecimalDigits="2"></NumberFormat> 
        
                    </NumericTextBox> 
        
            </telerik:GridNumericColumnEditor>

While in edit mode, the currency fields are not being displayed with two decimal places. If I enter 1,234 I get $1,234 displayed when I am expecting to get $1,234.00. If I enter 1,234.1234 I get $1,234.1234 displayed when I am expecting to get $1,234.12.

While in display mode, the formatting works properly based on the DataFormatString attribute in the GridNumericColumn.

Am I doing something wrong with the number formatting?

Change to TreeView node not "sticking"

I'm using your treeview in this web page.

Imagine the user is editing the Description TextBox. He changes the value to something else and then immediately clicks on another node in the treeview. In the TextChanged event handler of the TextBox I update the treeview node's Text property. It *appears* to change it but then when the postback occurs and the NodeClick event handler for the TreeView runs, the change seems to have disappeared.

Why would this be?

Grid Multi-Row Edit

Hello,

I want the entire list of rows, for the underlying data, bound to the RadGrid in edit mode. I'm trying to create an Excel like interface and I wanted the RadGrid for the client-side binding. Can this work, and can the RadGrid do what I want? I figured I manually loop through each row, access the underlying control, and update my data objects...

Thanks.

FindControl for CommandItem controls

I have two sections on my page: a set of controls on the top of the page that specify various controls for searching data, and a RadGrid below it that shows the results.

Inside the CommandItemTemplate of the RadGrid, I have a checkbox.

In an eventhandler not directly related to the grid itself (a button click) I need to get a reference to the Checkbox inside the command item template, but I can't seem to find the right way to get a reference.

Any suggestions? Here's a couple of snippets of different ways I tried to get a reference from the button click event.
The inner part of the for loop doesn't get hit because when inside the button click event handler, the if Item si GridCommandItem is always false.

    
            <CommandItemTemplate> 
        
                <asp:CheckBox ID="chkMyCheckBox" Style="float: left" runat="server" Text="My Checkbox" TextAlign="Right" AutoPostBack="true" OnCheckChanged="chkMyCheckBox_CheckChanged" /> 
        
            </CommandItemTemplate> 
        
            Dim chk as CheckBox = DirectCast(dgMyGrid.FindControl("chkMyCheckBox"),CheckBox) 
        
                        For Each Item As GridItem In dgMyGrid.Items 
        
                            If Item Is GetType(Telerik.Web.UI.GridCommandItem) Then 
        
                                Dim CommandItem As GridCommandItem = DirectCast(Item, GridCommandItem) 
        
                                Dim Header As GridTHead = DirectCast(CommandItem.NamingContainer, GridTHead) 
        
                                Dim chk1 As CheckBox = DirectCast(Header.FindControl("chkMyCheckBox"), CheckBox) 
        
                                Dim chk2 As CheckBox = DirectCast(CommandItem.FindControl("chkMyCheckBox"), CheckBox) 
        
                            End If 
        
                        Next
