We use RadTextBoxes in a form with a countdown timer for testing purposes. After so much time elapses, if the user has not submitted the form, it is automatically submitted for him.
This form worked great until 1 or 2 updates ago when the RadTextBox started returning an empty value to the server on occasion. Since the issue was sporadic we checked many other things before we finally realized it only happened when the form auto submitted. Then we figured out it was a blur issue with RadTextBox.
In the meantime, this has caused us major problems as examinees type in an essay for 15 minutes and then it is all gone because they were not lucky enough to click outside the RadTextBox.
Now that we know what the problem is, we can work around it with a box.blur() or box.set_value(box.get_textBoxValue()) before postback.
I love these controls but this behavior is a serious breaking change and makes no sense. There should be no requirement to blur a RadTextBox to get its value to the server.
Please fix this.
Thank you.

I suggest you to review your online demo in "Time picker/DateTime picker" section and add more demo/info re. RadDateTimePicker. Specifically, I would suggest:
- Add "DateTimePicker - First Look"
- MOST IMPORTANT: Add DateTimePicker range validation as it's different from TimePicker!

I have a RagGrid. On click of "Add New", I want a customized form. Is this possible?
I tried the following but did not work!
protected void _RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
if (e.CommandName == RadGrid.InitInsertCommandName)
{
e.Canceled = true;
this._RadGrid1.EditIndexes.Clear();
e.Item.OwnerTableView.EditFormSettings.UserControlName = "AddControl.ascx";
e.Item.OwnerTableView.InsertItem();
}
}

I'm doing some work in a javascript function and part of it is to remove (or add) an attribute from a RadTextBox. Looking at the list of properties and methods on the Client Object page, I don't see how to do this. I've seen forum posts reference the _textboxelement property of RadTextBox control like so:
I was wondering if this would work. If so, how?
I'm trying to add or remove the data-bind attribute on a textbox.
Thanks.
<script type="text/javascript"> function setToolTip() { var RadTextBox = $find("<%= RadTextBox1.ClientID %>"); // Get the textbox client object RadTextBox._textBoxElement.title = "Changed Tooltip"; } </script>I was wondering if this would work. If so, how?

Hi,
I have an application with some telerik:RadComboBox and asp:RequiredFieldValidator to validate empty value. But it's not working and it's not validating. I checked the radscript manager and I have an error (Error Creating Control).
I had the application with NET Framework 2.0 and I changed to NET Framework 3.5. I have instaled Telerik ASP NET Q1 2010
Is it compatible that version of telerik with .NET framework 3.5?
What does the problem with combobox validation?
this si my html:
<telerik:RadComboBox ID="lstCountry" runat="server" AutoPostBack="True"
onselectedindexchanged="lstCountry_SelectedIndexChanged" SkinID="DropDownList"
TabIndex="17" Width="240px" >
</telerik:RadComboBox>
<asp:RequiredFieldValidator ID="rfvCountry" runat="server"
ControlToValidate="lstCountry" ErrorMessage="Country is required" InitialValue=""
SkinID="RequiredFieldValidator" ValidationGroup="vgpSave" Text="*">
</asp:RequiredFieldValidator>
Regards
Jose

When I try to open a radwindow, the border is disappearing...If I use similar code on another page, it works just fine...
See attached image, here is the javascript code:
4/13/2012 UPDATE:
This seems to be happening on IE9. I hit the page from IE8 and it seems to be working. With that being said, I have another page with a popup radwindow and it appears just fine using IE9. I am having this problem just on one page.
Thanks
See attached image, here is the javascript code:
function ShowEditForm(id, boxid, rowIndex, authToken, apiKey) {
var grid = $find("<%= radgrid.ClientID %>");
var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
grid.get_masterTableView().selectItem(rowControl, true);
var url = 'EditReportPage.aspx?id=' + id + '&boxid=' + boxid + '&authtoken=' + authToken + '&apikey=' + apiKey;
var wnd = window.radopen(url, "EditReportDueDateData");
wnd.setSize(550, 300);
wnd.set_visibleStatusbar(false);
wnd.center();
return false;
}

Hi,
I am creating a custom control in C#. this control will have a radcomboBox and lable in a html table. When you select an item in the radcomboBox, the selected item text will be diplayed in the lable. But when I try to render, I am getting error.
Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

RadComboBox
currencySelector = new RadComboBox();
currencySelector.ID = "dsfdsf";
//currencySelector.Items.Add(new Telerik.Web.UI.RadComboBoxItem("Australian"));
htmltableCell.Controls.Add(currencySelector);
htmlTableRow.Cells.Add(htmltableCell);
.....
currencyConverterTable.Rows.Add(htmlTableRow)
currencyConverterTable.RenderControl(output);
What am I doing wrong here???
Thanks,
