I've been using the following code successfully with Q3 2011 SP1 to toggle the selection of RadListBox items when they're clicked (SelectionMode="Multiple") without requiring the use of the CTRL key. After upgrading to Q2 2012 SP1, OnClientSelectedIndexChanged no longer appears to fire if you click on an item that's already selected and it's the only item in the RadListBox that's selected. As a result, if there's only one item selected, the user cannot click on it to unselect it without first clicking on another item (and selecting that item). Is there a workaround to restore the previous functionality?

UPDATE: I've traced the change in behaviour to a bug fix in Q1 2012 SP1: Fixed: OnClientSelectedIndexChanged/ing is always fired on subsequent clicks of the same item

var changed;

function radListBox_SelectedIndexChanged(sender, e) {

if (!changed) {

changed = true;

var item = e.get_item();

if (item.get_checked()) {

item.uncheck();

item.unselect();

}

else {

item.check();

item.select();

}

selectCheckedItems(item.get_listBox());

changed = false;

}

function selectCheckedItems(listbox) {

if (listbox) {

var items = listbox.get_checkedItems();

for (var i in items) {

items[i].select();

}

Async Uploader Failure

We've implemented the rad async uploader, and are having intermittent failures. ie7 and ie8 fail most of the time (this uses the silverlight uploader), and other browsers have been failing occassionally, but chrome and firefox work in most cases. This problem does not occur in our lab environment where there are less security controls. Are there any known issues that we may not know about that could be contributing to the problem?

RadProgressArea shows when editing grid

I have an upload section and a grid showing uploaded files. If you upload a file, then edit something in the grid, when the grid updates, the progress area shows itself while the grid is updating. How do I make it not do that behaviour?

All this is inside of an update panel:

<div style="padding: 3px; border: 1px solid #000000; width: 100%; margin-bottom: 20px;">

Accessing controls in a NoRecordsTemplate block from code behind

I'm trying to access the controls within a NoRecordsTemplate block in my code behind. Doing a search in these forums shows the following code snippet:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

GridNoRecordsItem norecordItem = (GridNoRecordsItem)RadGrid1.MasterTableView.GetItems(GridItemType.NoRecordsItem)[0];

Label lbl = (Label)norecordItem.FindControl("Label1");

}

However, when I try this, the GetItems method returns no items. My GridView control has definitely got NoRecordsTemplate section.

Any ideas why it can't find this?

Thanks for your help,
Dan

Trying to bind date to a datepicker

Hi,

like the title says, I am trying to bind a date to a date picker.

Here is my code:

<telerik:RadDatePicker ID="rdpDateDebut" runat="server" SelectionOnFocus="SelectAll"

Width="100px" DbSelectedDate='<%# Bind("Date") %>'>

</telerik:RadDatePicker>

This is inside a ascx used in an edit form UserControl.

I always got the same error:

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Impossible de créer un objet de type 'System.Nullable`1[[System.DateTime, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' à partir de sa représentation sous forme de chaîne, '', pour la propriété 'SelectedDate'.

My code looks very simple and I don't understand this error.

Sorry, the error is in french.

Thanks.
