RadComboBox Multi-select with unsupported Filter

We have been using RadComboBox with Multi-select, Filter, and MarkFirstMatch. I just now realized that this is unsupported:
http://www.telerik.com/help/aspnet-ajax/combobox-usability-checkboxes.html

Even though it is unsupported, it almost works perfectly. The only issue that I've noticed is that after you check a single item, navigate away, and then come back and select additional items, the textbox is not updated with the newly selected items. For example:

<telerik:RadComboBox runat="server" ID="testComboBox"

CheckBoxes="true" EnableCheckAllItemsCheckBox="true" CheckedItemsTexts="FitInInput"

EmptyMessage="Select Numbers" AutoPostBack="false" Filter="Contains"

MarkFirstMatch="true" NoWrap="true" EnableLoadOnDemand="false"

OnClientTextChange="OnClientTextChange">

<Items>

<telerik:RadComboBoxItem Value="1" Text="One" />

<telerik:RadComboBoxItem Value="2" Text="Two" />

<telerik:RadComboBoxItem Value="3" Text="Three" />

<telerik:RadComboBoxItem Value="4" Text="Four" />

<telerik:RadComboBoxItem Value="5" Text="Five" />

</Items>

</telerik:RadComboBox>

That works well except if you select One, close the dropdown, come back and select Two and Three, when closing it the text will not display correctly- it will revent back to just displaying One. If I remove the Filter, then this issue doesn't occur. I realize that using a Filter is unsupported with multi-select, but coincidentally, if I set another unsupported option, EnableLoadOnDemand="true", then the problem is fixed! In fact, now the entire drop down functionally works perfectly, however, EnableLoadOnDemand="true" forces a postback when you start using the filter by typing into the textbox. This hinders the user's experience as filtering for the desired item(s) is now too slow since a postback occurs with every keypress.

So, my question is, is there any way to achieve the textbox refresh that EnableLoadOnDemand does without using EnableLoadOnDemand? Or, is there a nifty trick to prevent the postback with EnableLoadOnDemand without breaking the text filter? O, is there a supported way to have a multi-select dropdown with checkboxes and filtering?

RadComboBox Issue with CheckBoxes and Filter enabled

Hello All,
I whould like to share with u some trouble with using RadComboBox with CheckBoxes and Filter enabled. The problem is that after uncheck all items Combobox still show one item as checked. Version
Here is my code:

<tr>

<td class="adminTitle">Status</td>

<td class="adminData">

<telerik:RadComboBox EmptyMessage="Select Status" ID="ddlStatus" EnableCheckAllItemsCheckBox="true" Filter="Contains"

CheckBoxes="true" runat="server" Width="298px" ToolTip="Select Status" />

</td>

</tr>

Bind:

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

ddlStatus.SetEnumDataSource<WfApprovalStatus>(exceptOrders.Cast<int>().ToList());

}

Error appear only when I check ONE item.
Steps to reproduce:
1. Open page
2. Check only ONE item in combobox
3. Click in empty space of page (this will close combobox window)
4. Try to uncheck item
5. One more time in empty space
6. You will see that looks like item still left checked but if u open combo box you will see that is not. If u try to send form to server 1 item will be checked

If you remove using filter all works good.

Ajaxmanagerproxy vs button disable

Hello

I have an issue with RadajaxManagerProxy in a Masterpage/contentpage setup.
My goal is to enable/disable (save/update/email) buttons upon saving/updating a telerik report.

The code provided below works just fine when executed under no load.

But during the day with multiple users online, the script stops enabling/disabling the buttons.
(savereport and other heavy rutines still works)

Is my approach incorrect for the task?
Any help would be highly appreciated.

regards

Mark

How to extract RadGrid EditableItem into a DataTable?

Is it possible to extract the edited row from a RadGrid into a DataTable object?

The examples I've seen online show how to extract the data into a HashTable, but once you do that, you lose the data type (string, datetime, ect). We're building a generic grid that can display different tables, so we don't want to have to hard code the columns/data types. If the data is in a DataTable, then it can be passed directly to a SQL stored procedure that accepts a Table Value Parameter.

Viewstate Compression with SSRS 2012 ReportViewer and IE11

A client site is running our ASP.NET 3.5 web-application which includes the Report Viewer control for reporting. They have recently upgraded to IE11, which must be run in native/standards mode.

In order to get the print function of the Report Viewer control working, we have upgraded the Report Viewer control to the 2012 version and have applied patches / updates as per instructions here:
https://blogs.msdn.microsoft.com/selvar/2013/12/20/reportviewer-2012-control-not-showing-print-icon-when-viewed-from-ie-11-desktop-mode/

Part of these instructions are to remove any browser files, however we are currently using the RadHiddenFieldPageStateCompression utility to compress viewstate (specified as per Telerik documentation in the Default.browser file).

If we remove the Default.browser file, the Report Viewer print function operates correctly, but viewstate compression no longer works. Adding the Default.browser file back in, hides the print button on the Report Viewer control.

Is there any way that we can retain viewstate compression and use the SSRS 2012 Report Viewer print function?

Thanks.
