RadNumericTextBox Allows Empty Strings

I'm using a RadNumericTextBox like shown below:

    
                        <telerik:RadNumericTextBox  
        
                            ID="rntbLineNumber"  
        
                            MinValue="1" 
        
                            MaxValue="32767" 
        
                            Type="Number" 
        
                            runat="server"> 
        
                            <NumberFormat DecimalDigits="0" GroupSeparator="" /> 
        
                        </telerik:RadNumericTextBox>

The goal is to insure that the value entered is always between 1 and 32767. However, it allows me to enter an empty string which causes this line to fail on posting.

    
             int myValue = int.Parse(rntbLineNumber.Text);

I'm guessing that I'm supposed to get the value from another property other than "Text" off of the RadNumericTextBox. However, I still feel that the control should be enforcing my input constraints, where a specify a valid range, client-side. In other words, an empty string should populate the field with the minimum value. Is there anyway to do this? Or do I simply have to allow empty strings to be posted?

Self-referencing hierarchy Grid Programmatically

Hello,

I've been trying the Rad Componets for ASP.net and a small issue came up.

I was trying to create a Self-referencing hierarchy grid programmatically on the Page_Init Event.

While I have been successful in creating the grid in the designer view, when I set up it's structure in the Page_Init the hierarchy doesn't seem to be working (ie I get all the records and columns to show normally but they don't have any children).

Is it possible to give me a few pointers on what I need to create the Self-referencing structure on the grid?

PS:My code looks like:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="SelfHierarchyRadGrid._Default" %>

Upgrade to AJAX enabled RadEditor and Treeview

Hi,

The RadEditor (version 5.6.4.0, RadEditor2.dll and Treeview (version 5.1.3.0, RadTreeview.Net2.dll) are currently being used by our team, we are thinking about the possibility to upgrade to latest ajax enabled radcontrol (Telerik.web.UI.dll version 2011.3.1115.35). We are using vs 2010, framework 3.5. What are the steps for upgrading the vs 2010 website ? Anything we need to watch out f( we like to make sure all the existing content will be compatable with the new controls).

Any input will be appreciate, thanks.

Known "script/hash code" issue with deploying RadScriptManager between 32/64 bit machines?

Details are here:
http://www.codeplex.com/AjaxControlToolkit/WorkItem/View.aspx?WorkItemId=15204
http://forums.asp.net/t/1174669.aspx
http://dotnetdebug.net/2008/05/25/
http://www.codeplex.com/AjaxControlToolkit/WorkItem/View.aspx?WorkItemId=14857

I encountered this problem recently by using the telerik script manager with "ScriptCombine" set to true and deploying from a 32-bit machine to a 64-bit machine.

Are you aware of the above issue? I'm assuming your code works the same as the stack trace points to the same area of code:

Assembly "..." does not contain a script with hash code "...".

Telerik.Web.UI

STACK TRACE:

at Telerik.Web.UI.ScriptEntry.Deserialize(String serializedScriptEntries)

at Telerik.Web.UI.CombinedScriptWriter.WriteCombinedScriptFile()

Javascript filters for radcombobox multiple values

I have a need to filter one column based on what the user selects in a rad combo box. It works fine with one value selected but when two or more values are selectd it will not filter correct. I also need to do this client side so server side is not an option. I think the problem is within the "OR" clause. Anyone have any suggestions?
Thanks for any help,
D

<telerik:GridBoundColumn UniqueName="foundin" DataField="foundin" HeaderText="Fields search term matched"

HeaderStyle-Width="215px" ItemStyle-Width="215px" FilterControlWidth="215px"

AllowFiltering="true" ItemStyle-Wrap="True">

<FilterTemplate>

<telerik:RadComboBox ID="radcombo_foundin" runat="server" UniqueName="radcombo_foundin"

Width="200px" OnClientDropDownClosed="filterfoundin" CheckBoxes="true" Filter="Contains" >

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridBoundColumn>

function filterfoundin(sender, e) {

var tableView = $find('<%=rad_SearchResults.ClientID %>').get_masterTableView();

var filter = "Contains";

var i = 0;

var q = "";

while (i < sender._itemData.length) {

q += sender._itemData[i].checked ? sender._itemData[i].value : "";

if (i + 1 < sender._itemData.length) {

if (sender._itemData[i].checked) {

q += " OR ";

}

i++;

}

q = q.substring(q.length - 4) == " OR " ? q.substring(0, q.length - 4) : q;

var hidden = document.getElementById('<%=hf_foundin.ClientID %>');

hidden.value = q;

tableView.filter('foundin', q, filter);

}

Sys.WebForms.PageRequestManagerServerErrorException

Hi All,

I have placed a RadGrid and a RadComboBox in my page. On SelectedIndexChanged event of the RadComboBox, i am searching the data and Binding it to the RadGrid. The problem occurs when i select an option for which there is no Data, and just after that, if I try to select an option which has data in the search criteria the following error is showed:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

If i place an ASP.NET DropDown in place of the RadComboBox, then everything runs fine. One more thing, if i replace the Telerik 2011 ddl's with my old dll's i.e. 2010, then the error is not coming.

Kindly give me some solution for this problem.

Regards,
Raju Sen
