Hello,

I am trying to validate a valid item is typed into one of my combo's with load on demand enabled and I am having a hard time with the javascript. I want to re-use a function for multiple combobox's.

    
                    function ValidateComboUser(source, args)    
        
                    {            
        
                        var combo = $find(source.ControlToValidate.ClientID);   
        
                        args.IsValid = ValidateCombo(combo);  
        
                    }            
        
                    function ValidateCombo(combo)  
        
                    {  
        
                       var isValid = false;    
        
                       var text = combo.get_text();    
        
                       var item = combo.findItemByText(text);    
        
                       if (item)    
        
                       {    
        
                           isValid = true;    
        
                       }   
        
                       return isValid;  
        
                    }  

            Can someone please help me with a way to get the combo box being validated through the function params?

            Thanks

Filtering not working

Hi,

I'm new with Telerik. I took a demo and modified it for my own use, as I was going along, the filters were working, now they are not. I have custom and standard filters. They do nothing but generate an error. When running I get an error in VS2013, when I try to access one of the filters:

Error: Sys.WebForms.PageRequestManagerServerErrorException: ORA-00936: missing expression

Obviously this is an oracle error.

None of my filters are working and they all return a similar error

Can someone provide some guidance on what to check for?

Thanks

RadGridNamespace is not defined - Only on local computer

Well, I left work last night and everything was fine. Came back and I started getting the "RadGridNamespace is not defined" error, and my data was exploded all over the screen. I didn't make any changes, and I even rolled back my code to a version we were using over a week ago, and the same thing is happening.

The grid works fine on all of our servers, and works for our other developers, just not me.

Any ideas?

How to: Attach an event to a GridDropDownColumn

Hi all,

I have a control that inherits the Telerik.Web.UI.GridDropDownColumn like:

                             
                [DefaultProperty("Value")]         
                [ToolboxData("<{0}:myGridDropDownColumn runat=server></{0}: myGridDropDownColumn>")]         
                public class myGridDropDownColumn : GridDropDownColumn         
                { ... }        

I need to attach an event to fire up on Selected Value is changed. How can I accomplish this?

my control does not give me the OnColumnChange Event [url: http://www.telerik.com/help/aspnet-ajax/telerik.web.ui-telerik.web.ui.griddropdowncolumn_members.html] (am I missing something?)

and there is no Attribute propertie to attach a javascript call like:

myGridDropDownColumn myDrop = new myGridDropDownColumn();
myDrop.Attributes.Add("onchange", "alert('event fired!');");

My objective in this case is to create a dropDown that, when the selectedValue changes, it would populate the other DropDown in the same row: row[ x ].column[ 2 ], any idea is there is a tutorial about this technique... I can't find it anywhere around :(

LoadRtfContent and FormView

I put a RadEditor inside a Formview, which is inside a RadAjaxPanel. I use the following to load RTF:

protected void Unnamed_DataBinding(object sender, EventArgs e)

{
var txt = sender as RadEditor;

txt.LoadRtfContent(@"{\rtf1\ansi\deff0
{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}
This line is the default color\line
\cf2
This line is red\line
\cf1
This line is the default color
}
");
}

The issue is the editor is displaying the text with HTML tags instead of formatted text. I am wondering if this is an issue with the trial version (still waiting for my company to process the purchase) since it adds warning text to the content automatically.
