Thnx for your reply
I tried the demo as
put ValidationGroup="imageEditorValGroup" for radgrid

<ValidationSettings ValidationGroup="imageEditorValGroup" EnableValidation="true" CommandsToValidate="PerformInsert,Update" />

and an other point at code behind i bind a custom validator as

    
             protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)  
        
                    {  
        
                        if (e.Item is GridEditableItem && e.Item.IsInEditMode)  
        
                        {  
        
                            RadUpload editorRadUpload = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("Upload").ContainerControl.FindControl("RadUpload1") as RadUpload;  
        
                            TableCell cell = (TableCell)editorRadUpload.Parent;  
        
                            CustomValidator validator = new CustomValidator();  
        
                            validator.ErrorMessage = "Please select file to be uploaded";  
        
                            validator.ClientValidationFunction = "validateRadUpload";  
        
                           // validator.ValidationGroup = "imageEditorValGroup";  
        
                            validator.Display = ValidatorDisplay.Dynamic;  
        
                            cell.Controls.Add(validator);  
        
                        }  
        
                    }

any button clicked on the page that contains usercontrol which includes the radgrid is not go to validate function
but also inside grid any validate function fired...
so i found a way like this
i gived validationgroup for the controls outside grid this accomplished what i want ,for now..
