Multiple RadDropDownLists in Batch edit mode

Hello, I am new to your fourm as well as fairly new to using the Suite of Tools. My situation is that I currently have RadGrid which is set to batch edit mode and has two drop downs. The first drop down has a list of items that is populated by an objectdatasource and the second list will be populated based on the selection of the first drop down and the selectedvalue will then be passed into the object datasource of the second drop down. I have worked at tackling this from multiple approaches...having an autopostback on the first drop down and once that fires then well do a javascript function where it will take the value of the selected item and pass it to a hidden value and I can access the hidden value ino the GridsPreRender and find the two controls and populate the second drop down. This sort of works as the second drop down is being populated correctly but every time I have to make a selection I have to click the griditem once and it will highlight and do nothing and then if I click it again it will allow me to make my selection. The other problem is that after I make a selection on my first drop down and the postback occurs it automatically reverts back to the original selection....the user is doing this when they are trying to edit a current list of dropdowns. I haven't worked out or seen how it will behave if I try to add a new row. Any thoughts?

Thanks for any and all help in advance,

Ramey

How to disable editing RecurringApppointments for some events

I need to prevent some users from modifying some recurring events but allow them to edit others based on role permissions. I've built a function that gets called on "Edit" event but the problem is "Edit" event gets called when editing and also adding an event. I need to allow adding events but prevent editing/modifying existing recurring events. Currently scheduler_edit function prevents both editing and adding events.

Here is my stripped down scheduler_edit function:

function scheduler_edit(e) {

if (!e.event.CanBeEdited) {

e.preventDefault();

}

Visual Studio JavaScript intellisense with Rad controls

Greetings,

I'm doing heavy client side work with Rad controls, specially the grid. I became tired from copying and pasting functions names from the console and hoped that Visual Studio intellisense would help me.
I tried adding the Telerik.Web.UI.Common.Core.js file downloaded from the CDN to my Visual Studio references but intellisense broke.

Does Telerik have a vsdoc (or any other format) definitions file for the library that can be referenced from VS to ease client side development?

Error when double clicking empty space

I am updating a project to the latest version of Telerik UI for AJAX, and have noticed that if Idouble click on empty space below my text in the editor I get a javascript error "Unable to get property 'nextSibling' of undefined or null reference", relating to the following segment of code:

var h=function(o){while(!o.nextSibling){o=o.parentNode;
}return o.nextSibling;
};

As I have been unable to determine the source of this problem I am hoping you can help me out.

RadEditor Client side validation

Hi All,

I am facing problems with client side validation of RadEditor.
I want to put a check on length of the string entered in editor.

Following is the code, I have written:

    
            ========ASPX========

                        </Tools> 
        
                    </telerik:RadEditor> 
        
                    <asp:Button Text="SAVE" ID="button16" OnClick="Save_Click" 
        
                        runat="server" ValidationGroup="group1" /> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            ========CODE BEHIND======== 
        
                public partial class EditorValidation : System.Web.UI.Page 
        
                { 
        
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                    } 
        
                    protected void Save_Click(object sender, EventArgs e) 
        
                    { 
        
                        int len = editor1.Content.Length; 
        
                    } 
        
                }

To put check on length, I used function get_html() and get_text(). But length of string returned by these function is sometimes smaller than length of server side attribute "Content".
Then I found online demo(http://demos.telerik.com/aspnet-ajax/editor/examples/validators/defaultcs.aspx) which had implementation like function "ValidateEditor1". But that also returned smaller length.

I observed that this problem consistently occurs with strings spanning over multiple lines. You can try this by entering any multi-line string in the editor.

So I think I will be able to solve this problem if I find some api on client side, which returns string exactly equal to the one returned by server side attribute "Content". Can anyone provide more insight into this problem?

Regards
Shrikant

How do I set the data source for built in field editors?

Specifically a RadFilterDropDownEditor, but I will also need date editors as well. I can't find any good documentation explaining how to set something up. My current strategy is based off of the code here: http://docs.telerik.com/devtools/aspnet-ajax/controls/filter/field-editors/programmatic-creation. I have to set the field editor's values with a list, but using the code below, there are no values in the drop down. I have also seen the code here but it is a completely different and unexplained approach, and involving data tables is, in my opinion, bad.

Here is essentially what I have:

<telerik:RadFilter runat="server" ID="rfFilter" RenderMode="Lightweight" FilterContainerID="RadGrid1" ShowApplyButton="False" ViewStateMode="Enabled" OnApplyExpressions="rfFilter_ApplyExpressions"/>

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadFilterDropDownEditor districtFilter = new RadFilterDropDownEditor();

rfFilter.FieldEditors.Add(districtFilter);

statusFilter.FieldName = "District";

statusFilter.DataType = typeof(string);

var list = new ArrayList(GetDistrictList());

statusFilter.SetEditorValues(list);

}
