Questions on UI for ASP.NET AJAX Forum

Hi, all.

I have a question regarding the behavior of the RadRating control. I have a dynamically-created RadPanelBar that grabs its header text from a SQL server and then passes that to an ITemplate to create the custom header control. Certain items from our database will also have a rating in the header as well.

For the rating itself, have a custom image URL for each rating item (a star with a different letter, depending on the index of the item being created). It's been decided that showing the star/letter icons for each selected item will make the page look too busy when there are several high-rated items.

So here's the question: is it possible for a rating to have multiple SelectedImageUrl properties for a rated item? For example, if the rating is 4 stars, can the control be set to show 3 filled stars and have the 4th be the star with the letter in it?

ItemCollection edited client side not available serverside

I've been able to edit the collection of client side items of the drop down list.
My problem is, these edits aren't accessible on the server side.
When a postback occurs, I only see the original list item collection.

I don't see what I've done wrong. Here's what I've got so far:

var ddl = $find("<%=_ddlLidsIndicators.ClientID%>");

ddl.get_items().clear();

var selectItem = new Telerik.Web.UI.DropDownListItem();

selectItem.set_text("Select...");

ddl.get_items().add(selectItem);

$.each(data, function (index, value) {

var newItem = new Telerik.Web.UI.DropDownListItem();

newItem.set_text(value);

newItem.set_value(index);

ddl.get_items().add(newItem);

});

var otherItem = new Telerik.Web.UI.DropDownListItem();

otherItem.set_text("Other");

ddl.get_items().add(otherItem);

ddl.commitChanges();

Adding Items to RadDropDownList on ClientSide

Hello,

I'm trying to manipulate the items in my raddropdownlist via jquery.

I found this page with documentation:
http://www.telerik.com/help/aspnet-ajax/dropdownlistitemcollection-client-object-api.html

the Add() method requires a DropDownListItem parameter.
But I can't find any documentation on how to declare a var of that type.
Is it in a namespace somewhere that I haven't found?

Please advise.
Thank you.

Filter on Hierarchical grid

Hey

I'm using Kendo Hierarchical grid, just as one of listed in your demos (http://demos.telerik.com/aspnet-mvc/grid/hierarchy). My issue is, I want to apply a filter on one of columns (on parent grid) such that it will also be applied on Child grid column. My issues are:

1. How do i know if there is filter applied on parent grid column, since there is no such even handler for filter on grid.
2. I want to data appear in child grid columns(if exists), even if entry doesn't exist on parent grid column

I did some experiments by passing the filter collection from parent grid to child grid (since both have similar schema), but again, but couldn't sort out the answers for those two questions

Thanks

One of the requirement of our client is Excel export and Import data to radgrid. I am using RADGrid in BatchEdit mode,the data from the grid will be exported as excel. This has been done already using openxml. The data in the exported excel will be edited by the user. He may add new data. Once done the changes in the excel, the user wants to import the excel in Radgrid batchedit and save the changes in database.

Creating RadDateTimePicker dynamically

Hi,

I have a requirement to create a number of server controls (e.g. asp textboxes etc.) as well as RadDateTimePickers dynamically (e.g. at runtime) on a webform. I'm using the same approach to create instances of both types of control (see below):

TextBox txt = new TextBox();

txt.ID = "someid"

txt.CssClass = "my-textbox-class";

ph.Add(txt); //add to placeholder control

RadDateTimePicker dtp = new RadDateTimePicker();

dtp.ID = "adifferentid";

dtp.Width = new Unit(200, UnitType.Pixel);

dtp.DateInput.CssClass = "my-datepicker-class";

dtp.TimeView.Interval = new TimeSpan(0, 30, 0);

dtp.TimeView.Columns = 6;

ph.Add(dtp); //add to placeholder control

Because they're created dynamically I recreate the controls every time there is a postback. I've noted that the regular asp controls maintain any values entered into them automatically after they're recreated however the RadDateTimePickers don't. Is there something I'm missing?

Thanks
