Raddropdownlist finditembyvalue not working

Hi,

There is a Raddropdownlist (Q1 2013 beta) which is populated using a data table from server side page load. In a radbutton click, I am using the FindItemByValue method to get the item but I am getting an error which seems like there is no such method associated with this control.

RadDropDownListItem item = RadDropDownList1.FindItemByValue("101");

Thank you,
Damian Hague

RadGrid Filtering not working as it should

I have a radgrid and have enabled filtering. I have restricted the filtering to contains only. The problem is that when I enter in some filter text it fires the ItemCommand event which is fine but, it does not filter the grid. If I re-type the filter string again it fires the ItemCommand event again and the second time and any more subsequent attempts work as expected resulting in the grid being filtered. This is so wierd and I have no idea whi I have to type in a filter string twice to get it to work.

protected void policeGrid_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "Select")

{

var stationId = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["station_id"];

Session["station_id"] = stationId;

radAjaxMgr.ResponseScripts.Add("radopen('information.aspx','null')");

}

[Solved] Update RadGrid1 from RadGrid2 with RadAjaxManager

I have a webpage, with a RadAjaxManager, a RadAjaxLoadingPanel which contains RadGrid1, a second RadAjaxLoadingPanel which contains RadGrid2. RadGrid2 has a template column which has a couple controls and an asp:ImageButton. The desired functionality is when the ImageButton is pressed, it copies the rowdata and inserts it into RadGrid1. This process works, however the row is not displayed in RadGrid1 until a page refresh happens. Is there a way to trigger the reload of RadGrid1 after the ImageButton (from RadGrid2) is pressed?

RadChart Grouping by Month

Hi Telerik team!
Thanks I want to say thank you for the good work you are doing on the support, really appreciate that!

So, lets go to the problem I have.

I need to show in a RadChart Bars the behaivor per month the booking I have been doing in each month and sum all the booking by month.
For example I have this in my data source:

<
Date Booking
1/2/2013 2
3/2/2013 1
5/2/2013 2

1/3/2013 2
5/3/2013 6

1/4/2013 1

>

When I group on my RadChart will be this way
<
Month Booking
1 5
3 8
4 1
>

What I want to show on my Chart is for the Y the value of the Booking and for the X the month (1,2,3,4...12), if the value Booking in a month doesnt exist then would be zero.
How could I group by month(include all month even if there are not Booking for that month).
Thanks in advance!!!

RadChart Grouping and aggreate function.

Hi Telerik Team. I made a last post but no answer so I thought I didnt explain enough, so starting again.
I need to show in a Chart bars during the current year (starting from January to december) the total of the booking done per month.
For example I have on my DB table (BookingDate, BookingValue).

BookingDate BookingValue

1/1/2013 3
3/1/2013 6
13/2/2013 5
3/4/2013 3
13/4/2013 15

When I do a query to my DB I get a list of BookingObject: List<BookingObject>, this will be my ObjectDataSource.
What I need to do is to show all the booking per month in the current year. My X will be 1,2,3,4..12 months and my Y the BookingValue.
I need to show all month (1-12) even if I dont have booking for that month.

I was trying to do it but really dont have idea, how to Sum the bookingValue per month and Grouping by Month, because I have on the Object Date and not month.
If anyone can help me I would appreciate it.
Thanks in advance.

Filter Icon not visible on narrow columns

Hi
I'm having a problem with narrow columns, in that the filter icon is not visible: instead you have to faff around to try to select the teeny tiiny line that is visible.
Can anyone advise how to force the grid to display/give enough room for the filter icons?
It's my first Telerik grid, so there is nothing fancy going on behind the scenes!
Thanks!

Get Grid Content from Child Window

Im trying to get the contents of a radgrid from a child window and am having some problems. I cant access the mastertable view to get the contents... The gridPsap var picks up the element, but I cant get the master table.

Here is part of my code:

<body onload="formOnLoad();">

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script language="javascript" type="text/javascript">

function formOnLoad() {

var gridPsap = window.opener.document.getElementById("GridPsapHistory");

var gridPsapTableView = gridPsap.get_masterTableView();

var gridAli = window.opener.document.getElementById("GridAliHistory");

//window.close();

}

</script>

</telerik:RadCodeBlock>

<table>
