RadGrid - Collapsing or expanding a group removes the entered but non-saved data

Hi, I have a RadGrid with collapsed rows. If I expand group 1 and modify data, and then expand group 2 to enter more data, the data in group1 is gone. Is this a bug or am I doing something wrong?

Issues with Multiple RadAjaxPanel

I am writing this simple page with two RadAjaxPanel as:

On the server side, I have written to simply visible the panels as:

protected void Unnamed_Click(object sender, EventArgs e)
{
panel1.Visible = false;
panel2.Visible = true;
}

protected void Unnamed_Click1(object sender, EventArgs e)
{
panel1.Visible = true;
panel2.Visible = false;
}

Issue is, when I click first button that makes panel 2 visible and panel 1 invisible. But, when I click second button panel 2 is getting invisible but panel1 is not getting visible again.

Attributes

Hi

I need to add some attributes to the data source so that when my JS function on the OnRequestEnd event is called it can interrogate the attributes.

Most controls have the attributes but I cant seem to find anything for the ClientDataSource.

Any ideas?

Regards

Jon

RadGrid Frozen Columns Problem on Safari Browser in Apple IPAD

I am using RadGrid with static headers and frozen column for bulk update of data exactly as provided by your LiveDemo: Grid-Dataediting-ClientEditBatchUpdates.

The Rad Grid is working as expected for all browsers (IE on windows, Safari on windows, Firefox on windows) , but we are facing problems on horizontal scroll in safari on IPad.

Problem : The horizontal scroll on the grid does not move the headers, but it moves the data content. The expected behavior : on horizontal scroll, the headers and data should move on scroll.

Remember we have frozen columns on the grid.

This behavior is not working only on mobile Safari . The control works as expected on IE - windows, Safari - windows, Firefox - windows.

The only difference between the livedemo Grid-Dataediting-ClientEditBatchUpdates and my code is I have added frozen column ( first 2) on the grid.

How to pass paramenter on RadSchedule ResourcePopulationMode=ClientSide

I using webservice popolate data on RadSchedule. But when build load Resourece, I want to pass some parameter to load list Resource in MySchedulerProvider. How to call and code example??? When I using using:

private MySchedulerInfo _customParameter = new MySchedulerInfo();

private IDictionary<int, Resource> _subjectId;

private IDictionary<int, Resource> SubjectId
{
get
{
if (_subjectId == null)
{
_subjectId = new Dictionary<int, Resource>();
foreach (Resource subjectId in LoadSubjectId(_customParameter.ClassId))
{
_subjectId.Add((int)subjectId.Key, subjectId);
}
}

return _subjectId;
}
}

public override IEnumerable<Appointment> GetAppointments(ISchedulerInfo shedulerInfo)
{
List<Appointment> appointments = new List<Appointment>();

MySchedulerInfo myInfo = shedulerInfo as MySchedulerInfo;

if(myInfo != null)
{
_customParameter = myInfo;

using (DbConnection conn = OpenConnection())
{
DbCommand cmd = DbFactory.CreateCommand();

if (cmd != null)
{
cmd.Connection = conn;
cmd.CommandText = "SELECT [Id],[Class_Id],[School_Id],[Subject],[Description],[Begin_Date],[End_Date],[Recurrent_Rule],[Recurrence_Parent_Key],[Subject_Id],[Reminder] FROM [Class_Schedule] WHERE [Class_Id]=@ClassId;";

apt.End = DateTime.SpecifyKind(Convert.ToDateTime(reader["End_Date"]), DateTimeKind.Utc);
apt.RecurrenceRule = Convert.ToString(reader["Recurrent_Rule"]);
apt.RecurrenceParentID = reader["Recurrence_Parent_Key"] == DBNull.Value ? null : reader["Recurrence_Parent_Key"];

if (reader["Reminder"] != DBNull.Value)
{
IList<Reminder> reminders = Reminder.TryParse(Convert.ToString(reader["Reminder"]));
if (reminders != null)
{
apt.Reminders.AddRange(reminders);
}

if (apt.RecurrenceParentID != null)
{
apt.RecurrenceState = RecurrenceState.Exception;

Binding ScatterLineSeries Directly to SQLDataSource

Hey everyone,

Thanks for reading. I have a RadHtmlChart and a SqlDataSource. The SqlDataSource is attached to a Stored Procedure that returns 2 columns: a date, and an amount.

I simply want to plot the dates along the X and the amount along the Y, however I'm having some difficulty achieving this. Please see the code below:

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

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="RadAjaxLoadingPanel1">

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" DataSourceID="sdsDeclineReport" Width="600px" Height="400px">

<PlotArea>

<Series>

<telerik:ScatterLineSeries DataFieldX="date" DataFieldY="amount">

<TooltipsAppearance Color="White" DataFormatString="{0:MM/dd}"></TooltipsAppearance>

<LabelsAppearance Visible="false">

</LabelsAppearance>

</telerik:ScatterLineSeries>

</Series>

</PlotArea>

<Legend>

<Appearance Visible="false"></Appearance>

</Legend>

<ChartTitle Text="Declines"></ChartTitle>

</telerik:RadHtmlChart>

</telerik:RadAjaxPanel>

The result looks like this:

http://i.imgur.com/TGtKTNxl.png

The "Amount" column ranges from 0-20, and the dates go from 2016-01-01 to 2017-01-01. Can someone point me in the right direction here in regards to the lack of any data, as well as where I went wrong with the axes? Thanks

Autocompletion behaves differently for a couple of clients.

Hello Telerik team,

we are using the RadAutocompleteBox in our .aspx-page. In the Page_Load-function we are binding the data like this:

protected void Page_Load(object sender, EventArgs e)

{

var siteUrl = SPContext.Current.Web.Url;

SPSecurity.RunWithElevatedPrivileges(delegate()

{

using(var site = new SPSite(siteUrl))

{

using(var web = site.OpenWeb())

{

var dbaccess = new DBAccess(web);

radComboPlz.DataSource = dbaccess.GetPlzListeDataTable();

radComboPlz.DataBind();

}

});

}

With our control we want to enable the user to search for zip codes. This is how the control looks like:

<telerik:RadAutoCompleteBox RenderMode="Lightweight" runat="server" ID="radComboPlz" EmptyMessage="" Skin="Windows7"

DataTextField="PlzOrt" InputType="Text" MinFilterLength="2" AutoPostBack="False" Filter="StartsWith">

<TextSettings SelectionMode="Single" />

</telerik:RadAutoCompleteBox>

Now let's assume we have some zip codes looking like this, "509511", "509678", "509144"....

We also have some zip codes looking like this, "501223", "501789", "501445"...

The main difference is that some have 509 for the first three digits the others begin with 501.

Now the problem that we encounter is somehow hard to reproduce because only a couple of users are experiencing it. For example if I type 509 in most cases the suggestions are looking as supposed, namely showing entries starting with 509 (see attached file "509.png"). While for some clients the autocompletion seems to stop after "50" and therefor returns entries staring with "501" (see attached File "501.png").

We are using the latest version of IE but also were able to reproduce the issue using other browsers (FireFox and Chrome). Is this a know issue, if so how to handle it? Might we be missing some parameter in the Control?

Regrads and thanks in advance!

docx file conversion issue

Hello,

We are providing .docx file to the RadEditor.
It does not convert this files as per their original formatting.

Following are some of the points we have noticed.

1. Accepts only .DOCX and .RTF documents. It does not accept .DOC files.

2. When we import .DOCX, the formatting get disturbed.
a) Header and footer from the original file is removed.
b) Overall alignments are not as per the original document provided.
c) Table boarder in the document goes missing in some case.
d) Images goes missing in some cases.
Over all, after loading the file in the viewer, it does not look as per the original document.

Thanks.
