Hi
I am new to telerik controls.I used radscheduler with recurrence but I am not able to get recurrence rule in server side while inserting a appointment in database.
An appointment is inserted with out the recurrence.I am binding the scheduler to a datasource.

<telerik:RadScheduler ID="RadScheduler1" runat="server"

DataDescriptionField="CH_DESC" DataEndField="CH_TOTIME"

DataKeyField="CH_BOOKID"

DataStartField="CH_FROMTIME" DataSubjectField="CH_BOOKSUBJECT"

OnAppointmentDelete="RadScheduler1_AppointmentDelete"

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate"

OnAppointmentInsert="RadScheduler1_AppointmentInsert"

OnAppointmentCreated="RadScheduler1_AppointmentCreated"

OnAppointmentDataBound="RadScheduler1_AppointmentDataBound"

MinutesPerRow="15" TimeLabelRowSpan="1"

Skin="Windows7" GroupBy="Hall" Height="400px"

DayStartTime="09:00:00" DayEndTime="19:00:00"

WorkDayStartTime="09:00:00" WorkDayEndTime="19:00:00"

EnableDescriptionField="True" ShowAllDayRow="False" AdvancedForm-Modal="true"

StartInsertingInAdvancedForm="True" AdvancedForm-Enabled="true" AdvancedForm-EnableCustomAttributeEditing="true"

DataRecurrenceParentKeyField="CH_RECPID" DataRecurrenceField="CH_REC" EnableRecurrenceSupport="true">

<AdvancedForm EnableCustomAttributeEditing="true"/>

<AppointmentTemplate>

<div class="rsCategoryViolet">

<br />

Subject:<%# Eval("Subject")%><br

/>Time:<%#Convert.ToDateTime(Eval("Start")).ToShortTimeString()%>- <%#Convert.ToDateTime(Eval("End")).ToShortTimeString()%>  <

br />

</div>

</AppointmentTemplate>

</telerik:RadScheduler>

</asp:Panel>

By default CH_RECPID,CH_REC is set to empty string.
Please tell me a solution for this.
thanks in advance

ControlsToSkip and Textbox

Hi friends,

<telerik:RadFormDecorator ID="id runat="server" ControlsToSkip="Textbox"></telerik:RadFormDecorator>

Seems not to be working for textboxes, instead, the below serves the purpose.

<telerik:RadFormDecorator ID="id runat="server" ControlsToSkip="Textarea"></telerik:RadFormDecorator>

Am I missing something ?

Thanks,

Obtain parent item value from radgrid hierarchy

I have a three level radgrid hierarchy and I have trouble retrieving the value for one of my columns within the 2nd level of my radgrid. I have this code which retrieves the key for the radgrid parent as shown below:

parentItem.OwnerTableView.DataKeyValues(parentItem.ItemIndex)("ID").ToString

But I don't need the value of the key, instead I need the value of the 2nd column in one of the hierarchy levels in my radgrid.

How could I retrieve that value instead of the key....?

In the process of updating some functionality I refactored out a user control (below).

}

As is, a javascript TypeError: Telerik.Web.UI.RadScheduler is undefined appears, the scheduler renders and works in every aspect except that the appointments' subjects don't appear. Removing both resource types (not just one) displays the subjects. Moving the code back to the parent page just throws slightly different javascript errors--c[0] or n is undefined; usually related to some sorting thing--but visually makes no change. It seems independent of all other properties of the radscheduler. I've looked at similar issues that suggested the web.config needed a handler, but mine's setup correctly. Another suspected the grouping, but that's not the issue here.
An appointment template ignores the data; it'll display hard-coded content. The data is accessible in the code-behind, and I've used it to manipulate the Tooltip which works fine, but the appointment subject refuses to display.

From what I've gathered, it's not connecting the scripts RadScheduler needs to run, but the fix they recommended (EnableEmbeddedScripts) didn't work for me.

Sorting data in PivotGrid

Hi,

Is it possible to sort aggregateField in Server-side.

I tried to add PivotGridSortExpression but that doesn't work.

var aggregateField = new PivotGridAggregateField();

rpgCA.Fields.Add(aggregateField);

aggregateField.DataField = "CA";

aggregateField.UniqueName = "CA";

aggregateField.DataFormatString = "{0:C0}";

aggregateField.TotalFormatString = "{0:C0}";

aggregateField.GrandTotalAggregateFormatString="{0:C0}";

aggregateField.TotalFormatString = "{0:C0}";

rpgCA.Rebind();

Thank you for your reply

Page Next and Previous not firing ItemCommand until after postback

Hello!

We've implemented custom paging but the next and previous button only work after a postback has already happened. For example, I load the grid, click next and nothing happens. But if I page to a page number, and then click the next button, it works.

<telerik:RadGrid ID="RadGridTicketDetails" runat="server" ActiveItemStyle-BackColor="Green"

HeaderStyle-BackColor="#00597A" Skin="Metro" ShowGroupPanel="True" EnableLinqExpressions="False"

OnInit="RadGridTicketDetails_OnInit" OnNeedDataSource="RadGridTicketDetails_OnNeedDataSource"

Width="100%" CellSpacing="0" GridLines="None" OnItemCommand="RadGridTicketDetails_OnItemCommand">

<MasterTableView TableLayout="Fixed" AllowPaging="true" AllowCustomPaging="true"

AllowSorting="true" AllowFilteringByColumn="true" GroupsDefaultExpanded="true"

PageSize="10" AutoGenerateColumns="false" EnableViewState="true">

<PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="True">

</PagerStyle>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

<HeaderStyle CssClass="RadGridHeader"></HeaderStyle>

<FooterStyle CssClass="FooterStyle"></FooterStyle>

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column" Visible="True">

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column" Visible="True">

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="Id" UniqueName="Id" HeaderText="#"

AutoPostBackOnFilter="false" />

<telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name"

AutoPostBackOnFilter="false" Display="false" />

</Columns>

</MasterTableView>

<GroupingSettings ShowUnGroupButton="true" CaseSensitive="false" />

<ClientSettings EnableRowHoverStyle="true" AllowDragToGroup="True" EnablePostBackOnRowClick="false"

AllowGroupExpandCollapse="True" AllowColumnsReorder="true">

<Selecting AllowRowSelect="True" />

</ClientSettings>

<HeaderStyle BackColor="#00597A" />

<ActiveItemStyle BackColor="Green" />

<PagerStyle AlwaysVisible="True" />

<FilterMenu EnableImageSprites="False">

</FilterMenu>

</telerik:RadGrid>

On the first visit, the HTML of the button is

<input type="submit" class="rgPageNext" title="Next Page" value=" " name="ctl00$ctl23$g_b6bc5c7c_8c99_4d92_93de_27af5146203d$ctl00$RadGridTicketDetails$ctl00$ctl03$ctl01$ctl28">

But on the second load after an action (postback) the output is

<input type="button" class="rgPageNext" title="Next Page" onclick=

"javascript:__doPostBack('ctl00$ctl23$g_b6bc5c7c_8c99_4d92_93de_27af5146203d$ctl00$RadGridTicketDetails$ctl00$ctl03$ctl01$ctl28','')"

value=" " name="ctl00$ctl23$g_b6bc5c7c_8c99_4d92_93de_27af5146203d$ctl00$RadGridTicketDetails$ctl00$ctl03$ctl01$ctl28">

which fires the itemcommand as it should.

Can anyone help?

RaisePostBackEvent not always firing

Hi, I have a very annoying problem with my app and cant find any similar topic. I have a Page with a RadAjaxPanel containing 2 RadPanes (1 for Menu and 1 for Page content). The Page also have a second RadAjaxPanel containing some RadComboBoxes. On some predefined conditions, selecting an item in the mentionned RadComboBoxes should trigger a postback refresh on the Page content pane mentioned. Everything works but approx 10% of the time, the postback seems not be firing. When it happens I simply select something else in my RadComboBoxes and then it works. Cant find any pattern to replicate as it seems totally random.

Panel with comboboxes

<telerik:RadAjaxPanel ID="RadAjaxPanel2" runat="server">

<div class="EnterpriseNodes1">

<telerik:RadComboBox ID="RadComboBox1" runat="server" Skin="WebBlue" MarkFirstMatch="true" Visible="false" AllowCustomText="true" Filter="StartsWith" CssClass="combo1" NoWrap="True" OnItemDataBound="RadComboBox1_ItemDataBound" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_OnSelectedIndexChanged" OnClientDropDownOpened="ShowEmptyMessage" OnClientDropDownClosed="HideEmptyMessage" >

<telerik:RadPane ID="RadPane2" runat="server" CssClass="ContentPane" ContentUrl="Test.aspx">

</telerik:RadPane>

</telerik:RadSplitter>

</telerik:RadAjaxPanel>

The function doing the magic is this one:

public void RefreshPanel(ref RadAjaxPanel rapPanel, ref RadPane rpPane, string strUrl, string strQuerystring)

{

rpPane.ContentUrl = strUrl + strQuerystring;

WriteLog(rpPane.ContentUrl); //logging to check if code is called with right parameters

rapPanel.RaisePostBackEvent(null);

}

Everytime I check my log file (when refresh seemed to not occur), RaisePostBackEvent was called and ContentUrl of rpPane has the right value.

Is there a better way to do this, or any other property of rpPane/rapPanel I can check to find what could be wrong? Please help, this is killing me.

UPDATE: Can it be because im running the demo of the control (and sometimes get the "Thank you for using the Trial Version of RadControls for ASP.NET AJAX ..." message) and affect the post backs?

TIA

How to add Filter in Header section

Greetings,

Is it possible to add the Grid Filter in the Header Section of the Grid instead of below the header in its own row?

IF that is not possible, is it possible to create a filter exactly like the one used in the Filter Row section? A filer that has the button with all the filtering options (Contains, Equals, Not Equal, etc....)

Or is it possible to eliminate the Header all together and just put the header in the Filter Section ?

How to add more label to the column in HtmlChart?

Hi,

Please take a look at the attaced pic, I can only display the percentage value (which is from the column "AverageScore" in the DataTable) on the column bar. I would like to add in some description label for each column (which is from the column "Description" in the same DataTable).

Is it possible to do it with HTMLChart? If not, What's about RadChart, is it possible to do so?

Thanks
