In a user control that contains a RadGrid, I am trying to get the header text for the column that is being sorted on. I am doing this in the prerender of the control so all the databinding should have happened already. For some reason the column does not give me the correct text. For some columns the text is changed in the needdatasource event but that should happen before my routine is called. Here is the code. Is there a better way to do this?

private void Set508SortMessage()

{

if (RadGrid1.MasterTableView.SortExpressions.Count > 0)

{

ATSortPane.Visible = AccessibilityMode;

String msg = GetString("ActionWorklist.SortCriteria.DisplayText.Text");

String sort = "";

bool firstTime = true;

foreach (GridSortExpression gse in RadGrid1.MasterTableView.SortExpressions)

{

if (!firstTime)

{

sort = sort + ",";

}

Common.Framework.SortDirection sd = GetSortDirection(gse.SortOrder);

sort = string.Format("{0}{1} {2}", sort, RadGrid1.MasterTableView.Columns.FindByDataField(gse.FieldName).HeaderText, sd);

firstTime = false;

}

lbl508Sort.Text = String.Format(msg, sort);

}

else

{

ATSortPane.Visible = false;

}

Deleting from Grid

I am trying to incorporate the following function into the 'Delete' functionality of the RadGridView:

Protected

Sub RadGridApprovers_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridApprovers.ItemCommand

If e.CommandName = "Delete" Then

'do something
End If

End Sub

My question is: does the delete happen first or whatever commands I includein this function?

thank you

Order by Resource items

I am trying to get my scheduler entries to show up in order of a resource (called PeriodID). The resource is used to store the ID of the Period selected (from the Period Table) as follows:

On Call (ID=1)
AM (ID=2)
PM (ID=3)
All Day (ID=4)

I am using SQL Datasources for binding.

I have tried using Order By PeriodID in the Datasource Select statement for the Schedule Data but that doesn't work. I then tried creating a class and using the appointmentcomparer as shown here http://www.telerik.com/community/forums/aspnet-ajax/scheduler/oder-of-entry-in-scheduler.aspx#1155620 but that adds another field to the Advanced form for manual PeriodID entry which is not what I need.

Does anyone know how to have the scheduler order entries by Resource? Thanks.

Populating Recurrence Editor?

I'm having difficulty getting the RecurrenceEditor to populate from existing values.

Here's Telerik's example on how to populate the control:
http://www.telerik.com/help/aspnet-ajax/recurrenceeditor_serverside_populating.html

I created some code to read my selection and it spits out:



Recurrence Rule Text:

DTSTART:20101124T173647Z DTEND:20000102T000000Z RRULE:FREQ=DAILY;UNTIL=20101130T000000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR

Scheduled Dates

11/24/2010 5:36:47 PM

11/25/2010 5:36:47 PM

11/26/2010 5:36:47 PM

11/29/2010 5:36:47 PM

The control's state renders fine between post backs. I then store the Recurrence Recurrence Rule Text in my database but when I try to read it back to the control later on I get nothing. None of the items are selected in the control and even the Recurrence Checkbox isn't selected? So, how do I assign this control it's values? Here's my assignment code:



protected

void Page_Load(object sender, EventArgs e)

{

this.RecurrenceEditor1.StartDate = Convert.ToDateTime("11/24/2010 5:36:47 PM");

this.RecurrenceEditor1.RecurrenceRuleText =

"DTSTART:20101124T173647Z DTEND:20000102T000000Z RRULE:FREQ=DAILY;UNTIL=20101130T000000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR"

;

}

Any help would be appreciated,

Thanks,

Scheduler

For example In RadioButtonList1_SelectedIndexChanged event, if my RadioButtonList1's selected Value = "1", show RadcomboBox (CountryName), else hide the RadComboBox. Both My RadioButtonList and ComboBox are within EditTemplate of RadGrid.

Below is my code.

<EditItemTemplate>

<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack = "true"

onselectedindexchanged="RadioButtonList1_SelectedIndexChanged"

RepeatDirection="Horizontal">

<asp:ListItem Text="Yes" Value="1"></asp:ListItem>

<asp:ListItem Text="No" Value="2"></asp:ListItem>

</asp:RadioButtonList>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="CountryName" HeaderText="Country" UniqueName="CountryName">

<ItemTemplate>

<asp:Label ID="Label3" runat="server" Text='<%# Eval("CountryName") %>'></asp:Label>

AJAX: RadGrid and User Control in RadSplitter

Hi there,



I have a page with RadSplitter which contains RadGrid and my custom user control (Footer) in two separate 

RadPanes. I enabled ajax on the grid, but I would like to update the footer with ajax as well. In code 

below I have tried inserting the footer id or the id of a panel that wraps the footer as ControlID in 

AjaxUpdateControl tag. None of them worked and they even caused that the RadGrid doesn't work properly 

(when I click on the next page button, it doesn't change the page, but loading icon is shown). 

The footer user control contains only <%Reponse.Write(DateTime.Now);%>. 



What am I missing?

Adding items to the HeaderContextMenu

I have tried several attempts to add a item to the HeaderContextMenu. I was able to add a item utilizing this method

Protected Overloads Overrides Sub OnPreRenderComplete(ByVal e As EventArgs)

Dim menu As

RadContextMenu = rgvSchedules.HeaderContextMenu

Dim item As New RadMenuItem()

item.Text = "Paste Results"

item.PostBack = True

menu.Items.Add(item)

MyBase.OnPreRenderComplete(e)

End Sub

The Postback method is because I was attempting to find a way to set a server side procedure on click. I removed the excess code from my failed attempts. There inlies the problem. I cannot for the life of me find a way to set the onclick method for the item that I added and when it is clicked I get a runtime error:

Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
