Provider problems

Hi there,
have set up a Provider for the Scheduler to enable multiple resources…
This part is working well – but am getting lots of error with my recurring appointments (normal ones are fine). Have modelled my code from the example in the DbScheduleProvider in the Demo project.
If I try to delete a recurring (either series/individual) I get:

Cannot locate the parent of appointment with ID = '15'. Ensure that the parent appointment with ID = '' exists and is loaded.
[InvalidOperationException: Cannot locate the parent of appointment with ID = '15'. Ensure that the parent appointment with ID = '' exists and is loaded.]

If I move a recurring appointment I get:

Really appreciate any help I can get!

That is my code..

Scenario:

-I have 12 records ( 0.12Records.JPG)

-I try to filter (1.Search.JPG) The filter is fine.

-Then I click Search button to rebind grid's datasource (2.Search.JPG)

-The right click filter on header , the text is cleared. But, the records not showing all records. I try to type something, the filter is not working.

-After I click Search Button (again) the filter is fine again.

What inside button search is:

private void BindGrid()

{

try

{

sessUserCollection = null;

rgridUserList.Rebind();

}

catch (Exception Ex)

{

throw Ex;

}

So, the problem is when I click once the search button (rebind grid) the filter is crippled.

I need to click it twice, so the database hitted twice.

Any ways to solve this problem?
Am I missing something?

Cannot sort RadDropDownList within EditItemTemplate.

Hello, thanks for looking at my question. I have a popup Add Record window, one of the fields to select is a RadDropDownList that is populated by the Department ID column from the database. The items in the list are not sorted and I would like them sorted in order for the user to find he needed ID faster.

The RadDropDownList is within an EditItemTemplate that is within a GridTemplateColumn.

<telerik:GridTemplateColumn HeaderText="DepartmentID" ItemStyle-Width="240px">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem, "DepartmentID")%>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadDropDownList runat="server" ID="RadDropDownList1" DataTextField="DepartmentID"
DataValueField="DepartmentID" DataSourceID="SqlDataSource1" SelectedValue='<%#Bind("DepartmentID")%>'>
</telerik:RadDropDownList>
</EditItemTemplate>
</telerik:GridTemplateColumn>

I have tried AllowSorting, SortExpression on the RadDropDownList and they did not work.

What am I missing in my code?

Thank you, Dale

Partially Installed?

I used the new Telerik control panel to update my ASP.NET Ajax, Reporting and JustCode. There were no error messages shown, but if I click on ASP.NET Ajax or Reporting, it shows a status of "Partially Installed". I tried to repair both installs, but still have the same message. What the heck does it mean and how do I fix it?

Radmenu in RadAjaxPanel

Hi there,

I'm currently using a Radmenu in a RadAjaxPanel. On a Itemclick in the radmenu i clear the multipage and add a new one based on the value of the radmenuitem, the radmenu however stays expanded after the refresh. If i remove the above RadAjaxPanel the radmenu doesn't stay expanded, with the radajaxpanel it does. How can I solve this?

Kind Regards,

Menu

Expand/Collapse Icon Not Changing with set_expanded()

Using the latest SP of 2015.2.

I have a Hierarchy RadGrid with the following options set:

HierarchyLoadMode="Client"

and

Then in Javascript:

function expandCollapseRow(sender, args)

{

var item = args.get_item();

item.set_expanded(!item.get_expanded());

}

This works great - but if I don't click on the Expand/Collapse Icon directly - the icon does not change. I think this may be a bug with set_expanded()

Drag and Drop not working on IE11

Hello everyone, drag and drop is not working on Internet Explorer 11, but it's working on Chrome 46.

On a aspx page, with 3 rad async upload controls, when I drag and drop the image, Explorer just show the image.

The online demo works on IE11 but I believe it's using a Telerik newer version.

http://demos.telerik.com/aspnet-ajax/asyncupload/examples/draganddrop/defaultvb.aspx?show-source=true

I'm using the Telerik Version Q2 2013 SP1.

Thanks in advanced.

First call of RadLightBox does not work

Hello Telerik-Team,

i have a RadLightBox with a ItemTemplate and a RadGrid with an asp:LinkButton, where i open the lightbox.

Open the Lightbox is without any problems. I can change the Textbox Value in the RadLightBox Itemtemplate in PreRender.

But the problem is, in the first call is the Textbox in RadLightbox always empty. The calls after are working without any problems.

Any Ideas?

Thanks,

Nick

$get('<%= HiddenField1.ClientID %>').value = recordId;

var lightBox1 = $find('<%= RadLightBox1.ClientID %>');

lightBox1.show();
