I try to show image which is located FTP Server.

So I set ImageEditor.ImageUrl = ftp://sckpcsd:Korea%4012@krpcsdapp01/LMK/Image/2015/11/10474/7L4Q.JPG

Then when image loading, error window was happened, it says debug web page using internet explorer inside script Debugger.

If I select Yes, debugger is open.

If I select No, the image is sucessfully loading.

I think that image is located other PC, so the error window is happend.

How can I make the error message isn't happen before image loading without download image from ftp server to web server.

Editor buttons place wrong HTML code

Hi,

My first post here. I'm using the Telerik Editor that is build into the Sitecore interface, though I see from the demos that this problem applies to the default Telerik Editor also.

The problem is that the toolbar buttons don't insert the expected HTML code. For example, using the B (bold) button, inserts the HTML tag <strong> (for strong emphasis), instead of either the <b> (bold) HTML tag or better the style="font-weight:bold" attribute.

<strong> is *not* equal to displaying bold text. It is by default displayed as bold in *most* browsers, but any stylesheet can easily redefine <strong> to be displayed with other formatting, in which case the connect with the "bold" button is totally invalid.

The same goes for the I (italic) button, which doesn't insert code for italic text but an <em> for emphasized text.

Following this pattern, I would have expected the U (underline) button to insert an <a> tag, because anchors are underlined by default, but this is not the case. The U button actually inserts <span style="text-decoration: underline;">. However, in an unrelated complaint, the use of underlining in webpages is bad user experience, since many visitors will misinterpret underlined text as a hyperlink, and try to click it. An underline button should not be offered in a web editor. My suspicion is the only reason for that button being there, is because it is also available in Microsoft Word. A web page is *not* the same as a Word document, and the Telerik Editor should honor this difference, instead of trying to mimic something it is not.

controler.set_value(options);

controler.set_text(options);

var allChoicesFromCbo = controler.get_items()._array;

var selectedOptions = options.split(",");

for(i = 0; i < selectedOptions.length; i++) {

var building = selectedOptions[i].trim();

for(j = 0; j < allChoicesFromCbo.length; j++) {

var nameOfBuildingInCbo = allChoicesFromCbo[j]._properties._data.value;

if( nameOfBuildingInCbo == building) {

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:

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?

[Solved] 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

[Solved] 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?
