We’re evaluating using the Gantt component for a very large
project; we did not use it before, but extremely familiar with the other
components. It seems this one is missing a few things from the smart Tag, like
data source selection and maybe one day a designer for it. We are a little lost
inside of it and for some crazy reason could not get the examples to work in
VB. Would it be possible to help us with a very simple example that builds the
entire chart from code behind and uses Objects and not a direct connection to
db or a SQL dataset. If possible, please use a FOR loop to insert the Tasks and
relationships. Thank you for the help.

[Solved] RadDropdownTree.Selected Value cannot be assigned to

Hi,

I'm trying to pre-check all checkboxes with a RadDropdownTree control after it has been bound to (as per the sample code here) but I am getting a 'RadDropDownTree.SelectedValue' cannot be assigned to -- it is read only' error.

I've had a look about online to check for a versioning issue but couldn't see anything - I'm currently using release 2013.1.403.35, is this the issue?

Thanks,
Allan

AjaxToolKit 15.1 and Telerik Controls

Hi,

We've discovered compatibility issues with the new version of AjaxToolKit (15.1)
And your Controls.

When putting some of the controls (i.e RadDatePicker) in a page that uses the
New AjaxToolKit, an error occurred (attached a screenshot).

Please note that this is the new version AjaxToolKit that uses the regular
ScriptManager from Microsoft (no longer ToolkitScriptManager) so all
the documenations you have on this are irrelevant for the new version.

Any suggestions ?

Stepping

Hi,

I am trying various methods for adjusting the minor grid line step value and each one fails. What is the current JS that I could use to change the minorgridline step value?

Sample code that I have been trying is shown below.

Regards

Jon

var kendoWidget = $find("<%=uxRadHtmlChart.ClientID%>").get_kendoWidget();

kendoWidget._plotArea.valueAxis.options.minorGridLines.step = 10;

kendoWidget._plotArea.valueAxis.options.minorUnit = 10;

kendoWidget.redraw();

OnClientSelectedIndexChanging event not fired in Javascript

Hi I have a RadComboBox in my app where i intend to use OnClientIndexChanging event to cancel the changing of the values based on some specific conditions, however the event is not getting fired in client side JS code

<telerik:RadComboBox ID="cbStyleSize" style="width:100%" EmptyMessage="--Select Style Size--" runat="server" RenderMode="Native" DataTextField="Name" DataValueField="ID" OnClientSelectedIndexChanging="OnChanging_Style" OnClientSelectedIndexChanged="OnChanged_Style">

</telerik:RadComboBox>

As you can see i have both OnClientSelectedIndexChanged and OnClientSelectedIndexChanging events , however only OnClientSelectedIndexChanged event is getting fired in JS but not the Changing event.

01.function OnChanged_Style(sender, eventArgs) {

02. var item = eventArgs.get_item();

03. var item_text = item.get_text();

04. var itemValue = item.get_value();

05.

06. var ret = ExtractComboValues(itemValue);

07.

08. if (ret) {

09. setData({

10. sID: ret.sID,

11. Name: item_text,

12. fPrice: ret.price

13. });

14.

16. }

17.}

18.

19.function OnChanging_Style(sender, eventArgs) {

20. var item = eventArgs.get_item();

21. var item_text = item.get_text();

22. var itemValue = item.get_value();

23.

24. var ret = ExtractComboValues(itemValue);

25. var targetID = ret.sID;

26.

27. var errFunc = function(e) { e.set_cancel(true); }

28. var succFunc = function(e) { e.set_cancel(false);}

29.

30. if (ret) {

31. VerifySelection(targetID, succFunc, eventArgs, errFunc, eventArgs);

32. }

33.}

Just on a side note , the OnChanging_Style JS function , makes an AJAX call through VerifySelection function and based on the result of that function set_cancel(true) is being called. .Do you think its legal that an AJAX function whenever returns can revert back the ComboBox fired event ?
