NeedDataSource not firing for NestedViewTemplate Grid initially

I have a very strange thing happening and really need some help. I am running the code below which includes a parent radgrid and a nested one but when the page first loads and I expand one of the top level grid items then the nestedviewtemplate grid (detailsGrid) doesn't have any data in it. When debugging this the detailsGrid_OnNeedDataSource event is not firing. However the parent grid (destinationCodesGrid) destinationCodesGrid_OnNeedDataSource method is firing immediately then the page renders with nothing in the nested grid. About 20 seconds later the detailsGrid_OnNeedDataSource event fires and the breakpoint hits but only after it is too late.

Here is an odd thing though if I do some other action in the grid that fires a postback first such as paging to the next page or clicking edit then after that point the destinationCodesGrid_OnNeedDataSource method fires immediately. Please advise!

Here is the code:

Can Radgrid reside in a <TD>?

Telerik Q1/2016 but this rendering behavior is the same in previous versions of Telerik.

I have RadGrid in a <TD colspan="3">. After postback the radgrid appears above the <table>.

Issue occurs with Chrome 47.0.2526.111 and IE 11 (when Edge mode is used).

It only works fine with content="IE=EmulateIE8".

VS2015 SP1, no other HTML syntax errors. Using AjaxManager.

Is there a way to remove the last column that only serve to resize correctly my grid?

Thx for your help,
have a nice day,

RadDatePIcker MinDate

Hi.

I’ve been looking at your sample for validating a Raddatepicker:-

http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/validation/defaultcs.aspx

This is my scenario:

I have a raddatepicker and the mandate=”01/01/2009” this works great of course if I want to prompt the user that the date is incorrect, however I can still submit the form.

I then put a compare validator on the page and set that to Greater than or equal to “01/01/2009”, for some reason it won’t work.

Basically I want to prevent the user from submitting the form if the date is less than “01/01/2009” am I missing something?

Thanks

Karl

RadEditor RibbonBar - ToolsFile set tool group header

HI

I'm using ToolsFile to customize the RadEditor.Tools :

.aspx

<telerik:RadEditor ID="RadEditor1" Runat="server" ToolbarMode="RibbonBar" ToolsFile="~/Editor/DefaultToolsFile.xml">
</telerik:RadEditor>

ToolsFile.xml

<tools name="Clipboard" tab="Home">
...
<tool name="Cut" text="cut" size="medium"/>
...

But how to set the group header (space char included) for tools group in ToolsFile :

<tools name="Clipboard" text="Home here" tab="Home">
...
<tool name="Cut" text="cut" size="medium"/>
...

text and header property not works, change the value of 'name' property ?

Considering your editor, but need these features:

Hi,

We have a desktop application used to edit specification documents. These docs are basically long outline-numbered lists with hierarchical list formatting. We've been wanting to move our application to the web, but haven't found an editor control with all the features we need. These are:

Support for hierarchical list numbering. I understand this is possible with your control even though it's not supported out-of-the-box.
Very solid import and export for RTF and DOCX, including support for those outline lists. We are willing to use a third-party library to convert the RadEditor's HTML to DOCX or RTF, if that's what it takes. We just want to know if it is possible at all. Users will be doing a LOT of this with our application.
Track changes, including preserving track changes in imported/exported documents. Users will work a lot of with existing documents, and will want to bring in documents that already have tracked changes in them. I understand you support tracked changes (very nice!) Just want to make sure the import/export is solid as well.
Paragraph identification. We need to track a paragraph throughout a document's lifecycle. We thought maybe a bookmark or maybe an anchor could be used for this.

What do you say--could our requirements be fulfilled with your product, or are we stuck in the Desktop world for a while longer?

Best Regards,

David

Wizard resert on Button Click

Good Day

i am trying out the Telerik with a Trial Version, i am looking for a wizard control, and i came across telerik Wizard. i have a Wizard that creates the steps dynamically and add the usercontrols dynamically and it works perfectly.

in the user control that is shown on the Steps , there is a button.

1) i cannot hit the breakpoints on the user control

2) if i click the button on the Step, the Wizard gets reset , all the dynamically created steps are removed i will have an empty wizard

Thanks
