Context Menu

Refering to the demo:
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandmenu/defaultcs.aspx?product=grid

and using the Hierarchical data feature of RadGrid, I am trying to have context menu on the master and the details, but i wasn't able to get the selected index and the selected ID.

function CarModel_RowContextMenu(sender, eventArgs) {

var menu = $find('UC_Splitter_CarModel_List_Content_CarModel_RadContextMenu');

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

if (eventArgs.get_tableView().get_name() == "Models") {

alert('child');

//get the selected datakey value

//

}

else {

var index = eventArgs.get_itemIndexHierarchical();

var key = sender.get_masterTableView().get_dataItems()[index].getDataKeyValue("ID");

CarModelSetKeyValue(index, key);

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

please i need help in this issue urgently.

EmptyMessage remains in place if text is typed in too quickly after render or enable

I am currenlty utilizing the "EmptyMessage" property of a RadTextBox. There is also a checkbox on the page that enables the RadTextBox when clicked. If the user hovers his mouse over the RadTextBox before it is enabled, the user can then type in text and the empty message remains in place in addition to the user input. I was also able to produce this behavior on the demo site (http://demos.telerik.com/aspnet-ajax/input/examples/radtextbox/firstlook/defaultcs.aspx) if I refreshed the page with my pointer over the control and started typing before render is complete. The style also remains in the EmptyMessage style, so when you're typing it is grayed italics text. This behavior is unacceptable to my client. Any fixes/suggestions?

Thanks,
Dean

IIS 7.5 PageRequestManagerServerErrorException

I have had to move a web application from one server to a new one. My intention was to just copy the deployed application over to the new IIS structure. The app code has not changed. Both servers are Windows 2008 SP2: the old server had IIS 7 and the new server has IIS 7.5

I am now getting this error below as a javascript error.

There is a double hop involved and kerberos appears to be working. Fiddler shows no errors. Can you help me with this issue? Why would it not run in IIS 7.5?

Thanks,

How to pass data key fromItemCommand to Selecting event of ObjectDataSource

Hi all,

I need to get DataKeyValue from ItemCommand event of Radgrid and need to pass as input parameter in ObjectDataSource's Selecting event like

obj.EmpID= EmpID (runtime Value from ItemCommand)

e.InputParameters["obj"] = obj

So that the Nested DetailView should be as per that specifc row of Radgrid.

Here i am getting Key from ItemCommand, but unable to pass that key dynamically to ObjectDatasource, because both the events get call at different time interval.

Or i should try different approach.

Please help me on this regard.

RadDataPager issue

The pager appears fine in all browsers (Opera, Google Chrome, Firefox and Safari) except in Internet Explorer where it's displayed very strange e.g. next/prev buttons are invisible without background etc. etc.

Is it known bug or i am missing something. This is the code:

<telerik:RadListView ID="RadListView1" runat="server"

Customize the appearance of the toolbar

Could you please tell me or direct me to some code about customizing the appearance of the toolbar?
I don't want to use any of the predefined skins, I just want total control of the styles used.
On the same note if I am supposed to use some predefined class names, where in documentation can I find those names?
Thanks
Iulian

Locate the Delete Column at the front

Hi all!

Really need a help from all of you!
I'm using the RadGrid and using AutoGenerateDeleteColumn="true" for adding the Delete Column.
But it locates on the last column. Any ways to move it to the front?

Thanks!

Andy.

I have a little visual problem. In IE8 a Hyperlink Column that is no AlternateItem and is not Hovered
shows the Link Decoration (Underline) for the Hole Link text when only parts of the Text ist visible,
when hovered with Mouse the decoration gets fit to the columnwidth (see pictures)
