creating nodes from client side node.get_element() is null

I am trying to add nodes from client using javascript and telerik client library :

for (var nodeCount = 0; nodeCount < nodeLength; nodeCount++) {
var node = new Telerik.Web.UI.RadTreeNode();
node.set_text(MainArrayNodes[nodeStartCount].Text);
node.set_value(MainArrayNodes[nodeStartCount].Value);
var imageUrl = MainArrayNodes[nodeStartCount].ImageUrl.replace('~\\', '');
node.set_imageUrl(imageUrl);
var nodeElem = nodeElem.get_element();
selectedNode.get_nodes().add(node);
}

The nodes which i add from server / using load on demand have proper values inside of node.get_element(). But when i try to add the nodes from client side using javascript the get_element() returns null for a node. Am I missing anything ?

ClientDataString

Hi,
during migration from old combo I found that:
- here it says that ClientDataString can be used in OnClientItemsRequesting event
http://www.telerik.com/help/radcontrols/prometheus/combo_OnClientItemsRequesting.html
- same time here is says that RadComboBoxItemsRequestedEventArgs.ClientDataString was removed
http://www.telerik.com/help/radcontrols/prometheus/combochanges.html

Looks like the second statement is correct - then can you give an example using ClientDataString or Context ?
And perhaps fix documentation
Thanks
Alex

RadToolTip for row?

Hi,

I've searched the forums but haven't been able to see if this is possible.

I've got a radtooltip this is assigned to a control inside a GridTemplateColumn, which works very well. However it'd be much better if the tooltip could be applied to the entire row. Since the row doesn't have an ID I'm not sure this is possible, but would be very pleased if it is!

Thanks,
Mathew

Ajaxed Grid and Session State

If a radGrid is ajaxed, do ajaxed transactions (like deleting rows in the grid, editing rows in the grid, etc) keep the session alive? Or does keeping the session alive require postbacks?

Unable to get the dropdown selection from RADTREEVIEW inside a RADCOMBOBOX

Hi,

I'm unable to see a thread I'd posted on quite a while ago about this same problem.

We've a RADTREEVIEW inside a RADCOMBOBOX. We use the clientnodeclicking to handle the dropdown selection and follow the code mentioned in the control documentation.

However, the selection does not happen when we click for the first time. The selection triggers a partial postback which would populate a dropdownlist based on the value selected from radtreeview. The selection only happens when we re-open the radtreeview and select the same node.

function nodeClicking(sender, args) {

var senderComboBoxName = sender._uniqueId.replace('$i0$RadTreeViewCategory', '');

senderComboBoxName = senderComboBoxName.replace(

'$', '_');

senderComboBoxName = senderComboBoxName.replace(

'$', '_');

senderComboBoxName = senderComboBoxName.replace(

'$', '_');

var comboBox = $find(senderComboBoxName);

var node = args.get_node()

var nodeValue = node.get_value();

if (EndsWithString(nodeValue, "5")) {

comboBox.set_text(node.get_text());

comboBox.trackChanges();

comboBox.get_items().getItem(0).set_value(node.get_value());

comboBox.commitChanges();

comboBox.hideDropDown();

comboBox.postback();

}

}

Please help us with the problem.

Row clickable based on criteria

Hi,
I have a RadGrid with

EnablePostBackOnRowClick

="true".RadGrid may contain multiple records but only based on status field = "A" or "D" row must be clickable.If status = "P" or "S" user should not be able to click that row to go to the next grid.
I used the following event to click on the row:

protected

void PrnHistoryGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "RowClick" && e.Item is GridDataItem)

{

GridEditableItem item = (GridEditableItem)e.Item;

string reqstat = item.Cells[13].Text;

string recstat = item.Cells[11].Text;

if (reqstat == "A" || reqstat == "D")

{

e.Item.Selected =

true;

int reqno = Convert.ToInt32(item.Cells[2].Text);

LoadRejCommData(reqno, recstat);

}

else

{

if (rejcommPanel.Visible == true)

{

rejcommPanel.Visible =

false;

}

Thanks so much for your help

create thumbnail with Image Manager in Rad Editor

Hi, I have read different posts stating that image thumbnail functionality exists in image manager but I cannot find the property "AllowThumbGeneration" for some reason. I am running the latest (2011.3.1305.35) and this is all I get when clicking the properties tab.

When we have too many items in the dropdown, Chrome starts to overlap the items in the combobox.

How do you resolve this? I've attached a screenshot.
