Hi All,
I have a webdatatree with the following tree structure:
Status > Alphabet Group > Company Name > Contact Name.
The tree is set to load on demand using the following settings:
WebDataTree.InitialDataBindDepth = 1 // Alphabet Group WebDataTree.InitialExpandDepth = 0 //Status When the user adds a new company, for example "Test Corp", is it possible to expand the "T" node and load all the companies that start with "T". I have managed to expand the "T" node and select the newly added "Test Corp" node, but cannot figure out how to load all the other companies that start with "T". Thanks!
WebDataTree.InitialDataBindDepth = 1 // Alphabet Group
WebDataTree.InitialExpandDepth = 0 //Status
When the user adds a new company, for example "Test Corp", is it possible to expand the "T" node and load all the companies that start with "T".
I have managed to expand the "T" node and select the newly added "Test Corp" node, but cannot figure out how to load all the other companies that start with "T".
Thanks!
I would appreciate it if someone could help with this as this functionality is critical to the application:
Adding a new company, should expand the corresponding tree node and select the newly added company.
The tree use on-demand loading as there could be thousands of companies.
Hello csggroup,
I apologize for the delayed response. It is possible to request the items from client side with the set_expanded() method. I've attached a sample that demonstrates how to achieve this.
You can find more information on the WebDataTree's client side methods here:

Please let me know if you still need assistance with this issue and I'll be glad to help.
Please let me know if you have any other questions or concerns about this issue and I'll be glad to help you.
Hi Michael,
(Infragistics version - 11.2.20112.2086)
Thanks for the sample. I alse need to select the newly added node, but am unable to do it server side as the parent node is not expanded yet. The client side script for event Initialize is below. But, setting node.set_selected(true) causes the SelectionChanged event to be fired mysteriously when the save button is clicked next time. Please help.
var entityPath = document.getElementById('<%=uxNewEntityPathHidden.ClientID%>'); if (entityPath.value != "") { var entityPathSplit = entityPath.value.split('.'); var statusIndex = entityPathSplit[0]; var alphabetIndex = entityPathSplit[1]; var entityId = 0; if (entityPathSplit.length == 3) { entityId = entityPathSplit[2]; sender.getNode(statusIndex).get_childNode(alphabetIndex).set_expanded(true); var nodes = sender.getNode(statusIndex).get_childNode(alphabetIndex).getItems(); } else if (entityPathSplit.length == 4) { var entityIndex = entityPathSplit[2]; entityId = entityPathSplit[3]; sender.getNode(statusIndex).get_childNode(alphabetIndex).set_expanded(true); sender.getNode(statusIndex).get_childNode(alphabetIndex).get_childNode(entityIndex).set_expanded(true); var nodes = sender.getNode(statusIndex).get_childNode(alphabetIndex).get_childNode(entityIndex).getItems(); } entityPath.value = ""; for (var i = 0; i < nodes.get_length(); i++) { var node = nodes.getNode(i); if (node.get_key() == entityId) { node.set_selected(true); break; } }
}
And the other issue is,
var
nodes = sender.getNode(statusIndex).get_childNode(alphabetIndex).get_childNode(entityIndex).getItems();
nodes.get_length() returns 0 randomly. I am not able to pinpoint the cases exactly.
Thanks
