ASPxTreeList elishalevi [Israel] 14-Sep-2009 14:36:49

I am using DataCellTemplate to customize each cell of the treelist.
I can add controls to this cell like gridview, buttons ...ext.
But , When i try to add aspxTreeList control to a cell - i see only the headers - where i can click and activate sort , But cant see any rows, nodes of the tree.
I create this tree at runtime , and append nodes manualy - when i test the code on a page it works fine.
the problem is only when i try to create the treelist inside a cell of the main treelist.

any suggestions?

Are the checkboxes on the tree side part tri-state and automatically calculated?

If not, then this control doesn't add much to the armoury......

ASPxTextBox not working with ASPxTreeList. r_beacroft [United Kingdom] 31-Jul-2008 10:59:02

Add an ASPxTextBox to a DataCellTemplate - get a javascript error - points to 2nd line of code below...

var dxo = new ASPxClientTextBox('ctl00_ContentPlaceHolder1_assetAllocationTreeListViewer_tlAssetAllocationViewer_tDC11_37-837_ASPxTextBox1');

window.ctl00_ContentPlaceHolder1_assetAllocationTreeListViewer_tlAssetAllocationViewer_tDC11_37-837_ASPxTextBox1 = dxo;

dxo.uniqueID = 'ctl00$ContentPlaceHolder1$assetAllocationTreeListViewer$tlAssetAllocationViewer$tDC11_37-837$ASPxTextBox1';

dxo.widthCorrectionRequired = true;

Am currently evaluating ASPTreeList - tried to use forum on DevExpress website and disappointed to say unable to submit a query. Always get back "Your question has already been answered" without even asking a question. This makes me feel like I should stay clear of DevExpress products.

Willing to persevere a little longer though, solely because of time spent trying to get control to do what we want.

I am using the virtual mode to draw each level. Our data is structured in a recursive way. This is raising the duplicate node key error, even though the nodes are at different levels.

It seems that each node, irrelevant of depth needs to be unique! Is that correct? And, although I have tried various things to get the data unique, I am unable to do this as I cant seem to work out which level is being rendered, since every level is redrawn. And the NodeChanging event does not fire until the VirtualModeCreateChildren has rendered.

Please can you let me know if there is a way of arching this. I really like this control and intend to buy this product if this issue can be resolved.

Regards,
Rik
