[CLOSED] How to pass extra parameter on to TreeLoader

[mxp]

1. How do I pass extra parameters to TreeLoaderhandler?
2. Is possible to add EventMask to TreeLoader?


Thank you.

<ext:TreeGrid ID="TreeGrid1" runat="server" Title="Current Position" AutoWidth="true"
AutoHeight="true" EnableDD="true">

<Loader>
    <ext:TreeLoader RequestMethod="GET" DataUrl="TreeLoader.ashx" PreloadChildren="true">
    </ext:TreeLoader>
</Loader>


<Columns>
    <ext:TreeGridColumn Header="Account" Width="200" DataIndex="text" />
    <ext:TreeGridColumn Header="Currency" Width="200" DataIndex="text" />

Hi,

How do I pass extra parameters to TreeLoaderhandler?
Use BaseParams of a TreeLoader
https://examples1.ext.net/#/TreePane...ageTreeLoader/




Is possible to add EventMask to TreeLoader?
Node shows loading animation during request already. But if you need to mask another place then use BeforeLoad and Load listeners of the TreeLoader. For example,


1.Mask TreePanel

<BeforeLoad Handler="TreePanel1.body.mask('Loading...', 'x-mask-loading');"/>

2. Unmask

<Load Handler="TreePanel1.body.unmask();"/>

How do get information from current node that trigger expand i.e. AsyncTreeNode.CustomAttributes in "???"

<ext:PageTreeLoader OnNodeLoad="NodeLoad">


<BaseParams>


<ext:Parameter Name="parm1" Value="???" Mode="Raw" />


</BaseParams>


</ext:PageTreeLoader>

Thanks

Hi,

Value="node.text"

Value="node.attributes.myattr"

Thanks,

But node always refered to the last node on the treegrid not the current node click and cause the last node the treegrid to expand. May be I missed somthing?

[Vladimir]

Hi,

No, it refers on node which requests the children (when you expand the async node it initiate request to load children, that node will be availbale through 'node' variable)

Attached code describe issue. Click on Acct1 and Acct2 will expand.

Thanks,

Hi,

Acct1 and Acct2 nodes have the same id - 1

asyncNode.NodeID = (Convert.ToInt32(e.NodeID) + 1).ToString();

id must be unique.

Thank you, works.

Sorry to keep bother you,

Why the header and column is not size properly after the load?

Is this fixed in Ext.Net (http://www.extjs.com/forum/showthread.php?t=92864)?

Thanks
