[2.0] Ext.ux.grid.SubTableRowExpander: Foldable Rows for Grid

[jelt]

Use the following 'renderer' function of Ext.ux.SubTableRowExpander:

    renderer : function(v, p, record){
           p.cellAttr = 'rowspan="2"';
        if(record.data.subdata.length > 0) {
          return '<div class="x-grid3-row-expander"> </div>';
        } else {
          return '';
        }

Your proposal hardcode the name of the field used for "subdata"

I added Jelt's patch for the highlighting problem. I could not add BunoG's function because it didn't work and I couldn't figure out why.

cheers,

Have you tried this ? http://www.extjs.com/forum/showthrea...938#post153938
Similar to BrunoG's function, but work

[timo.nuros]

Yes, I also tried that. The problem was that all handlers (+) were gone, no matter if there was subdata or not.

[jelt]

you have 2 render function in your plugin, have you tried to replace both ?

I replace only the second and it work in my case (IE6 & FF2)

Sub data having still subrows doesn't seems to be working. can anybody help me out in solving this problem.

Thanks in advance.

[timo.nuros]

nanich, if I understood you correctly: Only one level is supported. For everything else, you have to stick with a tree. Hint to the ExtJS guys: Seems that a multi-level tree control with rows and sorting seems to be a popular request

1. Fill the grid using JSON like you would usually do.
2. Specify "reader" : "json" in the config (see above).

For anyone interested in downloading the subdata on-demand via ajax/JSON one way is to change the expand handler around line 169. I changed the function to take 4 parameters, the fourth being the rowIndex and added an Ext.Ajax.request to my server. The success method calls subtableRowExpander.updateRow(rowIndex) to immediately render the subtable. So the initial page load includes an empty array for each row's subdata attribute and when the row is expanded the actual data is requested.

hi,
it's really nice plugin and suits me requirement.
right now i am generating simple grid using DWRProxy and JsonReader.
can you please suggest me how to use your plugin with DWRProxy. Because my data is coming from Java side.Response object is like Collection object inside object.

I get some strange Errors when using the expander:
