Get count of rows for each group in grid

[Acadia]

Hello, I am struggling to figure out how to get a count of how many rows are in each of my kendo grid groups in the DataBound method. I can't find anything on this. My grid is pretty simple, and it is grouped by a single column (tran_code). 

The grouping works fine but I cannot figure out how to hide the group header row altogether if there is only 1 row in that group, otherwise show it.  All I have so far is my grouping, which is working.  I am using @html helper for the grid:

@(Html.Kendo().Grid(CarryFwdDetail)
.Name("grid")
.Group(groups => groups.Add(p => p.TranCode))

In a javascript function how can I access the group rows and count them (for each group), then hide that group header?
Any help is appreciated!
Thanks, Justin

 

Update:

I an effort to provide as much code as possible, I have been able to get to a point where I can get the count groups there are.  But I still don't know how to get the count of rows within each group and hide that groups header if it is = 1:

  .Events(e=>e.DataBound(@<text>function(e){
                    var view = this.dataSource.view();
                    if(this.dataSource.group())
                    {
                        var count = 0;
                        eachGroupItems(view, function(items, index)
                        {
                            count++
                            alert(count);
                        });
                    }
        }</text>))

function eachGroupItems(data, func) {
        for (var idx = 0, length = data.length; idx < length; idx++) {
          if (data[idx].hasSubgroups) {
            if (eachGroupItems(data[idx].items, func)) {             
              return true;
            }
          } else if (func(data[idx].items, data[idx])) {
            return true;
          }
        }
}

Update 2

I have now figured out how to get the count of rows within each grouping:

function eachGroupItems(data, func) {
        for (var i = 0, length = data.length; i < length; i++) 
        {
           alert("Data length: " + data[i].items.length);  //= number of rows in each group

            if(data[i].items.length == 1)
            {

            }
        }
}

Can anybody help me with how to hide the group header row?

 

Update 3

I figured it out.  Here is the new javascript function to replace eachGroupItems()

function eachGroupItems(data, func) {
        for (var i = 0, length = data.length; i < length; i++) 
        {
           //alert("Data length: " + data[i].items.length);  //= number of rows in each group

            if(data[i].items.length == 1)
            {
                $('#grid tbody .k-grouping-row').hide(); 
            }
        }
}

 

Hopefully this helps somebody in the future...

Hi Acadia,

This would be the approach for handling the requirements. We have a knowledgebase article demonstrating how to get all the Groups and SubGroups in Grid.
