Hi David,

Here's a sample.

Moreover if you could explain me how to set the default value of parentID to (null) for root creation record, it could be fine.

I hope that you'll help me, cause last time you asked me a sample, i uploaded it and i'll still waiting.
So, please have a look to all my recents posts (since june) in the asp.net forums :)

Regards,

Gregory

Oupsss..

I didn't pay enough attention to the result... If a row has child record, there's two rowisland displayed...

Is there a way to hide the second one ? I tried to set it to visible=false, during the RowIslandsPopulated event with no luck....

Did you have AutoGenerateBands="false" on the WHDG?

-Dave

no. I just add in the sample i send you :

<Bands><ig:Band IsSelfReference="True" Key="ChildBand_0">
<Columns><ig:BoundDataField DataFieldName="ID" Key="ID"><Header Text="ID" /></ig:BoundDataField><ig:BoundDataField DataFieldName="Name" Key="Name"><Header Text="Name" /></ig:BoundDataField><ig:BoundDataField DataFieldName="ParentID" Key="ParentID"><Header Text="ParentID" /></ig:BoundDataField></Columns><Behaviors><ig:EditingCore EnableInheritance="True"><Behaviors><ig:CellEditing EnableInheritance="True"><ColumnSettings><ig:EditingColumnSetting ColumnKey="ParentID" ReadOnly="True" /><ig:EditingColumnSetting ColumnKey="ID" ReadOnly="True" /></ColumnSettings></ig:CellEditing><ig:RowAdding EnableInheritance="True"><ColumnSettings><ig:RowAddingColumnSetting ColumnKey="ID" ReadOnly="True" /><ig:RowAddingColumnSetting ColumnKey="ParentID" ReadOnly="True" /></ColumnSettings> </ig:RowAdding> </Behaviors></ig:EditingCore>
<ig:RowSelectors></ig:RowSelectors></Behaviors></ig:Band></Bands>

So could you set AutoGenerateBands="false" on the top WHDG.  I had it set and only had one child in my sample.

-Dave

Sorry, autogeneratebands was false in the sample i sent you.
Finally, i add in the rowislandpopulated this :

if (e.Row.RowIslands.Count > 1)
e.Row.RowIslands.RemoveAt(1);

And it works.

Could you help me with my others issues ?

Hello Gregory,

I see that you created support ticket CAS-69700-13Q3Y3 for this issue.
We will continue our discussion through the support ticket

Hi Dave,

After more tests, your purposed solution is not sufficient.

Cause after adding a row with the addrow on the added band (used for items that have no child), I have no expandable icon and so I'm not able to add a child row to the newly created row.

Have you another trick ?

Regards,

Gregory.

It don't works.

Could you provide me a working sample ?

In the code behind, in Page Load, do the following.

this.WHDG1.Bands[0].RowAdded += ...

You need to add the event to the band that the child is created from.  Or you could handle row island created and add it to the ContainerGrid there.
