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

Hi Gregory,

I'm looking into why this set up doesn't work.  When I got it to work on my end, I actually defined a child band that had the same columns as the parent and set IsSelfReference="true" on that.  Then I got what I wanted.  Would this be acceptable in the meantime?

This workaround works...but I hope that will be corrected in the next release.

Thank you for your help, i don't know how you find this tricky trick !!

Your components are really powerful, but too powerful to be tested in all situations and to have good documentation and samples.

Could you help me for my other issues ?

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>

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.
