RadGrid nested items tobe displayed in rows of single RadGrid.

[Harish]

Hi Team,
                              I was exploring the Rad GridView Item for a requirement, where the gridview Items are compounded i.e. one with in other - nested to nth level(i.e. folder with in folder... folder so on ). I was looking for feature where on cliking the rowitem it should display the item nested with in it immediately below it rather in another GridviewItem or RadTabItem and the  nesteing  can be up  to nth level. Is this possible using RadGridview Item. Any suggestion/help on this would be of gr8 help.

Regards
HSR.

Hello Harish,

You may check our RadTreeListView component which I believe may suite your requirement.

Hi Pavel,
                    Thanks for your prompt response, well the requirement is specific to  GridView and cannot use TreeLIst can you please confirm if this is doable or not using GridView. To clarifiy to what I have mentioned attached is the screen shot.

Hello Harish,

Our RadTreeListView is based on RadGridView. I confirm that the layout from the screenshot attached is achievable with RadTreeListView ( not RadTreeView).

Hello,

 Just a quick follow up!

You can use the approach from this post with RadGridView to simulate treelist like structure.

Hi Pavel,
                   "I confirm that the layout from the screenshot attached is achievable with RadTreeListView"

The screenshot attached was not specific to RadTreeViewList it's a free source sample application code and has got some performance issues.

@Vlad : The link you provided is tied up with percormance issue not with what I have requested for.

Although, I had a look @ RadTreeListView it cannot be  used as it's lacking grouping functionality of items.

Hi Team,
                        I managed to find a link http://www.telerik.com/community/forums/silverlight/gridview/multilevel-hirarchy-in-radgridview.aspx

  on this forum for what I have requested, but here the data is static when binding to the Radgrid are there any samples\link which shows a way to bind data to the child dynamically.

[Pavel Pavlov]

Hello Harish ,

Please elaborate on what do you mean by adding the child dynamically ?

Pavel,
                              The link pasted has sample that have child expanded using a fixed loop I was trying to achive the same using some source (RIA\WCF) although that seems ok now, but the other issue I noticed in the sample is that when the parent node does not have any child items I still get the + sysmbol beside that, is it possible to display progarmetically hide the same.

[Pavel Pavlov]

Hi Harish,

In the context of your latest post - the GridViewRow has the IsExpandable property which controls whether to display the expander button or not . You may setting this in the RowLoaded event.

Hi Pavel,
                      I tried your suggestion to implement but couldn't find the property IsExpandable in RadGrid  RowLoaded event. Am I missing something,  Attached is the screenshot for the same.

[Pavel Pavlov]

Hello Harish ,

This event is fired for all rows  including headers and footers.  In the handler you need to check whether it is an instance of GridViewRow and if yes , you will get access to the property after casting it  to GridViewRow.
Let me know if I am unclear.
