Hi, David!

Thank you for answer.

Could you explain me one else thing  regarding WebHierarchicalDataGrid.

Using UltraWebGrid I've implemented following scenario:

User clicks on the button, the new row is added to the grid on the client side(not postbacks), actually it is empty row, and 'edit template' is opened for that newly added row.User enters values and clicks 'OK'. After that the postback is invoked.

Is it possible to do the same for WebHierarchicalDataGrid?

Could new row be added without postback?

for now the code below lead to immediate postback

grid.get_rows().add(new Array(1, 'text'));

Please explain, for now I am getting rid of  old UltraWebGrid and there are a lot of things that I have to remake.

HI Alexander,

There is no default behavior in the WDG or WHDG to have a button that adds a row. We only have the RowAdding behavior.  You call grid.get_rows().add(valArray), where grid is a ContainerGrid object (not the WHDG object).  This could be done on a button click.  On Editing Core, you will need Batch Updating on.  Batch Updating was added in 11.2.  Then an empty row would be added to the grid without posting back right away.  Then the user could enter edit mode on the new row to set the values.  You could commit with another button somewhere.

Thank you,

I've tried, it works.

Could you aslo say what event I should subscribe for to get changes on the server side, something like 'UpdateRowBatch' for UltraWebGrid.

And is there any client side method that can invoke postback,

I used to invoke postback using following method, but now I think it is obsolete

igtbl_doPostBack(gridName);

Hello Alexander,

I am following up to see if the information provided has resolved this matter.

Please let me know if I may be of further assistance with this matter.

Hello Alexander,

Seeing as how Dave has been able to answer your questions pertaining to entering a RowEditTemplate for a newly added row and having a delayed postback through batch updating I will look further into an alternate way of having a custom user control as a RowEditTemplate. I will give you a progress update by the end of the day Tuesday.

Thank you very much for help.

Could you share your thoughts on one more thing:

I want to use UserControl as RowEditingTemplate.

All works fine, the control is shown correctly but there is a problem with data binding, I've done it as shown below, but I don't like it, maybe you could suggest something better:

<ig:RowEditingTemplate >
 <ClientBindings>
   <ig:RowEditingClientBinding ColumnKey="SubRuleId"
    ControlID="subRuleTemplate" GetValueJavaScript="$get({ClientID}+'_txtSubRuleId').   
    SetValueJavaScript="$get({ClientID}+'_txtSubRuleId').value = {value};" />
</ClientBindings>
<Template>                                       
   <controls:SubRuleTempate runat="server" ID="subRuleTemplate"></controls:SubRuleTempate>                                       
</Template>
</ig:RowEditingTemplate>

SubRuleTemplate  - it is UserControl. it has asp:TextBox with  id = txtSubRuleId

I dont like the way I am getting to the edit controls located on UserControl:

$get({ClientID}+'_txtSubRuleId')

Hi,
There is no UpdateRowBatch event in the WDG.  You'll need to handle RowUpdating, RowAdding, or RowDeleting off of the editing core behavior on the server.  To commit changes, you can call grid.get_behaviors().get_editingCore().commit().  Be sure the grid is the container grid of interest, not the WHDG.
