Nikifor,

Thank you for your reply. I have seen the examples that you suggested and still don’t get how to create the TemplatedDataField for each columns on the child band when it’s dynamically loaded and the columns of the data source are dynamically created as well.

But, I was able to create the TemplatedDataField but not sure if it’s the correct way. I added an InitializeRow event to the ContainerGrid in the RowIsIandsPopulating event and then in the InitializeRow event I created a new Template and assigned it to the e.Row.Items Template. The buttons show on the child band for each column but I cannot click on any of them. They are acting as if they were ReadOnly.

void whdg1_RowIslandsPopulating(object sender, ContainerRowCancelEventArgs e)

    {

        e.Cancel = true; 

        Supplier sp = (((Infragistics.Web.UI.Framework.Data.ListNode)e.Row.DataItem)).Item as Supplier;

        sp.Products = new List<Products>(NWindClient.GetProducts(Convert.ToInt32(sp.SupplierID))); 

        ContainerGrid child = new ContainerGrid(); 

        child.Enabled = true;

        child.Level = 1;

        child.InitializeRow += new InitializeRowEventHandler(child_InitializeRow); 

        e.Row.RowIslands.Add(child);

        child.DataSource = sp.Products; 

    }

    void child_InitializeRow(object sender, RowEventArgs e)

    {

        for (int i = 0; i < e.Row.Items.Count; i++)

        {

            e.Row.Items[i].Template = new PlaceHolderTemplate(e.Row.Items[i].Text);

        }

    }

Thanks

Nikifor,

Thank you for your reply. Your example works. But, if you replace the Button with the WebImageButton it does not work.

Also, if I add a click event to the button in your example, the event is not being fired on the post back.

Thanks

Hello John,

I have investigated your issue “WebImageButton does not respond to client side interactions  when it’s in an item template in child band.”, and I have asked our engineering staff to examine this further.  To ensure that it will receive attention, I have logged this behavior in our internal tracking system with a Development ID of 123955.  The next step will be for a developer to review my investigation and confirm my findings or to offer a fix, or other resolution.

I will leave this case open and update you with any new information after the review.  You can also continue to send updates to this case at any time.

You can view the status of the development issue connected to this case by selecting the "Development Issues" tab when viewing this case on the web site. 

Please let me know if you need more information.

Nikifor,

Thank you for all your support. Let me know if you need any more information from me on this topic.

Hello John,

This behavior occurs as not a bug. When a script control is used in the template with ajax, it does render and call the start up script to initialize the client objects. So the image buttons are not fully functional. If ajax is OFF, then the whole page is rerendered, including the new init scripts. This is what needs to be done.

Hello John,

Please let me know if you have any further questions regarding this issue.
