WebDataTree - NodeTemplates and Template event handling
posted

Hi everyone,

I am using a WebDataTree to provide filtering options for a WebDataGrid on the same page. Therefore I need a couple of templates for the various types of filters that I've got (by text, DatePicker, DropDown etc).

I have created a few templates, but the controls inside the template are always shown in the second line of the node (screenshot and code snippet attached below). How can I achieve the controls being displayed in the same row as my expansion indicator.

Furthermore, in another template I have got a CheckBox included. I have read dozens of posts on the issue but none of them helped me in any way. The CheckedChanged-Event just won't fire server side. Maybe i missed out on s,th.

Any help is much appreciated,

Regards

protected void wdtFilterTree_ItemCommand(object sender, EventArgs e)
{

}

protected void cbxFilterItem_CheckedChanged(object sender, EventArgs e)
{

}

Both of these events won't fire, although I am aware that CheckBox probably is not firing ItemCommand-Event.

Below you can see the surplus space in the first line of the templated nodes:

    It seems that the broken events issue is being caused by some package update which has been applied in a recent changeset (Craig's Utility Library v3.2.0033). I'll have to see how I can get rid of that.

    Still, the empty extra line on the templates is still nagging me, so if anyone could give me a hint...
