    So I get the following error message when using jqxexpander. I am calling the expander for each row (click event) presented in the jqxGrid. It seems to work the first couple of times but then I see this error message upon repeated attempts to invoke the jqxexpander.

    TypeError: this._header_text[0] is undefined.

    Hi nab054371,

    As far as I know, it is not possible to display expander in jqxGrid or withing jqxGrid cell or as jqxGrid cell editor. Cells display static HTML only i.e Texts, Images, Links – things like that.

    Best Regards,

    Hi Peter,

    Thank you for your feedback. So maybe I did not do a good job at articulating the issue in my last post. I am not displaying the expander in the grid. The expander is being displayed in a diferent div tag, but the display of expander is triggered by a grid row click. So for example, if the grid has 3 rows, upon clicking each row , the expander is displayed in a separate grid element.
