Good morning, Before starting this post I want to state that my English is not very good. I have a doubt I'm programming an aspx page where I have a webdatagrid control which has a column of type templatedatafield. This template contains a WebDropdown control. Each row represents a product webdatagrid and the template of each row contains at webdropdown indicating the product units (kilograms, pounds, etc). So my problem is that when I view the screen in edit mode I have to load their products with these webdropdowns webdropdowns and their respective items depending on the product. At the time I was able to add rows to overcome the impasse with the code show later but when I view the page in edit mode or modification only managed to load the last webdropdown. If you do not mind would like to receive many suggestions. It should be noted that working with an object webdatagrid datasource.
aspx code:

Sorry for the code coment, thanks.
Hi abanda,
Please let me know if you need further assistance regarding this matter.

Thank you for posting in the community.
In this scenario I would suggest that you use a DropDownProvider as an editor control for one of your grid's columns instead of using a templated column. This would be more efficient as only one provider would be instantiated (as opposed to n WebDropDowns where n is the number of rows in your grid). Detailed instructions on how to setup a DropDownProvider can be found at:
http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.2/CLR4.0/html/WebDropDown_Using_WebDropDown_as_an_editor_provider_for_WebDataGrid.html
From what I understand you wish to have different items loaded in each row in the dropdown column. I would suggest that you lazy-load the items according to the row's values as illustrated at:
http://help.infragistics.com/NetAdvantage/ASPNET/2011.2/CLR4.0/
The above article is for the WebDropDown, however the principle is the same for the DropDownProvider. In your case I would suggest that you load the items in the CellEditing_EnteringEditMode client-side event.
Please let me know if this helps.
