How to change the datasource of one dropdown column in UltraWinGrid by changing the value of other dropdown column in Grid
posted

I have a datasource like City with columns Country, City etc. I bound these rows to grid. Both Country & city are dropdowns.

What i want is to change the values in City Column dropdown on changing selection in country Column dropdown.

I want to use "Infragistics2.Win.UltraWinGrid.v8.1" in my project. If i can find solution for this problem i will go ahead with Infrasictics as i am facing lot of issues in writing same logic in datagridview.

In Article "http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.aspx?ArticleID=4878" same functionality is explained but for v5.3. I guess that Infragistics must have enhanced this working in v8.1 , so looking for a solution of same problem in v8.1

Awaiting a quick response.

    The best thing to do is to populate the City dropdown with a list of all possible cities, then use the ColumnFilters to filter out the cities that do not apply based on the value in the other cell. I would recommend using the BeforeCellListDropdown event for this, or maybe BeforeCellActivate.
