With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

how to add a new row in gridview ?

Asked by tech_question in Programming for ASP.NET, C# Programming Language, .NET Framework 3.x versions

Tags: asp.net

I have the below GridView which is bound to the datasource odsCustomers. How can I add a new row on the click
of the button (btnNewCustomer). I would need to add a new row which pulls all the columns as in edit mode.
eg: in view mode I show the customer code as label but in edit mode I show it as a combobox. when I click
the button a new row should be added with the controls in edititemtemplate or emptyitemtemplate rathern than itemtemplate?

can this done ?
