• Why or why not use a DataSource to fill ASP controls?

  - by Brad8118

  So we have a GridView asp control and one of my coworkers doesn't like to use an DataSource to fill the GridView. I wasn't sure if/what the pros and cons are of using one.

• How to modify raw HTML of ASP.NET page on PreRender?

  - by ace

  I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render. How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that.

• How to manually set button input type in ASP.NET?

  - by jawonlee

  I have a jQueryUI dialog with some textboxes, plus a button. Right now, the asp:Button tag used to generate the button automatically sets its type as type="submit". The structure of the dialog is such that pressing enter at any of the textboxes should not call the button click event. It seems like the cleanest way to solve the problem, if it is doable, is to manually set the button's type to something other than submit. Is there a way to do this?

• ASP.Net - How do I allow users to enter html tags in textbox without runtime errors?

  - by Coder

  I have an input textbox on an asp.net page and when a user inputs any tags like break tags or bold an error occurs. I currently am using the following to encode the input: Server.HtmlEncode(mytextbox.Text) However this only encodes characters when they aren't phrased as an html tag, like if the input is "<<<" is there a way for me to allow the user to put the tags in without it leading to a runtime error? Thanks.
