• Focus problem with multiple EditText's.

  - by Ashish

  I have an activity with two edittext controls. I am calling the requestFocus on the second edittext field since by default the focus goes to the first edittext control. The focus appears to be in the second edittext field (the second one gets the highlighted border), but if we try to enter any characters using the hardware keyboard the text appears in the first edittext control. Any ideas why it would be happening?

• Cannot get Request.Form by name in ASP.NET

  - by Nissan Fan

  I have an ASP.NET page which utilizes jQuery for an autocomplete-type scenario. The jQuery tucks the actual selected values into a hidden field it creates on the fly, but for some reason I cannot get the value of that standard HTML field on postback by calling Request.Form["HiddenFieldName"]. I can see it by ordinal in the Request.Form object, but if I add/remove controls it will break. Any suggestions?

• Increasing the character length of the Title Column in Sharepoint Site

  - by Nathan Fisher

  Is it possible to increase the length of the Title column for a site above the 255 characters. My requirement is that I use a field that is longer than the maximum 255 chars but because the Title column is a required field I need to enter something in it. Rather than enter garbage just because I have to, I would like to use it. If not, then my current thoughts for a workaround will be make a copy of the first 255 chars of a seperate column that I am able to make longer.
