Web Forms :: Scroll Back To Drop Down List After Auto Post Back In Code Behind?

Feb 22, 2011

Using Vb.Net 2003 Asp.Net 1.1

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.

Problem is: when the page comes back it is at the top of the page not where i have the control.

I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.

Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.

I really don't want to use Page.Register new Script...... code if I can avoid it.

What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";

i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.

i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.

In ASP.NET 4.0 RC2 the Menu Control by default emits Javascript like this:


There should be a feature coming up to disable this, but I think it's not in RC yet. At least it's not working for me.

Now, the problem is, that this Javascript kills my own Menu Javascript (I use an CSS Adapter). Is there a way to overwrite the stuff that comes from the Menu control? Can be a hack, just need something until this is fixed by MS.

MVC :: Drop Down List As Filter On List View?

Jan 7, 2011

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.

Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.




I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.

Web Forms :: Binding A Drop Down List

Mar 3, 2010

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.

I have also set the Text property of the Drop down list


However, it is not populating the DropDown list, what should I do?
