I want to add another sql query which is using two tables to fetch the data and than i want to display it in a dropdownlist after fetching data from database. How should i proceed?? Should i create a totally new connection? I tried many different ways like, creating new connection and new reader and entire try and catch block i coded again but on running the website i t was taking very long to load the contents. What i did i modified only this portion(below code) and used the entire try catch again but it dint work.
while (MyReader1.Read())
{
String f = MyReader1["ret"].ToString();
DropDownList1.Items.Add(f);
}

Verbatim - Why Write @ Before Sql Queries - Select Data From Database Then Write Query?
Oct 1, 2010Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?

View 9 RepliesWeb Forms :: Write URL / Button Click Event That Sets Eventtarget Value?
Apr 20, 2010I'm working with a third party product and my boss wants to be able to link directly to a specific screen in this product from our company intranet. When I drilled all of the way down to the screen in this product, I see that it is an ASP.Net application and the particular screen is reached via a link that triggers a javascript function. I can see the anchor tags for this link and a link to a different screen and I can see the javascript function. Both screens as well as the initial screen are all part of the same content form. It is pretty clear that this screen is modified based on which link is clicked but it isn't using query string values so it must be using button click events to modify what shows on the screen. My question is; with what I can see of the 2 links and the javascript function, is there a way to send a postback with that specific click event from a different site to that specific ASP.Net form so it would pull up the correct screen? Here are the javascript function and anchor tags:
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
