View 1 RepliesI have the following scenario: my website displays articles (inputted by an admin. like a blog).So to view an article, the user is referred to Home/Articles/{article ID}.However, the user selects which article to view from within the Articles.aspx view itself, using a jsTree list.So I what I need to do is to be able to differentiate between two cases: the user is accessing a specific article, or he is simply trying to access the "main" articles page. I tried setting the "Articles" controller parameter as optional (int? id), but then I am having problems "using" the id value inside the controller.

I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

I would like to have two different welcome pages for a site.How could I handle this? I've looked at routing but I'm not sure if global.asax.cs is the correct place to place this into.
www.mycompany.com should display generic information. Displaying view Home/Default.aspx
www.mycompany.com?id=1 should display welcome customer x. Displaying view Home/Welcome.aspx
I was expecting a parameter will become a empty string value if the parameter is missing, but it turn out to be null. have I done it wrong for the optional parameter?

View 1 Repliesi have a problem with creating dovs based on the data in the xml file. What i need to do is to create a page where the xml file is loaded and if the give Node has childnodes it should be displayed as a link and after clicking a span or a div with childnode's value should appear under it and afte a second click it should "fold" back. I van use the __postback function from js but the problem is in the dymanic creation of the "child" divs. A portion of the xml file:
<Car name = "Ford">
<Type Name = "Escort">
<Description>Some description of the car</Description>
</Type>
<Type Name = "Puma">
</Type>
</Car>
Given the sample above the value "Escort" should be displayed on page as a link and after clicking a div containing value of the Description node should appear but value "Puma" should appear in normal text as it doesn't have children.

View 4 RepliesI have a question about adding a ListItem to a DropDownList that is being bound by a SqlDataSource.
My Intention is to be able to add an item with something like "0" as a value and "--- Choose Something---" as the item.
However, the control is filled using a SqlDataSource for the DataSource.
So, the question is:
Is it possible to insert the value "0" and item "--- Choose Something---" to the control even though the control has a datasource from the database?

Adding a label control inside of a div will short circuit my image buttons onClientClick method call.
I have an Asp.net panel control. In that markup I have an image button control. My image button when clicked will not call my Java Script method unless the image button control is wrapped with a div or table <td> tag.
That is fine with me. However Just to the left of my image button I have a label control that must be on the same line/row of my image button. If I wrap both the label control and image control in a div or td tag then
my Java Script method is not called. So somehow wrapping the label tag with a div or td results in the short
circuiting of calling my Java Script method.
Why is this? I must have my label and image button control on the same line, so that is the requirement.
I tired using a span tag instead of a div, but that does not work. Below is my Asp.net markup code.

Is it possible to do an optional join as follows?:
private void OptionalJoin(string phrase)
{
from t in db.Table
// (if phrase != string.Empty then) join t2 in db.Table2 on t.Id equals t2.Id
select t
}
Although I'm aware that I can copy/paste this and move the conditional logic outside the query, the query is ~200 lines and there are 4 different optional joins I would like to incorporate, so it would get messy and be difficult to maintain. I'm looking for a clean, streamlined way to do this.
