DataSource Controls :: Selecting All Data From A Table Based On Some Given Conditions?

Jul 8, 2010

I am having a staff table which contain staff information on it. To search staff information from the table, I want to prefer filter style. For example in the select query I want to display staff information according to three criterias. Select staff information from all sections, Select staff information from a given section, select staff information by a given Name. All these selects must be performed in a single select statement. Suppose,

SELECT * FROM StaffDetailsTbl
WHERE SectionID = CASE WHEN @SectionFilter IS NULL THEN [SELECT ALL]
ELSE SectionID = @SectionFilter
and Name = CASE WHEN @NameFilter IS NULL THEN [SELECT ALL]
ELSE Name Like '%@NameFilter%'

Where Declared variables are parameterized stored procedure values retrieved from the user.

Proper Way To Populate Dropdownlist Based Off Another Value?

Dec 21, 2010

I'm running into a minor issue with some ASP.Net code I'm working on. For simplicity sake lets say I have two dropdownlists, one that is full of various items and another that is full of other items, but based off the selected item of the first dropdownlist. I currently set variables into hidden inputs to check to see if the item in the first dropdownlist has changed and if it has to change the second dropdownlist, but I'm also having to check to make sure that if something else causes a postback to NOT repopulate the second dropdownlist as to not lose what is currently selected by the user. This check also allows me to make sure that when I navigate away from the page, the correct values are selected and not something replaced by a postback repopulation.

I'm new to ASP.Net/HTML/CSS/Javascript and the like. I know while what I have works, it isn't even close to being the correct way to do things. correct my ways and figure out the BEST way to solve this current problem. Some good ASP.Net tutorial websites would be nice too as I need to keep improving my skills with it.

Unique Content Within Master Page Based On Conditions Met?

Aug 20, 2010

would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx). The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML, Divs and databound gridview content. The HTML content will be stored in the database.

Forms Data Controls :: Programmatically Populate A DropDownList In A Formview?

Apr 24, 2010

I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!

Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.

I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

[Code]....

This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range

Forms Data Controls :: Populate DropDownList In InsertItemTemplate After Insert?

Sep 18, 2010

I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.

How can I fill those DropDownLists?
