Is it possible to draw data from the database and put it straight into a label?

I am listing users in a GridView with:

I have five textboxes(tb1, tb2, ... tb5) on the page, each textbox represent a column in the database table.
I need to search the database table based on the text in the textboxes. User can either enter text in all five textboxes or none.
What's the best way to do a search?
I am thinking for one textbox(tb1), depends on if tb1.text is empty or not, I need to do 2 searches
[Code]....
for two textboxes(tb1 & tb2), depends on if tb1.text and/or tb2.text are empty or not, there are 4 combinations, so I need to do 4 searches
[Code]....
for three textboxes, there are 8 combinations,
Does that mean for five textboxes, I need to do 2 to the power of 5, 32 combinations, 32 if statements?
I'm working with jquery.ajax() I'm getting a object and I use jTemplate to write the html. My problem is now that I need to place the id of the object in a input hidden. I have no idea how I should do this. I tried to do a <script> in the template.htm with jquery to place the id in hidden but with no luck.
this is my jTemplate html file
<div style="background-color: #ccc">
{$T.Email}
</div>
<div style="background-color: #ddd">
{$T.Password}
</div>
This is my jquery

I have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.
However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.

I have a FormView and the SELECT statement I have is as follows:
SelectCommand="SELECT [UserName], [Full_Name_1], [Full_Name_2], [Email], [Address], [City], [State], [Zip_Code], [Home_Phone], [Cell_Phone] FROM [Homeowners] WHERE ([UserName]='<%$ User.Identity.Name %>')"... but it results in the FormView disappearing from the web page. Note: at the top of the page,
<%= user.identity.name %> displays the name fine, so user.identity.name does contain the info I'm looking for.I am trying to figure out how to correctly format the SELECT filter to feed user.identity.name to the SELECT statement as a filter. ... or if there is an alternative way.

I m using a dropdownlist from sqldatasource based on input from listbox like this-
[Code]....
It works very much fine when i select listitem from listbox first time. But when i select listitem from listbox second time, my dropdownlist shows items for second input as well as first input.dropdown should not show items based on first input when i populate it second time.
I would like a situation where there are three textbox available and this would give the user an opportunity to input a value in the textboxes. The value in the textboxes would then be stored in a database table(the table is already created in sql). Furthermore, the value would be able to be reterieved later on when the user presses another button. A sample code will help.

View 1 RepliesI am retrieving list of projects and project IDs using autocompleteextender. Is it possible to restrict the user to type further if the input doesn't retrieve any value from database. Though, I have found a solution by calling function through OnClientPopulated. But this function calls back the webservice "GetCompletionList" method. I don't want to recall one method two times. is there any other way?
