I want to know how to configure the form so that when I type an employees first and last name in the texbox it will return the entire column of that persons information. Also what parameters should be set for the buttons and the textbox to pull the specific data from the datasource. Below is the codes for the webform:



AJAX :: Restrict User To Type Further If Input Doesn't Retrieve Any Value From Database Using Autocompleteextender?

Aug 25, 2010 02:01 AM

I 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?

Web Forms :: Validate A Textbox Input Against Database Table Column

Aug 14, 2008 02:55 PM

A user input a staff ID in a textbox, e.g. 234255.

The number is validated against a database table column (say,staffID).

I am using SQL server. The table column [staffID] is from a table (say, Staff).

How can I use CustomValidator, a handler to do that? How can I connect to the Staff table and compare the input value against column staffID?

con = new SqlConnection("Data Source=localhost;initial catalog=ams;user id=xx; password=xxx");

If the number matches with one of the records in the database table column, then the textbox pass the validation.

How To Grow A Textbox To Match Size Of Input For Data Entry Dynamically

Feb 3 10 at 19:16

I'd like to add a description field to an application that can be as long as several lines (or even paragraphs) or as short as a one-liner.Instead of taking up a lot of screen real estate or have scroll bars, it would be preferable to have the textbox grow based on its input.

On IE6 adding Style="overflow-y:visible" accomplishes this nicely (both on display of read only, and if we are in edit mode).

However, it has no effect on Firefox, or IE7 for that matter.

Forms Data Controls :: Using Textbox As Input To Populate A Formview Control?

Apr 20, 2010 09:00 PM

I am using a textbox and button to get the user input (account number), this will be used as input to a data access class object (SQL) when the button is clicked. This action should populate the Formview control. I have bound the Formview control to the SQLdatasource and configured the SQLdatasource control to the textbox.TEXT property. What am I missing? What do I need to add to button_clicked event to get all this to work? One other thing, the textbox is in a table area separate from the formview control. I have each of the templates inside of the formview control in tables. The input textbox and button are displayed but the formview control is not, all of this is in a master/detail object.

Rendering - Retrieve The Value Of A Standard Input?

Oct 22 10 at 15:35

I've created a custom server control in ASP.NET to render a standard checkbox and a hidden field like this:

public class CheckAllBox : WebControl
private string checkboxClientID;
protected override void OnInit(EventArgs e)


Now I want to retrieve the value of the hidden field and the checkbox when it is posted back - is it possible with the standard html I have rendered?

I've already written jQuery that works with this markup but it does require a standard html checkbox with a value - not the kind of checkbox rendered by ASP.NET.

If it is not possible to retrieve the value from standard html inputs, do I need to rewrite this as a composite control, or is there another trick?

I have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved.

with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.

Page Cycles - How To Input Data To Database

Aug 23 10 at 16:44

I have a page that has a few textboxes and a dropdownlist. When a logged in user opens this page the boxes are filled with data that he has inputed before, he can change the data and update it by pushing a update button. There is also that dropdownlist which has a dynamically populated data for him to choose from.

What is the best way to make this page work. Where in the page cycles do i populate the forms and where do i input the data to the datatable.

At the moment I'm populating the data on PreRender but the dropdownlist on the preinit. I have a button event handler to do the update on the datatable. The problem is that the autopostback fucks up the data in the dropdownlist because its dynamatically populated, how would i go by fixing this ?
