View 14 RepliesIs there a way to prevent the Enter key from being interpreted as a button click.
I am trapping key strokes at the form level but if a button has the focus and the ENTER key is pressed I cannot trap the enter because the button consumes it as a button click event. I am also unable to trap the enter key in any of the button's key events.
I am interfacing with magtripe swipe and barcode readers that send their information as keystrokes with a CRLF at the end. I have a work around by chaning the focus to a textbox anytime keystrokes are detected but I am hoping for better control.
Is there a way to disable the buttons ability to do this?
one button on/off disable, enable any button like Handles Button1.Click i want to disable or enable part of the program?
View 8 RepliesI am working on an aspx site that lets an admin-level user fill out a form with potential member data. Once the form is filled out, the user will click submit and the data will go off to different tables. One part of the form that is stumping me involves filling out three textboxes (txtFirstName, txtLastName, txtGrade). I have a button (btnAddStudent), that, when clicked, should add the information from the textboxes to a table-like display area. I am trying to use a gridview, but there is nothing to bind it to. There is no memberID number to load a blank record from the Student table (which is a many-to-one relation to Member table). The member record is what this form is creating, and the student data will be added to the Student table when the Submit button is clicked.
I am currently working with the code found in the reply here. But when I click the "Add Student" button, I get a new blank row, but my textbox values are not inputted in the gridview.
Can this work, or do I need to look at using a table and adding rows of textboxes dynamically?
Here is relevant source code:
<tr>
<td class="style8">
<asp:Label ID="Label18" runat="server" Text="Chidren:" Font-Bold="True" Font- Underline="True" Font-Names="Tahoma"></asp:Label>

I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB

Background: I have a GridView which gets populated from an SqlDataSource via DataSourceID. The rows show some summary data from an SQL View. Upon clicking a row, I would like to take my user to another page with a DetailsView control which gets populated with the full set of values from the DB related to the row clicked. My user should be able to edit the data, download files associated with the record, and create a new record of a different type based on said data.
Error: All examples that I've found for Clickable GridView rows end up with some variation of the error Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.

View 1 Replieson my aspx page I have 4 dropdowns and a gridview.Each dropdown is populated based on previous dropdown selection (each of the dropdowns are autopostback=true)and the grid suppose to display data when all dropdowns are selected.

View 4 RepliesI have a page I'm working on with a Gridview embedded into a Gridview. The page uses templates to fill itself out, including the edittemplate for rows. When the row is in edit mode, 3 of the cells contain dropdownlists.I'm trying to filter these dropdownlists to prevent conflicts. The problem is that when the page autoposts back, the row is no longer in edit mode. Is it possible to persist edit mode on that row through a postback and apply the filter I need to?
