C# - How To Get The User Entered Value In AjaxControlToolkit ComboBox When The Enter Key Is Pressed
Jun 10, 2010
The Problem:The user entered value is missing in the .Text attribute of the AjaxControlToolkit ComboBox when the enter key pressed. Also the "on change" events events are not called but I am not using postbacks anyway so I do not care.
Example: private void BuildFileListDetails(NHibernateDataProvider _providerM)
{
int resultsPage = Convert.ToInt32(ddlNavPageNumber.Text);[code].....
My Solution:I needed to access the AjaxToolkit "ComboBox" imbedded TextBox control's .Text to access the value entered by user.
I have added a combobox to my page. Listview is updated based on selection from combobox. It is working great except it does not fire when Enter is pressed. User has to click on option from dropdown or has to press tab key to have Listview to populate. I want the user to be able type use arrow key to select option and then press the enter key for event to fire.
i want to fetch data from Oracle Data base using Tab key , like when user enter ID in one text box and press Tab key it should fetch data in other text boxes , i am using web form.
f anyone else had tried putting a ajax control tookit combobox inside a jQuery dialog div/panel? If I do a postback on a page with this dialog I get an error 'Microsoft JScript runtime error:
Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.' If I continue I get and error and this stack trace;
[NullReferenceException: Object reference not set to an instance of an object.] AjaxControlToolkit.ComboBox.LoadPostData(String postDataKey, NameValueCollection postCollection) in d:hgactServerAjaxControlToolkitComboBoxComboBox.cs:681
If I use a standard DropDownList there is no problem. I will stick to the standard control for now but I would prefer to use the toolkit combobox.
I have a master page and many content pages. In my master page i have LOGOUT button. In the content pages i have many buttons. Now the prob is, LOGOUT button is set to default automatically.. this is very annoying that whenever i wanted to submit the form, i am pressing ENTER key and it is taking me to the login page. So, pls let me know How can i set the particular button_click event to be fired when ENTER key is pressed.
I have a form with several submit buttons. I would like the button's click events to fire when enter is pressed based on which textboxes currently have focus. I am able to specify one button using the code below by adding the onkeydown event to the body of the page and checking for Enter's keyCode
I assume this code can be modified or call a function to perform a conditional to see if txtSearch or txtSubmit has focus and specify btnSearch or btnSubmit accordingly, but I am not experienced with javascript.
I have an html button that makes a certain action and i have two "asp:textbox"I want the html button to be triggered when the ENTER key is pressed on keyboard.
I have a textbox added in an item template so I can enter data. But when I press enter in a textbox it caused the page to postback and I lose the data entered. I can tab through fine but why does Enter cause a postback? Can I disable this?
Now this AddGridAddBTN Temporarily adds a data row to a grid but won't submit that data to database, however AddGridSubmitBTN Submits the data to DB through foreach loop .
Now my query is i want to provide user a functionality that when he gets focus on Abbreviation Text Box OR Description Box and he after typing some data Press ENTER KEY , This ENTER KEY would provide funcionality as a AddGridAddBTN Button , and when he presses SHIFT + ENTER , It works like AddGridSubmitBTN Button , also i want to make Abbreviation and Description Field to be filled must !
Moral is that :
ENTER KEY WOULD DO : Generate a temporary row with holding previous values as it is actually doing on AddGridAddBTN Button.
SHIFT + ENTER WOULD DO : Enter the whole grid data thorugh foreach loop as it is actually doing on AddGridSubmitBTN Button.
I don't want to refresh my page on enter or shift enter pressing . This grid is binded through SQL DATA SOURCE ...
I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
I am using asp.net 3.5 file upload control. I can browse the files when click the Browse button. Same time I can't browse the file when enter key is pressed while file upload control is in focus. I am using master page. I am in urgently need of this.I want to browse the files when enter key is pressed while upload file controll is in focus.
I have a usercontrol which is used for searching. There is a textbox and a search button. When the button is clicked the search method is called. I want the search also to occur when the cursor is inside the textbox and the enter key is pressed.
My first thought on how to do this was maybe to add the event to submit action of the form tag. However this usercontrol has no form tag.
I would like to execute a function when the Enter touch is pressed, how do I do it ? The onClick on the imagebutton is working, but I don't know how to do it when you push Enter after typing a text in the textbox
<td> <asp:TextBox ID="box_mot" Text="Entrez un mot-clef ou le nom d'un professionnel " runat="server" style=" border:0px ;color:#OOOOOO;font-family: arial;font-size:10px; height:16px; width:260px"/> <asp:ImageButton ID="ImageButton1" ImageUrl="img_menu/bt_ok_gris.gif" runat="server" OnClick="rech"/> </td>
And this is the code of the function :
<script runat"server"> Sub rech(Src As Object, E As System.Web.UI.ImageClickEventArgs) response.redirect("result_recherche.aspx?mot_cle=" & box_mot.Text) End Sub </script>
First of all, I'm sorry if I don't describe my problem so well, English is not my first language. I'm working on a project where after the user has pressed a button, the button goes invisible and a label control should say "In 20 mintes you may press the button again". The problem is that if the user presses the button before the current hour is almost over, then he will be able to press the button again. The way I compare the time is by placing th current time, which the user presses the button in a sqldatabase table row for that user. This is my code for the moment for showing the user how long he has to wait:
DateTime TimeSincePressedbutton = Convert.ToDateTime(user.timeSincePressedButton); //value from database TimeSincePressedbutton.AddMinutes(20.00); TimeSpan d = DateTime.Now.Subtract(TimeSincePressedbutton); int dd = Convert.ToInt32(d.Minutes); int timeLeft = 20 - dd; ValPointsTitle.Text = "In " + timeLeft.ToString() + " minutes you may press the button again";
and the code I have for comparing time with the time now, is to see if the user may press the button again (which I know is wrong, just cant figure out how to fix it, the reason I compare hour, day, month, year etc is because if the user doesnt show up online the same day, maybe he comes back after a couple of days, or next month, or next year).
if (timeLeft <= 0 && DateTime.Now.Hour == TimeSincePressedbutton.Hour || DateTime.Now.Hour > TimeSincePressedbutton.Hour || DateTime.Now.Day > TimeSincePressedbutton.Day || DateTime.Now.Month > TimeSincePressedbutton.Month || DateTime.Now.Year > TimeSincePressedbutton.Year) { //button becomes visible and the user may press it again }
I have an ASP.Net UpdatePanel that updates on a timer. Within the UpdatePanel and nested in a GridView, I have a TextBox that the user enters a value in with a submit button. Everything works fine, except if the user does not submit the value before the timed interval, the text is removed from the TextBox. Is there a way to persist the user entry into the TextBox between updates? Is there a better way of doing this?
