AJAX :: Onchange Event For Textbox Not Firing Inside Updatepanel?
Oct 24, 2010
i am developing the webpage using Visual 2008.In that i have i am using update panel and displaying values in the textbox bby using webservices from sql database.I need this thing if textbox values changes i need to change the backkground color of the text box also, so that user can easily identify which textbox values are changing. like this i have 5 more text boxes control in the same form .i have tried but i could not able to get done. i have written javascript code on change event of the text box it does work.
I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator) 2. Click the Linkbutton (fires two validators) 3. Uncheck the checkbox (which should disable requiredfieldvalidator) 4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.
I have a ImageButton inside a gridview. The gridview is inside update panel. i want to redirect to another page with the Clicking of the ImageButton. But it is not working inside update panel. what should i do?
How can I get a gridview (that is inside an update panel) to update/filter whenever something it typed into a related textbox outside that panel..( possibly in another update panel)?
As in Google. When you start typing, it starts autocompleting for you by looking up words in the background using the text you've typed.
I want, in effect, for a user to start typing in a textbox (say "Order #" textbox) and each time a character is typed, to trigger an update to a gridview that has a 'search param' in it's SQL Datasource SP that plugs the textbox's text into the where clause of the select inside the SP...
make sense? I have the SP and all other related code, I would just need to know how to create a JS function (preferably via server-side using something like:
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:
I have a sample I got from the web (link is in the code). It colors the background on a control's contents if they've changed (visible change indication for the user). However, when I change a textbox to Multiline it fails. How can I fix this?
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
Button click event from inside the accordion pane is not firing. Accordion pane contains tab container inside one of its panes (5th pane) to read data from user and to save that data into database. I have used a button to save data when user click on that button. For this button i have written a click event in code behind.
i hv a gridview in modal popup,I hv taken checkboxes in itemtemplate and written code in javascript function to checked or uncheck the checkboxes.and in pageindexchanged event calling that javascript function to maintain the state of checkboxes.it is working fine.but when i put it inside update panel nothing is happening.
I have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?
I had been created some dynamic radio buttons in a loop inside a dinamy table which is inside an UpdatePanel , but i can not handle the events my code is below:
public void MetodoCreacion() { RadioButton RBtn = null; Table table = new Table(); TableRow row = null; TableCell cell = null; for (int i = 0; i < 5; i++) { row = new TableRow(); cell = new TableCell(); RBtn = new RadioButton(); RBtn.ID = "RBGN_" + i.ToString(); RBtn.GroupName = "RBGN1"; RBtn.Text = "Opcion " + i.ToString(); RBtn.CheckedChanged += new EventHandler(RBtn_CheckedChanged); RBtn.AutoPostBack = true; cell.Controls.Add(RBtn); row.Controls.Add(cell); table.Controls.Add(row); } UpdatePanel1_UpdatePanelAnimationExtender.Controls .Add(table); } public void RBtn_CheckedChanged (object sender, EventArgs e) { Label1.Text = ((RadioButton)sender).ID; }
I am having a DOB text box. This text box also allows to enter the date and also to pick the date using ajax CalendarExtender.
I used to set the dirty message when we edit some thing in the page.
When I enter some thing on the text box and click on the cancel button, dirty message will occur.
The problem i am facing is that, in Edit mode, I used to get all the records and assign to the text box. In that scenerio, the dirty message si automatically set since the DOB gets changes.
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I have a calendar extender tied to a textbox. When I select a date from the calendar, it displays the selected date in the textbox. When I click a submit button, it passes no value. why the textbox doesn't store the value from the calendar?
I'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).
In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:
aspx:
form id="form1" runat="server" defaultbutton="Button1"> <asp:ScriptManager ID="scriptManager" runat="server">
i am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?
