I am using the following line is my code and the onTextChanged event is not firing. But when I use the onClick event on the same code, it's firing.
textbox1.Attributes.Add("onClick", "SetValue();")
But I need to do my calculations only if the value in the textbox is changed not when the user clicks on the textbox.
On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).
I here's the client-sdie code for the page (at least what pertains to this):
[Code]....
And here is the server-side:

I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
View 1 RepliesI am using a calendar extender which is an Ajax control I am selecting a date but the event is not fired.
The reason I am doing this is because I am setting an expiry date based on the date selection.
<asp:TextBox ID="start_date" Width = "165px" Height = "24px" runat="server" OnTextChanged="start_date_click"
></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" Enabled="true" TargetControlID ="start_date" WatermarkText="Start date" runat="server">
</asp:TextBoxWatermarkExtender> <asp:CalendarExtender ID="CalendarExtender1" Enabled="true" runat="server" TargetControlID ="start_date" >
</asp:CalendarExtender>
The code behind
protected void start_date_click(object sender, EventArgs e){
DateTime begindate = DateTime.Parse(start_date.Text);
exirydate.Value = Convert.ToString(begindate.AddDays(days));
}
Is my codebehind code correct. Am i not doing in a right way.
I got a formview which has a textbox control, when I tab to the next box, OnTextChanged doesn't fire.
aspx page:
Following code is in <InsertItemTemplate> in FormView
<asp:TextBox ID="txtPhone" runat="server"
AutoPostBack="true"
OnTextChanged="txtPhone_TextChanged">
code behind:
protected void txtPhone_TextChanged(object sender, EventArgs e)
{
....
TextBox Phone = (TextBox)fv.FindControl("txtPhone");TextBox
....
}
I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.
I have 10 text box in a page like txt1,txt2...etc
In text box onchange i call the javascript function
for calculating txt5 value
i.e.
in javascript method,
txt5.value = parseFloat(txt1.value) + parseFloat(txt2.value) + parseFloat(txt3.value) + parseFloat(txt4.value);
and
text box txt5 enabled=false,autopostback is true
protected void txt5_TextChanged(object sender, EventArgs e) { // here based on txt5 value i getting records from database and doing some calculation and display those value in txt6,txt7
}
The problem is the textbox txt5 can;t post back when text change from JavaScript function.
How can I do postback when text box value bind from JavaScript function and enabled=false.
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" onchange="calculate()" runat="server" Text="0"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>

I'm getting this error on the above markup: Message 1 Validation (ASP.Net): Attribute 'onchange' is not a valid attribute of element 'TextBox'.
I am creating a html table dynamically with some content and along with that want to add asp.net textbox control under one of its row. I am adding the control as

Text='Go' OnClick='btnTotal_Click' /></td></tr>
I want to call the OnTextChanged event of a static control added on aspx page.But the textbox is not getting displayed.Similarly I want to add a asp.net button also but it is also not visible.
I've the following problem: asp.net TextBox server side control, fire onTextChanged only when it loose focus.
I would like to fire my server side event each time user press a key.
How can i do ?
I have a TextBox control with OnTextChanged handler. The event handler is working fine most of the time, but when the user changed the text and press Enter in FF, the OnTextChanged event is called twice. I observed the problem in Firebug that the first request is actually canceled because of the second event.

Put a break point @ var a, and you'll be able to see that after changing text and press enter in FF (v3.5.7), the OnTextChanged event is invoked twice.
So my question is, what's the best way to properly handle OnTextChanged event so that hitting enter in the textbox doesn't trigger double postback.
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:
txtOrderID.Attributes.Add("ontextchanged",....
Rather than hardcoding client-side JS....
I have a textbox in my app in which I have code behind in the "onTextChanged" event that I'd like to execute
without doing an entire page post back .
I can't use use AJAX not an option for me (corporate thing).
Anyways, I have been struggling with the specifics on implementing ICallbackEventHandler. Or is than another way I can/should do this.The code in the textChanged event pulls a dataset from the DB and does a validation.
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 form action in an ASCX page set to an external URL
<form id="fLoginForm" runat="server" action="http://external.url" method="post" defaultbutton="bSignIn">
Inside there is a standard ASP linkbutton
<asp:LinkButton CssClass="btn" ID="bSignIn" runat="server" Text="Sign In" OnClick="bSignIn_Click" />
The event "bSignin_Click" never gets fired when I have ction="http://external.url" set on the form tag. However when I remove the action, it works as expected. I thought for runat='server' forms, the form would always post back? I need to read the URL from the action attrib and then redirect to it with some hidden input values also in the page.
How do I do something like the following:

I have four Itemtemplate textbox with in my Gridview.... i want to set Readonly attribute dynamically only one itemtemplate textbox, how to do that,

I have a bunch of controls in a Content Page ( A registration page, right) to gather information concerning a user. One of controls is for the UserName. I want to check that the UserName is unique so I place code in the TextChanged event of the TextBox control for the UserName. I have abreak point set in the event procedure and it never gets hit! This is my first attempt at using Master/Content pages. I have looked in the MSDN Library for many hours concerning this problem without any success. I need to know how to check whether the UserName is currently in an Access database.
View 5 RepliesI have a simple search user control that consists of a textbox. The textbox's onchanged event appends the entered text to another page address and response.redirects to that page. The target page reads the query parameter and displays the results. Works great the first time a search term is entered. The problem comes if I immediately enter another search term, instead of refreshing the search results page with the new query parameter, it jumps back to my default.aspx page. I'm not sure where its getting that as an address to redirect to, the only control with default.aspx as a target is a imagebutton on my master page. I've tried turing off the autopostback on the textbox but it didn't help the problem.
Here's the search user control

If I declare a DIV and set it to runat server I get a clientmode attribute which I can set to determine what the ID comes out to be on the rendered page. I need to do this for a drop down and a textbox but clientmode isn't available on those controls. What can I do? I don't want to do some crazy workaround. If it comes to it i'll just do an auto postback and do what I need there.

Are there any other events besides the OnTextChanged event? Like is there a key up event of some sort?
What I'm trying to accomplish is when a user fills in this text box it automatically fills in a couple other text boxes.
