Controls - Textbox Will Not Postback On Textchanged If Set To False On Pageload?
Jan 31, 2011
I have a textbox with a regex validator attached to it and some stuff in the ontextchanged code behind. This all works fine unless I start the textbox out with Visible=false. Obviously, I'm setting the textbox.Visible to true later on in the codebehind, but when I do this, no postback occurs when the text changes. I'm pretty sure I have isolated the cause to when I change the visible property, but has anyone seen anything like this or know some sort of work around?
I've got a GridView, with a TextBox designed in the template field. Im binding values to the textbox from ObjectDataSource.I've attached a textchanged event to the textbox, to capture the rowindex when a particular textbox value is changed by the user.
Each textbox has a TextChange() event wired up for data validation.
These events fire just fine, the data validation works just fine.
My issue is this: User enters text into TextBox1 one then tabs into TextBox2. The cursor appears for a split second inside of TextBox2 then disappears as focus is being set somewhere else on the page. I'm not sure how that change of focus is happening.
In this scenario, after tabbing out of TextBox1, how can I maintain focus on TextBox2 (and then subsequently TextBox3, TextBox4,etc..)
I have a repeater control. show my products. in the quantity column I have a textbox that fills from database, the problem is when I want to update the quantity from the textbox, how to get the id of the row repeater and the value of the textbox to update the record. try using the method OnTextChanged. or maybe Jquery?.
I aam working with textChanged event in a textbox to validate a value in textbox.hen i am enter data in textbox then press submit button i am getting validation summary before the textbox textchanged event. Is there anyway to fire textchanged event first to validate before button validation summary?
I have a series of textboxes on a FormView. There is a textbox for entering a percent for a deposit amount and next to that a corresponding textbox for entering a dollar value for a deposit amount. There are 3 sets of these.
If a user changes a percent textbox, I update the dollar value textbox based on the percent times the project's total cost. If a user changes the dollar value textbox, the percent textbox gets updated as a percent of that dollar amount divided by the project's total cost.
I have the percent textboxes formatted as "{0:0%}" and the dollar value textboxes as "{0:C}".
When a user types into the textbox, the formatting goes away and we get raw numbers but I don't want those raw numbers to remain as such after they tab or click out of the field. I added a TextChanged event to reset the formatting. This works fine on reformatting the percent textbox but the currency one remains as just a raw numeric value.
Here is the markup (ignore the lack of validation for numeric input only...it will be added):
I'm having a pretty nasty problem with an auto-completing textbox. I want to initiate an asynchronous PostBack whenever a user selects an item from the auto-completed field and retain the value of the item, rather than the text inputted. This works perfectly when enter is pressed rather than a mouse click.
An example of my issue:
Someone goes to the page, and types 1000 into the textbox. The autocomplete displays 10002, 1000B, and 10000. The user clicks on 1000B and an asynchronous PostBack initiates. Instead of 1000B, the TextBox.Text value is still 1000. My assumption is that the textbox is initiating the PostBack before the value is actually getting assigned to it.
I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!
I haven't been able to find anything on the net about this yet. A project that used to work fine all of a sudden started having trouble with a couple users. The TextBoxWatermarkExtenders for these users are now always firing the TextChanged event of the textboxes they are assigned to for every postback. I don't think this is what they are supposed to do. They didn't use to do this. Has anyone else experienced this? I can add code to ignore these unintentional events, but I would like to know why all of a sudden the change in behavior.
In my web form I have a Textbox control. The TextChanged event of the Textbox is not triggering. AutoPostBack is set to true What could be the reason for this?Here is the code:
I have aspx page in which i have three textboxes textbox1,textbox2 and textbox3.
The value of textbox3 is subtraction of textbox1 and textbox2.I wrote this in textbox2 textchanged event.It's working fine,but after that if i press tab it's not moving to next control. I think textbox is postbacking again that's the problem.......
i have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?
Here is my page in this, there is a control txtLicenseNumber.On the text_changed event of this control my code executes but data does not shows in my control after the completion of execution.if i commented the Panel(pnpPopup) & modalpopup from my source then it works fine.What should i do to work it with modal popup ?
i have the following two asp.net pages the default contains two textboxes and a button the second contains textbox with a button i saved the value of the textbox in the seconed page in session["1"] when click the button in this page it will redirect you to default in the default page on pageload events i have check the values of the session if one it will appear in textbox 1 if it tow it will appear in the textbox 2 but i lose the old values of the textbox when another get filled please tell me how to keep this values after it filled and the page load ,the session get the value to fill the other textbox her is the code: defualt protected void Page_Load(object sender, EventArgs e) { if (Session["1"]!=null) { switch (Session["1"].ToString()) { case "1": TextBox1.Text = Session["1"].ToString(); break; case "2": TextBox2.Text = Session["1"].ToString(); break; default: break; } } } protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("WebForm1.aspx"); } webform1 protected void Button1_Click(object sender, EventArgs e) { Session["1"] = TextBox1.Text; Response.Redirect("Default.aspx"); }
