Forms Data Controls :: Change Formatting Of Text In TextBox Via Server-side TextChanged Event
May 6, 2010
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):
how would I handle textbox text change event in oulhtml 5. I have a text area where i enter project details and i want to store every description i enter in it. which textbox event of html5 should i use? I want to create  an html5 textbox text change event like we have in asp.net I mean the code behind will be in c#.
protected void TextBox1_TextChanged(object sender, EventArgs e
I have a form that contains a TextBox. A pop up window will return a value and put it into the TextBox. when this happens, i need to populate another control. I tried "OnChange" but it was not triggered .
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 have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
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 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?
Basics: I have a text box (txtDepositAmount) that people can enter a deposit amount into and a drop down (ddlSelectedTerm) that sets the terms. Through these two values I calculate the APY (lblCurrentApy).
Rules: If only one of the values is selected I still want to do an update on the current APY label and clear it. If either value changes I want to update the current APY and recalculate.
The problem: As soon as I click away from the textbox and onto the drop down to select my term the drop down flashes and closes because the textbox TextChanged event was just fired.
I have to click on the drop down a second time to be able to select anything!
Do I need to change what event I'm looking at or do I need to move some of the controls outside of the UpdatePanel? Can this only happen if some of the business rules change? Should I just give up and go to javascript?
protected void Page_Load(object sender, EventArgs e) { for(i=0;i<5;i++) { Textbox tbox = new Textbox(); tbox.AutoPostBack =true; tbox.TextChanged += new EventHandler(tboxevent); //Here I need to pass 'i' value to the tboxevent } } protected void tboxevent(object sender, EventArgs e) { Label1.Text = "i value"; }
