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):

<td>
<asp:TextBox ID="txtDepositPercent1" runat="server" AutoPostBack="true"
CssClass="TextboxAnimatedRightAlign" Width="33px"
Text='<%# String.Format("{0:0%}", Eval("fld_dep1")) %>'
OnTextChanged="txtDeposit_TextChanged" />

Web Forms :: Text Change Event Eats Up Button Click Event?

Feb 18, 2011

I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

AJAX :: Change Label Text From An Event?

Aug 18, 2010

I have a component which is listening a server from TCP/IP.

When somebody connects to the system my component's Connected event is fired.

I want to write to a label when this event is fired without postback.

I used UpdatePanel. And I know about AsyncPostBackTrigger.

But my component is not a visual component. So I declared in codebehind. So I can not use AsyncPostBackTrigger.

How can I set my label.text value when component's event runs.

C# - Change Textbox Text In JavaScript?

Oct 7, 2010

I'm allowing a user to use either one of two textboxes to search a database - one is an ID field, and one is a freetext field. I'm using ASP.NET with C# btw.Anyway, all I need to do is have it so when a user clicks on one of the text boxes, the other text box text is simply deleted, so the other text box is blank. How would I do this? I'm guessing JavaScript is the solution.

Trigger The Change Event Of A Textbox In JQuery?

May 17, 2010

I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed.

<asp:TextBox id="myText" runat="server" />
<asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator>
$(document).ready(function(){
$('[id$=myText]').bind('change',function(){
//do something........

and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception.

What happens is that the page is left with just the watermark text, but not the text I'm setting it to. However, if I inspect the textbox in VS it says the text is what it's supposed to be. I read somewhere that a similar error was because of a property referred to as isWatermarked, but I couldn't find it.

Forms Data Controls :: Text Change Event Should Not Fire?

Dec 29, 2010

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]

I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.

Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.

Example:

When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???

I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.

Here, is my one of the image button event. (Remaining image button events are almost same)

[Code]....

My text box change event.

[Code]....

My page load Code: Note: PageUniqueIdr = PageUniqueId retrieved from the QueryString.
