Unable to Backspace or Delete Characters In TextBox with FilteredTextBoxExtender in ASP.NET in opera browser. here is my sample code.
<asp:TextBox runat="server" ID="TextBox1" MaxLength="20" />
<asp:FilteredTextBoxExtender TargetControlID=" TextBox1 " ID="FilteredTextBoxExtender1"
FilterType="Numbers,UppercaseLetters,LowercaseLetters" runat="server">
</asp:FilteredTextBoxExtender>
We're currently using FTEs to filter input on our registration. New business model wants to explore foreign markets, and I have not been able to figure out how to get the FTEs to accept foreign language characters.

<asp:FilteredTextBoxExtender ID="FTBE1" TargetControlID="txtadd" runat="server" FilterType="LowercaseLetters,UppercaseLetters,Numbers,Custom" ValidChars=" ">
</asp:FilteredTextBoxExtender>
Now problem is that when I want insert text in persian language it didn't insert I can just enter text in English language...
i am using ajax combobox.it works fine for fetching and updating data.but when backspace or delete is press the it gives error :
Message: 'this._optionListItems[...].text' is null or not an object
Line: 1157
Char: 17
Code: 0
I have a situation. I know that backspace and delete don't work if we have asp textbox linked with MaskedEditExtender inChrome browser(may be other browsers have the same situation)but I've written some javascript to handle this.
<asp:TextBox .... onKeyDown="KeyDownHandler();"...../>
and in KeyDownHandler I check if it is backspace or delete key pressed and do manipulation with textbox text manually soat the end I have real normal text.And During editing text in textbox everything is fine but as soon as I get focus on another control .. text changes back (as it was before editing)What should I do to change the real text in textbox ? Now I am operating with textBox.value property but It seems MaskedEditExtender save this value or something like this.I found some property in MaskedEditExtender - MaskedEditExtender._LogicTextMask but if I change this .. it works only for particular mask of extender.....
I used below code for textbox
<cc1:MaskedEditExtender ID="MEE1" runat ="server"
TargetControlID="Txtprice"
Mask="999,999,999,999"
MessageValidatorTip="true"
MaskType="Number"
InputDirection="RightToLeft"
AcceptNegative="Left"
DisplayMoney="None"
ErrorTooltipEnabled="True" />
Here if I enter wrong digit and want clean wrong digit it doesn't clean I mean I should select all digit and type again
i.e:
I want enter this number==500,256,325
if I enter 500,44 and want delete 44 and type correct digit(256) it doesn't clean it I press backspace but it doesn't clean it...
I'm using FilteredTextBoxExtender (Ajax ControlToolkit) to avoid entering unwanted charecters.
its working according to my requirments But I want to display message when user trying to enter Invalied charecters.
Is there any such options in FilteredTextBoxExtender
I'm looking for a simple solution to disable the IE functionality of the backspace key behaving like a back button. I have textboxes that are dynamically set to read only depending on certain criteria. If the user hits the backspace key when focus is on a read only textbox it navigates back a page. I would like to disable this functionality.
View 6 RepliesI need to filter user input into a textbox - as the user inputs the text (as opposed to examining the textbox on the textchanged event) The FilteredTextboxExtender does the trick, but there is a catch. I want to add formatting (currency) AFTER all of the input is collected in the textbox. The "FilteredTextboxExtender " prevents this from happening. This extender does have a property "Filtermode" which can be set to either "ValidChars" or "InvalidChars" at design time, but I do not know if it can be set at runtime.
Any solutions would be most appreciated. I am also open to other solutions to the problem - which is : do not allow chars other than numeric into the textbox, until the textbox has lost focus, at which time, currency formatting is to be applied.

View 1 RepliesI have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....

how can I allow only alpha characters into a dynamically created textbox? I don't think I can use a regular expression validator for this issue. Unfortunately, I cannot use Ajax for this issue either.

I have a page that displays content retrieved from XML with no problems:
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<Fields>
<NamePrompt>名字</NamePrompt>
</Fields>
</Root>
Page encoding is set to GB18030 and it displays perfectly. However, when I retrieve inputted text from HttpContext.Current.Request.Form that's been entered with double-byte characters, the retrieved string contains unreadable characters. Single-byte characters are fine, obviously.
I've tried the following to no avail:
byte[] valueBytes = Encoding.UTF8.GetBytes(HttpContext.Current.Request.Form["fullName"]);
string value = Encoding.UTF8.GetString(valueBytes);
I don't see this problem with other double-byte languages like Japanese or Korean. How can I successfully retrieve double-byte characters from a page that's GB18030 encoded?
