Web Forms :: .net 4.0 - Inserts Blank Spaces Into Multi-line TextBoxes?

Aug 11, 2010

I've updated a number of production sites from 3.5 to 4.0 and have found a really annoying problem where it will insert a blank space into Multi-Line text boxes

The tag is entered as....
<asp:TextBox
ID="AdvDayNotesTB"
runat="server"
TextMode="MultiLine"
CssClass="text"
Width="99%"></asp:TextBox>
<asp:TextBox
ID="AdvDayNotesTB"
runat="server"
TextMode="MultiLine"
CssClass="text"
Width="99%"
/>
The HTML is rendered as...
<TEXTAREA style="WIDTH: 99%" id="ctl00_C_FV1_AdvDayNotesTB" rows="1" cols="20">

Web Forms :: Blank Spaces After Zip And Why Do They Causes?

May 3, 2010

I've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.

Multi Line Text Box With Line Breaks

Jul 28, 2010

I insert a text box, change the parameters to multi line and then pass the string to sql. Users insert comments etc, using line breaks, however because I just pass this as a string the line breaks are not there when they view the text box after input. Example: Here is a well formatted comment. as I typed in the text box today. Inserted in to sql as a string, returns this on select:

Web Forms :: Preventing Copy And Paste Into Our Multi-line Textfields?

Jul 12, 2010

We have a number of multi-line text fields on our pages for form submissions. On the backend of things, we have our stored procedures checking for html coding in those fields to help prevent sql injection. In some cases, someone that is completing the form without any malicious intent is copying and pasting from their word resume into our text fields and once they submit the page it fails because word uses html encoding for formatting and such. So is there a way to either prevent pasting in that way or maybe a way to submit the data to sql in plain text?

Just looking for the easiest solution so that the user doesnt have to do multiple things to submit their application. In order to get it to work for anyone having issues, is to have them copy and paste into "notepad" and then copy and paste from there to our form, which strips the html coding.

Web Forms :: Labels And Textboxes Won't Line Up

Jan 22, 2010

I don't know if gnomes came into my office over night, but suddenly things aren't lining up on my form anymore.

I want a label over a text box and both to line up on the left edge.

I made two css classes one for a field that starts on a new row and one for a field that floats left next to a previous field.

[Code]....

For each of these I make divs and put the asp controls in the div

As usual the designer completely lies about how things will really look. When I view my site the labels are above and about 1 character to the left of the textboxes underneath and my check box control somehow decided to go to a newline for each word in it's label.

I can't figure out what I did wrong. I've went over the css several times.

Forms Data Controls :: Repeater Textboxes - Unable To Fetch The Values Of Textboxes

Aug 11, 2010

I have a repeater which is binded using a Collection of Entity Data Framework.

Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.

The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.

I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.

Here is my code

Repeater.aspx

[Code]....

[Code]....

Repeater.aspx.cs

[Code]....

Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.
