It does not work. Why is spaces causing problem here? How do I get it work?
I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.
I am attempting to pass a small xml doc as a string to an affiliate's classic asp page. Here is how I am doing it:
[Code]....
However, when they receive this info the spaces are stripped out of the xml tag causing it to not parse and be invalid. Here is what it looks like when it arrives:
<?xmlversion="1.0"encoding="utf-8"?><test_ping><id>123456789</id><zipcode>99998</zipcode><income>3200</income><dob></dob><source>affiliate1</source></test_ping>

I have a long string containing the ,<p> </p> and <br>. I want to clean my string from all these tags and spaces. How it can be done with String.Replace() method. I am doing separately right now, it is working but is there a way to do it at once, without replace() method.
String.Replace(" ","").Replace("<p>","").Replace("<br>","")
It is giving me clean code but I am looking for a general solution, means if I am having more tags (10 to 20) to filter then how to do it efficiently.
Is there any way to use a validator that shows an error mesagge, if the user leaves a textbox blank (empty string)? Note: in this case I can use RequiredFieldValidator, because the control I want to check for empty string is on a modalpopup (which is not visible most of the time) and the RequiredFieldValidator then blocks the Buttons on the rest of the (visible) page.

View 2 RepliesWith script below, request to the server always sends empty string (even if value is not emtpty), where the data line is:
data: "{ 'folderName': '" + $(this).val() + "' }"
The html element under investigation is this:
<asp:TextBox id="searcher" runat="server" ClientIDMode="Static" CssClass="classificationFolder" />
Script is:
<script type="text/javascript">
$(document).ready(function () {
$(".classificationFolder").each(function () {
[Code]....
The reason that I select elements by css class selector ($(".classificationFolder")) is that, this control is a user control and used in the same page more than once. That is why I'm not using $("#searcher").
I tested the code In IE8 and Chrome 8.0.552.28 beta. This issue is arising in both of the browsers.
On the other hand, request is sent to the server, client received response successfuly and response is processed on the client.
I'm stuck getting a value from a textbox in code behind. I have tried
Code:
string s2 = txtEmployeeNr.Text;
and
Code:
string s1 = Server.HtmlEncode(txtEmployeeNr.Text);
And just get an empty string.
I have used the last one before with good results.
This doesn't work. I've got an exception from SQL databse that column does not allow nulls.

I define the datasource in my c# code and I have a submit button which takes the value of the radiobuttonlist

I have string. There are no items to show in this view of the "Personal Documents" then assign to string str variable string str ="There are no items to show in this view of the "Personal Documents" library" Now planning to replace "" and make it to actual string to str object. I tried below, but did not worked
str = str.Replace(@"",string.Empty);
I want str value should be string str ="There are no items to show in this view of the "Personal Documents" library" I need to find this string in another string. While searching into that string. I couldn't found because str contains "".
Is there any way that can I set default value as Empty.string in Model.
I have a column Name in the Model its not null field in the database with default value is Empty.string
is there any way that I can set this default property in the Model for this column?
This is completely frustrating and probably embarrassing as well. A while back I posted a similar question and resolved the issue. [URL]...scope_identity The program has been working ever since, until yesterday when as it turns out SCOPE_IDENTITY() started returning an empty string even though a record is being inserted. I am not sure what has changed since the fateful day.
[Code]...
I am hoping that there is something I am just not seeing here. A lot of the information I have seen thus far indicates that there are problems with SCOPE_IDENTITY() but most of those are related to inserting multiple records. As you can see this should be fairly straight forward. The thing that really has got my goat is that it used to work and now it doesn't. If someone could take a look at the above code and comment on any anomalies it would be great. Also I have heard suggestions for switching to ADO.NET and it is beginning to look a lot more attractive every day. But I have a ways to go before making the switch so it is SqlDataSources for now
