Web Forms :: Get Rid Of Empty Spaces Before String?
Oct 18, 2010
I have a textbox where email addresses are displayed at the click of a button. There is one problem, before the first email address there are two empty spaces. Is there any way of getting rid of them? The result looks like this: " emailaddress; emailaddress; emailaddress;"
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
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:
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.
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.
When my LinkButton1 button is clicked in the gridview below, I would like the Gridview1_Rowcommand to assign the ID1 to the index variable. I am getting a "Input string was not in a correct format." error. The e.command argument is an empty string
I'm trying to Exit the Page_Load event if the user did not come from a specific page. If it did I want it to populate the fields based on what i passed from the other page. Here's my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Request.QueryString Is Nothing Then Exit Sub ElseIf Page.IsPostBack Then NCMRNumber.SelectedValue = Request.QueryString("NCMRNumber") NCMRLabel.Text = NCMRNumber.SelectedValue Dim SQLDataview As DataView = DirectCast(SortInstructionsSQL.Select(DataSourceSelectArguments.Empty), DataView) For Each DataRow As DataRowView In SQLDataview SupplierNameLabel.Text = DataRow("Supplier").ToString SupplierContactLabel.Text = DataRow("SupplierContact").ToString SupplierPhoneLabel.Text = DataRow("SupplierPhone").ToString PartNumberLabel.Text = DataRow("PartNumber").ToString DefectDescriptionLabel.Text = DataRow("DescriptionofDefect").ToString Next End If End Sub
If I chose none, it stores data as "Null" If I Query the data as below, I don't get the data has value of "Null" SELECT tabale From type Where type <> STO or type <> ORD I get data that has empty string but not Null.
1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.
2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)

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 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 "".
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
I have pass following SQL Query to the through ObjectDataSource
[Code]....
And I am passing parameter through QueryString and My idea is like when empty string is pass it should show me all records but when I am passing empty string ObjectDataSource is making NULL and I am not getting desire result
