In my repeater I have a float number that is shortened to a one decimal number (like 1,2 or 4,5 etc). It looks like this:
[Code]....
dt being my datatable containing the information shown on the page including my float number.
What's the code to make my label look like it does in the first example, with one decimal?

I have a button in my gridview recurring through the rows which requires confirmation before it deletes a record. Instead of it asking, "are you certain you want to delete this contact?" I want it to specifically ask the user, "are you sure you want to delete <the name of the contact>?" This is the button that I have at the moment and I have no idea how to place the contact's name in there:

I have a web app that I am developing at work. I need to be able to take input data and append a text file after (x) number of lines.
My web app is using asp.net with c#
how can i write a selector for specific column of GridView ?
i want to do something on mouseover of a GridView Column. and i want to do it once.
Here is my gridview :
<asp:GridView AutoGenerateColumns="False" Width="100%" ID="grvUsers" runat="server">
<Columns>
<asp:TemplateField HeaderText="Delete">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# eval("ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Html Output :
<table cellspacing="0" rules="all" border="1" id="grvUsers" style="width:100%;border-collapse:collapse;">
<tr>
<th scope="col">Delete</th>
</tr><tr>
<td>
<span id="grvUsers_Label1_0">23</span>
</td>
</tr>
</table>
GridView DataBound
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dr As DataRow
Dim dt As New DataTable
dt.Columns.Add("id")
dr = dt.NewRow
dr(0) = "23"
dt.Rows.Add(dr)
grvUsers.DataSource = dt
grvUsers.DataBind()
End Sub
Normally I work in ASP Classic, and am still a bit green on ASP.Net MVC.
I have my model with its fields or entities (might not be the right word hence why not able to find if previously answered, forgive me), and some of these will have null values such as hyperlinks, email address, specific types of phone numbers, etc.
What I want to do is not write certain blocks of HTML within the foreach loop if a field is empty.
In ASP Classic, I would have written an If statement along the lines of:
<% If RS.field <> NULL then %>HTML with <%=RS.field %><% End If %>
<% If RS.field2 <> NULL then %>HTML with <%=RS.field2 %><% End If %>
...
However, I don't know how to achieve the same result in ASP.Net MVC.In one of my current usages, a list of sellers returned for a specific set of search results, it runs through a foreach loop and returns the current HTML (in part):
Website: <a class="url" href="<%= seller.ContactWebsite %>" target="_blank" title="Visit the website for <%= seller.Name %>"><%= seller.ContactWebsite %></a><br />
So, if for example I have a field from the model, say seller.ContactWebsite, and this field was NULL, I would not want it to write this as part of the foreach loop.
Im trying to find out how to transform euro symbolto UTF-8 Format.
What does this even look like ?
Ideally I would like to go
String.Replace("€","UTF-8 Symbol for Euro")
I've been googling for a while now and for the life of me can't seem to find a solution. I thought this would be easy but it's taking too long and am turning to stackoverflow.
I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:
DateTime.ParseExact(startTime,"MM/dd/yyyy hh:mmtt", null);
I am searching for a way to resize and crop images to a specific size in a fixed ratio like 16:9. So I have any image and any size and it should be resized and cropped in a ratio 16:9.
Just cropping is not very nice. I want that the image is resized more and if necessary maybe cropped. Or better: I want to reuse as much as possible from the original image but resize and crop it centered so I could use it in a fixed html div with a ration of 16:9.
how can i write a sql to execute the file at specific time sql server database.

Here is the website situation:
Webpage A: look & feel alignments are in the central of the screen. It has a submit button. The last code in the submit command() is this message subject:
Response.Write(string.Format("<script>window.open('{0}', '_blank');</script>", url));
where url = another webpage B.The outcome is fine. Webpage B is populated properly. However, Webpage A postback as aligment to the left, it is no longer the center. I could not find a way to debug the issue.

I have a problem that I have to enter float values in my database from a textbox. The problem is I want to enter only float values upto two decimal places(like 12.34, 56.78, etc). How do I do this.? Do I need to first convert the values from my textbox (string values) to Int64 before submitting?
My second problem is that I have to compare that float value in my database to a value in another text box. I am using this sort of code:
[Code]....
<div id="nav-main" align="center" style="width: 95%; height: 35px;">
<div style="float:left; height: 29px; width: 260px;">
<a href="javascript:void(0);" onclick="select();"

I have a strange problem with some float values that I pass to an Insert Query.
Example : If I pass in float value "1.4", the value stored in the Database is "1.399999976158141". The DataColumn is of type float.
I pass the float values as parameters to the query using "AddwithValue".
