    <h2>String.Length</h2> <p>Returns the length of the string (number of characters).</p> <p><strong>C#</strong></p> <pre><code>string MyString = "Stack Overflow String"; Response.Write(MyString.Length); </code></pre> <p><strong>VB.net</strong></p> <pre><code>Dim MyString As String = "Stack Overflow String" Response.Write(MyString.Length); </code></pre> <p><strong>MSDN Reference</strong></p> <p><a href="http://msdn.microsoft.com/en-us/library/system.string.length.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.string.length.aspx</a></p> <h2>Physical String Size Serverside</h2> <blockquote> <p>I'm not sure why so many people are apparently determined to put forward the idea that it is 'flat out impossible' to do this server side, it isn't. You just need to be a little bit creative, and be willing to do a lot of testing.</p> </blockquote> <p>There is no native function I know of to measure the pixel dimensions of a string. You can achieve it in the following ways. Note you need to know:</p> <ul> <li>The font family</li> <li>Font size</li> <li>Container dimensions (for when the text wraps lines)</li> <li>Any other CSS rules such as word spacing are going to make the calculation a lot less accurate and more complex. Try and avoid it if accuracy is important.</li> </ul> <p><strong>1. Render it to an image and measure image size</strong></p> <p>Draw the text to a bitmap, and then measure it. This should be reasonably exact.</p> <p><strong>2. Use a fixed width font</strong></p> <p>If you are using a fixed width font and the text doesn't wrap, you can simply multiply its width by the number of characters.</p> <p><strong>3. Rough estimation</strong></p> <p>You could get a reasonably rough estimation on non fixed width fonts by picking some arbitrary character width number and multiplying it by total characters. Depends how accurate you want to be. </p>

    1. COi tried that before however i then have to mulitply that by an average pixel width for a text character which is a little bit sketchy.

    2. COfyi the client has control and can override and throw all these calculations off. The only sure way is to render into a temporary span and use client functions to measure that.

    3. CO@Asawyer, and what if the client has Javascript disabled? You have to make a compromise at some point. If the font is specified as being 12px and Courier New, you can pretty much safely assume that is how it is going to be rendered. He asked for a server side solution specifically, that is what I have tried to provide him with.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
