    <p><em>Edit: I may have misunderstood your question. If you're wondering how to remembering the selected options after submitting it to the server, this answer doesn't cover that.</em></p> <p>When changing between buy and rent, keep tabs on what was selected before the change. When you change back, use this information to set the dropdown's <code>selectedIndex</code> property.</p> <p>Example: </p> <ol> <li>You have selected buy and selected min = 100 and max = 200.</li> <li>You change from buy to sell. Now lastMin = 100 and lastMax = 200</li> <li>You change back to buy. You know that the last values were 100 and 200, so you set the dropdowns' values accordingly</li> </ol> <p>I made a demo of it in practice here: <a href="http://jsfiddle.net/VUBQL/" rel="nofollow">http://jsfiddle.net/VUBQL/</a> . The code is as follows</p> <pre><code>var lastSelectedIndexes = { min: -1, max: -1 }; //The callback function when BuyRent changes function buyRentChanged() { var maxPrice = document.SearchForm.MaxPrice; var minPrice = document.SearchForm.MinPrice; //Save currently selected indexes var selectedIndexes = { min: minPrice.selectedIndex, max: maxPrice.selectedIndex }; var BuyRent = this.value if (BuyRent=='buy') { maxPrice.options[0] = new Option("Price (Max)","150000000"); maxPrice.options[1] = new Option("\u00A3100,000","100000"); maxPrice.options[2] = new Option("\u00A3200,000","200000"); minPrice.options[0] = new Option("Price (Min)","0"); minPrice.options[1] = new Option("\u00A3100,000","100000"); minPrice.options[2] = new Option("\u00A3200,000","200000"); } else if (BuyRent=='rent') { maxPrice.options[0]=new Option ("Price (Max)","9999999"); maxPrice.options[1]=new Option("\u00A3250","250"); maxPrice.options[2]=new Option("\u00A3500","500"); minPrice.options[0]=new Option("Price (Min)","0"); minPrice.options[1]=new Option("\u00A3250","250"); minPrice.options[2]=new Option("\u00A3500","500"); } //Set selected index to the last selected index, if it was set if (lastSelectedIndexes.min !== -1) minPrice.selectedIndex = lastSelectedIndexes.min; if (lastSelectedIndexes.max !== -1) maxPrice.selectedIndex = lastSelectedIndexes.max; //Save the current indexes lastSelectedIndexes.max = selectedIndexes.max; lastSelectedIndexes.min = selectedIndexes.min; } var radioBoxes = document.SearchForm.BuyRent radioBoxes[0].onchange = buyRentChanged; radioBoxes[1].onchange = buyRentChanged; </code></pre>

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.
