    <p>I have a textbox with a live search function. It is working all good except one problem. If I type any characters on it, it just loses its focus. If I set textbox.Focus(), the cursor goes at the beginning of the textbox.</p> <p>I have tried most of solutions on the internet. Please check my codes below.</p> <pre><code>asp:TextBox ID="searchCompany" runat="server" Text="" CssClass="searchCompany" AutoPostBack="true" Width="190px" OnTextChanged="searchCompany_TextChanged"&gt;&lt;/asp:TextBox&gt; </code></pre> <p>In page_Load</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { //ScriptManager1.RegisterAsyncPostBackControl(Menu1); menuDisplay(); searchCompany.Attributes.Add("onkeyup", "setTimeout('__doPostBack(\\'" + searchCompany.UniqueID + "\\',\\'\\')', 0);"); //searchCompany.Attributes.Add("onfocus", "javascript:setSelectionRange('" + "','')"); //searchCompany.Focus(); } </code></pre> <p>and I have tried javascript as below</p> <pre><code>&lt;script type="text/javascript"&gt; function setSelectionRange() { var inputField = document.getElementById('searchCompany'); if (inputField != null &amp;&amp; inputField.value.length &gt; 0) { if (inputField.createTextRange) { var FieldRange = inputField.createTextRange(); FieldRange.moveStart('character',inputField.value.length); FieldRange.collapse(); FieldRange.select(); } } } &lt;/script&gt; </code></pre> <p>I have tried to put codes on a method "searchCompany_TextChanged" which is calling if user type any characters on a textbox everytime however it is not working as well.</p> <p>I saw other solutions with using Textbox.Select() but System.Windows.Control is not working in asp.net i guess.</p> <p>Any idea??</p>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
