    <p>I want to test the C# code side when user click the button, the method in C# function should be able to call the JavaScript function to show alert C# public variable results. Somehow it doesn't call anything at all. At the bottom of <code>ButtonRequest_Click</code> function, I wrote <code>Page.ClientScript.RegisterStartupScript(this.GetType(), "CreateIsm();", "CreateIsm();", true);</code> to call <code>CreateIsm();</code> function in JavaScript. Maybe this doesn't work?</p> <p>Here is C# codes,</p> <pre><code>public Collection&lt;PSObject&gt; output = new Collection&lt;PSObject&gt;(); public string deviceName = ""; public string ipAddresses = ""; public string YourScript = ""; protected void ButtonRequest_Click(object sender, EventArgs e) { deviceName = string.Empty; ipAddresses = string.Empty; HiddenName.Visible = false; string str = ""; string ipAddress = ""; string name = ""; var tbids = (List&lt;string&gt;)Session["tbids"]; //create a powershell Runspace runSpace = RunspaceFactory.CreateRunspace(); runSpace.Open(); RunspaceInvoke invoke = new RunspaceInvoke(); Pipeline pipeline = runSpace.CreatePipeline(); Command invokeScript = new Command("Invoke-Command"); //Add powershell script file and arguments into scriptblock ScriptBlock sb = invoke.Invoke(@"{D:\Scripts\Get-FreeAddress.ps1 '" + DropDownListContainer.SelectedValue + "' " + DropDownListIP.SelectedValue + "}")[0].BaseObject as ScriptBlock; invokeScript.Parameters.Add("scriptBlock", sb); invokeScript.Parameters.Add("computername", TextBoxServer.Text); pipeline.Commands.Add(invokeScript); Collection&lt;PSObject&gt; output = pipeline.Invoke(); runSpace.Close(); Runspace runSpace2 = RunspaceFactory.CreateRunspace(); runSpace2.Open(); foreach(PSObject psObject in output) { ipAddress = "" + psObject; ipAddresses += "" + psObject; foreach(var id in tbids) try { name = Request[id]; deviceName += Request[id] + "\r\n"; Pipeline pipeline2 = runSpace2.CreatePipeline(); Command invokeScript2 = new Command("Invoke-Command"); //Add powershell script file and arguments into scriptblock ScriptBlock sb2 = invoke.Invoke(@"{D:\Scripts\Set-IPAddress.ps1 " + ipAddress + " " + name + "}")[0].BaseObject as ScriptBlock; invokeScript2.Parameters.Add("scriptBlock", sb2); invokeScript2.Parameters.Add("computername", TextBoxServer.Text); pipeline2.Commands.Add(invokeScript2); tbids.RemoveAt(0); Collection&lt;PSObject&gt; output2 = pipeline2.Invoke(); foreach(PSObject psObject2 in output2) { str = str + psObject2; } break; } catch { } } Page.ClientScript.RegisterStartupScript(this.GetType(), "CreateIsm();", "CreateIsm();", true); } </code></pre> <p>Javascript on aspx side in html,</p> <pre><code>&lt;%@ Page Title="Home Page" Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" CodeBehind="~/Default.aspx.cs" Inherits="_Default" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head id="Head1" runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.2.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script&gt; CreateIsm = function (funct) { alert('&lt;%=ipAddresses%&gt;'); alert('&lt;%=deviceName%&gt;'); }; &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; //the are html codes here but I cut it off except ButtonRequest &lt;asp:Button ID="ButtonRequest" runat="server" Text="Request" Visible="False" onclick="ButtonRequest_Click" /&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    3. COWhen somebody clicks the button, its too late to register a startup script--the page has already loaded. `Page.ClientScript.RegisterStartupScript` runs just fine, but the hook it creates never gets called by the browser

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.

SQuiL has stopped working due to an internal error.

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