Call Jquery Code From Code Behind

Hi,

The ClientScriptManager.RegisterStartupScript method allows you to inject at client JS when the page postback. Is that what you would like to achieve?

Here is a sample process of how it is being used in the form designer. You can open the Form / .NET tabs to view the code behind I have added.

Form / .NET / Code Behind

	// Place here your ASP.NET procedures and global variables.
	// It will be declared within a <script runat="server"> block,
	// and placed before the opening <html>.
	// Do not include the <script runat="server"> tag.
	// Use the Control key + Spacebar to show the keywords list.

	protected void Page_Load(object sender, EventArgs e)
	{
	    base.Page_Load(sender, e);
	    
	    // Define the name and type of the client scripts on the page.
        String csname1 = "PopupScript1";
        Type cstype = this.GetType();
            
        // Get a ClientScriptManager reference from the Page class.
        ClientScriptManager cs = Page.ClientScript;
    
        // Check to see if the startup script is already registered.
        if (!cs.IsStartupScriptRegistered(cstype, csname1))
        {
            StringBuilder cstext1 = new StringBuilder();
            cstext1.Append("<script type=text/javascript> alert('JS injected at Page_Load') </");
            cstext1.Append("script>");
    
            cs.RegisterStartupScript(cstype, csname1, cstext1.ToString());
        }
	}

    protected void REQUEST_BUTTON1_Click(object sender, EventArgs e) 
    {
        // Define the name and type of the client scripts on the page.
        String csname1 = "PopupScript2";
        Type cstype = this.GetType();
            
        // Get a ClientScriptManager reference from the Page class.
        ClientScriptManager cs = Page.ClientScript;
    
        // Check to see if the startup script is already registered.
        if (!cs.IsStartupScriptRegistered(cstype, csname1))
        {
            StringBuilder cstext1 = new StringBuilder();
            cstext1.Append("<script type=text/javascript> alert('JS injected on custom button click event') </");
            cstext1.Append("script>");
    
            cs.RegisterStartupScript(cstype, csname1, cstext1.ToString());
        }
    }
