Call .js file in code behind

Question

Hi...

I have a .js file...

Name - myfile.js in the App_Themes/JS folder

How do I call this file from code - behind in c# asp.net ??

I need this file once the GridView is loaded...

Scenariao -

I have a button - "Load" on aspx page.
ON btn_click event, I have loaded the gridview with datatable.
After the gridview is loaded, I need to call this file..

How do I do that ??

I do not want to call it is aspx page.

Use this.. ScriptManager.RegisterClientScriptInclude( this, typeof(Page), "Enable-js", ResolveClientUrl("~/scripts/Enable.js")); ScriptManager.RegisterStartupScript( this, GetType(), Guid.NewGuid().ToString(), "Enable(True);", true);

Hi Upendra... Sorry For late reply.. This code also didnt work... I need column-heading in the side... But they are on the top... This is when the "Restore" button of Internet Explorer is clicked...

Hi... My .js file code is - var headertext = [], headers = document.querySelectorAll(".mytable th"), tablerows = document.querySelectorAll(".mytable th"), tablebody = document.querySelector(".mytable tbody"); for(var i = 0; i var current = headers[i]; headertext.push(current.textContent.replace(/?
|/, "")); } for (var i = 0, row; row = tablebody.rows[i]; i++) { for (var j = 0, col; col = row.cells[j]; j++) { col.setAttribute("data-th", headertext[j]); } } ------ This gives error on page_load if I call this on aspx page.

Hi, Add your Javascript file reference on your page. You can use this code on your Button Click event : System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append(@" "); sb.Append(@"YourJavascriptFunction();"); sb.Append(@" "); System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "JavaScriptCall", sb.ToString(), false);

Hi.. The purpose is not served dear.... In the file... the following lines are there - var Headers[] = , for(var i = 0; i for (var i = 0, row; row = tablebody.rows[i]; i++) ------------ It is for responsive gird view.... When I click the button, and restore the Internet Explorer , then column names must appear.. I am only getting values of rows...and not column names....

Try to do something like this: if(!this.Page.ClientScript.IsClientScriptIncludeRegistered("MyJS")) this.Page.ClientScript.RegisterClientScriptInclude("MyJS", ResolveClientUrl("~/JS/YourJScript.js"));
