Java Script To Hide Column - Can't Use Code Behind?
Feb 9, 2010
I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added. Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?
As per my requirement, I am getting CompID, Company Name and URL from SQL database. I want to display just CompName and URL in gridvew. So, I need to hide the CompID in gridview. One way I can do BoundField field Visible to false but I need to retrive that compID id when user selected any of the row. if I set visible to false user wont see any compID in gridvew but I want access the selected compID also using SelectedRow.Cells[1].Text..
I want to test this code found here. It allows me to auto-load content from server as the user scrolls down the scroll down. I am having difficulties trying to convert code to C#/ASP.NET. Primarily, I want this code to be translated to C#/ASP.NET:
package com.vraa.demo; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class InfinitContentServlet extends HttpServlet { private static Integer counter = 1; protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter out = response.getWriter(); try { String resp = ""; for (int i = 1; i <= 10; i++) { resp += "<p><span>" + counter++ + "</span> This is the dynamic content served freshly from server</p>"; } out.write(resp); } finally { out.close(); } } @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } }
In addition, I would like to know if I have to make any changes to this JavaScript code:
I know how to register a client script that is on my web page, but I would like to know how to register my script when the script is in another file. Does anyone know how to register a file containing java script file. This is my code for calling the function when it's in the page.
I have a Java Script method that is called from an Aspx page named Default.aspx. The Java Script method is calledwhen a linked button on that page is pressed.
function Redir() { window.status=""; va urlGetit = "ConvertToExcel.aspx?" + "&test=" + 7; xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET",urlGetit,true) }
This Java Script method then calls my Code behind file named ConvertToExcel.aspx.cs" where I build an MS Excel file
i am having a application in which java script is must. but i am facing problem when at any client browser has java script disabled. i want a code using which i can check the browsers java script enabled/ disabled property so that the user cannot login until he enables javascript.
If I have a web form with a button control on it. Is their a way to have it's button press method called from a Java Script method? Can someone show me how to do this?I have a hidden button on a web form. I need to simulate it being pressed programatically through Java Script. So I need Java Script to run the code behind method for a button.
protected void PageButton_Click(object sender, EventArgs e) { // How to have this method called from Java Script? }
I am maintaining a website that has .Aspx web pages with no code behind C# files. This has been a challenge for me, because I need to do the following:
1.) When the page first loads, display a Java Script popup message box.
So how can I do this if I don not have a code behind C# file where I can check for isPostback in the on page load method? Can the on page load method be placed inline in the .aspx code? Anyway I need to figure out how to answer my question 1 above.
I need one common rounding function in asp.net and I will use that function in Java script, Code behind (.vb file) and SQL server (Stored Procedure). Is there any possible solutions in this requirement?
I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.
All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.
I need to hide a column but still read it's value. I have tried
visible=false gridview1.removeat(2) Cells.remove
But all of the above not only hide the column they also remove the data values. I see involve applying the CSS that hides the column but I can't use that trick since I am already applying a style to this column so once the value is be read it could be nicely formatted and shown in a dialogbox. Is there another way of hiding a column in a grid but still be able to read it's value? Note this is a dynamically built gridview in the code behind.
but it didn't work and gave me the following error:
Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.TemplateField does not have a DataBinding event.
I tried also to hide it programmatically, but seems I can't reach to the column by name (there's no name for TemplateField column).
I got asked to write a java application for my company. I'm a seasoned .Net developer so this is all new ground to me.My task is to produce an invoicing application that has several high level tasks such as:Build single invoiceBuild all invoicesMy company want to be able to call these tasks from a java console application - passing in relevant commands and parameters to invoke the tasks. They also want to be able to invoke the same code from an ASP.NET application.
how to hide the name of the requested column when i show the data in an ASP.Net web application. problem is: i request some data from a sql table and show it on an asp.net webpage. now it shows the data but adds the column name in front (both in Listview and DataList). Like this: Columname: Data. How do i avoid the columnname been shown?
