I have a web project which includes two button in a view.when i click a button some textboxes along with that second button have to be visible.After entering data in textboxes,when i am trying to click the second button, its not working.What should i do to make it work?
I'm trying to learn the ropes of ASP.NET MVC and so far so good. One thing which I haven't seen addressed yet is the 'right' or most elegant way to pass multiple data models to a view. To help put the question in context, take this example: Say I was making a blog. When I log in I want the home screen to display a list of all new unapproved comments, as well as a list of recently registered users, and a list of the most recently submitted blog posts.
Most discussions I've seen suggest strongly-typing the view page so it can be called with something like "return View(RecentComments)" and iterate through the comments in the view, or to cast the data model like "var NewUsers = (MembershipUserCollection) ViewData.Model". What I'm ideally after is the 'right', or at least a 'right-enough', way of passing multiple models while still maintaining appropriate logic separation.
I am having a hard time solving the following with an MVC view. My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from a table called Retailers. I also have another table called RetailerCategories which stores the retailerid from the Retailers table and also a categoryid linking to a Category table. Note that there are multiple records for each retailerid in the RetailerCategories table.
In the view I want to show a list of retailers and with each retailer I want to show the list of categories applicable to them. What would be the best way to accomplish this?
So far I've seen demos of MVC that have simple pages, one for login, one for register, one for listing a table. In order to understand better the transition for WebForms developers into MVC patterns, I would like to understand how can I put together multiple CONTROLS (like the one provided by the default MVC project that VS2010 creates for us ...and make it work. OK so as an example, imagine we want to change the LogonUserControl.ascx to allow us to login (so to show UserName and Password textboxes and Logon button) from the Home Page.
1) We update the Control as follow:
2) We update the HomeController.cs file to handle the Logon Button Post event as follow:
We needed to move some code from AccountController to HomeController in order to get the control to work under the Index view. So ...with little luck it seems to work! Now the problem happens when you navigate to the Register view, considering that now we are not any longer on the HomeController "domain" but we are under AccountController. Register page shows perfectly and since the LogOnUserControl.ascx belongs to the MasterPage, it shows too. Since we are not logged yet, it will be displaying the UserName and Password textboxes. But we don't really care about that, because we are on the Register view and after populating the Register values, we click on the Register button. This is the error I get:
>>> To me that I come from the WebForms world, it seems like even if the event fired was the Register button (therefore under the AccountController domain), there is a kind of hidden OnInit event fired for any control on that view, in this case the Logon event. I'm sure this is NOT the case but the real question is... if we are allowed to have only one Controller x view, how can we put together controls that come from different "controller domains" and display them inside a single view?
Could I develop an eCommerce site using MVC that has the home page displaying different controls like [Most Purchased Product, Product of the Month, Special Promotions, Messages Inbox, Company Events ... and each control has it's own button to click and do something (so a proper POST request)] on the home page, unless I only have ONE single Controller which i'm not even sure if it will work or if it would make sense ....since MVC is all about separation of responsibilities.
protected void Button2_Click(object sender, EventArgs e) { String a = DropDownList1.SelectedItem.Value; String b = DropDownList3.SelectedItem.Value.PadLeft(3, '0'); String c = TextBox2.Text.PadLeft(5,'0').ToString(); String d = TextBox3.Text.ToString(); String digit = a+ b + c + d; try { myConn = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;"); myConn.Open(); //** string sql = "select * from testcase.main where reg_no =?"; //** OdbcCommand cmd = new OdbcCommand(sql, myConn); //** cmd.Parameters.AddWithValue("?", digit); MyReader = cmd.ExecuteReader(); //** while (MyReader.Read()) { String f = MyReader["pet_name"].ToString(); String g = MyReader["res_name"].ToString(); Label9.Visible = true; Label9.Text = f; Label10.Visible = true; Label10.Text = "VS"; //Label11.Visible = true; Label11.Text = g; } MyReader.Close(); } catch (Exception e1) { Response.Write(e1.ToString()); } finally { if (MyReader != null && !MyReader.IsClosed) { MyReader.Close(); } if (myConn != null && myConn.State == ConnectionState.Open) { myConn.Close(); } }
I want to add another sql query which is using two tables to fetch the data and than i want to display it in a dropdownlist after fetching data from database. How should i proceed?? Should i create a totally new connection? I tried many different ways like, creating new connection and new reader and entire try and catch block i coded again but on running the website i t was taking very long to load the contents. What i did i modified only this portion(below code) and used the entire try catch again but it dint work.
while (MyReader1.Read()) { String f = MyReader1["ret"].ToString(); DropDownList1.Items.Add(f); }
how to run multiple queries on a single button click. Actually I want whatever a user write in text box and click the button the text would get inserted in table category and also a table name project should get updated. I am using Sql server 2005 and c#
I am using two button click events and some required field validators . If I click the first button the fields in the other button also validates
I actually want to validate based on the button click if a first button is clicked only the fileds which are under button1 should validate not the fields which are in button2.
I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3) A CheckBox (Item4) A CheckBox (Item5) A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:
I have reffered the Select and Upload Multiple Files Gmail Style using JQuery and ASP.Net to upload multiple files but i want to upload files in button click. how can i call the code in button click because above mentioned article uploads the file using upload .ashx?

where i am supposed to accept an order from an vendor with multiple items.
i.e the form shoud accept one master record and multiple detail records and then either save all of them or discard all of them(both master and multiple detail records).
I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.

1.) What is the name of the OS process in which App Domain resides.
2.)if suppose There are Three Windows application hosted on a same envoirment and two instance is working for each application at a Time, means now total instance are six .what will happen among the below written cases :
a.) There will be six different app domain in a single OS process
b.) There will three app domain(one for each application) in a single OS process and some Parallel thread will be executed in each app domain for another instance.
c.) There will be Three OS process corresponding to each application.
3.) If eveything will remain same except there are three web application in place of windows in point 2, will there be any change in functioning.
