I'm pretty new to ASP.NET, building my first simple website using C#/RazorV2, hosting it on the free Windows Azure site.
I've found plenty of articles explaining how the URL structure works, and I've mostly got it figured out, but what I'm wondering is, what's the best/safest/most correct way of doing it?
Is it better to actually have multiple smaller files to handle things? Or is it "OK" or accepted to have one file handle several things?
For example, I'm building a simple blog web app, and right now I'm using single files to handle multiple sections, like I have a Blog.cshtml:
if (urlDepth > 0) {
renderPost = new List<BlogPost>();
switch (UrlData[0]) {
case "Post":
int _postID = 0;
_postID = Convert.ToInt32(UrlData[1]);
renderPost.Add(blogRender.ShowSinglePost(_postID));
Page.Title = renderPost[0].Name;
break;
case "Category":
BlogCategory selCat = catDisplay.GetCategory(UrlData[1]);
Page.Title = selCat.Name;
renderPost = blogRender.PostsInCategory(selCat.ID);
break;
}
} else {
renderPost = blogRender.MultiplePosts(10);
}
I know it's a bit crude as it is, but it's a work-in-progress, I plan on making it more failsafe as I go. But before I get too deep into it and possibly end up needing to tear it apart, would it be better to actually just make a folder named Blog, and have separate Post.cshtml and Category.cshtml files to handle their respective areas?
Figure it's best to know now so I can fix it if need be, rather than find out down the road that I messed up and have to try and pry apart the code.
If someone wants to see it in action to get a better idea of what I'm doing, it's currently at http://vouksh.azurewebsites.net/

IMO it is okay to handle differrent permission for the same thing, i.e. the admin can delete a blog post on the same page as a user can view blog posts.
I would not use the same page for Categories and blog posts because they are two different things.
The more features/things which can be display (categories, blog posts etc.) you add to a page the more crowded the pages' code behind gets and sooner or later you will loose the overview.

I have a checkboxlist populated by a datasource having a textbox as a controlparameter. The checkboxlist is located within a modalpopup. When I click the button, the checkboxlist shows the list pertaining to the previous select. If I close and click the button to show the modalpopup, the second click shows the updated checkboxlist. I've tried everything I can think of and nothing seems to work. The latest attempt is to have a dummy button (arcArcPat) for the modalpopup. I click on btnPrePat to get the dynamic checkbox, but no modalpopup appears. Of course, when I click on btnArcPat, everything's great because I've clicked on the btnPrePat first. I tried taking away the display:none; and then I only get a flash on the screen, nothing that stays. Help?
<pre lang="vb"><asp:Button ID="btnPrePat" runat="server" Text="pre arc" /><asp:Button ID="btnArcPat" runat="server" text="Search" />
<ajaxToolkit:ModalPopupExtender ID="mpePat" runat="server" TargetControlID="btnArcPat" PopupControlID="mpPat" DropShadow="true" BackgroundCssClass="modalBackground"></ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="mpPat" runat="server" CssClass="modalPopup" Style="display: none;">
<asp:CheckBoxList ID="cblPat" runat="server" RepeatDirection="Vertical" Font-Size="12px" />
<asp:Button ID="btnPatClose" runat="server" Text="Close" />
</asp:Panel>
Protected Sub btnPrePat_Click(sender As Object, e As EventArgs) Handles btnPrePat.Click
ds = New Data.DataSet
strSql = "SELECT TOP (100) PERCENT t.patID, myType FROM blah, blah"
da = New Data.SqlClient.SqlDataAdapter(strSql, cn)
Try
da.Fill(ds, "patSearch1")
If ds.Tables("patSearch1").Rows.Count > 0 Then
cblPat.DataSource = ds.Tables("patSearch1")
cblPat.DataTextField = ds.Tables("pat").Columns("myType").ToString
cblPat.DataValueField = ds.Tables("pat").Columns("patID").ToString
cblPat.DataBind()
End If
Catch ex As Exception
Response.Write(ex.ToString)
End Try
mpePat.Show()
End Sub
</pre>

For anyone else, - just wanted you to know that I figured out the bigger problem. Something must have corrupted the ajaxcontroltoolkit installation just enough. Once I re-referenced it, everything started working fine. Sorry for the trouble and thanks for your help.

<form id="MonthlyAward" action="@Url.Action("SubmitAwards", "MonthlyAward")" method="post">
@Html.DropDownListFor(m => m.ddlProjectsID, Model.ProjectNames, "--Select--", new { id = "ddlProjects",name="ddl_ProjectnameText", onchange = "document.getElementById('TheForm').submit();" })
how to get selected item text in form collection
[HttpPost]
public ActionResult SubmitAwards(FormCollection collection, MonthlyAwardModel award)
{
string strProjectId = collection["ddlProjectsID"].ToString().Trim();
return View();
|
|

There are two ways.
1. Have a hidden field in the page and set the value of that field as
$("#hiddendfield").val($("#ddlProjectsID option:selected").text());
You need to this on OnChange event of the dropdown. after that call the form submit method. it will be better if you use $.ajax of the jquery for submission.
Then in by using formcollection you can get the value of that hidden field in the controller.
2. have the list again in the controller and fire a query in that list against the id selected. now you have the selected item and you can get the display text

IMO the best way for using databindings in a ASP.NET web application is to start with MVC[^].

I m developing simple multiuser chat application in asp.net c# for my website.I have a table name chat in database.i have a chat.aspx.cs page which contains getmessage() addmessage() methods.i created 1 class file which contains getpreviousmsgcount() and newmsgcount() methods which returns the Count of total records in Chat table.now what i did is i drag two timers on my chat aspx page.
on timer1 tick event i retrieve prevmsgcount() and timer2 tick event i retrieve newmsgcount(),timer1 tick event get fired before timer 2.And in timer 2 i applied a following logic
if(newmgcount>prevmsgcount)
then refresh a page(so getmessage() gets called again and new messages are added).But in this case i observed timers keep on refreshing page on time interval."if" condition is getting ignored.how to ping sql server continously and track insertion of new record?is der any other way without using timer controls?
<b>Plz help with the code of C# and asp.net only.
Thanks in Advance.</b>

Can you be specific on what kind of help you seek?
You shared the colors of dates in a calendar, next you talk of having start-end date in red color, what does it mean?
What exactly are you trying to do? Where are you stuck specifically when you tried?

I am using Visual Studio 2012 C# ASP.NET on Windows 8 Virtual Machine. In the aspx page I am having below code :
<asp:TemplateField HeaderText="Active">
<FooterTemplate>
<asp:CheckBoxList ID="CheckBoxList2" runat="server">
<asp:ListItem>Act1</asp:ListItem>
<asp:ListItem>Act2</asp:ListItem>
<asp:ListItem>Act3</asp:ListItem>
</asp:CheckBoxList>
</FooterTemplate>
<ItemTemplate >
<asp:Label ID="Label7" runat="server" Text='<%# Eval("Active_Status") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate >
<asp:CheckBoxList ID="CheckBoxList2" runat="server">
<asp:ListItem>Act1</asp:ListItem>
<asp:ListItem>Act2</asp:ListItem>
<asp:ListItem>Act3</asp:ListItem>
</asp:CheckBoxList>
</EditItemTemplate>
</asp:TemplateField>
In the GridView1_RowDataBound I want to write the code for checked options of checkboxlist from database table column name Active_status; i.e. in the table I am storing values like "Act1,Act2,Act3" or "Act1" or "Act2, Act3" etc. So, as user clicks on Edit link button (i.e. putting Gridview in Editmode) the options of this checkboxlist should be checked marked respectively from table. Simultaneously, I wish to update the table as user changes the check option in the table something like "Act1,Act3" if user checked marked on Act1 and Act3 check options like wise in a single string column length 50.
I tried to search in google, but no luck. I am not sure, how clear I am asking the question, but if anything confusing or left by me, please let me know.
Thanks and Regards

Design the form. Then write the code to publish it.

This is fairly straight forward stuff. Try it and you should be able to do it.
Perhaps this blog engine could be useful for you. It has everything you need but the code syntax highlighting.
