Hi to All,
I am planning to create a new web site in my free times. So that I can learn, in a productive way.
Now, since I am a beginner in ASP.NET (I have worked on VB.NET earlier)....I need certain help in starting up the project.
What I mean is, like certain points or tips or tricks or measures , we need to take care in initial point of doing any project....Please advice me those,if any, in ASP.NET projects...or point me out those places where I need to take care of it initially, so that later on I needn't to Re-Do everything, for any kind of change.
Example: say for scalability of the project, I need to beak my project in modules, so that any change can be updated easily....something like that...
Thanks in advance.

You'd do well to work out what parts of your page will appear on all pages, and put them in a master page. Then as you create parts of pages, you'd do well to consider controls that might appear on more than one page, and create them as user controls. You'd also do well to create your own base page class, which will give you access to things you commonly use. The first thing I add to such a base class, is access to a strongly typed version of the master page.

I don't think there are any. Just use whichever language you feel comfortable with, as both are fully supported in ASP.NET.

As someone else said, VB.NET and C# both compile to the same intermediate language. There's no reason to choose one over the other, except personal preference. In ASP.NET you can actually write some pages in one and some in the other, if you wanted to, but I don't recommend it. Just use what you are comfortable with.

That's an excellent tip, Christian. I'll use it myself. But could you clarify what you mean by "access to a strongly typed version of the master page?" Specifically, what makes a Master Page "strongly typed?"

You could use regular expressions to do this.

Use the WebBrowser control that comes with .NET. You can use the WebBrowser.Document.Images collection to get the list of image tags in the html page.
WebBrowse1.Navigate("c:\mypage.html");
List<string> images = new List<string>();
HtmlElementCollection elements = WebBrowser1.Document.Images;
foreach(HtmlElement e in elements) {
images.Add(e.Attributes("id");
}

I tried paging in ASPNET. My code get the lists from the database using stored procedure with entire records. Then, according to the number of pages, the page number should be displayed. I need only limited number of page numbers to be shown in a page.
When, I click next button, next set of page number should be displayed. My stored procedure will return dataset.
This is my code for Paging..
private void doPaging()
{
DataTable dt = new DataTable();
dt.Columns.Add("PageIndex");
dt.Columns.Add("PageText");
for (int i = 0; i <= totalpage; i++)
{
DataRow dr = dt.NewRow();
dr[0] = i;
dr[1] = i + 1;
dt.Rows.Add(dr);
}
dlPaging.DataSource = dt;
dlPaging.DataBind();
}
This code will display all page numbers once in a page.. Instead I need only 5 page numbers should display once. When I click next button, next 5 page numbers should be displayed

This is messy. Why do you need a datasource made up of a data table to do this ? A List of numbers is a viable data source. Of course, you're stepping from 0 to the number of pages, you need to change the code to only loop through the numbers you want to show. That seems obvious to me.

Wat abt remaining numbers? How should I use that?
|
|
|
|

I don't understand. You said you wanted to only show 5 numbers, so I said then write code to only show those.

This is an IE bug. You should look at menu controls that already exist, and how they do it. There's one built in to ASP.NET.

Thanks Christian Graus.
Now I Tried that control in ASP.NET Webpage. It is working properly in IE. and I used Same code block.
But I copied same code and component, & I tried in User-controller but same problem is coming.
How can I come out from this Problem
or Is any alternative way is there???

OK, the issue is probably to do with what's in your user control. At the end of the day, it's a bug in IE, I've come across it, but I just found another control that didn't do it, I don't know what the actual workaround is.

Hi all,
I'm developing an ASP.Net app with C#. I have a Gridview that I want to show right on page load. I'm then capturing data into the textboxes and need to save it on the gridview right after clicking ADD button.
I can't get my Gridview displayed on page load and when saving the data from the textboxes to the Gridview I get this error:
"Column ‘Full Names’ does not belong to table"
This is what I've got in my code
html Design:
<asp:gridview id="dgInfoProfile1" runat="server" autogeneratecolumns="False">
<columns>
<asp:templatefield headertext="Full Names">
<asp:templatefield headertext="Identifying Number">
<asp:templatefield headertext="Passport Number">
Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();
}
ADD button:
protected void brtAdd_Click(object sender, EventArgs e)
{
try
{
DataRow dr = dt.NewRow();
dr["Full Names"] = txtFirstName3.Text;
dr["Identifying Number"] = txtIdentityNo.Text;
dr["Passport Number"] = txtPassportNo.Text;
dt.Rows.Add(dr);
//Bind GridView Here with this Table
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
I'm not sure where I've missed it, your advice and help in this is highly appreciated.
Thanks.

Welcome to correct forum. 
Nopo wrote: DataRow dr = dt.NewRow();
How come this line is not showing any error. 
You have to put
Nopo wrote: DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
in ADD button click.
Just leave GridView.DataBind() in PageLoad.

I have put:
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
under ADD button click and now my ADD button click looks like:
DataTable dt = new DataTable();
DataRow dr = new DataRow();
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
dr["Full Names"] = txtFirstName3.Text;
dr["Identifying Number"] = txtIdentityNo.Text;
dr["Passport Number"] = txtPassportNo.Text;
dt.Rows.Add(dr);
//Bind GridView Here with this Table
this.dgInfoProfile1.DataSource = dt;
dgInfoProfile1.DataBind();
Now, the app is complaining with this line:
DataRow dr = new DataRow(); 
error: 'System.Data.DataRow.DataRow(System.Data.DataRowBuilder)' is inaccessible due to its protection level
How am I supposed to define the DataRow?
And as for the gridview on PageLoad, it's not showing still.

Why are you doinh this.
1. Create DataTable.
2. Assign Columns to it.
3. Create a DataRow by dt.NewRow().
4. Fill that row and add it to datatable.
