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.

Thanks. Here it is now:
//Create DataTable.
DataTable dt = new DataTable();
//Assign Columns to it.
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
//Create a DataRow by dt.NewRow().
DataRow dr = dt.NewRow();
//Fill that row and add it to datatable.
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();
I'm making a huge progress now.
After clicking ADD button, the gridview is showing with all the column names but the data captured from the textboxes is not being saved to the gridview.
I'll double check and see if there're any typing errors.

sure, tell me if it works.

Its now working perfect.  I think the problem was that I turned the AutoGenerateColumns to "false" because after changing it to "true" it worked.
Thanks a lot for all the guidance you've given me.
