How do I save and display in the same format (including the witespaces, linefeeds, etc?
Thanks you all!

An easy way would be to use the AjaxControlToolkit HtmlEditor[^]. Save the resultant data to the database and view back in the editor or a label as required. You'll need to encode the data (see here to get started: HttpServerUtility..::.HtmlEncode[^]. You can display the data by reversing the process.Tychotics: take us back to the moon

You can refer to the following code:
public int ExportToExcel(DataTable schemaTable, string tableName, string filePath, DataTable source)
{
string connString = "Provider = Microsoft.Jet.OLEDB.4.0 ;Persist Security Info=False; Data Source = " + filePath + ";Extended Properties=Excel 8.0;";//'HDR=Yes;IMEX=1";
if(System.IO.File.Exists(filePath))
{
System.IO.File.Delete(filePath);
}
string create = "Create Table [";
create += tableName;
create += "] (";
string sourceColumn = "(";
foreach(DataRow dr in schemaTable.Rows)
{
string columnName = dr["ColumnName"].ToString();
//create string
create += "[";
create += columnName;
create += "]";
sourceColumn += "[" + columnName + "],";
string type = dr["DataType"].ToString();
switch(type)
{
case "System.Int32":
case "System.Int16":
case "System.Int64":
case "System.UInt32":
case "System.UInt16":
case "System.UInt64":
create += " INTEGER NULL,";
break;
case "System.Decimal":
case "System.Double":
case "System.Single":
create += " numeric NULL,";
break;
case "System.DateTime":
create += " datetime NULL,";
break;
case "System.Boolean":
create += " BINARY NULL,";
break;
default:
create += " varchar(";
create += dr["ColumnSize"].ToString();
create += ") NULL,";
break;
}
}
create = create.Substring(0, create.Length - 1);
create += ")";
using(OleDbConnection conn = new OleDbConnection(connString))
{
conn.Open();
using(OleDbTransaction trans = conn.BeginTransaction())
{
try
{
OleDbHelper.ExecuteNonQuery(trans, create);//create table
string insertHead = "Insert Into [" + tableName + "]" + sourceColumn.Substring(0, sourceColumn.Length - 1) + ") Values";
int result = 0;
foreach(DataRow dr in source.Rows)
{
string valueStr = "(";
for(int j = 0; j < source.Columns.Count; j++)
{
if(source.Columns[j].DataType == typeof(System.String))
{
valueStr += "'" + dr[j].ToString().Replace("'", "’") + "',";
}
else if(source.Columns[j].DataType == typeof(System.DateTime))
{
string date = dr[j].ToString();
if(date == string.Empty)
{
valueStr += "null,";
}
else
{
valueStr += "'" + date + "',";
}
}
else
{
valueStr += dr[j].ToString() + ",";
}
}
string insert = insertHead + valueStr.Substring(0, valueStr.Length - 1) + ")";
result += OleDbHelper.ExecuteNonQuery(trans, insert);
}
trans.Commit();
return result;
}
catch
{
trans.Rollback();
throw;
}
}
}

I am using Visual Studio Web Developer 2008, CSS 2.1
Browser Firefox 3.5.8, IE 6.0.2900
I am trying to add this menu described here
[], but it is causing all the master page components to change positions.
I created a master page following tutorials elsewhere and the problem mainly comes with the Menu bar, I created a custom menu bar to suit my needs, rather than using the inbuilt menu, but i am guessing because of the menu the webpage components are out of place in
1)Firefox: there is a Nav div on the left hand side of the page
Structure of intended webpage
------------------------------
Logo Title
Dotted Line
Menu
Dotted Line
Nav Main Content page
(25%) (margin-left:30%;)
footer
This is how i am trying to arrange the page but in firefox the Nav falls to the right, CSS setting justify:left dosent help.
2)In Internet Explorer
The menu appears vertical rather than horizontal
Please find the code to my Master Page below, however note that i am NOT trying to use the asp:menu item for a menu, and using a customized menu. Because of which my master page is all over the browser.
I would really appreciate if anyone can provide any sort of suggestions.

When i assign the html table to the hiddenfield value using javascript i am getting the error like this:
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$hd2="<TBODY>
<TR>
<TD c...")."
I used the javascript function like this:
var element = document.getElementById("aspnetForm");
var store1 = document.getElementById("tb1");
document.getElementById("ctl00_ContentPlaceHolder1_hd2").value = store1.innerHTML.toString();
Help me how to solve this

Having angular braces "<" with in a text box, hidden field, text area, etc., triggers this error during server post. ASP.NET engine thinks that malicious code has been injected into the request stream and stops processing the request and raises this error, when it encounters such a situation.
To over come this, either replace the angular braces with their HTML code "<" - & l t ; ">" - & g t ; [with out the spaces] or else set ValidateRequest="false" on the page directive of the page.
This web page has examples for both solutions Allowing HTML Formatted User Input in ASP.NET [^]
NOTE: The later would make your page susceptible to injection attacks.

Hello Friends,
Recently i have tried to load a excel data into a data table.But when it load data into data table some of cell of data table left blank.But there have data into excel cells.I have not found any special character in those cell.I made column format into text.
|
|

Excel by default has a very loose type binding, i.e. if you set the column's formatting to text and insert a numeric value in it then it treats the data as text. When you set the format to numeric and enter textual data it changes the type to general which accepts all data values.
Now, Datatables in ADO.NET are type sensitive and are tight binding. When you execute a query against a cell range in excel .NET sets the datatype of the column as the data type of the first cell in that column in excel. Now if there is data of other type in that row then that data is ignored when reading the cells and is left as NULL in the data table.
As far as I know the cell formatting does not matter, the ADO.NET engine analyzes the data in the first cell and sets the data type. You cannot control the way it is done. So, if you have text data and numeric data in the same column then make sure that the fist row has text data than numeric data.
HTH!
