The line break is there - if you load it back into a multi-line text box you'll see it just the same as entered in the first place - but to displayt it on a web-page you need to replace all the line breaks with <br> tags... in VB this would be:
supposing your databse field is returned to a string s:
s.Replace(vbCrLf, "<br>")
Can't help you with the C# equivalent, but the carriage-return line-feed characters are Chr(13) adn Chr(10) respectively...

Hi,
my question is this:
Is it possible to know if my site is running on IIS or on Web Development Server at runtime from code behind?
The only solution that I found is to check the process name, but...
Thanks

You can check the Response.headers to see if it sis running on IIS or not.and of course its version as well.
In ASP.Net this is available through Response.Headers variable

var gridViewCtlId = '<%=gridview1.ClientID%>';
var gridViewCtl = null;
var curSelRow = null;
var curRowIdx = -1;
function getGridViewControl()
{
if (null == gridViewCtl)
{
gridViewCtl = document.getElementById(gridViewCtlId);
}
}
function onGridViewRowSelected(rowIdx)
{
var selRow = getSelectedRow(rowIdx);
if (null != selRow)
{
curSelRow = selRow;
var cellValue = getCellValue(rowIdx, 0);
alert(cellValue);
}
}
function getSelectedRow(rowIdx)
{
return getGridRow(rowIdx);
}
function getGridRow(rowIdx)
{
getGridViewControl();
if (null != gridViewCtl)
{
return gridViewCtl.rows[rowIdx];
}
return null;
}
function getGridColumn(rowIdx, colIdx)
{
var gridRow = getGridRow(rowIdx);
if (null != gridRow)
{
return gridRow.cells[colIdx];
}
return null;
}
function getCellValue(rowIdx, colIdx)
{
var gridCell = getGridColumn(rowIdx, colIdx);
if (null != gridCell)
{
alert(gridViewCtlId)
return gridCell.innerText;
}
return null;
}
I i call it as:
For Each row As GridViewRow In GridView1.Rows
CType(row.FindControl("Textbox1"), TextBox).Attributes("onclick") = "javascript: return getCellValue(0,1)"
it works...
But how to pass dynamic value in place of 0 and 1
<div class="ForumSig">sanjay kumar samantaray</div>

What dynamic values do you want to pass instead of 0 and 1? Please be more specific when phrasing a question.
If the first argument to your javascript function needs to change with each iteration of the loop, get the index of the current row by referencing the RowIndex property of your row object and insert it into your attribute string. For instance:
CType(row.FindControl("Textbox1"), TextBox).Attributes("onclick") = "javascript: return getCellValue(" + row.RowIndex.ToString() + ",1)"
Do something similar if you need to change the column index dynamically.

Have a look at the HTML generated by your page. Are the javascript event handlers being generated correctly?

Hi,
I want to retreive the user id of the person who visits the page created by me. Till now I was using the System.Identity.Name method to retreive user id of the person. But this gives me the user id of the person who is logged in the system.It didnt give me any worries since I was using VS in my machine. Now when I try to run the page from IE of other machine it is giving error which says Input string was not in a correct format. I am including the codeline where it is giving error.
txtid.Text = Right(User.Identity.Name, 6)
Dim sconnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Mypath\DW\DW.mdb;User ID=Admin; Password="
Dim dbcon As New OleDbConnection(sconnection)
Dim myCommand = New OleDbCommand("Select associate_id from dwbi", dbcon)
Dim dr As OleDbDataReader
dbcon.Open()
dr = myCommand.ExecuteReader()
While (dr.Read())
MsgBox("textid.text")
If dr("associate_id") = txtid.Text Then 'This is where error is pointing
Response.Redirect("Update.aspx")
End If
End While
dr.Close()
dbcon.Close()
End If
End Sub
It is gving the error which says "Input string was not in a correct format"

Iterate through the child nodes of the selected node.
Paul
|
|
|
|

i just used a sample code
var selNode = tree.getTreeNode(tree.selectedNodeIndex);
for(var nodeCount = 0; nodeCount < selNode.getChildren().length; nodeCount++)
{
var chldNode = selNode.getChildren(String(nodeCount));
alert(chldNode[nodeCount].getAttribute('ID'));
alert(chldNode[nodeCount].getAttribute('Text'));
}
in this, alert(chldNode[nodeCount].getAttribute('ID')); is working but alert(chldNode[nodeCount].getAttribute('Text')); is not working. is there any error?..

The attribute names are case-sensitive. Try 'text' instead of 'Text'.

We don`t do spoon feeding here. Why don`t you first read some books.Don`t try to just copy the code, understanding is all that matters.
When you fail to plan, you are planning to fail.

As a starting point you can take a look at my article about sorting: ASP.NET GridView Sort Indicator Component
To add Add, Update, Delete you can extend this sample, the base concepts with GridView - ObjectDataSource stays the same.

Hi friends
i want to create a web application which should look like windows application.
Plz let me know what shoul i do?
D.Willington

What do you mean by "look like windows application"?
Because:
- not all types of usercontrols that are possible within a windows forms application are possible on a web application (FileOpen dialog, FileSave dialog, hierarchical GridViews, multicolumn DropDownLists, ...)
- you will always have the browser window as a host window
- HTML is very limiting in layouting compared to a windows forms/WPF application.
Silverlight might though be an alternative in the near future.

A very rich look is achieved through developing an ActiveX Control and bringing it on the webpage. Otherwise, there is a distinct line of demarcation between the web platform and the windows desktop.

Dont create DropdownList at runtime
place it in EditItemTemplate instead of TextBox
Find out it on RowDataBound Event of Gridview and bind it with datas
