Hello!
I'm kinda new to ASP.net so i am just testing and failing, so maybe the approach i am going for is just wrong if so tell me =)
I'm trying to print a sequence of HTML code with Response.Write ... works fine enough, but i am interested in printing this code at a specific point on the page...
Currently i am trying to do that from the class with the method Page_Load, with the event of a button click...
Don't know if that explain it..

Put a literal control on the area where you need it to be printed. Set the HTML code to literal's Text property.

Hi all,
I have one doubt, i am fetching data from database and i am displaying data in gridview.(select empid,empno,covert(varchar,dateofbith,101),convert(varchar,joiningdate,101) from emptable) (values are:1,12,'12/31/1986','12/31/2008')
i am not using any boundfields in gridview.
i am using this code to sort the gridview columns,everything is working fine but dateofbirth,joiningdate fields sorting is not working .
i am using below code to sort the gridview columns:
If Not (Page.IsPostBack) Then
ViewState("Sort") = "asc"
end if
and
Protected Sub grdCommon_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles grdCommon.Sorting
Try
grdCommon.DataSource = Session("grdCommon")
grdCommon.DataBind()
Dim dataTable As DataTable = CType(grdCommon.DataSource, DataTable) ' DirectCast(ViewState("grdCommon.DataSource"), DataTable)
Dim dataView As DataView = New DataView(dataTable)
If Not (dataView Is Nothing) Then
If ViewState("Sort").ToString() = " asc" Then
ViewState("Sort") = " desc"
Else
ViewState("Sort") = " asc"
End If
dataView.Sort = e.SortExpression + ViewState("Sort").ToString()
grdCommon.DataSource = dataView
ViewState("grdCommon.DataSource") = dataView.Table
grdCommon.DataBind()
End If
end sub

hi,
Here i add a sample code for sorting
1) In Gridview Properties add this
AllowSorting="true" OnSorting="gridView1_OnSorting"
2) In gridView use TemplateField Column
<asp:TemplateField HeaderText="joiningdate" HeaderStyle-HorizontalAlign="Left" SortExpression="joiningdate" ItemStyle-Width="30%">
<ItemTemplate >
<span id="joiningdate" runat="server" style="color:Black;" ><%#Eval("joiningdate") %></span>
</ItemTemplate>
</asp:TemplateField>
3) create a Event gridView1_Onsorting
protected void gridView1_OnSorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
ViewState["sortExpression"] = e.SortExpression;
if (GridViewSortDirection == SortDirection.Ascending)
{
GridViewSortDirection = SortDirection.Descending;
SortGridView(sortExpression, "DESC");
}
else
{
GridViewSortDirection = SortDirection.Ascending;
SortGridView(sortExpression, "ASC");
}
}
4) Create a SortGridView() Method
private void SortGridView(string sortExpression, string direction)
{
DataTable dt = null;
dt = "test" // fill the Datatable rows using sqlcommand or Dataset
DataView dv = new DataView(dt);
dv.Sort = sortExpression + " " + direction;
gridView1.DataSource = dv;
gridView1.DataBind();
}
5) Create a enum SortDirection
public SortDirection GridViewSortDirection
{
get
{
if (ViewState["sortDirection"] == null)
ViewState["sortDirection"] = SortDirection.Ascending;
return (SortDirection)ViewState["sortDirection"];
}
set { ViewState["sortDirection"] = value; }
}

Hi,
How to save data from a html table to database.
eg: my html table, it is dynamically generated using string concadination
name age address city
N1 10 xyz abc
N2 20 abc xyz
I need to read this html table and save it to database
How to do this?
Thankyou
YPKI

Say you paste the html into a container div. Now you can get the inner HTML in the server side of the div. Now parse the table from it.
Otherwise if you like to create the entire htmlTable with view state and all, you need to create the object during pre_Init.

This is the chat box where every second gets refresh with AJAX. But,here the dataset (ds) is filled by other order detail, lead to get wrong messages in the chat box.
How to fill ds for every second from SQL database without conflict?
VB Code
lsSQL = "select MSG_Message from tbl_message where MSG_Orderno='" & orderno & "' order by MSG_ID"
Dim DtSqlAdp6 As New SqlClient.SqlDataAdapter(lsSQL, DbCon)
DtSqlAdp6.Fill(ds)
|
|

|

Good Day j_u_sankar
There is Probably a better way of doing this, but anyway. To Clear the dataset you must Add the Following code
DtSqlAdp6.Clear()
before you fill the dataset.

i'm using the same stored procedure in both the main and sub report.
if some one has come across this sort of issue plz let me know how to overcome, i will be happy to explain you the problem in detail if some one is interested.

}
as you can see the code, the values are comming from a webConfig, you can change them so that they come from your ASP.NET page.

Hi!
Can someone please tell me how I can retrieve the UserId from the aspnet_users table when I use the login tools in ASP.NET?
I am logging in as registered user and then when I click on edit profile I need the edit profile page to load with the UserId because I have made a one-to-one relationship between aspnet_users and Person table.
I am using a DataSet in a Seperate DAL. Basically I have configured the query to select record by UserId but I cannot get the correct GUID value from the aspnet_users table when going to editprofile page.
Thank you!!
Illegal Operation

u can get the UserId of any user via it's UserName. Firstly u can get the instance of MembershipUser then from this instance u will be able to get the Guid or UserId of that user. This same value is going to store in the aspnet_users table.
MembershipUser user = Membership.GetUser("UserName");
Guid userId = (Guid)user.ProviderUserKey;
You can get the UserName of the currently loggedin user via Context.User.Identity also.

Hi, everyone. The situation is, I am converting a tiff image file into byte[], then to stream then saving it as jpeg image format, then display it on browser, so that the jpeg opens in a picture viewer instead of webpage. The code works in IE 6 and firefox, but does not work in IE 7. In IE 7, the blank page appears and automatically closes. The code is as follows:-
System.IO.Stream _stream = new MemoryStream(byteArray);
Bitmap _bmp = new Bitmap(_stream);
Response.Clear();
Response.AddHeader("Content-Disposition","attachment;filename=adc.gif");
Response.ContentType = "image/gif";
_bmp.Save(Response.OutputStream, ImageFormat.Gif);
Response.End();
_bmp.Dispose();
_stream.Close();
This code is called in the page_load of a page in server a. Since the tiff image is located on a different server(server b) other than the web server, the image path is passed to web service located at server b, image is read and converted to byteArray and returned to server a. I guess the problem is with Content-Disposition.
Any help is appreciated.

Try this
============
byte[] message; // converting a tiff image file into byte[]
bool ret = false;
string filepath = "C:\";
if (Contentdisposition != null)
{
ret = Contentdisposition.StartsWith(" attachment;");
//code to decode the data
if (ret && (contentTransferEncoding.ToUpper().Equals("BASE64")))
{
//create the file and store the binart data
//store to test create the file with attachment name later
string[] filename = Contentdisposition.Split(';');
attachfile = filename[1];
attachfile = Regex.Replace(attachfile, "^[ | ]+filename=[\"]*([^\"]*).*$", "$1");
filepath+=attachfile;
m_binaryData = Convert.FromBase64String(message.Replace("\n", ""));
System.IO.BinaryWriter bw = new BinaryWriter(new FileStream(filepath, System.IO.FileMode.Create));
bw.Write(m_binaryData);
bw.Flush();
bw.Close();
}
}

I will begin by stating that I am NOT an ASP.NET developer. My new job now pushes me into it.
So with that said I'm trying to do the following:
This asp app is a single screen with the top 2/3 a bunch of dropdowns that the user selects to isolate a specific location.
Once that location is set, I need to dynamically add 4 - 6 legs which the user will provide the name for each leg.
I want to do this one leg at a time so I have a place holder named insertHere and a usercontrol with a lable, textbox, and button which says "Next Leg".
When I click the button Create Legs....my first leg control shows just fine. I enter a leg ID and click the Next Leg button (part of the control). My Next Leg process is this:
protected void NextEventHandler(object sender, EventArgs e)
{
if (NextEvent != null)
{
this.next.Visible = false;
NextEvent(sender, e);
}
}
The idea is to make the button invisible then fire the NextEvent up to the parent container. My NextEvent code is simple right now:
protected void HandleNextEvent(object sender, EventArgs e)
{
CreateLegsRequestHandler(sender, e);
}
What happens is this: when I click the button Next Leg, my entire control goes invisible and I do not see either the Leg One control or the Leg Two control being displayed. I'm puzzled and confused. Can the ASP.NET gods please help me with why it isn't working?
My desired result:
xxxxx dropdown
xxxxx dropdown
xxxxx dropdown
xxxxx dropdown [Create Legs]
(within PlaceHolder(insertHere).Controls)
Leg 1 textboxValue1 -invisible buttons-
Leg 2 textboxValue2 -invisible buttons-
Leg 3 textboxValue3 -invisible buttons-
Leg 4 _____________ [Next Leg] [Done]

Dynamic controls created like this will not have viewstate persisted. When you use dynamic controls, you need to recreate it on every postback.
Michael Eber wrote:
(within PlaceHolder(insertHere).Controls)
Leg 1 textboxValue1 -invisible buttons-
Leg 2 textboxValue2 -invisible buttons-
Leg 3 textboxValue3 -invisible buttons-
Leg 4 _____________ [Next Leg] [Done]
What you need here is to display tabular data. GridView will be the best control and it handles viewstate very well. To get your desired result, use a GridView with necessary columns. Use TemplateColumn to display text box and button. When Create Leg is clicked, add a new row to the GridView's data source and rebind the gridview.

Okay...I've been tinkering with this so far and have a few questions....
First: I have a dropdown box and I defined an OnSelectedIndexChange event. When I run the application and I select an item in the dropdown box, my next dropdown box is not populated!
UIPDATE: I believe I got this fixed. Set the dropdowns to AutoPageBack (or something like that).
Second: When I add dropdown lists to the GridView do I also use a TemplateColumn?
Finally: I must be using the TemplateColumn incorrectly. If it is in the Gridview it complains no such type exists.
If I add a <Column> header then add the TemplateColumn I get a different error. Where to I add the TemplateColumn?
Do I use a <Field> header instead?

On my page I have a plain Gridview Control.
<asp:GridView ID="GridView1" runat="server"></asp:GridView>
In the code behind, I populate a dataview and bind it to the Gridview.
Me.GridView1.DataSource = objSF.DV
Me.GridView1.DataBind()
This works fine.
Now I want to change the formatting of column(4) to be formatted as currency.
I've tried, CType(Me.GridView1.Columns(4), BoundField).DataFormatString = "{0:c", in various Gridview events with no success;
in fact, it appears that everywhere I try the above code, the Grid reports that there are no columns at all !
I've used, System.Diagnostics.Debug.WriteLine(Me.GridView1.Columns.Count.ToString) in the following events and gotten zero as a result.
GridView1_RowCreated
GridView1_DataBound
GridView1_PreRender
GridView1_RowDataBound
What am I doing wrong ?
How can I format a column to display the data as currency ?
Regards,
David

From ASP.NET 2.0 everything is encoded using HTMLEncode which prevents any modification being done to the bound controls. Just use like this :
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:BoundField DataField="CurrencyField" HeaderText="Amount" DataFormatString="{0:c}" HtmlEncode="false" />
</Columns>
</asp:GridView>
You can see I placed HtmlEncode=false.. This is required for every BoundField in Gridview to reformat the data.
I am hoping this would work...
