When you change the selection of combo box, the page gets a post back and your combo box is again assigned the old value it had earlier.
You need to decide, weather you want to use the AutoPostBack property of the combobox or check the IsPostPack property of the page while assigning the value to combobox.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

One column on my gridview is an asp commandfield. When a user clicks on a row in this column how can I execute a client side java script function instead of the code behind function?
|
|
|
|
|
Convert your commandfield column as templatefield then replace the item template control by regular html link tag.

check the credentials and mail server.
you use smtp service?
some like this:
public static void sendMail(string _to, string _subject, string _body)
{
MailMessage correo = new MailMessage();
correo.From = new MailAddress(_emailFrom);
correo.To.Add(_to);
correo.Subject = _subject;
correo.Body = _body;
correo.IsBodyHtml = false;
correo.Priority = MailPriority.Normal;
SmtpClient smtp = new SmtpClient();
smtp.Host = _server;
smtp.Credentials = new NetworkCredential(_user, _pwd);
try
{
smtp.Send(correo);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "TestOfApplication",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
CheckBox chk = new CheckBox();<br />
chk.Attributes.Add("name", e.Row.Cells[100].Text);
e.Row.Cells[0].Controls.Add(chk);<br />
<br />
}<br />
<br />
protected void Button1_Click(object sender, EventArgs e)<br />

Int16 count = (Int16)GridView1.Rows.Count;<br />
for (Int16 i = 1; i < count; i++)<br />
{<br />
CheckBox chk = (CheckBox)GridView1.Rows[i].Cells[0].Controls[1];<br />
string id = CheckBox3.Attributes["name"];<br />
}<br />
}<br />

I have a class that inherits from CompositeControl that dynamically creates controls at runtime (typically 2-5 DropDownList controls). All of the control creation is happening in CreateChildControls().
When a page using that control first loads everything is correct. However, after the selected index is not being remembered. It doesn't matter what is selected in the DropDownList controls, SeletedItem or SelectedValue is always the first item in the control.
I then found some posting that said AutoPostBack needs to be set on the DropDownList Controls and that a check for IsPostBack needed to be put in CreateChildControls(). I did that but when a new item in any of the DropDownList controls was selected, all of the DropDownList controls were empty.
I then saw something that said for the ViewState to be preserved, the DropDownList control must first be added (i.e. Controls.Add()) and then load the control. That didn't help either.
Has anyone done anything like this before? Any guidance and how to get this thing to work?
Thanks!

i have dropdownlist1,dropdownlist2,textbox1,button1,button2,dropdownlist3
here i am selecting an item from each dropdownlist, perform concatinating and i showed in textbox fine.
but when i want to enlarge concatination means the selected item text will be overridden on the previous selecteditem text
i want to prevent this..
finally i want the TextBox2 output as follows;
exa:
(ddl1) (ddl2) (txt1) (btn1) (ddl) (ddl2) (txt1) (ddl3)
Month_no = 5 and Quarter_no = 3 group by(abc)
means
month_no = 5 and quater_no = 3 group by(abc)
how to get this one.........
help me out...

Koti

use the string format
Month_no = string.Format("{0} {1} {2} {3} {4} {5} {6} ({7})", (ddl1),(ddl2),(txt1) (btn1),(ddl),(ddl2),(txt1),(ddl3));
happy coding...

Hi
I have a trouble displaying Web Crystal Report from NT Current Event Log .
Using Crystal Reports 2008 I have created RPT file, with a data source NT Current Event Log, showing Security log from a network server from my LAN. The report is running fine from the designer, and also it runs fine from Visual Studio 2008 (C#) IDE
But if I try to deploy and run it from the web server, it fails.
I think that the user IUSR_MYServer that is running the web apps doesn't have right to open the remote EventLog, that's why I would like to supply another user/password on the connection
Is there any way to supply user name/password to the Crystal Reports web report, reporting from a remote server EventLog (Crystal Reports 2008)
Can I specify something similar to ADO connectionString (from code, dynamically), so I can specify the user/password
In my case I use VS 2008 (aspx 3.5, C#), CrystalReports 2008
Has somebody experienced this problem and what can be the solution?
regards,
Yakimo

Private Function Uploaded() As String
Dim filePath As String = AppSettings("~\Images")
Dim SaveLocation As String = String.Empty
If Not txtImgURL.Text.Length = 0 And Left(txtImgURL.Text, filePath.Length) <> filePath Then
Dim fileName As String = System.IO.Path.GetFileNameWithoutExtension(txtImgURL.Text).ToLower()
Dim fileExtention As String = System.IO.Path.GetExtension(txtImgURL.Text).ToLower()
SaveLocation = System.IO.Path.Combine(filePath, fileName & fileExtention)
Dim physicalLocation As String = Server.MapPath(SaveLocation)
If File.Exists(physicalLocation) = True Then
Dim sequencer As Integer = 1
SaveLocation = System.IO.Path.Combine(filePath, fileName & "_" & sequencer.ToString & fileExtention)
physicalLocation = Server.MapPath(SaveLocation)
Try
My.Computer.FileSystem.CopyFile(txtImgURL.Text, physicalLocation)
Catch
My.Computer.FileSystem.CopyFile(Server.MapPath(txtImgURL.Text), physicalLocation)
End Try
Else
Try
My.Computer.FileSystem.CopyFile(txtImgURL.Text, physicalLocation)
Catch
My.Computer.FileSystem.CopyFile(Server.MapPath(txtImgURL.Text), physicalLocation)
End Try
End If
End If

In Word you can only store 2 bytes. That is why I use Writer.
