I have a serious problem with updatepanel and checkedchanged event. When the checkbox is in the updatepanel the checkedchanged event never fires when i step through my code, even though auto postback is enabled.
Is there a little trick to this that I'm missing?

try adding the checkedbox to the trigger collection of the UpdatePanel
|
|
|
|
|
Above step + Make the UpddateMode to Conditional.

Thanks alot, that worked fine... Its odd I forgot completely that i had set it to conditional about two weeks ago, and that was causing the problem.

In my app there are a lot of CheckBoxes in UpdatePanels all fireing the CheckedChanged event.
Could you please post a bit of your aspx definition, otherwise it is impossible to help.
btw: I do not use the trigger collection on the UpdatePanel, UpdatePanels are all set to Conditional as UpdateMode.

Which database?
Which language?
Use an OleDbConnection and a command object to perform a sql query and then as you loop through your results populate the list. You can find documentation on this in the MSDN.

try the following code:
C#:
-----
SqlConnection con = new SqlConnection(connectionString);
String sql = "SELECT <field name=""> FROM ";
SqlCommand cmd =new SqlCommand(sql,con);
SqlDataAdapter sda =new SqlDataAdapter(cmd);
DataTable dt =new DataTable();
con.Open();
sda.Fill(dt);
DropDownList1.DataSource =dt;
DropDownList1.DataBind();
|
|
|
|
|
SqlConnection con= new SqlConnection("Server=IBM;DataSource=Master;User Id=sa;Pwd=sa");
SqlDataAdapter ada=new SqlDataAdapter("select * from customer",con);
DataSet ds=new DataSet();
ada.Fill(ds);
DropDownList1.DataSource=ds1.Tables[0];
DropDownList1.DataTextField=ds1.Tables[0].Columns[1].ToString();
DropDownList1.DataValueField=ds1.Tables[0].Columns[1].ToString();
DropDownList1.DataBind();

First create Connection with database and then
Dim databaseRecord As SqlDataAdapter
Dim dstRecord As DataSet
databaseRecord = New SqlDataAdapter("Select * from ", con)
dstRecords = New DataSet
databaseRecord .Fill(dstRecords)
dropdownlistname.DataSource = dstRecords
dropdownlistname.DataTextField = "<table_column_name>"
dropdownlistname.DataValueField = "<table_column_name>"
dropdownlistname.DataBind()

The Calendar Control has a property called SelectedDate. When you post back your first page, store that value from Calendar1 into a session variable. On your second page, you set Calendar2's SelectedDate to the session variable that has the original date.

You should know. After all, you are THE KNOWLEDGE, no? 
Search online for CSS stylesheets, you will find plenty of examples

Hi to all.
I have problem here. I need to get array of directories contained in the directory where my default.aspx is. If I write so:
<br />
DirectoryInfo dir1 = new DirectoryInfo(@".");<br />
I'm getting the "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE" directory.
My question is: how can I get the DirectoryInfo of the directory where my default.aspx file is, not pointing to DirectoryInfo constructor the whole path?
|
|
|
|
|
string[] dirs = Directory.GetDirectories(Server.Mappath(""));
Please let me know if it helps.
|
|
|
|
|
Should I include some additional namespace?
|
|
|
|
|
Thank you a lot. It really helped.
