I hope it helps. Regards,
Check below my blog post
Ways to pass data between webforms
HC
Heres an example of what I'm doing:
Response.Redirect(passingpage.aspx&value={0}&value2=" & txtvalue2.Text)
The first value is from a hyperlink column of a datagrid which works fine by itself. When I try to pass the second value from a textbox, it doesn't work. I'm using visual basic.
Can anyone help?the first parameter is denoted by a ? and the subsequent ones a &
eg
http:www.costall.com/default.aspx?param1=hello&Param2=world
does this answer the question or is it a typo in the post?
I have tried that and it doesn't work. Any other suggestions?
can you post the code sample?
Hello, try this:
Dim url As String = "passingpage.aspx?value1=" & txtValue1.Text & "&value2=" & txtValue2.Text
Response.Redirect(url)
regards
I want pass value to 2nd DropDownList from 1st one. I use "DropDownList1.SelectedValue", but got error message." can't transfer data type from varchar,..." Yes, in Database, it is varchar type.
Here is a source code:
private void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
string sql = "select Address from myTable where Name=" + DropDownList1.SelectedValue ;
SqlConnection con = new SqlConnection(connectionString);
SqlDataAdapter da = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();
da.Fill(ds, "myTable");
DataView dv=ds.Tables [0].DefaultView ;
DropDownList2.DataTextField="Address";
DropDownList2.DataValueField ="Address";
//DropDownList2.DataSource =ds.Tables[0].DefaultView;
DropDownList2.DataSource=dv;
DropDownList2.DataBind ();
con.Close();
}
Two things.
1) I would use a SqlDataReader to populate the DropDownList. It is 100x faster than a DataSet.
2) Try DropDownList1.SelectedItem.Value to get the value of the DropDownList
move your datasource code line above both your datatextfield and datavaluefield
[edit]
He is right about the speed--much faster.
You are missing the single quotes around the parameter, try:
string sql = "select Address from myTable where Name='" + DropDownList1.SelectedValue + "'" ;

how are you getting to the second page? Just write the QueryString onto
the link, or in the redirect.

Hi AB,
I think this book is good cause the other is recognized as a good teacher.
I haven't read it though (I came from classic asp and read on the internet
the howto's)
http://www.amazon.com/exec/obidos/t...=books&n=507846
Jesse Liberty also knows how to write a book :

The simplest way to solve your problem is to do a response.redirect to the
file you wish to push to your user.
Let me know if you have any more questions...
Cheers,

I have 2 asp.net forms. In the first form I create a one dimensional array and copy that array into a session object. In the second form I want to read the elements of that array. Everything I've tried results in either a casting error, a late binding error or nothing at all. The following code shows what Iwant to do.
Form one: Dim aArray(2) as stringaArray(0) = "zero"aArray(1) = "one"Session("PassArray") = aArrayForm two: Dim aTest(2) as stringaTest(0) = CType(Session("PassArray(0)"), String)aTest(1) = CType(Session("PassArray(1)"), String)When I run form two in the editor, I can Watch Session("PassArray") and see:Session("PassArray") {System.Array} object-- (0) "zero" string-- (1) "one" stringSo I know it's there and available, but how do I read the extents.Could really use a simple code example to explain what I'm doing wrong.
Hi,
Use this on the second form:
Dim aTest() As String = CType(Session("PassArray"), String())
