im passing gridview row value to next page using linkbutton with session.But i got this error "Unable to cast object of type 'System.Web. UI.WebControls. GridView' to type 'System.Web.UI.WebControls.LinkButton'." and my code is
PAGE 1
Protected Sub gridview1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gridview1.RowCommand
Dim RefNo As String Dim LnkRefNo As LinkButton
LnkRefNo = e.CommandSource
RefNo = Convert.ToString(LnkRefNo.ToolTip.ToString())
Session("ref") = RefNo.ToString()
Response.Redirect("update.aspx")end sub

textbox1.Text = Convert.ToString(Session("ref"))

i have a gridview with link button and one field called "ID"
if i click that link button that "Id" values should pass to next page using "SESSION" variable in vb.net
In my app, I am displaying an Rss Feed, I have a button that takes the user to another form where they can select a them. Upon selecting the theme, they are taken back to the original form.
If the user has selected which theme they want to view then they click on the button to change theme, I need to pass the information about what rss feed they were viewing through session so that once they select the theme they want they are redirected back to the main page and the rss feed they were viewing should still be displayed.
Since I've already bound the data to the xmlDataSource and DataList I am trying the following:
Session.Add("CurrentRssFeed", XmlDataSource1.DataFile);
Session.Add("CurrentDataList", DataList1);
I'm not sure I am passing the data over correctly and I'm not sure how to specify it in the page_preinit.
i have a gridview with link button and one field called "ID" i have five values....when i click the link button that row value ill show in next page in textboxes ,txtid, txtage, txtsalary,......... if i click that link button that "Id" values should pass to next page using "SESSION" variable in C#.net
View 1 RepliesAssume the following html form is on [URL]in which you enter first name and last name and click the button.
<body>
<form id="form1" action="Result1.aspx" method="post" >
<p>
First Name:
<input id="FName" type="text" name="FName" /></p>
<p>
Last Name:
<input id="LName" type="text" name="LName" />
<input id="Submit1" type="submit" name="submit" value="submit" /></p>
</form>
</body>
The form1 posts data and you will see the Result on [URL] which simply shows your data.
<body>
<form id="form1" runat="server">
<div>
Result is:<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
Here is a sample code for the result page: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim SB As New StringBuilder()
Dim NVC As NameValueCollection = Request.Form
Dim nextKey As String
For counter As Integer = 0 To NVC.AllKeys.Length - 1
nextKey = NVC.AllKeys(counter)
[Code.....]

Below is my rough first attempt for a generalized method for textboxes:
Load Session:
[code]....
However, it appears that the Controls collection is not working for me. What am I doing wrong?
this.Controls.OfType<TextBox>() yields no results at run time when I do a quick watch on it.
I searched on this all morning, but I'm still not sure. If I create a session variable to pass some data between a couple of pages, does that variable time out after it reaches the timeout period set on IIS, or will it persist for the entire time the user keeps a session alive? For example, session variable is used shortly after login and then never again. Susy uses other pages for two hours and keeps session active. Did that first session variable die after 20 minutes, or is it still there 2 hours later?

View 4 RepliesI am using Visual Studio 2008.
I created a New Project ASP.NET Web Application.
I created a Textbox named VisitorName. The visitor puts in their name and it goes in VisitorName.Text
There is a Label that says "Which do you own?"
There is a RadioButtonList. It has Cat, Dog and None.
There is a button that says Add to list.
The button needs to add the results of the above items and put them in the list.
Now you keep adding people and their pets.
Once there are all entered you press send and I get the results for everyone entered during that session via email.
I have no database access and the information does not need to be stored in such a way.
I would like to use a datatable or datalist or something to that sort.
Oh and I would like the visitor to be able to click on a name in the table and edit the data using the form controls not in the datalist or datatable itself.
