Get values from selected item in listview using asp.net c#
I've tried many many different ways of displaying values from listview to either textbox or just store it in session and use it later, but none of it works.
I was able to make it work for GridView, but i just can't make it work for ListView.
The idea is to get id of selected user (in gridview) and id of selected club (in listview)
After getting and storing both id's from selected rows, i can add club to another user.
Let's say i have table Clubs which has item: (4 columns, 1 row)
ID: 1 ClubName: Los Angeles Lakers City: Los Angeles State: California
When i press on the first row, it should highlight in a different color, and then store ID either to session or just textbox. Doesn't really matter as i'll decide that later. But can you guys please help me get ID ?
This is source code

This is code - my latest, doesnt work
protected void GridView1_RowCreated(object sender, System.Web.UI.WebControls.ListViewCommandEventArgs e)
{
ListViewDataItem item1 = e.Item as ListViewDataItem;
int findMe = item1.DisplayIndex;
var route = (Label)item1.FindControl("ID");
TextBox1.Text = route.Text;
}
Any input would be appreciated, thank you!
PS, IS IT POSSIBLE TO HAVE TWO GRIDVIEW WHICH WOULD STORE DIFFERENT DATA?
I tried this before, but everytime i selected item in 2nd gridview, the item from 1st gridview was getting selected.

no need to convert it to webControl just ::
ListViewItem item = ListView1.Items[ListView1.SelectedIndex];
Label c = (Label)item.FindControl("here type the lable id!!");
//then use
string result=c.text;// you get the value or the text of the Label ,,

this is the handler of GRidView Events not listView Events
GridView1_RowCreated()
Actually I have the same issue as you ,, and I found a way to get the id of selected raw ,,
int id =(int) ListView1.SelectedDataKey.Value;
// if the Id is
// the datakey which i think the primary key""
and if you want to get the data of different column in the selected listView raw::
ListViewItem item = ListView1.Items[ListView1.SelectedIndex];
WebControl c = (WebControl)item.FindControl("here type the lable id!!");
Label la = (Label)c;//to get the text of the label by using c.Text;
because i am a beginner i convert two times ,, Of course there will be a better way << but what to do if no expert answer
