TreeView

[LLM]

I built a treeview from a datatable on a windows form, but I am not understanding fully. I could not find anywhere to tell it what the id was going to be. My now I am showing has an associated ID. How do I assign this ID no the child nodes and then how do I pull out the id of the child node they clicked on?

Any help would be much appreciated.

hi lisa
this is prabu here.
i read ur query. but not clear to me.
plz be clear. i also did the same i think.
so i can clear u/

 
            // fill the tree node
            foreach (DataRow row in dtData.Rows)
            {
                node = tvOffender.Nodes.Add(row["OffenderName"].ToString());
 
                //get subs
                daData2 = new OleDbDataAdapter("SELECT LastName + ', ' + FirstName + ' ' + MiddleName + '  (' + convert(varchar(10), InsertDateTime, 101) + ')' AS Name FROM Registration " +
                                "WHERE ID = " + row["ID"].ToString() + "ORDER BY LastName, FirstName, MiddleName", strConnectionString);
                daData2.Fill(dtData2);
                foreach (DataRow row2 in dtData2.Rows)
                {
                    child = node.Nodes.Add(row2["OffenderName"].ToString());
                }
            }
 

I fill it like this. How do I assign the ID to my treeview and then grab it out when they click on it in the treeview to move to an edit page?

foreach (DataRow row in dtData.Rows)
{
node = tvOffender.Nodes.Add(row["Name"].ToString());


foreach (DataRow row2 in dtData2.Rows)
{
child = node.Nodes.Add(row2["RegistrationID"].ToString(), row2["Name"].ToString());
}
}



Can someone help? How do I get the ID of the selected node? tv.SelectedNode.value does not exist.. I am getting desperate!

hi lisa,
here u given registrationID as TreeNode text property and Name as Value property. i think regID is int!

code like this da,

child = node.Nodes.Add((string)row2["Name"], convert.ToInt32(row2["RegistrationID"]));

then
get the regID while u selecting the node,

RegID=Convert.ToInt32(tv.SelectedNode.Value);


plz be free and try don't get tension

foreach (DataRow row in dtData.Rows)
{
node = tvOffender.Nodes.Add(row["Name"].ToString());


foreach (DataRow row2 in dtData2.Rows)
{
child = node.Nodes.Add(row2["RegistrationID"].ToString(), row2["Name"].ToString());
}
}
