Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,
Kirupa

Thread: change the data source during runtime in C#

  1. #1

    change the data source during runtime in C#

    I have a tree view which works fine but I want to change the data source during runtime in C#
    The data is stored procedures and I want the user to be able to type criteria then re-bind the treeview
    I cannot see a way in to this
    any ideas please

  2. #2
    I use dataset and coding like this:
    private void FillTreeNodes()
    {
    this.tvCatalogue.Nodes.Clear();

    string sgId;
    CatalogueMainGroup curmain;
    for (int i = 0; i < myTables.MainGroup.Length; i++)
    {
    curmain = myTables.MainGroup[i];
    if (curmain != null)
    {
    sgId = i.ToString() + ": " + curmain.Title;
    this.tvCatalogue.Nodes.Add(sgId);
    FillSubNode(this.tvCatalogue.Nodes.Count - 1, curmain.Id);
    }
    }

    }

    private void FillSubNode(int parentNode, int mainId)
    {
    string sgId;
    CatalogueSubGroup cursub;
    for (int i = 0; i < myTables.SubGroup.Length; i++)
    {
    cursub = myTables.SubGroup[i];
    if (cursub != null)
    {
    if (cursub.MainGroupId == mainId)
    {
    sgId = i.ToString() + ": " + cursub.Title;
    this.tvCatalogue.Nodes[parentNode].Nodes.Add(sgId);
    }
    }
    }
    }

  3. #3
    ps: Sory, that example use a String array to fill node. The point is how to fill the node:
    this.tvCatalogue.Nodes.Add(sgId);
    this.tvCatalogue.Nodes[parentNode].Nodes.Add(sgId);
