NodeSelectionChanged not firing. Node is not selected.
posted

 Hey guys, I have an UltraWebTree that is not working as expected. It has 4 levels deep, and after the roor it starts with 2 leaves. One of them is never selected. After the user clicks on it, it will highlight for less than a sec, refresh the page and then highlight the previous leave, without firing the NodeSelectionChanged  event.

I just don't have a clue, could somebody help me please?

 HTML markup:

 <ignav:UltraWebTree id="UltraWebTree1" runat="server"
    DisabledClass=""
    NodeEditClass=""
    TargetFrame=""
    TargetUrl="" 
    OnNodeSelectionChanged="UltraWebTree1_NodeSelectionChanged"
    
    >             
    <Levels>
        <ignav:Level Index="0" LevelCheckBoxes="False"></ignav:Level>
        <ignav:Level Index="1"></ignav:Level>
        <ignav:Level Index="2"></ignav:Level>       
        <ignav:Level Index="3"></ignav:Level>       
    </Levels>         
  </ignav:UltraWebTree>

 

 

This is how I populate the WebTree 

 

 protected void Page_Load(object sender, EventArgs e)
    {
      if (!IsPostBack)
      {
        PopulateTreeView();
      }
    }

 
    public void PopulateTreeView()
    {
      DataTable facClassTable = FacClassBLL.getList();
      DataTable catGroupTable = CatGroupBLL.getList();
      DataTable basicCatTable = BasicCatBLL.getList();
      DataTable facAnalysisCat = FacAnalysisCatBLL.getList();
      DataSet dataSet = new DataSet("CatCodes");
      
      facClassTable.TableName = CacheKeys.FacClassList.ToString();
      catGroupTable.TableName = CacheKeys.CatGroupList.ToString();
      basicCatTable.TableName = CacheKeys.BasicCatList.ToString();
      facAnalysisCat.TableName = CacheKeys.FacAnalysisCatList.ToString();

      dataSet.Tables.Add(facClassTable);
      dataSet.Tables.Add(catGroupTable);
      dataSet.Tables.Add(basicCatTable);
      dataSet.Tables.Add(facAnalysisCat);

      dataSet.Relations.Add("FacClass_CatGroup",
          dataSet.Tables[CacheKeys.FacClassList.ToString()].Columns["FacClassSeq"],
          dataSet.Tables[CacheKeys.CatGroupList.ToString()].Columns["FacClassSeq"]);

      dataSet.Relations.Add("CatGroup_BasicCat",
          dataSet.Tables[CacheKeys.CatGroupList.ToString()].Columns["CatGroupSeq"],
          dataSet.Tables[CacheKeys.BasicCatList.ToString()].Columns["CatGroupSeq"]);

      dataSet.Relations.Add("BasicCat_FacAnalysisCat",
          dataSet.Tables[CacheKeys.BasicCatList.ToString()].Columns["BasicCatSeq"],
          dataSet.Tables[CacheKeys.FacAnalysisCatList.ToString()].Columns["BasicCatSeq"]);

      UltraWebTree1.DataSource = dataSet;

      UltraWebTree1.Levels[0].LevelKeyField = "FacClassSeq";
      UltraWebTree1.Levels[1].LevelKeyField = "CatGroupSeq";
      UltraWebTree1.Levels[2].LevelKeyField = "BasicCatSeq";
      UltraWebTree1.Levels[3].LevelKeyField = "FacAnalysisCatSeq";

      UltraWebTree1.Levels[0].RelationName = "FacClass_CatGroup";
      UltraWebTree1.Levels[1].RelationName = "CatGroup_BasicCat";
      UltraWebTree1.Levels[2].RelationName = "BasicCat_FacAnalysisCat";

      UltraWebTree1.Levels[0].ColumnName = "FacClassTitle";
      UltraWebTree1.Levels[1].ColumnName = "CatGroupTitle";
      UltraWebTree1.Levels[2].ColumnName = "BasicCatTitle";
      UltraWebTree1.Levels[3].ColumnName = "FacAnalysisCatTitle";

      UltraWebTree1.DataMember = CacheKeys.FacClassList.ToString();

      UltraWebTree1.DataBind();
    }



Any help would be greatly appreciated, thanks in advance !!!!

    Ulises,

    I'm not really sure I understand what the problem is, but it sounds like when you click on one of the nodes, it's not getting selected properly.  The first thing that comes to mind for me is, how are you assigning keys to the nodes?  Is it possible that two nodes have the same key?  Also are you augmenting the node structure in any way during the selection change event? 

    It's probably best if you work through this with our developer support department.  Go to http://ko.infragistics.com/gethelp for support options, note that email support is always free.
