Adding Alert message for specific nodes at runtime

[Sudhanva]

Hi,

I want to add an alert message to some nodes in my RadTreeView.
Following is my code.

int temp = 0;
        foreach (RadTreeNode node in rdtreeTeamBrand.Nodes)
        {
            if (node.Nodes.Count > 0)
            {
                for (int i = 0; i < node.Nodes.Count; i++)
                {
                    RadTreeNode brandNode = node.Nodes[i];
                    foreach (DataRow row in tblTeamBrandDetails.Rows)
                    {
                        if (node.Value == row["TeamID"].ToString() && brandNode.Value == row["BrandID"].ToString())
                        {
                            node.Checked = true;
                            brandNode.Checked = true;
                            temp = Convert.ToInt32(objconfig.CheckBrandSwotForPlanPeriod(Convert.ToInt32(node.Value), Convert.ToInt32(brandNode.Value), PlanningPeriodID));
                            if (temp != 0)
                            {   //this is where im adding the radalert at..
                                brandNode.Attributes.Add("onclick",
                                    string.Format(@"
                                function _showAlert() {{Sys.Application.remove_load(_showAlert);
                                radalert('{0}', null, 100, '{1}');}};
                                Sys.Application.add_load(_showAlert);", "Brand will be excluded from the PlanningPeriod.", "Novartis iPlan"));

                                brandNode.ForeColor = System.Drawing.Color.Navy;
                            }
                        }
                    }
                }
            }
        }

This is how a part of the Treeview looks in html

<div class="rtTop">
                                        <span class="rtSp"></span><input type="checkbox" class="rtChk" /><span class="rtIn">AFIN</span>
                                    </div></li><li class="rtLI"><div class="rtMid">
                                        <span class="rtSp"></span><input type="checkbox" class="rtChk" /><span class="rtIn">FEM</span>
                                    </div></li><li class="rtLI"><div class="rtMid">
                                        <span class="rtSp"></span><input type="checkbox" class="rtChk" checked="checked" /><span class="rtIn" onclick="
                                function _showAlert() {Sys.Application.remove_load(_showAlert);
                                radalert('Brand will be excluded from the PlanningPeriod.', null, 100, 'Novartis iPlan');};
                                Sys.Application.add_load(_showAlert);" style="color:Navy;">PROLE</span>
                                    </div>

This is not working. I am getting a alert with null as text, onclick of these nodes.

Please help.
