Hi,
I want to access a GridDropDownColumn ddl (DropDownList) not thourh an event as shown in your documentation (for example, onItemCreated event) but directly through the column:
How do I proceed from here?

Hi ,

Here is a repro for a bug, I dont think its the same as the one mentioned here: http://www.telerik.com/community/forums/aspnet-ajax/treeview/stack-overflow-on-nodeclick-after-serversidecallback.aspx



The FindNodeByValue method produces a Stack Overflow. I need a fix from Telerix as the Call Stack is inside the FindNodeByValue method and I cant see this without the pdb files, let alone change the source code...

        protected void Button1_Click(object sender, EventArgs e)
        {

            RadTreeView1.Nodes.Clear();
            RadTreeNode tn = new RadTreeNode();
            RadTreeNode childNode = null;

            Random rnd = new Random();
            for (int i = 1; i < 2000; i++)
            {
                tn = new RadTreeNode();
                tn.Text = i.ToString();
                tn.Value = i.ToString();
                RadTreeView1.Nodes.Add(tn);

            }


//for this repro, I put this loop below, however in my application it is nested in the above loop.
            for (int i = 1; i < 2000; i++)
            {

                childNode = RadTreeView1.FindNodeByValue(Convert.ToUInt32((rnd.NextDouble() -.001) * i).ToString());
                tn.Text = i.ToString();
                tn.Value = i.ToString();
                childNode.Nodes.Add(tn);   
            }






To avoid the StackOverflow I was hoping to bind the treeview to a datasource, eg:

OleDbConnection dbCon = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/Tree.mdb"));
                dbCon.Open();

OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM Links", dbCon);
DataSet ds = new DataSet();
adapter.Fill(ds);

RadTreeView1.DataFieldID = "NODEID";
RadTreeView1.DataFieldParentID = "PARENTID";
RadTreeView1.DataTextField = "TEXT";


However this project requires a TreeView with roughly 3600 nodes and some branches are 6 levels deep.. I cant bind since the Child and Parent IDs are NON-Unique:

1818    1819
1818    1886
1819    1820
1819    1847
1819    1875
1820    1846
1820    1821
1820    1833
1821    1831
1821    1826
1821    1827



Looking forward to your response, thanks

 I have a column in my group footer where I need to calculate a percentage. The percentage depends on which group I'm currently in. I've got code in ItemDataBound which checks to see if e.Item is a GridGroupFooterItem and if so, it does the calculation. However, I'm having a hard time trying to figure out which group I'm actually in. GridGroupFooterItem.GroupIndex is supposed to have it as a string, but it seems to start at "0", then go to "2", then "4", etc. This grid only has one level of grouping. I guess I could just calculate it based off of the GroupIndex or maintain my own group count but that seems weird - is there a more direct approach?

Hi,

I've almost got this Treeview Loaded On Demand working!!

My last question is how do you check a node that you load on-demand. I've tried CheckState, Checked, Checkable but no luck.

I cant find a sample that demonstrates how to check a node loaded on demand


My aspx:

  <telerik:RadTreeView runat="server" ID="RadTreeView1"
             OnNodeDataBound="RadTreeView1_NodeDataBound" CheckBoxes="true" CheckChildNodes="true"  
            LoadingStatusPosition="None" PersistLoadOnDemandNodes="false" EnableViewState="false"
            Style="float: left" OnClientNodeClicked="onNodeClicked" Width="300px">
            <WebServiceSettings Method="GetTreeViewNodes" Path="~/PopulateTreeview.asmx" />
            <Nodes>
             
            <telerik:RadTreeNode Text="mgpage_BalanceSheet" Checked="true" Value="1" ExpandMode="WebService"> </telerik:RadTreeNode>
            .....


My Code behind:

[WebMethod(EnableSession = true)]
        public List<NodeData> GetTreeViewNodes(RadTreeNodeData node)
        {
            DataTable dt = Helper.ConfigurationHelper.GetCofiguration(node.Text);
            List<NodeData> nodes = new List<NodeData>();
            NodeData nodeData = new NodeData();
            foreach (DataRow dr in dt.Rows)




 foreach (DataRow dr in dt.Rows)
            {
                nodeData = new NodeData();
                nodeData.Text =  dr["DisclosureCode"].ToString();
                nodeData.Value = dr["DisclosureCodeId"].ToString();
                nodeData.ExpandMode = TreeNodeExpandMode.WebService;
                nodeData.CheckState  = TreeNodeCheckState.Checked;
                nodeData.Checkable = true;
                nodeData.Checked = true;
                nodes.Add(nodeData);


        public class NodeData
        {
            public string Value { get; set; }
            public string Text { get; set; }
            public TreeNodeCheckState CheckState { get; set; }
            public bool Checked { get; set; }
            public bool Checkable { get; set; }
            
            public TreeNodeExpandMode ExpandMode { get; set; }
        }



thanks in advance


<edit>
This post http://www.telerik.com/community/forums/aspnet-ajax/treeview/on-demand-loaded-non-checkable-nodes.aspx#673490
recommends the latest Telerik DLL 2008.3.1105.35 and that resolves the problem.. no wonder it was doing my head in.

I see the FindNodeByText and FindNodeByValue, have second boolean parameter ignoreCase.. unfortunalely with the latest DLL I can still produce the StackOverFlow

I wanted to have 2 different popup form templates when editing the radgrid contents. The reason is that on "Update" mode, I don't want users to edit some fields (editable on "new record" mode). Is there a way to do this?

  in grid another column is Filtered when i click on the Filtered text box and press enter key then it show me that confirm box that i have putted on the other column.
how can i do this when user click in the filtered text box then it should filter the grid if filtered text box is not empty.

my grid is filling in needDataSource event and i am using the default filtering not any server side filtering.


Thanks.

hi

I have this code which was previouly in a Radgrid and the code works fine in the grid.

telerik:GridTemplateColumn HeaderText="Register" UniqueName="TemplateColumn">
            <ItemTemplate>
            <a href="#" onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"CATID")%>'); return false;">Register</a>
            </ItemTemplate>
        </telerik:GridTemplateColumn>

But when i changed this code to

<

td class="style102">

 

 

<a href="#" onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"CATID")%>'); return false;">Register</a></td>

 

which is now outside of a gird and became a hyperlink on its own in the page it gave me an error:
Compiler Error Message: BC30456: 'DataItem' is not a member of 'System.Web.UI.Control'

How do i pass parameter value using hyperlink since this hyperlink is no loner in a radgrid? Thanks

I have RadGrid on my page and doing batch updates for multiple rows of the grid. I want to highlight all the edited rows once updating operation completes successfully. How to highlight all the edited rows?
