RadDropDowmTree

[Vishram]

Hi, I am writing the statement like,
 int value=Convert.ToInt32(objRadDropDowmTree.EmbadedTree.Nodes[1].Value);

But its showing an error "Input string was not correct"
 Please tell me, how to access any specific node value? 

Please also help me, how to assign tooltip in RadDropDowmTree Nodes .

Hi Vishram,

Please have a look into the C# code snippet to access the value of the node and assign tooltip for the node.

C#:

protected void RadDropDownTree1_NodeDataBound(object sender, DropDownTreeNodeDataBoundEventArguments e)
{
    string value = string.Empty;
    foreach (RadTreeNode node in RadDropDownTree1.EmbeddedTree.Nodes)
    {
        node.ToolTip = node.Text;
        value = node.Value;
        foreach (RadTreeNode subnode in node.GetAllNodes())
        {
            subnode.ToolTip = subnode.Text;
        }
    }
}

Thanks,
Shinu.

Hi Shinu,
 Actually I am accessing node value using index, and assigning that value in a integer variable but showing "input string was not correct"...

Please see this statement....  

 int value= Convert.ToInt32(objRadDropDowmTree.EmbadedTree.Nodes[1].Value);

Hi Vishram,

The error means that the string you are trying to parse an integer doesn't actually contain a valid integer. Can you please check the DataValueField have integer values. Please have a look into the sample code snippet which works fine at my end.

ASPX:

<telerik:RadDropDownTree ID="RadDropDownTree1" runat="server" DataSourceID="SqlDataSource1"
    DataTextField="text" DataFieldID="id" DataFieldParentID="parentid" DataValueField="id">
</telerik:RadDropDownTree>
<telerik:RadButton ID="RadButton1" runat="server" Text="Value" OnClick="RadButton1_Click">
</telerik:RadButton>

C#:

protected void RadButton1_Click(object sender, EventArgs e)
{
    int value = Convert.ToInt32(RadDropDownTree1.EmbeddedTree.Nodes[1].Value);
}

Please provide your full code if it doesn't help.
Thanks,
Shinu.

Hi Asutosh,

Please try the below JavaScript to achieve your scenario.

JavaScript:

function pageLoad() {
    var treeView = $find("<%=rtreeviewEmployees.ClientID%>");
    var count = treeView.get_allNodes().length, index, node;
    for (index = 0; index < count; index++) {
        node = treeView.get_allNodes()[index];
        if (node._hasChildren() == false) {
            if (node.get_text().length > 4) {
                node._element.title = node.get_text();
                node.set_text(node.get_text().substring(0, 4) + "...");
            }
        }
    }
}

Thanks,
Shinu.

Hi Asutosh,

Please try the below CSS code snippet to achieve your scenario.

CSS:

div.RadTreeView .rtIn

    text-overflow: ellipsis;
    display: inline-block;
}
div.RadTreeView .rtUL .rtIn
{
    width: 80px;
}
div.RadTreeView .rtUL .rtUL .rtIn
{
    width: 50px;
}

Thanks,
