Thanks for contacting Syncfusion support.
Since we are not able to get your requirements clearly. We make simply the hierarchy between two generic dropdown to achieve linkage between two generic dropdown. To achieve this use the “OnTextChanged” serverside event for primary dropdown. And using this event bind the values for secondary dropdown. Please refer the following code snippet.
<syncfusion:GenericDropDown ClientObjectId="Generic" AutoPostBackOnTextChanged="true"
ID="GenericDropDown1" runat="server" Width="150px" OnTextChanged="GenericDropDown1_TextChanged">
protected void GenericDropDown1_TextChanged(object sender, Syncfusion.Web.UI.WebControls.Shared.GenericDropDownTextChangeEventArg e)
if (GenericDropDown1.Text == "Tools")
TreeViewNode node1 = new TreeViewNode();
node1.ID = "tools1";
node1.Text = "ASP";
TreeViewNode node3 = TreeView2.Items;
node3.Text = "Tools";
gdd.Text = "-Select-";
For your reference we have prepared the sample to exhibit this behavior, its available in below link.
If your requirement is different form hierarchy generic dropdown, kindly let us know with further more details.
Thanks & Regards
