Generic Dropdown

[Nitin]

Hi,

I am looking to add items in generic dropdown and change the selected value on runtime, but I didn't see any suitable property for the same.

Please let me guide how I can achieve it.

Thanks
Nitin

Hi Nitin,

Thanks for your interest in syncfusion products.

If your intention is to highlight the selected item in the items added to the GenericDropDownControl then it can be achieved by enabling the selected property of the corresponding item. Here we have created a simple sample for adding TreeView in GenericDropDown control and by default the items with value 7 will be selected then during run time the item will be highlighted based on the items selected. Please find the below code snippet to achieve this,

[VB]
Protected Sub tree_NodeSelected(ByVal sender As Object, ByVal e As Syncfusion.Web.UI.WebControls.Tools.TreeViewNodeSelectEventArgs)
 GenericDropDown1.Text = TreeView1.SelectedNode.Text //displays the selected item text in GenericDropDown1
End Sub

    Protected Sub TreeView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles TreeView1.DataBound
        findValue(TreeView1.Items)      
    End Sub
    Protected Sub findValue(ByVal items As TreeViewItemCollection)
        For Each item As TreeViewNode In items
            If (item.Value.Equals("7")) Then
                item.Selected = True //highlight the item which has the value “7”
                GenericDropDown1.Text = item.Text
            End If
            If (item.HasSubNodes) Then
                findValue(item.Items)//this continues recursively to highlight the items
            End If
        Next

    End Sub

Kindly download the sample from the following link,

Please try the sample and let us know if this helps.

Hi Chetan,

Thanks for the Update.

To send the selected value from the drop down to the controller use the following code to achieve it.

[Javascript]
  $.ajax({
                type: 'Post',
                data: { input: selText },
                dataType: "json",
                success: function (result) {

                    obj.setText(result.input);
                }

            });

Also I have created a simple sample and attached in the below link for your reference,
