[CLOSED] Problem selecting items in Combobox
Hi, i'm updating a combobox based on whats selected in a grid.
I'm updating the data successfuly, but then i cannot select the items of the combo. Any idea of why? How can i solve this?
Thanks!
Here's my code:
Code:
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
class SomeClass
{
public string ID { get; set; }
public string Test { get; set; }
}
void Page_Init(object sender, EventArgs e)
{
Configure();
}
void Page_Load(object sender, EventArgs e)
{
LoadData();
}
protected void Configure()
{
if (UserCanChangeData())
{
GridPanel1.SelectionModel.Add(new CheckboxSelectionModel());
}
else
{
GridPanel1.SelectionModel.Add(new RowSelectionModel() { SingleSelect = true });
}
((RowSelectionModel)GridPanel1.SelectionModel.First()).DirectEvents.RowSelect.Event += new ComponentDirectEvent.DirectEventHandler(RowSelect_Event);
((RowSelectionModel)GridPanel1.SelectionModel.First()).DirectEvents.RowDeselect.Event += new ComponentDirectEvent.DirectEventHandler(RowDeselect_Event);
Store store = this.GridPanel1.GetStore();
JsonReader reader = new JsonReader();
reader.IDProperty = "ID";
reader.Fields.Add(new RecordField("id") { Mapping = "ID" });
reader.Fields.Add(new RecordField("test") { Mapping = "Test" });
store.Reader.Add(reader);
JsonReader jr = new JsonReader();
jr.Fields.Add(new RecordField("id") { Mapping = "ID" });
jr.Fields.Add(new RecordField("test") { Mapping = "Test" });
comboGenerico.GetStore().Reader.Add(jr);
}
List<SomeClass> GetComboData()
