Case 1 (working fine)
combobox1
combobox2
Case 2 (issue)
combobox1
for
example "H" combobox2
filter word
"B"combobox1
- just showing which values
starting "H"combobox2
- just showing which values starting "B" Code; aspx
<ext:ComboBox ID="combobox1 " runat="server" DisplayField="CountyName" ValueField="ISSCode" QueryMode="Local">
<Store> <ext:Store ID="str1" runat="server" AutoDataBind="true">
aspx.cs
Before databind I used clearfilter()
str1.ClearFilter();
str1.DataSource = countyDataTable;
str1.DataBind();
Try this solution
combobox1.Reset();
strCounties.DataSource = countyDataTable;
strCounties.DataBind();
