This topic shows how to set search indexes at runtime depending on a selected value.
After creating several indexes for the search module, it is more convenient to set the index at runtime based on the value selected in a drop-down
box.
Following is a simple example how to achieve this. A user control wraps the SearchBox control that is shipped with Sitefinity:
| .ascx |
 Copy Code |
|
<%@ Register Assembly="Telerik.Search" Namespace="Telerik.Search.WebControls"
TagPrefix="sitefinity" %>
<div>
<asp:DropDownList ID="IndexCatalogue" runat="server"
AutoPostBack="true" OnSelectedIndexChanged="SearchIndexes_SelectedIndexChanged"></asp:DropDownList>
</div>
<div>
<sitefinity:SearchBox ID="SearchBox1" runat="server"
ResultUrl="~/ResultUrlPage.aspx"></sitefinity:SearchBox>
</div>
|
| .ascx.cs |
Copy Code |
|
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.BindIndexCatalogue();
}
}
protected void SearchIndexes_SelectedIndexChanged(object sender, EventArgs e)
{
this.SearchBox1.IndexCatalogue = ((ListControl)sender).SelectedValue;
}
void BindIndexCatalogue()
{
this.IndexCatalogue.DataSource = IndexingManager.IndexingServices.Values;
this.IndexCatalogue.DataTextField = "Name";
this.IndexCatalogue.DataValueField = "Name";
this.IndexCatalogue.DataBind();
this.IndexCatalogue.Items.Insert(0, new ListItem("Please, select an index", string.Empty));
}

In order to use it as a public control and be able to add it to a Sitefinity page, this user control should be uploaded in the toolbox.
