Please let me introduce myself. My name is Jackie Sun. I’m a programmer from Beijing, China.

After I read this article about how to Customize SearchBoxEx, I think it is very very helpful for the beginer to learn how to reuse all the logic of SearchBoxEx and provide new render logic, like me. Then, I run the code on my server, it works successful. Thanks for your share!

Now, I’m working hard for SharePoint Web Part Development. The main job is customize the search interface in SharePoint with Fast For SharePoint Server. But the official examples is little, so I want to consult you.

The problem is how to add a time select control in the search box. Like diagram 1.

The original SharePoint search box is like diagram 2.

In past two days, I tried to do some customization, but I can’t deliver the value of the time select control to the search result as parameter.
I’m trying to add a DropDownList control, then add SelectedIndexChanged event process procedure code. All codes is following:

Code:
public class MySearchbox : SearchBoxEx {
…
DropDownList timeSelect;

protected override void CreateChildControls()
{
base.CreateChildControls();

Table searchBoxTable = base.Controls[0] as Table;
TableRow searchBoxTableRow = searchBoxTable.Rows[0];
TableCell timeCell = new TableCell();

timeSelect = new DropDownList();
timeSelect.EnableViewState = false;
timeSelect.Items.Add(new ListItem(“Last 3 Year”));
timeSelect.Items.Add(new ListItem(“Last 3 month”));
timeSelect.Items.Add(new ListItem(“Last 3 week”));
timeSelect.Items.Add(new ListItem(“Last 3 day”));
timeSelect.SelectedIndexChanged += new EventHandler(timeSelect_SelectedIndexChanged);

timeCell.Controls.Add(timeSelect);
searchBoxTableRow.Cells.AddAt(1, timeCell);
}

// Response for SelectedIndexChanged Event
void timeSelect_SelectedIndexChanged(object sender, EventArgs e)
{
base.AppQueryTerms = “I DON’T KNOW HOW TO SET IT.”;
base.AppendToQuery = false;
}

…
}

I think I should pass the arguments by setting AppQueryTerms, but I don’t know how to set it. The program is failed, so I can’t get any search results.

Is this idea wrong? Do you have some good suggestions?

Thank you very much.

Yours
Jackie Sun
