ASP.NET VB GridView search display on alternate page in Sharepoint 3

Currently, I have a simple GridView search setup on a page within my Sharepoint site. It's very basic (code is attached).

What I need to do is have a small web part on the home page with a small search field and a search button that displays the results on the existing search page. I'm not sure what the easiest way to accomplish this is since my current search does not use query strings.

I'm up for any recommendations. Thanks.

Hi,

I change your logic to programatically clear / add the filer parameters instead of declaratively specifying them. That way you can easily implement logic to manage a search string coming in through a querystring as well. I have not made any changes to your declarative code/markup apart from removing the declared eventhandler (as it is no longer used and also removed from the script block). What you do now is to point to your original search page and just append ?searchString=whateveryouwanttosearchfor. So if you want to implement a small web part with a search field and a button simply so something like the below in the click eventhandler:

Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSearch.Click
    Response.Redirect("~/YourSearchPage.aspx?searchString=" & txtSearch.Text)
End Sub

/Carl.
<script runat="server">
    Dim SearchString As String = ""

    Protected Sub btnClear_Click(ByVal sender As Object, ByVal e As  _
            System.EventArgs)
        ' Simple clean up text to return the Gridview to it's default state
        txtSearch.Text = ""
        SearchString = ""
        VWvisProjects.FilterParameters.Clear()
        VWvisProjects.FilterParameters.Add("projectno", SearchString)
        VWvisProjects.FilterParameters.Add("name", SearchString)
        VWvisProjects.FilterParameters.Add("fullnumber", SearchString)
        VWvisProjects.FilterParameters.Add("ProjManagerName", SearchString)
        VWvisProjects.FilterParameters.Add("PrincipalName", SearchString)
        Gridview1.DataBind()
    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Page.IsPostBack Then
            If Not Request("searchString") Is Nothing Then
                Dim p As String = Request("searchString").ToString()
                VWvisProjects.FilterParameters.Clear()
                VWvisProjects.FilterParameters.Add("projectno", p)
                VWvisProjects.FilterParameters.Add("name", p)
                VWvisProjects.FilterParameters.Add("fullnumber", p)
                VWvisProjects.FilterParameters.Add("ProjManagerName", p)
                VWvisProjects.FilterParameters.Add("PrincipalName", p)
                GridView1.DataBind()
            End If
        Else
            SearchString = txtSearch.Text
            VWvisProjects.FilterParameters.Clear()
            VWvisProjects.FilterParameters.Add("projectno", SearchString)
            VWvisProjects.FilterParameters.Add("name", SearchString)
            VWvisProjects.FilterParameters.Add("fullnumber", SearchString)
            VWvisProjects.FilterParameters.Add("ProjManagerName", SearchString)
            VWvisProjects.FilterParameters.Add("PrincipalName", SearchString)
            GridView1.DataBind()
        End If
    End Sub
</script>

Perfect.

The web part would not take the VB code in the page so I just added a little JavaScript snippet to run the query string instead.


function gosearchCon() {
    var SearchString = document.forms['aspnetForm'].txtSearch;
    window.location = "Projects/default.aspx?SearchString=" + SearchString.value;
}

function checkEnter(e) {
    var characterCode
    var SearchString = document.forms['aspnetForm'].txtSearch;
    if (e && e.which) {
        e = e
        characterCode = e.which
    }
    else {
        e = event
        characterCode = e.keyCode
    }

    if (characterCode == 13) {
        window.location = "Projects/default.aspx?SearchString=" + SearchString.value;
        return false;
    }
    else {
        return true
    }

}
