How to: Select Rows That Contain the Specified Value

• Dec 17, 2020

This example demonstrates how to select customers who live in the specified country.

An end-user types the country into the search box and clicks Search. The button editor’s ButtonClick event is handled to call the ASPxClientGridView.PerformCallback method.

This sends a callback to the server and generates the ASPxGridView.CustomCallback event passing it the country entered by the user. The CustomCallback event is handled to select the customers who live in the specified country.

C#

protected void grid_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e) {
    string country = e.Parameters.ToString();
    grid.Selection.UnselectAll();
    for (int i = 0; i < grid.VisibleRowCount; i++)
        if (grid.GetRowValues(i, "Country") != null)
            if (grid.GetRowValues(i, "Country").ToString() == country)
                grid.Selection.SelectRow(i);
}

VB.NET

Protected Sub grid_CustomCallback(ByVal sender As Object, ByVal e As ASPxGridViewCustomCallbackEventArgs)
    Dim country As String = e.Parameters.ToString()
    grid.Selection.UnselectAll()

    For i As Integer = 0 To grid.VisibleRowCount - 1

        If grid.GetRowValues(i, "Country") IsNot Nothing Then
            If grid.GetRowValues(i, "Country").ToString() = country Then grid.Selection.SelectRow(i)
        End If
    Next
End Sub
