how to refresh the gridview after it filters (Dynamic) using LinqDataSource ?

Question

AllowSorting="True" AutoGenerateColumns="False" DataSourceID="LinqDataSource1"> SortExpression="UserName" /> SortExpression="FullName" /> SortExpression="Email" /> SortExpression="LastLoginDate" DataFormatString="{0:dd MMMM yyyy}"/>

<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="MyDataContextDataContext" onselecting="LinqDataSource_Selecting">  
        <WhereParameters>  
           <asp:Parameter Name="Subject" /> 
        </WhereParameters>  
</asp:LinqDataSource> 

 public void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e)
        {
                this.LinqDataSource1.WhereParameters["Subject"].DefaultValue =  this.txtSubject.Text;
               e.Result = reporterRepo.GetInquiries(); 

Answer 1

Try using this, or modify it till it works. If I'm correct I did something like this before:

public void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
   this.LinqDataSource1.WhereParameters["Subject"].DefaultValue =  this.txtSubject.Text;
   GridView2.DataBind();
   e.Cancel = true;
}

Answer 2

my gridview was in updatepanel thats why it was not refreshing the gridview

 <asp:UpdatePanel....
