SUMMARY

The current page index of the SmartDBView form can be controlled with a textbox. This can be achieved in two ways - either with a customized SmartPager or directly using the SmartDBView.RowIndex property which is similar to the FormView.PageIndex property.

Using SmartPager

1. In Design mode, open SmartPager smart-tag panel and select the Create Numeric Template or Create DropDownTemplate command.
   
2. Select the Edit Templates command and drag-and-drop a textbox and a button control from the toolbox into the PagerTemplate frame.
   You can also add an Integer RangeValidator to validate the textbox value.
   
3. In addition set the new button's properties respectively - CausesValidation=false UseSubmitBehavior=false CommandName="Page".
   The CommandName="Page" designates the button as a paging button. The CommandArgument should be assigned dynamically by using the TextBox's value. You can find more information about the available command names in the documentation - SmartPager Class
   The new mark up will look something like this:
   

   <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
   <asp:Button ID="Button1" CausesValidation=false UseSubmitBehavior=false 
           CommandName="Page" runat="server" OnClick="Button1_Click" Text="Go" />

   
   
4. Double click the button to create an OnClick event handler. The event handler have to extract the page number from the TextBox and set it as a CommandArgument for the button. The code will look like this:
   

   protected void Button1_Click(object sender, EventArgs e)
   {
       Button button = (Button)sender;
       TextBox txtPageNumber = (TextBox)button.NamingContainer.FindControl("TextBox1");
       button.CommandArgument = txtPageNumber.Text;       
   }

Using SmartDBView.RowIndex

protected void btnPage_Click(object sender, EventArgs e)
{
    // RowIndex is zero based
    SmartDBView1.RowIndex = Math.Max(0, int.Parse(txtPageNumber.Text) - 1);
}
