Redirecting URL with DList Linkbutton

[Isadore]

This is mainly a tip for beginners, and those looking at the DataList as an option. Its primary benefit is its nearly unlimited formatting capabilites --

In this example there is a DropDownList and a DataList. In the DataList, among various objects, is a linkbutton which functions to redirect the page based on the selected value in the nearby DropDownList.

Within the DataList structure the linkbutton as:

<asp:linkbutton
id=&quot;lnkSite&quot;
runat=server
Forecolor=&quot;red&quot;
Font-bold=&quot;true&quot;
CommandArgument=<%# Container.DataItem(&quot;AwwSiteCode&quot%>
OnCommand=commandHandler>
<%# Container.DataItem(&quot;AwwSiteCode&quot%>
</asp:linkbutton>

The OnCommand event is:

Protected Sub commandhandler(sender As Object, e As CommandEventArgs)
If ddChart.SelectedItem.Text = &quot;Chemistry Histories&quot; Then
Response.Redirect(&quot;ddChemHistory.aspx?AwwSiteCode=&quot; & e.CommandArgument)
ElseIf ddChart.SelectedItem.Text = &quot;Chemistry Real Time&quot; Then
Response.Redirect(&quot;ChemRT.aspx?AwwSiteCode=&quot; & e.CommandArgument)
ElseIf ddChart.SelectedItem.Text = &quot;Bacteria Histories&quot; Then
Response.Redirect(&quot;ddBacHistory.aspx?AwwSiteCode=&quot; & e.CommandArgument)
Else
Response.Redirect(&quot;BacRT.aspx?AwwSiteCode=&quot; & e.CommandArgument)
End If
End Sub

Where the &quot;e.CommandArgument&quot; completes the QueryString and the page is then properly redirected.

fyi
