How do I dynamically remove items from the checkboxlist

Question

I have a CheckBoxList which is bound by an SqlDataSource control. I want to remove some items from that list according to some conditions when the page loads.

Multiple options:

change the SelectCommand accordingly
use cbl.Items.Remove(item) or cbl.Items.RemoveAt(index)

I tried the second option (cbl.Items.Remove(item)). But somehow it is not working. The items are still there. Where do I add that code? I had added it in the Page_Load function. – Khushali bhangde Feb 17 '16 at 17:24

Your SqlDataSource should have a selectCommand which references parameters:

SELECT * FROM [tag] where ([name] like @nameFilter)

You can then set the values for those parameters:

 protected void Page_Load(object sender, EventArgs e)
     {
            SqlDataSource1.SelectParameters.Add("nameFilter", "value");
            FormView1.DataBind();
     }
