What error? What happens when you run the code? What is happening in repeat() function? Where are you executing your command?

Solution 1

Are we getting the value inside txt_id field? It shouldn't be like Convert.ToString(txt_id.Text).

Use for loop rather then using the foreach.

foreach (RepeaterItem ri in repeater.Items)
{

CheckBox item_check = (CheckBox)ri.FindControl("item_check");
Label txt_id = (Label)ri.FindControl("txt_id");

if (item_check.Checked)
{

con = new SqlConnection(strcon);
cmd = new SqlCommand("ram", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@Action", "DELETE");
cmd.Parameters.AddWithValue("@eid", txt_id.Text);
try
{
con.Open();
cmd.ExecuteNonQuery();

}
catch (Exception ex)
{
ex.Message.ToString();
}
finally
{

con.Close();
}
}
}
repeat();
