can you show us some of your code that you have tried ? Did you tried to find the user control on Data Bound event of the repeater ? show your code, so that we could guide you easily.

int index = 0;

It explains your issue.
I also feel like you got the ItemDataBound event all wrong.

C#

protected void Repeater2_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType != ListItemType.Item
                && e.Item.ItemType != ListItemType.AlternatingItem)
            {
                return;
            }


            UserControl u = (UserControl)e.item.FindControl("SubChemicals1");

            if (u != null)
            {

                    DropDownList d = (DropDownList)u.FindControl("ddlchemicals");
                    d.DataTextField = "CName";
                    d.DataValueField = "RecID";
                    d.DataSource = bl.Fill_DDL("Sp_GetSubChemicals");
                    d.DataBind();
                    d.Items.Insert(0, new ListItem("---Select---", "0"));


            }


        }

Hi Subhan, Please try with this code

<pre lang="c#">protected void Repeater2_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType != ListItemType.Item
                && e.Item.ItemType != ListItemType.AlternatingItem)
 UserControl u = (UserControl)e.item.FindControl("SubChemicals1");

            if (u != null)
            {

                    DropDownList d = (DropDownList)u.FindControl("ddlchemicals");
                    d.DataTextField = "CName";
                    d.DataValueField = "RecID";
                    d.DataSource = bl.Fill_DDL("Sp_GetSubChemicals");
                    d.DataBind();
                    d.Items.Insert(0, new ListItem("---Select---", "0"));
             }

        }</pre>
