Question

I am having this error, don’t know what seems to be the error.

“Cannot convert type ‘string’ to
‘System.Web.UI.HtmlControls.HtmlSelect’ via a reference conversion,
boxing conversion, unboxing conversion, wrapping conversion, or null
type conversion”

The code that causes the error above is as follows:

protected void RptFaqsAnswer_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    ...
    (e.Item.FindControl("myselect").ClientID as HtmlSelect).Items[0].Attributes.Add("display", "none");
    ...
}

In .aspx page I have this select tag as a child of a “repeater.”

<asp:Repeater ID="rptFaqsAnswer" runat="server" OnItemDataBound="RptFaqsAnswer_ItemDataBound">
    <select runat="server" id="myselect">
        <option value="c1">Choice 1</option>
        ...
    </select>
</asp:Repeater>

What seems to be the reason of this error.

Thanks

Answer 1

Try this

e.Item.FindControl("myselect") as HtmlSelect

instead of

e.Item.FindControl("myselect").ClientID as HtmlSelect

It was the ClientID you were trying to convert which is why you were getting the error
