How to assign dynamic placeholder to Textbox?

I know this question is asked before for assigning text to textbox, but they didn't have answers or the given answers didn't work for me. I have a static function for translations and I'm trying to use that to assign a placeholder to a Textbox. How can I do it in aspx page?

My code is:

    <asp:TextBox ID="search" runat="server" 
    placeholder='<%# islem.DilGetir(7) %>'>
    </asp:TextBox>

This one returns this sourcecode:

<input name="ctl00$search" type="text" id="ctl00_search">

this code for multiselectbox choosen js and normal selectbox.

public void SelectFill(DataTable dtResult, HtmlSelect htmlSelect, string placeHolder, string textColumn, string valueColumn, string value)
    {
        htmlSelect.DataSource = dtResult;
        htmlSelect.DataTextField = textColumn;
        htmlSelect.DataValueField = valueColumn;
        htmlSelect.DataBind();

        bool isMultiple = false;
        foreach (var item in htmlSelect.Attributes.Keys)

            if (item.ToString() == "multiple")
            {
                isMultiple = true;
            }
        }

        if (isMultiple)
        {
            htmlSelect.Attributes["data-placeholder"] = placeHolder;
        }
        else

I experienced the same problem. The exact solution: Take all placeholder's text to hiddenfield component(separated with , ) and with JS, take the inside array hiddenfield text and assign to input text's placeholder attr with jQuery or JS.

You should set this attribute from the page code behind:

search.Attributes["placeholder"] = islem.DilGetir(7)
