(Found) the easiest way to bind dropdownlist in the gridview !!

Many people are asking how to bind dropdownlist in the <itemtemplate> In the gridview, that is, to read the Database Value and bind it to the dropdownlist control in the templatefield. I searched the internet for the write method in rowcreate or the BIND of the second read database field. simpler Method:
</ASP: templatefield>
<Asp: templatefield headertext = "locked?">
<Itemtemplate>
<Asp: dropdownlist id = "islock" runat = "server" Selectedvalue = <% # eval ("cateislock") %>>
<Asp: listitem text = "yes" value = "true"> </ASP: listitem>
<Asp: listitem text = "no" value = "false"> </ASP: listitem>
</ASP: dropdownlist>
</Itemtemplate>
</ASP: templatefield>
</Columns>

Note: The selectvalue attribute cannot be displayed on the ASPX page. If it is mandatory, it will be OK !!
