See more:

In ASP.Net code-behind, I can set the controls (e.g. asp:Button) like this below:

C#

void setButtonStyle(Button btn)   {
    if (btn.Enabled)
        btn.Attributes.Add("style", "font-style:italic; font-weight:bold; background-color: #6bb642;");
    else
        btn.Attributes.Add("style", "font-style:normal; font-weight:normal; background-color: #81BEF7;");
}

In this page, there are also a couple of HTML buttons, how can these HTML buttons be set? Thanks.

Solution 1

Add runat="server" attribute to the HTML element to convert it to a server control.
now you can access the control from codebehind file

few examples:

ASP.NET

<input type="submit" id="btnInputTypeSubmit" runat="server" value="MyButton" />
       <button id="btnHTMLElement" runat="server">Button Control</button>

KB: Thanks for your response. My code for the HTML controls is similar to yours. For asp:Button, I can access to the button like void setButtonStyle(Button btn). But for HTML button, what is the type for the HTML button?

for btnInputTypeSubmit -> HtmlInputSubmit

for btnHTMLElement -> HtmlButton

In Code-Behind, the HtmlButton type is not recognized. Thanks.

The runat="server" does exist in the html. I have no problem to access to the HTML controls in code-behind. What I need is to have a general method to re-set the style of the HTML controls, in which it is needed to have general type for the HTML controls. Thanks anyway.

Solved by
void setHTMLControlStyle (System.Web.UI.HtmlControls.HtmlTableRow control, string sStyle) {
control.Attributes.Add("style", sStyle);
}
Thanks for your review and response.
