Add custom attribute to an HTML input element with C# [duplicate]

Adding custom attributes to an asp:CheckBox control (2 answers)

Closed 7 years ago.

I'm using the following method to add a custom attribute to a check box:

CheckBox chkBx = new CheckBox();
chkBx.ID = "chk" + n;
chkBx.Attributes["itemname"] = strtemPath;

But as a result I'm getting the following HTML:

<span itemname="Some folder"><input id="MainContent_chk0" type="checkbox" name="MasterPg$MainContent$chk0" /></span>

where I'm expecting this:

<input id="MainContent_chk0" type="checkbox" name="MasterPg$MainContent$chk0" itemname="Some folder" />

Any idea how to correct the C# code to get my expected result?

chkBx.InputAttributes.Add("itemname", strtemPath);

Try:

chkBx.Attributes.Add("itemname", strtemPath);
