I am trying to have a webpage load into the web browser control in C# and I need all the radio boxes to already be set to no. I dont know how to tell the program to select those radios that are in the webpage and to then select yes or no to them.
How can I select those radios in the webBrowser control? using c Sharp

here is my code

<input type="radio" name="browser" value="IE" checked>
Internet Explorer<br>

<input type="radio" name="browser" value="Mozilla">
Mozilla<br>

<input type="radio" name="browser" value="Opera">
Opera<br>

推荐答案

使用checked属性:

Use the checked attribute:

<input type="radio" name="browser" value="IE" checked="true"></input>

参见此处以获取解释: W3Schools [
如果您需要在未选中任何一项的情况下，请添加无"单选框，或将其转换为复选框而不是单选框.

See here for explanation: W3Schools[^]

You can''t have all the radio boxes set to "no": that isn''t how radio buttons work. One of them is always set to true.

If you need a case when none of them are checked, either add a "None" Radiobox, or convert them to checkboxes instead of radio.

<input type="checkbox" name="browser" value="IE">Internet Explorer<br>
