What causes the fluctuation in height when I place my control on the panel?

After adjusting the height of a textbox with CSS, I noticed that when placed inside a Panel element, the height reverts back to its previous setting. How can I resolve this issue and keep the height stable?

Here is my HTML code:

<asp:Panel ID="panelPost" runat="server">
<asp:TextBox ID="TxtNumPost" CssClass="TxtNamePost" runat="server"> </asp:TextBox>
</asp:Panel>

This is my CSS code:

.TxtNamePost {
     Height: 30%;
}

It's worth mentioning that using height: 30px works perfectly fine, but I specifically need it to be in percentage form.

Answer №1

It is possible that there are two different issues at play here.

  1. One potential problem could be related to using a height of 30% in your CSS. Keep in mind that when you set a height in percentage, it is relative to the parent element. Therefore, if you move an element within another container (like a panel), the parent element changes and this can cause unexpected behavior.

  2. Another issue might be with .NET changing the ID of your textbox after moving it inside the panel. You can check the new ID by inspecting the source code of your webpage - it may appear as something like 'panelPost_TxtNumPost'. To prevent this from happening, consider setting the 'ClientIDMode=static' on the Textbox.
