How do I put a hint/placeholder inside a asp:TextBox? When I say a hint I mean some text which disappears when the user clicks on it. Is there a way to achieve the same using html / css?
asp.net Solutions
Solution 1 - asp.net
placeholder
attribute
The You're looking for the placeholder
attribute. Use it like any other attribute inside your ASP.net control:
<asp:textbox id="txtWithHint" placeholder="hint" runat="server"/>
Don't bother about your IDE (i.e. Visual Studio) maybe not knowing the attribute. Attributes which are not registered with ASP.net are passed through and rendered as is. So the above code (basically) renders to:
<input type="text" placeholder="hint"/>
placeholder
in resources
Using A fine way of applying the hint to the control is using resources. This way you may have localized hints. Let's say you have an index.aspx file, your App_LocalResources/index.aspx.resx file contains
<data name="WithHint.placeholder">
<value>hint</value>
</data>
and your control looks like
<asp:textbox id="txtWithHint" meta:resourcekey="WithHint" runat="server"/>
the rendered result will look the same as the one in the chapter above.
Add attribute in code behind
Like any other attribute you can add the placeholder
to the AttributeCollection
:
txtWithHint.Attributes.Add("placeholder", "hint");
Solution 2 - asp.net
Just write like this:
<asp:TextBox ID="TextBox1" runat="server" placeholder="hi test"></asp:TextBox>
Solution 3 - asp.net
<asp:TextBox runat="server" ID="txtPassword" placeholder="Password">
This will work you might some time feel that it is not working due to Intellisence not showing placeholder
Solution 4 - asp.net
Adding placeholder attributes from code-behind:
txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);
Or
txtFilterTerm.Attributes["placeholder"] = "Filter" + Filter.Name;
Adding placeholder attributes from aspx Page
<asp:TextBox type="text" runat="server" id="txtFilterTerm" placeholder="Filter" />
Or
<input type="text" id="txtFilterTerm" placeholder="Filter"/>
Solution 5 - asp.net
asp:TextBox ID="txtName" placeholder="any text here"
