I would like to add a default value for an asp textbox that looks like this
<asp:TextBox ID="Title" runat="server" CssClass="textEntry" ClientIDMode="Static"><xsl:value-of select="oohru/form/title"/></asp:TextBox>
Reason being is the page called is an xml page which loads this page as the stylesheet. The XML page once on the client side would transform that xsl select into the appropriate value [Which is an XML element from a previous cross page post].
Of course it ends up escaping it to look like
<input class="textEntry" id="Title" value="<xsl:value-of select="oohru/form/title"/>" name="ctl00$RightColumn$Title" type="text">
and the text box instead of having the value contained in the value-of select contains the actual value-select statement since it is escaped.
I tried setting the value in the pageload and got the same results and I tried turning off ValidateRequest neither worked.
Try
<xsl:value-of select="oohru/form/title" disable-output-escaping="yes"/>
Edit:
<asp:TextBox ID="Title" runat="server" CssClass="textEntry" ClientIDMode="Static"><xsl:value-of select="oohru/form/title"/></asp:TextBox>
To become:
<asp:TextBox ID="Title" runat="server" CssClass="textEntry" Text="{oohru/form/title}" ClientIDMode="Static"></asp:TextBox>

I am getting an error of "The server tag is not well formed" but I can't seem to figure out how to fix this exactly. The line it's breaking on is below.
<input type="checkbox" id="checkboxSoftware" runat="server" value='<%# Eval("Software")%>'<%# Eval("Software").ToString() == "Spotlight" ? " checked='checked'" : "" %>><%# Eval("Software") %><br />
I tried removing runat="server" and the page is displayed correctly but when I submit the form the repeater is on no data is stored. In my code behind I am using a control to concatenate the selections in my repeater but even when I select other checkboxes, that data is not getting into the database.
This worked before I tried to auto select the "Spotlight" checkbox on page load so it's something in this line of code that is causing the issue. Any help would be appreciated.
Can you try this?
<input type="checkbox" id="checkboxSoftware" runat="server" value='<%# Eval("Software")%>' checked='<%# Eval("Software").ToString() == "Spotlight" %>' /><%# Eval("Software") %>
I don't think you can evaluate values inside of a server tag unless you are setting an attribute and you had missed the closing tag for the input element.
Maybe I've forgotten how to use these, but I am going crazy trying to inject a server-side value into an HTML output. There are reasons why I am doing this inline, and not server-side, so please don't suggest that as a solution.
This code on the server side:
<asp:Label ID="Label1" runat="server" Text='<%= DateTime.Now.ToString() %>' />;
Renders as this in the client HTML sent to the browser:
<span id="Label1"> <%= DateTime.Now.ToString()></span>;
And it displays as big fat empty space, and nothing output to the interface.
If I change the ASP source to using the "#" character to define as data-binding syntax, then the rendered output to browser becomes:
<span id="Label1"></span>
EDIT:
Setting Label text was just a simplified object for the sake of asking the question. In real life, I am setting the CssClass attribute, which does not allow me to use the "wrapping" workaround some have suggested. I wanted to set a public property and have all the controls update from it dynamically on page load.
Ideally, since I already have all the controls laid out on the aspx page. Just looking to add an attribute. I wanted to have:
<asp:textbox ID='MyTxtBox1' CssClass='<% strVal1 %>' />
<asp:textbox ID='MyTxtBox2' CssClass='<% strVal1 %>' />
<asp:textbox ID='MyTxtBox3' CssClass='<% strOtherVal %>' />
<asp:textbox ID='MyTxtBox4' CssClass='<% strVal1 %>' />
Now what it looks like I need to do is repeat all my (250+) controls on the codebehind in a block of code that looks like:
MyTxtBox1.CssClass=strVal1
MyTxtBox2.CssClass=strVal1
MyTxtBox4.CssClass=strVal1
MyTxtBox3.CssClass=strOtherVal
I believe that may not work on a compiled Web Application as it's not interpreted at run-time like a C# "Web Site". However, I was able to get it to work wrapping the label around the value:
<asp:Label runat="server"><%= DateTime.Now.ToString() %></asp:Label>
Set the Label1.Text = value instead of trying to use server side attrs inside of the server control
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?
The placeholder attribute
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"/>
Using placeholder in resources
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");
Just write like this:
<asp:TextBox ID="TextBox1" runat="server" placeholder="hi test"></asp:TextBox>
<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
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"/>
asp:TextBox ID="txtName" placeholder="any text here"
I am having a problem with the asp.net multi line textbox
<asp:TextBox ID="Oohrl"
runat="server"
CssClass="textEntry"
ClientIDMode="Static"
Text="{/oohru/form/oohrl}">
</asp:TextBox>
This works fine with text= when the page loads it puts the appropriate value in there from the XML file
However the following does NOT do that
<asp:TextBox id="Description"
TextMode="MultiLine"
Columns="50"
Rows="4"
runat="server"
ClientIDMode="Static"
Text="{/oohru/form/desc}">
</asp:TextBox>
it just puts {/oohru/form/desc} as the literal text inside of the textbox. The multi line box renders as a textarea vs an input in the first example.
Below is how the xhtml is constructed on the browser
This is the one that works, where asdf IS the proper value that it should display
<input class="textEntry"
id="Oohrl"
value="asdf"
name="ctl00$RightColumn$Oohrl"
type="text">
This is the one that doesn't
<textarea id="Description"
cols="50"
rows="4"
name="ctl00$RightColumn$Description">
{/oohru/form/desc}
</textarea>
I did also try using my own textarea with runat="server" and another without that, it still won't put a value in . Is there a reason xslt won't render a value into a text area??
You can use Ajax TextBoxWaterMark Control to solve this issue. You need not use classes for this.
everything which you write in
double-course for text property, it
shown as default text for that ,so
you are getting like that

When I create a form, I try to make accessibility a top priority, but the output from asp .NET negates some of this. For example, when I set a label tag for an input tag, I create it a such:
<label for="frmFirstName">First Name<span class="required">*</span></label>
<asp:TextBox id="frmFirstName" CssClass="textbox" runat="server" />
But, when the HTML is output from the page, it is output as:
<label for="frmFirstName">First Name<span class="required">*</span></label>
<input name="ctl00$phMainContent$frmFirstName" type="text" id="ctl00_phMainContent_frmFirstName" class="textbox" />
This is a problem, as now the label is no longer tied to the input element. Is there a way to force .NET to output the exact id I set for the input field? I shouldn't have to use Javascript to correct something like this.
If you use ASP.Net 4 you can set the ClientIDMode attribute of the control to static. This will let it keep the value of the ID tag when rendered.
Use the asp:Label element and point its AssociatedControlId property to your textbox.
<asp:Label ID="lblFirstName" runat="server" AssociatedControlId="frmFirstName">First Name<span class="required">*</span></asp:Label>
<asp:TextBox id="frmFirstName" CssClass="textbox" runat="server" />
That should output the correct HTML for you.
In addition to the AssociatedControlId and <%= control.ClientId %> solutions, if your control (in this case, "frmFirstName") is guaranteed to be the only control with that ID on the page, then you can set the ClientIDMode property of the control to "Static", which will mean that ASP.NET will not munge the ID in the rendered HTML.
For example:
<label for="frmFirstName" runat="server" ID="lblFirstName">First Name</label>
<asp:TextBox runat="server" ID="frmFirstName" ClientIDMode="Static" />
will render as
<label for="frmFirstName" id="some$aspnet$id$lblFirstName">First Name</label>
<input type="text" id="frmFirstName" />
This will also make it easier if you happen to need to refer to it from Javascript, since it can be a pain to render ASP.NET's auto IDs in Javascript (as far as I know, it's impossible to do in a seperate .js file, you'd need to embed the JS on the page and use <%= control.ClientID %>).
See more about ClientIDMode here: http://msdn.microsoft.com/en-us/library/system.web.ui.control.clientidmode.aspx
You can use the ClientId property. This is what will be output as the control Id in HTML and what you can use client side to reference the rendered element:
<label for="<%:frmFirstName.ClientId%>">First Name<span class="required">*</span></label>
<asp:TextBox id="frmFirstName" CssClass="textbox" runat="server" /
Note:
<%:%> is new with ASP.NET 4.0 - you will need to use <%=%> if on .NET 3.5 and before.
Edit:
Just to add that ClientId is the way to go when referencing the control from Javascript.
