I want to add child object to a TextBox, but this code gives an error
How can I achieve this?
<asp:TextBox ID="TextBox2" runat="server">
<asp:Label runat="server" Text="Label"></asp:Label>
</asp:TextBox>`
TextBox and Label are two different controls. You cant nest a Label inside a text Box.
Eg:
<asp:Label runat="server" Text="Label"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server"> </asp:TextBox>
What do you want to do here?
As there are some of the ASP.NET controls like Linkbutton which allows you to hold HTML controls inside them
<asp:LinkButton ID="lnkDelete" runat="server" CssClass="remove">
<span><font color="#fb4202">x</font> Remove</span>
</asp:LinkButton>
but it is not possible to hold a asp:Label in a asp:Textbox control
What you are trying to do is impossible. While WPF has a framework that enables this kind of things, HTML and thus ASP.NET does not.
If you are trying to set the text, try this:
<asp:TextBox ID="TextBox2" runat="server" Text="abc" />
Else, just put them side by side:
<asp:Label runat="server" Text="Label" />
<asp:TextBox ID="TextBox2" runat="server" />
Textbox is a Editable Control and Label is non-Editable Control, so you can't put Label inside TextBox. You can Put Label Just Before The Textbox as :
<asp:Label ID="Label1" runat="server" Text="Enter Text"><asp:Label>
<asp:TextBox ID="txtValue" runat="server"/>

I want to palce a asp.net label over asp.net image
<asp:Image ID="Image1" runat="server" ImageUrl="~/option.PNG" />
<asp:Label ID="Label1" runat="server" Text="Labelsssssss"></asp:Label>
here it will come one after another only. I have to use both asp controls no html controls are allowed.How?
if possible, remove the image, put the label in a div, set the background-image of the div to your image.
<asp:Panel runat="server" ID="pnl">
<asp:Label runat="server" ID="lbl" Text="this is text" ForeColor="Red"></asp:Label>
</asp:Panel>
CS page:
pnl.Attributes.Add("style", "background:url(/option.PNG)");
I created an uneditable control in asp.net using either of the folowing
<asp:TextBox ID="txtStartDate" runat="server" enabled="false"></asp:TextBox>
or
<asp:TextBox ID="txtStartDate" runat="server" readonly="true"></asp:TextBox>
am using a javascript popup to fill the textbox in the client side. the value is always null when i tried to retrieve it in codebehind
can anyone suggest a better way
Try this
<asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox>
Code Behind
txtStartDate.Attributes.Add("readonly", "readonly");
Read more about How to retrieve read-only textbox's value in the code behind
<asp:TextBox ID="txtStartDate" runat="server" readonly="true"></asp:TextBox>
you can use this way
txtStartDate.Text = Request.Form[txtStartDate.UniqueID];
I have a lot of textboxes on submit page and all have a validator. I want to control them with a submit button which is on master page. It works but other buttons also cause validation. validation summary is always shown either submit button is clicked or any other buttons. how can I control this situation? (asp.net)
for each individual submit use "ValidationGroup". here is the sample:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="TextBox1" ValidationGroup="Submit" ID="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="TextBox2" ValidationGroup="Submit" ID="RequiredFieldValidator2" runat="server" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
<asp:Button ID="Button1" ValidationGroup="Submit" runat="server" Text="Button" />
I think you can resolve this by using ValidationGroup Property..

Apologies for the newbie question. My client wishes me to make a small change to the gridview on his http://www.flogitdonegal.com/SearchPage.aspx page.
Note the way the Title column is a hyperlink to view more information. This comes from a 'BriefDescription' field in the database.
How can I add 250 chars from the 'FullDescription' underneath the Title in the same cell, but I dont want it be a hyperlink.
Essentially it will be 2 fields coming into the same column.
Thanks in advance for all help.

If this is using a GridView you are most likely using a TemplateField as it is to display the HyperLink.
Within the ItemTemplate of the TemplateField you can specify an additional Label underneath using something as follows:
<asp:Label runat="server" id="FullDescLabel" Text='<%# DataBinder.Eval(Container.DataItem, "FullDescription") %>' />
You need to use the TemplateField and here is a tutorial that explains some of the other fields that GridView offers as well.
<asp:GridView ID="gvwCompounds" runat="server" DataSourceID="objItemsFromYourDB">
<Columns>
....
<asp:TemplateField>
<ItemTemplate HeaderText="Title">
<asp:HyperLink runat="server" ID="Hperlink1" NavigateUrl='<%# Eval("BriefDescriptionUrl") %>' Text='<%# Eval("BriefDescription") %>' />
<br />
<asp:Label runat="server" ID="Label1" Text='<%# Eval("FullDescription") %>' />
</ItemTemplate>
</asp:TemplateField>
....
</Columns>
</asp:GridView>
I'm trying to separate my presentation and logic as much as I can, but there's one problem.
How can i set the text-property to a dynamic value from my design file? I want to do like this:
<asp:Textbox id="txtUrl" runat="server" Text="<%= user.URL %>" />
But this will fail. Am i forced to do this from code behind?
<asp:Textbox id="txtUrl" runat="server" Text="<%# user.URL %>" />
It's all about the #. but it won't get set till txtUrl.DataBind() or something higher in the object heirarchy (like the Page) calls DataBind().
How about this :
<input type="text"
id="txtUrl" name="txtUrl" runat="server"
value='<%= user.URL %>' />
You can use binding instead of evaluation.
This code binds a text box's Text property to a user's Url property returned by MyData.GetLoggedInUser(). This allows for 2-way binding.
<asp:FormView ID="UserView" runat="server" DataSourceID="LoggedInUser">
<ItemTemplate>
<asp:TextBox ID="tb"
runat="server"
Text='<%# Bind("Url") %>'></asp:TextBox>
</ItemTemplate>
</asp:FormView>
<asp:ObjectDataSource ID="LoggedInUser"
runat="server"
SelectMethod="GetLoggedInUser"
TypeName="MyData">
</asp:ObjectDataSource>
