Forms Data Controls :: Using Custom Text Before Eval?

Mar 4, 2011

I have a repeater that has been given a datasource from my database containing pictures. The problem is that when i create and log a user into my site i send him to a folder that has no access from others than the ones with a roles called User. When he creates his profile, he uploads a picture which is saved in the same folder "User/picture/picturename" and in the database "picture/picturename".

Now i need to pull this picture to the Default page page where users are not logged in. If i add an Image Control to the frontpage with ImageUrl='<%#Eval ("PictureThumbURL") %>' it tries to pull out the picture from the folder User which is obvious that it can't since it lacks the User/ in front.

Is it possible to get this picture by manually adding User/ to the ImageUrl='<%#Eval ("PictureThumbURL") %>' and if so, how?

C# - Getting Eval To Work In A Databound, Templated Custom Control?

Sep 29, 2010

Context

I'm putting together a templated, databound control. Presently it works with the following syntax...
<cc:ItemChooserControl ID="ItemChooser" runat="server">
<TitleTemplate>
<h4><%# DataBinder.Eval(Container.DataItem, "DisplayName") %></h4>
</TitleTemplate>
</cc:ItemChooserControl>

Problem

What I would like though is that the shorter, simpler Eval would work instead.
<h4><%# Eval("DisplayName") %></h4>
What I get however when using straight Eval is an error:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

Code

I'm databinding to a custom HtmlTableCell...
public class TitleTemplateTableCell: HtmlTableCell, INamingContainer
{
private object m_DataItem;
public virtual object DataItem
{
get { return m_DataItem; }
set { m_DataItem = value; }
}
}

With the following custom DataBind (non-related code removed)...

foreach (object dataItem in dataSource) {
TitleTemplateTableCell title = new TitleTemplateTableCell();
TitleTemplate.InstantiateIn(title); // TitleTemplate is the template property
title.DataItem = dataItem;
title.DataBind();
}

Forms Data Controls :: Use Eval Or Bind In A Databound Control?

Sep 8, 2010

I have a repeater I've databound with a generic arraylist from a LINQ query (.ToList() ) in the code behind.

I was using

<%# Bind("FirstName")%> but noticed
<%# Eval("FirstName")%> works just as well.

Is it better to use Eval or Bind? or does it depend on the situation?

Forms Data Controls :: Getting A Boolean Response From An Eval Operator?

Oct 18, 2010

I would like to use an eval stmt to return a true/false for the visible property of a HyperLinkField. IF clientComment exists, I would like it to return True, if clientComment is null or "", then would like it to return False.

By default I noticed it already will not show the hyperlink if clientComment is Null, however the bug I'm running into is if the client enters a comment but then later deletes it so it's not null but blank, or "", in which case the HyperLinkField will incorrectly display. Here's my attempt so far but I'm obviously hitting a wall:

Visible='<%# Eval("clientComment")==Null or =="",False) %>'

Forms Data Controls :: Control Parameter EVAL From A Formview Item

Aug 31, 2010

I have a Formview ('formview1') with a pager. I also have a gridview ('gridview1') linked to a SQL datasource ('History'). I need to set the SelectParameter ('Serial') of the datasource to be the value of a field on the current page in the formview. The value i need to get is in the ItemTemplate and is a label called 'SerialNumberLabel'. So, something like:

<SelectParameters>
<asp:ControlParameter Text = "Eval fromview1.currentpage.itemtemplate.SerialNumberLabel" >

I also need to ensure that the SQL source and gridview rebind when the pager is activated.

Forms Data Controls :: Programmatically Change ItemTemplate Eval Statements?

Dec 21, 2010

I have a GridView with an TemplateField:

<asp:GridView runat="server" ID="gvReport" ondatabinding="gvReport_DataBinding">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("answers") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions") %>' />
</ItemTemplate>
</asp:TemplateField >
</Columns>
</asp:GridView>

What I'd like to do on gvReport_DataBinding is change the field the Evals point to, so I end up with something like:

<asp:Label runat="server" Text='<%#Eval("answers_foo") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions_foo") %>' />

I have gotten this far:

TemplateField tf = ((TemplateField)gvReport.Columns[0]);

But I'm not sure what I should be doing with tf. tf.SomeProperty.Replace("answers", "answers_foo")?

Or am I barking up the wrong airplane on this one?
