Can you do something like :
<%# DataBinder.Eval(Container.DataItem,"Column1").ToString().Replace("_",<%# DataBinder.Eval(Container.DataItem,"Column2") %> %>
Can a DataBinder.Eval be nested within another DataBinder.Eval?
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?
View 2 RepliesI have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :
[code]...
As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.
I've a asp.net linkbutton inside asp.net repeater control which renders multiple link buttons. I want to set the style of each and every linkbutton dynamically.
I'm trying
style="color:#6D7B8D;font-size:<%# DataBinder.Eval(Container.DataItem, "Title")%>;"
But i'm getting "The server tag is not well formed" error.
I have the following object:
CrossTabDataObject
{
string RowName{get;set;};
int RowId{get;set;}
List<string> CellContents = new List <string>();
//Constructor..... etc.
}
I'm building a dynamic crosstab grid using GridView in asp.net 3.5
I wish to bind to CellContents[0] for dynamic column 1, CellContents[1] for dynamic column 2 (dynamic column 0 is the RowName field from the CrossTabDataObject) etc. I am using:
object boundValueObj = null;
Control ctrl = (Control)sender;
IDataItemContainer dataItemContainer = (IDataItemContainer)ctrl.NamingContainer;
boundValueObj = DataBinder.Eval(dataItemContainer.DataItem, strSelectedID);
This code is in the InstantiateIn function of the gridview as I'm creating drop down list templates in each cell of the crosstab.
I have code (not shown) that sets strSelectedID depending on the column being created.
When strSelectedID is equal to "RowName" for dynamic column [0] the DataBinder.Eval function works fine and sets boundValueObj as expected. The problem comes when strSelectedID is set to "CellContents[n]" where n is the Column Index.
DataBinder.Eval only works with properties and fields of objects. How do I get around this?
I am trying to access column value by using DataBinder.Eval on RowCommand event of Gridview. It always return NOT SET TO ANY INSTANCE error for eveytime. I know how to do this by employing a label control in ItemTemplate, but am trying to find a way to bypass.
Error returned by DataBinder.Eval(row.DataItem, "LinkToInvoice").ToString

I have a hiddenfield in my datalist .....and its databinded like this
<asp:HiddenField ID="SecondLevelCategory" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "SecondLevelID") %>' />
the problem arise when this datacolumn in my database have a null value, it throws an error ....how can I get this to work so that DataBinder.Eval can take a null value?
i have one hidden field and i want to bind it with two values of my data base separated by an coma. some thing like
->asp:HiddenField ID="hfRstidDate" runat="server" Value=<%# DataBinder.Eval(Container.DataItem, "tsk_ID"),DataBinder.Eval(Container.DataItem, "Date_Worked").ToString())%>
<asp:Label ID="lbl_date" runat="server" Text='<%# Convert.ToDateTime(Eval("dt_pub")).ToString("dd/MM/yyyy") %>'
check for systax error
It show me server tag not well formed error
Do you know why it's FALSE
when I check the value from DataBinder.Eval(Container.DataItem, "Type") i've "Checkbox" so I wonder what is wrong there?
I have the code below that works fine, but I need to have more than one field using the same command.

I'm working at the aspx page, and the following code is inserted in a Repeater control:
<%# ((System.Collections.Generic.List<double>)DataBinder.Eval(Container.DataItem, "BookPrices")).Max() %>
Brings up the following error: 'System.Collections.Generic.List<double>' does not contain a definition for 'Max'
List does have an method of Max(), so I'm possibly messing up my code somehow. What is my problem?
BookPrices is a list<double> object, which I'd like to print it's maximum value.
I am using Repeater to display the data.
to get the data from database i am using
<%# DataBinder.Eval(Container.DataItem, "datafield") %>
when i build it... it build successfully but in error list i found
Name 'DataBinder' is not declared.
I am getting error when i write the belwo code in the code behind.
Error: The name DataIem Does not exist in the context
protected void getHotDeals()
{
D4T.tbDealDataTable dealTable;
dealTable = dealTA.HotDeals();
StringBuilder sb = new StringBuilder();
[Code]....
I try to pass two parameters to code behind
Into gridview
Visible='<%# Show(DataBinder.Eval(Container, "DataItem.Id").ToString()) %> + <%# MostrarBotonBorrar(DataBinder.Eval(Container, "DataItem.Rol").ToString()) %>'
in codeBehind:
public bool Show(string value,string value2)
{
if(value == LbluserInvisible.Text)
{
return true;
}
else
{
return false;
}
}
I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
something like CallbackFunc(Eval("SomeField"));
i need to get data-bound items from outer listview to display in inner Listview, in this scenario:
[code]....
Where the higlighted text mean the title for outer datasource.
i have small problem with my code in vb.net that i want to use (Eval) in my project
so i write this code :
<asp:Label ID="Label1" runat="server"
Text='<%#Eval("PAG_PAGES") == null ? "" : ((PostAgenciesModel.PAG_PAGES)(Eval("PAG_PAGES"))).PAGE_TITLE_AR %>' />
and this code i used in my C# project .... all want to show the (Label1) in inside my GridView....
("PAG_PAGES") is the name of table..
PostAgenciesModel is the edmx...
PAGE_TITLE_AR is the colum in ("PAG_PAGES") that i want to show it
I have such code:
<%# (int)Eval("Favorites") > 0 ? "<a href="history.aspx?visitorid=<%# Eval("VisitorID") %">Favorites</a> / " : ""%>
where I show a link if value>0 .. However it gives me a bad url(history.aspx?visitorid=%3C%#%20Eval) when I put visitorID=<%#...%>inside another Eval<%#..%>
I'm trying to do the following for asp.net combobox:
Text='<%# IIf(Eval("Name").ToString().Equals(""), Bind("Other"), Bind("Name") %>'
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column. Anyone know the right syntax, keep getting object not set to reference. I'm doing this in VB.Net.
if you have two table inner join like SELECT* From A INNER JOIN B on A.ID = B.IDSay A and B tables both have Username values but A's username is Test, and B's username is Test2When I do Eval("Username") it always print out "Test", how can I configure it to print out "Test2"... meaning how to specify which table's value to put using eval.. is there something like Eval(B.("Username"))??
View 6 RepliesWhat I am trying to achieve is to use an Eval as parameter in my anchor tag's href. The anchor is nested inside a repeater, why I cannot use the code behind to achieve this.
I have tried a few things without any luck.
<a href="http://MyWebsite/ActiveUsers?ID=InsertEvalHere"><%# Eval("Name")%></a>
The following code below is what I have tried to do:
<a href="<% "http://MyWebsite/ActiveUsers?ID=" + DataBinder.Eval(Container.DataItem("ID"))%>"><%# Eval("Name")%></a>
<a href="<% "http://MyWebsite/ActiveUsers?ID=" + Eval("ID")%>"><%# Eval("Name")%></a>
<a href="http://MyWebsite/ActiveUsers?ID=<% DataBinder.Eval(Container.DataItem("ID"))%>"><%# Eval("Name")%></a>
<a href="http://MyWebsite/ActiveUsers?ID=<%# Eval("ID")%>"><%# Eval("Name")%></a>
None of the above seemed to be right, as I keep getting this error - The tag is not well formed.
How should I handle this?
I am trying to Navigate URL in this way
<asp:HyperLink runat="server" NavigateUrl='javascript:NavigateUrl("<%#Eval("TicketID")%>","<%=RedirectURL %>");'><%# Eval("TicketID") %></asp:HyperLink>
but an error occurred in the javascript Error Console in Mozilla browser. Error: missing ) after argument list Source File: javascript:NavigateUrl("<%#Eval("TicketID")%>","<%=RedirectURL%20%>");
Line: 1, Column: 22
Source Code: NavigateUrl("<%#Eval("TicketID")%>","<%=RedirectURL %>");
I want to remove the error. but functionality is ok.
Can I use variable in eval in repeater? Or how can I use it?
For example:
<%# DataBinder.Eval(Container.DataItem, lngHome) %>
Code behind in form load:
[code]....
I have 2 fields in database table: eng_detail and tr_detail
So how can I use like this <%# DataBinder.Eval(Container.DataItem, lngHome) %>?
I have a dropdownlist that gets data through entity objects, but with a navigation. But I get an error trying to do this.
<asp:DropDownList ID="ddlVacancy" DataValueField="ID" DataTextField='<%# Eval("Position.Name") %>'
