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.
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?
View 2 RepliesCan 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?
I 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 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 want to do something like this, haven't been able to make it work, I can't get the code syntax right on the style attribute of the div tag:

Maybe it wont ever work and I must find another way?
Server control code:
<asp:RequiredFieldValidator ID="RequiredFieldValidatorOnlineID" runat="server" ControlToValidate="TextBoxOnlineID" ErrorMessage="Online ID is required.<br />" ToolTip="User Name is required." SetFocusOnError="True" Display="Dynamic" CssClass="validationerror"></asp:RequiredFieldValidator>
Rendered Server control code:
<span id="ctl00_ContentPlaceHolderSYLMainMaster_RequiredFieldValidatorOnlineID" title="User Name is required." style="display:none;">Online ID is required.<br />
I have tried the following to remove the style attribute with no luck:
RequiredFieldValidatorOnlineID.Attributes.Remove("style")
and
RequiredFieldValidatorOnlineID.Attributes.Clear();
I don't need and want the style attribute, how can I prevent it from being written into my code? It messes up the alignment of the error message with my textbox.
how can i set style attribute in code behind c#?
View 2 RepliesI noticed that the style attribute od <div runat="server"> is rendered CammelCase (first letter upper case, i.e. "Style") when I data-bind it.

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.
My <style> for thumbnails currently looks like this:
<style type="text/css">
img.TN {
width: 100%;
margin-bottom: 5.294%;
cursor: pointer; }
</style>
This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are.
I'm using ASP.NET 2.0, and CSS 2.0
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.
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" onchange="calculate()" runat="server" Text="0"></asp:TextBox>
