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?
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?

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.

<asp:HiddenField ID="SecondLevelCategory" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "SecondLevelID") %>' />

I'm trying to populate the DataPager using Container.DataItem (I'm not allowed to use FindControl) but I get this error
'System.Web.UI.WebControls.DataPager' does not contain a definition for 'DataItem' and no extension method 'DataItem' accepting a first argument of type 'System.Web.UI.WebControls.DataPager' could be found (are you missing a using directive or an assembly reference?)

I want to acces Container Dataitem in <%.
Is it possible to do that?
I want to pass the current dataitem to a method and check if it's valid then show a button.
This <% %> is located inside a repeater.
<%
if (Validate( (Order)Container.DataItem))
{ %>
<asp:button text=edit>
<% }%>
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?
input type=..... value="<%= ISO3166CountryList.GetCountryByCode("IE", CurrentLocale).Name %>" />
I'm looking to replace the hardcoded IE with something like
<%#(Container.DataItem as PhoneNumber).ISO%>
No variations of what I've tried worked. How can I get a databinded value when within a <%= code block? Do I need to use an intermediary variable?
<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
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?

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 a
<%# DataBinder.Eval(Container.DataItem, "starttime") % >
i.e. starttime is field in mysql which i bind to asp:Repeater. and want to print as <span>Start Time:
<%# DataBinder.Eval(Container.DataItem, "starttime") %> </span>
if starttime is not blank ..and if blank, print nothing.. How to do this in asp.net ...
I have a ListView in which i have a function that creates images for users. I pass userGender,userImage1name,userIsImage1Aprooved values to the function in which i generate image.ie. if user has approved image i return it back, otherwise i return default image based on gender.y question is, is there any way to avoid passing 3 parameters to that function and to pass whole DataRow so i can get values of columns i need?In reality i pass about 12 parameters just made it easy for you.ie. i want to achieve something like that <%# GetImage(Container.Item) %> while in GetImage() i would be able to access Item("some_column_name") or C# version Item["some_column_name"].
View 2 RepliesI'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 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())%>
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
CODE BEHIND:
[Code]....
[Code]....
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkRDR1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>

Dim checkbox As CheckBox = CType(row.FindControl("chkRDR1"), CheckBox)
I'm trying to pass a string value to a javascript function from a LinkButton's OnClientClick event, but the function is receiving "<%# Container.DataItem %>" instead of the value. Here's the code:
OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');"
The container is a collection of strings. Why is it not evaluating?EDIT: This is located in a nested ListView. The datasource for the inner ListView is a property in the datasource of the outer ListView.
I a using Gridview bind to a dataset. For this example, I am only setting up two columns.
1. Edit button
2. A template field that will display "No" and in Edit mode will show a checkbox.
When I run this code... the page is displayed... I click on the edit button... the row changes to edit mode and I CLICK the checkbox (can see a it checked).Then click on "Update" Button... which takes me to GridView1_RowUpdating event. If I check the status of the "box"... it's checked status is ALWAYS false Why?

I am trying to access the current 'active' top level node from a sitemap repeater from outside of the ASP.NET repeater used to render it, this is for CSS styling purposes as I want to place the child nodes on the subsequent row with different styling horizontally. At present I have the following code which I can't get to display correctly using CSS.
[code]....
I would like to display the child nodes on the next light blue element which I can do perfectly well from a seperate div if this was not rendered using a child repeater. In the image below Blog and Services are top level nodes and their subseqent nodes (2 for each) should be displayed on the light-blue row below. Is this possible?
here my code-
<asp:TemplateField HeaderText="HIGH RISK (10-12)" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblHighrisk" runat="server" Text='<%# Eval("URANGE").ToString().Split('-')[0] %>' />
</ItemTemplate>
</asp:TemplateField>
but that is giving compile time error 'Server tag is not well formed'
