How can I get a DataItem in a listView in the ItemEditing event?? I thought it would work similar to a repeater but I am at a loss. I need it to do something like this:
protected void lvUsers_ItemEditing(object sender, ListViewEditEventArgs e)
{
var item = lvUsers.Items[e.NewEditIndex];
[code]...
i am new in ListView Control. I have a List view to show shopping products. in each data Item i put a link-button for "Add to cart" button. in my scenario clicking on this button causes ShoppingCart.Instance.AddItem("Product GUID") to call. how can i perform that?
i set CommandName="Select" in Link Button and performed this:

So I've got two listviews; one nested inside the other. The parent is being bound to a collection of objects that contain fields such as MaxPrice, MinPrice, and SuggestedProducts. The nested one is being bound to the SuggestedProducts collection of the parent item. How could I reference MaxPrice and MinPrice in the nested listview? Is it even possible? If you need any clarification, leave me a comment and I'll update my question.
View 4 RepliesI use this bit of code in the code behind a OnRowDataBound comand of a gridview:
Code:
(int)DataBinder.Eval(e.Row.DataItem, "SectorID")I have made some changes to my Class so that SectorID is now a list of ints. How do i return the first item in the list using the above method?
I'm using DataTable for DataBinding.
Can I access dataitem (I think its suppose to be DataRow in my case) from aspx?
Something like:
<img alt="" src='<%= DataItem("ColumnName") %>' />
I am accessing a DetailsView from the following event
public void dvDetails_DataBound(Object sender, EventArgs e)
I am casting the sender to my detailsview like so
DetailsView dv = (DetailsView)sender;
Now when I look in "dv" I can see the DataItem property has the data I want in it under a field name, but I dont know how to write the code access the value??
The field name is shown in the dataitem property as "_DTMON_F", I tried to say
Datetime myDate=dv.DataItem["_DTMON_F"]
BUT C# doesnt like the syntax
I have some code like this:
<div><%# DataBinder.Eval(Container.DataItem, "M_ClassProperty") %></div>
<img src='<%# DataBinder.Eval(Container.DataItem, "M_AnotherClassProperty").To<string>() %>'
but there is no component which wraps this code like Repeater, DataList or something like that. How can set the set a DataItem to this code to show the values of an object of a class.
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 RepliesAfter postback (click on a button) in my ASP.NET form, all the DataItem of my form are null. Why? What should I do to retrieve the content of the DataList even after postback?
protected void buttonAddRecord_Click(object sender, EventArgs e)

foreach (DataListItem item in listFields.Items)

<%# ((DataRowView)Container.DataItem)["SomeProperty"] %>
<%# DataBinder.Eval(Container.DataItem, "SomeProperty")%>
From Google i figured out these can be used to bind the columns in GridView to ArrayList. But what is "some property" ?For example i have a ArrayList in .aspx.cs as
static ArrayList componentSelectionArray = new ArrayList();
so can i just write in grid view to bind a arraylist to grid view columns as:
<asp:GridView ID= "GridView1" runat="server" AutoGenerateColumns="true">
<Columns>
<asp:TemplateField HeaderText="ComponentName">

I have a repeater control bound to a collection of objects. When I fire off the button_onclick event, I need to have access to the dataitem to get the object properties. Here is what I have and my question is how do I access the underlying objects in a repeater in a button_onclick event

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've bound a IeNumerable<class> to a repeater.On the repeater i've got a ItemDataBound.Right there i want the value of 1 of the items in my string s.So i've build this code.But if i run it i get this error:
System.Web.HttpException: DataBinding: 'dftv.AutoDiskClass+Merk' does not contain a property with the name 'nMerkID'.
if i run it again and put a breakpoint at this row, and push the DataItem, i get this information.
But how can i get the value of nMerkID in my string?The class i put in it is:
public class Merk
{
public string nMerkID = "";
public string Merknaam = "";
}
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?
I'm trying to populate the DataPager using Container.DataItem (I'm not allowed to use FindControl) but I get this error

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>
<% }%>
When handling the OnUpdateCommand event on a RadGrid the DataItem is null.
I thought that this would also represent the data item being represented by the row.
The Radgrid is populated from an IList and in the handler the code looks like this...
protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e)
{
if (e.Item is GridDataItem)
{
var gridDataItem = e.Item as GridDataItem;
var client= gridDataItem .DataItem as Client;
This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.
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'
I have a button inside my <ItemTemplate> in GridView and I want to call a javascript function on the OnClientClick of that button passing the DataItem value as a parameter of the javascript function
[code]....
If I will not put a parameter in CreateEditAddess() this works well but I need the parameter.
I know I can put the OnClientClick event value in OnRowDataBound event of the gridview but I don't want to put it in CodeBehind. It seems like the server tag is not parsed correctly.
I have a problem that is really confusing me.. I'm trying get get info from a database and populate the relevant labels. I've got it working on one page, but not on another. The only difference is that the one that works is in a repeater.

I am NOT formatting at DECLARATIVE time
The following code works perfectly
[Code]....
Can I directly format e.RowDataItem.
I don't want to format by using e.Row.Cells[4].Text
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?
Using an objectdatasource I would like to pass an entire DataItem to a function, within a databinding statement. I have found a way that works, but I don't like the look of it. ;-)
Lets say I have a class called "People", with two properties "firstName" and "lastName". I have an objectdatasource which returns a list of "People", and I use that to populate a Repeater.
I also have a function called "GetFullName", which takes a "People" object as it's parameter, and returns the lastname and firstname with a comma between them.
In the ItemTemplate of the repeater, I could do this:
<%# GetFullName(CType(Container, RepeaterItem).DataItem) %>
-but it looks like such a hack. (Doesn't it..? Maybe it's just 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 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?
