C# - Getting DataBinder Item's Max Value?

Mar 30, 2010

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.

C# - Binding To A List <string> Using DataBinder.Eval?

Sep 3, 2010

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?

Web Forms :: Redirecting A User Selected Item In A Drop Down List To Another Item?

Feb 10, 2010

I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?

If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.

MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

Forms Data Controls :: Check If Item Exists In E.item.dataitem?

Oct 27, 2010

I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:

if(e.Item.DataItem.Contains("MerkID"))

{
//Code for linq query 1

} [code]...

So of course the if selection doesnt work, but how can i do that? I already tryed this:

DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))

But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...

Forms Data Controls :: Repeater Add Before Every 1st Item, Adding After Every 2nd Item?

Oct 6, 2010

I have a repeater control:

<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>

Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>

So output would be (not including table tags generated by repeater control):

<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>

How would I do this in the ItemDataBound event of repeater control?

C# - Select Item In Formview Based On Drop Down Selected Item

Jul 4, 2010

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.

I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.

I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
