I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.
There are some objects contained in each of those objects... for instance there is an Address object.
object.Address.Line1;
object.Address.Line2;
When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:
"A field or property with the name 'xxx.xxxx' was not found on the selected data source."

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.
These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:
(in case of updating textbox.text):
[code]....
However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.
I got this code from a working windows version of the software, now I'm rewriting the code of the windows to make it web based. How can I access the values of the gridview?
I have a custom object and a generic collection of this object.When databinding, how can you get a reference to the object's collection similar to how DataRow.Table works? I understand I may need to write code to handle this but I'm not sure where to start.I considered adding a property to my custom object class to store the collection in, but would this generate too much overhead setting this for every object in the collection?
I've been pulling my hair out over this one... I've searched on the net and even in the forums, but can't seem to come up with an answer for a simple question.I tried the following code inside my html to get the selected value that comes from our database into the grid and it doesn't work. I am positive that a value exists for the itemType. It is 1. Instead of Checked, I tried SelectedItem and SelectedIndex. Neither of those worked.
I erased the above code from my grid and inside the ItemDataBound event, I placed the following code, but don't know what other code I should place next after it. I know the value inside "itemType" is 1 by debugging it.
<code> RadioButtonList itmtype = e.Item.FindControl("rblItemType") as RadioButtonList; </code>
How can I simply find the selecteditem in the list coming back from the database inside the itemdatabound event?

i have an objectdatasource bound to the System.Web.Security.Roles getAllRoles methods, this method returns an string[] with the names of the roles, then i wanna bind a gridview with this datasource, but it shows me just a one column named length(the length of each role name), how can i instead the length of the string that represent the role name, put the role name?
This is my first attempt at paging on a listview. The first time my page loads it loads the listview fine, but when I try to use the paging I get the following error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Here's my code:
[code].....
When I take the following line out I don't get the error, but i need it to populate my controls:
I got 2 listboxes in a window form, one on left and one on right. The 1st listbox have some items while the 2nd listbox is empty. Also there are 2 buttons between the 2 listboxes which used to move item from/to the 1st and 2nd listbox.My problem here is that after I bind the data to the 1st listbox (from a dataTable, using DisplayMember and ValueMember) , and I try to move 1 of the item from this 1st listbox to the 2nd listbox and I want that the selected item is also removed from the 1st listbox by:
But the selected item is not removed from the 1st listbox.Also on deselect button when i move item from 2nd listbox to 1st listbox,it displays error message "Items collection cannot be modified when the DataSource property is set."

I'm using the following code to search through the controls collection in a version 3.5 page:
CheckBox cbTest = new CheckBox(); RadioButtonList rblTest = new RadioButtonList(); String sID = ""; String sType = "";
[Code]....
The problem are none of the TextBox, Checkbox and other controls show up. There are over 50 controls on the page and only 5 show up and they are either Generic, Literal or HTMLHead controls. I've tried in both the load and button click procedures with no luck.
I placed one FormView and one GridView conrtrols on the same page with one linqdatasource that is connected to both controls via their DataSourceID properties. While the GridView works without any problem (on updating) the FormView doesn't update the record.I traced the FormView events and found that in FormView1_ItemUpdating the argument e.NewVaues.Count = 0 as well as e.OldVaues. Count (also zero). Getting items from e.NewValues[index] or [key] causes an obvious exception. However, all the bound contolsn this wa
I am binding a datalist to some table 0 of a dataset from the database. When I check the number of rows in the dataset table 0 it's coming as 129 but when I check the count of the datalist items(using Datalist_Name.Items.Count) inside the datalist item created event I am getting a maximum count of 128.Due, to this I am unable to assign values to the last label control(last as in the last row) present inside the datalist dynamically. I am not sure where I am going wrong. I even tried to replicate the same code inside the ItemDataBound event but even then I am getting the same error.
The code on one of my aspx pages is giving me this error:
I'm getting this on the code behind for export to excel on one of my pages.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).It is referring to this line Me.GridView1.Parent.Controls.Add(frm)
I have this code in the aspx page. I am using two gridviews. I need to have this on the page any way I can fix the code so I can use that export to excel you created?
