Forms Data Controls :: Bind A Collection Within A Collection To A Gridview?

Jul 26, 2010

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."

Add Controls To A Collection And Update From Collection?

Mar 25, 2011

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.

Does The Request.Cookies Collection Get Copied To The Response.Cookies Collection

Apr 1, 2011

I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?

Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.

Forms Data Controls :: Reference To An Object's Collection?

Jan 31, 2011

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?

Forms Data Controls :: Trying To Find SelectedItem In Collection?

Apr 13, 2010

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.

<code>
Checked='<%# DataBinder.Eval(Container.DataItem, "itemType")%>'
</code>

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?

Forms Data Controls :: Items Collection Cannot Be Modified When The DataSource Property Is Set?

Feb 17, 2010

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:

lbMembers2.Items. Add(lbMembers1. Text);
lbMembers1.Items. Remove(lbMembers 1.Text);

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."

Forms Data Controls :: Number Of DataListItem Objects In The Collection Being Fetched Incorrectly?

Jul 1, 2010

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.
