Forms Data Controls :: Hyperlinkfield In Gridview Works In All Cases Except One When Using Datanavigateurlformatstring

Feb 12, 2011

I have a gridview with a hyperlinkfield inside of it. There is a dropdownlist that re-databinds the gridview onselectedindexchanged. I'm using the datanavigateurlformatstring attribute of the hyperlinkfield to make the url, and in in most cases it works as it should. HOWEVER, when one particular item is selected from the dropdownlist the associated links that are supposed to be created in the hyperlinkfield do not work. They arent actually clickable. In the source they have no href (which is what the datanavigateurlformatstring is supposed to set along with datanavigateurlfields). I have debugged to see that before and after databinding the information going into the control is correct, but still it doesnt work. In every other case it works.

Forms Data Controls :: Datanavigateurlformatstring - Passing Multiple Query Strings?

Jul 12, 2010

I am using the datanavigateurlformatstring within a datagrid property with the property set something like;


Unfortunately, when the new webpage opens, the url contains lots of spaces and I'm struggling to remove all of the spaces. The code actually works but looks a bit messy, see below.

"http://localhost:34354/website1/editrecords2.aspx?rid=2&sid=2& dip=5 & iid=3 &tid=3"

but should look like this

"http://localhost:34354/website1/editrecords2.aspx?rid=2&sid=2&dip=5& iid=3&tid=3"

Forms Data Controls :: How To Add Columns To A GridView Programatically

Jun 23, 2010

I need to create a grid where the users can see all the memberships, and have a line of checkboxes for each existing role, and be able to check/uncheck roles to allow access authority.

I managed to build a datatable that adds columns and displays them properly, but I have not been able to programatically add columns to the grid based on whatever roles are stored in the system.

I can display the users and their roles by just specifying AutoGenerateColumns="true" when I do that, the checkboxes are grayed out, and the users do not want to have to click a button to open them up.

Here is what I can't figure out.

How do I programatically add columns to the GridView? I have some code in Pageload, but it doesn't work, so it is commented out?How do I turn on all the rows for the entire GridView to edit mode? How do I access the column name for the role they just checked so that I know what to add with the ystem.Web.Security.Roles.AddUserToRole(UserName, Role)?

Forms Data Controls :: Add ListItem Programatically With On Item Selected?

Jan 22, 2011

I have a DropDownList on my aspx page and wanted to add ListItem programatically. The item will start from 2 years ago to 1 year later (e.g. from 2009 to 2012) so if the year change, it will be automatic. I also want the current year to be selected by default.
In the code behind, I did this:

For i As Integer = (DateTime.Now.Year - 3) To (DateTime.Now.Year + 1)
DropDownList1.SelectedItem.Text = DateTime.Now.Year

As result, I'm having the items in this order: 2011 (selected), 2009, 2010, 2011, 2012. The 2011 is duplicated (I wonder why). When I view the source page on Internet Explorer, I have this:

<option selected="selected" value="2011">2011</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>
