Forms Data Controls :: Databound Event Is Triggered While There Is No Data In The Listview?
Jan 13, 2010I have 2 pages (let's say one is a.aspx and the other one is b.aspx). In the b.aspx, there is a nested listview control (let's say outer listview and inner listview).Therefore, there is an event on databound for the outer listview. so basically, the event will programmatically bind the datasource for the inner listview.
Now, in a.aspx there is a button to open a new window (with unique window name) b.aspx. The very first time click on the button, a.aspx opens a new window for b.aspx without triggering the databound event. However, the second click and so on will trigger the databound event which is causing an error because there is no data yet in the outer listview.My question is, what could have possibly triggered the databound event while there is no data in the listview?

View 1 RepliesForms Data Controls :: Cannot Fire An Event And Databound Controls?
Jul 14, 2010While writing a web application Using MS Web Developer 2010 Express, I noticed a rather disconcerting behavior of the asp:DropDownlist control.When using databinding and you assign a DataValueField the selectedIndexChanged does not fire or change unless the value of the DataValueField changes no matter what the value of the DataTextField. This means that if I have several different text values(States/Provinces) with the same datavalue (US/Canada) I cannot fire an event if the text changes (the textchanged does not fire either) as long as the datavalue doesn't change (all States are US all Provinces are CA). This would seem to be a counter intuitive behavior?

Forms Data Controls :: Databound Checkbox List, Default Values And SelectedIndexChanged Event
Jul 12, 2010i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --

in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.

Forms Data Controls :: Item Databound Event Thowing Security In Medum Trust Webserver?
Jun 28, 2010last year I inherited a webapplication that seems to refuse to run on a new hosting company's servers due to a "security violation"... Our old host was bought out and now sucks...So I uploaded the code to the new company - looking forward to some sleep and found that my life was about to get more complex.. I go the good old generic security error
System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object
The biggest issue was that it didn't say where the error was.. Digging deeper (taking the code appart one block a time) the error was being triggered by the followin itemdatabound event. My host says it is because they are running under medium trust, but I am not seeing why this block should cause issues. Any help very much appreciated.

Forms Data Controls :: Gridview Save Existing Data When Adding Rows Via Arraylist?
Jan 19, 2010I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.

Dim Counter As Integer

For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))

Forms Data Controls :: DataBound GridView Checkbox Field Not Updating SQL?
Jan 14, 2011So I am uding a GridView bound to a SQL data source.
I have a template feild bound to a SQL BIT
<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.
Forms Data Controls :: Several Data Formatting In Dynamic Databound GridView?
Jul 31, 2010I am facing certain problems with the data formatting in GridView when the data is bound dynamically to it.
I have a DateTime column and want to only show Date from it and not the time.
Another Decimal type column which accepts decimal upto 4 places, I want to show decimal upto the places defined in the particular value (don't know how to put it in the correct way, but here is an example of what I want).
i.e.
1.0000 should be displayed as 1 after the databound in the gridview.
Similarly,
2.3400 --> 2.34
1.0050 --> 1.005
1.1000 --> 1.1
