I'm looking to replace the hardcoded IE with something like

Web Forms :: Deal With NULL Values With Regex Validator?
Jun 26, 2010I have some fields in my db that have a value of "NULL". These are displayed in the Data controls as "NULL". When I try to commit an update the Regex validator is catching this and not allowing the update because it doesn't match the pattern of the regex.
I've thought of one way of solving this, which is to add the value "NULL" to the pattern for the regex. I'm curious though if there is a better way to solve this issue.
Forms Data Controls :: Passing Repeater Container.dataitem To JavaScript Function?
Sep 16, 2010I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?

Forms Data Controls :: Gridview Non-visible Values Always Go To Null?
Jun 24, 2010Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?

C# - Container.DataItem Being Passed As A String Literal?

Forms Data Controls :: When Updating Gridview When Hide Columns Values Turn To Null?
Mar 5, 2010I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

Dec 6, 2010I have setup my business object to have a create_date and edit_date members both datetime datatypes.
