I have a gridview control that has a different background color for alternating rows (done using cssclasses). In the RowDataBound event code, I want to change the background color of a ListBox control in one of the cells to match the row color. I have tried the following (in blue), but it does not seem to work. The listbox control still remains with white background. How may I determine the background color of the row so that I may set the ListBox background to match?

A corollary question is, "How may I programmatically reference an item within a CssClass?" For instance the CssClass is named "datagrid." How do I programatically retrieve the value of "background-color" that is defined in this CssClass?

I want to get the gridview row back color in the rowdatabound event,
I tried as follows
if (e.Row.BackColor.Name.ToString() == "Red")
{
}
but always i'm not getting any value in the e.Row.BackColor..
Is it possible to loop through a gridview and based on if a checkbox is checked, then change the backcolor to that current row? I have gave a few attempts, but luck.

I have an ASP.net page with two textboxes where the user types in input. I applied a requiredfieldvalidator to both textboxes as well. However, I also want the textboxes to change to a backcolor of red if the form is invalid when the user clicks the button to submit the input. I tried this code below in tthe button click event, but doesnt work...
If Page.IsValid = False Then
txtCosts.BackColor = Drawing.Color.Red
txtRevenue.BackColor = Drawing.Color.Red
End If
How else can I change the Backcolor of the textboxes when the input is invalid.......

View 6 RepliesI have a strange problem on my website that affects both IE 7 and IE 8 browsers, in that on a form with textboxes, once the cursor is placed in an active / enabled text box, the cursor itself shows up like 2 or 3 pixels to the left of the textbox. Mind you not a show stopper, but it is weird, because when you type text into these, the cursor flashing still appears before the last letter type. I think users will find that a bit confusing if they notice it.
I've verified that this is not happing in Firefox, Safari or Chrome.Any thoughts or ideas how to fix this?I tried padding the text box to move the cursor over, which worked but didn't fix it from showing up before the last letter typed.

How to prevent browser from caching image, Trsponse.Cache.NoStore didn't work
I have a gridview set up as follows:
[Code]....
Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..
I want to get the gridview row back color in the rowdatabound event.

I have created an iframe which contains the label, "powered by MyWebsite.site" The "iframe itself" accepts arguments, so other webmasters may customize the appearance of it.
The problem is that since the background of the iframe could be customized, anyone can "vanish" the "powered by MyWebsite.site".
So what option do i have? How should i dynamically change the label color depending on any background?

The validation load in this page worked on the first click of btnDonation, if I don't change anything and click the btnDonation again, it automatically go to my confirm page. Instead, I want it to continue to check for requiredFieldsOK(). Note that if I fill in one of the missing required fields, the validation will work.
My question is: How can I continue to check for requiredFieldsOK() even if user didn't fill out any additional information?
Why the error does not appear at the UI layer? I am using ExecuteScaler

Precondition: There's a web application that leverages ASP.NET security model. There's also an Active Directory (AD) integration component. It provides AD users and roles as if those are application's own users and roles. The relations like "is in role" between AD user and AD role are stored in AD domain, of course, but are cached by the web application.
Problem: Let's say AD user1 is a member of AD role1. When web application starts, it caches this relation. Now if the AD administrator removes user1 from role1 using AD console, the application doesn't know about this change - the cache entry is kept. This becomes a security hole because the role1 might have permissions the user1 should no longer have.
There are two сcontrary opinions how to solve this:
"Listen" to AD changes and trigger cache entry removal once the operation is detected on AD server - because we are responsible for correct AD component functioning Leave the cache untouched - because we didn't put the entry there and should not remove it either
