View 1 RepliesI have a FormView in InsertItem that contains one DropDownList linked to a Table Datasource to display ItemCodes. In that "lookup" table I also have a Retail and Cost field.When the user selects the item from the drop down, how can I have these to field carry over into my new record that is being inserted. The new record also has a Retail and Cost field that are TextBoxes.Basically I am populating the new fields with the default values from the DropDownList.
View 1 RepliesI'm working on adding a new webapp to an existing website. I've been directed to write the webapp in ASP.NET. The existing website is written in ColdFusion. For the most part, the ASP.NET webapp is completely stand-alone, but it needs to interact with the ColdFusion code in one important way - if somebody logs in to the ColdFusion site, we don't want them to have to log in again when visiting an ASP.NET page.
When someone logs in to the ColdFusion site, their username is stored in a cookie, along with a login token that can be looked up in our database. My .NET is a little rusty, so I'm having trouble visualizing how the ASP.NET code should use this data. I've already written a simple MembershipProvider that can be used to log in/out out the ASP.NET app using the data in our existing database tables, which are shared with the ColdFusion code.
What I'd like to know is - how can I make sure the ASP.NET app detects the cookies set by the ColdFusion app (I imagine they'd be sent to the ASP.NET pages, since everything is hosted on one domain), and automatically logs the user in using the MembershipProvider and Forms Authentication, using the credentials supplied in the cookie? I'm thinking that putting some kind of cookie check and log in function in the Global.asax file, set to run every page load for every page... but that seems kind of clunky. Also, do people still use the Global.asax file anyway? I had thought there was a more modern method.... Also, how can I manually log someone in using Forms Authentication and a custom membership provider? Currently my code allows the user to log in using the provided login control, but I'm not sure how to log the user in without them having to do anything.Looking over the MembershipProvider tutorials and the MSDN documentation it seems to me like the answer should be staring me in the face, but for some reason I just can't see it. Maybe not enough coffee....
I have been using a querystring to carry over the value of a DDL to the next page. Now I want to carry over values of two Drop down lists through Querystring on to my next page.Here is my code to carry over one DDL using QueryString:

Response.Redirect(String.Format("Option1_result.aspx?ddl1={0}", DropDownList1.SelectedValue))
End Sub

View 3 RepliesJust wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

Now how i add the clik event to image control and open the image in New window any Idea?
I'm not even sure if this is the correct approach for this -
I have a DB that stores information, as well as a location to where images are stored
ie ProductImage = ~/ProductImages/BulkRetail.JPG
I'm using a repeater to list all the products, which works fine for all the labels I use but not for the image location. I'm using something like this, but it doesn't work:
<asp:Image runat="server" ImageAlign="Left" ImageUrl='<%# Eval("ProductImage") %>' />

I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

1.Should I be able to just open the Image handler and see the image...if so then I think my problem is in it because all I see is a blank screen.
2. Is image/png a legitimate image type? The file is a .png file but I have found no information that this is a image type.
3. Not sure I have the IMAGEURL coded correctly.
I have hardcoded my variables in the image handler just to test.

I am using Microsoft's MVC design pattern and I have a method in my controller, which sets the data source of a gridview. Whilst I can bind all the other values in the gridview, I am stuck setting 4 hyperlinks. The hyperlinks need to work in the explanation given in the link below: [URL]for forcing downloads to keep the location of where files are saved to private, which I want set in the controller.
To fully explain what I am doing, in my controller for the gridview, I am setting the gridview's data source using ICollection, which is an object containing results from a query. From this collection, I extract a value which has the name of a folder which contains a number files. So, what I have done is to cast my collection to a object, to get folder name and then use a foreach loop to get each folder name. Then to get the files inside each folder, I use Directory.GetFiles, which returns a string array - I wrote string[] files = Directory.GetFiles(ConfigurationManager.appsettings["filepath"]+folderName); . I have set 4 properties for each Hyperlink I want to set.
It is at this point where I am stuck, because even though I can get to the files, I am unable to set the Hyperlinks to these files. Each time I try an set the NavigateUrl property, I get the error message Object not set to an instance of an object. Plus, I have two other issues to resolve:1) Even though there are 4 hyperlinks, not every hyperlink will be set. In other words, if there are only two files in the folder, I only want to set the appropriate hyperlinks. So, how can I iterate through the string array, and get each value inside the array to do a check?2) When I set my Hyperlinks in my controller, how do I simply pass the file and keep the file's actual storage location hidden as given in the link [URL]
I have successfully rewritten URL but not able to get background images which are defined in stylesheet.css file. Im using master page. i have used this <link href="<%=ResolveUrl("~/StyleSheet.css") %>" rel="stylesheet" type="text/css" />but the background image defined in css class file not rendering on page.Images are defined in .css file are as follows -> background-image: url(image/img_276.jpg);
