View 1 RepliesI've a page in ASP.NET, whose appearance can change based upon a given parameter(say query string),
How can I achieve this in ASP.NET, Master pages concept won't work here, as even the contents of the page and positioning of the controls on the page can change based upon the parameter.
One solution I can think of is using XSLT, but is there any other solution I can use to solve this problem? Is there any concept of templates I can use here?

i want to import profile image from my facebook contact list and after retrieve image i want to show it a gridview.
View 1 RepliesFor this I am using ASP.NET 4.5, C#, and Entity Framework to SQL.
I have some sections of my site where users can make multiple entries and can optionally upload attachments. There is a page where the user can see a gridview that acts as an overview of the entires. I have been asked to display a column with a paperclip icon if an attachment exists.
The way the database is structured, the table that holds the entries has columns like this:
id, schoolName, dateStarted, dateEnded, attachmentId
The attachments are in another table. For this table the attachmentId will hold an Int32 or be NULL (no attachment). My current query looks like basically like this:Â
var query = context.applications.Where(c => c.id == applicationPrimaryKey);
var results = result.educationUniversities.ToList();
gdvEducationUniversity.DataSource = results;
gdvEducationUniversity.DataBind();
Â
Gridview looks like this:
Â
<asp:GridView
ID="gdvWorkMentor"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="id"
<Columns>
[Code]....
I somehow need to create a condition where an image of a paperclip is shown if the attachmentId value is not Null. Optionally I imagine the query could be re-written to return a true/false value based on if the attachmentId value is null though I'm not certain how to do this.

View 1 RepliesI'm no expert with Image controls, or dynamically adding anything, but I seem to have some problem when dynamically adding image controls
When the page loads the images are "there", but they don't actually show an image...just an image "box" I guess you could call it. It's not the "broken" image or "invalid" image display, but a friendlier one that doesn't make sense to me why it's there.
I look at the page's source and literally everything's fine, but I'm not sure what's going wrong. I can show you my code, and hopefully someone will point out the dumb thing I'm doing wrong:

So, it takes all the .JPG files in the folder "Pictures" of my project's folder and creates an Image control to be put into Panel1 with the ImageURL as its filename (with Directory Path) and even set the ID to its filename (so no duplicate IDs). Again, the source is exactly how it should be, but no image is shown.
Me with C# asp.net. In my sqlserver database table I have 2 fields Id and Imagepath like
Id Imagepath
1 images/car1.jpg
1 images/car2.jpg
1 images/car3.jpg
2 images/car4.jpg
2 images/car5.jpg
On page1.aspx I have a text box and a button, on entering 1 in textbox and on button click load, I want to show page2.aspx and all the images with Id 1 (ie car1.jpg,car2.jpg,car3.jpg) should be shown. How can I show like this with out placing image control by default in page2.aspx because number of image varies ie if I enter 2 I want to show only 2 images.
As apart of my learning, I want to learn more about the data controls in asp.net.I have used the gridview in situations where it is specifically bound to an sql data source and handles updates and deletes really easily, but I have thought of something that I want to model, however am not sure which control is best to use.
The situation I have thought about is a bank statement. Most bank statements have the transaction name/details in one column, then two columns for debit and credit and then a third column for a running balance.I have read about using a footer row for insertion records, but I imagine you would not have the same about of columns in a footer (insertion) row. I.e. A transaction would not have a debit and a credit entry field, only an entry field for the amount and a dropdown for debit/credit.
Would the gridview be the best control to model this situation on? Or is there another control that would be best used? The control won't be talking to a sql datasource, but probably a datatable in the codebehind.
I have a menu control that I'm binding with database data, and I want to use a Popout image for submenus, but the image won't show up. I've tried using the default image and using a custom image and neither of them shows up. I've also tried turning it on through code and that doesn't seem to work either. Also, for certain menu items, I would like to show a padlock indicating that security is implemented for this link, but I can't seem to get that to work either. I've tried something like this:
mnuChildItem.PopOutImageUrl = "../images/Icons/menu_out.gif"
I am working with telerik controls, to display gridview data. However, I would like to know how to checkthe following values before displaying
1. If the date is after 1 month (since entry ) and if referal is true. Then display the template column below
2. If referal has been done, then dont display value

View 2 RepliesI'm having trouble retrieving the value of a cell in a gridview.
I think it may have something to do with the item template calling a function since I am able to retrieve the values of cells that are not calling a function in the same gridview.
How can i extract the displayed value from this cell?
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
lblTest.Text=row.Cells[7].Text;
}
<ItemTemplate>
<%# GetWednesday(decimal.Parse(Eval("Wed").ToString())).ToString("N2") %>
