I want to know how to populate Excel multiple sheets using htmltextwriter from dataset based on condition
Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:

I need to auto fit the dropdown width to auto fit with the cell in excel using c#.net.

I am currently using Visual Web Developer and have a website with 2 pages which are "Tables.aspx" and Variables.aspx". I was wondering if their is a way to make a specific cell in a gridview clickable/as a hyperlink so that it would take the user to another page and display the required information in another gridview based on what Table Name from the gridview has been clicked on?
The gridview on the "Tables.aspx" page has 5 fields and they are Table ID, Table Name, Table Description, Source and Record Count. The field that I want to make as a hyperlink is the Table Name field and when clicked upon I would like all the relevant information (Table Name, Variable Name, Variable Description) for this field to appear in a gridview in the "Variables.aspx" page. The database table names that would be required are "variables" and "tables". In order to do this would I have to create/run some sort of SELECT command in behind the source tab for the gridview?
NB table name comes from tables database table and variable name and variable description comes from the variables database table.
the scenario is like: had a gridview that consists of template field in which hyperlink is present...now one of the gridview's column is id ...whn i clk on the hyperlink a pop-window has to open along by passing the id value of each corresponding row.. now wat i have done is ...inside a foreach loop,i looped for each gridview item and i created a hyperlink and assigned that via findcontrol....now in the navigateurl of hyperlink i had given as...
hyperlink.navigateurl="javascript:void(window.open(sample.aspx.....
in the above line how to pass the parrameter as query string ,,,had found several threads where the querystring is passed as normal parameter,,,but not inside a javascript..

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
