Displaying GridView When No Data Exists?
Mar 3, 2010
I am using a sqldatasource for filling one GridView and on page loading or before taking any action, there is no data (default value=null) and normally the datagrid is empty (using emptydatatext="no records found etc etc...").. Issue is I can not see the header of that grid in empty case, but only the emptydatatext!
I have tried to use some code of the references below, but no success, because I'm not using DataTable control as a DataSource, but directly filling the gridview from sqldatasource! useless references:
[URL]
P.S. I'm not usign DataTable as a DataSource, but sqldatasource (from the Data Controls), and I want to show header, when sqldatasource is null or empty ?!

I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.

I would like to check if a particular value already exist in the database Gidview row. If the value already exist, tell the user that he has already entered the record and don't save. otherwise save the record. In my case I want to check the "Random number".
<asp:TextBox ID="txtRandomNumber" runat="server"></asp:TextBox>
Maybe it could be done with a foreach loop statement.

I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........

I have created a web service and successfully displayed the data in a TextBox within another Project.
However, I have modified my web service so the data returned will return multiple enteries for the data rather than a singular value.
I would like to display all output fields from my web service into a GridView.
Is it possible to do this without modifying my GridView to display a ListView output etc...
Basically, I just want to place each field into a Gridview.

is there a possibility to do the following:
I have a GridView which has a button in each row. On click event I want to open a new window displaying the xml data of the row.
I tried to this with the following code in the RowCommand - event:
var doc = new XmlDocument();
doc.LoadXml(content);
Response.ContentType = "text/xml";
Response.ContentEncoding = System.Text.Encoding.UTF8;
doc.Save(context.Response.Output);
This always generates a script error:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.

I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
Date1 ProjectCode1 Hours ApproveChkBox
Date1 ProjectCode2 Hours ApproveChkBox
Date1 ProjectCode3 Hours ApproveChkBox
Date2 ProjectCode1 Hours ApproveChkBox
...
I would like to be able to display the information like:
[code]....
Is there anyway to do this using a nested gridview? Or is there a proper way to display this type of format?

In one of my application, I have around 2000 records which i am displaying in gridview with normal paging.
Now I want to change this paging facility and would like to show a "more" button at the footer(just like [URL] has). The moment user clicks it, the next set of data will be retreived. This will go on till all the records are fetched.

I'm using the following code to retrieve the contents of a folder and display the info in a GridView - all good.
[Code]....
This works fine, but it returns ALL available data about the files, and I'd ideally like only a few of the columns. I'd also then like to be able to order the columns.

I'm having a bit of trouble with Paging within a GridView grid I have set up. I have added the paging but whenever I click on the next page or the last page buttons, the page refreshes and displays blank (i.e. no gridview but my regular search parameters are displayed.
I was trying to search for a solution throughout the web and came across someone that looked to have the same issue. He moved all of his queries into the Page Load method, and the paging seemed to work. I cannot do this because I have 2 different buttons: Search and My Order, both of which perform different queries based on if a date has been selected or what the search is on (Order Number, License Number, Description, Status, etc).
My paging method looks as follows:
[Code]....
From what I can tell this is an issue with no longer having the data set when making the paging call. Is there anythign that I can do?

Im displaying a Gridview full of data but the column "Country" is displaying the CountryID and I want it to display the Country 'Name'", same with State/Prov and a Status column I have. I've looked around at BoundField Properties and such and can't seem to find where I can configure this. Is it straight within my DataSource? Here's my code:
