Forms Data Controls :: Displaying Data In GridView?
Oct 22, 2010
I'm trying to display soma data in a gridview. This is my table below:
ID Book Rating
1 MAGIC IN THE OUTFIELD 5
2 ONE GIANT LEAP 2
3 SPIDERS na
4 RULES
5 NO TALKING 1
6 NO TALKING
7 MAGIC IN THE OUTFIELD 3
8 SPIDERS 4
9 NO TALKING na
10 ONE GIANT LEAP 3
What I need to display in the gridview is this:
Book Average Rating
MAGIC IN THE OUTFIELD 4
ONE GIANT LEAP 2.5
SPIDERS 0
RULES 0
NO TALKING 1
The problem is the database that I'm working with, as you can see some fields in the Rating column are empty or 'na'. How can I calulate the Average for each book.

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.

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:

Here is my DataSource Code

Is it within the SELECT statement of the DataSource where I can need to configure using "Country" not "CountryID"or "Status" not "StatusID"?

As of today my gridview is no longer showing when I run it in my browser. I have made changes to the database recently but the code behind and aspx file remains the same. No errors are coming up. Just the gridview is now blank and it was working perfectly shortly before.
<asp:GridView ID="grdFixtures" runat="server" AutoGenerateColumns="False"
DataSourceID="FixturesDataSource" OnRowCommand="PushMatchID"
DataKeyNames="MatchID">
<Columns>
<asp:ButtonField ButtonType=Button CommandName=StartMatch HeaderText="Match Scoring" Text="Start" />

On one of my pages I display a Gridview. This contains a list of questions generated by a SQLDataSource, with a dropdownlist on each row containing the answers for that question. The answer values can be different depending on the question, so I populate them in the RowDataBound event for the gridview, using question information.
As the list of questions is longer than the page I have placed the gridview within a Div which allows me to use scrollbars to navigate the gridview. I also use some methods to preserve the location of the last question answered - so that on answering a question, the gridview does not reset to show the first part of the gridview.
This works fine for IE7, which is what I have been using for the development, and which part of my customer base uses. However, the other part of my customer base uses IE6, which causes a problem.
When an IE6 user attempts to answer some questions, they run into issues. Should they scroll down the gridview, when they select a value from a dropdownlist (Effectively, when they answer a question), there is a postback and all of the visible (i.e. onscreen) dropdownlists appear to be cleared. However, on mousing over any of the dropdownlists, their value is then shown. On using either the scrollbar, or on using the mousewheel to scroll the gridview, all the dropdownlists are 'refreshed' and their values are shown.
At no point does the application appear to lose the data, it is just not showing it until there is a mouseover or the gridview is refreshed. Another odd aspect of this is that this does not apply to the first 5 rows of the Gridview. Any of these can be altered without there being this display issue. Should the gridview be scrolled enough to show some of the first 5 rows and some subsequent rows, only the subsequent rows will have this display issue.
I have tried various things to correct this - originally I called my retrievescrollposition method on the SelectedIndexChanged event of the dropdownlist, but have since moved it to Page_Load as the Else branch of if (!IsPostBack). I tried rebinding the DropDownlist in the SelectedIndexChanged event, but this only helped with the Question I was answering - the display of any other onscreen questions was still affected.

I want to insert a record in the gridview and i have designed it as the fig: below shows.
Initially there is no data in the datatable to which the gridview is bound to,so the gridview is not displayed when the page load,ok
I want to ask that is it possible to display Gridview on page load with only the header and the footer?
i.e;the user can see the header names and the textbox and drop down list at the foorter so that they can insert data in the grid?

Grid View I added a function and then called it in the following event.
private void ShowNoResultFound(DataTable source, GridView gv)
{
source.Rows.Add(source.NewRow());
gv.DataSource = source;
gv.DataBind();
int columnsCount = gv.Columns.Count;
gv.Rows[0].Cells.Clear();
gv.Rows[0].Cells.Add(new TableCell());
gv.Rows[0].Cells[0].ColumnSpan = columnsCount;
gv.Rows[0].Cells[0].Text = "No Data Found";
}
protected void AppList_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.AffectedRows == 0 )
{
ShowNoResultFound(AppList, GridView1);
}
}
It displays the following error The type or namespace name 'DataTable' could not be found (are you missing a using directive or an assembly reference?
ListView
Added the following. It shows the message but not the header. Also tried adding ShowHeader="True". It it not allowing it.
...
<EmptyDataTemplate>
Sorry, no data to display.
</EmptyDataTemplate>
</asp:ListView>
