If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I would like the rows of my GridView to have strikethrough based on a bound data value called IsObsolete. I tried to do this:
<RowStyle BackColor="#EFF3FB" Font-Strikeout='<%# Bind('IsObsolete') %>' />
But obviously this doesn't parse. I'd rather not do this in GridView.DataBound().

I have a gridview control on a .aspx page. It is a bound control. So basically I didn't have to write any code to pull the data from database and show it on the grid.
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionStrdatabase %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT * FROM order WHERE SETTLEMENT_DT > AS_OF_DT"
</asp:SqlDataSource>
<asp:GridView ID="GridViewMissingCusipNumbers" runat="server"
AllowPaging="True" AllowSorting="True" SkinID="Professional" Font-Name="Verdana"
Font-Size="10pt" Cellpadding="4"
HeaderStyle-BackColor="#444444"
HeaderStyle-ForeColor="White"
AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" DataKeyNames="BO_SECID"
onrowcommand="GridViewMissingCusipNumbers_RowCommand" Height="285px"
onrowediting="GridViewMissingCusipNumbers_RowEditing"
onrowupdated="GridViewMissingCusipNumbers_RowUpdated"
onrowupdating="GridViewMissingCusipNumbers_RowUpdating" Width="426px"
onrowcancelingedit="GridViewMissingCusipNumbers_RowCancelingEdit">
<Columns>
<asp:BoundField ReadOnly="true" DataField="BO_SECID" HeaderText="BO SECID"
SortExpression="BO_SECID" />
<asp:BoundField DataField="CUSIP" HeaderText="PROXY CUSIP" SortExpression="CUSIP" />
<asp:BoundField DataField="PRICE" HeaderText="PRICE" SortExpression="PRICE" />
<asp:CommandField ShowEditButton="true" />
</Columns>
<HeaderStyle BackColor="#444444" ForeColor="White"></HeaderStyle>
<AlternatingRowStyle BackColor="Silver" BorderColor="Black" />
</asp:GridView>
So far so good. But where is no data is not returned from the database, I want to display something on the page saying "No data returned". But I don't know which gridview control event gets fired so that I can write some code in it to check if the records returned are zero.

I'm trying to add a row grouping row to my data-bound gridview. It works fine on the first response, but at the postback i got the "Failed to load viewstate" error.There is the code for the GridView's RowDataBound event:
Private Sub AddGroupingRow(ByRef eRow As GridViewRow, ByVal Css As String, ByVal ColSpan As Integer, ByVal Txt As String)
Dim cell As New TableCell()
cell.ColumnSpan = ColSpan
cell.CssClass = "Spacing FieldCell"
cell.Text = Txt
Dim row As New GridViewRow(-1, -1, DataControlRowType.DataRow, DataControlRowState.Normal)
row.CssClass = Css
row.Cells.Add(cell)

I have a query expression which I am binding to a GridView in Page_Load. The data I want to capture in the SelectedIndexChaned event is in a BoundField defined thus:
<asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True"
SortExpression="ID" Visible="False" />
If I set Visible="True", I have no trouble getting this data. Is there a way to hide the ID field and still get the data?

I have a foreign key (TeamID) in a GridView. I use a TemplateField to display it as the lookup value (TeamName) in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access the TeamID. I can get the TeamName from the label. I tried putting the TeamID in DataKeyNames, but that fouled up my dropdown when saving (it reverts to the original value). So, how can I get the TeamID?

I am looking for a method to format gridview bound data using javascript.
I know you can have custom formating in Eval using:
[Code]....
But I am looking for a way to perform this task on client side, rather than doing it on the server.
For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].
So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?

I have a gridview being data bound by an objectdatasource which points to a BLL/DAL. I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield. This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it.But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order. E.g. I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order. If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed.

I have a GridView control that has one column of checkboxes set up like this:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="RowCheckBox" runat="server" Enabled="false" Checked='<%# (bool)DataBinder.Eval(Container.DataItem ,"Associated") %>'/>
</ItemTemplate>
</asp:TemplateField>
Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.
The problem I'm having is that when I try to read the value of the checkbox from the codebehind:
CheckBox checkBox = (CheckBox) row.FindControl("RowCheckBox");
bool checked = checkBox.Checked;
If the value bound to it was true then checked is still true, no matter if it was toggled or not.
Edit: Corrected a spelling mistake. Question still stands though...

I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?

VS2010 Ultimate ASP.NET 4.0 Web Appliction project
I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.
There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

I have a gridView which is populated with the code below. This is working perfectly except for one issue. In the "Region" column, I need for each region name to be a hyperlink. If I set the row code to dr(0) = "<a href='table_display.aspx?IO_ID=" & objDataReader("IO_ID") & "'>" & objDataReader("Region") & "</a>" it actually displays the entire string of text from "<a href..." through "</a>", but not as a hyperlink. I have read in many places to manually put a hyperlink field in the aspx page, but I would really prefer to do this programmatically in the code-behind.
