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 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.
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) [code]...
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:
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 trying to create a bound column and bind the data with the below piece of code . And the column has two files Name and Fee but the code binds only the Fees column and Name column become empty..

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 am having a hard time updating from my gridview based the value that I am setting in the datakeynames it is the Ucc field I keep getting and index out of range exception on the e.keys[0]. I have done this before so I am confused what I am missing here.
what it is i have a datagrid bound to a datatable.This datatable fills from a sql table. This datatable will have 2 columns which is 'part' and 'description'.What it is I want to have a couple of chk boxes next to the datagrid which will filter it by column 'part'.The issue is the datagrid will have about 1000 records so i dont want to do a for next loop searching for field part for a certain filter
DLRepository is a class with method getDLandRules. I am binding the gridview with the list that is returned by method. Now I would like to iterate through the list and add 1 more column to each row that is returned. currently, I am getting an error

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.
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:
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?

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.
I'm hitting a wall trying to format a boundfield of a gridview. I've tried suggestion about setting the htmlencode to false, but that didn't make a difference.The column I am trying to format is:<asp:BoundField DataField="FromDate" HeaderText="Start Date" DataFormatString="{0:MM/dd/yyyy}" HtmlEncode="False" />
