I have this grid view
[Code]....
The first page show up just fine, when i try to go to the second page of the GV i get this errorThe GridView 'GVCreditMemos' fired event PageIndexChanging which wasn't handled.
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
View 3 Replieshow can I specify DataKeyNames for a GridView when using a dictionary as DataSource?
[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
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 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 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.
View 2 RepliesI 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 am using gridview to display some columns with autogenerate column as 'true' and not added boundfields,headers.
And i am used stored preocedure for data source in gridview and i used dataset for gridview databind.
The gridview columns comes dynamically for each time.
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" />
View 1 RepliesI have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))
I have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.
I am having trouble with displaying double data in gridview bound coulumn. I want it to display as it is... But it gets rounded off when displayed.
Like my 1.34 displays 1.00
1.57 - 2.00
and so on. But i want it to display as it is i mean with decimal points, without rounding it off.
to format Amount in 00,00,000.00 in Bound Field of gridview?
View 8 RepliesI have a gridView, with two DataKeyNames: MemberID, and CommitCustomerID.
One DataList has this sql statement:
SELECT * FROM [tblMemberProfile] WHERE MemberID = @MemberID
It pops up perfectly fine.
I also have another DataList with this statement:
SELECT * FROM [Incidents] WHERE CustomerID = @CommitCustomerID
I know this sql command works I have tested it with my data.
However I dont think the DataList is getting the proper value for the selected row in this DataLists case.
How can I make sure when I select the row in the GridView the proper parameters are going to the proper DataList sql statements?
I have a webpage with many updatepanels. Each panel contains databound controls including gridviews (GV). They are bound at runtime so the number of gridview columns varies with each bind. the controls are bound only once in Page_Load event ( within if (!Page.IsPostBack) )I added a linkbutton to each header in the GV in the RowDataBound event. Once the header is clicked, the event is handled in the OnRowCommand and it calls a method to bind the controls with new data.Things work fine if the GV is bound with every postback (no if (!Page.IsPostBack) condition) but I don't want to bind all the controls with every postbackMy problem is that the OnRowCommand is not fired if the GV is not bound on the postbackI even tried to add click handler for the linkbutton but that didn't work either.
View 4 RepliesI 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)?
Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

I have a gridview in aspx page bound to a stored procedure, and data is loaded from the database. I have 2 problems which I am banging my head against. 1. Stored Proc has default values of NULL ( which is a DateTime db type) and I don't get how to give them as default values and once I have valid date time ( from textbox on form) , I need stored proc to take this value . ( I have done this from server side code but if this is able to acheive from client side that would be great.
2. As shown below my gird view is present ( no columns are bound and since the data is loading from server side ) I am unable to do sorting on the gridview without a sort expression. Does any one know how to do this?? This is my biggest concern. I have checekd all the articles I could find on google
