I have a Calendar control on a webform and add a GridView to one of the cells. I am trying to get a reference to the GridView on a button click event, but just can't figure out how..

I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

And the code behind:

I have a gridview that has 20 columns in it. 3 of them are date fields. I am using templatefields but not edittemplates, only itemtemplates because the users want to update multiple rows and then update the data all at once. I have a panel with an update panel and a calendar on it and in the grid I have a popup extendar added to the textbox in the cell to make the calendar show but I can't get the value from the popup calendar back to the cell. Does anybody have an example or is there a better way to do this?

Is there a calendar control that i can use in a web page that will allow my organisation to share the diary?
View 1 RepliesI have a calendar control that will have events displayed within each cell.
I want to use a pre formatted gridview and simply bind the gridview with a dataset dynamically and display it within the cell of the specified day.
Is there a way to do that or do I have to dynamically build a gridview for every day that there is an event?
So here is the template gridview and datasource:
<asp:SqlDataSource ID="sqlcalitemtemp" runat="server"
I have created a form where the user selects a date from an asp.net calendar control. I would like it default to 12/25/2010 if no date is selected, partially to prevent a stack overflow.
This is the code of the calendar control
<InsertItemTemplate>
<asp:calendar id="Calendar1" runat="server" SelectedDate='<%# Bind("startDate") %>'>
</asp:calendar>
</InsertItemTemplate>
And this is what I added to the insert parameter. I've tried all different versions of the date including adding a time component but no joy.
<asp:parameter Name="startDate" Type="DateTime" DefaultValue="12/25/2010" />
This is the error:
SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

View 1 RepliesIn a .Net 2.0 project, I have a Calendar control within a GridView that has a method set for its OnSelectionChanged event. However, the event never fires and I don't understand why. Here's what's in my aspx page:
[Code]....
I am using C# ASP .NET 2.0. On my web form I have a GridView and a Calendar control and I want to do the following:
With the Calendar control, I only want to show the current month, and links for the previous month and next month. Not the actual days of the month.
I want the days in the Calendar control to populate my left-most column of my GridView. For example, if March was the current month then I should see 31 rows in my GridView starting with 03/01/2010 in the first row and 03/31/2010 in the last row.
When you click the previous month or next month link I need the GridView to change for the selected month.
Is it possible to use the ajax calendar extender with the listview control specifically within the edit tags . .Net is not throwing any errors but the extender is not working.

So the asp:calendar control... I am able to place linkbuttons on the calendar to a specific date just fine. I'm a little lost on how to have the linkbutton stretch across multiple days. Vehicle is scheduled and now admins that use the app would like to see on a calendar the requests shown from start date to end date. Here is where I'm at.

The information should start on Jan 6 and end on Jan10.
I have simple SQL DB with invoice informations (i.e. invoice date, client info etc.). I'd like to use 'selecteddates' from the Calendar control to show the invoice information in a gridview with the invoice dates which are in the 'selecteddates' group.
View 1 RepliesI've got a detailsview control on a page. The table that it interacts with has a DateTime column in it. This column is nullable, and a lot of the records have null for that value. In the EditItemTemplate I've got a calendar control. When I try to put the DetailsView into edit mode, I get the following error message:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.

I am convinced that the problem is the null values in the DateTime column of the table. I've done some web searches on this, and some have suggested placing some dummy values into that column, but that seems more like a kludge, rather than a solution. How do I keep nulls in the table, and yet not have that preceeding error come up when a user tries to edit the selected record?
I want to change the text of the user name text box which is inside a log in view on selected index chaged event of a drop down list.

View 5 RepliesI was having issues with a gridview and CSS so I posted my question here and received a wonderful answer which lead me to implementing CSS Friendly Adapters for all of my gridviews.I have a table nested in the EditItemTemplate that holds the textbox and the button for a calendar control where I want them, it inherits the CSS applied from the CSS Friendly Adapters. I don't want it to change the CSS so I have changed the CSS inline, with no success. More importantly...
I also have a Ajax calendarExtender control to change the date for that field. When the popup is displayed the table in which the calendar is shown in also inherits the CSS Friendly Adapters code. I have tried fixing this by creating a external css sheet for the calendarExtender's cssClass property and a blending of CSS occurs where the items not specified by the Friendly Adapter Code are set correctly by the calendar.css file that I created.Is there anything that I can do to force the tables inside of the gridview to ignore the inherited Friendly Adapter Code?
