ADO.NET :: Displaying A Range Of Data In Detailsview?
Nov 29, 2010
I am persevering with visual developer express 2010 whilst learning visual basic from hello world stage onward. In the meantime I have a difficulty . I am trying to display a range of data in details view which is being fed a parameter from a dropdown list. I cannot seem to come up with a query that will pull over all data from a column that is less than a certain number and then display it with distinct values in the dropdown. for example I would like say to pull over height data where it displays all data below 20m all data below 30m etc. is this possible without heavy coding?

Vista Sp2/VWD 2008 Express
Structure:
Simple List/Details combination of aspx pages.
Issue: Data not displaying in DetailsView web form control. (Details view control doesn't display at all although it's Visible and Enabled properties are set to True.) Other things such as textbox and hyperlinks do display on the page.
I'm feeding a QueryString from a user defined(hyperlink) column in a DataGrid located on the parent(list) aspx page.
The DetailsView aspx page has an object data source pointing to a table adapter that has a query defined that is expecting a parameter of type INT. The parameter source is coming from Request.Querystring. As noted above, the DetailsView control is not displaying when the page is loaded. I've alternately fed the ID from Request.QueryString to display in a textbox on the page; the ID parameter is present and displaying in the text box.
IF the ID Integer needed by the DetailsView's ObjectDataSource is making it to the page and if the ObjectDataSource is working(I can test preview data) I'm wondering why the Details view is not displaying, and displaying with data.

How can I display edit and new buttons without duplication in a detailsview control? This is a question from a past exam paper for 70-562. Part of the question is below:
"The company CIO assigns a task to you. According to his requirement, you must make sure that the users can insert and update content in the DetailsView1 control. Besides this, you have to prevent duplication of the link button controls for the Edit and New operations. At line 3, which code segment
should be inserted?"

I have a dropdownlist bound to a table and the selection filters the detailsview. After a new record is inserted using the detailsview, the new record is displayed in the detailsview and the initial record is displayed in the dropdownlist. After the insert, how can I get the dropdownlist to display the new record?

I have a Range Validator as follows. It is for restricting values between 1900 and 2070. However, it fires error when I enter a alphabet also. I want this to be fired only if the user enters integer values. How do I overcome it?
<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtYear"
ValidationGroup="report" ErrorMessage="EM1|Year" MaximumValue="2079" MinimumValue="1900"
SetFocusOnError="True" Display="Dynamic" Type="Integer">
<img src="../../Images/error.gif" alt="Format" />
</asp:RangeValidator>

When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

I need to create a report that will show the list of data that is within that range of period. The scenario will be:
- the user will choose the starting month and the ending month from a drop down list. (for example, starting month = July and ending month = September)
- then the report will be showing all the data within that range of month chosen by the user. (data from July until September will be shown, including data from the month of AUGUST)
- the problem I'm having is that when I choose the starting month and ending month as shown above, I only get the data from the month of JULY and the month of SEPTEMBER, the data from month of AUGUST will not be shown.

I recently had to remove a field from my datakey on all three gridview tables. On the top level table the field (ignum) remains as a non key field. On the two lower level tables it was removed completely. Now, the top level gridview opens correctly, but when I click on select this should bring up all the records in the second gridview associated with the selected row in the first gridview, but I get the following error:
[Code]....
I've looked at everything I can thing of and everything looks ok. The tables look good, I've removed all references to the removed field and I've restructured all the code to account for the changes. I'm missing something, but I don't know what. I've gone through debug step by step and the error occurs as I leave the GridView1_SelectedIndexChanged code. It goes down to the End Sub line with no errors, but when I step again it errors out. Here is that section of code.

I have a ListView InsertItemTemplate where there is field (Date) using the AJAX Library CalendarExtender. I want to add some validation to this field, whereby they can't add a date that is later than today. So I have added a RangeValidator and tried to set its MaximumValue to DateTime.Now on Page Load. Unfortuantely it isn't working.
