DataSource Controls :: How To Display A Group Of Events When The Value Is 12/19/2010

Dec 19, 2010

I've written this code to display a group of events when the value is 12/19/2010. This means each day I need to change the "default value" to the current date to display the events of the day. I would like to make this such that the change occurs automatically, that is, on 12/20/2010, I'd like to see just the events for 12/20/2010.

<asp:SqlDataSource ID="testeventdate" runat="server" ConnectionString="<%$ ConnectionStrings:testdateConnectionString %>" SelectCommand="SELECT [eventDate], [eventDesc] FROM [programEvents] WHERE ([eventDate] = @eventDate)">
<SelectParameters>
<asp:querystringparameter DefaultValue="12/19/2010" Name="eventDate" QueryStringField="eventDate" Type="DateTime" />
</SelectParameters>
</asp:SqlDataSource>

DataSource Controls :: Recurring Events - Database Setup?

Mar 9, 2010

I would like to create a webform in asp.net that allows you add events to a overall application, anyone then can go search that event by a specific date and if that event falls under that recurrence day you will see it. This would be similar to Outlook where you can say it recurs every Monday, Tuesday, Wednesday,... or every third Monday, ...Specifc day of the month, etc. I have created the webform but now I have the problem of how the database works. I have been reading for the past couple days about this but I cannot figure this out. I found some posts that say you can create a seperate table aside from your main table that holds the eventid and the dates of the recurrenecs. The problem is this table could amount to thousands of lines from just a few events input. My question is, is there a formula out there that can do this without creating a crazy big recurrence table? .... If not, how many lines can a MS SQL database hold before it has performance problems?

Here's a link to another forum I found with my same question but I do not understand the answer:

DataSource Controls :: Variable Connection String Parameter In A DataSource Control

May 20, 2010

I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:

<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%&#36; ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%&#36; ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>

As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

DataSource Controls :: Access Property Of Object As Session Variable As Declarative Datasource Parameter Value

Oct 27, 2010

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:

[Code]....

However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?

Sep 29, 2010

Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.

My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.

Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.

DataSource Controls :: Error Handling At Datasource Level

Jun 19, 2010

I have a website which displays news information. It displays the titles at the default (home) page and when click it shows the full story.

I use object datasource to load the news titles.

Now, sometimes the database server lose its connection or changes to the database and it affects the whole website because error is reported at the Application level. I would like the Home page to still show but the section where the news titles usually appears will now show an error message that the database is down (Refer below my part of my code).

How can I achieve that?? I tried to do that at the page_error level but it displays nothing. I don't want to pass the error to application level, I want to handle at datasource load/binding level so that it display this error message at the news section and other home website information can still be shown.

Forms Data Controls :: Datacontrol Pass From Masterpage To Child Page?

Jan 3, 2011

I have a masterpage and 1 childpage. In master page there is a listbox to present a data when a child page button is clicked. Listbox name is x1 for example.

When i am in childpage's button click event: i do not see that x1 named listbox due to namespace i guess.

For example masterpage name is masterpage1. When we are in childpage in button click event.

To try masterpage1 objecttemp = new masterpage1()

button1_Click() (child pages button click event)

masterpage.x1.items.add("button 1 clicked"); it is not being able to reachable too.

Also i encountered another issue related to that. When in masterpage for example masterpages click event. (its a login panel and when user clicks login, i had wanted to add a text information to listbox). In child pages when user clicks to login button which belongs masterpage top panel. It does not seem like working. It may be related to asp page master child life cycle and i do not know good. I wanted to able to add a string to listbox that belongs and come from masterpage in child page. Is there any way to use a datacontrol in childpage that belongs to masterpage.

Do I need to do some hand coding? If so, where should I put it?

I'd also like to add some text items to the listbox so I could say populate the listbox with a query, plus an "other" option, so that if "other" is selected, a textbox will appear that will let the user specify a new item.
