View 1 RepliesDataSource Controls :: Variable Connection String Parameter In A DataSource Control
May 20, 2010I 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="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ 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, 2010I 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" />
DataSource Controls :: Sqldatasource Insert Method - Copy Data To The Other Datasource By Selecting Checkbox
Feb 25, 2010i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.

DataSource Controls :: SQL Datasource Commands Not Working On Hosted Pages?
Dec 1, 2010 im explaining this base on a test page that i have hosted as i was trying to track down my problem, i have a hosted page which i have hosted on the internet on a hosting service provider. the page has a normal gridview that is linked to a SqlDataSource. and theSqlDataSource has sql statements for selecting data, updating and deleting. They all work fine locally and even if i host them locally through IIS. but on the hosting service they down work. only the select work, which means i can view my data on the gridview but i cant manipulate it, delete and updating dont wanna work, they dont do anything. and the worse part is that im not even getting an error from them, on the grid i have enabled the autogenerate edit button and the delete, how can i make the update and delete work, or what is it that makes them not to work. the code for my test page is below

Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?
Sep 29, 2010Scenario:
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, 2010I 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.

DataSource Controls :: From Datasource After GridviewSelected?
Feb 8, 2010I have a Linq datasource attached to a gridview. The gridview only shows a subset of the data in the datasource. When the gridview SelectedIndexChanged event fires, I need to access the entire selected data object in the datasource. I can get it from the linqdatasouce_selected event by this:
[Code]....
Problem is, this event fires when the page loads, not just when the gridview selection is changed. So how can I access this from gridview events where e isn't equal to LinqDataSourceEventArgs like it is in the datasource event handler.
