Forms Data Controls :: Stop Databinding When There Is An Error In The Select Method?
May 23, 2010
I have a dropdownlist (drpClients) bound to an object datasource (odsProgramClients). In the dropdown's databound event, I load a dynamic table based on the selected item in the dropdownlist. This all works well. However, if I force a problem in odsProgramClients select method, it continues to the databound event of the dropdown and attempts to load the table, even though dropdownlists underlying select method failed. I wish to stop the databound event from firing if there is a problem in the select method. I have code that traps the error in odsProgramClients select method.
[Code]....
[Code]....
How do I stop the dropdownlist from databinding, if there is an error in it's underlying datasource?

I am using an ObjectDataSource control to call a MapInfo object. This object has two properties:
public IList Visits
public int TotalAvailable
The select method returns an IList but the TotalAvailable property is also populated. I have set the TypeName in the ObjectDataSource to the MapInfo object but because the Select method only returns the IList I don't have access to the TotalAvailable.
[code]....
Is there any way to access this value. I know it is being populated in the MapInfo object but all that gets returned from the Select method is the IList

protected void Button19_Click(object sender, EventArgs e)
{
SqlDataSource conn = new SqlDataSource();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Database2ConnectionString1"].ToString();
conn.SelectCommandType = SqlDataSourceCommandType.Text;
conn.SelectCommand = "SELECT FROM table1 (a, b)VALUES(@a,@b)";
conn.SelectParameters.Add("a",TextBox1.Text);
conn.SelectParameters.Add("b", TextBox2.Text);
int rowsAffected = 0;
try
{
rowsAffected = conn.Selectt();
}
catch (Exception)
{
Label1.Text = "Error";
}
finally {
conn = null;
}
if (rowsAffected != 0)
{
Label1.Text = "Data saved";
}
}
well it returns error no overloading method for select (P.S. same code work fine for insert)

I am having dataset and I want to validate particular column for Integer(Numeric) value.
e.g.
ErrorRows = dt.Select("LEN(Year) <> 4 ")
Above I have to validate Year column for Numeric value otherwise it should give me erroneous records which have data other than numeric.

I have extended GridView in order to have consistent look & feel, paging and sorting. However, when the page is first time loaded, the select method is getting called twice. It works fine when i move between pages in pagination.
Note, i am using Asp.net 2.0.

The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "

I'm a beginner at this, sorry if I get the terminology wrong. I'm using Visual Web Developer 2010 Express with C# 2008 and .NET v4.0 to create a website which will have a database application.
I have a SQL Server table which contains some bit fields (FruitsEarlySpring etc). When I linked this to a GridView with SELECT only defined, the bit fields were displaying as greyed-out checkboxes. To replace these with something more attractive I used Item Templates with Labels instead of the Checkboxes with custom binding e.g. Tick(Eval("FruitsEarlySpring")) and this logic in the code-behind file:
[Code]....
The label text font family is set to Webdings so that the "a" displays as a tick (a 'check'?), and this works very well.
My problem is, I have a separate page which displays the same fields using a FormView and I want to display them the same way, referring to the same logic, but I can't seem to access the method. I get runtime error CS0120, "An object reference is required for the non-static field, method, or property 'APR2.Fungi.Tick(object)'
line Line 338: <asp:Label ID="EarSprLab" runat="server" Font-Names="Webdings"
Line 339: Text='<%# APR2.Fungi.Tick(Eval("FruitsEarlySpring")) %>'></asp:Label>
Before this I tried not qualifiying the method name and got error message CS0103, "The name 'Tick' does not exist in the current context". The code-behind files occupy the same namespace, and the class and method are now both public so I don't think it's a scope problem. I have searched this forum for similar problems and no, I don't have two master pages, or a duplicate set of files.

I will declarate a attribute, but it gives me an error
This query works fine and returns 1 record from type int:
SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
And when I will declarate a attribute/parameter it gives me an error:
DECLARE @dataObjectVersionId INT
SET @dataObjectVersionId = SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
Error message:
Msg 156, Level 15, State 1, Line 2

I have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.
One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.

I've created a templated user control by following the example on the microsoft support pages. I won't post it all but the important part of the CS file looks as follows:
[Code]....
I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:
[Code]....
Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).

I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:
text='<%#Bind("Question") %>'
At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).
