Vb.net - Nested ASP.Net Controls Not Defined?

Aug 18, 2010

I have a couple of controls that are set to runat="server", but are showing up as "not declared" in the vb code behind. They are not being setup in the designer.vb file at all, even if the design.vb is re-created. The only thing that I can think might be causing this is that the controls are inside of a custom control. The code looks something like this (it has been modified because of NDA):

Forms Data Controls :: Looking For Clean Approach To Building Nested Datalist Or Nested Gridview

Jun 17, 2010

Is there a better, cleaner way to do this in ASP.NET 2.0?

An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.

The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.

The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

Forms Data Controls :: Trying To Create A Nested Gridview, But I'm Stuck At The Editing/deleting Part Of The Nested Gridview?

Mar 1, 2011

I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

Forms Data Controls :: Set MultiView ActiveViewIndex In Nested GridView2 Using Nested GridView2?

Objective:

Have the MultiView1 display only if Frieght values exceed 15.50. If check box is checked, retreive the row values of the Gridview1 and Gridview2 to perform a task.There will be two check boxes. One will be conditionally hidden. Each check box has a different function.

Example: Send an email notifying this entry has been flagged. I am using Visual Studio 2005 with ASP.NET 2 due to availability of resource. I have checked out numerous sites without finding the specific answer.

Data Controls :: Hide Child Nested GridView In Multilevel Nested GridView If No Data Or Empty

Dec 5, 2013

In Nested Grid, we get a '+' sign.   The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.

C# - Proper Implementation Of Nested API Calls Using Connection Pool And Nested Transactions?

Jan 4, 2010

I need to know the best way to do the following. I have nested business level APIs (say level 1 & level 2). L1 needs to call L2. Both APIs use the database layer directly at their own nesting levels.

Now, in the database layer, I fetch the db connection from the pool each time as follows:

SqlConnection conn = new SqlConnection(connString);
conn.Open();

Is it proper to fetch the db connection each time on every DB level call as above? I know it will return a connection from the ASP.NET connection pool. However, wouldn't it be better to maintain the same DB connection throughout the nested calls (or throughout the current http request lifetime)? Will fetching a connection from the pool each time cause issues with nested TransactionScopes?

Forms Data Controls :: Find Value Between Two Defined Values?

Dec 15, 2010

I have a database that tells me what contract is in effect on specific streets but between mile marker values.

For example, Main Street is 10 miles long. Contract ABC123 applies to miles 0 - 4.9, and contract 999555 applies to miles 5-10.

My user will enter the street name and mile value into textboxes, and the results will be displayed in a gridview.

Getting the Street name portion of the query is working fine, it is this mile value that is confusing me.

In my table I have StreetName for the name of the street, and for the mile range of the street the table has BegMile (beginning value) and EndMile (ending value).

How do I get the correct answer back when my user is entering a value between BegMile and EndMile?

Page Instantiation Faster If All Controls Are In The Markup Vs Defined In Oninit In Codebehind?

Jun 2, 2010

I was having a discussion with a co worker about some controls I implemented. He objected to my use of dynamicly instantiating controls in the code behind, because it will be slower than specifying the control in the markup. I thought he was talking about output cacheing which to my understanding only caches the rendered output of a page not the instantiated Page object. He said no its a different type of caching. Unfortunately he was unable to give me any documentation to backup the claim so I am wondering if anyone here has ever hear of any such type of caching, and if so is there any documentation on it that I can refer to.
