Right now I'm working on a mockup of the actual application so I'm using a mock DataSet with only 20 records. Problem is when I try to sort gridView by clicking on a column it's VERY SLOW. It take...

For a new project, we are evaluating the use of ASP.NET MVC and one of the requirements is that we have a very rich UI experience with inline record editing (i.e. the user clicks "edit" and the labels turn into text boxes and drop down lists and can update, delete, or cancel). We need all of the drop down lists to be populated from a da...
I am creating a dropdown list in code for a gridview. I want to create an addhandler so I can have access to the selectedvalue. However, here (Rowdatabound) the add handler does not get fired off. How should I go about this? Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEven...
Hi Use the DataKeyNames property to specify the field or fields that represent the primary key of the data source. You must set the DataKeyNames property in order for the automatic update and delete features of the GridView control to work. a) According to above quote Update should only be possible if DataKeyNames is set, and yet I...
hi 1) If you are using ConflictOptions.OverwriteChanges, then you also need to set GridView.DataKeyNames, else GridView won’t pass these parameters to the SqlDataSource and thus the Delete operation won’t succeed. But if you’re using ConflictOptions.CompareAllValues, then DataKeyNames doesn’t have to be set. Why? 2) But why nee...
I have an ASP.NET 3.5 GridView on a WebForm. The GridView gets data from an ObjectDataSource which is set via the DataSourceID property in the code in front.

It's easy enough to grab the data from the DB with a SP passing in the start date and number of months etc, but I need to group the information by month when it is displayed in the page. e.g. ...
I realise there is a solution for this but I am struggling to get it to convert to VB correctly :( I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.

1) When SqlParameter.IsNullable is set to true, received null value is converted to DBNull.Value and sent to database. Thus I would assume setting IsNullable to true only makes sense when GridView’s Parameter.ConvertEmptyStringToNull is also set to true? 2) Both GridView’s and ObjectDataSource’s parameters have a ConvertEmptyStringToNul...

If these two types of option...
