I want to add ComboBox type control in GridView, how is it possible just like that?
You add an enum control to the grid control (not GridView). Also adding a string field with relation to a table (a foreign key) will give a lookup which is similar to combobox.
A good starting point is reading about form controls.

I have an asp.net gridview with several rows/pages.
There are some fields below it which display full details of the row which has been clicked on gridview.
I then change a field value on the details below area and the new data is saved programmatically to database.
However the value on the gridview just changed below, doesn't change.
I would like to just change de cell value on the gridview programmatically so there is no need to reload the data grid.
I am basically looking for something like:
GridView1Row.row(currentrow).column(5)="xxxx"
I've search around and found some solutions based on _onrowdatabound but this is not correct, as I just want to change one cell of the grid.
Any ideas ?
The easiest way would be to change the value in your datasource and then binding the datasource to the grid again. (don't reload it from the database just change the value in the datasource)
Which control should I use to show post records from my database in ASP.NET?
On my project page I would like to show recently featured projects. The number of projects can vary. I'm looking for a control like GridView or something that alter the properties of accordingly to get data from my database.
Below is an image of what I would like my page to look like:
I have been told to use asp:ListView but I don't know how to use it. Is this the right solution for my problem?
You could use a GridView Class
Displays the values of a data source in a table where each column
represents a field and each row represents a record. The GridView
control enables you to select, sort, and edit these items.
Or a Repeater Class
A data-bound list control that allows custom layout by repeating a
specified template for each item displayed in the list.
I have changed the DefaultMode property of my details view to Insert since I wanted to create default insert form for my sql server table. Now I wish to add the validators, like RequiredFieldValidator,RegularExpressionValidator etc.
So is that possible? If not, then is there a shortcut way to create an Insert form for a database table in Asp.net like SQLFORM in python framework web2py(refer here)?
Convert all boundfields to TemplateField, open EditItemTemplate of each TemplateField to add validation controls.
I am confused about something really simple in ASP.NET. I have seen many times a pattern where there is a three column table, with label, control and validator in each column, which I can put together pretty straightforwardly. However, what I don't understand is how to handle binding here. If I have a table with Customer record and FirstName, LastName and PhoneNum, I want a page that takes customerId in the query string, and binds that record to the page so that I can use Bind() as the text box values.
However, there is no DataSource property on the page to bind the record to. I know I am missing something obvious, but I can't figure it out.
Any help would be appreciated.
You need to put your controls (labels, textboxes, validators) inside a control that accepts data binding (ie. FormView, GridView, Repeater, etc.etc.) and then bind your data to that control.
One way to do this is to use a DataSource Control such as a SqlDataSource and use it in conjunction with a Data Control that will bind to the previous datasource control like a DetailsView. Then you configure your DataSource control to only bring in data for the particular CustomerId; the SqlDataSource allows you to use a QueryStringParameter as part of the select statement to the database.
Each of the above controls have wizards that will allow you to easily configure them.
ASP.NET newbie here. I would like to create a form with multiple types of controls for inserting a single record into a database table. This record has a "Type" field which is a foreign key, and I would like to populate a combobox with the possible values for it. I tried drag'n'dropping the table in design view (like in windows forms), but it always generates a gridview. How can I make it generate a form where I can specify the types of controls?
Thanks in advance
you could check detailsview and formview control.

Sounds like you either want to use a DetailsView or a FormView control.
