We can find the certain control(dropdownlist) in the Edit Template and adjust its properties.

This demo is a continuation of my previous example “Binding Grid View with Data”. When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. Text; bit when ichange it to string id =((Text Box) Grid View1. Line 136: Source Error: Line 134: string Um = ((Text Box)Grid View1. The ONLY available method was the custom binding expression. However, you're encountering some problem on set the dropdownlist's databinding property , correct?How can I get the 'Binding for Selected Value' options enabled? OR, what would be the Custom binding expression I should use to make it work. Based on the aspx control template you provided, I think it is a quite typical case of inner control databinding and in the VS IDE's design-time interface, you should be able to edit the databinding field(Selected Value property) of the dropdownlist interactively...Durante la edición se desplegara al usuario un cuadro de texto en donde podrá cambiar el nombre, pero los países estarán definidos en una lista desplegable desde la cual serán seleccionados. Mediante la propiedad Auto Generate Edit Button se indica que en la grilla estén definidos las opciones de edición, por lo tanto habrá ciertos eventos que será necesario agregar en el código.Es muy importante tener en cuenta que la carga de la información de la grilla solo se realice una vez al inicio de la pagina.Anyway, here is a simple Gridview's template I used in my local test project(which uses the North Wind database's Products/Categories tables): ===================================== ' statement.

In addition, for customization on databinding of the nested controls in Grid View, you can also consider using the Grid View's "Row Data Bound" event.

In my previous blog we discussed how to bind a Template Field containing Drop Down List using a lookup table.

Binding was done at design time using the Data Source ID property of C1Grid View. Now, in this blog, we discuss how to bind a Template Field at runtime.

En el ejemplo se explicara como cambiar el control de edición por defecto, o sea un Text Box, que se desplegaría al usuario, por otro especialmente definido para la selección por medio de un ítem concreto, por medio de un Drop Down List.

- La definición de un identificador para cada registro de la grilla, sin necesidad de desplegar este al usuario.

Es por eso que el evento Load de la pagina define la carga de los datos de la grilla dentro del bloque Is Post Back, le cual tiene que estar negado, ya que solo durante la carga inicial del formulario será requerida esta operación.
