aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB.In this article I will show you that how you can validate the controls which are inside the Grid View control.

From the following chapters you can see some important operations in ASP.

For this I will make the editable Grid View and use the Required Field Validator for the Text Boxes.

I will also show you that how you can use validation against the Drop Down List control which is contained inside the Grid View control.

Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.

One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").

Sql Client; public partial class _Default : System.

Open() Dim cmd As New Sql Command("Select * from stores", con) Dim da As New Sql Data Adapter(cmd) Dim ds As New Data Set() da.

I've a sample below, the Grid View Template is bound to Category Name.

On Row Updating is fired when the 'Edit' button is clicked. Is the data bound to the gridview, your gridview markup doesn't say that it is bound to Category Name.

You can find the textbox that is generated on edit event in the Row Updating event below and assign it to a string variable.

Then have a seperate function to update the values entered and finally call your Bind Grid() function which again binds the gridview..

The "Description" and "Choose" columns are template columns.
