The DataGrid RequiredFieldValidator control is used to verify whether a value is entered in an input box, and the RegularExpressionValidator control is used for regular expressions. See other information for instructions on regular expressions.
Where the ControlToValidate property is the ID number of the text box that needs to be validated. The text in the label is the prompt displayed when the checksum is unsuccessful, and the display property is the way of displaying the message.
The contents of the <Columns> tags in the DataGrid are the columns of the DataGrid, and the columns can also be added to the template column, which corresponds to each template column and can have <itemtemplate>,<edititemtemplate >,<HeaderTemplate>,<FooterTemplate> a few tags, where <ItemTemplate> is the DataGrid in the normal display when the column of the label,< Edittemplate> is also the style of the DataGrid column in the editing state.
In these tags we can insert the control and then use Datagrid1.item[i in the background code. FindControls ("Coltrol Name") can manipulate controls in the DataGrid.
To control the state of the DataGrid containing controls when Datageid is in edit state, we can use CSS style definitions to add the following code to the
<style type= "Text/css" >.mytextbox {border-right: #000000 1px solid; Border-top: #000000 1px solid; font-size:9pt; Border-left: #000000 1px solid; width:80px; Border-bottom: #000000 1px solid; height:20px}
</style>

Overloaded DataBind () method to facilitate sorting in DataGrid

Ddl_da. Fill (ddl_table);
Regclientscript ();

Server-side functions that are triggered when the "edit" button is clicked
Set the panel's Visible property to false first because controls in the cell (such as a TextBox) will be Datageid when the DataGrid is in edit state
It's not easy to squeeze into the panel where we add records.

Panel1.visible = false;
Datagrid1.edititemindex = (int) E.item.itemindex;
