Datagrid|datagrid Controls | templates | Data bulk get data in the DataGrid control template column
In a DataGrid, you can usually only get data for each row individually, and to bulk get the data in the DataGrid control you must scan the controls for each template column to get the data.
I want to do the program is based on the number of different lines, the user input a number of data at a time, submitted after the system to automatically obtain batch data program.
The following program simply expresses the functionality that needs to be implemented
Test.aspx
..........
<asp:datagrid id= "Dgresult" runat= "Server" bordercolor= "#DEBA84" borderstyle= "None" cellspacing= "2"
Borderwidth= "1px" backcolor= "#DEBA84" cellpadding= "3" autogeneratecolumns= "False" >
<footerstyle forecolor= "#8C4510" backcolor= "#F7DFB5" ></FooterStyle>
<selecteditemstyle font-bold= "True" forecolor= "white" backcolor= "#738A9C" ></SelectedItemStyle>
<itemstyle forecolor= "#8C4510" backcolor= "#FFF7E7" ></ItemStyle>
<Columns>
<asp:boundcolumn datafield= "id" headertext= "column number" ></asp:BoundColumn>
<asp:templatecolumn headertext= "column name" >
<ItemTemplate>
<asp:textbox runat= "Server" enabled= "True" width= "id=" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:templatecolumn headertext= "integer precision" >
<ItemTemplate>
<asp:textbox runat= "Server" enabled= "True" id= "Textbox1" width= "M" >20</asp:TextBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:templatecolumn headertext= "decimal point Precision" >
<ItemTemplate>
<asp:textbox runat= "Server" enabled= "True" id= "Textbox2" width= "M" >10</asp:TextBox>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
<pagerstyle horizontalalign= "Center" forecolor= "#8C4510" mode= "NumericPages" ></PagerStyle>
</asp:DataGrid>
<asp:button id= "Btnok" runat= "Server" text= "Submit" ></asp:Button>

Test.aspx.cs
private void Page_Load (object sender, System.EventArgs e)
{
Place user code here to initialize page
if (! IsPostBack)
Mfbind (DataSource ());
}
Private IList DataSource ()
{
DataTable dt=new DataTable ();
DataColumn dc=new DataColumn ();
dc. Columnname= "id";
dc. Datatype=system.type.gettype ("System.Int32");
dc. Readonly=true;
dc. Unique=true;
dc. Autoincrement=true;
dc. Autoincrementseed=0;
dc. Autoincrementstep=1;
Dt. Columns.Add (DC);
Dc=new DataColumn ();
dc. Columnname= "column name";
dc. Datatype=system.type.gettype ("System.String");
Dt. Columns.Add (DC);
for (int i=0;i<10;i++)
{
DataRow Dr=dt. NewRow ();
Dr[1]=i;
Dt. Rows.Add (DR);
}
session["Source" = DT;
Return dt. DefaultView;
}
private void Mfbind (IList dv)
{
This.dgresult.datasource= (DataView) DV;
This.dgResult.DataBind ();
}
private void Btnok_click (object sender, System.EventArgs e)
{
String tmpa=dgresult__ctl2_col1. Text;
TextBox txt;
ArrayList marr=new ArrayList ();
for (int i=0;i<10;i++)
{
Txt=new TextBox ();
txt= (TextBox) dgresult.items[i]. FindControl ("col");
Marr.add (txt. Text);
}
for (int i=0;i<marr.count;i++)
This.lblproblem.text+=marr[i]. ToString () + "; ";
}
In fact, such programs have commonality, through the DataGrid control can batch processing of data, especially in the process of deleting data and other operations to use and convenient, as long as the program's template column in the TextBox control to the CheckBox control or DropDownList control , scanning all the child controls can realize the bulk of the data quickly delete, modify, and other operations.
