Sometimes you want to get a value that is not in the editing status. In this case, textbox is usually placed in the template column through E. Item. findcontrol. Why can't some netizens ask? This depends on how the columns on your front-end are written. The following describes four cases and the following value methods: 1 < ASP: DataGrid ID = "Datagrid1" Runat = "Server" Autogeneratecolumns = "False" Allowpaging = "True" >
2 < Columns >
3 < ASP: boundcolumn Datafield = "Vname" Headertext = "Name 0" > </ ASP: boundcolumn >
4 < ASP: templatecolumn Headertext = "Name 1" >
5 < Itemtemplate >
6 Name
7 </ Itemtemplate >
8 </ ASP: templatecolumn >
9 < ASP: templatecolumn Headertext = "Name 2" >
10 < Itemtemplate >
11 <% # Databinder.Eval(Container. dataitem,"Vname") %>
12 </ Itemtemplate >
13 </ ASP: templatecolumn >
14 < ASP: templatecolumn Headertext = "Name 3" >
15 < Itemtemplate >
16 < ASP: Label ID = "Name" Runat = "Server" Text = '<% # Databinder. eval (container. dataitem, "vname") % > '>
17 </ ASP: Label >
18 </ Itemtemplate >
19 </ ASP: templatecolumn >
20 < ASP: buttoncolumn Text = "Delete" Buttontype = "Pushbutton" Commandname = "Del" > </ ASP: buttoncolumn >
21 </ Columns >
22 </ ASP: DataGrid >
Lists four types of columns that you may encounter:
(1) bind Columns
(2) directly put static strings in the template Column
(3) directly include the bound string in the template Column
(4) Put the bound string in the template column using the label
The following describes the four values after the delete button is pressed:
1 If (E. commandname = " Del " )
2 {
3 Response. Write (maid [ 0 ]. Headertext + " : " + E. Item. cells [ 0 ]. Text + " <Br> " );
4 Response. Write (maid [ 1 ]. Headertext + " : " + E. Item. cells [ 1 ]. Text. Trim () + " <Br> " );
5 Response. Write (maid [ 2 ]. Headertext + " : " + (Databoundliteralcontrol) E. Item. cells [ 2 ]. Controls [ 0 ]). Text. Trim () + " <Br> " );
6 Response. Write (maid [ 3 ]. Headertext + " : " + (Label) E. Item. cells [ 3 ]. Findcontrol ( " Name " ). Text + " <Br> " );
7 }
(1) first, you can bind columns directly through cells [I]. text
(2) the second method can also be used directly, but the annoying vs.net always wrap the content in the column at the front end, therefore, we also need to remove spaces at the beginning and end of the output.
(3) the third method cannot directly use cells [I]. text to get the value, you can use the method given above to get, also need to remove spaces at the beginning and end
(4) The fourth method is the simplest way, of course, you can directly write e. item. findcontrol ("name")
