6. Select data from client and get field value

1. Select or deselect all rows on the page
Using the Selectallrowsonpage method
Grammar 1:void Selectallrowsonpage ()
Syntax 2:void selectallrowsonpage (bool selected)
Parameter selected indicates that all rows are selected or deselected

2. Select or cancel the specified line or all rows
(1) Selectrows method (selects data based on the index of the row)
Grammar 1:void Selectrows ()
Select All records (including records that are not the current page)

Syntax 2:void selectrows (int visibleindex)
Select the specified row data, but before you have to set Keyfieldname, which is the Aspxgridview primary key

Syntax 3:void selectrows (int32[] visibleindces)
Select a specified number of rows of data

Syntax 4:void selectrows (int visibleindex,bool selected)
Selects or de-selects the specified data, and the parameter selected indicates that all rows are selected or deselected

Syntax 5:void selectrows (int32[] Visibleindces,bool selected)
Select or deselect the specified multiline data, and the parameter selected indicates that all rows are selected or deselected

Example: We want to check the 第1-10 row data in Aspxgridveiw

 var  rows = new   Array ();  for  (var  i = 0 ; i < 10 ; I++ = I;} Grid. Selectrows (rows);  //  Note: Grid is Aspxgridview client ID, not runat  

(2) Selectrowsbykey method (selects data based on the value of the primary key, provided that the primary key, or Keyfieldname property, must be set for Aspxgridview)
Syntax 1:void Selectrowsbykey (object key)
Select row data for the specified primary key value

Grammar 2:void Selectrowsbykey (object[] keys)
Select multiple rows of data for the specified primary key value collection

Syntax 3:void Selectrowsbykey (object key, bool selected);
Select or deselect row data for the specified primary key value, and the parameter selected indicates that all rows are selected or deselected

Grammar 4:void Selectrowsbykey (object[] keys, BOOL selected);
Selects or cancels the selection of multiple rows of data for the specified primary key value collection, and the parameter selected indicates that all rows are selected or deselected

3. Get the selected line information
(1) Gets the number of rows selected
Syntax: Int getselectedrowcount ()

(2) Gets the selected row field value
function getselectedfieldvalues (fieldnames:string,oncallback:aspxclientgridviewvaluescallback);
Example:

function Getselectedfieldvalues () {varFieldNames ="Logid"; Grid. Getselectedfieldvalues (FieldNames, getselectedfieldvalues_callback);} function Getselectedfieldvalues_callback (result) {varmsg=""; if(Result.length >0) {         for(vari =0; i < result.length; i++) {msg= msg +result[i].tostring (); }} alert (msg);}

Note : Many foreground values for Aspxgridview are performed in the callback function.

4. Cancel selection of all rows on the page
(1) Unselectallrowsonpage method
Syntax: void Unselectallrowsonpage ()

5. Cancel the selection of the specified line or all rows
(1) Unselectrowonpage method
Syntax: function unselectrowonpage (visibleindex:int);

(2) Unselectrows method (deselect data based on row index)
Syntax 1:void unselectrows ();//Cancel selection of all rows
Syntax 2:void unselectrows (int visibleindex);//cancels the selection of the specified row
Grammar 3:void unselectrows (int32[] visibleindices); Cancel the selection of a specified range of insiders

(3) Unselectrowsbykey method (deselect the data based on the value of the primary key, if the primary key must be set for Aspxgridview)
Grammar 1:void Unselectrowsbykey (object[] keys);
Syntax 2:void Unselectrowsbykey (object key);
