Access Data Values from NestedView Table

[Simon]

Hi

I have a Grid with NestedView Table which I create programmatically. 
Each row on the child table has a checkbox field which selects the whole row.
It has a custom Command header with an Image Button which is acting like an "Add to Cart" button.

When the button is clicked, I can access the selected child items like so:

if (e.CommandName == "AddToCart")
{

  if (RadGrid1.SelectedIndexes.Count == 0)

  {

     RadWindowManager1.RadAlert("No documents have been selected", 250, 100, "Add to Document Cart", "");

     return;

  }

  GridCommandItem Item = (GridCommandItem)e.Item;

  ImageButton btnAddToCart = (ImageButton)e.Item.FindControl("btnAddSelectedToCart");

  System.Collections.ArrayList doclist = new System.Collections.ArrayList();

  foreach (GridDataItem item in RadGrid1.SelectedItems)

  {

    doclist.Add(new HRTDocData(Convert.ToInt32(item["RecordID"].Text), Convert.ToInt32(item["DocID"].Text), item["DocTypes"].Text, item["DocReferences"].Text, item["DocContents"].Text));

  }

        }

I actually need to make a javascript call to some existing code with the list of selected items.  I have tried to access the same information from the client side but it isnt working - I just get null values - or not selected???
This is my js function

function GetChildValues() {
    var grid = $find("<%=RadGrid1.ClientID %>");
    var MasterTable = grid.get_masterTableView();
    var selectedRows = MasterTable.get_selectedItems();
    for (var i = 0; i < selectedRows.length; i++) {
        var row = selectedRows[i];
        var cell = MasterTable.getCellByColumnUniqueName(row, "RecordID")
        alert(cell);
    }

What am I missing please?

Hello Simon,

I suppose you want to show the cell text.Show the cell content using cell.innerHTML.
JS:

function GetChildValues()
{
  var grid = $find("<%=RadGrid1.ClientID %>");
  . . . .
  alert(cell.innerHTML);
}

Thanks,
Shinu.

Hi Shinu

Yes, you are correct - however, my problem is that it never reaches that code since the SelectedItems collection always seems to be empty.

ie.

selectedRows.length

is always 0.

I have resolved this now by referencing the RadGrid and not the MasterTable. ie.

    var grid = $find('<%=RadGrid1.ClientID %>');
var selectedRows = grid.get_selectedItems();

     if (selectedRows.length != 0) {

     for (var i = 0; i < selectedRows.length; i++) {

          var docReference = selectedRows[i].getDataKeyValue("DocReferences");

          var docId = selectedRows[i].getDataKeyValue("DocID");

          var currRef = selectedRows[i].getDataKeyValue('RecordID');

          alert("Reference: " + docReference + " - DocID = " + docId);

     }

     }

     else {

           radalert('No documents selected', 330, 100, 'Add to Cart', null); 

     }
