Get all checked values from GridClientSelectColumn

[Bruno]

Hi everybody, as my title says, i have a GridClientSelectColumn, on my radGrid, and a button outside this grid, in this button, i try to get all checked check box on this way:

protected void btnDel_Click(object sender, EventArgs e)
{
    string id;
    bool chec;
    foreach (GridDataItem item in RadGrid2.Items)
    {
        CheckBox chk = (CheckBox)item["CheckboxColumn"].Controls[0];
        id = item["codigo"].Text;
        chec= chk.Checked;
    }
}

but if i try this way, i will get one by one valuee from checkbox that are checked.
Exist some way to get ALL rows that my gridClient are selected?
Thankz in advance

Hello,

I guess you want to loop through all selected rows.Check the following code.
C#:

foreach (GridDataItem item in RadGrid2.SelectedItems)
{
    //your code
}

Thanks,
Princy.

I try to loop all selected item like this but its only download/print for the first item only. Could anyone help to advise?

notes: optListCCl is a radio button list.

foreach (GridDataItem item in RadGrid1.SelectedItems)
            {
                CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];
                
                SelectedItemLbl = item["FILENAME"].Text;
                cclID = item.GetDataKeyValue("ID").ToString();
                deliveryId = item["DELIVERY_ID"].Text;

                string filepath = SelectedItemLbl;
                chec = chk.Checked;

                if (optListCCl.SelectedItem.Value == "1")
                {
                    //Print Only
                    PrintOutContent();
                }
                else if(optListCCl.SelectedItem.Value == "2")
                {
                    //Download Only
                    downloadFile(SelectedItemLbl);
                }
            }

Hi Had,

The shared code appears to loop through all checked instances of the Grid rows, can you please check both functions being called and see if something in them breaks the loop?

Additionally, the following forum threads related to your question may help you out:

Hi,

I have a rad grid with paging enabled.I select all rows in multiple pages using a GridClientSelectColumn. When I click on print button it prints only the records which are displayed in first page,not all records selected in multiple pages. How to fix it. Plz help...

 

This is how i selected all checkboxes in multiple pages.

 var selected = {};
                function radGridWarehouseUtility_RowSelected(sender, args) {
                    var LID = args.getDataKeyValue("LID");
                    if (!selected[LID]) {
                        selected[LID] = true;
                    }
                }

                function radGridWarehouseUtility_RowDeselected(sender, args) {
                    var LID = args.getDataKeyValue("LID");
                    if (selected[LID]) {
                        selected[LID] = null;
                    }
                }

               function pageLoad() {
                   var dataItems = $find('<%=radGridWarehouseUtility.ClientID %>').get_masterTableView().get_dataItems();
                   for (var i = 0, j = dataItems.length; i < j; i++) {
                       var item = dataItems[i];
                       if (selected[item.getDataKeyValue("LID")]) {
                           item.set_selected(true);
                       }
                   }
               }

 

                        <ClientSettings EnablePostBackOnRowClick="true">
                            <Selecting AllowRowSelect="True"></Selecting>
                            <ClientEvents OnRowSelected="radGridWarehouseUtility_RowSelected"
                                OnRowDeselected="radGridWarehouseUtility_RowDeselected" />
                        </ClientSettings>

 

<telerik:GridClientSelectColumn UniqueName="Select" />

 

code behind...

 

Protected Sub btnPrint_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnPrint.Click

 For Each item As GridDataItem In radGridWarehouseUtility.SelectedItems
            Dim item1 As GridDataItem = item
            Dim chkBox As CheckBox
            chkBox = DirectCast(item1.Item("Select").Controls(0), CheckBox)

            If chkBox.Enabled Then
                Dim lid As String
                lid = CType(radGridWarehouseUtility.MasterTableView.DataKeyValues(item.ItemIndex)("LID"), String)
                qryParams = qryParams & lid & ","
            End If
        Next

End Sub

 

Thanks
