[Solved] SelectedItems returning zero

[bdk0172]

Have the following grid in my aspx page:

<telerik:RadGrid id="gridMessages" runat="server" AllowSorting="True" OnNeedDataSource="gridMessages_NeedDataSource"

AutoGenerateColumns="False" Skin="Office2007" AllowMultiRowSelection="True" Width="99%" EnableViewState="true" >

<MasterTableView Width="100%">

<Columns>

<telerik:GridClientSelectColumn Reorderable="False" UniqueName="ClientSelectColumn">

<HeaderStyle Width="20px"></HeaderStyle>

</telerik:GridClientSelectColumn>

<telerik:GridHyperLinkColumn DataNavigateUrlFields="msgtype,msggroupid,msgnumber" UniqueName="View"

DataNavigateUrlFormatString="MessageDetail.aspx?t={0}&g={1}&n={2}" Text="View" >

<ItemStyle ForeColor="Blue" />

</telerik:GridHyperLinkColumn>

<telerik:GridBoundColumn HeaderText="Type" DataField="msgtype" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Group" DataField="msggroupid">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Number" DataField="msgnumber" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Recv'd Date" DataField="recvdtdate">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Recv'd Time" DataField="recvdttime">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Tag" DataField="msgtag">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Description" DataField="msgdescription">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

</telerik:RadGrid>

I'm attempting to set up a Hashtable to the values from the grid with the following code:

        public List<Hashtable> getSelectedValues()
        {
            List<Hashtable> list = new List<Hashtable>();

            GridItemCollection items = gridMessages.SelectedItems;
            foreach (GridItem item in items)
            {
                Hashtable values = new Hashtable();
                ((GridDataItem)item).ExtractValues(values);
                list.Add(values);
            }

            return list;
        }

I can check any number of rows in the GridClientSelectColumn, but no matter what, gridMessages.SelectedItems is always zero.  Any ideas?

Hi,

The above given code was working fine on my end. Just give a try with the following approach and see whether you are getting the Selected items.

CS:

       List<Hashtable> list = new List<Hashtable>();
        foreach (GridDataItem item in RadGrid1.MasterTableView.GetSelectedItems())
        {
            Hashtable values = new Hashtable();
            ((GridDataItem)item).ExtractValues(values);
            list.Add(values);
        }

Thanks
Shinu.

This doesn't return any selected items either.  If I check radGrid.Items.Count, it returns the correct number of rows that are in the grid, so the code-behind is definitely able to access the grid.

Figured it out.  Moved the following code from Page_Load to Page_PreRender and my original code and your code both work:

gridMessages.DataSource =

null;

 

gridMessages.Rebind();
