[Solved] Access Read Only and Hidden Fields in RadGrid (in Edit Mode)

[Noha]

Dear all

I have a RadGrid contains 3 columns as below:
 

<telerik:GridBoundColumn DataField="ID" HeaderText="ID"
    ReadOnly="True" UniqueName="column1">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Seller" HeaderText="Seller"
    ReadOnly="True" UniqueName="column2">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Amount" HeaderText="Amount"
    UniqueName="column3">
</telerik:GridBoundColumn>

2 of them are read only and user can only edit in column3.

I get the edited item as below:

But I can't get the value of the first column , the "ID" ?!!!!

protected void grdSellers_ItemCommand(object source, GridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "Update":
            GridEditableItem editedItem = e.Item as GridEditableItem;
            TableCell cell = editedItem["column3"];
            string itemValue = (cell.Controls[0] as TextBox).Text;

            //Get Id of editable item ??
    }
}

I tried the solution in this post:
http://www.telerik.com/community/forums/aspnet-ajax/grid/accessing-readonly-hidden-fields-in-edit-mode-radgrid.aspx

but it generate error about ParentItem !

Could any one help me in that issue ??

Hello Noha,


One suggestion is setting the DataKeyNames and accessing the value using the "GetDataKeyValue" method. Here is the sample code.
            string itemValue = editedItem.GetDataKeyValue("ID").ToString();


Also the following code worked fine for me.

C#:

protected void grdSellers_ItemCommand(object source, GridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "Update":
            GridEditableItem editedItem = e.Item as GridEditableItem;
            TableCell cell = editedItem["column1"];  //access cell using ColumnUniqueName
            string id = (cell.Controls[0] as TextBox).Text;// get id
     }
}

Thanks,
Princy.

string itemValue = (cell.Controls[0] as TextBox).Text;
