Viewstate problem

[Jouni]

Hello everybody,

First i have to tell you little pit background about my case. I have RadGrid is in edit mode all the time.I put grid in the edit mode using following function:

  protected void RadGrid1_PreRender(object sender, EventArgs e)
        {
            if (!IsPostBack||forceEditable)
            {
                forceEditable = false;

                foreach (GridItem item in RadGrid1.MasterTableView.Items)
                {
                    if (item is GridEditableItem)
                    {
                        GridEditableItem editableItem = item as GridDataItem;
                        editableItem.Edit = true;
                    }
                }
         }
}
}

my problem is too big viewstate. So I decieded to turn page viewstate to false. Now problem starts.I collect data from using following function

 private void CollectRowInformation()
        {
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
            {
                foreach (OrderLineItem lineItem in OrderLine)
                {
                    int itemId = int.Parse(item.GetDataKeyValue("OrderLineID").ToString());
                    int lineId = lineItem.OrderLineID;
                    if (itemId == lineId)
                    {


                        lineItem.Product = (item["Product"].FindControl("ProductCombo") as RadComboBox).Text;
                        lineItem.Unit = (item["Unit"].Controls[0] as TextBox).Text;
                        lineItem.Info = (item["Product"].FindControl("InfoTextBox") as RadComboBox).Text;
                        lineItem.AccountID = (item.FindControl("AccountID") as RadComboBox).SelectedValue;
                        lineItem.CostCenterID = (item.FindControl("CostCenterID") as RadComboBox).SelectedValue;
                        if ((item["Quantity"].FindControl("Quantity") as RadNumericTextBox).DbValue == null)
                            lineItem.Quantity = 0;
                        else
                            lineItem.Quantity = float.Parse((item["Quantity"].FindControl("Quantity") as RadNumericTextBox).DbValue.ToString());
                        if((item["Price"].FindControl("Price") as RadNumericTextBox).DbValue==null)
                            lineItem.Price = 0;
                        else
                           lineItem.Price = float.Parse((item["Price"].FindControl("Price") as RadNumericTextBox).DbValue.ToString());
                        lineItem.Position = int.Parse((item["Position"].Controls[0] as TextBox).Text);
                        if ((item["EstimatedDeliveryDate"].FindControl("EstimatedDeliveryDate") as RadDatePicker).DbSelectedDate == null)
                            (item["EstimatedDeliveryDate"].FindControl("EstimatedDeliveryDate") as RadDatePicker).DbSelectedDate = DateTime.Now;

                        lineItem.EstimatedDeliveryDate =(DateTime)(item["EstimatedDeliveryDate"].FindControl("EstimatedDeliveryDate") as RadDatePicker).SelectedDate;
                        lineItem.Received = (item.FindControl("Received") as CheckBox).Checked;
                        lineItem.Invoiced = (item.FindControl("Invoiced")  as CheckBox).Checked;
                        //lines.Add(lineItem);


                    }


                }
            }

lineItem.Product = (item["Product"].FindControl("ProductCombo") as RadComboBox).Text; gives me Null.actually every single control returns null reference.when page viewstate is true.everythink works fine .What seems to be problem.Is there any other way handle big viewstate?

Hi Jouni ,

Instead of disabling ViewSate you can compress it - please check this post for more info:
