asp textbox not work with collapsed column on datatable

osma1k90

Hy to all
.. when i try to get via code the value of a input asp textbox it doesn't contain the right value. It return a sort of concatenation of the old and new value with comma. (Example if the initial value was "1,00" and i fill "3" then when i hit btnGetVal on server side i get "1,00,3"...)

i have a table in this asp page

<asp:UpdatePanel runat="server">
                    <ContentTemplate>                    
                        <asp:HiddenField ClientIDMode="Static" ID="id_p" runat="server" />
                        <table id="Gridv" class="responsive table table-striped table-bordered table-hover table-fixed-row" style="width: 100%">
                            <thead>
                                <tr>
                                    <th>D1</th>
                                    <th>D2</th>
                                    <th>Desc.</th>
                                    <th>Qta</th>
                                    <th>Pr.</th>
                                    <th></th>
                                    <th class="none"></th>
                                    <th style="display: none"></th>

                                </asp:Repeater>
                            </tbody>
                        </table>
                    </ContentTemplate>
                </asp:UpdatePanel>

code behind on server side when btnGetVal is fired i just want to get the data filled in the asp input txtCell_Qta.

```
protected void btnGetVal_Click(object sender, EventArgs e)
{

        foreach (RepeaterItem oRowRepeater in repGrid.Items)
        {
            if (oRowRepeater.ItemType == ListItemType.Item || oRowRepeater.ItemType == ListItemType.AlternatingItem)
            {
                HtmlTableCell nId = (HtmlTableCell)oRowRepeater.FindControl("val_k");


                if(nId.InnerText.ToString().Equals(id_p.Value))
                {

                    TextBox txtQ = (TextBox)oRowRepeater.FindControl("txtCell_Qta") as TextBox;
                    string qty = txtQ.Text;

                    //qty is dirty!!!!!
                    //Contains old value and new value comma separated...why?

                    //(Example   if the initial value was "1,00" and i fill "3" then i get "1,00,3"...) 
                    //                           


                }



            }
        }

        UpdGrid();
    }

```

i've used asp for several years but i never experienced a shitty situation like this...and i'm afraid. The only thing that i play around it's the class="none" on the column, because that way my html table collapse the columns with the input and button. It seems that if i remove class="none" and the cells are visible evrithing work as expected. But if i use this collapsing functionality on the table starts giving me this kind of result.... Unfortunately i need this collapsing feature of datatable.

Does anybody ever figured out this situation?
