Getting textbox's value in Nested gridview

I have a nested gridview, And there is a textbox that named TextBoxDescription to insert user information in the second gridview. But when I want to catch textbox's (TextBoxDescription) value its return Null.
Html Code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="100%"
DataKeyNames="ReportId" OnRowDataBound="GridView2_OnRowDataBound" ForeColor="#333333">

<Columns>
<asp:TemplateField>
<ItemStyle Width="35px" HorizontalAlign="Center" />
<ItemTemplate>
<img alt="" style="cursor: pointer" src="plus.png" />
<asp:Panel ID="Panel5" runat="server" Style="display: none; text-align: center;">
<asp:GridView ID="GridView2" border="0" runat="server" DataKeyNames ="ReportId" OnRowCommand="GridView1_RowCommand"

</asp:GridView>
.

.
C# Code:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "updateData")
{
int i = Convert.ToInt32(e.CommandArgument);
GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
TextBox tb = (TextBox)row.FindControl("TextBoxDescription");
string Text = tb.Text;
}
}

Do like below :
GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
int index = row.RowIndex;
TextBox tb= (TextBox )GridView1.Rows[index].FindControl("TextBoxDescription");

ASP.Net gridview not refreshing when used with Ajaxtoolkit Upload control

I have an asp.net web page that allows for manual entry of a record, or an import from an excel spreadsheet to import multiple records.
After the records are added by either process, they display in a Gridview control (bound to a SQLDataReader). This allows the user to edit or delete a record before submitting the entire dataset for processing.
I'm using an Ajax Toolkit AsyncFileUpload control to handle the import. The UploadedComplete c# function runs properly and the records are inserted into the SQL table. The code then calls my DataBindGrid() function to refresh the grid. I can step through the code and see that every line is executing, however, it seems like it never actually finishes, even though stepping through debugging completes.
Two steps are not actually completing, the grid refresh and the label display that indicates to the user that the process is complete.
For testing purposes, I've added a linkButton that calls the BindDataGrid() when clicked. This works to refresh the grid and to also display the status label. It's not a permanent solution, it would be too risky to have a user remember to refresh, they are likely to think that all their records have already been submitted.
At first I thought my problem was trying to do more inside the UploadComplete function then just upload the file (I'm reading the Excel file that was uploaded), so I broke out the code and added a button for the user to click to initiate the actual data processing. This failed because although I could see the file name being saved into a hidden form during the UploadComplete function, when I went to read that hidden field, the data was no longer in it. I'm not loosing the values in any of the other hidden fields.
I've been researching this for 3 days and I'm really stuck. I'm assuming that I am having a problem with postback, but have no clue at this point.
Here is my code:

As u can see the second gidview named id is ShowFoodMenu2 and it's inside first girdview which id Giridview1 .
and also I have two Linkbuttons inside the second gridview
one of them keep the value(which is LinkButton12) and another one(LinkButton2) is for when I clicked it add a record in Database .
But when I clicked on Linkbutton(LinkButton2) to show the value of Linkbutton12 , I will get ann error
Here is the error
http://hidelion.com/Images/error.png
and here is my.cs code
protected void LinkButton2_Click(object sender, EventArgs e)
{
GridView G = new GridView();
G.FindControl("ShowFoodMenu2");
System.Threading.Thread.Sleep(1000);
LinkButton m = (LinkButton)sender;
int i = Int32.Parse(m.CommandArgument);
LinkButton LblMososID = (LinkButton)G.Rows[i].FindControl("LinkButton2");
// LinkButton LblMososID2 = (LinkButton)G.Rows[i].FindControl("LinkButton12");
Label1.Text = LblMososID.Text;
}
So how can I solved this problem ??????

GridView G = new GridView(); just create a new instance of Gridview class, and it will not find your gridview automatically, You are messing it up, simply go like this, from linkbutton find the corresponding row, from that row fetch the control you wish to manipulate, do it like this:-
protected void LinkButton2_Click(object sender, EventArgs e)
{
LinkButton LinkButton2 = sender as LinkButton;
GridViewRow grdRow = (GridViewRow)LinkButton2.NamingContainer;
LinkButton LinkButton12 = (LinkButton)grdRow.FindControl("LinkButton12 ");
Label1.Text = LinkButton12.Text;
}

Cannot get the selected Gridrow value on a buttonClick MVC, C#

Im trying to get the values in a specific gridview row when clickin on it or when clicking on a button.
The problem is that nothing happen when i click on the row, Not even when i click on the button.
The rows are unclickable.

Lina,
Although i don't have the answer for your problem I have however found a data consistency issue.
When your scrolling through the checkboxes you are overtyping the Label5.Text each time. Therefore the scrolling is pointless as Label5 will only ever show the value of the last Checkbox it found to have been ticked.
May i suggest the following alternative:
CheckBox x;
foreach (DataGridItem di in GridView1.Rows)
{
x = (CheckBox)di.FindControl("checkBox1");
if (x.Checked == true)
{
if(Label5.Text == "")
{Label5.Text = GridView1.SelectedRow.Cells[2].Text;}
else {Label5.Text = Label5.Text + " - " + GridView1.SelectedRow.Cells[2].Text;}
}
}
This will at least append the data onto the string seperating it with " - " if there are more the 1 Checkboxs selected. Feel free to change the separator as required.

When I upload the file , I want the giedview which is in the child updatepanel to be updated .But it doesnt work Any ideas?????
thanks in advance

Call child.Update(); in BrochureUpload_UploadedComplete event.
protected void BrochureUpload_UploadedComplete(object sender, AsyncFileUploadEventArgs e)
{
....................
....................
bindGridView();//I have code to bind gridview
child.Update();
}

When file upload is complete then call Child.Update() method of UpdatePanel which contain gridview. You need to do that because you set UpdateMode="Conditional" in this case you have to manually update it in code.

ChildrenAsTriggers="True" in your updatepanel.
