Telerik Radgrid How to retrieve textbox values from dynamically generated RadGrid columns?

I am dynamically creating a RadGrid and adding GridTemplateColumns to it. Those columns have textbox in them.
After binding datatable to the grid, after user makes changes to the textboxes and on clicking save button, I would like to access the textbox values. But I am stuck at getting hold of the textbox instance. I couldn't even get hold of GridItems!
To add more complexity, my RadGrid is in a UserControl, which is in a (multi)view.
Since my control is in view, it's Page_Init is called more than once for each action that involves this view.

Once the gridstructure is defined, it has no need to change, but I think I should be calling it on Page Init or Load every time..

I have column paging instead of row paging, so there is custom code to handle that.
I would like to get some advice on the best place to call NeedDataSource, DefineGridStructure and where to get Postback values.
I have read this article, but it has sparse information for my need. http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html
Heres my code.

protected void Page_Init(object sender, EventArgs e)

{

DefineGridStructure();

}

      protected void Page_Load(object sender, EventArgs e)
      {
          if (RadGrid1 != null && RadGrid1.Items.Count > 0)
          {
              string strtxt = ((TextBox)RadGrid1.Items[1]["ProductGroup1"].Controls[0]).Text;//For starters, load one control and check it's state
          }
      }

private void DefineGridStructure()

{

RadGrid1 = new RadGrid();

RadGrid1.AutoGenerateColumns = false;

RadGrid1.ShowHeader = true;

RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

foreach(GridColumn qtyColumn in BuildGridQtyColumns(PaxColumnCount))

{

RadGrid1.MasterTableView.Columns.Add(qtyColumn);

}

//Add grid to page

phRadGrid.Controls.Add(RadGrid1);

}

private List<GridColumn> BuildGridQtyColumns(int count)

{

List<GridColumn> qtyColumns = new List<GridColumn>();

for (int i = 1; i <= count; i++)

{

string qtyColumnName = string.Format("ProductGroup{0}", i);

GridTemplateColumn qtyColumn = new GridTemplateColumn();

qtyColumn.ItemTemplate = new GridNumberTemplate(qtyColumnName);//Creates a textbox control

qtyColumn.UniqueName = qtyColumnName;

qtyColumn.HeaderText = "Qty";

qtyColumn.HeaderStyle.Width = Unit.Pixel(60);

qtyColumn.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

qtyColumns.Add(qtyColumn);

}

return qtyColumns;

}

Select all only selects items on first page

Within a RadGrid that uses the NeedDataSource method and using paging, there is a select all column. When the Header checkbox is selected, the items on the first page are selected only. How can I select all of the records within the RadGrid.

This is the code I have in place for selecting all dataitems:

CheckBox headerCheckBox = (sender as CheckBox);
foreach (GridDataItem dataItem in this.radgridmailinglists.MasterTableView.Items)
{
    (dataItem.FindControl("chxselectrow") as CheckBox).Checked = headerCheckBox.Checked;
    dataItem.Selected = headerCheckBox.Checked;
}

RadScriptManager and Firefox

Hello, I am having an issue with the RadScriptManager in Firefox. I'm trying to do a __doPostBack. And it is not working in Firefox. It works in every other browser but not FF. I noticed that the code generated from the script manager is not including the language=JavaScript param. Is this the issue. And if so how do I get the RadScriptManager to write that param.

Need to add only 12 labels to a graph

I have a graph that I'm dynamically creating. You can see it here http://www.cnppid.com/Assets/McConaughy_One-Year.jpg . How I'm building it is each day has a point. So this graph has an x range from 0 to 365. The problem is, I don't know how to add the labels so it only shows the month. Right now I have a data table with the y value, the x value, and what month it falls under. How do I make it so it shows the month label, but only once per month? Here's how I'm adding points to my graph.

For Each i As DataRow In rangeTable.Rows

myPoint.XValue = i("Count")

myPoint.YValue = i("Value")

myPoint.Label.Visible = False

mySeries.AddItem(myPoint)

Next

ComboBox no longer expands

I have a page that I am adding a wrapper div to after the page has been completely loaded. However, when this div is added, RadComboBoxes stop expanding or receiving input of any kind. Upon further testing, I found that the same happens for any control that has a popup div, such as datepickers. This is the code I'm using to add the div:

var body = GetFrameBody();

body.innerHTML = "<div id='reportwrapper' style='overflow:auto; position: relative;'>" + body.innerHTML + "</div>";

Thanks in advance for any help/insight you can offer.
