howto: embed a text box in a footer of a GridView's boundfield columnto get data prior to a row insert

Hi !



I need to embed a text box in a footer of a GridView's boundfield
column to get data prior to a row insert.



The textbox is usable and showing up in the web page source using View
Source, but I cannot see it using an alert,

or after postback on the server side (code behind). Is there a way to
reference such a control (embedded HTML in footertext) ?



If so, please advise ! (I embedded buttons in the command column which
work and execute their click events ok)



this code builds the footertext:



Dim grdBF As BoundField = New BoundField

grdBF.DataField = colNamesArray(idx)

'tbox

If colIsEditableArray(idx) = "false" Then grdBF.ReadOnly = True

'todo: style: grdBF.ApplyFormatInEditMode = True

'this always puts a textbox in if editable, todo: chg to add some
input control per type:

stCtrl = _

"<input id=""" & colNamesArray(idx) & "textbox"" Type=""Text""
size=""20"" maxlength=""30"" value="""">test</input>"

If colIsEditableArray(idx) = "true" Then grdBF.FooterText = stCtrl

dataGridView.Columns.Add(grdBF)



''''''''''''''''''''''''''''''''''''''

this code tries to access after postback, server side, but does not
work, fix needed:

Dim tb As HtmlInputText =
dataGridView.FooterRow.FindControl(colNamesArray(i dx) & "textbox")



''''''''''''''''''''''''''''''''''''

This code tries to show it client-side, at click event, before the
postback-submit:
(we can show only the innertext)



var state1 = document.getElementById("txtState");

var deForm = document.getElementById("form1");

state1.value = "insertclicked" //indicate state

//debug:

var tb = document.getElementById("dataGridView");

var i,j;

var msg;

for(i=0; i<tb.rows.length;i++)

{

msg += "\r\n" + tb.rows[i].cells[2].innerText;

}

alert(msg);

deForm.submit() //postback to server to save the data only

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
the fix must be server side in code behind, since this all must be
completely dynamic, and is dependent on a config file to get its table
data from a sqldatasource which requires the boundfields in this
gridview. fyi my templatefield columns all work fine, getting the data
back in the request object since its otherwise blown away by a
postback.

Regards !
