Gridview Row Databound Event

hello everyone,

i have three dropdowns.based on the dropdown selection grid was loaded.after the gridview load i edit a cell value then automatically aother cell values are changed

first select three dropdowns and click on the button.then the grid was loaded.i have rowdatabound event.at the first time of gridloaded rowdatabound event was fired.

after then i want to change the cell value. i write a javascript

function for calculating the formula.
and my rowdatabound event code is here

If e.Row.RowType = DataControlRowType.DataRow Then

Dim txt2 As TextBox = DirectCast(e.Row.FindControl("textbox2"), TextBox)
Dim txt3 As TextBox = DirectCast(e.Row.FindControl("textbox3"), TextBox)
Dim lbl1 As Label = DirectCast(e.Row.FindControl("label1"), Label)
If e.Row.RowState = DataControlRowState.Edit Then
lbl1.Text = DGV1.Rows(DGV1.SelectedIndex).Cells(3).Text
txt2.Text = DGV1.Rows(DGV1.SelectedIndex).Cells(4).Text
txt3.Text = DGV1.Rows(DGV1.SelectedIndex).Cells(5).Text
End If
Session("txt2") = txt2.Text
Session("txt3") = txt3.Text
Session("lbl1") = lbl1.Text
txt2.Attributes.Add("onblur", "GetDAmt('" & lbl1.Text & "','" & txt2.Text & "','" & txt3.Text & "');")
End If

javascript function

function GetDAmt(mAmt,mPAmt,mDAmt)
{
var mmAmt=0;
var mmPAmt=0;
var mmDAmt=2;

var mmAmt = "<% = Session("lbl1") %>";
alert(mmAmt);

var mmPAmt = "<% = Session("txt2") %>";
alert(mmPAmt);

var mmDAmt = "<% = Session("txt3") %>";
alert(mmDAmt);

mmAmt=document.getElementById(mAmt).value;
mmPAmt=document.getElementById(mPAmt).value;
if (!isNaN(mmAmt))
{
mmDAmt=mmAmt-mmPAmt;
}
document.getElementById(mDAmt).value=mmDAmt;

}

but after the cellv alue changed rowdata bound event was not fired.so the values are all '0's and it gives the value as 0.

what is the problem here.any one help me with this

well my friend a few things,

first thig you dont need the Session values

insted you can use

<% textbox.ClientID%> and so on in the JS

now regarding the RowDataBound it will occur only in the GridView Bind Command Call,
cellvaluechange does not call it, you can either fire the event on the cellvaluechange,
which i dont recommend since you will loose your changes, or create a submit botton to update the new records and then recall the gridview.DataBind event

hope this helps you out

This is very straight forward.

make this row editable by using edit button dont forget to make that button command name = 'edit' then on click of that button u need to display update and cancel button to update the cell values you changed.

i hope this will help you
