In the Gridview I have placed a buttonField for each row. The buttontype is Button and the commandname is Details. The text of this button is Details.
I know that when this button is clicked in a row, then the event fired is:
grid_RowCommand(object sender, GridViewCommandEventArgs e)

Question:
In this row, how can I get the value of the cells please?
thanks

i think you need the value of that row to display the details, if i am right then bind the commandargument field with Id. and as you
describe that commandname is fire then you get the value of commandargument.

hope this is fine with you,

if anything else please put your exact requirement.

You cannot get the row as e.row
use the following code

<br />
int index = Convert.ToInt32(e.CommandArgument);<br />
GridViewRow row = GridView1.Rows[index];<br />

There is also another way to get the row is

<br />
GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);<br />

Hope it help

Cheers!!

hi Brij,
Then how do I get the value of say cell 2 i.e ["name"] or 3 i.e. ["lastname"] ?

Note that this code returns "" whereas there is data in there.
grid.Rows[12].Cells[4].Text
return ""
Thanks

if you need the multiple data such as name,lastname etc. then bind the Id as CommandArgument field and when the row command fire make query in database passing with id (command argument value) and fetch the details of that row. in this way you get the multiple values.

if you need only single value such as lastname or name then bind the commandargument field with that field and rowcommand event you get this value using e.commangargument.

hope this is fine with you.

It should give ,please see it in the quickwatch that you are getting the actual row with all the controls or not..
I have used it several times...
if you some control on the row you can use row.findcontrol() mathod..

I can get this (see below) and there are template fields but I can not see anything else.
(int)grid.DataKeys[Convert.ToInt64(e.CommandArgument)].Values[0]

Iin case it helps you:
in grid_RowUpdating event, I can retrieve values fro mthe grid, i.e.:
string strID = grid.DataKeys[e.RowIndex].Value.ToString();
string strArchiveID = ((Label)grid.Rows[e.RowIndex].FindControl("lblArchiveID")).Text;

But can not retrieve anything except the key from the grid_RowCommand event

Any thoughts please?
Thanks

You cannot get the row as e.row.cell and e.row.cell.control
use the following code

int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = GridView1.Rows[index];
string Rating = ((TextBox)GridView1.Rows[Index].Cells[2].Controls[0]).Text;
string Rating = GridView1.Rows[Index].Cells[2].Text;

Hope it help

I get this error:
Cannot cast 'grid.Rows[index].Cells[5].Controls[0]' (which has an actual type of 'System.Web.UI.LiteralControl') to 'System.Web.UI.WebControls.TextBox'

p.s. some of the gridview fields are templatefields.
Anythoughts please?

arkiboys28-Jan-10 4:04

I even converted it to literalcontrol but returns just spaces in a string.
Not sure what is wrong?

I create 10 radcombobox and fill the values 1 to 10 in each Radcombobox.
This has done in code behind using c#.
I want to write the event for the radcombobox in the design code.
Evnnt is OnClientSelectedIndexChanged.
And i want to call the event from code behind.
During calling the java script function i have to pass some parameters.
This parameters may be the number of comboboxes and selected combobox id.
In the javascript function I have to done some operations using my logic.
If anybody know please post the answer.
