Try this
string str = GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Values["here datakeyname"].ToString();
and in the source, for CommandArgument..
CommandArgument='<%#((GridViewRow)Container).RowIndex %>'

The event that is firing is an onclick event for the dropdownlist
Therefore
string str = GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Values[""].ToString();
does not work because there is no command arguement for it
is there another way?
thanks

Post your code where you create event handler of dropdownlist and dropdownlist event also

DropDownList dr = (DropDownList)sender;
string str = GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Values["code"].ToString();
SqlCommand cmd_update_order = new SqlCommand("update_order", con);
cmd_update_order.CommandType = CommandType.StoredProcedure;
cmd_update_order.Parameters.Add(new SqlParameter("@order", SqlDbType.Int));
cmd_update_order.Parameters["@order"].Value = dr.SelectedValue;
cmd_update_order.Parameters.Add(new SqlParameter("@code", SqlDbType.VarChar));
cmd_update_order.Parameters["@code"].Value = str;
str should be the datakey but it is not working
thanks

You can not get CommandArgument here
Set that in ToolTip property of dropdownlist when you create evend handler of DDL
On RowCreatedEvent
DropDownList ddl=(DropDownList)e.Row.FindControl("DDLID");
ddl.ToolTip=gv.DataKeys[e.Row.RowIndex].Value;
Now on SelectedIndexChange event
DropDownList dr = (DropDownList)sender;
string keyID=dr.ToolTip
....

error:
Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)
ddl.ToolTip = GridView1.DataKeys[e.Row.RowIndex].Value; // gv is your gridview
it throws an error for this line
How do I convert?
|
|
|
|
|
ok I changed to
ddl.ToolTip = GridView1.DataKeys[e.Row.RowIndex].Value.ToString();
and it now it shows
Index was out of range. Must be non-negative and less than the size of the collection.
why would this be?
cheers

Use the NamingContainer property of your DropDownList
So in your OnSelectedIndexChanged you can state
(GridViewRow) row = (GridViewRow)ddl.NamingContainer;
After that you can set
GridView.SelectedIndex = row.RowIndex;
At the end of the event add a line:
GridView.SelectedIndex = -1;
you do this to prevent showing a GridView with a Selected Line in it.

I'm trying to deploy my asp.net 2.0 on windows server 2003. The login page of the web application (default) works fine but when I try to login, the page keeps loading and loading for a long time and I never accesses the pages after login. No error is displayed or anything the browser just hangs as if it's trying to access the page.
I'm using the membership api in asp.net and I installed the ajax extensions on the server and I created a virtual directory in the iis.
what's wrong?

Please check the server even viewer to see whats the error. Post whats happening else its almost impossible to help you out I guess.

Thank u...,
I am trying to allocate width for my gridview columns...,
In my rowdatabound i given
e.row.cells[3].width=Unit.Pixel(100);
e.Row.Cells[3].Wrap = true;
Its not at all considered the values, what i have allocated the cell...,
Based on grid total width its automatically allocated the width for cells...,
So i changed my code like this:
e.Row.Cells[3].Attributes.Add("width", "100px;");
Its worked cool...,
Now my probs is, suppose the text is continious text...,
That time its not warpping the text based on the allocated width...,
Eg text like this : copy_text_normal_ppojkjbjhjh_bvjhvkv_jnvjhb.txt
Now this text having no gap between the letters...,
In that case its not at all wrapping my text based on the width of the cell,
How to solve this probs

Generally in this situation,Overflow style can be used.
You can add overflow attribute style and set it as scroll or hidden.
i.e
e.Row.Cells[3].Attributes.Add("overflow","scroll");
OR
e.Row.Cells[3].Attributes.Add("overflow","hidden");

hi every one .
i have a query .actually i am taking a selected value of the dropdown box in session variable .at second page the value of session variable remains 2. if i select 2 from drop down box at page 1.but at page three it gives the value of session 1 (the intial value of dropdownbox) .
plz advice what should i do.
thanks...gaurav

The value of a session variable doesn't change by itself, so somewhere you have code that changes it.
Despite everything, the person most likely to be fooling you next is yourself.
