I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

public void gv_RowCreated(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int total = Convert.ToInt32(e.Row.Cells[1].Text) + Convert.ToInt32(e.Row.Cells[2].Text) + Convert.ToInt32(e.Row.Cells[3].Text) + Convert.ToInt32(e.Row.Cells[4].Text) + Convert.ToInt32(e.Row.Cells[5].Text) + Convert.ToInt32(e.Row.Cells[6].Text) + Convert.ToInt32(e.Row.Cells[7].Text);

Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .

I'm getting some Xml back from a service. I would like it to be the datasource of a grid view on my aspx page. Here is a sample of the Xml
<?xml version="1.0" encoding="utf-16" ?>
<ArrayOfTripTollCompleteDC xmlns:xsi=[URL]"
xmlns:xsd=[URL]>
<TripTollCompleteDC>
<TripTollId>5</TripTollId>
<DMSLaneModeID xsi:nil="true" />
<HOVOnly>false</HOVOnly>
<CreateDateTime>2010-06-07T15:54:01.023</CreateDateTime>
<ConfigVTMSDelaySeconds>5</ConfigVTMSDelaySeconds>
</TripTollCompleteDC>
and here is my code that parses the xml and tries to bind the grid. What am I missing here?
var retVal = service.GetTripDetailsByTripID(tripId);
var xmlTrips = XDocument.Parse(retVal);
var tripTolls =
from t in xmlTrips.Elements("TripTollCompleteDC")
select new {
TripTollId = (int)t.Element("TripTollId")
, DMSLaneModeID = (int?)t.Element("DMSLaneModeID")
, HOVOnly = (bool)t.Element("HOVOnly")
, CreateDateTime = (DateTime)t.Element("CreateDateTime")
, ConfigVTMSDelaySeconds = (int)t.Element("ConfigVTMSDelaySeconds")
};
grdTripDetails.DataSource = tripTolls;
grdTripDetails.DataBind();
I realize these are anonymous types. Is that a problem? I have verified the service is returning the Xml as stated above. Can anyone out there point me in the right direction? Just for completeness, here is the grid markup <asp:GridView runat="server" ID="grdTripDetails" />

I have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.

I am working in ASP .net 2.0. I am a learner. I have a grid view which has a button in it. find the asp mark up below
[Code]...
I was thinking that when I click the command button, it would fire the mygridview_rowcommand() but instead it threw an error as follows:
Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
