Why Application_PostAuthenticateRequest and Application_AuthenticateRequest events happen twice ? When I put a breakpoint in their code I see that when I run the application they are called twice ? Can someone tell me why they have to be called twice ? Illustrating their position in the asp.net's events flowchart will be helpful . Help me please .

Hi,
In my project,due to large number of records a stored procedure is taking more time to return the records.But before that the connection time expires and the module will show the error message.Since the project is deployed in the site we cannot recompile after code change.Is there any way to set in web.config to get more sql connection time.
Please show me the right way..Thanks much in advance.
Thank You,
RPM.

You can set the CommandTimeout[^] property of your SqlCommand object to a higher number before executing.

Hi Mike Ellison,
Thanks a lot for the reply and information.But this requires code change.Our project is deployed in the production server.So without a code change and only change in web.config can we incorporate this?
Any possibility is there?
Thanks very much,
RPM.

Well, you can always store values in AppSettings in your web.config, then read those values in your application... granted, that involves a code change initially, but after that then you can set your timeout values through web.config.

I have faced the similar problem in my application. To change the connection timeout property in the query string won't solve the issue. You have to change on the code, imagine you are using an command object and executing a stored procedure, you have to set the CommandTimeout property of the command object to some time (Seconds). It is working for me. I tried with web.config connection timeout property of the connection string, it was not working.
Example:
========
SqlCommand oCmd = new SqlCommand("Procedure1", oConn);
oCmd.CommandType = CommandType.StoredProcedure;
oCmd.CommandTimeout = 300;
SqlDataAdapter oAdp = new SqlDataAdapter(oCmd);

hi,
i have seen some of the datagrid samples in internet. In most of the cases the datagrid is bind to some table. But if i want to display the output of an sql query(contains select statement with n number of columns) in Datagrid, i can simply use AutogenerateColumns=true and populate the datagrid without having any bound columns. That is fine.
If i want to add some more extra columns like a checkbox column and an edit link button column i can do it using property builder. But,the problem is how can i order the columns in datagrid.
for example: 1st col: checkboxes
2nd-4th col : from sql statemnt
5th col : edit link button
Also how can i make a random column from sql statement to a hyperlink column.
thanks

One simplest way is, add few temprory columns in the query, wherever you want add column in the grid. Then bind that query result to the datagrid.
Example:
========
Actual query is,
select column1, column2, column3 from table1
Imagine you want to add columns in between 1 and 2, 2 and 3 then the query should be,
select column1, '' as tempcol1, column2, '' as tempcol2, column3 from table1
then on the itemdatabound event you can add any control like (button, linkbutton, or dropdownlist) on the column.

then on the itemdatabound event you can add any control like (button, linkbutton, or dropdownlist) on the column
Explanation:
============
You just execute the these two queries. First query will return three columns, second query will return five columns. The temp columns are not available in any table, which will be used to create a column in the grid. You just execute this queries in the query analyzer and check.

Hi,
I have a problem with event on LinkButton inside my TemplateField of GridView which is programmatically created.
When I create GridView's TemplateField, I use special class that inherits from ITemplate.
In this class I try to create LinkButton for every row of GridView.
This is my code:
class GridViewTemplate : System.Web.UI.Page, ITemplate<br />
{<br />
ListItemType templateType;<br />
string columnName;<br />
<br />
void ITemplate.InstantiateIn(System.Web.UI.Control container)<br />
{<br />
switch (templateType)<br />
{<br />
case ListItemType.Item:<br />
LinkButton lbtn = new LinkButton();<br />
lbtn.DataBinding += new EventHandler(Object_DataBinding);<br />
lbtn.CssClass = "TextBlackBold";<br />
lbtn.Command += new CommandEventHandler(this.TakeTaskLinkButton_OnCommand);<br />
lbtn.CommandName = "SubmitTakeTaskLinkButtonCommandName";<br />
container.Controls.Add(lbtn);<br />
break;<br />
}<br />
}<br />
<br />
void Object_DataBinding(object sender, EventArgs e)<br />
{<br />
LinkButton lbtn = (LinkButton)sender;<br />
GridViewRow container = (GridViewRow)lbtn.NamingContainer;<br />
lbtn.ID = "TakeTaskLinkButton" + DataBinder.Eval(container.DataItem, "taskid").ToString();<br />
lbtn.Text = DataBinder.Eval(container.DataItem, "tasktitle").ToString();<br />
lbtn.CommandArgument = DataBinder.Eval(container.DataItem, "taskid").ToString();<br />
}<br />
<br />
void TakeTaskLinkButton_OnCommand(object sender, CommandEventArgs e)<br />
{<br />
switch (e.CommandName)<br />
{<br />
case "SubmitTakeTaskLinkButtonCommandName":<br />
Response.Redirect("Default.aspx");<br />
break;<br />
}<br />
}<br />
<br />
public GridViewTemplate(ListItemType type, string colName)<br />
{<br />
templateType = type;<br />
columnName = colName;<br />
}<br />
}
and the TakeTaskLinkButton_OnCommand method is not fired when I click on the LinkButton.
I don't know why!? Any suggestions? How can I solve this problem?
Regards,
(Sorry for any mistakes)

Yes paypal has got .net SDK which can be use to connect to paypal server and do all the validation.

what i have to do just pay the payment after calculation.
in my website there is no such Add to Cart Like thing.
user just can click on the plan and for how many month he want this plan.
suppose one plan cost is 1$ for a month.if he select For 2 Month.then total amount is 2$.
now how to payment this 2$ using paypal.
if u hav some REF: Code then plz send me if possible otherwise guide me.

Hi,
So you want a code that will send credit card number and others details and verifiy and tell you if valid or not.
check this link and download the sample of paypal with asp.net. I have the functionality of adding to cart but can just ignore the cart functionality and check how credut card validation and verfication is done.
hope it helps.
If time permit I will send you a sample for this validation.
Regards,
Anil
