Hi,
I am designing a form with a DataGrid and other server controls, TextBox, Calendar, ListBox etc. The idea is at page load the grid would be filled, when user clicks a row in the grid, the controls below would be filled with data in the grid so that user may edit data and submit again.
However, everytime I click a row, the validators in the conrols below are firing. Say, one textbox is not filled by data from Grid, but it has a custom validator, it will fire when user clicks a row. Its annoying because this form has lots of controls with validators and the moment I click the row in Grid, lots of required field and custom validator errors would fill the validator summary.
Could anyone suggest how to avoid this?
Regards,
Blumen

set the "CausesValidation" property of that control to false

cant set the causesvalidation to false because validators has to fire when data is entered in those controls and Submit button is clicked, but not when a row in the grid is clicked.
|
|
|
|
|
what is that server control(child control) used to click the item in the grid?
change the "causesvalidation" property of that child control. keep the causesvalidation property of the submit button the same. Let the validation happen when you submit the page, not when you fetch the data during postback.

I'm directly clicking on the grid rows, not any child controls. The grid has a hidden cloumn, which has a unique id. This id is unique for every row. I'm using this id on row click and getting data from the database, with data I fill the controls below the Grid.
So this is the scenario. What can I do now?
Regards,
Blumen

try this ValidateRequest=false in your page directive of your asp.net page,, but there are security concerns

Page validation should not be turned OFF when there is a need to validate the data on submit.
To disable validation for any control on the page, need to set the control's CausesValidation property to false

Hi,
I have a problem. How do you send xml file (or data in xml file or in string) from one aspx page to other aspx page. Remember that the other aspx page is different application. we can't use context here.
The content of the xml is more to accomodate through Query String. Can some body help me
Thanks in advance

store the XML file into database and pass the ID in the query string and retrieve it from the database in the other aspx page...

No. We have to pass that one as string only. That application can be able to read the string through the query string only. that application is a III party application where we can't handle.
Thanks,

Store the XML either on Disk or Database and pass the 3rd party an ID to that XML. Then provide them with a WebService that accepts the ID and returns the correct XML. This way you can avoid trying to pass a huge XML document through the QueryString.

If the other page is a different application, then you're kind of stuck, the query string is your only hope.

i have a table named emp.
where one coloumn named "status",
which doesnot take any value from the front end.i am storing its default valus as"ON" in the emp table which is set in its cloumn property .
and another table emp_detail where one column named "eligible".( both tables are related with each other by "emp_id" coloumn)where it takes the value from the frontend either "Y" or "N".now i want if the value for "eligible" is stored as "Y".then the corresponding record of that in the "emp"table should be updated that is only the "status " column set to be OFF.
where it takes the value from the frontend either "Y" or "N".
now i want if the value for "eligible" is stored as "Y".then the corresponding record of that in the "emp"table should be updated that is only the "status " column set to be OFF.

you can change the status while inseting the data in emp_detail table. Or you can create a triger on emp_detail table on insert and check the eligible column and update emp table as per value

This is a waste of time, it creates an image on the server. Generate an img tag which has a src attribute with the server path ( so not the file path, but the path as a URL that a browser can see )

If your ASP.NET app can see the file, then it must be within the web application. Sending c:\inetpub\MyApp\images\cgraus.jpg means nothing to the client. \images\cgraus/jpg will work fine, it's a path from the web root.

Hi,
I was wondering is there a way to create groups in session. so that if I needed to clear down session variables pertaining to a particualr section of our application, I could call Sesswion.Clear on that group, but leave all others intact?

Upto my knowledge NO.

You can do this using Arraylist or any other memory storage. So each of your section values are filled into ArrayList and store arraylist object to session. To remove a particular section data, simply do Session.Remove(your section name). So arraylist object contained in the specified location will be removed and others will still exist in the session.

Thanks for your help, much appreciated. I have decided to implement a Dictionary in order to create groups in session.
