Web Forms :: Bind RequiredFieldValidation To Buttonclick?
Oct 19, 2010
I have a form for registering customers, with RequiredFieldValidations that each are bound to a specific textbox. My problem is that I would also like to bind them to one specific buttonclick, since I have other buttons which I don't want to trigger the validations. Is that possible?
I am putting a C# asp.net web form together that has a number of fields that we want to ensure data is inputted in them. I have added the RequiredFieldValidation control, but I am unsure what to put in the Button_Click event. I want the click event to check the fields and if not filled in, preserve the fields that already have data and then return the page data with the missing fields so that they user can take corrective action.
I have a page with 1 RequiredFieldValidation control on it. This same page also displays a popup. The popup has a linkbutton on it. When the link button is clicked the validation control displays that a value is required on the underlying page. To be clear the validation control does not display on the popup. It displays on the page where it belongs.
It seems that I would need to disable the validation control when displaying the popup.
if i click a button and i have a string(2010/08/12,2010/08/13,2010/08/14,) in the textbox it divides to 2010/08/14 in the textbox wich i dont want here is my code
I have trouble with the sequence of events on my page. I have a button, which on its onClick event calls a method, which posts data to a database, and causes a postback. But on the same page I have a repeater which uses the data that is being modified by the button. I would need somehow the buttonclick event occur "earlier" than the databinding in the repeater to show the correct data.
I need to open a new window or page keeping the existing page open. I plan to put a Button on the existing page and when a user click the button, a new page or window pops up with what I have coded for that page. My preference would be that the user don't have to tweek any browser options or configure anhing else to open the new window with the click.
This is my code for datagrid with Htmlinputfile control.Datagrid opens in modalpopup created in javascript.On button click i am trying to submit values of Htmlinputfile.But it becomes null.I dont know how.
On Page load i bind user controls UC1, UC2 with selected value of radiobutton. But when i select new value in radiobutton it fires selectionchanged event, executes bind method but doesn't update uc1,uc2 values. Similarly I'm trying to get button commandargument when button is clicked and update usercontrols but it doesn't.
What could be causing them not to update even when bind method is executed?

Basically I was wondering if there is a method of binding a datasource to a contentplaceholder, I want to display data within a contentplaceholder from a database, however as I can't insert a control into a contentplaceholder, I have nothing to bind/display the data. The information within the database includes html for presentation, therefore I just need to get it out. Also the master page will only be supplying one page with data, so doing this within the master page would also be a solution.
I need to bind data from an SQL Select Statement into a RadioButtonList and have not been able to come up with anything that works.
