I have at text box with a validator control which works fine (prevents letters being entered, only numbers)
However once it displays the error message I am unable to do anything else on the page, links don't work etc. I have to close down the window and start the website agin.
I have an issue that I've been fighting with for some time. I have a large web form, with update panels and autopostback controls. When the users click "submit", some custom javascript runs which shows validation summaries and turns the fields with errors red, relatively easy, and it works as expected. The problem is that I have a dropdownlist which should autopostback an update panel. It does this perfectly if the user does not click the submit button, and therefore my custom client script dosesn't execute.However, if a user clicks submit, the custom client script executes (turns fields red and shows validation summaries), and then the dropdownlist does NOT autopostback the first time a user changes it's value. If the user changes the dropdownlist's value a second time, then the autopost back occurs and everything functions as it should. I don't understand why the autopostback is disabled for the first click after the javascript executes. Can someone please help me out? The DropDown List looks like:

The Submit button is:

How can we use required field validator on User Control in aspx page*strong text*
I have one user control that have one drop down. I am using this control on my page. I want to use required field validator on this drop down.
there is a sample code for creating a custom textbox control with built in validation posted here Building ASP.NET TextBox with Integrated Validation And Switchable Input Modes. Inside the code there is a call to Controls.Add(validator) which adds the asp.net validator control to the textbox. when the textbox is used on the page, the validator is rendered to the page although the validator is added to the textbox and not to the page!
View 1 RepliesI have a situation where in, one of the form has to show some processing message on the Page and then automatically redirect to another page.
View 5 RepliesI have an autopostback dropdown with a requiredfieldvalidator associated with it. If I click the submit button on the page without selecting an item from the dropdown, the validator will fire as expected. Then, if I select an item from the dropdown, the validator message goes away, but the postback does not occur. The postback only works if the validator has not fired first.Is this by design? How can I work around this so that the dropdown still does a postback when selecting an item after validator occurs?

I was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

View 1 RepliesI am able to route my urls to an existing page. Here is how our scenario is currently working:
On Default.aspx, we have several links that link to pdf files on the server. The filenames of these files change dynamically which is why we need the url routing. When the user clicks on of the urls, the link is routed to the getFile.aspx page that has logic in it to determine which file to open.
Is there a way to have the getFile.aspx page to open in the same window as the default.aspx page?
Otherwise, I need for the getFile.aspx page to close after the intended processing is complete, and I've not been able to close it without getting the close window dialog box. I figure if it opens in the same browser window, I can redirect back to the default.aspx page when processing is finished.
I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.
View 1 RepliesI'm using the following code to iterate through a list of validators on the page. For each validator, I want to set the background color for the control its responsible for validating. The problem I'm having is that FindControl method is always returning null. From searching the web, it appears the problem is that the page has a master page. Whether this is the issue or not, it's obvious that the FindControl method cannot find the ControlToValidate control.
Method used to iterate all validators on a page:
protected void ShowControlsToValidate(Page page)
{
if (page == null)
return;

We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?
View 2 RepliesThe following code works fine for disabling content page controls, but how do I disable master page controls?
public void DisableControls(Control control,bool isEnable)
{
if (control.HasControls())
{
foreach (Control c in control.Controls)
{
DisableControls(c, isEnable);
}
}
else
{
if (control is IPostBackDataHandler && !(control is IPostBackEventHandler))
{
if (control is WebControl)
{
((WebControl)control).Enabled = isEnable;
}
else if (control is HtmlControl)
{
((HtmlControl)control).Disabled = !isEnable;
}
}
}
}

View 2 RepliesI have more than two text boxes in my web form.Now I want to validate either of the text boxes value is empty then only user should get error message i.e enter either text values.
For ex: There are two text boxes Phone no and Name. If user clicks on submit button without entering in either of text boxes then only user will get error message i.e enter either phone no. or your name .I can use the javacript in order to solve this case but I want to know is there any control in asp.net to solve this purpose?
I have a a web form with multiple formviews and one field is a mandatory field. Each formview has its own submit button. User cannot submit the data in any of the formviews until that one mandatory text field is entered.
But I also have another section in the webform, which has a calculation code in it. It takes in input from two text boxes, does some calculations and displays the result in another text box. Because of the validator control, I am not able to run the calculation code without the mandatory field filled in. I would like to run the calculation code irrespective of the mandatory field.
How do I do this? I need that submit button (in calculation section) to disregard the validator and display the result.
I am adding validator controls to a page on runtime. When I do this it seems to work except for one thing: the page doesn't get validated (the Validate() method is not invoked) - neither on the client nor on the server. However when I can Validate() myself, the validators do their work and generate the required errors. So it looks like the simple fact of adding a validator programmatically causes the page validation to not take place. My page does have validators in the aspx file - they work fine when I don't add any programatically, but as soon as I do add one programatically, the Validate() method is not invoked.
The way I add the validators is by creating an instance, giving values to all relevant properties, and then adding to the page control collection. I tried this in the PageLoad, and prior page-cycle events. The same result occured. I also tried with or without having a ValidationGroup, and with or without having a ValidationSummary control on the page. The same result occured.

I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
