View 6 RepliesI have an updatepanel with detailsview in it. Detailsview contains two template items, Country and State. In the readonly state, label is used to dispaly the values. In the Edit and Insert mode, dropdownlist is used. Objectdatasource is set as the datasource for dropdownlist. When the selectedindex changed for country dropdownlist, the corresponding states should be fetched. I have set a select parameter in state objectdatasource. I could not set controlparameter in state datasource as in the readonly mode, dropdownlist is not available. So, i used onselecting event of state datasource to set the value(i.e selectedvalue of the coutry). But what i observed is that seletiing event is not firing when a postback happens because of coutry selectedindex change. I found that post back is happening due to the event and country datasource is selecting, but it si not refreshing the state list.

View 5 RepliesI have an updatepanel with some textboxes and dropdownlists they have autopostback set to true. They are all defined as triggers on the updatepanel. I want the user to be able to change data in a textbox and tab to the next and have the text selected in each textbox he enters. My problem is I receive the first postback fine, make some database updates, then exit. The next textbox is not being selected, so I added thge final instruction in the data changed event to nexttextbox.focus. That seems to work, however the nexttextbox does not have the text selected. How can I do that?
View 2 RepliesThe CalendarExtender used with TextBox has a problem when you select previous years, months and a day in that the day reverts to "1" no matter what day of the month that you choose. Microsoft usually has a free patch for something like this when that happens.
If I am correct and there is a patch for this bug can anyone tell me where to find the patch and if there is no patch can anyone tell me how to solve this problem?
I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.
[code]....
I have a page that displays data depending upon the date range entered by the user into two textboxes. I have added the CalendarExtender control from the Ajax Toolbox to each of these two textboxes, and I would like the associated updatePanel to refresh with new data whenever either of the two dates is changed. Sounds simple enough, but I have not been able to manage it so far.
View 7 RepliesI am using HoverMenuExtender on a label LinkButton .The Popup control is a Panel, that contains a DropDownList with some listitems inserted in it. Everything is going well, when i hover over linkButton that Panel and along with that that DropDownList appears.
Now problem is that when i hover over list items of DropDown , suddenly that Panel disappears before selecting any value.Panel disappears means that DropDownList also disappears. One rubbish solution is to increase the popup delay time to 3-4 seconds.
This GridView contains a TemplateField with a LinkButton that displays a text value. When the link button is clicked, the code behind needs to capture the text value of the button, and then refresh the GridView with an asynchronous postback within the UpdatePanel and display the updated output.
The post-back event is occurring, and I'm able to capture the event in Visual Studio 2010 debugger. But, the screen contents do not change after this event occurs. No exception gets thrown, at least from what I can see in debugger.
Portions of the sanitized code appear below. The GridView actually appears on a page that contains 2 dropdown lists and 2 other GridViews. There is just one UpdatePanel on this page.

This is in the Code-Behind.

I can put a break point in the above method, and it is captured when the lnkHostName button is clicked. Stepping through the lnkHostName_Click() method, the ReloadPage() method successfully runs, then executes this method:
[Code]....
This runs successfully, and the DataSet which gets returned contains 1 row of data rather than several rows. This is what I expect to happen. Once the filter is selected in my test case just 1 row should get returned. The problem is that I don't see that output refreshed on the screen. The grdProcesses gridview continues to display the original dataset of several rows, rather than just one row of data. To additionally test this, I tried setting the visibility of grdProcesses to false within this method when the HostName had a value. Again, this ran without an error, but the GridView was still visible. And I also tested by updating the contents of a label with the HostName value. The new value was never displayed in the label. I also tried putting the lnkHostName button into the triggers, ala:
[Code]....
But the following exception gets thrown when that button is added, "A control with ID 'lnkHostName' could not be found for the trigger in UpdatePanel 'upMain'."
What's frustrating is that everything appears to run smoothly in debugger. But in reality the expected output never gets refreshed on the screen. Perhaps I need to use an alternate trigger in the AsyncPostBackTrigger. I'm open to using a command button or some other artifact.
I'm trying to find an ajax.net extender element with a dynamically generated ID. I'm trying to wire up an event handler to close all ajax.net modal popups when 'escape' is pressed. I'm confused why one of these works and one does not.
$find('ctl00_MainContent_ucUserControl1_mpePopup'); //returns the element
$find('[id="ctl00_MainContent_ucUserControl1_mpePopup"]'); //returns null
The ultimate goal is to be able to find the element without hard wiring the ID into the selector: $find('[id$="_mpePopup"]'); //return all elements that end with "_mpePopup"

And On Page Load i have done this to avoid selecting previoud dates in start date :

Start_CalendarExtender.StartDate = DateTime.Now;

Now i want to do that user cannot select end date less than start date , e.g if he choose 2-July-2014 ( as a start date) then he could not choose (1-July-2014) as End date , dates prior to Start Date must get disabled in End Date Calendar Extender.

I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.
I have problem with validators in update panel. Tried to look for solutions in google but failed to find working solution. So this is my code (simple login panel):

I am trying to verify if a username is taken or available by using jquery to send a request to an asp.net page. The ASP.net page is clearly getting the information as I am having it make an entry into a log database. My SQL server database indeed shows the username being passed to it and is returning a value however for some reason the client side html/javascript doesn't RESPOND to it. I am not sure if it is on the end of my html/javascript or perhaps my asp.net page is not returning the json information correctly? This is my first attempt at json The checking availability box shows up on the html page but it NEVER changes even when the sql server shows that it ran the stored procedure
