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 RepliesThis 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.
[Code]....
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.
The 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 am using AjaxCalendar Toolkit :
<asp:TextBox CssClass="form-control" ReadOnly="true" runat="server" id="StartTime"></asp:TextBox> <asp:CalendarExtender ID="Start_CalendarExtender" runat="server" Enabled="True" TargetControlID="StartTime">
</asp:CalendarExtender>
<asp:TextBox CssClass="form-control" ReadOnly="true" runat="server" id="EndTime"></asp:TextBox> <asp:CalendarExtender ID="Start_CalendarExtender" runat="server" Enabled="True" TargetControlID="EndTime">
</asp:CalendarExtender>
And On Page Load i have done this to avoid selecting previoud dates in start date :
protected void Page_Load(object sender, EventArgs e)
{
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.
in my aspx page,
1. am using calendarextender bind with text box
2. button click event call th SQL stored procedure to save the form values
3. after save and get the output value from the SQL SP ( its boolean value)
4. if true i have to show the javascript alert or else nothing have to alert, so this is the code
if (CheckandBooked())
{
ScriptManager.RegisterClientScriptBlock(btnBook, typeof(string), "alertscript", "alert('Selected time period clashes with existing booking');", true);
}
bug: this is working good but while showing the alert time i can see the calender( it look like design view) the design is adjusted how to avoid this
Here is the setup:
VS 2008Update PanelIn the update panel, is a gridview, and an asp:panel that contains some other controls, including the button I want to trigger the update of the gridviewThe gridview is tied to a sqldatasource, although I have tried multiple methods to get the data and all failed
Here is the problem:
User logs in and fills out the top part of the form. That submits some data to a table, returns the ID of the row submitted and makes an asp:panel visible (panel.visible=true). This update panel exists inside of the UpdatePanel. The user clicks a drop down list and selects a name. When this happens, another panel becomes visible, using the same process, to allow the user to enter data about the name they selected. So far, everything works.
What Should Happen next:
User clicks "Add" buttonDatabase is updated with the data enteredDatasource refreshesGridview refreshes - It is not visible at load because there are no records for it to show.
What Actually Happens:
User clicks "Add" button Database is updated with the data entered - This has been verified Datasource should update, but not sure it is Gridview does not show.
Here is the code snippet for the Update Panel:

Everything is working great, except during one of the PostBack from within the UpdatePanel, I want to refresh the tree. This just does not seem to be possible.
Is there a way to set a maximum of a CalendarExtender? Like it can't go farther than '2079-06-06' (This is the limit ouf SqlServer SMALLDATETIME). Or the only way to block the user from entering a date that is out of range is to verify manually?
View 2 RepliesI have read many forums to see if I could find a solution and there hasn't been anything that is what I need. I have an asp:calendar that you select a date on there and a panel pops up. On the panel, the start date and end date are filled with the selected date from the asp:calendar. The end date field has the CalendarExtender. When you open it, the selected date on there is the same as from the asp:calendar which is good. What I need is to tweak my javascript to check to make sure that the user picks a date after the selected date from the asp:calendar. so if they pick 11/4/2010 as a start date, the end date cannot be fore 11/4/2010. Only anything after that. Not todays date(ex. 10/22/2010).codebehind for my asp:calendar sending the dates

I must be missing something here. I use the code below to display a DateTime value, and the time is always displaying, i.e. 7/11/2010 08:10:10.
I just want the date. The Format value doesn't seem to have any effect.
<asp:TemplateField
HeaderText="Exp Date"
HeaderStyle-Width="100px">
<ItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
Text='<%# Bind("expirationDate") %>'></asp:TextBox>
<cc1:CalendarExtender
ID="CalendarExtender1"
runat="server"
TargetControlID="TextBox1"
Format="MM/dd/yy"
/>
</ItemTemplate>
</asp:TemplateField>
I have a calendar extender tied to a textbox. When I select a date from the calendar, it displays the selected date in the textbox. When I click a submit button, it passes no value. why the textbox doesn't store the value from the calendar?
[Code]....
[Code]....
I need to display dates as "dd/MM/yyyy"
The Format property of the CalendarExtender doesn't work when the EnableScriptGlobalization and EnableScriptLocalization properties of the ToolScriptManager are True. For some unexplicable reason the seperators are changed from "/" to "-"
I can get around this problem on the client by formatting the bound textbox in the OnClientDateSelectionChanged client event but have no way to set the CalendarExtender SelectedDate property on the server because the wrong date seperator is displayed.
What I'm finding is that if I externally change the date in the text box that the CalendarExtender is attached to (I'm also using an image button with a calendar image to invoke the calendar - like the last example on the
samples page), the date on the calendar does not stay in sync.
Example:
page loads. text and calendar are set to 1/14/2010. cool. on the click event of a button elsewhere on the page I set the date in the text box to 12/15/2009.
I would expect that clicking on the calendar button to display the calendar would show December 15, 2009 in the calendar, but instead it's still stuck on January 14, 2010.
What's involved in programattically setting the date in the CalendarExtender control
in javascript?
Is it possible to pick both the date and time with an ajax calendar extender? If so, how? If not any ideas are welcome in getting both the date and time into a datetime field of a textbox.
View 2 RepliesI want to change the formate of ajaxcalender extender like 23-Apr-2013 how it possible.
I want this because i have some rocrds in table where date is stored in formate of 23-Apr-13 and when i wnat to search it on basis of date i am unable to find it because may calender formate is 23-04-13. if their is no way to cahge the formate calaender extender so i convert 23-04-13 values to 23-Apr-13 using code ?
The below code is not working properly. It is showing always 08/08/2012 12:00:00 AM

I 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 1 RepliesI've got a TextBox with AutoPostBack="true" and OnTextChanged property set.
The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.
Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.
Here's how the thing looks:
[Code]....
Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.

I am working on a .NET web application and I'm trying to use ajax CalendarExtender for the users to specify a specific date. For some reason, when I click the icon to display the calendar, the background seems to be transparent, shown below:
What could be the reason for this?
I've tried googling it but it seems nobody has worked it out yet.
I've also tried setting up it's z-index property to as high value as 5000000 but still doesn't work.
