AJAX :: Validator Callout Issue In Listview Control?
Mar 10, 2010
Today i faced a new issue in Listview control the issue is i have insertitemtemplate in my listviewcontrol and i have a textbox control,Required FieldValidator and ValidatorCallout control in that template. The issue is the validation fires but validator callout dosent come next to the control its coming in the center of the Listview. so can any 1 please help me on that.I have a master page and the page is as a content page.
For some reaon the black outline isn't appearing around my Validator Callout Extender's callout box. I don't have a css class set. It should display a yellow callout with a black outline. Like on the sample page:
[URL]
It shows the yellow call out with the black outline around the pointed part but not the main box.
I've got the validator callout on my site and I've not been able to figure out how to style it. I don't want anything fancy- just want to change the background colour and text colour.
I wan to do a required field validation for the cascading dropdownlist . When my page first load out the validator is fired first in the google chrome, the callout extender message is prompt out first in the Google Chrome. I have tested the code in IE and safari, this two browsers never prompt out the validator callout first when the page is loaded.
i wonder why the google chrome will prompt out the validator when i validate the cascading dropdownlist. I have did some research on it, but failed to get any solution.
The Validator Callout Extender used to stretch the document wider if it was attached to the right side of an HTML element that was near the right edge of the document.At some point in the recent past, this behavior was modified to cause the popout to move to the left side of the html element, but the popout still points to its left.This behavior can be seen by going to the demo pages, narrowing the window to just beyond the page width, and then causing the second html input's validation to fail.I would like to know how to force the callout extender to the right-hand-side like it used to do, or have it automatically redraw itself as a left-hand popout if it jumps to the other side.
I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.
I'm just getting started with MVC and wanted to see how I can implement something that resembles the ValidatorCallout in Ajax Control Toolkit. The unobstrusive validator is pretty good but in some cases I really like the call out approach -- seems to get user's attention a bit more aggressively. how to implement that in MVC3.
now the task is to show a popup window, much like the standard Windows login panel, to warn the user that caps lock is on. I've used a ValidatorCalloutExtender alongside other controls in my site, but can't figure out how to use the test for whether the capslock is on:
[Code]....
to then show a callout style display. I'd prefer it only pop up when the user enter's the asp:textbox control, but can't figure out if a callout is possible in this way.
I have a textbox control that I need to limit the value entered into it, so used the RangeValidator control, and added the extender to show the error.This is my code, and for years 0 to 5, and 10 and above it gives no error (as expected) but for 4,5,6,7,8 and 9 I get the callout extender displaying! I can't see what I have done wrong, or is this a bug/issue with one/both of the controls? The only work around to use is to set it to 05, 06 etc, but this is not ideal.
[Code]....
The version of the toolkit dll i am using is for 3.5, so 3.0.30930.28736.
After the validators were put into a table, their appearance was completely messed up. The worst is the disappearance of the background. The background has been restored by setting a default skin for all ValidatorCalloutExtenders, but now they are just simple rectangles containing the exclamation mark and the error message adjacent to the target control. The callout look is gone.
i am using a content editor (WYSIWYGEditor) which provide by innova studio.I wonder how can i use a ajax control validator to validate it when it is empty value in the editor.
<asp:RequiredFieldValidator ValidationGroup="vgAlbumSetting" Display="None" runat="server" SetFocusOnError="true" ID="rfvPhotoPerRow" ControlToValidate="txtPhotoPerRow" ErrorMessage="<b>Required Field Missing</b><br />Total photo per row is required." />[code]....
how can i use a requiredfield validator to validate when it is empty value? i dont wish to use the backend code to do validation coz it will refresh the page.
I have several buttons on a page, but have assigned some validators and AJAX validator callout extenders to one button in particular. However, the validator callout extenders seem to be firing even if I press a different button. I thought this was the point of setting a TargetControlID (for the valiator callout extender) and a ControlToValidate for the validator itself!
I have a popup which displays two drop down lists, name it : ddl1 and ddl2 and for both of these i have mandatory validation, so if any of these is not provided, callout message will come on submit click.
ddl2 will get populated once any value from ddl1 is selected(selected change event).
Now problem is, suppose without entering any value, i click submit, it is showing select value for ddl1, and when i select a value, the selected change event for ddl1 is not firing, and so ddl2 is not getting loaded.
Selected change event for ddl1 is firing in normal condition, if the callout message is not there.
but after the callout message, if i try to select a value, the event is not firing.
I am trying to set the width property of a custom control validator but it is not happening at all. The width of the validator control popup is constantly 100% width (the width="200px" below has NO effect at all)
I am having a listview control in my aspx page with name "vehicleListView" and i am assigning the datasource from js function. But when i took the listview control by using the following line
document.getElementById("VehicleListView"),
I am always getting "undefined"
Ho can i get the listview control id in javascript function.Listview control is in an update panel.
I have to assign the datasource of the listview control from js only.Because the jd function is getting the datatable from the C# pagemethod.
With respect to my previous questionListview Checkbox checked using jquery . The code works fine and it checks for any checkbox checked in listview and returns a alert msg but now it does not check for any required field validators in the page. I the checkbox is checked it fires button click event. I need to check for validators also and after that only it must check for checkbox validation. The link for previous question is [URL] .....
I need to merge the code for required field validation check with checkbox check.
I have a web form with a modalpopupextender and a listView control that opens for editing and adding records. One of the columns on the listview is a linkbutton that makes a serve side call to show the modaldialpopupextender. At first, when clicking on the linkbutton in the listview the modalpopup displays over the listview, the page fades (via a CSS class) and it works great. When I open and close the listview for editing or change pages on the listview, and then try to show the modalpopup via the linkbutton, the modalpopup displays under the listview and the fading does not work properly. I am not too sure if this is a postback/javascript issue or maybe CSS?
I have a CheckBox that is located inside a SelectItem Template. The CheckBox has Autopostback= true. Located outside the list view is a label. When the CheckBox is checked, I would like to trigger an the Updatepannel that includes the label. Instead I get an error message "'CheckBox1' could not be found for the trigger in UpdatePanel 'UpdatePanel3'. The code snippet is as follows:
