Use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Getting below error during creation of case :

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

    Use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
    Microsoft is claiming this bug as a feature, so it's up to us implementers to apply the community-designed fix to make this area of the product usable.  The post by capoTincho appears to be cut off (did the forums migrate?), so I wanted to post a more complete solution here.
     
    The problem can occur when a field's Basic Forum Metadata has the Control Style set to "Render Lookup as Dropdown".  Custom filtering can load records into the dropdown which are not visible in the first 5000 records of the view associated with the field, and selecting from them will result in the error "Invalid postback or callback argument."  The way to fix this is to copy the code from the Control Style "Render Lookup as Dropdown", then remove this style from config and replace the default style lookup using JS on load.
     
    We can implement custom filtering on the dropdown like this:
    (function ($) {
    $(document).ready(function () {
        // Code for custom filtering goes here
    });
}(jQuery));
    When we set Control Style "Render Lookup as Dropdown", the page renders a div.control containing a select and input tag, like this:
    <div class="control">
    <select></select>
    <input>
</div>
    While using this Control Style, copy the select and input tags and save them for use in the JS.
     
    Next, set the Control Style to null.  This will render a lookup field in the default style, like this:
    <div class="control">
    <div class="input-group"></div>
    <div class="lookup-modal"></div>
</div>
    In the JS, we just need to empty out this div.control and append the tags that we copied when using "Render Lookup as Dropdown".  This needs to happen before any custom filtering code, like this:
    var lookupParentControl = $("#new_mylookupfield").parent().parent();
lookupParentControl.empty();
lookupParentControl.append("<select ...></select>");
lookupParentControl.append("<input ...>");
// Code for custom filtering goes here
    Now the control will be unbound by the view's 5000 record limitation, thereby avoiding the error "Invalid postback or callback argument."

    Yes,

    We also did same kind of thing.

    1) Hide the lookup field

    2) Create our custom control

    3) And on change of that custom control, store the value in original lookup.

    This how I bypassed this error. Firstly, I removed the metadata that renders this lookup as a drop-down. Then, in the custom JavaScript I added this code to 'force' lookup field render as a drop-down but without the metadata:

    //Hide lookup control and save it into a variable
$("#{lookupLogicalName}").parent().parent().hide();
var c = $("#{lookupLogicalName}").parent().parent().parent();

//Append a select tag with the following parameters to the above lookup  
$("

    Nicolai - did you ever hear anything from Microsoft or find a fix?

    Hi Nicolas,

    I came to the conclusion that this is a limitation of lookup fields rendered as dropdowns in the portal.

    The dropdown list will only show the first 5000 records.

    So if you have 7500 records in the entity you are looking up, and you filter the list to only show 7. If the one you then select from the 7, is not part of the first 5000 in the original list you will get the above error.

    I created a case for Microsoft on this issue, and they say that this is by design.

    Best Regards,

    Nicolai

    Did anyone come with a solution for this issue? I have exact same issue, have a JS that filters a lookup rendered as a dropdown.

    If I select some of the records from the dropdown I get exact same error as describe above, for others I don't get any error.

    How to stop the error?
