PreselectedItemUrl incombination with FileExplorer paging

[Fit2Page]

In my Standalone Image manager I encounter the following: When using StandAlone.AdditionalQueryString = "&PreselectedItemUrl=xxxxxxxx" in combination with File Explorer paging the correct image is not selected. Is there any workaround for this?

 

Thanks,

Hi Marc,

The PreselectedItemUrl is a QueryString parameter that should be added to the DialogOpener using its set_additionalQueryString() client-side method,e.g.:

<script type="text/javascript">
    var oldAdditionalQueryString = null;  
    function OpenImgManager() {
        var dialogOpener = $find('<%= DialogOpener1.ClientID %>');
        var args = new Telerik.Web.UI.EditorCommandEventArgs("ImageManager", null, document.createElement("img"));
        var txt = $get('<%= TextBox1.ClientID %>');
        
        var itemUrl = "/Images/animal.png"; //path to the image


       
        //add an if check if the txt box is empty set the default itemUrl from above, otherwise set the new textbox value by extracting the src path from the img tag
        if (txt.value != "") {
            var imgTag = txt.value;
            // Extract src value using regex
            var match = imgTag.match(/src=['"]?([^'"]+)['"]?/i);
            if (match && match[1]) {
                var src = match[1];
                // Remove domain if present
                if (src.indexOf(window.location.origin) === 0) {
                    src = src.substring(window.location.origin.length);
                }
                // Ensure it starts with /
                if (src.charAt(0) !== "/") {
                    src = "/" + src;
                }
                itemUrl = src;
            }
        }
        var currentQueryString = dialogOpener.get_additionalQueryString();//get predefined query string
        oldAdditionalQueryString = currentQueryString;
        dialogOpener.set_additionalQueryString(currentQueryString + "&PreselectedItemUrl=" + itemUrl);//add the PreselectedITemUrl parameter
        args.CssClasses = [];
 
        dialogOpener.open('ImageManager', args);
        dialogOpener.set_additionalQueryString(currentQueryString + "&PreselectedItemUrl=" + itemUrl);//add the PreselectedITemUrl parameter
        dialogOpener.set_additionalQueryString(oldAdditionalQueryString);
        oldAdditionalQueryString = null;  
    }
 
    function ImageManagerFunction(sender, args) {
        if (!args) {
            alert('No file was selected!');
            return false;
        }
 
        var path = args.get_value()[0].src;
        var txt = $get('<%= TextBox1.ClientID %>');
        txt.value = "<img src='" + path + "' />";
    }
</script>
 
<asp:TextBox runat="server" ID="TextBox1" Width="400px"></asp:TextBox><br />
<telerik:DialogOpener RenderMode="Lightweight" runat="server" ID="DialogOpener1"></telerik:DialogOpener>
<button onclick="OpenImgManager();return false;">Open ImageManager</button>

I tested this solution and verified that it works as expected in a paging scenario with multiple pages and files.

Thank you for your reaction, Rumen.

It appears now that the problem we had was due to the fact that the value of the PreselectedItemUrl parameter is case-sensitive. As IIS and Windows folder system are not case-sensitive, shouldn't this be re-factored?

Thank you for the follow-up and for identifying the cause of the issue.


You're absolutely right - the case sensitivity of the PreselectedItemUrl parameter can lead to unexpected behavior, especially given that IIS and the Windows file system are not case-sensitive by default. This inconsistency could indeed be confusing.

As a workaround, I'd suggest normalizing the casing of the URLs used in the PreselectedItemUrl parameter to ensure consistency with how the paths are stored or returned in your application.
