I am creating a mobile website using radcomboboxes inside of update controls that are set to autopostback = true. All of the controls work except on the page's initial load the UI elements are enlarged and look more like buttons. They are still able to be selected and after the controls postback the elements still do not go back to a normal size. Only after a postback from another control do the UI elements shrink down to a normal size.
I have tested the radcombobox with checkboxes enabled outside of the update panel and this behavior does not change. I have a master page that contains jQuery files located in the header, and when I remove one of the js files, the problem disappears with the UI elements disappearing. Can anyone help me figure out what is preventing the UI elements from rendering properly?
On Load:
After postback:
Hi Erica,
It seems like you are experiencing a conflict between the jQuery JavaScript file and the Telerik RadComboBox controls within the UpdatePanel. This kind of issue is common when using multiple libraries or controls that manipulate the DOM, as they might have conflicting styles or scripts.
Here are some troubleshooting and debugging Steps to try:
Console Errors: Open the browser's Developer Tools (usually F12) and check the Console tab for any errors or warnings. This can give you insights into any conflicts or issues.
Inspect Element: Use the Inspect Element tool to review the applied styles to the RadComboBoxes. Check if any styles are being overridden.
Network Tab: Check the Network tab in Developer Tools to see if all resources are being loaded correctly, and there are no 404 or other errors.
CSS Conflict: Review the applied CSS to see if there are any conflicting styles that might be affecting the rendering of the controls.
Change the render mode of RadCombobox: Test with different render modes: https://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/rendermodes/defaultcs.aspx.
Avoid mix of different render modes - Make sure that all Telerik components on the page have the same render mode - https://docs.telerik.com/devtools/aspnet-ajax/styling/controlling-visual-appearance/render-modes and https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/controls-appearance-incorrect-or-distorted.
Try the Latest version: Upgrade to the latest Telerik.Web.UI.dll version and see if the problem still persists.
Isolate the Issue: Try to isolate the issue by creating a minimal reproduction of the problem. Start with a basic page with only the necessary elements and scripts, and gradually add more elements to see when the problem occurs.
