Large Excel Files Fail to Post to Proxy

Environment

Product

Progress® Kendo UI® Grid for jQuery

Description

I use a proxyURL and forceProxy properties to send all the generated workbooks to the server to improve performance. This works for smaller data sets without issue. However, on large data sets the POST is triggered to go back to the server, but it never reaches the server. Something dies there and the Save() method on the Controller is never called.

Solution

This particular problem is related with limitations not related with the Grid, but rather to the IIS and the application. Nevertheless, you could try increasing the maxAllowedContentLength and the maxRequestLength:

    <system.webServer>
        <security>
            <requestFiltering><requestLimits maxAllowedContentLength="524288000"/>
        </security>
    </system.webServer>

    <system.web>
      <httpRuntime maxRequestLength="524288" executionTimeout="120" />
    </system.web>
