Hi Lars,

It seems like the MasterMain Id does not exist. Are you sure that:

• There is not a typo / you got the right Id?
• It has already been defined when you're requesting it?
• It is in the right hierarchy of blocks?
• Is this in the proper Custom__Blocks.cshtml file? (Context)

What does customMasterBlocksPage.GetBlocksStructure() return?

Best Regards,

Nuno Aguiar

When looping the list returned by:

customMasterBlocksPage.GetBlockListById("MasterMain").OrderBy(item => item.SortId).ToList()

I get these two id'es: "MasterHeader" and "MasterContentPage" as expected. So I don't think it's a typo.

I have also tried on a clean new Rapido where I inserted the code below into Designs\Rapido\MasterBlocks\Custom__Blocks.cshtml:

@inherits Dynamicweb.Rendering.RazorTemplateBase<Dynamicweb.Rendering.RazorTemplateModel<Dynamicweb.Rendering.Template>>
@using System
@using System.Web
@using System.Collections.Generic
@using Dynamicweb.Rapido.Blocks

@{
    BlocksPage customMasterBlocksPage = BlocksPage.GetBlockPage("Master");

    var newMasterMainBlock = new Block
    {
        Id = "MasterMain",
        Template = CustomRenderMasterMain(customMasterBlocksPage.GetBlockListById("MasterMain").OrderBy(item => item.SortId).ToList())
    };
    customMasterBlocksPage.ReplaceBlock(newMasterMainBlock);
}

@helper CustomRenderMasterMain(List<Block> subBlocks)
{
  <main class="myCustomClass site dw-mod">
    @RenderBlockList(subBlocks)
  </main>
}

And I get the exact same error.

Hi Lars

Can you try changing the Id like this?

var newMasterMainBlock = new Block
    {
        Id = "CustomMasterMain",
        Template = CustomRenderMasterMain(customMasterBlocksPage.GetBlockListById("MasterMain").OrderBy(item => item.SortId).ToList())
    };

Maybe "MasterMain" is already defined...

Hi Kim

If I change the id name from "MasterMain" to "CustomMasterMain" then I don't get the error. But the block "MasterMain" is not modified which must be because 

customMasterBlocksPage.ReplaceBlock(newMasterMainBlock);

does not replace the MasterMain block because now it's trying to replace a block with id "CustomMasterMain". It is exactly the block "MasterMain" I want to replace 

Bump

I need to add a class to the main or body tag in order to distinguish (on the client-side in the css) between two sites using the same Rapido design. Could I do something else than what I try above and which fails?
