## In This Section

- [MergeBlockInfo.Apply Method](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/apply-method/llms.txt): Stores the meta data (filters, sorting instructions and the block merging condition) in the SubTextPart which represents the block. Manipulating any of the aforementioned collections does not update the block automatically, so this method must be called to actually store changes. If a MergeBlockInfo instance is not based on an existing SubTextPart, this method throws an exception.
- [MergeBlockInfo.BlockMergingCondition Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/blockmergingcondition-property/llms.txt): Gets or sets a condition the parent data row of this merge block has to satisfy so that this merge block is merged at all. To keep the merge block independent of a condition just leave this property at the default value null.
- [MergeBlockInfo.ChildBlocks Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/childblocks-property/llms.txt): Gets or sets the list of merge blocks nested inside this merge block.
- [MergeBlockInfo.ColumnNames Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/columnnames-property/llms.txt): Gets or sets the list of data column names which represent the merge fields this merge block consists of.
- [MergeBlockInfo Constructor](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/constructor/llms.txt): Initializes a new instance of the MergeBlockInfo class.
- [MergeBlockInfo.Filters Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/filters-property/llms.txt): Gets or sets a list of filter instructions which are used to filter the data rows before merging. To not filter the block data, just leave this property empty or set it to null.
- [MergeBlockInfo.MergeFields Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/mergefields-property/llms.txt): Returns the merge fields inside this merge block excluding fields in possible nested merge blocks.
- [MergeBlockInfo.SortingInstructions Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/sortinginstructions-property/llms.txt): Gets or sets a list of sorting instructions which are used to sort the data rows before merging. To not sort the block data, just leave this property empty or set it to null.
- [MergeBlockInfo.TableName Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/mergeblockinfo/tablename-property/llms.txt): Gets the table name of this merge block.
