### Description

Gets or sets a [DataTableInfo](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/datatableinfo/llms-full.txt) object representing the table which is used as a master table when merging data into the document. Changing the master table with this property influences the return values of the [PossibleMergeBlockTables](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/datasourcemanager/possiblemergeblocktables-property/llms-full.txt) and the [PossibleMergeFieldColumns](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-datasources/datasourcemanager/possiblemergefieldcolumns-property/llms-full.txt) properties.

### Syntax

```csharp
public DataTableInfo MasterDataTableInfo { get; set; }
```

```vbnet
Public Property MasterDataTableInfo As DataTableInfo
```

### Examples

The following example reads the current master data table info value without replacing the SDK-supplied object. The created object is then available to the surrounding document workflow.

```csharp
Console.WriteLine($"Master Data Table Info: {dataSourceManager.MasterDataTableInfo}");
Console.WriteLine("Data Source Manager is ready for use.");
```

```vbnet
Console.WriteLine($"Master Data Table Info: {dataSourceManager.MasterDataTableInfo}")
Console.WriteLine("Data Source Manager is ready for use.")
```
