Syntax
public static class TreeGridIndexResolver : ObjectMethods
GetHeaderIndex(SfTreeGrid)
Gets the zero-based index of the last header row in the specified tree grid.
Declaration
public static int GetHeaderIndex(this SfTreeGrid treeGrid)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The tree grid from which to retrieve the header index. Can be null. |
Returns
| Type | Description |
|---|---|
| System.Int32 | The zero-based index of the last header row if |
GetNodeAtRowIndex(SfTreeGrid, Int32)
Gets the node at the specified row index.
Declaration
public static TreeNode GetNodeAtRowIndex(this SfTreeGrid treeGrid, int rowIndex)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The SfTreeGrid. |
| System.Int32 | rowIndex | The specified row index. |
Returns
| Type |
|---|
| TreeNode |
ResolveToGridVisibleColumnIndex(SfTreeGrid, Int32)
Resolves the zero-based grid-visible column index of the specified column index within the tree grid.
Declaration
public static int ResolveToGridVisibleColumnIndex(this SfTreeGrid treeGrid, int columnIndex)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The tree grid in which to locate the column. If null, the method returns 0. |
| System.Int32 | columnIndex | The specified column index. |
Returns
| Type | Description |
|---|---|
| System.Int32 | The zero-based grid-visible column index of the specified column; or 0 if the tree grid is null. |
ResolveToNodeIndex(SfTreeGrid, Int32)
Resolves the node index corresponding to the specified row index.
Declaration
public static int ResolveToNodeIndex(this SfTreeGrid treeGrid, int rowindex)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The SfTreeGrid. |
| System.Int32 | rowindex | The corresponding row index. |
Returns
| Type | Description |
|---|---|
| System.Int32 | Returns the node index of the specified row index. |
ResolveToRowIndex(SfTreeGrid, TreeNode)
Resolves the zero-based row index of the specified node within the tree grid, including any header rows.
Declaration
public static int ResolveToRowIndex(this SfTreeGrid treeGrid, TreeNode node)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The tree grid in which to locate the node. If null, the method returns -1. |
| TreeNode | node | The node whose row index is to be determined. |
Returns
| Type | Description |
|---|---|
| System.Int32 | The zero-based row index of the specified node, including header rows; or -1 if the node is not found or if the tree grid is null. |
Remarks
The returned index accounts for the number of header lines in the tree grid. Use this method to map a node to its corresponding row index as displayed in the grid, including headers.
ResolveToRowIndex(SfTreeGrid, Int32)
Resolves the zero-based row index of the specified node index within the tree grid, including any header rows.
Declaration
public static int ResolveToRowIndex(this SfTreeGrid treeGrid, int nodeIndex)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The tree grid in which to locate the node. If null, the method returns -1. |
| System.Int32 | nodeIndex | The specified node index. |
Returns
| Type | Description |
|---|---|
| System.Int32 | The zero-based row index of the specified node, including header rows; or -1 if the node is not found or if the tree grid is null. |
ResolveToRowIndex(SfTreeGrid, Object)
Resolves the row index corresponding to the specified data.
Declaration
public static int ResolveToRowIndex(this SfTreeGrid treeGrid, object data)Parameters
| Type | Name | Description |
|---|---|---|
| SfTreeGrid | treeGrid | The SfTreeGrid. |
| System.Object | data | Specifies the data to get its corresponding row index. |
Returns
| Type | Description |
|---|---|
