Yes, for this you have to use datatable and after inserting the first row in datatable u have to bind that datatable to the grid and next time , first u have to add the row in datatable and next bind it to datagrid. keep on doing.
u have to maintain the datatable state.
In older versions of TOAD, the grid is limited to adding/modifying CLOB's for existing records. This should be working in TOAD 7.6. Note, however, that since TOAD does not support Unicode databases, that there are often errors when viewing CLOB data in the data grids for databases with Unicode character sets.
To copy one row of data, put your cursor in a cell in the grid and press Ctrl+Insert. This will copy the row and its column headers to the clipboard. To copy multiple rows of data, right-click in the grid and choose "Allow multiselect". Use Shift-Click to select multiple adjacent rows, or use Ctrl+Click to select individual, non-adjacent rows. Press Ctrl+C. This will copy all of the rows and their column headers to the clipboard. To copy a single cell's data, turn off "Allow multiselect". Click on the cell you want to copy and press Ctrl+C.
The following table gives details of what happens with the various copy keys and multi-select options.
Multi-Select OFF Multi-Select ON
EDIT COPY CTRL+C CTRL+INS EDIT COPY CTRL+C CTRL+INS
One Cell Highlighted Cell only Cell only Row plus headings Cell only Cell Only Row plus headings
Many Cells(rows) highlighted N/A N/A N/A All highlighted rows plus headings All highlighted rows plus headings All highlighted rows plus headings
Reset NLS_LANG on your Client machine to AMERICAN_AMERICA.JA16SJIS to view Japanese and AMERICAN_AMERICA.ZHT16BIG5 to view Chinese. Then change the font script for each language by right clicking on the data and choosing Grid Options | Data Grids - Visual | Fonts | Grid and choose Arial Unicode MS as the Font. This changes the script to Japanese for Japanese characters or to ChineseBig5 for Chinese.
using template column we can very well add date time control as child contorl
For refreshing data in data grid control we can use chasing technique

If you want to customize the content of a column, make the column a template column. Template columns work like item templates in the DataList or Repeater control, except that you are defining the layout of a column rather than a row.
You cannot specify formatting for columns generated when the grid's AutoGenerateColumns property is set to true, only for bound or template columns. To format, set the column's DataFormatString property to a string-formatting expression suitable for the data type of the data you are formatting.
