In order to perform various actions over Syncfusion GridControl, you first need to locate the row that contains the data you are going to work with. This topic describes how you can search for the desired grid record.

The GridControl object does not have built-in methods for searching within the grid, so you will need to implement the search algorithm yourself. A general search approach implies that you iterate through the grid rows and on each iteration check whether the row meets the specified condition. For example, you can check if the cell text or value in a particular column is equal to the specified text or value. (To learn how you can get GridControl cell values and their display text, see Obtaining and Setting Cell Values in Syncfusion GridControl.)

The script below demonstrates how you can locate a particular row by iterating through the grid rows. It contains two sample functions named FindRow and FindRowByCellText, that search for the grid row by a cell’s value and text, respectively.
