How to get GridView cell value in C#?

The GridView control in C# is a powerful tool for displaying and manipulating tabular data. It allows you to bind data from a data source and display it in a customizable grid structure. When working with GridView, you may often need to access the individual cell values for further processing or manipulation. In this article, we will explore different ways to get cell values in a GridView using C#.

Using GridView SelectedIndexChanged event

One way to retrieve cell values from a GridView is by handling the SelectedIndexChanged event. This event is fired when the user selects a row in the GridView. Here’s an example:

“`csharp
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
int selectedRowIndex = GridView1.SelectedIndex;
GridViewRow row = GridView1.Rows[selectedRowIndex];
string cellValue = row.Cells[0].Text; // Assuming the desired cell is at index 0
// Process the cell value
}
“`

In the above code snippet, we handle the SelectedIndexChanged event of the GridView. We obtain the index of the selected row using the SelectedIndex property. Then, we access the GridViewRow object corresponding to the selected row using the Rows collection and the selectedRowIndex. Finally, we retrieve the desired cell value by accessing the Text property of the respective cell using the Cells collection and the desired cell index.

How to get GridView cell value in C#?

The most direct way to get the value of a specific cell in a GridView is by accessing the Text property of the corresponding GridViewRow and GridViewCell.

“`csharp
string cellValue = GridView1.Rows[rowIndex].Cells[cellIndex].Text;
“`

Replace GridView1 with the ID of your GridView, rowIndex with the index of the row (starting from 0), and cellIndex with the index of the cell in the row (also starting from 0). The cellValue variable will hold the value of the desired cell.
