获取一个GridView行的单元格值 [英] Get the cell value of a GridView row

问题描述

我使用的GridView控件 - AutoGenerateSelectButton =真，以便获得第1列单元格的值选择行。

I am using the GridView - AutoGenerateSelectButton="True" to select the row in order to get the Column 1 cell value.

我曾尝试：

GridViewRow row = dgCustomer.SelectedRow;
TextBox1.Text = "Cell Value" + row.Cells[1].Text + "";

和写入了单元格数值，但仅此而已。

And it writes the "Cell Value" but nothing else.

我终于能得到行（指数）的数量，但不单元格的值。

I finally was able to get the number of the row (index) but not the cell value.

 GridViewRow row = dgCustomer.SelectedRow;
 TextBox1.Text = row.RowIndex.ToString();

我曾尝试：

I have tried:

TextBox1.Text = dgCustomer.Rows[row.RowIndex].Cells[1].Text;

和仍返回索引行。

任何其他建议？
谢谢！

Any other suggestions? Thank you!

推荐答案

试着改变你的代码

// Get the currently selected row using the SelectedRow property.
GridViewRow row = dgCustomer.SelectedRow;

// And you respective cell's value
TextBox1.Text = row.Cells[1].Text

更新：（根据我的意见）
如果所有你正在尝试得到的是所选行的主键值，然后另一种方法是集

UPDATE: (based on my comment) If all what you are trying to get is the primary key value for the selected row then an alternate approach is to set

的DataKeyNames =yourprimarykey

对于可从后面的代码像下面访问的gridview的定义。

for the gridview definition which can be accessed from the code behind like below.

TextBox1.Text = CustomersGridView.SelectedValue.ToString();
