I have two bound fields and one check box in grid view . And the values in bound field comes from the table . Now i want to access the value of the autoid and store in it a session of the selected checkbox.

推荐答案

我不清楚你的问题.您是否要在gridview中保留行的主键?如果是这样，您可以为此使用隐藏字段.

Hi,

I am not clear on your question. Do you want to keep primary key of the rows in the gridview? If so you can use a hidden field for this.

使用此

Use this

GridView1.DataKeys[index].Value.ToString()

这里index是gridview的行索引

here index is row index of gridview

You can have multiple datakeys to access them see this link

DataKeyNames[^]

尝试以下操作:

Try this one:

GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
HiddenObjectID.Value = Convert.ToString(GvUserDetails.DataKeys[row.RowIndex].Value);
