如何在文本框中检索GridView amd显示的隐藏列值

how to retrieve a hidden column value of GridView amd display in a textbox

推荐答案

在gridview的rowupdating事件中添加以下代码:

On rowupdating event of the gridview add this code:

int id = GridView1.DataKeys(e.RowIndex).Value;

这是获取所选行的ID的示例.您可以执行以下操作将其直接传输到文本框中:

that''s an example of getting the ID of the selected row. You can transfer it directly into a textbox by doing:

txtID.Text = GridView1.DataKeys(e.RowIndex).Value.ToString();

如果您只是通过使用Visible = false隐藏该列，则只需执行以下代码即可.这里的0代表所选行的列索引.

If you are just hiding the column by using Visible=false, just simply do the below code. The 0 here represents the column index of the selected row.

txtID.Text = GridView1.SelectedRow.Cells[0].Text

尝试一下

try this

protected void grvItems_SelectedIndexChanged(object sender, EventArgs e)
       {
               //for example, cells[1] is hidden
               txtID.Text = grvItems.SelectedRow.Cells[1].Text;
        }

希望对您有帮助，

您好，Santhosh，

在检索单元格值之前，您可以看到像
这样的单元格值 GVUOM.SelectedRow.Cells [0] .visible = true
字符串val = GVUOM.SelectedRow.Cells [0] .tex;
获得价值后
禁用
GVUOM.SelectedRow.Cells [0] .visible = false;

Hi Santhosh,

before you retrieve a cell value youcan visible cell value like
GVUOM.SelectedRow.Cells[0].visible=true
string val=GVUOM.SelectedRow.Cells[0].tex;
after getting value
disable like
GVUOM.SelectedRow.Cells[0].visible=false;
