大虾,,帮忙啊,一下午了.button事件怎样取得gridview模板列中panel控件中的textbox的值.急啊....................
如题.
int n = Convert.ToInt16(MessId); // 我可以得到我所选行的第一个字段值,也就是id
Panel panel = (Panel)this.GridView1.Rows[n].Cells[2].FindControl("Panel1");
TextBox text = (TextBox)panel.FindControl("TextBox1");
报错,
索引超出范围。必须为非负值并小于集合大小。
参数名: index
谢谢!!!!!
Panel panel = (Panel)this.GridView1.SelectedRow.Cells[2].FindControl("Panel1");
TextBox text = (TextBox)panel.FindControl("TextBox1");
string ReplyMess = text.Text.ToString();
这种方法取不到值啊?????///!!!!1

第一个字段值跟Rows[n]没有关系吧，n超出Rows.Count了。
直接使用RowCommand()方法不就行了？
GridView1_RowCommand(object sender, GridViewRowEventArgs e)
{
int n = e.Row.RowIndex; //获取行号
Panel panel = (Panel)this.GridView1.Rows[n].Cells[2].FindControl("Panel1");
TextBox text = (TextBox)panel.FindControl("TextBox1");
...
}
这样试试

如果你的GridView控件设置了 AutoGenerateSelectButton="True"，或者包含了一个命令为Selected的按钮列，那么下面的方法是可以取道数据的：
GridViewRow row = this.GridView1.SelectedRow;
string tmp = ((TextBox)row.FindControl("TextBox1")).Text;
Response.Write(tmp);
如果lz已经得到了MessId（不管你是用什么方法得到的），下面这样也可以取得：
string MessId = "";
GridViewRow row = null;
foreach (GridViewRow iRow in this.GridView1.Rows)
if (iRow.Cells[0].Text = MessId) row = iRow;
if (row != null)
{
string tmp = ((TextBox)row.FindControl("TextBox4")).Text;
Response.Write(tmp);
}

你太厉害了.佩服啊!可以取到值了.开始的效果是:点某一行的"选择"本行的第二列panel会显示,再点其他的,这行panel就会消失,点的其他行会显示.可现在是,任意点,都会显示的.Top
