当用户单击模板字段的按钮时，我想显示Gridview的行详细信息。我得到输出以使用模板字段在Gridview中显示按钮。但是当用户单击按钮时，它会重新加载页面并显示带有行的空模板。
c＃的完整编码
string selectedColumn;
string[] splitSelectedColumn;
string groupByColumn;
string[] splitGroupByColumn;
ArrayList listBtnOrLbl = new ArrayList();
int compareFlag = 0;
protected void btnRefresh_Click(object sender, EventArgs e)
{
selectedColumn = txtColumnNames.Text;
splitSelectedColumn = selectedColumn.Split(',');
groupByColumn = txtGroupBy.Text;
splitGroupByColumn = groupByColumn.Split(',');

当用户单击“刷新”按钮时，将生成Gridview模板字段。上面的编码是一个生成列和模板字段
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Response.Write("<br/>compare flag checking OVER button count=======================" + listBtnOrLbl.Count);
if (e.Row.RowType == DataControlRowType.DataRow)
{
int size = splitGroupByColumn.Length;
//Button[] lnkBtn = new Button[size];
Label[] lblData = new Label[size];
Response.Write("<br/>Inside button count=======================" + listBtnOrLbl.Count);
if ("button".Equals(listBtnOrLbl[j]))
{
for (int i = 0; i < splitGroupByColumn.Length; i++)
{
Button lnkView = new Button();
lnkView.ID = "lnkView";
lnkView.Text = (e.Row.DataItem as DataRowView).Row[splitGroupByColumn[i]].ToString();
//lnkView.Text = (e.Row.DataItem as DataRowView).Row["Id"].ToString();
lnkView.Click += ViewDetails;
lnkView.CommandArgument = (e.Row.DataItem as DataRowView).Row[splitGroupByColumn[i]].ToString();
e.Row.Cells[i].Controls.Add(lnkView);
}
j++;
}
else
{
for (int i = 0; i < splitGroupByColumn.Length; i++)
{
lblData[i] = new Label();
lblData[i].ID = "lblView";
lblData[i].Text = (e.Row.DataItem as DataRowView).Row[splitGroupByColumn[i]].ToString();
Response.Write("<br/>PRINT label==" + lblData[i].Text);
e.Row.Cells[i].Controls.Add(lblData[i]);
//e.Row.Visible = false;
}
j++;
}
}
protected void ViewDetails(object sender, EventArgs e)
{
Response.Redirect("exit.aspx"); //for testing purpose I gave like this, But this method is not calling i think when user clicks button
Response.Write("testing....");
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('TESTING:')", true);
}
用户单击Button之前的输出 output1 点击按钮后（第一个按钮） output2
我之前已经这样做了，但这是一个小而不是更复杂的代码。这工作正常。那我在这里做错了什么？ 感谢
我认为当用户点击按钮时，ViewDetails（）方法不会调用
