如何使用放置在gridview中的图像按钮重定向到另一个页面,方法是检查其他列中的项目模板(标签)值是否等于给定文本。
this is my code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter("select ID,SurveyName from SurveyMaster1 union select -1,'Select'", con);
da.Fill(dt);
DropDownList1.DataSource = dt;
DropDownList1.DataValueField = "ID";
DropDownList1.DataTextField = "SurveyName";
DropDownList1.DataBind();
DropDownList1.SelectedValue = "-1";
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter("SELECT Question,QuestionType FROM Questions WHERE SurveyID = '"+ DropDownList1.SelectedValue.ToString() +"'" , con);
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void imgbtnEdit_Click(object sender, ImageClickEventArgs e)
{
GridViewRow grdSelRow = GridView1.SelectedRow;
TextBox textInt = (TextBox)GridView1.FindControl("text1");
if (textInt.Text == "Text")
{
Response.Redirect("Text.aspx");
}
}
任何人都请帮助我..可能是我的问题不太清楚。

在gridview的RowCommand事件中编写代码
提供图像按钮CommandName property =“Edit”
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("Edit"))
{
TextBox textInt = (TextBox)GridView1.Rows[e.RowIndex].FindControl("text1");
if (textInt.Text == "Text")
{
Response.Redirect("Text.aspx");
}
}
}
