我使用成员资格来创建用户并为其分配角色我在我的aspx页面中编写了以下代码...在Creatuser表单向导中输入用户详细信息后，还有另一个选项来选择用户角色，该选项显示在gridview中，带有check框，但无论你从gridview复选框中选择什么角色，它只取最后一个值并插入具有相同角色的用户，而我希望它与所选值一起插入......
这是我在aspx页面中的客户端代码..

GridView1.DataBind();
}
请伙计们帮助我，因为我遇到了这种情况......会很感激......
答案 0 :(得分：0)
试试这个：
这是因为在检查是否选中了复选框之前，您在if条件之外填写RoleName。
public void getrole()
{
string roleName = string.Empty;
foreach (GridViewRow gvrow in gvRoles.Rows)
{
CheckBox chk = (CheckBox)gvrow.FindControl("chkRole");
Label lbl = (Label)gvrow.FindControl("lblRole");
if (chk.Checked)
{
roleName = lbl.Text;
Role=roleName;
Roles.AddUserToRole(txtUserName.Text, roleName);
Label1.ForeColor = Color.Red;
Label1.Text = "The " + txtUserName.Text + " role " + roleName + " Added ";
//Label1.Visible = true;
}
}
}
