how to update multiple rows on click of the button used outside the gridview???



where each row in gridview is having

1. A question- (which is binded from the database)
2. an answer- (for this a textbox is used)


i have searched on google but with no results..


how can it be done??

if someone can help???

thanks regards....

foreach (GridViewRow row in gvpostslambook.Rows)
{
LinkButton lbtnpostslambook = (LinkButton)row.FindControl("lbtnargument");
TextBox txtanswer = (TextBox)row.FindControl("txt");
prpobj.questionid = Convert.ToInt32(lbtnpostslambook.CommandArgument);
prpobj.answer = txtanswer.Text.Trim();
mainobj.postslambook(prpobj);
}

prp.questionid的值在gridview中的每一行都出现了，但是文本框的值没有出现....

并感谢您回答了我....

但是我的朋友
撒拉雅
我没有从数据库中获取文本框的值..
我只是在使用文本框插入相应的答案
问题...

您的代码显示我应该从数据库中将文本绑定到循环中的文本框，但是除了那些问题之外，我没有从数据库中得到任何东西....

我仍然不知道我的代码有什么问题！！！

the value for the prp.questionid is comming for each row in gridview but the value of the textbox is not comming....

and thanks that you answered me....

but my friend
thatraja
i am not getting the values of the textbox from the database..
i am just using the textboxes to insert the answers for the corresponding
questions...

your code showing that i should bind the text to the textbox in the loop from the database but i am getting nothing from the database except those questions....

i still do not know whats the problem with my code!!!

推荐答案

gvEmp.DataSource = dtEmployee;
gvEmp.DataBind();
for (int i = 0; i < dtEmployee.Rows.Count; i++)
{
 for (int j = 1; j < dtEmployee.Columns.Count; j++)
 {
  if (j == 1 || j == 2 || j == 3)
  {
   ((TextBox)(gvEmp.Rows[i].Cells[j].Controls[1])).Text = dtEmployee.Rows[i][j].ToString();
  }
 }
}

因此请根据您的需要更改代码

so change the code based on your need
