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!!!

对于您的问题

对于gridview中的模板项目，一旦完成数据绑定，则应通过循环分配值.

For Your issue

For template items in gridview, once you did databind then you should assign the values through loop.
example

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

最合理的方法是修改数据源以包含新数据，然后重新绑定.



您应该编辑自己的帖子，而不是发布虚假的答案".

无论数据来自何处，都需要对其进行更新以包括所需的行，然后将数据与新行绑定.我不明白这段代码与您的问题有何关系.

如果答案不是来自您的数据库，为什么要将它们绑定到网格?在这种情况下，您应该创建一个带有答案的问题集合，将其构建在内存中，然后绑定到该问题.

The most logical way to do this, is to modify your data source to contain the new data, and then rebind.



You should edit your post, not post fake ''answers''.

Where-ever your data comes from, you need to update it to include the rows you want, then bind the data with the new rows. I don''t understand how this code is related to your question.

If the answers do not come from your db, why are you binding them to a grid ? In that case, you should create a collection of questions with answers, build it in memory, and bind to that.
