父母/孩子GridView的问题 [英] Problem with Parent / child gridview

问题描述

我对此有点困惑，

我的要求是，我在父网格中有一个嵌套的gridview，我有一个PK col，在我的子网格脚注模板中，我有一个下拉列表和文本框以及Add linkBut​​ton.Click添加按钮数据必须存储在临时数据表中.那张表我想绑定到我的子网格中，

i''m little bit confusion about this ,

what is my requirement is i have a nested gridview in that parent grid i have a PK col, and in my child grid footer template i have a dropdown and textbox and Add linkButton.Click on Add button data has to be stored in temprory datatable.And that table i want to bind in my child Grid,

ParentGrid                                                 ChildGrid
Doc_No                                                 Material         Quantity
1                                                      pipes           10
                                                       cubes            2

现在的问题是插入第一行父网格详细信息之后，每当我插入第二行父网格值时，它都将显示如下

now what is the issue is after inserting the first row of parent grid details,whenever i insert the 2nd row of parent grid values it''s show like this

ParentGrid                                                 ChildGrid
Doc_No                                                 Material         Quantity
1                                                      pipes           10
                                                       cubes            2
2                                                      Pipes           10
                                                       cubes            2
                                                       piping           3

但是在第二行中，我仅插入管道为3，但是在我的临时数据表中我已经有了管道和多维数据集的信息.因此，它在第二行中显示了所有数据.取决于PK col.为此，我在子网格中添加了一个col Doc_no.

but in 2nd row i''m inserting only piping is 3 but in my temprory DataTable already i have Pipe''s and cube''s information .So, its displayed all the data in 2nd row.hara i want to try to filtering depending upon the PK col . for that i''m adding in my child grid one more col Doc_no.

Doc_No                                       Material  Quantity  Doc_no
1                                            Pipes      10        1
                                             cubes      2         1
2                                            Pipes      10        1
                                             cubes      2         1
                                             Piping     8         2

现在，假设这是我的临时数据表，我将根据Doc_no col进行过滤，这很容易显示.这是我的任务.

谁能帮我解决这个问题...
