使用c＃将数据表值投标到asp.net中的gridview。 [英] Bidning the data table values row in to gridview in asp.net using c#.

问题描述

在运行模式下如下



主要代码AMC（Dropdownlist1）次要代码AFF（dropdownlist2）按钮（添加）

BMC



当用户在Dropdownlist1中选择AMC并在Dropdownlist2中选择AFF并单击gridview中的添加按钮时，我希望例外输出如下



Majorcode Minorcode

AMC AFF



类似用户在dropdownlist1中选择AMC并在Dropdownlist2中选择BMC并点击添加gridview中的按钮我希望例外输出如下



Majorcode Minorcode

AMC AFF

AMC BMC


添加按钮代码如下



protected void btnadd_Click（object sender，EventArgs e）

{

Dt.Columns.AddRange（new DataColumn [2] {new DataColumn（Major Code，typeof（string）），

new DataColumn（Minor Code，typeof（string））}）;

Dt.Rows .Add（ddlmjrcode.SelectedItem.ToString（），ddlminorcode.SelectedItem.ToString（））;



gvmajormaster.DataSource = Dt;

gvmajormaster.DataBind（）;

}





但是当我点击gridview中的添加按钮时我得到了输出如下



Majorcode Minorcode

AMC AFF





我没有获得第二排的AMC（主要代码）和BMC（次要代码）。



i不会被排除在外如下



Majorcode Minorcode

AMC AFF

AMC BMC

我怎么能用asp做.net使用c＃。



问候，

Sudha。

In Run Mode as follows

When user select the AMC in Dropdownlist1 and select AFF in Dropdownlist2 and click add button in gridview i want excepted output as follows

Majorcode Minorcode

Similarily when user select the AMC in dropdownlist1 and select the BMC in Dropdownlist2 and click add button in gridview i want excepted output as follows

Majorcode Minorcode

Dt.Columns.AddRange(new DataColumn[2] { new DataColumn("Major Code", typeof(string)),
new DataColumn("Minor Code", typeof(string))});
Dt.Rows.Add(ddlmjrcode.SelectedItem.ToString(), ddlminorcode.SelectedItem.ToString());

gvmajormaster.DataSource = Dt;
gvmajormaster.DataBind();
}


But when i click the add button in gridview my got output as follows

Majorcode Minorcode

推荐答案

你好，

为什么不直接将DataRow添加到DataTable。先声明一个DataRow。然后在DataTable中添加该行。尝试此代码

Hello ,
Why not you add the DataRow directly to DataTable .First declare one DataRow . and then add that row in DataTable .Try this code

//crate one datarow and set the column value accordingly .
drCurrentRow = dtCurrentTable.NewRow();
drCurrentRow[0] = ddlmjrcode.SelectedItem.ToString();
drCurrentRow[1] = ddlminorcode.SelectedItem.ToString();

//now add the datarow in datatable
dtCurrentTable.Rows.Add(drCurrentRow);

//add set the DataSource 
gvmajormaster.DataSource = dtCurrentTable;
gvmajormaster.DataBind();

谢谢

thanks
