将值和文本动态绑定到DropDownlist [英] Dynamic binding of value and text to a DropDownlist

问题描述

我发现当我将行绑定到Arraylist的dropdownlist时，"value"和"text"都分配了相同的值.

我不想要这个，有没有办法相应地绑定值?

请帮助我，谢谢!!

Hi,

I found that when I bind rows to a dropdownlist from an Arraylist both the ''value'' and ''text'' were assigned to the same value.

I don''t want this, is there a way to bind the values accordingly?

Please help me,Thank you!!

推荐答案

希望它能起作用.....
dropdownlist1.datavaluefield.text
dopdownlist1.datatextfield.text

hope it works.....
dropdownlist1.datavaluefield.text
dopdownlist1.datatextfield.text

填充数据表中的数据.然后将此数据表保留到DropDownList.

Fill the the data''s in DataTable. Then assisgn this DataTable to the DropDownList.

ddl.DataSource = dataTable
ddl.DataValueField = "value field name"
ddl.DataTextField = "textfield name"
dd.DataBind()

OleDbConnection con = new OleDbConnection(connection);
                DataSet ds = new DataSet();
                OleDbDataAdapter ad = new OleDbDataAdapter("select Tittle from smsstorage order by Tittle Asc", con);
                ad.Fill(ds);
                //ddlsmsstorage.Items.Clear();
                ddlsmsstorage.Items.Add("---Select---");


                for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                {
                    ddlsmsstorage.Items.Add(ds.Tables[0].Rows[i][0].ToString());

               
                   
                }

这样我们也可以添加您想要的字段..........

like this also we can add which field you want.............
