将值从组合框传递到文本框

本文介绍了将值从组合框传递到文本框的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在使用桌面应用程序，我遇到的情况是将值成员和显示成员传递给组合框。现在，当我单击一个组合框时，我希望值成员显示在一个文本框上，显示成员显示在另一个文本框上。我怎样才能做到这一点？到目前为止，我的代码看起来像这些 Dim ds As 新 DataSet Dim da 作为 新 SqlDataAdapter Dim cmd As 新 SqlCommand cmd.CommandText = [AP249_Falsifikati]。[ProcGetDostavuvaci] cmd.CommandType = CommandType.StoredProcedure cmd.Connection = con cmd.Parameters.AddWithValue（ @ TipDostavuvac，TipDostavuvac） cmd.Parameters.AddWithValue（ @ Datum，DatumPrimanje） da.SelectCommand = cmd da.Fill（ds， Tabela ） cmbDostavuvaci.Visible = True cmbDostavuvaci.DataSource = ds.Tables（ 0 ）。DefaultView cmbDostavuvaci.ValueMember = MatBR cmbDostavuvaci.DisplayMember = Naziv 解决方案 正如我从您的代码中理解的那样，您可以通过这种方式填充组合框。 并且知道你想把所选的值放在文本框中。 在c＃中它将是： String s = cmbDostavuvaci.SelectedItem.ToString（）; 你好， 因为你说你要展示点击组合框后，在文本框中显示值成员和显示成员。您可以使用 ComboBox.OnSelectedIndexChanged [^ ]完成此任务的方法。以下代码段显示了这一点。 private void cmbDostavuvaci_OnSelectedIndexChanged（ Object sender，EventArgs e）{ txtValue.Text = cmbDostavuvaci.SelectedValue.ToString（）; txtDisplay.Text = cmbDostavuvaci.SelectedText; } 可以找到一个详细的例子此处 [ ^ ]。 问候， http://stackoverflow.com/questions/16673551/value-member-in-textbox-and-display-member-in-组合框 [ ^ ] I am working on a desktop application, and I have a situation where I pass a value member and a display member to a combobox. Now when I click a combobox I want the value member to show on one text box and the display member on the another text box. How can I do that? So far my code looks like theseDim ds As New DataSet Dim da As New SqlDataAdapter Dim cmd As New SqlCommand cmd.CommandText = "[AP249_Falsifikati].[ProcGetDostavuvaci]" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = con cmd.Parameters.AddWithValue("@TipDostavuvac", TipDostavuvac) cmd.Parameters.AddWithValue("@Datum", DatumPrimanje) da.SelectCommand = cmd da.Fill(ds, "Tabela") cmbDostavuvaci.Visible = True cmbDostavuvaci.DataSource = ds.Tables(0).DefaultView cmbDostavuvaci.ValueMember = "MatBR" cmbDostavuvaci.DisplayMember = "Naziv" 解决方案 As i understand from your code, in this way you fill the combobox.And know you want put the selected value in textbox.in c# it will be: String s = cmbDostavuvaci.SelectedItem.ToString();Hello,Since you are saying that you want to show the value member and display member in the textboxes upon click of the combobox. You can use ComboBox.OnSelectedIndexChanged[^] Method to accomplish this. The following code snippet shows this.private void cmbDostavuvaci_OnSelectedIndexChanged(Object sender, EventArgs e) { txtValue.Text = cmbDostavuvaci.SelectedValue.ToString(); txtDisplay.Text = cmbDostavuvaci.SelectedText;}A detailed example can be found here[^].Regards,http://stackoverflow.com/questions/16673551/value-member-in-textbox-and-display-member-in-combobox[^] 这篇关于将值从组合框传递到文本框的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
