在同一个DataGridView列中的控件不会在初始化网格时呈现

本文介绍了在同一个DataGridView列中的控件不会在初始化网格时呈现的处理方法，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 GOOD                                                  BAD GOOD                                                  BAD 我正在托管不同的控件在DataGridView列。当我同时添加控件时，我初始化网格，控件显示为文本框（BAD）。如果我在DataGridView初始化后添加控件，控件正确呈现（GOOD）。I'm hosting different controls in DataGridView column. When I add controls at the same time I initialize the grid the controls show as Textboxes (BAD). If I add the controls after the DataGridView has been initialized controls render correctly (GOOD).public Form1(){ InitializeComponent(); ControlsInGridViewColumn(); //<- renders controls as textboxes}private void button1_Click(object sender, EventArgs e){ ControlsInGridViewColumn(); //<- does correctly render controls}private void ControlsInGridViewColumn(){ DataTable dt = new DataTable(); dt.Columns.Add("name"); for (int j = 0; j < 10; j++) { dt.Rows.Add(""); } this.dataGridView1.DataSource = dt; this.dataGridView1.Columns[0].Width = 200; DataGridViewComboBoxCell ComboBoxCell = new DataGridViewComboBoxCell(); ComboBoxCell.Items.AddRange(new string[] { "aaa","bbb","ccc" }); this.dataGridView1[0, 0] = ComboBoxCell; this.dataGridView1[0, 0].Value = "bbb"; DataGridViewTextBoxCell TextBoxCell = new DataGridViewTextBoxCell(); this.dataGridView1[0, 1] = TextBoxCell; this.dataGridView1[0, 1].Value = "some text"; DataGridViewCheckBoxCell CheckBoxCell = new DataGridViewCheckBoxCell(); CheckBoxCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter; this.dataGridView1[0, 2] = CheckBoxCell; this.dataGridView1[0, 2].Value = true;} 在初始化过程中如何使控件正确呈现？ strong> How does one make the controls render correctly during initialization? （我动态添加DataGridViews）。 更新： Jacob Seleznev的答案适用于表单但不是用户控件，这是我需要的...这是如何重现：UPDATE: Jacob Seleznev's answer works for Forms but not user controls which is what I need... Here is how to reproduce it:在表单：private void button3_Click(object sender, EventArgs e){ this.Controls.Add(new userCtrl());}用户控制：public partial class userCtrl : UserControl{ public userCtrl() { InitializeComponent(); } protected override void OnLoad(EventArgs e) { ControlsInGridViewColumn(); base.OnLoad(e); } public void ControlsInGridViewColumn() { //same code as above }} 推荐答案这对我有用： protected override void OnLoad(EventArgs e) { ControlsInGridViewColumn(); //<- does correctly render controls base.OnLoad(e); } 这篇关于在同一个DataGridView列中的控件不会在初始化网格时呈现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！
