将所选列表框项从ownform传递到主窗体 - C＃

本文介绍了将所选列表框项从ownform传递到主窗体 - C＃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 我在主窗体中有一个datagridview。通过单击datagridview的特定列，它将打开子表单或ownedform（动态创建）。拥有的表单有一个列表框和一个OK按钮。当用户从列表框中选择一个项目并单击确定时，所选文本需要出现在datagridview单元格上。但是当我点击OK时我无法得到结果。我也没有收到任何错误。这是代码 注意：如果使用文本框而不是列表框，我可以传递值到datagridview。我只是不知道如何处理列表框来传递价值。 动态创建所有形式的代码&添加控件 Hi, I have a datagridview in the main form. By clicking on a particular column of datagridview, it will open the sub form or ownedform(dynamically created). The owned form have a listbox and an OK button. When The user selects an item from listbox and click OK then selected text needs to be appear on the datagridview cell. But when i click OK i couldn't get the result. I am not receiving any error neither.Here's the codeNOTE: If use Textbox instead of listbox, i am able to pass the value to datagridview. I just don't know the way to handle listbox to pass value.CODE FOR DYNAMICALLY CREATING OWNED FORM & ADDING CONTROLS private List BUTTON点击事件处理程序 - 不工作（列表框） BUTTON CLICK EVENT HANDLER - NOT WORKING (LISTBOX)private void dbtn_Click_SIGTB(object sender, EventArgs e) { int rowidx = dataGridView3.CurrentCell.RowIndex; int colidx = dataGridView3.CurrentCell.ColumnIndex; foreach(ListBox lb in inputlistboxes) { string selected = lb.GetItemText(lb.SelectedItem); dataGridView2.Rows[rowidx].Cells[colidx].Value = selected; } foreach (Form frm in ownform) frm.Close(); } BUTTON EVAND HANDLER - WORKING（TEXTBOX） BUTTON EVENT HANDLER - WORKING (TEXTBOX)private void dbtn_Click_VARTB(object sender, EventArgs e) { int rowidx = dataGridView2.CurrentCell.RowIndex; int colidx = dataGridView2.CurrentCell.ColumnIndex; foreach (TextBox txt in inputTextBoxes) dataGridView2.Rows[rowidx].Cells[colidx].Value = txt.Text; foreach (Form frm in ownform) frm.Close(); } DATAGRIDVIEW CELL CONTENT CLICK DATAGRIDVIEW CELL CONTENT CLICKprivate void dataGridView3_CellContentClick(object sender, DataGridViewCellEventArgs e) { if (dataGridView3.CurrentCell.ColumnIndex.Equals(3)) { ShowMyOwnedForm_SIGTB(); } } 我尝试了什么： private void dbtn_Click_SIGTB（object sender，EventArgs e） { int rowidx = dataGridView3.CurrentCell.RowIndex ; int colidx = dataGridView3.CurrentCell.ColumnIndex; foreach（输入列表框中的ListBox lb） { string selected = lb.GetItemText（lb.SelectedItem）; dataGridView2.Rows [rowidx] .Cells [colidx] .Value = selected; } foreach（表格frm in ownform） frm.Close（）; } What I have tried:private void dbtn_Click_SIGTB(object sender, EventArgs e) { int rowidx = dataGridView3.CurrentCell.RowIndex; int colidx = dataGridView3.CurrentCell.ColumnIndex; foreach(ListBox lb in inputlistboxes) { string selected = lb.GetItemText(lb.SelectedItem); dataGridView2.Rows[rowidx].Cells[colidx].Value = selected; } foreach (Form frm in ownform) frm.Close(); }推荐答案 只需更新您的 dbtn_Click_SIGTB 函数，如下所示： hi just update your dbtn_Click_SIGTB function as follows,private void dbtn_Click_SIGTB(object sender, EventArgs e){ int rowidx = dataGridView3.CurrentCell.RowIndex; int colidx = dataGridView3.CurrentCell.ColumnIndex; foreach(ListBox lb in inputlistboxes) { string selected = lb.Items[lb.SelectedIndex].ToString(); //lb.GetItemText(lb.SelectedItem); dataGridView2.Rows[rowidx].Cells[colidx].Value = selected; } foreach (Form frm in ownform) frm.Close();} 这篇关于将所选列表框项从ownform传递到主窗体 - C＃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！
