自动填充文本框datagridview [英] autocomplete textbox datagridview

问题描述

为什么这个代码除了datagridview之外还适用于我的文本框，而不是datagridview中的文本框？

我现在已经玩了近2个小时。一切都说这应该有用

Why does this code work for my textbox besides the datagridview, but not the textbox in the datagridview?
I have puzzeled and searced for almost 2 hours now. Everything says this should work

private void dgvFunn_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            if (this.dgvFunn.CurrentCell.ColumnIndex == this.dgvFunn.Columns["Virkestoff"].Index)
            {

                if (Snacks.acscVirkestoff == null)
                {
                    Snacks.acscVirkestoffFyll();
                }

                tbAntKvartaler.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                tbAntKvartaler.AutoCompleteSource = AutoCompleteSource.CustomSource;

                TextBox cbo = new TextBox();
                cbo = (TextBox)e.Control;
                cbo.AutoCompleteMode = AutoCompleteMode.Append;
                cbo.AutoCompleteSource = AutoCompleteSource.CustomSource;
                cbo.AutoCompleteCustomSource = Snacks.acscVirkestoff;

                tbAntKvartaler.AutoCompleteCustomSource = Snacks.acscVirkestoff;
            }
        }

推荐答案

为什么要创建新的文本框只是为了在下一行重新分配它？

Why are you creating a new Textbox only to reassign it in the next line?

TextBox cbo = new TextBox();
cbo = (TextBox)e.Control;

TextBox cbo = (TextBox)e.Control;

我假设你已经调试并变化了e.Control是一个文本框。怎么了？ 这不起作用不是非常具有描述性或有帮助。

I assume you have debugged and varified e.Control is a textbox. What is happening? "This doesn't work" isn't very descriptive or helpful.

仍有问题。这看起来很奇怪。

Still having problems with this. This seems very odd.

private void dgvFunn_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            TextBox te = e.Control as TextBox;
            te.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            te.AutoCompleteCustomSource.AddRange(new string[] { "one", "two", "three" });
            te.AutoCompleteSource = AutoCompleteSource.CustomSource;
            

        }

仍然无法为我工作，当我在任何列中打字母o时没有自动完成，它通过此代码运行，但在UI中没有任何操作

Still wont work for me, no autocomplete when i punch the letter o in any columns, it runs trough this code but does nothing in the UI

m ***** f *****。



最后我解决了这个问题。如果defaultcellstyle上的wrapmode设置为true，则无法使用上面的代码自动完成。设置wrapmode false是（愚蠢的）解决方案



这么多小时我用过这个！

m***** f*****.

Finally i solves this sh*t. If the wrapmode on the defaultcellstyle is set to true, you cannnot autocomplete with above code. Setting wrapmode false is the (stupid) solution

so many hours i have used on this!
