如何使用数据绑定和sql保存richtextbox rtf [英] How to save richtextbox rtf using databinding and sql

问题描述

好的我有一个我在Visual Studio 2013中制作的#windows窗体程序

我有一个文本框设置为将文本属性数据绑定到我的sql数据库中的表

使用数据集

所以我的数据从文本框自动保存到数据库并回读到文本框

now

我需要将我的文本框更改为richtextbox，以便我可以加粗，更改颜色等字体。

我看不到如何使用数据绑定绑定和读回rtf属性

我试过这个



notesRichTextBox.DataBindings.Add（new Binding（Rtf，MyProgramDataSet.RTFTable，RTF））;

但是当我重新打开表单时，它只会在colomn中放入一些rtf数据并且在richtextbox中没有显示任何内容

我尝试设置notesRichTextBox.Text = notesRichTextBox.Rtf并且它只显示了所有底层rtf代码/文字



请帮助

我也在开始尝试使用t设置数据绑定他是VisualStudio界面，但Rtf似乎不是一个选项

我认为这是直接的与你想做的事情有关：一个可以绑定到RTF属性的RichTextBox[ ^ ]。

ok I have a c# windows forms program that I am making in Visual Studio 2013
I had a text box set to databinding text property to a table in my sql database
using a dataset
so my data was auto saved from text box to the database and read back to textbox
now
I needed to change my textbox to a richtextbox so that I could bold, change color etc.. the font.
I do not see how to bind and read back the rtf property using databinding
I tried this

notesRichTextBox.DataBindings.Add(new Binding("Rtf", MyProgramDataSet.RTFTable, "RTF"));
but it only put some rtf data in the colomn and displayed nothing back in the richtextbox when I reopened the form
I tried setting the notesRichTextBox.Text = notesRichTextBox.Rtf and it just showed all of the underlying rtf code/text

Please help
I also tried at the beginning to set the databinding using the VisualStudio interface but Rtf doesn't seem to be an option

解决方案

Refer - Saving and Restoring RichTextBox Formatted Text. Alternate to SaveFile/LoadFile[^]

CodeProject is your friend; the best way to show your appreciation for that friendship is to search CP for articles, and answers, that may assist you, and study them.

I think this is directly related to what you want to do: "A RichTextBox that can Bind to the RTF Property" [^].
