为变色控件指定变量 [英] Assign a variable to backcolor control

问题描述

我正在对gridview进行条件格式化。

Hi, I am doing a conditional formatting on my gridview.

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
      
{
string tileInput = Convert.ToString(e.Row.Cells[1].Text);//This retrieved from user input (TextBox) and now its output in gridview, at row 1

string tileDB = Convert.ToString(e.Row.Cells[0].Text); //This is retrieved from database and now its output in gridview, at row 0

if (tileInput == tileDB)
{
e.Row.BackColor = Color.White;
}

else 
{
e.Row.BackColor = Color.Red;
}
}
}

因此，所有不正确的输入都会以红色突出显示。

现在，我想在文本框中删除所有不正确的输入，但我不知道该怎么做。



如果我加上这两个，



string error = tileInput;

TextBoxTileID.Text = tileInput.Replace（错误，）;



文本框中的整个输入被空格替换。



因此可以将e.Row.BackColor = Color.Red分配给变量或布尔值，以便我可以检测到此单元格是红色的，这样我就可以替换文本框中有空格的输入不正确？



非常感谢您的帮助。谢谢！

As a result, all the incorrect input will become red-highlighted.
Now, I would like to delete all incorrect input in text box but I have no idea how to do it.

if i add in these 2,

string error = tileInput;
TextBoxTileID.Text = tileInput.Replace(error, "");

whole input in text box is replaced by empty space.

So is it possible to assign "e.Row.BackColor = Color.Red" to a variable or boolean so that I can detect that this cell is red-colored, so that I can replace the incorrect input with space in text box?

Your help is much appreciated. Thank you!

推荐答案

您可以将该TextBox的ToolTip属性设置为red，之后如果将ToolTip设为red则执行以下操作检查TextBoxes你想做什么。

You can set the ToolTip property for that TextBox as "red" and after that you check for the TextBoxes if having ToolTip as "red" do whatever you want to do.
