winform DataGridView-----1
winform 中的列表展示一般是ListView控件和DataGridView控件。这次就简单的介绍一下DataGridView，不得不说winform的列表展示，如果自己不去润色和扩展，原始的是真的丑。但是说实话
很多大佬都是自定义控件，人家做的效果是相当的棒。我是初学者，可没有这本是。所以为了让列表展示稍微看的过去，我只能稍微润色一下了。哈哈哈哈
DataGridView简单封装：
/// <summary>
/// dataGridView设置
/// </summary>
public static class SetDataGridView
{
/// <summary>
/// 表头设置
/// </summary>
/// <param name="gridView"></param>
/// <param name="dicTitle"></param>t
public static void SetHeader(this DataGridView gridView, List<dataGridViewModel> viewModel)
{
foreach (var item in viewModel)
{
switch (item.colType)
{
case ColType.文本:
gridView.Columns.Add(item.colName, item.colTitle);
break;
case ColType.图标:
gridView.SetImage();
break;
case ColType.按钮:
gridView.SetButton(item.TitleData);
break;
default:
break;
}
}

颜色转换：
/// <summary>
/// 颜色转换
/// </summary>
public class SetColor
{
public static Color colorHx16toRGB(string strHxColor)
{
try
{
if (strHxColor.Length == 0)
{//如果为空
return Color.FromArgb(0, 0, 0);//设为黑色
}
else
{//转换颜色
return Color.FromArgb(System.Int32.Parse(strHxColor.Substring(1, 2), System.Globalization.NumberStyles.AllowHexSpecifier), System.Int32.Parse(strHxColor.Substring(3, 2), System.Globalization.NumberStyles.AllowHexSpecifier), System.Int32.Parse(strHxColor.Substring(5, 2), System.Globalization.NumberStyles.AllowHexSpecifier));
}
}
catch
{//设为黑色
return Color.FromArgb(0, 0, 0);
}
}
}
枚举：
public enum ColType
{
文本,
图标,
按钮
}
Model:
public class dataGridViewModel
{
public string colName { get; set; }
public string colTitle { get; set; }
public ColType colType { get; set; }
public Title TitleData { get; set; }
}
public class Title
{
public string headTitle { get; set; }
public string Text { get; set; }
public string headText { get; set; }
public string color { get; set; }
}
c测试：
//设置行表头的颜色
//dataGridView_Mark.SetHeadColor("#F5F5F5");
dataGridView1.SetHeadColor(250, 250, 250);
//表头文字颜色
// dataGridView_File2.SetHeadFontColor("#F5F5F5");
dataGridView1.SetHeadFontColor(95, 95, 95);
//行表头文字类型
dataGridView1.SetHeadFontType(new Font("楷体", 8, FontStyle.Bold));
//改变标题的行高
dataGridView1.SetHeadRowHeight(30);
//去除第一列空列
dataGridView1.SetRowHeadersVisible();
//行占满
dataGridView1.SetCellRowFull();
//去除最后一行空行
dataGridView1.SetAllowUserToAddRows();
//标题居中
dataGridView1.SetHeadCenter();
List<dataGridViewModel> viewModel = new List<dataGridViewModel>()
{
new dataGridViewModel(){colName="title",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colType=ColType.图标},
new dataGridViewModel(){colName="title1",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title2",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title3",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title4",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title5",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){ colType = ColType.按钮,TitleData=new Title(){ headTitle="btnfile4",Text="按钮",headText="操作" } },
};
dataGridView1.SetHeader(viewModel);
//设置某列隐藏
// dataGridView_ReportList.SetColVisible(new string[] { "PKID", "customer" });
Dictionary<int, int> colWidth = new Dictionary<int, int>()
{
[1] = 30,
[7] = 50,
};
////设置列宽
dataGridView1.SetColWidth(colWidth);
Image image = Properties.Resources.excel;
for (int i = 0; i < 20; i++)
{
dataGridView1.Rows.Add("123", image, "123", "123", "123", "123", "123");
}
效果：
