我正在使用紧凑型框架2.0在我的windows ce掌上电脑上开发一个c＃应用程序。 我有一个像下面的网格

我已经使用datagrid进行网格形成。注意：DataGrid（新的System.Windows.Forms.DataGrid（））不是DataGridView。 网格上方有一个文本框。如果用户在文本框中键入英文，我必须更改数据网格中第二行的颜色。 我怎么实现它？
private System.Windows.Forms.DataGrid scnDataGrd = new System.Windows.Forms.DataGrid();
我添加了一个名为status的coloumn。我想在那里显示图像。如果文本框中的文本匹配。
将表格添加到表格并根据csv填充值：
if (data.StartsWith("Coloumns"))
data = data.Substring(index + 1, data.Length - (index + 1));
data = data.Trim();
string[] values = data.Split(',');
// Add the index on the column on which data is stored in csv
List<int> csvIndex = new List<int>();
for (int i = 0; i < values.Length; i++)
{
values[i] = values[i].Trim();
if (values[i] != "Status")
csvIndex.Add(csvHeaders.IndexOf(values[i]));
}
rfidindex = (csvHeaders.IndexOf("RFID") == -1) ? csvHeaders.IndexOf("rfid") : csvHeaders.IndexOf("RFID");
//Image myImage = new Bitmap(Assembly.GetExecutingAssembly().GetManifestResourceStream("search.png"));
//ImageConverter imageConverter = new ImageConverter();
Image img = AssetGatherMobileQuickTraQ.Properties.Resources.search;
//Properties.Resources.my_image;
string csvdata = strRdr.ReadToEnd();
csvdata = csvdata.Replace('\r', ' ');
string[] tagDets = csvdata.Split(new char[] { '\n' });
csvItems = new Hashtable();
DataTable dataTable1 = (DataTable)scnDataGrd.DataSource;
for (int i = 0; i < tagDets.Length; i++)
{
string[] individTagDet = tagDets[i].Split(new char[] { ',' });
if (individTagDet.Length <= 1)
break;
csvItems.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim(), individTagDet);
DataRow row = dataTable1.NewRow();
row.BeginEdit();
//System.Drawing.Image imgTest = System.Drawing.Image. FromFile("C:\\Test.jpg");
//System.Drawing.Image img = System.Drawing.Image.ReferenceEquals
//dataTable1.Columns
Bitmap image1 = new System.Drawing.Bitmap(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\search.png");
//scnDataGrd.Dara
row[0] = image1;
//DataGrid
for (int j = 0; j < 3; j++)
{
row[j+1] = individTagDet[csvIndex[j]].Replace("\"",string.Empty).Trim();
}
//scnDataGrd.TableStyles
csvRfidList.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim());
missingTagList.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim());
row.EndEdit();
dataTable1.Rows.Add(row);
scnDataGrd.DataSource = dataTable1;
}
如果文本匹配到达此处：
DataTable dataTable = (DataTable)scnDataGrd.DataSource;
int index1 = -1;
bool found = false;
DataGridTableStyle ts = new DataGridTableStyle();
foreach (DataRow dr in dataTable.Rows)
{
index1++;
if (dr[tableColIndex].ToString() == textValue)
{
scnDataGrd.Select(index1);
scnDataGrd.SelectionForeColor = Color.Red;
break;
}
else {
dr[0] = "Not Found";
}
}
在Status Coloumn中，而不是图像，它显示为System.Data.Bitmap

尝试更改backColor
int index = -1;
bool found = false;
foreach (DataRow dr in myDataSet.Tables[0].Rows)
{
index++;
string d = dr["location"].ToString();
if (dr[0].ToString() == txtbox1,Text)
{
found=true;
break;
}
}
if(found)
{
scnDataGrd.Select(index);
scnDataGrd.SelectionBackColor = Color.Blue;
}
如果您想更改前颜色，请将 SelectionBackColor 替换为 SelectionForeColor 。这里myDataSet是DataGrid的绑定元素，首先我们找到Data的位置，之后从
中选择该行scnDataGrd.Select(index);
并从
更改选择行的颜色scnDataGrd.SelectionForeColor = Color.Blue;
修改
您可以通过替换
来更新字体颜色scnDataGrd.SelectionBackColor = Color.Blue;
到
scnDataGrd.SelectionForeColor = Color.Blue;

你不能给出这样的图像，你必须为此制作自定义图像视图，但是如果你想要这个来自复选框，你可以这样实现：
if (data.StartsWith("Coloumns"))
data = data.Substring(index + 1, data.Length - (index + 1));
data = data.Trim();
string[] values = data.Split(',');
// Add the index on the column on which data is stored in csv
List<int> csvIndex = new List<int>();
for (int i = 0; i < values.Length; i++)
{
values[i] = values[i].Trim();
if (values[i] != "Status")
csvIndex.Add(csvHeaders.IndexOf(values[i]));
}
rfidindex = (csvHeaders.IndexOf("RFID") == -1) ? csvHeaders.IndexOf("rfid") : csvHeaders.IndexOf("RFID");
//Image myImage = new Bitmap(Assembly.GetExecutingAssembly().GetManifestResourceStream("search.png"));
//ImageConverter imageConverter = new ImageConverter();
Image img = AssetGatherMobileQuickTraQ.Properties.Resources.search;
//Properties.Resources.my_image;
string csvdata = strRdr.ReadToEnd();
csvdata = csvdata.Replace('\r', ' ');
string[] tagDets = csvdata.Split(new char[] { '\n' });
csvItems = new Hashtable();
DataTable dataTable1 = (DataTable)scnDataGrd.DataSource;
for (int i = 0; i < tagDets.Length; i++)
{
string[] individTagDet = tagDets[i].Split(new char[] { ',' });
if (individTagDet.Length <= 1)
break;
csvItems.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim(), individTagDet);
DataRow row = dataTable1.NewRow();
row.BeginEdit();
//System.Drawing.Image imgTest = System.Drawing.Image. FromFile("C:\\Test.jpg");
//System.Drawing.Image img = System.Drawing.Image.ReferenceEquals
//dataTable1.Columns
Bitmap image1 = new System.Drawing.Bitmap(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\search.png");
//scnDataGrd.Dara
row[0] = image1;
//DataGrid
for (int j = 0; j < 3; j++)
{
row[j+1] = individTagDet[csvIndex[j]].Replace("\"",string.Empty).Trim();
}
//scnDataGrd.TableStyles
csvRfidList.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim());
missingTagList.Add(individTagDet[rfidindex].Replace("\"", string.Empty).Trim());
row.EndEdit();
dataTable1.Rows.Add(row);
DataColumn cCurrent = new DataColumn("Current", typeof(bool));
dataTable1.Rows.Add(cCurrent);
scnDataGrd.DataSource = dataTable1;
}
并在您的标准中，您可以像这样制作条件工具..
DataTable dataTable = (DataTable)scnDataGrd.DataSource;
int index1 = -1;
bool found = false;
DataGridTableStyle ts = new DataGridTableStyle();
foreach (DataRow dr in dataTable.Rows)
{
index1++;
if (dr[tableColIndex].ToString() == textValue)
{
scnDataGrd.Select(index1);
scnDataGrd.SelectionForeColor = Color.Red;
dr["Current"] = true;
break;
}
else
{
dr[0] = "Not Found";
}
}
当前的电流
dr [＆＃34; Current＆＃34;] = true;
是我们之前在第三行中实现的DataColumn。以前的代码。
