我正在为 WinForms 2011 Q3 使用 RadControls
RadGridView 的数据源是根据用户的输入/选择动态生成的 每次生成数据源时,我都会调用 SetDatasource2KeyValuesGrid() 我希望看到的是生成的列和填充在 gridview 中的值。然而,我看到的是生成的列,但没有填充值,即使 gridview 中的行数与其数据源(keyValuesList)中的项目数匹配,我一定错过了一些简单的东西。请帮忙。谢谢
编辑:我从列表 keyValueList 创建一个 DataTable,然后将其分配给 DataSource,然后它就可以工作了只是想知道是否有更好的方法。谢谢
private void CreateTableSetDatasource(List<FeedKeyValueOneSet>) keyValueList)
{
if(keyValueList==null) return;
var table = new DataTable();
table.Columns.Add("Check");
foreach (var feedKeyValueOneSet in keyValueList)
{
var oneset = feedKeyValueOneSet.KeyValueOneSet;
foreach (var oneKey in oneset)
{
table.Columns.Add(oneKey.key);
}
break;
}
foreach (var feedKeyValueOneSet in keyValueList)
{
var oneset = feedKeyValueOneSet.KeyValueOneSet;
var numOfCol = oneset.Length + 1;
var obj = new object[numOfCol];
obj[0] = "false";
int idx = 1;
foreach (var oneKey in oneset)
{
obj[idx] = oneKey.value;
idx++;
}
table.Rows.Add(obj);
}
radGridKeyValues.DataSource = table;
}
private void SetDatasource2KeyValuesGrid()
{
if (radGridKeyValues.Columns != null) radGridKeyValues.Columns.Clear();
radGridKeyValues.AutoGenerateColumns = false;
radGridKeyValues.EnableFiltering = false;
radGridKeyValues.ShowFilteringRow = false;
radGridKeyValues.ShowHeaderCellButtons = false;
radGridKeyValues.AllowDragToGroup = false;
radGridKeyValues.AllowAddNewRow = false;
radGridKeyValues.EnableGrouping = false;
var keyValueList = (List<FeedKeyValueOneSet>)TimeSeries.FeedValuesCache[m_strFeedName + "_KEYVALUES"];
if(keyValueList==null) return;
GridViewDataColumn checkBoxColumn = new GridViewCheckBoxColumn("columnState", "columnState");
checkBoxColumn.HeaderText = string.Empty;
if (radGridKeyValues.Columns != null) radGridKeyValues.Columns.Add(checkBoxColumn);
foreach (var feedKeyValueOneSet in keyValueList)
{
var oneset = feedKeyValueOneSet.KeyValueOneSet;
foreach (var oneKey in oneset)
{
var textboxCol = new GridViewTextBoxColumn(oneKey.key, oneKey.key);
textboxCol.Width = 150;
textboxCol.ReadOnly = true;
if (radGridKeyValues.Columns != null) radGridKeyValues.Columns.Add(textboxCol);
}
break;
}
radGridKeyValues.DataSource = keyValueList;
