动态填充RadGridView

问题描述

我正在使用RadControls for WinForms 2011 Q3

I am using RadControls for WinForms 2011 Q3

RadGridView的数据源是根据用户的输入/选择动态生成的
每当数据源为生成后，我将调用SetDatasource2KeyValuesGrid（）
我希望看到的是生成的列和在gridview中填充的值。
但是我看到的是生成了列，但是没有填充值，即使gridview中的行数与其datasource（keyValuesList）中的项目数匹配也是如此。
我一定错过了一些简单的东西。请帮忙。谢谢

The datasource for a RadGridView is dynamically generated based on users' input/selectionEverytime when a datasource is generated, I will call SetDatasource2KeyValuesGrid()What I expect to see is columns generated and values filled in gridview.However what I see is columns generated but no value filled even though the number of rows in gridview match the number of items in its datasource(keyValuesList)I must have missed something simple. Please help. thanks

编辑：
我从列表keyValueList创建了一个DataTable，然后将其分配给DataSource，然后它起作用了
只是想知道是否有一个更好的方法。谢谢

I create a DataTable from the list keyValueList, and then assign it to DataSource, then it worksJust wonder if there's a better way. thanks

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;
}

public class FeedKeyValueOneSet
{
    public FeedFieldValues[] KeyValueOneSet;
}

public class FeedFieldValues
{
    public string key { get; set; }
    public string value { get; set; }
}

推荐答案

我从列表中的keyValueList，然后将其分配给DataSource，然后它可以工作
，请参见编辑该问题的代码
