Telerik報告顯示動態創建的所有列的相同數據

Question

我已經使用Visual Studio創建了一個telerik報告並從DataTable設置了數據源。我使用Telerik.Reporting.TableGroup在運行時動態創建列。現在我在這裏遇到的問題是報告顯示所有字段的相同數據，並且當我調試它時，會爲不同的字段設置不同的字段。

我使用的代碼如下：

在評論

private void Report4_NeedDataSource(object sender, EventArgs e) 
{ 
    DataTable dt = new DataTable(); 
    dt = SalesReport.reportDataTable; 
    table1.DataSource = dt; 

    Telerik.Reporting.HtmlTextBox textboxGroup; 
    Telerik.Reporting.HtmlTextBox textBoxTable; 
    table1.ColumnGroups.Clear(); 
    table1.Body.Columns.Clear(); 
    table1.Body.Rows.Clear(); 
    int ColCount = dt.Columns.Count; 

    for (int i = 0; i <= ColCount - 1; i++) 
    { 
    Telerik.Reporting.TableGroup tableGroupColumn = new Telerik.Reporting.TableGroup(); 
    table1.ColumnGroups.Add(tableGroupColumn); 
    textboxGroup = new Telerik.Reporting.HtmlTextBox(); 
    textboxGroup.Style.BorderColor.Default = Color.Black; 
    textboxGroup.Style.BorderStyle.Default = BorderType.Solid; 
    textboxGroup.Value = dt.Columns[i].ColumnName; 
    textboxGroup.Size = new SizeU(Unit.Inch(1.5), Unit.Inch(0.6)); 

    tableGroupColumn.ReportItem = textboxGroup; 
    textBoxTable = new Telerik.Reporting.HtmlTextBox(); 
    textBoxTable.Value = "=Fields." + dt.Columns[i].ColumnName; 
    textBoxTable.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3)); 
    table1.Body.SetCellContent(0, i, textBoxTable); 
    table1.Items.AddRange(new ReportItemBase[] { textBoxTable, textboxGroup }); 

    } 

}

沒有足夠的空間，但不幸的是這裏是我的建議/建議。我不確定您的具體錯誤，但是在過去，我在重新使用變量時遇到了問題。您在for語句之外聲明您的變量，這可能是導致問題的原因。

private void Report4_NeedDataSource(object sender, EventArgs e) 
{ 
    DataTable dt = new DataTable(); 
    dt = SalesReport.reportDataTable; 
    table1.DataSource = dt; 

    //Telerik.Reporting.HtmlTextBox textboxGroup; 
    //Telerik.Reporting.HtmlTextBox textBoxTable; 
    table1.ColumnGroups.Clear(); 
    table1.Body.Columns.Clear(); 
    table1.Body.Rows.Clear(); 
    int ColCount = dt.Columns.Count; 

    for (int i = 0; i <= ColCount - 1; i++) 
    { 
    Telerik.Reporting.TableGroup tableGroupColumn = new Telerik.Reporting.TableGroup(); 
    table1.ColumnGroups.Add(tableGroupColumn); 

    var textboxGroup = new Telerik.Reporting.HtmlTextBox(); 
    textboxGroup.Style.BorderColor.Default = Color.Black; 
    textboxGroup.Style.BorderStyle.Default = BorderType.Solid; 
    textboxGroup.Value = dt.Columns[i].ColumnName; 
    textboxGroup.Size = new SizeU(Unit.Inch(1.5), Unit.Inch(0.6)); 
    tableGroupColumn.ReportItem = textboxGroup; 

    var textBoxTable = new Telerik.Reporting.HtmlTextBox(); 
    textBoxTable.Value = "=Fields." + dt.Columns[i].ColumnName; 
    textBoxTable.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3)); 
    table1.Body.SetCellContent(0, i, textBoxTable); 

    table1.Items.AddRange(new ReportItemBase[] { textBoxTable, textboxGroup }); 
    } 

}

我建議閱讀以下文章。我發現了同樣的問題，我的解決方案是爲組列，標籤和詳細信息文本框添加唯一的名稱。

//Added 
tableGroupColumn.Name = "group" + *something_uniquegoeshere*; 

//Added 
textboxGroup.Name = "label" + *something_uniquegoeshere*; 

//Added 
textBoxTable.Name = "data" + *something_uniquegoeshere*;
