我遇到这种情况:
...带有数据的普通RadGrid。并且,如果我连续clic,我想得到这个:
...标签 - 文本框对列表(请注意:这些数据列表是从行中获取的,但不属于该行)。
使用第一台RadGrid,一切都还好。 因此,我使用了一个简单的HTML表作为对的列表(在第二个图像中)。此列表是从数据库生成的代码隐藏。
问题是TextBoxs的更新:如果我编辑这些文本框并在Update Botton上执行clic,则启动 myRadGrid_UpdateCommand 方法。但我无法找到管理这些文本框的方法(它们不会出现在 myRadGrid.Controls 中)。
所以我试图在第一个RadGrid中使用另一个RadGrid,但没有运气......也许我必须使用另一个不同的Telerik控件?
有人知道我该怎么做吗?
这是我实施的一部分:
protected void myRadGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
{
this.myRadGrid.DataSource = this.dtListaDettagli;
this.dtListaDettagli.PrimaryKey = new DataColumn[] { this.dtListaDettagli.Columns["key"] };
}
protected void myRadGrid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
{
GridEditFormItem item = (GridEditFormItem)e.Item;
UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
var listOfDetails = this.Session["listOfDetails"];
//...
var dtoTrav = (List<Detail_Type_N>) listOfDetails;
PopolaUC(dtoTrav, userControl, e.Item.ItemIndex);
}
}
private void PopolaUC<T>(List<T> data, UserControl uc, int index) where T : FlussiBaseDto
{
// ...
RadPane radPane = uc.FindControl("RadPane1") as RadPane;
var properties = TypeDescriptor.GetProperties(typeof(Detail_Type_N));
// ...
var dettaglioSelected = (from x in data
where x.IdFlusso == idFlussoSelected && x.ProgDettaglio == progDettaglioSelected
select x).FirstOrDefault();
HtmlTable htmlTable = new HtmlTable();
htmlTable.ID = "DettaglioSinistro";
var tRow = new HtmlTableRow();
int i = 0;
foreach (PropertyDescriptor prop in properties)
{
i++;
if (i > 3) // organizza la sottotabella in 2 colonne
{
tRow = new HtmlTableRow();
i = 1;
}
// Set label:
HtmlTableCell tLabel = new HtmlTableCell();
var stringInNormalCase = Regex.Replace(prop.Name, "(\\B[A-Z])", " $1");
tLabel.InnerText = stringInNormalCase;
tRow.Cells.Add(tLabel);
// Set TextBox:
HtmlTableCell tCell = new HtmlTableCell();
// ...
TextBox box = new TextBox();
box.Text = Convert.ToString(prop.GetValue(detailSelected));
box.ID = string.Format("my_{0}", prop.Name);
tCell.Controls.Add(box);
tRow.Cells.Add(tCell);
htmlTable.Rows.Add(tRow);
}
radPane.Controls.Add(htmlTable);
}
protected void myRadGrid_UpdateCommand(object source, GridCommandEventArgs e)
{
GridEditableItem editedItem = e.Item as GridEditableItem;
UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
//Prepare new row to add it in the DataSource
DataRow[] changedRows = this.dtListaDettagli.Select("key = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["key"]);
// ... and then?
catch (Exception ex)
{
changedRows[0].CancelEdit();
Label lblError = new Label();
lblError.Text = string.Format("Errore nell'aggiornamento movimento. Errore: {0} ", ex.Message);
lblError.ForeColor = System.Drawing.Color.Red;
RadGridIpa.Controls.Add(lblError);
e.Canceled = true;
}
}
答案 0 :(得分:0)
您无法动态生成文本框和标签。
相反,您想使用Edit Form。
例如,
<telerik:RadGrid ID="RadGrid1" ...>
<MasterTableView>
...
<EditFormSettings>
Place those textboxes and lables here.
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>
