Insert not working when using custom/template column

Hello

I am developing a usercontrol using Radgrid. My problem is that when I insert a template column containing a RadAutoCompleteBox the insert command stops firing and the callback from the RadAutoCompleteBox inside the TemplateColumn is invalid. In Edit Mode everything works fine. If I remove the column from the grid the insert command starts firing again and works perfectly, any ideas as to what the problem might be?

the code for my custom column is as follows:

public class GridLookupColumn : GridTemplateColumn

{

private string _lookupDataMember;

public string LookupDataMember

{

get { return _lookupDataMember; }

set { _lookupDataMember = value; }

}

private string _lookupTextField;

public string LookupTextField

{

get { return _lookupTextField; }

set { _lookupTextField = value; }

}

private string _lookupValueField;

public string LookupValueField

{

get { return _lookupValueField; }

set { _lookupValueField = value; }

}

public class LookupActionTemplate : IBindableTemplate

{

public GridLookupColumn Column = null;

public void InstantiateIn(Control container)

{

RadAutoCompleteBox lookup = new RadAutoCompleteBox();

lookup.ID ="LC" + this.Column.UniqueName;

lookup.DataSource = Column.Owner.OwnerGrid.DataSource;

lookup.DataMember = Column.LookupDataMember;

lookup.DataTextField = Column.LookupTextField;

lookup.DataValueField = Column.LookupValueField;

lookup.EnableViewState = true;

container.Controls.Add(lookup);

lookup.DataBind();

lookup.DataBinding += new EventHandler(LookupDataBindingHandler);

lookup.EntryAdded += new AutoCompleteEntryEventHandler(EntryAddedHandler);

}

private void EntryAddedHandler(object sender, EventArgs e)

{

RadAutoCompleteBox lookup = sender as RadAutoCompleteBox;

if (lookup.Entries.Count > 1)

{

lookup.Entries.RemoveAt(0);

ExtractValues(lookup.NamingContainer as GridDataItem);

}

private void LookupDataBindingHandler(object sender, EventArgs e)

{

RadAutoCompleteBox lookup = sender as RadAutoCompleteBox;

GridDataItem item = (GridDataItem)lookup.NamingContainer;

string id = DataBinder.Eval(item.DataItem, this.Column.DataField).ToString();

string text = String.Empty;

DataSet data = (DataSet)Column.Owner.DataSource;

foreach (DataRow r in data.Tables[Column.LookupDataMember].Rows)

{

if (r[Column.LookupValueField].ToString() == id)

{

text = r[Column.LookupTextField].ToString();

}

AutoCompleteBoxEntry entry = new AutoCompleteBoxEntry(text, id);

if(text != String.Empty)

lookup.Entries.Add(entry);

}

public System.Collections.Specialized.IOrderedDictionary ExtractValues(Control container)

{

IOrderedDictionary values = new OrderedDictionary();

RadAutoCompleteBox lookup = container.FindControl("LC" + Column.UniqueName) as RadAutoCompleteBox;

values.Add(Column.UniqueName, lookup.Entries[0].Value);

return values;

}

public class LookupTemplate : ITemplate

{

public GridLookupColumn Column = null;

public void InstantiateIn(Control container)

{

Label l = new Label();

l.ID = Column.UniqueName;

container.Controls.Add(l);

l.DataBinding += new EventHandler(LookupDataBindingHandler);

}

private void LookupDataBindingHandler(object sender, EventArgs e)

{

Label l = sender as Label;

GridDataItem item = (GridDataItem)l.NamingContainer;

string id = DataBinder.Eval(item.DataItem, this.Column.DataField).ToString();

DataSet data = (DataSet) Column.Owner.DataSource;

foreach (DataRow r in data.Tables[Column.LookupDataMember].Rows)

{

if (r[Column.LookupValueField].ToString() == id)

{

l.Text = r[Column.LookupTextField].ToString();

}

public GridLookupColumn()

{

LookupActionTemplate lookupActionTemplate = new LookupActionTemplate();

LookupTemplate lookupTemplate = new LookupTemplate();

lookupTemplate.Column = this;

lookupActionTemplate.Column = this;

this.EditItemTemplate = lookupActionTemplate;

this.ItemTemplate = lookupTemplate;

this.InsertItemTemplate = lookupActionTemplate;

}

I create the grid on Page Load as described in the documentation.

Any help is highly appreciated

Best Regards,

Claus Veirup

By default bind values to DetailedTable

This is my requirement,

I have a radgrid - that shows project names
I have a detailed table - that shows project details

So by default i want to expand all the projects and bind the project details to detailed table. The DataSource value for detailed table will be from SQL.

Please give me a link for similar sample. Or tell me some idea.

Right now, i tried to expand the node by default in prerender method. But the detailed table's datasource is coming from the Grid i.e. the project names is displayed in detailed table also.

Any Suggestion?

BTW ... the RadAjaxmanager for RAD 2007 Q1 SP1 works fine ...

                        </XAxis>
            </PlotArea>
        </telerik:RadChart>

here the sql result:

slotcount	count	pc_to_total	labelPerc
n°1 Slot	24	6.25	6.25%
n°2 Slot	3	7.81	7.81%
n°10 Slot	1	10.42	10.42%
n°11 Slot	1	13.28	13.28%
n°333 Slot	1	100	100.00%

and here the result:

My problem is that the line does not have to go down and it happens when i use type=Spline to have the curved line...
Can You please help me to understand if this is my fault or if this is telerik issue and can i do anything to show a correct curved line?

PDF Export Header Alignment

When my grid is displayed, my headers are aligned to the left. However, when the grid is exported, the headers are all aligned to the center. Is there a way to keep the alignment to the left when exporting to PDF?
