[CLOSED] GridPanel + Dynamic Columns + Count

[Zarzand]

Hello,

I'm creating dynamic Columns for GridPanel I'm having problem getting the Column count in ColumnMoved AjaxEvent.

        protected void CreateGridColumns()
        {
            grdCenter.ColumnModel.Columns.Add(new RowNumbererColumn());

            for (var a = 0; a < objGridPanelColumnModel.Count; a++)
            {
                var column = new Column();

                column.ColumnID = "Col" + a;
                column.Header = objGridPanelColumnModel[a].ColumnHeader;
                column.DataIndex = objGridPanelColumnModel[a].DataIndex;
                column.Hidden = objGridPanelColumnModel[a].IsHidden;

                grdCenter.ColumnModel.Columns.Add(column);
            }

            if (Ext.IsAjaxRequest)
            {
                grdCenter.Reconfigure();
            }
        }

code]
protected void OnEventColumnMoved(object sender, AjaxEventArgs e)
{
var gridPanelColumn = JSON.Deserialize<Dictionary<string, string>[]>(e.ExtraParams["Value"]);

for (var a = 0; a < grdCenter.ColumnModel.Columns.Count; a++)
{
foreach (KeyValuePair<string, string> column in gridPanelColumn[a])
{
GetUpdateGridPanel(a, column.Key, column.Value);
}

}
}
[/CODE]

Hi,

Do you recreate columns during AjaxEvent?

[Zarzand]

No I Don't

[Vladimir]

Hi,

If you don't recreate it then all dynamic actions will be lost. Therefore during AJaxEvent the Columns collection is empty

[Zarzand]

Do you have a small example that I can use...

[Vladimir]

Hi,

Just call your CreateGridColums function during ajax event

[Zarzand]

Thank You very much Vlad this worked great you can also close the JSON Post

I appreciate it allot...
