Hi,

Hi,

There is focusRow function in GridPanel's View. It is ensure visible for row

grid.getView().focusRow(numberOfRow);

Hi Vladsch,

I get "Microsoft JScript runtime error: 'this.getRow(...)' is null or not an object" at

Ext.grid.GridView.override({
    getCell: function (row, col) {
        var tds = this.getRow(row).getElementsByTagName("td");
        var ind = -1;
        for (var i = 0; i < tds.length; i++) {
            if (Ext.fly(tds[i]).hasClass("x-grid3-col x-grid3-cell")) {
                ind++;
                if (ind == col) {
                    return tds[i];
                }
            }
        }
    }
});

because row is Nan. Code is below:

store.DataSource = ds;
store.DataBind();
RowSelectionModel model = (grid.SelectionModel.Primary as RowSelectionModel);
                model.SelectedRows.Add(new SelectedRow(selected.ToString()));
                model.UpdateSelection();
                Coolite.Ext.Web.ScriptManager.GetInstance(HttpContext.Current).AddScript(string.Format("Ext.getCmp('{0}').getView().focusRow({1});", grid.ClientID, selected.RowIndex));

Rowselection is done but grid cannot scroll. selected.RowIndex returns the position of the entity in data source.

What may be the reason ?

Hi,

Script of ScriptManager executes early then script of selection model. Try use AddScript of RowSelectionModel instead ScriptManager

sm.AddScript("Ext.getCmp('{0}').getView().focusRow({1});", grid.ClientID, selected.RowIndex);

hmm. It worked now. Vladsch, is there a documentation on when to use use ScriptManager and coolite controls AddScript methods ? Or can you explain the difference and using Control.AddScript ?

Hi,

At this moment the script sequence depends from control position in page hierarchy. So, the earlier component is placed on the page, the earlier start of the script


We are planning to change it and to save script sequence as user register/call it on server. It is quite important for us and we will try implement it ASAP

[tansu]

Yes, it is very important because I can find every method or property but I always waste time with correcting errors.

Thanks.

We've made some revisions to the sequencing of the scripts. You should no longer require the .AddScript work-around.

New code has been committed to SVN, although we are still running some tests.*
