    [CLOSED] Grid delete is not working

    Hi,

    I am creating dynamic grid. I added dynamic delete button. Delete is working but remaining one record is not working.

        protected void SaveHandler(object sender, BeforeStoreChangedEventArgs e)
    {
        hdJson.Text = e.DataHandler.JsonData;
        ResourceManager.GetInstance(this.Context).AddScript("grid.getStore().submitData();");
    }

    protected void storeSubmitData(object sender, StoreSubmitDataEventArgs e)
    {
        new GenericGrid().submitGridData((bt_admin_panel_user)Session[SystemVariables.SESSION_PARAMETER_USER],
            GuiUtils.getGridConfigName(HttpContext.Current.Request.RawUrl), hdJson.Text);

        ResourceManager.GetInstance(this.Context).AddScript("grid.reload();");
    }
    program doesnt enter storeSubmitData when remaining one record.

    Hi,

    I have prepared a sample in according to the details that you provided but I can't reproduce the issue. In other words SubmitData is fired when there is one record.

    So, how we can reproduce the issue?

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    public object[] MyData = new object[] 
    { 
        new object[] { "test0" },
        new object[] { "test1" },
        new object[] { "test2" }
    };

    protected void Store_RefreshData(object sender, StoreRefreshDataEventArgs e)
    {
        object[] data = this.MyData;
        var limit = e.Limit;
        if ((e.Start + e.Limit) > data.Length)
        {
            limit = data.Length - e.Start;
        }
        object[] rangeData = (e.Start < 0 || limit < 0) ? data : this.GetRange(data, e.Start, limit);
        e.Total = data.Length;
        this.GridPanel1.GetStore().DataSource = rangeData;
    }

    private object[] GetRange(object[] data, int start, int limit)
    {
        object[] result = new object[limit];
        for (int i = 0; i < limit; i++)
        {
            result[i] = data[i + start];
        }
        return result;
    }

    protected void SaveHandler(object sender, BeforeStoreChangedEventArgs e)
    {
        ResourceManager.GetInstance(this.Context).AddScript("GridPanel1.getStore().submitData();");
    }

    protected void StoreSubmitData(object sender, StoreSubmitDataEventArgs e)
    {
        X.Msg.Alert("storeSubmitData", "Hello from storeSubmitData!").Show();
    }
</script>

    hi daniil,

    your code also make the same problem.

    if one record deleted and then click save StoreSubmitData method was called
    if two records deleted and then click save StoreSubmitData method was called
    but all records deleted and then click save StoreSubmitData method couldn't be called.

    Hi,

    Delete is working but remaining one record is not working.
    Well, in according to words above I thought that you meant that SubmitData is not fired when there is one record.

    but all records deleted and then click save StoreSubmitData method couldn't be called.
    Well, there is expected behavior. If there is no data to submit we do not fire SubmitData and return false from .submitData() method (you could handle this case manually).

    Hi,

    'submitData' method submits current records of the store, if store has no records then submit will not be performed because there is no data to submit

    What a sense to create so strange construction (I mean to call submit in the save handler)?
    protected void SaveHandler(object sender, BeforeStoreChangedEventArgs e)
{
    hdJson.Text = e.DataHandler.JsonData;
    ResourceManager.GetInstance(this.Context).AddScript("grid.getStore().submitData();");
}
