[CLOSED] how to save GridPanel configuration to db after user changed it during runtime

[tanky65]

More simply: I need to know (i have no idea) how to get in code behind the grid panel's width when it is resized by user or the same for the hidden value.


just want to save gridpanel columns width and hidden value changed by the user during runtime and send them to database linked to the username who dit the job to reload them later.

in behind code i call the function in example in a directevent of a button for saving data.
There I access the values i need in the way you see ( g.ColumnModel.Columns[i]..... ) and I don't get the changed by user values but the original values.
for instance, user changed the width of the first column from original 50 to 145 but in the codebehind i get still 50.

What structure should i access or what should i do?
Thanks in advance

        public static void saveConfigurationGridToDB (GridPanel g, string savegridname ) 
        {
            for (int i = 0; i < g.ColumnModel.Columns.Count(); i++)
            {
                string sql = "insert into myDbGridConfig (language, user, object, id_progr, text, width, fhidden) values (";
                sql += "'French','myUser','" + savegridname + "'," + i.ToString() + "'";
                sql += g.ColumnModel.Columns[i].Text + "',";
                sql += g.ColumnModel.Columns[i].Width.Value.ToString() + ",";
                sql += g.ColumnModel.Columns[i].Hidden.Value.ToString()+")";
            }
        }

Hi @tanky65,

The GridPanel and its Columns widths are not submitted to server automatically.

You should send them to a server manually. For example, via extra parameters of a DirectEvent or a DirectMethod.

ah thanks, I should treat them via extraparams for example by passing GetState() of the gridpanel encoding and then decoding to get again the values.
I'll try in this way.
Thanks again

fyi, what I did is the following:

                <DirectEvents>
                    <Click OnEvent="getGridConfig">
                        <ExtraParams>
                            <ext:Parameter Name="GConfig" Value="Ext.encode(App.GridPanel1.getState())" Mode="Raw" />
                        </ExtraParams>
                    </Click>
                </DirectEvents>

and in behind code

    protected void getGridConfig(object sender, DirectEventArgs e)
    {
        string config = e.ExtraParams["GConfig"];

        if (string.IsNullOrEmpty(config))
        {
            return;
        }

       // treat the string as XML structure and handle the content
    }
