Hi All

How to add extra parameter to server request when I click next page?

By default, when next page click , PagingToolbar send request to server with parameters start=x&limit=x,

but i need include one more which is my parent grid selected record id.

How do i do that?

You have to check the store object. From there the parameters are submited.
For ex
store.lastOptions.params.yourParem = value;

Sorry I still dont understand.

this is my Store:

var MonthlyReportStore = new Ext.data.Store({
autoLoad: true,
proxy: MonthlyReportProxy,
reader: MonthlyReportReader,
writer: MonthlyReportWriter,
autoSave: true,
batch: false,
paramsNames: { start: 'start', limit: 'limit', CompanyId:'CompanyId' },
baseParams: { start: 0, limit: 12, CompanyId:-1}
});This is my parent grid's listener listen to the rowclick event to reload my child grid:

listeners: {
rowclick: function (g, index, ev) {
var rec = g.store.getAt(index);
grid_CompanyID = rec.get('ID');
MonthlyReportStore.reload({ params: { CompanyId: grid_CompanyID} });
}It works fine at the parent grid's row click, this is the server request got sent:


but after that, when I clicked next page in the child grid, the CompanyId parameter became the baseParams value from the store:

What I want is when I clicked next page in the child grid, the CompanyId should be my parent grid selected record id.

Is this possible?

Wrong answer. You need to store the parameters in the store baseParams, e.g.

detailStore.baseParams = {
id: masterId
params: {
start: 0,
limit: 20
