Button on one grid to refresh another grid

[Pat Bremkamp]

Sorry to ask this yet again...I know it has been discussed a lot, but I've searched for several hours and can't find it. Maybe one of you can point me to it or just tell me the answer.

I have two independent grids in a page in a tabbed UI. One grid, "job_selected", just shows one row of data indicating the selected job. The second grid, "job_select" is a list of jobs and has a "select" button on each row to pick a job and make it the selected job. So, the user comes to the page, searches in job_select for the job and clicks the button. I do an ajax callback to set a session variable and then use that session variable to filter job_selected and all the rest of the grids and pages. That works, but I can't get the job_selected grid to refresh. If I refresh the page manually, I can see the selected job, but I just want to refresh the grid from the button.

So, in grid "job_select" is a button that runs the Xbasic callback function "selectJob" that sets
e.session.__protected__jobid = e.currentRowKeys[1]

Then, I think, in the callback, I want to set a flag in a JavaScript variable that says the callback has been run, so I tried
selectJob = "sjCallbackFlag = true;"
and
selectJob = "var sjCallbackFlag = true;"

Then in the afterAjaxCallbackComplete system event, I want to check the flag, do the refresh and set the flag to false. Here my JavaScript fails me... I entered

if (svRunFlag == true) {
JOB_SELECTED_GridObj.refresh();
svRunFlag = false;
}

I don't get any errors, but nothing happens. I'd appreciate some help.

Re: Button on one grid to refresh another grid

I had a similar problem.
In the afterAjaxCallbackComplete, instead of using the flags use the e.ajaxEvent object.
This object lets you check the exact Ajax procedure that made the callback:

if (e.ajaxEvent=='saveGridData')
{
{grid.Object}.refresh();
}

I hope this helps you.
If you can, use window vars instead of session vars, development is much faster as they also work in the "Working Preview":

This writes a window variable:

window['win_id_hoja']=id_hoja;

And this reads the variable:

id_hoja=window['win_id_hoja'];

They are available to all grids on the same page.

I use this code to update the parent grid from the child grid (it is not a TabbedUI like you have):


//Get parent grid...
var po = {grid.object}.getParentObject();

//If this Grid does not have a parent then 'po' will be false.
//Refresh parent grid...
if(po) po.refreshLinkedContent();

Probably this doesn't work in a TabbedUI.

Finally you can always use Linked Grids instead of TabbedUI. If they don't have a single filed you can use to link them, you can always create a dummy field...

Re: Button on one grid to refresh another grid

This sounds like what I need, but I couldn't get it to work.

Is e.ajaxEvent the name of the Xbasic function?

This is javascript.

In the event afterAjaxCallbackComplete type:

alert(e.ajaxEvent);

And you will get a message each time a callback is finished, with the name of the callback.
