Hi,

I got the hierarchical grid working without ODATA,I am able o send the GET request to the server on expand and fetch the customized data. But, I have another issue, HOW CAN I CUSTOMIZE THE REQUEST sent to server.

My configs:

function getColumnConfigurationByLevels(configs,levels,businessDate){

var jsonData = new $.ig.JSONPDataSource({
dataSource: "myURL",
type: "remoteUrl",
requestType: 'post'
});

var hierarchicalGridConfigs={
width: "100%",
initialDataBindDepth: 0,
dataSource: jsonData,
oData:false,
rest:false,
autoGenerateLayouts: false,
autoGenerateColumns:false,
key:"myDate",
primaryKey:"id",
columns:getDefaultColumns(),
columnLayouts: getColumnLayouts(0,configs,levels-1)

};
return hierarchicalGridConfigs;
}
function getColumnLayouts(i,configs,levels){
var layouts=[];
var layout1={};
layout1["autoGenerateColumns"]= false;
layout1["odata"]= false;
layout1["primaryKey"]="id";
layout1["key"]=getKey(configs);
layout1["columns"]=configs[i];
if(i<levels){
layout1["columnLayouts"]=getColumnLayouts(++i,configs,levels);
}
layouts.push(layout1);
return layouts;
}

 
I am able to hit server on that URL, with parameters appended by igNite UI, but i want to customize it because I will NOT necessary send only key or primary key to server. I can need more information. How can i customize it.

When I click on expand button, URL generated is like myURL?id:value&layout:layout&pk=id&_=someNumber

 Layout: is the key that I provides in the child layouts
ID: is Id of parent

I am not able  to customize it

I want
1) A POST REQUEST
2) More customized parameters wher eI can send other information that primary key of parent grid 

Hi,

I am trying what you said. A few issues:

1)  ui.owner.options.requestType = "POST"; option is not there
2) I need to pass some parameters in the request, the parameters will be from parent row, how can i get those parameters??

I am able to change the datasource URL as told by you, it is working,but still facing issue in parameters (from parent grid row) and changing to POST 

Sorry to revive an old thread, but this approach seems to be what I'm looking for.  I am getting the following error when I try to set the .dataSource in the last line to a web API URL (which does work correctly when requested in Fiddler):

"There was an error parsing the JSON data and applying the defined data schema: Cannot read property 'Metadata' of null"

Can anyone help me with what I am doing wrong? 

Hello Vivek Vardhan,

I'm glad that you find this information helpful.

Please let me know if you need further assistance with this matter.

Hello Vivek Vardhan,

The ui.owner.element.parents("tr[data-container='true']").prev() will return you all the parent rows up in the hierarchy. And the ui.owner.element.parents("table.ui-iggrid-table") will return you all the parent igGrid instances up in the hierarchy. You just need to iterate over them and extract the required information.

Hope this helps,

Hi,

Thanks for your help. one last question in this context is:

var parentRowId = ui.owner.element.parents("tr[data-container='true']").prev().data("id"),

parentGrid = ui.owner.element.parents("table.ui-iggrid-table").data("igGrid"),

parentRowData = parentGrid.findRecordByKey(parentRowId);


Above statements are helping me in getting the parent row data, but suppose there are multiple levels of grid in hierarchy. How can I get the data of all the ancestors?
