Focusing or selecting the row, after grid load - grid

Question

I have a jsp page with button.
On clicking of the button, it creates a dojo grid dynamically.
After grid gets loaded, am iterating through the grid and if particular value is there, the whole row get selected.
I achieved it by using the below code, row gets selected, but am getting an error.
Error: "error: dojo.data.ItemFileReadStore: Invalid item argument"
Am using dojoX.grid.DataGrid(1.7)
Here is the code to create the dynamic grid:
var ioArgs = {
url: "./DynamicDBServlet",
content: { TABLE_NAME:tableName,WHERE_CONDN:condtn,COLUMNS:gridColumnName,ACTION:'select'},
handleAs: "json",
load: function(response) {
//alert(response["items"][0].USER_ID);
var tbl = document.getElementById(gridID);
//alert(tbl);
if(tbl) tbl.parentNode.removeChild(tbl);
var gridLayout = [];
var key;
colmn=gridColumnName.split(',');
var i=0;
while(i<colmn.length) {
if(colmn[i]=="STATUS"){
key = colmn[i];
gridLayout.push({
field: key,
name: displayName[i],
formatter:function(opvalue){
//alert(opvalue);
opvalue = parseInt(opvalue);
if(opvalue==1){
return "Executing";}
if(opvalue==2){
return "Suspended";}
if(opvalue==3){
return "Completed";}
if(opvalue==4){
return "Aborted";}
if(opvalue==5){
return "Error";}
if(opvalue==6){
return "Terminated";}},
width: '200px',
editable: false});
i++;
}if(colmn[i]=="PRIORITY"){
key = colmn[i];
gridLayout.push({
field: key,
name: displayName[i],
formatter:function(opvalue){
if(opvalue==1){
return "High";}
if(opvalue==8){
return "Normal";}
if(opvalue==15){
return "Low";}
},
width: '200px',
editable: false});
i++;
}if(colmn[i]=="PROCESS_METADATYPE"){
key = colmn[i];
gridLayout.push({
field: key,
name: displayName[i],
formatter:function(opvalue){
if(opvalue==4497){
return "Provisioning Sub Process";}
if(opvalue==4496){
return "Provisioning Loop";}
if(opvalue==4494){
return "Main Process";}
},
width: '200px',
editable: false});
i++;
}if(colmn[i]=="ORDER_TYPE"){
key = colmn[i];
gridLayout.push({
field: key,
name: displayName[i],
formatter:function(opvalue){
if(opvalue==4488){
return "Training Order";}
},
width: '200px',
editable: false});
i++;
}else{
key = colmn[i];
gridLayout.push({
field: key,
name: displayName[i],
width: '200px',
editable: false});
i++;
}
}
//alert(gridLayout);
var gridStore = new dojo.data.ItemFileWriteStore({
data: response
});
var dumm = dijit.byId('dynamicgrid'+tableName);
if(dumm) {
dumm.destroy();
}
var finderResponse = new dojox.grid.DataGrid({
id:"dynamicgrid"+tableName,
query: { },
store:gridStore,
structure: gridLayout,
selectionMode: "single"
}, document.createElement("div"));
dojo.byId(parentDiv).appendChild(finderResponse.domNode);
//var varb=dijit.byId("finderResponseGrid"+tableName);
//alert(varb);
//varb.layout.setColumnVisibility(0, false);
gbshowgridFlag = true;
finderResponse.startup();
//dijit.byId('dynamicgridCWPROCESS').focus.setFocusIndex(0);
try{
for( var i=0; i < dijit.byId('dynamicgridCWPROCESS').rowCount; i++){
var items = dijit.byId('dynamicgridCWPROCESS').getItem(i);
var value=dijit.byId('dynamicgridCWPROCESS').store.getValue(items,"PROCESS_ID");
if(value=="2507"){
dijit.byId('dynamicgridCWPROCESS').selection.setSelected(i,true);
}
}
if(defineDbl){
getProcessgrid();
}
}catch(e){
alert(e);
}
},
error: function(error) {
alert("An unexpected error occurred: " + error);
}
};
var deferred = dojo.xhrPost(ioArgs);

Answer 1

This code help me to select row in grid :
grid.selection.select(rowIndex);
In your case:
finderResponse.selection.select(rowIndex);
I hope this will solve your problem.

Answer 2

function selectRowByYourOwn(){
var row = null;
// you have to get is some have.. try onSelected='yourOwnFn', on your table tag or your div tag.
// function yourOwnFn(rowID){ row = rowID;}
grid.selection.clear();
grid.selection.setSelected(row, true);
grid.render();
}
