Hi

I am trying to hide / show the add / delete row buttons on specific rows of the igTreeGrid.

I followed your code suggestion but it does not do anything on the screen.

Thanks for your help.

here is my code:

<table id="treegrid1" dir="rtl"></table>

$("#treegrid1 > tbody > tr").hover(
function(evt) {
alert(1);
var rowID = $(this).attr("data-id"); // Get the row id.
if (hasChildren(rowID)){
$("span.ui-iggrid-deletebutton").hide();
}
else
{
$("span.ui-iggrid-deletebutton").show();
}
},
function(evt) {
alert(2);
$("span.ui-iggrid-deletebutton").show();
}
);

var TheGrid ;
var ParentRow;

$(function () {
$('#divErrMsg').hide();
//append the elements to the page
TheGrid = $("#treegrid1");

TheGrid.igTreeGrid({
width: "100%",
//dataSource: gridData, //bound to flat data source,
autoGenerateColumns: false,
primaryKey: "bgt_rowid",
foreignKey: "bgt_prowid",
initialExpandDepth: 0,
updateUrl: "Services/BudgetService.asmx/Update",
autoCommit : true,
columns: [
{ headerText: "שם", key: "rowName" , width: "300px" , dataType: "string" },
{ headerText: "rowID", key: "bgt_rowid", width: "100px", dataType: "number" , hidden: true},//must column. without it the grid is not working properly.
{ headerText: "ParentID", key: "bgt_prowid", width: "100px", dataType: "number", hidden: true },//must column. without it the grid is not working properly.
//dynamically add columns
<%
foreach (Builder.Tarbut.DAL.BudgetColumn col in GridCols) {
Response.Write(string.Format("{{ headerText: \"{0}\", key: \"{1}\", dataType: \"number\" }},", col.ColTitle, col.ID));
}
%>
